0.6Li2MnO3-0.4Li(Ni1/3Co1/3Mn1/3)O2 composite microspheres with dense structures are prepared by a two-step spray-drying process. Precursor powders with hollow and porous structures prepared by the spray-drying process are post-treated at a low temperature of 400 °C and then wet-milled to obtain a slurry with high stability. The slurry of the mixture of metal oxides is spray-dried to prepare pr...

There has been a growing interest in the design and development of polymeric microspheres as controlled release systems for drugs and antigens. Different types of polymers have been used to design biodegradable polymeric microparticles. Poly(lactic-co-glycolic) acid (PLGA) microspheres have been extensively investigated because of their biocompatibility and biodegradability. PLGA has been appro...

We demonstrate formation of long-lived cylindrical jets of a viscoelastic fluid using hydrodynamic focusing. A solution of polyacrylamide in water is driven coaxially with immiscible oil and subjected to strong extensional flow. At high flow rates, the aqueous phase forms jets that are 4-90 microm in diameter and several centimeters long. The liquid surfaces of these jets are then used as templ...

The recycling technology of photocatalyst powdery has hardly been mature in the photocatalytic oxidation so far. In this work, hollow TiO2 microspheres with an appropriate thickness are confined carbon (CMSs) to form TiO2@CMSs, which physically integrated carbon-fiber textile by van der Waals (vdW) interactions generate separable and recyclable TiO2@CMSs/carbon-fiber vdW heterostructures. Such ...

Intrinsically fluorescent carbon dots may form the basis for a safer and more accurate sensor technology digital counting in bioanalytical assays. This work presents simple inexpensive synthesis method producing embedded hollow silica particles. Hydrothermal treatment at low temperature (160 °C) of microporous particles presence urea citric acid results fluorescent, nanocomposites with surface ...
