Composite materials are used extensively in aerospace and more recently in automotive applications. Their high mechanical performances and good fatigue durability offer definite advantages compared to more traditional materials. However, in comparison with metal, damage mechanisms are complex and variability of the me…
Because of their potential application in the conversion of solar energy to chemical energy, the development of semiconductor photocatalysts that have high reactivity under visible light has received great attention. In the present work, we illustrate the design and fabrication of magnetically separable polymeric carb…
In recent years, the development of optical probes to analyse trace palladium ions (Pd(2+)) has attracted great attention because of the residual palladium released by catalytic converters or from various Pd-catalysed reactions. These residual palladium ions may cause potential health hazards. This review provides a b…
Carbon nitride (CN) nanosheets with a thickness of around 3 nm were prepared by pyrolysis of urea. Well-dispersed Pt nanoparticles of about 3 nm were pre-loaded on CN nanosheets as the co-catalyst by chemical reduction in ethylene glycol. The Pt/CN sample showed a H2 evolution rate of 45.1 μmol h−1 from an aqueous sol…
A detailed study on visible light photocatalytic degradation of methylene blue (MB) has been investigated in aqueous heterogeneous media containing hexagonal phase molybdenum oxide (h-MoO3) nanocrystals (NCs) which was identified as a new material for visible light driven photocatalysis. A simple and template-free sol…
The purpose of the present study was to present a multi-delay multi-parametric pseudo-continuous arterial spin labeling (pCASL) protocol with background suppressed 3D GRASE (gradient and spin echo) readout for perfusion imaging in acute ischemic stroke. PCASL data at 4 post-labeling delay times (PLD = 1.5, 2, 2.5, 3 s…
The fabrication characteristics and mechanical behaviour of Al-Mg-Si alloy matrix composites reinforced with alumina (Al2O3) and rice husk ash (RHA, an agro-waste) was investigated. This was aimed at assessing the viability of developing high performance Al matrix composites at reduced cost. Al2O3 particulates added w…
This review on polymorphism is a personal, non-comprehensive view on the field of polymorphism – a term which is often misused. Indeed, the discussion about polymorphism and related terms is still ongoing in the area of crystal engineering. This is why we felt it timely to look into the historical development of its d…
Na-stabilized Li1.2−xNax[Co0.13Ni0.13Mn0.54]O2 is synthesized by introducing larger Na ions into the Li slabs of the layered material through a simple polymer-pyrolysis method. The structural and morphological characterization reveals that the Na doping leads to a more ordered structure with regular cubic morphology a…
BACKGROUND: Mutation of a single amino acid residue can cause changes in a protein, which could then lead to a loss of protein function. Predicting the protein stability changes can provide several possible candidates for the novel protein designing. Although many prediction tools are available, the conflicting predic…
CO2 uptake in zirconium MOF UiO-66 almost doubles with post-synthetic exchange of Zr by Ti. This was due to smaller pore size and higher adsorption enthalpy, with good complementarity between experiment and simulation. Furthermore, the full effect is obtained with ~50% Ti loading, precluding the need to fully substitu…
Porous organic frameworks (POFs) as an important subclass of nanoporous materials are of great interest in materials science. In recent years, the discovery and creation of POFs with excellent properties for advanced applications have attracted much attention and intensive efforts have been contributed to this field.…
Within the past few years, chitosan-based drug delivery vehicles have become some of the most attractive to be studied. In contrast to all other polysaccharides, chitosan has demonstrated its unique characteristics for drug delivery platforms, including its active primary amino groups for chemical modification, simple…
Highly efficient photocatalysts for visible light-induced O2 generation are synthesized via an electrostatically derived self-assembly of Zn–Cr-LDH 2D nanoplates with graphene 2D nanosheets. In the obtained nanohybrids, the positively charged Zn–Cr-LDH nanoplates are immobilized on the surface of negatively charged gr…
A luminescent two-dimensional (2D) coordination polymer is demonstrated to be a selective sensing material for the straightforward detection of nitrobenzene via a redox fluorescence quenching mechanism.
In this study we demonstrate that self-doping and surface plasmon resonance could endow a wide-band-gap ternary semiconductor BiOCl with remarkable visible light driven photocatalytic activity on the degradation of organic pollutants and photocurrent generation properties. The self-doped BiOCl with plasmonic silver mo…
A three-dimensional graphene-based hierarchically porous carbon (3DGHPC) has been prepared by a dual-template strategy and explored as the electrode for capacitive deionization (CDI). The texture analyses indicate that the incorporation of porous carbon into the three-dimensional graphene (3DG) has constructed a hiera…
Mesoporous NiO nanosheet networks with a thickness of more than 5 μm were fabricated on Ni foam for application as an electrode in Li ion batteries. Benefiting from the favorable macro/meso-porous structures as well as the great loading of the synthesized NiO, the electrode exhibits high capacity and excellent rate ca…
Rice-shaped Ti(3+) self-doped TiO(2-x) nanoparticles were synthesized by mild hydrothermal treatment of TiH(2) in H(2)O(2) aqueous solution. The structure, crystallinity, morphology, and other properties of the as-prepared samples were characterized by X-ray diffraction, transmission electron microscopy, high-resoluti…
A synthetic route to low-density porous Ni-doped Co3O4 nanomaterials that show stable and superior electrocatalytic activity for O2 evolution reaction is reported. The materials are prepared via thermal treatment of "pre-synthesized" metal ions-embedded graphitic C3N4-based polymers.
