Abstract: The blood-brain barrier (BBB) represents an insurmountable obstacle for the delivery of a large number of drugs to the central nervous system (CNS). One of the possibilities to overcome this barrier is drug delivery to the brain using nanoparticles. Drugs that have been transported into the brain and led to a pharmacological effect after intravenous injection using this carrier include the hexapeptide dalargin, the dipeptide kyotorphin, loperamide, tubocurarine, doxorubicin, and the NMDA receptor antagonists MRZ 2/576 and MRZ 2/596. To achieve a significant transport across the blood-brain barrier the coating of the nanoparticles with polysorbate 80 (Tween® 80) was a key factor. Experiments with the extremely aggressive glioblastoma 101/8 transplanted intracranially showed a long term survival for 6 months of up to 40 % of the rats after intravenous injection of the polysorbate 80-coated nanoparticle preparation. The surviving animals showed a total remission by histological investigation. Untreated controls died within 10 - 20 days, the animals in the doxorubicin control and uncoated doxorubicin nanoparticle groups died between 10 – 50 days. The mechanism of the drug transport across the blood-brain barrier with the nanoparticles appears to be endocytotic uptake by the brain capillary endothelial cells followed either by release of the drugs in these cells and diffusion into the brain or by transcytosis. After injection of the nanoparticles, apolipoproteins A-I or E adsorb on the particles surface promoting the interaction with receptors on the endothelial cells followed by endocytotis and thus would the uptake of naturally occurring lipoprotein particles. This hypothesis was supported by the achievement of an antinociceptive effect with loperamide-loaded albumin nanoparticles with covalently bound apo E and by electron microscopy. The cardiac, and testicular toxicity of doxorubicin was very significantly reduced by binding the drug to poly(butyl cyanoacrylate). In addition the haematological and liver toxicity could be reduced. Coating of PBCA nanoparticles with polysorbate 80 contributed to the reduction of the toxicity. The lower toxicity of the nanoparticle formulations can be most probably explained by the altered biodistribution of the drug mediated by the nanoparticles. Indication of short-term neurotoxicity were entirely absent in the rats on day 12 as well as in long-term survivors. Similar nanoparticles loaded with doxorubicin were manufactured using poly-(lactic-co-glycolic acid) (PLGA) and tested in humans in a Clinical Phase I trial. The nanoparticles were well tolerated and are now tested in Clinical Phase II against glioblastomas.

He is well-known globally, for work on surface plasmons and guided wave optics, nonlinear waves and solitons and nonlinear guided magnetooptic waves in metamaterials.

Abstract: Hyperbolic metamaterials are becoming popular artificial materials that can deploy advanced graphene structures, and uniaxial layered dielectric systems. A major feature is that a layered sub-wavelength system is experimentally attractive and, relatively, easily controlled. New pathways for this sort of hyperbolic metamaterial are revealed here leading to novel behaviour of rogue waves. They show how nonlinearity and elegant magnetooptic control can be readily included, through a novel methodology based around forms of the nonlinear Schrödinger equation [NLS] that include stationary and non-stationary effects. It can be difficult to generate the NLS for hyperbolic metamaterials but the developments shown here, based upon type II hyperbolics, permit the investigation of both temporal and spatial solitons. Additionally, the possibility of terahertz wave amplification in hyperbolic metamaterials, basedupon graphene with inverse population of carriers in the epsilon-near-zero regime is demonstrated. Type II metatamaterials will be fully investigated with the inclusion of nonlinear, non-stationary diffraction and dispersion. These are important, and active, planar hyperbolic metamaterials. New types of soliton interaction devices and a fascinating discussion of rogue waves will be presented. It is shown that the optic axis must always be in a carefully frozen position, for all applications. Indeed, its position is so dominant that it could overwhelm absorption, for example. Controlled generation of high-intensity single- or multi- rogue waves will be demonstrated by induced modulation instability leading to some new broad-based applications, including biological.

Abstract: The structure of a series of mineral micro-particles of terrestrial and extra-terrestrial origin (lunar soil, meteoritic substance) was investigated by laser micro-Raman spectroscopy as a non-destructive structural methods. Various modifications of sp2 carbon were disclosed in lunar soil and meteoritic substance, these were compared with different carbonaceous materials of terrestrial origin (diamond, natural graphites and shungites) and with industrial man-made materials (grapheme, hexagonal and turbostratic graphites, glassy carbon, diamond-like carbon, nanotubes, carbon fibers, etc ). This was possible because each modification of sp2 carbon exhibits its own specific Raman spectrum, characterized by a given number of Raman lines with particular parameters (frequency, intensity, half-width, contour). In Fig. 1 the Raman spectra of are juxtaposed of carbonaceous matter of lunar soil , “Chelyabinsk” metheorite and terrestrial Karelian shungite. Fig.1 Raman spectra of the are juxtaposed of carbonaceous matter of terrestrial Karelian shungite (1), lunar soil (2) and “Chelyabinsk” metheorite (3). The results obtained for terrestrial and extra-terrestrial samples has allowed us to conclude that these materials contain similar sp2 carbon modifications which speaks for the singleness of Nature laws.

