The mechanism for the redox activity of electroactive polymers (EAPs) with unconjugated backbones (e.g., polyvinylferrocene, PVFc) is fundamentally different from that of intrinsically conducting polymers. Here we investigate, for the first time, the redox transformation efficiency (RTE) of unconjugated EAPs with disc…
Preparing chemically selective nanoparticle (NP) building blocks to make robust structures from different NP compositions often requires complex hetero-bifunctional ligand pairs that have limited scalability and versatility. Here we describe pentafluorophenyl ester-functionalized nanoparticles (PFP-NPs) as versatile b…
Recent improvements to SrAl2O4:Eu2+, Dy3+ phosphors have enabled the use of luminescent hosts with a stable crystal structure and high physical and chemical stability, thus overcoming the bottleneck in the applicability of ZnS:Cu phosphors. However, enhancement of afterglow lifetime and brightness in SrAl2O4:Eu2+, Dy3…
The abilities of the (HPO 3 ) 2– and (SeO 3 ) 2– anions as structure building units and as spin exchange paths between magnetic ions were investigated by preparing and analyzing the isostructural Fe 2 (SeO 3 ) 3 and Fe 2 (HPO 3 ) 3 . In both compounds, the face-sharing Fe 2 O 9 dimers are interconnected into chains by…
The nanocarrier capabilities of atomically smooth two-dimensional sheets of a biantennary oligoglycine peptide C8H16(-CH2-NH-Gly5)2 (also called tectomers) are demonstrated. We show that the pH-controlled, rapid, and reversible assembly and disassembly of oligoglycine can be effectively used for controlled loading and…
In this work, electrochemical double layer supercapacitors were fabricated using multiwalled carbon nanotube (MWCNT) composite microfilm as electrode. To improve the electrochemical properties, MWCNTs were functionalized with −COOH by acid treatments. CNT/PVA films have been deposited on different current collectors b…
The selection of a suitable fabric layer is an important aspect in the development of a cooling garment. One of the essential ingredients in selecting fabric for cooling garments is high heat transfer coefficient. In this study five different type of knitting fabrics with similar woven pattern were selected. The fabri…

Nano particles of Fe 3 O 4 with the range of 6.9 and 14.2 nm. By using chemical coprecipitation method. Particle size effect according to magnetic properties were investigated together with the constant reaction and crystallization temperature. According to calculations peaks were indexed as cubic Fe 3 O 4 for all sam…
Structural data of CorA Mg(2+) channels show that the five Gly-Met-Asn (GMN) motifs at the periplasmic loop of the pentamer structure form a molecular scaffold serving as a selectivity filter. Unfortunately, knowledge about the cation selectivity of Mg(2+) channels remains limited. Since Mg(2+) in aqueous solution has…
A serious limitation of the all-in-vacuum diffractometer reported by Straasø, Dippel, Becker & Als-Nielsen [ J. Synchrotron Rad. (2014), 21 , 119–126] has so far been the inability to cool samples to near-cryogenic temperatures during measurement. The problem is solved by placing the sample in a jet of helium gas…
Role of Yarn Tension in Weaving deals exclusively with the various aspects of tension of warp and weft yarns during weaving and its preparatory processes. The ten chapters contain numerous illustrations so that the text can be understood easily and clearly. This book will be useful to students, mill personnel, and res…
Nanotoxicity has become of increasing concern since the rapid development of metal nanoparticles (NPs). Aquatic nanotoxicity depends on crucial qualitative and quantitative properties of nanomaterials that induce adverse effects on subcellular, tissue, and organ level. The dose-response effects of size-dependent metal…
The solubility of (S)-3-(aminomethyl)-5-methylhexanoic acid in both 2-propanol and water and methanol and water mixtures, as well as in pure solvents, is reported across the temperature range of 283.15–338.15 K, as determined gravimetrically under atmospheric conditions. The experimental data is correlated using the e…
Abstract We investigated novel organic/inorganic hybrid thermoelectric materials prepared using several metal-polymer complexes, binders (insulating polymers), and inorganic semiconductor nanomaterials. It was found that the three-component hybrid thermoelectric materials, which consisted of nanodispersed poly(nickel…
Metallodielectric nanostructured core-shell-shell particles are particularly desirable for enabling novel types of optical components, including narrow-band absorbers, narrow-band photodetectors, and thermal emitters, as well as new types of sensors and catalysts. Here, we present a facile approach for the preparation…
The degradation of air quality by the release of volatile organic compounds (VOCs) into the air particularly harms human health and our environment. [...]
The aim of this work was to provide a comprehensive insight concerning coated films which might be used for first mirrors in ITER. The influence of the mirror crystallite size has been addressed as well as the coating techniques to provide nanocrystalline films. Tests of coated mirrors both in laboratories and in toka…
The single-electron oxidative dimerization of basket-handle porphyrins (BHPs) with different coordinated metal ions [Cu(II), Ni(II), Pd(II), Zn(II)] yielded directly meso-meso linked dimers in excellent yields. The synthetic protocol is suited for coupling substrates with different meso-substituents (H, Br, aryl, alky…
In this work, native emulsion polymerization styrene butadiene rubber (SBR) were first grafted by vinyltriethoxysilane (VTES) to SBR‐ g ‐VTES (VTES grafted SBR), second, the SBR‐ g ‐VTES were modified by different amount of TEOS (tetraethoxysilane) using in situ sol‐gel method, at the last, the extra silica was added…
