Mackinawite is a naturally occurring layer-type FeS mineral important in biogeochemical cycles and, more recently, in the development of microbial fuel cells. Conflicting results have been published as to the magnetic properties of this mineral, with M\"ossbauer spectroscopy indicating no magnetic ordering down to 4.2…
Various intrinsically colored and luminescent silks are produced in vivo through the direct uptake of dyes into silkworms. A better understanding is established to select and design functional materials for effective uptake into silk fibroin by controlling structure-dependent hydrophobicity and self-assembly capabilit…
Source and drain functionalization with a light-responsive azobenzene-based self-assembled monolayer (SAM) is used to modulate the charge injection at the Au electrode–semiconductor interface of an organic field-effect transistor (OFET). This photochromic bistable SAM mediates the injection through the variation of th…
Abstract Micro‐solid oxide fuel cells ( μ ‐SOFCs) are fabricated on nanoporous anodic aluminum oxide (AAO) templates with a cell structure composed of a 600‐nm‐thick AAO free‐standing membrane embedded on a Si substrate, sputter‐deposited Pt electrodes (cathode and anode) and an yttria‐stabilized zirconia (YSZ) electr…
Lanthanide-doped upconversion nanocrystals which can convert near-infrared lights to visible lights have attracted growing interest because of their great potentials in biomedical engineering. However, it remains a grand challenge to maneuver the intensity ratio between different emission lines and enable tunable upco…
Remarkable progress has been made to date in the discovery of material binding peptides and their utilization in nanotechnology, which has brought new challenges and opportunities. Nowadays phage display is a versatile tool, important for the selection of ligands for proteins and peptides. This combinatorial approach…
The assembly of colloidal nanocrystals (NCs) into superstructures with long-range translational and orientational order is sensitive to the molecular interactions between ligands bound to the NC surface. We illustrate how ligand coverage on colloidal PbS NCs can be exploited as a tunable parameter to direct the self-a…
Half-Heuslers would be important thermoelectric materials due to their high temperature stability and abundance if their dimensionless thermoelectric figure of merit (ZT) could be made high enough. The highest peak ZT of a p-type half-Heusler has been so far reported about 0.5 due to the high thermal conductivity. Thr…
In the era of nanoscience where all the devices and technologies are going to smaller and smaller in size with improved properties; catalysis is an important field of application. In this review article we are trying to summarize data reported in literature for application of nano sized catalyst in our daily life whic…
Abstract Carbide‐derived carbons (CDCs) are a large family of carbon materials derived from carbide precursors that are transformed into pure carbon via physical (e.g., thermal decomposition) or chemical (e.g., halogenation) processes. Structurally, CDC ranges from amorphous carbon to graphite, carbon nanotubes or gra…
We demonstrate the design and fabrication of a novel flexible nanoarchitecture by facile coating ultrathin (several nanometers thick) films of MnO2 to highly electrical conductive Zn2SnO4 (ZTO) nanowires grown radially on carbon microfibers (CMFs) to achieve high specific capacitance, high-energy density, high-power d…
Abstract In this work, a novel method to simultaneously measure in situ swelling and sorption of gases and supercritical fluids in polymers in a commercially available apparatus is proposed. A gravimetric approach reported recently is applied to measure sorption whereas swelling is determined in situ by direct visuali…
Single crystals of silver(I) polyphosphate(V), AgPO(3), were prepared via a phospho-ric acid melt method using a solution of Ag(3)PO(4) in H(3)PO(4). In comparison with the previous study based on single-crystal Weissenberg photographs [Jost (1961 ▶). Acta Cryst. 14, 779-784], the results were mainly confirmed, but wi…
The influence of spindle speed on yarn quality was investigated. The yarn properties such as strength, breaking extension, imperfections and hairiness were studied. The strength of 39 tex 10/90 flax/cotton blended yarn was seen to have a lower value than the 59 tex equivalent yarn as spindle speed increased. But the b…
Abstract New polyhydrazides and poly(amidehydrazide)s bearing redox‐active carbazole and triphenylamine units were prepared. The resulting poly(1,3,4‐oxdiazole)s and poly(amide‐1,3,4‐oxadiazole)s had high glass‐transition temperatures (288–330 °C) and high thermal stability. The dilute solutions of all the hydrazide a…
We studied the magnetic coupling between magnetic atoms at the O-terminated ZnO(0001̅) surface using first-principles total energy calculations. It was found that the substitutional Co and Mn in the O-terminated ZnO(0001̅) surface tend to occupy the outermost cation layer. Different from the magnetic behaviors between…
The refining operation of cellulose fibrous suspensions results in fibrillation, hydration, and shortening of fibers. To characterize the viscous behavior of such a suspension during processing, rheological properties of bleached softwood fibers are studied by considering a semi-industrial disk refiner as a parallel p…
We present the results of magnetization relaxation measurements across the ferromagnetic to antiferromagnetic transition in Fe(0.955)Ni(0.045)Rh. The transition from the high temperature ferromagnetic phase to the low temperature antiferromagnetic phase seems to be arrested by increasing the applied magnetic field. Th…
OBJECTIVES: Pegylated liposome formulations of vinorelbine with prolonged circulation half-life (t½) are desirable. However, DSPE-PEG could affect vinorelbine loading into vesicles due to electrostatic interactions. To resolve this problem, chol-PEG was used to prepare pegylated liposomal vinorelbine and the factors a…
The key problem in thermal modelling of a quantum cascade laser (QCL) is determining the thermal conductivity λ of its active region. The parameter is highly anisotropic. In particular, the cross-plane value λ ⊥ is significantly reduced, which may be attributed to the presence of a large number of interfaces between e…
