With first-principle DFT calculations, the catalytic activity of heteroatom-doped carbon nanostructures in oxygen reduction reaction is investigated by exploring the active site of B-doped, N-doped and (B, N)-codoped and analyzing the kinetic pathways of oxygen reduction with the participation of protons. It is found…
The behavior of WO3 photoanodes has been investigated in contact with a combination of four anions (Cl−, CH3SO3−, HSO4−, and ClO4−) and three solvents (water, acetonitrile, and propylene carbonate), to elucidate the role of the semiconductor surface, the electrolyte, and redox kinetics on the current density vs. poten…
In2O3-In2S3 core-shell nanostructures were prepared via a simple hydrothermal process at low temperatures. Ultraviolet photoelectron spectroscopy (UPS) shows that the In2O3-In2S3 nanorod is an inverted type I nanostructure. The energy potential in this structure would drive both the photo-generated holes and electrons…
MicroRNAs are small non-coding RNAs that suppress gene expression through target mRNA degradation or translation repression. Recent studies suggest that miRNA plays an important role in multiple physiological and pathological processes in the nervous system. In this review article, we described what is currently known…
The inner structure of W18O49 mesocrystals was observed by electron microscopy with the help of ultramicrotomy and focused ion beam techniques. The results showed that these mesocrystals contain irregular mesopores formed through partial fusion of self-assembled nanowires, and consequently have long-range structural o…
This communication describes the mild and quick construction of tough nanocomposite hydrogels via a horseradish peroxidase-mediated radical polymerization for effectively immobilizing enzymes to attain high catalytic performance in various solvents.
Most high-performance organic solar cells involve bulk-heterojunctions in order to increase the active donor-acceptor interface area. The power conversion efficiency depends critically on the nano-morphology of the blend and the interface. Spectroscopy of the sub-bandgap region, i.e., below the bulk absorption of the…
Soft materials capable of both planar and flexural–torsional responses could enable the development of soft robotic elements that emulate the dexterity and functionality of a multitude of creatures in the animal kingdom. Here, we examine the response of azobenzene-functionalized liquid crystal polymer networks (azo-LC…
Garnet-type Li5La3Nb2O12, among several other Li-stuffed garnet compounds, is known to be unstable under moisture and undergoes H+/Li+ ion-exchange at room temperature. While there have been reports on proton-exchange in water, the transport of the protons in the garnet structure is yet to be characterized by electric…
The role of encapsulating polymers in nanocrystalline Mg air stability and hydrogen storage density was studied for a series of composites varying in both % Mg and polymer identity. In these materials, the Mg nanocrystals are completely dependent on the polymer for air stability. Remarkably, both air stability and hyd…
INTRODUCTION: The microwave oven has been used quite often for tissue processing, but there are very few studies describing its use in decalcification of bone or teeth. In this study we have attempted to decalcify bone and teeth using a microwave oven and compare the process and results with conventional decalcificati…
This paper presents a novel strategy to prepare Cu3(BTC)2@SiO2 core-shell nanoparticles in the size range of 200-400 nm using a new one-pot strategy under ultrasonic irradiation at room temperature. In this approach, the silica shell thickness could be finely tuned in the size range of 12-60 nm for various reaction ti…
Two algorithms that combine Brownian dynamics (BD) simulations with mean-field partial differential equations (PDEs) are presented. This PDE-assisted Brownian dynamics (PBD) methodology provides exact particle tracking data in parts of the domain, whilst making use of a mean-field reaction-diffusion PDE description el…
The SCSC transformation of a 1D polymer [Cd(1,3-bdc)(4-spy)2]n produced a 2D polymer [Cd(1,3-bdc)(4-spy)(HT-ppcb)0.5]n through the [2+2] photodimerization reaction. Hydrothermal reactions of HT-ppcb with CdCl2, 1,3-H2bdc and H2O2 afforded another 2D polymer {[Cd(H2O)(1,3-bdc)(bpbpf)]·H2O}n in which HT-ppcb underwent i…
Porous anatase TiO(2) microspheres composed of {010}-faceted nanobelts were synthesized through simple thermal treatment of a titanium glycerolate precursor. The as-prepared TiO(2) nanomaterial was shown to serve as an efficient photocatalyst for H(2) evolution, and its activity was more than twice that of the benchma…
Eight three-dimensional lanthanide-organic frameworks: [Ln(BPDC)1.5(DMF)(H2O)2]·2H2O (Ln = Eu (1), Gd (2), Tb (3), Dy (4); BPDC = 4,4'-dicarboxylate-2,2'-dipyridine anion), [Ln(BPDC)(DMF)2(NO3)] (Ln = Eu (5), Gd (6), Tb (7), Dy (8)) were fabricated and structurally characterized. Compounds 1-4 are isostructural, belon…
With the ever-increasing environmentally-driven demand for technologically advanced structural materials, geopolymer cement is fast becoming a viable alternative to traditional cements due to its proven engineering characteristics and the reduction in CO2 emitted during manufacturing (as much as 80% less CO2 emitted i…
The phase behaviour of mCherry-b-PNIPAM (mChP) block copolymers with four different PNIPAM coil fractions is investigated in concentrated aqueous solution as a function of both concentration and temperature, demonstrating both order–order transitions (OOTs) and order–disorder transitions (ODTs) in globular protein–pol…
We give an overview on experimental studies performed in the last 25 years on heavy-fermion systems in a high magnetic field. The properties of field-induced magnetic transitions in heavy-fermion materials close to a quantum antiferromagnetic-to-paramagnetic instability are presented. Effects of a high magnetic field…
Wide spectral responsive 3D hierarchical CdS/α-Fe2O3 heterojunction nanocomposites were synthesized through a facile chemical bath method under mild conditions, and used for the reduction of Cr(VI) into Cr(III) under visible light irradiation. The effects of CdS/α-Fe2O3 molar ratio in the nanocomposites on the crystal…
