An alginate hydrogel binder is prepared through the cross linking effect of Na alginate with Ca(2+) ions, which leads to a remarkable improvement in the electrochemical performance of the Si/C anode of a Li-ion battery.
An organic–inorganic based surface film was formed on a 5 V-class LiNi 0.5 Mn 1.5 O 4 cathode by tris(trimethylsilyl)phosphite (TMSP). This surface-modified cathode exhibited significantly improved electrochemical properties in terms of cycling stability and rate capability.
A magnetic porous carbon composite which has been synthesized from MOF is used as a catalyst support to fabricate Au and Pd NP based nanocatalysts.
A theoretical analysis of different device concepts for solar hydrogen production, demonstrating the close similarities between photoelectrochemical cells and PV-electrolyzers.
ZnO nanoparticles are well known for their ability to generate Reactive Oxygen Species (ROS) which have a potential role in biological systems. ROS can enhance wound healing by improved cell adhesion and cell migration through growth factor mediated pathways. Here we report the fabrication of electrospun polycaprolact…
Triptycene-containing polyimide membranes with tunable fractional free volume promoting fast gas transport and selective separations.
We report two synthetic approaches to prepare a highly crystalline Zr(IV)-based metal-organic framework (MOF) containing open 2,2'-bipyridine (bpy) chelating sites. The resulting UiO-67-bpydc readily forms complexes with PdCl2 to produce a MOF that exhibits efficient and recyclable catalytic activity for the Suzuki-Mi…
The introduction of high dielectric constant ceramic nanoparticles into an insulating polymer is an important approach to prepare high dielectric constant nanocomposites for electric energy storage applications. A key to obtaining desirable properties is the homogeneous dispersion of the nanoparticles in the correspon…
Solution-processed organic and inorganic semiconductors offer a promising path towards low-cost mass production of solar cells. Among the various material systems, solution processing of multicomponent inorganic semiconductors offers considerable promise due to their excellent electronic properties and superior photo-…
Synergistic enhancement in photocatalytic degradation of α-Fe 2 O 3 –g-C 3 N 4 due to an increase in visible-light absorption efficiency and rapid photoinduced charge separation.
Administration of bone marrow-derived mesenchymal stem cells (MSCs) is an innovative approach for the treatment of a range of diseases that are not curable by current therapies including heart failure. A number of clinical trials have been completed and many others are ongoing; more than 2,000 patients worldwide have…
WO 3 /g-C 3 N 4 catalysts exhibit excellent photocatalytic performance for H 2 production from aqueous solution through the Z-scheme mechanism, which results in the efficient charge separation.
A novel 3D hybrid of layered MoS 2 /nitrogen-doped graphene nanosheet aerogels exhibits significantly enhanced catalytic activity for bio-electrochemical hydrogen evolution.
Flower-like hollow microspheres were synthesized on a large scale using a one-step hydrothermal route.
Cell culture is widely used by biochemists and cell/molecular biologists, but the fluctuating (and often elevated) levels of O 2 to which cells in culture are exposed can affect many of their properties. So can the low level of antioxidants found in some cell culture media. Reagents, especially "antioxidants," added t…
AgBr quantum dots (QDs) were decorated on the surface of Bi 2 WO 6 to form a novel AgBr/Bi 2 WO 6 heterojunction. The enhancement of catalytic efficiency of AgBr/Bi 2 WO 6 heterojunctions relative to pure Bi 2 WO 6 could be associated to differences in their lifetime as holes and electrons, and to valence and conducti…
A series of uniform ZnO nanospheres–reduced graphene oxide nanocomposites (ZnO–RGO NCs) with different weight addition ratios of RGO are successfully synthesized via a facile yet efficient method by intimately coating ZnO nanospheres (NSs) with RGO, which is afforded by electrostatic attraction between positively char…
Substitution reaction, as one of the most powerful and efficient chemical reactions, has been widely used in various syntheses, including those for the design and preparation of functional molecules or materials. In the past decade, a class of newly developed inorganic-organic hybrid materials, namely metal-organic ma…
Without Pt as cocatalyst, the photocatalytic hydrogen evolution activity of graphitic carbon nitride (g-C3N4) or even its composite is normally rather low (<1 μmol h(-1)). Exploring Pt-free cocatalysts to substitute precious Pt is of great importance in the photocatalytic field. In the present work, Ag2S-modified g-C3…
The performance of chemical sensors based on polymer nanocomposites with CNTs and graphene is revised, highlighting the role of the polymeric material.
