Novel excellent hydrophobic- mesoporous- polymer-based solid acid catalysts have been successfully synthesized by copolymerization of divinylbenzene (DVB) with sodium p -styrene sulfonate (H-PDVB- x -SO 3 H's) under solvothermal conditions. N 2 isotherms and TEM images showed that H-PDVB- x -SO 3 H's have high BET sur…
The influence of water on the redox properties of ceria is pivotal to its widespread exploitation spanning a variety of applications. Ab initio simulation techniques based on DFT-GGA+U are used to investigate the water–ceria system including associative (H 2 O) and dissociative (−OH) adsorption/desorption of water and…
We demonstrate, for the first time, an all-dielectric metamaterial composite in the midinfrared based on micron-sized, high-index tellurium dielectric resonators. Dielectric resonators are desirable compared to conventional metallodielectric metamaterials at optical frequencies as they are largely angular invariant, f…
We report an improved synthesis of colloidal gold nanorods (NRs) by using aromatic additives that reduce the concentration of hexadecyltrimethylammonium bromide surfactant to ~0.05 M as opposed to 0.1 M in well-established protocols. The method optimizes the synthesis for each of the 11 additives studied, allowing a r…
In the past decade, mesoporous silica nanoparticles (MSNs) have attracted more and more attention for their potential biomedical applications. With their tailored mesoporous structure and high surface area, MSNs as drug delivery systems (DDSs) show significant advantages over traditional drug nanocarriers. In this rev…
In this study, we investigated the possible use of a new inorganic material as alternative filler in the paper industry. The inorganic material is a mineral composed of calcium sulfate, that is generated when manufacturing phosphate fertilizer. The inorganic material was dehydrated by the thermal treatment to <TEX>$20…
Two commercial compatibilizers of ethylene glycidyl methacrylate (EGMA) and styrene-b-ethylene/butyleneb-styrene grafted with maleic anhydride (SEBS-g-MA) were added to poly(phenylene sulfide) (PPS)/poly(ethylene terephthalate) (PET) (80/20, weight ratio) and PPS/polyamide 66 (PA66) (80/20, weight ratio) mixture, resp…
The ITER fuel cycle is designed for DT operation in equimolar ratio. It involves not only a group of fuelling system and torus cryo-pumping system of the exhaust gases through the divertor from the torus in tokamak plant, but also from the exhaust gas processing of the fusion effluent gas mixture connected to the hydr…
Synchrotron x-ray diffraction and absorption, together with magnetic and thermoelectric measurements, have been used to investigate the mechanism driving the metal to insulator transition in YBaCo2O5.50. Results show a structural and magnetic transition concomitant with the metal to insulator transition. Absorption sp…
In this work, the silver nanoparticles have been synthesized by electrical explosion of wire in three liquid mediums: deionized water (DIW), polyvinylpyrrolidone (PVP) and sodium dodecyl benzene sulfonate (SDBS) solutions. Absorption in the UV-visible region of these suspensions was measured in the range of 300-800 nm…
Layer-by-layer SAMU thin films of azo dye molecules and PEL exhibited two distinct absorbance maxima in visible and UV regions. This is attributed to the assumption that a fraction of the dye adsorbed as the monomeric form yields a visible peak, while the additional fraction of the oligomeric H-type aggregated form al…
To develop a waterproof breathable material, we fabricated three kinds of nanofiber web laminates using a massproduced electrospun nanofiber web with different substrates and layer structures. The waterproofness and breathability of nanofiber web laminates were evaluated after repeated launderings and compared with th…
The on-going research on carbon nano beads (CNBs) are focusing on applications ranging from high strength composites, catalyst carriers, lubricants, electronic devices, weather resistant materials, molecular ball bearings, drug delivery vehicles (Bio-medical), semiconductors/transistors, high-capacity batteries and Hy…
We report on a python interface to the GROMACS molecular simulation package, GromPy (available at https://github.com/GromPy). This application programming interface (API) uses the ctypes python module that allows function calls to shared libraries, for example, written in C. To the best of our knowledge, this is the f…
The thermomechanical behavior of shape memory alloys is now well mastered. However, a hindrance to their sustainable use is the lack of knowledge of their fracture behavior. With the aim of filling this partial gap, fracture tests on edge-cracked specimens in NiTi have been made. Particular attention was paid to deter…
Polystyrene-b-polymethylmethacrylate (PS-b-PMMA) was selected as the host for 4-(4-nitrophenylazo)aniline (Disperse Orange 3, DO3) based on a previous study of DO3/PMMA and DO3/PS binary blends. Selective location of DO3 into the PMMA block of the copolymer was expected during self-assembly of the block copolymer sinc…
Repeating boundaries: the buried interfaces in artificial heterostructures produced by sequential deposition of nanosized units are critical to their properties. With density functional theory it was shown that in Y(2)O(3):ZrO(2) (YSZ) and SrTiO(3) (STO) heterostructures reconstruction of the interfaces between the co…
In batch culture for Poly(vinyl alcohol) (PVA)-degrading enzyme (PVAase) production by a mixed culture, higher pH (pH 7.5) was favorable for PVAase production at the prophase of cultivation, but lower pH (pH 7.0) was favorable at the anaphase. This situation was caused by the fact that the optimum pH for different key…
NiTi wires are successfully employed asthermal actuators: devices able to convert thermal energy into mechanical energy, generating force and displacement. So far, researchers have highlighted the influence of various parameters on shape memory characteristics of the material, such as chemical composition, cold workin…
For the first time, this work indicates that mechanical concerns of inorganic materials are highly demanded when well optimizing their functional applications. We quantitatively give the proper data of hardness on different planes of some representative inorganic functional materials including borides, carbides, nitri…