Abstract: Magnetic nanoparticles have drawn attention recently due to their potential applications for diagnostics and therapies in the biomedical field. Previously, we prepared various kind of magnetic nanoparticles (MNPs) by an original wet chemical method, and reported magnetic, structural and thermal properties [1]. The obtained particles were functionalized for biomedical applications. We tried to introduce these functional particles into the living cells, and these particles were localized by the external magnetic field. Then cancer cell selective NPs were further developed by conjugating with folic acid [2]. Then, we proposed a therapeutic method of magnetic hyperthermia using our magnetic nanoparticles. It is known that imaginary part of magnetic susceptibility χ” affects heat dissipation of magnetic materials upon the AC magnetic field. AC magnetic measurements were performed and the relationship between the imaginary part of magnetic susceptibility χ” and the increase in temperature in the AC field was estimated. We have carried out in vitro experiments using cultured human breast cancer cells, and a drastic hyperthermia effect was observed [3]. On the other hand, magnetic resonance imaging (MRI) were used as one of the effective tools for diagnostics. We examined the MR relaxivity of our magnetic nanoparticles for various particle sizes and composition. The T2 relaxation curves were measured and the relationship between these MR relaxation rate R2 and physical properties was investigated by spin echo sequence. Our particle showed strong T2 shortening effect and clear contrast compared with the agarose as background was observed in phantom image. We also proposed mass spectrometric imaging (MSI) using our particles. With this method, the targeting analyte can be detected only with the nanoparticles as matricies, and simultaneously we can see the distribution of the materials by mapping the spectra. By means of our matrices, targeting analyte of very low molecular weight was successfully detected. Furthermore, we tried to evaluate if our particles even get through the blood-brain barrier through in vitro experiment. Our magnetic nanoparticles would be useful for diagnostics and therapies, introducing a development of theranostics.

Christoph Doering
Integrated Optoelectronics and Microoptics Research Group, Germany
Title: nm-Sensitive In-Situ and Real-Time Etch-Depth Control with Reflectance Anisotropy Spectroscopy (RAS) during Reactive Ion Etching (RIE)

Biography: Christoph Doering was born in Rockenhausen, Germany, in 1978. He received the M.S. and Ph.D. degrees in physics both from TUK, Germany, in 2004 and 2007, respectively. Since 2004, he has been working in the “Integrated Optoelectronics and Microoptics” research group of Prof. Fouckhardt in the Physics Department at TUK. His current research interests focus on integrated optical systems like transverse mode selectors for broad-area lasers, on antimonide-based semiconductor lasers, and on microfluidic devices with optical manipulation and detection. Dr. Döring is a member of the Deutsche Physikalische Gesellschaft (DPG) and the German Chapter of the International Radiation Protection Associ-ation (IRPA).

Abstract: A measurement technique, i.e. reflectance anisotropy spectroscopy (RAS), which had originally been developed for in-situ epitaxial growth control by Aspnes, Harbison et al. [1,2], is employed for in-situ and real-time etch-depth control during reactive ion etching (RIE) of crystalline III/V semiconductor samples here. - Typically temporal optical Fabry-Perot oscillations of the reflected light intensity during etching due to the etch-related shrinking layer thickness are used to monitor the current etch depth. This way etch-depth resolution is better than 20 nm [3]. – Moreover, some preliminary results indicate that for small etch rates, that is below app. 50 nm/min (limited due to the data collection time of the RAS elec-tronics), the resolution might even be one atomic layer. In that case the oscillations would be related to local ordered anisotropies of atomic scale at the crystalline surface, i.e. at the etch front.

Abstract: Water based acrylic emulsion is environment friendly and has excellent properties of light stability, heat resistance, weather fastness, high color retention, and low cost, so it shows good development prospect in the exterior wall coating market as a kind of film forming material of acrylic coating. Since it is difficult for exterior wall coating made from ordinary acrylic emulsion to meet the high end application requirements due to the fact that it has poor temperature resistant denaturation and is apt to crack, hyperbranched hydrogenated styrene butadiene rubber (HES) was applied for the modification of acrylic emulsion with the method of interpenetrating network to improve performance of acrylic emulsion and structure design research of HES modified with hydrophilic end groups was carried out to provide a reference for acrylic emulsion interpenetrating network modification. Based on highly branched structure characteristics of the hydrophilic end group modified HES, the theoretical calculation of feasibility of HES self-emulsification was carried out, which shows that HES with hydrophilic end groups can be self-emulsified to a certain extent and has certain feasibility of interpenetrating network modification for the acrylic emulsion of which particle size ranges 100-200nm. HES with more branches has stronger selfemulsifying ability after modified with hydrophilic end group.

