Background: In the recent years, polymeric nanofibers have gained lots of attention in the area of drug delivery applications. Owing to its simplicity, ease of composition method and high drug loading capacity, it provides various benefits for the therapeutic applications. Nanofibers are useful for the delivery of antibiotics, anticancer drugs, analgesic's agents and various proteins for drug delivery applications. Electrospinning meth Read More

Background: Pharmacokinetic issues and poor solubility in water are the most important concerns of numerous recently developed chemical entities. Objective: The drugs which are poorly soluble in water demonstrate numerous formulating troubles in conventional dosage forms and the low bio-availability is the critical problem linked with it. A nanosponge is an emerging technology which can overcome these problems a Read More

Background: In this study, the ultracapacitor has been fabricated based on the BaTiO3/ PEDOT: PSS separator film and polyvinyl alcohol (PVA) electrolyte. On the paper-substrate was coated a film of the graphite nanoparticles (GNPs) as an electrode. The GNPs and surface morphology of the separator, electrolyte and electrode have been characterized using transmission electron microscopy (TEM) and scanning electron Read More

Background: Amphoteric membranes such as Titania Pillared Clay (TiPILC) membranes exhibit different charges at different pH ranges, subsequently show efficient separation for cationic and anionic organic pollutants in wastewater based on solution pH. The structural properties of such membranes determine their permeability and selectivity to a large extent. The present work is initiated to explore the possibility of Read More

Background: Salicylic acid (SA), used as an important component in a lot of skin care products, has been reported widely. And because of large specific surface area, high porosity and good surfactivity, electrospun drug-loaded nanofibers have been widely used in various applications including wound dressing, tissue engineering and drug release. Particularly, the electrospun SA loaded porous nanofibers could be fabric Read More

Background: The TPP technology is a “nano-optics” 3D printing technology that develops in recent years. Compared with the traditional 3D printing technology, the TPP-3DP technique that takes near-infrared light femtosecond pulse laser as the light source can break through the limitation of optical diffraction and manufacture nanoscale 3D structures in arbitrary shapes with high resolution. Method: The research develops a cl Read More

Background: Because line width has been close to atom size, for semiconductor industry, except for achieving the target of line width, the cost will be more important. The mask-less laser interference lithography (LIL) technique lowers the cost makes it standing out in the market of lithographic equipment of the excessive cost in the semiconductor industry. Method: The Keywords of patent retrieval with the theme of LIL are base Read More

Background: This paper examines nanotechnology patents in Mexico to gain some insights into: a) the growth of patents over the last twenty years; b) the distribution of assignee patents between private and public institutions; b) the economic sectors engaged in nanotechnology R and, c) whether R is oriented to basic research or more applied science and engineering. Method: The present research employs the DG concor Read More
