Au-Pd Separation Enhances Bimetallic Catalysis of Alcohol Oxidation

In oxidation reactions catalysed by supported metal nanoparticles with oxygen as the terminal oxidant, the rate of the oxygen reduction can be a limiting factor. This is exemplified by the oxidative dehydrogenation of alcohols, an important class of reactions with modern commercial applications1–3. Supported gold nanoparticles are highly active for the dehydrogenation of the alcohol… Continue reading Au-Pd Separation Enhances Bimetallic Catalysis of Alcohol Oxidation

New fluorescent nanovesicles for intracellular biomarker detection

Schematic representation of the DNA-grafted QS nanovesicles. QSs loaded with an organic fluorophore (i.e., donor) are prepared, and a fluorescent 5′-end cholesteryl-triethylene glycol (TEG) modified DNA probe (i.e., F-miRNA probe) is added to the colloidal system in order to self-assemble into the membrane. The incorporation of the fluorescent amphiphilic DNA probe within the nanovesicle membrane… Continue reading New fluorescent nanovesicles for intracellular biomarker detection

High energy density of BaTiO3@TiO2 nanosheet/polymer composites via ping-pong-like electron area scattering and interface engineering

Microstructures of the nanofillers and dielectric film Figure 1a shows a schematic for the preparation of BT@TO ns hybrids via a filtration-stacking and heat-treatment process. The BT@TO ns hybrid consists of two or more thin, large-area TO nss acting as the host/covering layer and several BT nps acting as the core particles. The stacked hybrid… Continue reading High energy density of BaTiO3@TiO2 nanosheet/polymer composites via ping-pong-like electron area scattering and interface engineering

Non-conventional superconductivity in magnetic In and Sn nanoparticles

Ferromagnetic spin polarization The isothermal magnetization curves M(Ha) of the NP assemblies reveal a rapid increase with increasing Ha in the low Ha regime, reaching saturation at a higher Ha. Figure 1b shows representative M(Ha) curves of 7 nm In-A (open triangles) and 7 nm Sn-A (solid circles) NP assemblies taken at 300 K. The M(Ha) can be described… Continue reading Non-conventional superconductivity in magnetic In and Sn nanoparticles