Dmitry A. Indeitsev

Title: Problems of Describing Structural Transformations in Solids

Biography: Professor D.A.Indeitsev is the corresponding member of RAS. From 2015 he takes the position of the scientific adviser in the Institute for Problems in Mechanical Engineering. At the moment he is also the head of the chair “Mechanics and Control” in St. Petersburg Polytechnic University. He is the member of the editorial board of well-known international journals “Acta Mechnica” and “Reviews on Advanced Materials Science”.

Abstract: The present paper is devoted to the problem of describing materials capable of structural transformations. Basing on two-component model of material with nonlinear internal force, we investigate the existence of non-stable constitutive curve containing a decreasing segment, which is widely used in many papers concerning phase transitions of materials. For this purpose a kinematic loading of two-component rod is considered. The main goal is to determine the influence of the relative displacement on the stress-strain dependence and to establish the expression, connecting the position of the critical point on the diagram with the parameters of the microstructure. In the second part of the work we consider a non-stationary problem of crystalline lattice transformation under loading. Using the analogy between the continuum equations and the corresponding discrete model, we carry out the investigation of the quenching of a non-stationary wave due to the dissipation of energy into structural conversions and estimate the duration of this process. The obtained analytical results are compared with the numeric calculations performed by finite difference method.

Abstract: Considerable efforts have been undertaken within the past decades to shift organic-based thin-film devices from basic research to the application level. In this talk, avenues toward the realization of organic electronics on the basis of ultrathin functional organic layers are outlined, specifically by leveraging on the self-assembly process at interfaces. In the first part, we show how large area molecular junctions of outstanding robustness can be realized using densely packed molecular metal-terpyridine complex oligomers, which might enable a versatile platform for functional optoelectronic layers.1 In the second part, a new class of self-assembled monolayers2 exhibiting a pronounced intrinsic dipole moment is presented, by which the injection properties in organic semiconductors can be tuned in view of in solar cell and organic memory applications.3 Finally, as an example for biomolecular photoconductors, Sn-cyt c protein layers are shown to act as reversible photo-electrochemical switches upon integration into large area solid state junctions.4The underlying modulation in charge transfer rate is attributed to a hole-transport channel, created by the photoexcitation of the Sn-porphyrin.

Sean Perry

He is currently a technical leader for a project including the remediation of sulphates and nitrates, His daily activities entails; Technical problem solving Technology implementation on industrial pilot scale Product development, Bead manufacturing process design, Bead manufacturing process optimisation.

Abstract: The environmental application of chitosan supported by sisal to remove Cr (VI) ions from aqueous solutions and Cr6+, Mn2+ and SO4- from AMD was investigated. The experimental conditions that enhance the adsorption of Cr (VI) from aqueous solutions and Cr6+, Mn2+ and SO4- from AMD by sisal/chitosan composite have been analysed. These conditions include the initial concentration of Cr (VI), pH, the dose of adsorbent, contact time and co-existing ions effect. The optimum mass was reached at 1.5 g dosage of sisal/chitosan composite. The research confirmed sisal/chitosan composite is an effective adsorbent for the removal of Cr6+ (aqueous solutions) and Cr6+, Mn2+ and SO4- from AMD. The SC3 has proven to have affinity towards sulphates, manganese and chromium. The average of 97% removal is achieved in all the metals and sulphate. The adsorption of Cr6+, (aqueous solutions) and Cr6+, Mn2+ and SO4- from AMD by sisal/chitosan composite was an exothermic process. Maximum Cr6+, Mn2+ and SO4-removal occurred at pH 2.0. The analysis of ICP revealed that there is 14.01 mg/L of manganese, 80 mg/L chromium and 6534 mg/L of sulphates present in the AMD sample. The maximum adsorption capacity of sisal/chitosan composite (SC3) for Cr (VI), aqueous solutions, removal was found to be 162.3 mg/g and obtained high maximum adsorption capacity of around 200 mg/g for sulphates, manganese and chromium, AMD, at 25 0C respectively. The SEM analysis was performed to confirm the effect of the blend between sisal and chitosancomposite; chitosan is firmly embedded into polymer fibre layer, even though some gaps between the fibre and chitosan were still noticed.

D.I. Beketova
Nikolaev Institute of Inorganic Chemistry Siberian Branch of Russian Academy of Sciences Novosibirsk, Russia
Title: A novel emulsion approach to the production of stable concentration silver organosols

Biography: Beketova Darya received her B.S. (2010) from Department of Natural Sciences, Novosibirsk State University working on design of capillary columns for gas chromatography. Then she worked at Nikolaev Institute of Inorganic Chemistry Siberian Branch of Russian Academy Sciences to study microemulsion crystallization of water-soluble salts in mixture of surfactants receiving her Ph. D. degree in 2014. She has published 5 articles, three of them were published in journals of American Chemical Society. Now she continues to study a behavior of water-soluble salts in reverse micelles and her research focuses on development of productivity of micellar crystallization.

