Switchable and selective detection of Zn 2+ or Cd 2+ in living cells based on 3′-O-substituted arrangement of benzoxazole-derived fluorescent probes
Two benzoxazole-derived ESIPT fluorescent sensors and show highly selective detection of Zn(2+) and Cd(2+), respectively, in aqueous solution and living cells. The selectivity switching from Zn(2+) to Cd(2+) is attributed to the different binding mode which is dependent on the 3'-O-substituted arrangement.
Facile synthesis of three-dimensional porous carbon with high surface area by calcining metal–organic framework for lithium-ion batteries anode materials
3D porous carbon derived by the MOFs with an excellent performance of 1015 mA h g −1 after 100 cycles for LIBs.
Advances in Stabilizing ‘Layered-Layered’ xLi2MnO3·(1-x)LiMO2(M=Mn, Ni, Co) Electrodes with a Spinel Component
Composite electrode structures with layered and spinel components have been investigated to evaluate the possibility of arresting or suppressing the voltage fade observed on cycling high capacity, lithium- and manganese-rich 'layered-layered' xLi 2 MnO 3 •(1-x)LiMO 2 (M=Mn, Ni, Co) electrodes in lithium cells. Control…
Phase-selective hydrothermal synthesis of Cu 2 ZnSnS 4 nanocrystals: the effect of the sulphur precursor
CZTS thin films with uniform thickness and homogeneous composition for generation of a stable photocurrent were made using one-step hydrothermal synthesis.
Hierarchical porous nitrogen-rich carbon monoliths via ice-templating: high capacity and high-rate performance as lithium-ion battery anode materials
Ice-templating is utilized to prepare hierarchically porous carbon monolith with aligned macropores. N-doped and graphene-incorporated carbon composite can be easily produced, demonstrating a reversible capacity of about 300 mA h g −1 at a high current density of 10 A g −1 .
Thin film formation of Pd/reduced-graphene oxide and Pd nanoparticles at oil–water interface, suitable as effective catalyst for Suzuki–Miyaura reaction in water
A facile and efficient route was used to synthesise Pd nanoparticles by reduction of an organopalladium(II) complex, [PdCl2(cod)] (cod = cis,cis-1,5-cyclooctadiene), at the oil–water interface. Pd/reduced-graphene oxide and Pd free stabilizer nanoparticle thin films were characterized by Fourier transform infrared spe…
Synthesis and Growth Mechanism of Silver Nanowires through Different Mediated Agents (CuCl2 and NaCl) Polyol Process
Silver nanowires (AgNWs) have been synthesized by polyol process through different mediated agents (CuCl2 and NaCl). The presence of cations and anions (Cu(II), Na+, and Cl−) has been shown to have a strong impact on the shape of silver nanostructures. The field emission scanning electron microscopy (FESEM) and transm…
Spermidinium closo -dodecaborate-encapsulating liposomes as efficient boron delivery vehicles for neutron capture therapy
closo-Dodecaborate-encapsulating liposomes were developed as boron delivery vehicles for neutron capture therapy. The use of spermidinium as a counter cation of closo-dodecaborates was essential not only for the preparation of high boron content liposome solutions but also for efficient boron delivery to tumors.
Interaction forces between a spherical nanoparticle and a flat surface
Due to the breakdown of Derjaguin approximation at the nanoscale level apart from the neglect of the atomic discrete structure, the underestimated number density of atoms, and surface effects, the continuum Hamaker model does not hold to describe interactions between a spherical nanoparticle and a flat surface. In thi…
PHYSICOCHEMICAL PROPERTIES OF LECITHIN-BASED NANOEMULSIONS OBTAINED BY SPONTANEOUS EMULSIFICATION OR HIGH-PRESSURE HOMOGENIZATION
Nanoemulsions composed of a medium-chain triglyceride oil core stabilized by rapeseed or sunflower lecithins were prepared by spontaneous emulsification and high-pressure homogenization. These nanoemulsions are compared with formulations stabilized by egg lecithin. Nanoemulsions obtained by high-pressure homogenizatio…
Elucidating the oxide growth mechanism on platinum at the cathode in PEM fuel cells
Simulations of platinum oxidation in literature have yet to fully replicate an experimental cyclic voltammogram. In this manuscript a mechanism for platinum oxidation is proposed based upon the results of in operando X-ray absorption spectroscopy, where it was found that PtO2 is present at longer hold times. A new met…
Semiconductors with NIR driven upconversion performance for photocatalysis and photoelectrochemical water splitting
Infrared light (IR) occupies about 50% of solar irradiation, therefore, how to effectively utilize IR light is one of the main issues at present. Two major strategies which have been pursued for the development and utilization of near infrared (NIR) light in the field of photocatalysis and photoelectrochemical (PEC) w…
Data mining with molecular design rules identifies new class of dyes for dye-sensitised solar cells
A major deficit in suitable dyes is stifling progress in the dye-sensitised solar cell (DSC) industry. Materials discovery strategies have afforded numerous new dyes; yet, corresponding solution-based DSC device performance has little improved upon 11% efficiency, achieved using the N719 dye over two decades ago. Rese…

Etherification of glycerol with isobutene on sulfonated graphene: reaction and separation
Sulfonated graphene catalyzes the etherification of glycerol and isobutene with a high yield of multi-ethers and little deactivation after repeated use.
Cell Therapy with Human MSCs Isolated from the Umbilical Cord Wharton Jelly Associated to a PVA Membrane in the Treatment of Chronic Skin Wounds
The healing process of the skin is a dynamic procedure mediated through a complex feedback of growth factors secreted by a variety of cells types. Despite the most recent advances in wound healing management and surgical procedures, these techniques still fail up to 50%, so cellular therapies involving mesenchymal ste…
Morphological effect of gold nanoparticles on the adsorption of bovine serum albumin
Various properties of gold nanoparticles (GNPs) are found to play crucial roles in their biological activity. Among them, the morphology and surface chemistry are extremely important. This is because of differences in surface energies of various crystal facets arising from a large fraction of edges, corners and vertic…
The Alternative Route to Heme in the Methanogenic Archaeon Methanosarcina barkeri
In living organisms heme is formed from the common precursor uroporphyrinogen III by either one of two substantially different pathways. In contrast to eukaryotes and most bacteria which employ the so-called "classical" heme biosynthesis pathway, the archaea use an alternative route. In this pathway, heme is formed fr…
