ZnO nanorods are currently studied for variety optoelectronic applications. Typically, thin film and bulk ZnO show a strong light absorption in the ultra violet (UV) range. For devices that operate in the visible and infrared range such as optoelectronic sensors and photovoltaic cells, it is necessary to modify the ab…
Accurately and rapidly predicting the shrink mold shape of direct injection-expanded foam molding is an important and difficult task. This molding method is widely used by sports shoe sole manufacturers to create shock-resistant materials. Modifying the shrink mold shape using the numerical optimization method is cruc…
A hierarchically porous chitosan–PEG–silica (CPS) biohybrid has been prepared in a facile synthesis through in situ silica polycondensation within a chitosan–PEG hydrogel. This organic–inorganic composite is almost non-toxic and has quick cell-adsorptivity. As a result of its unique hierarchical structure and excellen…
The skin is the largest human organ. Its care and health are, therefore, essential. The skin can only be healthy and attractive when it is in balance. The pre-requisites for healthy skin are: the moisture content, the protective function, elasticity and cell renewal. All of these parameters are supported by applying p…
We demonstrate a woven textile with an integrated humidity and temperature sensor on flexible PI substrates. We discuss the fabrication process of the smart textile and compare two methods of sensor fabrication, first conventional photo lithography and second printing using ink jet. The humidity sensor is based on a c…
A series of surface-modified expanded poly(tetrafluoroethylene) membranes showed varied levels of in vitro macrophage proinflammatory response. Membranes containing a mixture of phosphate and hydroxyl groups (as determined by X-ray photoelectron spectroscopy analysis) stimulate greater macrophage activation than sampl…
That protein folding is a non-random, guided process has been known even prior to Levinthal's paradox; yet, guided searches, attendant mechanisms and their relation to primary sequence remain obscure. Using extensive molecular dynamics simulations of a β-hairpin with key sequence features similar to those of >13,000 β…
This paper highlight the most important areas and directions of shape memory polymers in textiles. The textiles of shape memory polymers involve fibre spinning (including wet-spinning, melt-spinning and electro-spinning), fabric, smart apparel, actively finishing technology and WVP investigation. Based on the molecula…
Protonated pyrrole cations are produced in a pulsed discharge/supersonic expansion source, mass-selected in a time-of-flight spectrometer, and studied with infrared photodissociation spectroscopy. Vibrational spectra in both the fingerprint and C-H/N-H stretching regions are obtained using the method of tagging with a…
Abstract Reaction of different ratios of manganese(II) thiocyanate with pyridazine in water at room temperature leads always to the formation of the pyridazine‐rich 1:4 compound (1:4 = ratio between metal and neutral co‐ligand) Mn(NCS)2(pyridazine)4 (1). In the crystal structure of 1, the Mn2+ cations are coordinated…
A series of new coordination polymers based on p-tert-butylcalix[4]arene- tetracarboxylic acid with Eu3+ (1a), Tb3+ (1b) and Tm3+ (1c) were prepared by hydro and solvothermal methods. The obtained solid compounds were characterized by infrared and luminescence spectroscopy, powder X-ray diffraction, scanning electron…
The study deals with peculiarities of hydration and development of hardening structure as well as durability properties pertaining to composite anhydrite cement pozzolana binder (ACP) with different pozzolana (P). The properties of P have an effect on ACP hydration, structure development and durability properties. Thi…
Telah dilakukan sintesis MT (magnesium titanat) dengan metode pencampuran larutan. Prekursor dibuat dengan melarutkan serbuk logam ke dalam HCl 37% dan dikeringkan di udara pada temperatur 110 o C dilanjutkan dengan kalsinasi. Dalam penelitian ini digunakan variasi temperatur kalsinasi yaitu 600°C, 700°C, 800°C dengan…
Ethylene vinyl acetate (EVA)/ Cloisite® 20A (C20A) composite fabricated via the melt-blending method was used for the development of a heavy-metal adsorbent through acid and heat treatment. Heat-treated composites were produced at 400°C to 1 000°C in air and N2 atmospheres. The materials were characterised through TGA…
In order to improve comfort of smart garment, rigid electronic boards can be replaced with textile circuits, which use conductive yarns. When one tries to improve wearing comfort, often the most problematic items turn to be connection points of the electronic circuitry. The aim of this research is to determine behavio…
In nature, molecules exploit interaction with their environment to realize complex functionalities on the nanometer length scale. Physical, chemical and/or biological specificity is frequently achieved by the switching of molecules between microscopically different states. Paradigmatic examples are the energy producti…
Abstract Sn(0)‐mediated single electron transfer‐living radical polymerization (SET‐LRP) of acrylonitrile (AN) with carbon tetrachloride (CCl4) as initiator and hexamethylenetetramine (HMTA) as ligand in N, N‐dimethylformamide (DMF) was studied. The polymerization obeyed first order kinetic. The molecular weight of po…
In reactive High Power Impulse Magnetron Sputtering (HIPIMS) of oxides, target effects such as reduced surface oxidation during pulse off time, increased implantation of reactive gas due to the higher discharge voltage as compared to normal DC sputtering, and enhanced target cleaning during on time are considered to b…
Carbon nanotube (CNT) functionalized probes are expected to offer better resolution in Kelvin probe force microscopy (KPFM) but are suspected of lower sensitivity because of the small area between the CNT end and the sample surface. This paper quantitatively analyzes the resolution and sensitivity of KPFM using CNT fu…
Adipose-derived stem cells (ASCs) can differentiate into smooth muscle cells and have been engineered into elastic small diameter blood vessel walls in vitro. However, the mechanisms involved in the development of three-dimensional (3D) vascular tissue remain poorly understood. The present study analyzed protein expre…