Abstract: Stable highly concentrated organo- and hydrosols of metal, oxide, and salt nanoparticles are promising as inks for printing of microcircuits, optically active media for random lasers, and starting components for the formation of various functional nanomaterials. One of the most popular methods for the production of organosols and ultradispersed powders is a microemulsion (micellar) synthesis. The drawback of the injection-microemulsion synthesis is the low concentration of nanoparticles in the obtained dispersions. Emulsion synthesis permits to obtain microparticles of high productivity. We tried to combine the advantages of both techniques. Sodium bis-(2-ethylhexyl)sulfosuccinate (AOT), an anionic surfactant, is used as a common micelle-forming agent. Starting reagents were successively introduced into a micellar solution of AOT in n-decane in the dynamic reverse emulsion mode. During the contact of the phases, Ag+ pass into micelles and Na+ pass into emulsion microdroplets through the cation exchange AOTNaOrg+AgNO3Aq=AOTAgOrg+NaNO3Aq. High concentrations of formed NaNO3 and hydrazine in the microdroplets favor an osmotic outflow of water from the micelles, which reduces their polar cavities to ~2 nm. As a result, silver ions are contained in the micelles, and the reducing agent is present mostly in emulsion microdroplets. The reagents interact in the polar cavities of micelles to form ~7 nm Ag nanoparticles. The small size of micelles limits the growth of nanoparticles; the nanoparticles do not coagulate. The produced nanoparticles are positively charged, which permitted their electrophoretic concentration to obtain liquid concentrates (up to 30% Ag) and solid Ag-AOT composite (up to 75% Ag). Their treatment at 250°C leads to the formation of conductive films (180 mOhm per square). The developed technique makes it possible to increase the productivity by ~30 times and opens up new avenues of practical application for the well-studied microemulsion synthesis.

Abstract: Ferrite powders containing nickel, zinc and different amounts of copper are typically used as electromagnetic wave absorbers. It is very difficult to control the absorption capacity of a given material, as the attenuation properties of electromagnetic wave absorbers depend on several factors, such as complex permeability, complex permittivity, frequency, and thickness. Moreover, certain magnetic properties such as the saturation magnetic moment depend only on the material’s chemical composition, whereas others, such as permeability loss, also depend on other factors, of which material microstructure is the most critical. Thus, for a material to act satisfactorily as an electromagnetic wave absorber, high sintered relative density (low porosity), little average grain size growth, and narrow grain size distribution width are required. Numerous studies have shown that the mechanical and/or physical properties of ceramic bodies improve when particle-size distribution decreases from the microscale to the nanoscale. The sintering stage has been study in order to control the evolution of grain growth and densification with sintering temperature when nanoparticles powders are used. The microstructure of the sintered ferrites has been analysed by SEM, determining the grain size distribution, pore size distribution and grain boundary morphology. The imaginary part of complex permeability of the sintered ferrites has been determined and correlated to the microstructure parameters of the sintered bodies. These results have been compared as well with the ones obtained using microparticulated powders.

Title: Numerical analysis of the specific behavior of interfacial phenomena in nanoscale

Biography: Kyoichiro Urano graduated from the Department of Chemical Science and Engineering in Osaka University in Japan, and is a Master course first year student in the Division of Chemical Engineering in the Department of Materials Engineering Science in Graduate School of Engineering Science of Osaka University in Japan. His research is about transport phenomena in nanoscale.

Abstract: This study focuses on Marangoni convection driven by surface tension gradient in the flow with a gas-liquid interface in nanoscale. The flow in the nanoscale interface has properties between gaseous and liquid in the nanoscale, and the velocity of the fluid is promoted because the fluid in the interface has lower viscosity than that in the bulk liquid region. In this research, the influences of viscosity on Marangoni convection and the characteristics of the gas-liquid interface were investigated by using the molecular dynamics simulation(MD). Solutes which have different viscosities are applied to the simulation system, and the shape of the liquid film and the distribution of the gas-liquid interface thickness along the interface are calculated by the MD simulation. The results show that the width of the liquid film reduces around a water-solute boundary when the viscosity of solute is large, and that the interface thickness increases locally around the water-solute boundary. Around the water-solute boundary, the intermolecular interaction reduces and so the interface thickness increases. As the gas-liquid interface thickness increases, the viscosity of the fluid in the interface decreases. It is found that the acceleration of the fluid velocity in nanoscale is caused by the local increase of the gas-liquid interface thickness.
