Despite many of the studies being conducted, the electrospinning of poly (lactic acid) (PLA), dissolved in its common solvents, is difficult to be continuously processed for mass production. This is due to the polymer solution droplet drying. Besides, the poor stretching capability of the polymer solution limits the production of small diameter fibers. To address these issues, we have examined ...

Manganese oxides are of great interest as low cost and environmentally sound intercalation cathodes for rechargeable lithium batteries, but have suffered from limited capacity and instability upon cycling at the moderately high temperatures (50-70°C) encountered in many applications. Here, we show that LixAl0.05Mn0.95O2 of both the monoclinic and orthorhombic ordered rock salt structures exhibi...

The application of porous hydroxyapatite-collagen (HAp-Collagen) as a bone tissue engineering scaffold is hindered by two main problems: its high cost and low initial strength. As a native 3-dimenssional collagen framework, purified porcine acellular dermal matrix (PADM) has been successfully used as a skin tissue engineering scaffold. Here we report its application as a matrix for the preparat...

Previous work has suggested that ceria nanoparticles (CNPs) have regenerative antioxidant properties, which have motivated researchers to consider CNPs as therapeutic agents for treating a number of diseases, including cancer. Recent studies have shown CNPs to be toxic to cancer cells, to inhibit invasion and sensitize cancer cells to radiotherapy. In addition, several hydrophilic polymers have...

A facile and efficient method was developed to prepare the monodisperse biodegradable PEGylated pH and reduction dual-stimuli sensitive poly[methacrylic acid-co-poly(ethylene glycol) methyl ether methacrylate-co-N,N-bis(acryloyl)cystamine] (PMPB) nanohydrogels with dried particle size below 200 nm via one-step distillation precipitation polymerization as a drug delivery system (DDS) for the con...

Polymers have always been valuable excipients in conventional dosage forms, also have shown excellent performance into the parenteral arena, and are now capable of offering advanced and sophisticated functions such as controlled drug release and drug targeting. Advances in polymer science have led to the development of several novel drug delivery systems. Interpenetrating polymer networks (IPNs...

Tremendous applications of carbon-based nanomaterials need the individualization particles in liquid phase, preferably an aqueous solution. Currently, one main challenges is how to obtain highly monodispersed and high-quality colloidal solutions make it usable electronic devices without performing badly. In this study, carbon nanoparticles (i.e., fullerenes, nanotubes, graphene) were individual...

Scintillator is a critical component to detect high-energy particles or rays, which widely used in deep space exploration, security inspection, and nondestructive testing medical diagnosis, such as X-ray imaging computed tomography (CT). However, the wider application of traditional inorganic organic scintillators limited by complex operation process poor adaptability changeable environment, th...

Studies of storage and production hydrogen, which is an alternative to fossil fuels, have been intensified. Hydrogen from metal borohydrides via catalyst very attractive because its advantages, such as controlled production, high hydrogen content, nontoxicity, etc. In this study, the catalytic performances nanoporous nickel–chromium alloy nickel–vanadium catalysts prepared with magnetron sputte...

Phase change materials (PCMs), as latent thermal energy storage, have received plenty of attention in recent decades due to their excellent performance conservation. Inorganic hydrated salts many advantages over organic phase materials, such higher storage density, low cost, nontoxicity and nonflammability. This work presents a simple environmentally friendly method for the preparation microcap...
