A novel lamellar-structured Co/Co(OH)2 nanocomposite was synthesized with a room-temperature solution-phase reduction method. A possible reaction mechanism and shape evolutionary process for the Co/Co(OH)2 nanocomposite were supposed. The Co/Co(OH)2 nanocomposite shows a ferromagnetic behavior. Congo red (CR) was used to evaluate the Co/Co(OH)2 nanocomposite wastewater treatment capability. It ...

conclusions this study showed that compared to standard drug treatment, treatment with hydrogel containing peptide had substantial antibacterial effects on s. aureus wound infections in mice. results the highest and lowest numbers of wounds were observed on day 2 in the negative and positive control groups, respectively. during the 8-day period, the positive control and hydrogel containing pept...

Chitosan/multiwalled carbon nanotube nanocomposite has been successfully synthesized by the chemical method. The prepared nanocomposite was characterized using XRD, FTIR and HRTEM. The XRD pattern of the nanocomposite shows the presence of planes corresponding to both chitosan and MWCNT and the absence of impurity phases. The semi-crystalline nature of chitosan is also evident from the obtained...

The present work reports development of a magnetic hydrogel adsorbent material based on the polysaccharide, gum acacia. This graft copolymer nanocomposite acacia and poly(3-chloro-2-hydroxypropylmethacrylate) has been made using microwave assisted technique. Magnetite nanoparticles have generated by in-situ method trapped in network structure. parent hybrid were evaluated as adsorbents for sequ...

We develop a facile, effective and filter free infiltration method to fabricate high performance, freestanding and superthin epoxy nanocomposite films with directly synthesized Sing-Walled Carbon Nanotubes (SWNTs) film as reinforcement skeleton. It is found that the thicknesses of the nanocomposite films can be easily controlled in the range of 0.5-3 μm by dripping target amount of acetone dilu...

Wharton’s jelly mesenchymal stem cells (HWJMSCs) hold promise for myocardial regeneration, but optimal treatment regimen (preferably with a growth factor) is required to maximize functional benefits. The aim of this study was to explore the cardioprotective and angiogenesis effects of HWJMSCs combined with insulin-like growth factor-1 (IGF-1) in the treatment of acute myocardial infarction. Th...

A novel pH-responsive superabsorbent hydrogel based on gelatin was prepared through crosslinking copolymerization of poly (acrylic acid) and poly (itaconic acid). The copolymerization conditions including monomers, initiator, gelatin and crosslinker concentration, reaction temperature, and neutralization percent were systematically optimized to achieve a hydrogel with swelling capacity as high ...

Abstract In this paper, we introduce a nanocomposite as humidity-sensitive sound absorber. The nanocomposites were prepared using hydrogel polymer (HP) matrix and graphene oxide (GO) filler. Results show that the surface energy of is 58.4 mJ m −2 , GO sheets increase porosity from 2.6716 cm 2 g −1 (for HP) up to 3.246 . addition, diameter pores 8.5202 nm lower than HP (10.274 nm). To study effe...

Plasmonic heating finds multiple applications in cell manipulation and stimulation, where heat generated by metal nanoparticles can be used to modify adhesion, control membrane currents, suppress neuronal action potentials among others. Metal also easily integrated artificial extracellular matrices provide tunable, thermal cueing functionalities with nanometer spatial resolution. In this contri...
