Abstract Nanoparticles (NP) have specific catalytic properties, which are influenced by parameters like their size, shape, or composition. Bimetallic NPs, composed of two metal elements can show an improved catalytic activity compared to the monometallic NPs. We, herein, report on the selective aerobic oxidation of be…
FlgG is a bacterial flagellar rod protein and constructs the distal rod connecting to the hook. FlgG of Salmonella enterica serovar Typhimurium is a 260-amino-acid protein composed of a folded core region and N- and C-terminal regions that are unfolded in solution. A core fragment of FlgG (FlgG47-227) was expressed, p…
To examine the effects of the inherent heterogeneity in graphitic hexagonal pores on Kr adsorption in the monolayer (ML) regime, we measured the powder X-ray diffraction (XRD) patterns of Kr adsorbed on the walls of the graphitic hexagonal pores, as well as the flat surfaces of graphitized carbon black, as a function…
S i 3 N 4 – S i C composite ceramics used for volumetric receivers were fabricated by pressureless sintering of micrometer S i C , S i 3 N 4 , andalusite, and other minor additions powders. Mechanical, thermal expansion, thermal conductivity, and thermal shock resistance properties were tested at different sintering t…
In this paper, micrometers long and 20–100 nm diameter SiC nanowires had been synthesized in the short cut fiber toughened SiC composites (Csf/SiC) by annealing treatment. The present work demonstrated that it was possible to fabricate the in situ SiC nanowires toughened Csf/SiC composites by annealed treatment. The “…
Aluminum oxynitride spinel ( AlON ) powders were synthesized by aluminothermic reaction in a reducing N 2 ‐ CO atmosphere. Low cost and easily available aluminum and γ‐ Al 2 O 3 alumina micrometer‐sized powders were employed as starting materials. Mixed powders consisting of 75 wt% Al and 25 wt% Al 2 O 3 were milled t…
To explore the feasibility of constructing a functional biomaterial complex with regenerated silk fibroin membrane and immortalized chondrocytes in vivo. Rat auricular chondrocytes (RACs) were transfected with the lentivirus vector pGC-FU-hTERT-3FLAG or pGC-FU-GFP-3FLAG, encoding the human telomerase reverse transcrip…
The effects of graphene oxide (GO) on the yield stress‐pH of α‐Al 2 O 3 (alumina) suspensions were investigated. For micron‐sized platelet alumina suspensions, micron‐sized GO additive increased the maximum yield stress by as much as six‐folds. This was attributed to GO‐mediated bridging interactions between the plate…
Moderne Weltwunder: Nanostrukturierte Filme aus plasmonischen Pyramiden-Arrays (siehe Bild) wurden durch einfaches Aufstempeln von vorgefertigten homogenen Nanokolloiden erzeugt. Die Materialien wirken als effiziente optische Verstärker und können für die Konstruktion quantitativer, billiger, tragbarer, ultraempfindli…
Two dynamic transitions or crossovers, one at a low temperature (T${}^{*}$ \ensuremath{\approx} 1006 K) and the other at a high temperature (T${}^{0}$ \ensuremath{\approx} 1384 K), are shown to emerge in supercooled liquid silicon using molecular dynamics simulations. The high-temperature transition (T${}^{0}$) marks…
Hopping dynamics in glass has been known for quite a long time. In contrast, hopping dynamics in smectic-A (SmA) and hexatic smectic-B (HexB) liquid crystals (LC) has been observed only recently. The hopping in SmA phase occurs among the smectic layers (one-dimensionally), while hopping in HexB phase occurs inside the…
This work used 2‐hydroxypropyl‐3‐piperazinylquinolinecarboxylic acid methacrylate (HPQM) or silver‐substituted zeolite (SSZ) as antibacterial agents for natural rubber (NR) compounds vulcanized by conventional vulcanization (CV), semi‐efficient vulcanization, and efficient vulcanization (EV) systems. The cure behavior…
The possibility of controlling the optical transition probability between neighboring silicon nanoclusters (Si-NCs) constitutes nowadays an attractive prospect in nanophotonics and photovoltaics. In this work, by means of theoretical ab initio calculations, we investigate the effect of strain on the optoelectronic pro…
Computational methods (DFT at the B3LYP, PBE0 and m06 levels, MO fragments decomposition, and the broken symmetry approach) have been used to evaluate the influence of the bridging ligand (BL) on the extent of electron delocalization in coordination polymers based on diruthenium tetracarboxylates. The efficiency of th…
ZnS thin films with nano-rod and chiral sculptured structures of different thicknesses were deposited on glass substrates. Nano-structure of the films was obtained, using field emission scanning electron microscopy (FESEM). Their optical properties were measured by spectrophotometry in the spectral range of 350–1000 n…
Well-defined Au-SiO(2)-CdTe composite nanoparticles were synthesized via a multistep chemical approach in water solution to gain insight into the interaction between metal and semiconductor nanostructures. Photoluminescence measurement reveals that the fluorescence of CdTe quantum dots (QDs) in this composite with opt…
Magnetization modulation by ferroelectric polarization switching is reported for the ferromagnetic-ferroelectric EuO/BaTiO3 heterostructure. The value of the magnetization critical exponent β is consistent with the expected Heisenberg-like ferromagnetism of EuO and reported Curie temperature. The critical exponent is…
In this study, we report the light-emitting assistance effect of perylene on a polymer electrochemiluminescence (ECL) device using poly(3-octylthiophene-2,5-diyl) (P3OT). An ECL device is a liquid type self-luminous device with a simple structure, and can be fabricated by a relatively easy procedure. Significant impro…
We perform in-plane optical spectroscopy measurement on (00l) FeSe thin film grown on SrTiO${}_{3}$ substrate by the pulsed laser deposition method. The study indicates that the low-frequency conductivity consists of two Drude components: a broad one which takes up most of the spectral weight and a very narrow one rou…
This work demonstrates the anomalous crystal growth of isotactic polystyrene (iPS) in nanorod arrays with different rod sizes. At the bottom of the nanorods, the crystals in bulk film grow into nanorods along either the [110] or [100] direction parallel to the rod axis. On the top side of the nanorods, the polymer exh…
