-symmetric molecule. Most importantly, the excellent tunability of these novel CPL materials, which benefits from achiral molecular building blocks as well as the nature of supramolecular gels, has been investigated. Thus, the CPL intensity of these supramolecular gels is easily enhanced by mechanical stirring or dopi…
H 3 PO 4 promoted the decomposition of some species to form CO 2 and reacted with PBTRHR to form PH 3 .
Single-phase cool white-light emitting BaNb2O6:Dy(3+) phosphors have been synthesized via a conventional solid-state reaction method and characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM) observations and spectrofluorophotometric measurements. XRD and Rietveld structural refinement studies…
Epoxy polymers represent a recently emerged class of thermoset shape memory polymers with superior thermo-mechanical endurance and excellent processability.
The redox properties of metallic nanoparticles are discussed, in particular the relationships between excess charge, size and the Fermi level of the electrons. The redox potentials are derived using simple electrostatic models to provide a straightforward understanding of the basic phenomena. The different techniques…
This review discusses about the crystal structure, chemical bonding, and the electronic band structure of tetrahedrite materials. Also, this review outlines the effect of different doping elements on the thermoelectric properties of tetrahedrite materials.
Blends of poly(lactic acid) (PLA) and poly(3-hydroxybutyrate) (PHB) plasticized with a lactic acid oligomer (OLA) added at three different concentrations (15, 20 and 30 wt% by weight), were prepared by an optimized extrusion process to improve the processability and mechanical properties of these biopolymers for flexi…
MnO 2 with α-, β- and δ-type structures were controllably synthesized. The electrochemical properties of the supercapacitors based on different types of MnO 2 electrodes were investigated in detail.
The focus on surface lattice strain in nanostructures as a fundamental research topic has gained momentum in recent years as scientists investigated its significant impact on the surface electronic structure and catalytic properties of nanomaterials. Researchers have begun to tell a more complete story of catalysis fr…
Raman spectroscopy has enabled researchers to map the specific chemical makeup of surfaces, solutions, and even cells. However, the inherent insensitivity of the technique makes it difficult to use and statistically complicated. When Raman active molecules are near gold or silver nanoparticles, the Raman intensity is…
The ultimate goal of making atomically thin electronic devices stimulates intensive research on layered materials, in particular the group-VI transition metal dichalcogenides (TMDs). Atomically thin group-VI TMD crystals with a 2H stacking order emerging as a family of intrinsic 2-dimensional (2D) semiconductors with…
Owing to the electron donor-acceptor properties of GO, the active sites ([triple bond, length as m-dash]Fe(2+)) of Fe3O4 are not oxidised ([triple bond, length as m-dash]Fe(3+)) in the heterogeneous Fenton-like reaction. GO plays a sacrificial role via the oxidation of (C[double bond, length as m-dash]C) carbon domain…
Common toxicity patterns emerge across toxicity tests with species from different trophic levels.
Natural fibres will take a major role in the emerging "green" economy based on energy efficiency, the use of renewable materials in polymer products, industrial processes that reduce carbon emissions and recyclable materials that minimize waste. Natural fibres are a kind of renewable resources, which have been renewed…
A green approach was developed for the preparation of fluorescent carbon dots (CDs) by using lychee seeds as precursors, and the CDs were employed as fluorescence probes for the detection of methylene blue and imaging in living cells.
This review presents recent studies on low-temperature NH 3 -SCR catalysts, particularly Mn-based oxides, V 2 O 5 /AC, and Cu-based small pore zeolites.
High conversion efficiency is demonstrated at a relatively small temperature difference for a MgAgSb-based single thermoelectric leg with hot-pressed contacts.
Copper doped ZnO nanostructures have been synthesized by a facile wet chemical method. Structural properties of as-synthesized nanomaterials have been studied by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) and transmission electron microscopy (TEM) with energy dispersive X-ray spectros…
Transfer of energy occurs endlessly in our universe by means of radiation. Compared to energy transfer (ET) in free space, in solid state materials the transfer of energy occurs in a rather confined manner, which is usually mediated by real or virtual particles, including not only photons, but also electrons, phonons,…
Highly dense Cu 2−x S bulks, fabricated by a melt-solidification technique, show high thermoelectric performance with zT of ∼1.9 at 970 K.
