In the management of burn wounds, antimicrobial and wound healing properties are crucial. In this study, we prepared a three-layer electrospun poly(ε-caprolactone) (PCL) membrane for burn wound dressing. The hydrophobic electrospun PCL layer, embedded with silver nanoparticles (SNPs) (PCL-Ag), was coated with another layer of electrospun plasma-treated PCLAg to enhance the wettability of the membrane.

The solution plasma process (SPP) is a revolutionary approach for production of nanomaterials employing plasma discharge in liquid. The SPP can quickly deionize metal into the neutral state in the absence of a reducing agent. Selenium nanoparticles are created in solution plasma in this investigation.

Heterogeneous Fenton-like removal of Acid Red 17 (AR17) from aqueous solution was investigated. Feimpregnated nanoporous clinoptilolite (Fe-NP-Clin) was prepared by an impregnation method and used as a catalyst. A complete characterization including X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), inductively coupled plasma (ICP), and Brunauer–Emmett–Teller (BET) analyses was done to describe the physical and chemical properties of NP-Clin and Fe-NP-Clin samples.

This work reports the synthesis and properties of a new membrane based on polyvinyl chloride (PVC) grafting with polyacrylic acid (PAA) using argon (Ar) plasma. The membranes of PVC were synthesized by solutioncasting method, where PAA was deposited as an ultrathin film onto PVC using dielectric barrier discharge at atmospheric pressure with Ar gas. The surface characteristics and chemical composition of the modified membranes were analyzed by water contact angle, scanning electron microscopy, and Fourier transform infrared spectroscopy.

In this study, microwave-assisted ammonia decomposition reaction was investigated over molybdenum incorporated catalysts. Due to the selective, volumetric, and noncontact heating properties of the microwave system, higher conversion values could be achieved at relatively lower reaction temperatures, which is important for on-site COx-free hydrogen production. Multiwall carbon nanotube-supported molybdenum catalysts were prepared following the impregnation procedure with different metal loading (3.5%–12.

Statins are widely prescribed to lower plasma low-density lipoprotein cholesterol levels. Though statins reduce cardiovascular disease risk overall, statin efficacy varies, and some people experience adverse side effects while on statin treatment. Statins also have pleiotropic effects not directly related to their cholesterollowering properties, but the mechanisms are not well understood.

Ultrathin silicon nitride SiNx membrane suspended on a silicon wafer is a popular twodimensional platform in MEMS applications. The unsupported membrane has a low thermal conductivity, is electrically insulated, and very robust against mechanical impact. Remarkably thin, it is difficult to fabricate and manipulate. Recently equipped with a dual chamber system for plasma enhanced chemical vapor deposition (PECVD) and reactive ion etching, we calibrate it to deposit silicon nitride Si3N4, silicon dioxide SiO2, and to dry etch these materials.

This paper assessed impact of dilution on the microstructure and properties of the Ni alloy In 625 deposited by Plasma Transferred Arc (PTA) on two substrates: carbon steel API 5LX70 (API 5L) and stainless steel AISI 316L. Differences due to the interaction with the substrate were maximized analyzing single layer coatings, processed with three deposition current: 120 A, 150 A and 180 A. Dilution was determined by the area ratio and Vickers hardness measured on the transverse section of coatings.

This paper assessed influence of dilution on the microstructure, mechanical properties and microhardness of a cobalt-based alloy deposited by plasma transferred arc (PTA) on three steel substrates. Dilution was analyzed by energy dispersive spectroscopy (EDS). Microstructure was analyzed by the optical microscopy (OM) and scanning electron microscopy (SEM). Microhardness measured on the scross section of coatings. Analysis results show that, the dilution ratio, microstructure and microhardness of the coating influenced by the welding parameters and substrates.

A new host phosphors of LaSr2AlO5 doped with Ce and Eu was synthesized using a solid-state reaction method and the synthesis conditions were investigated. The samples were characterized by X-ray diffraction, scanning electron microscopy, photoluminescent (PL) and photoluminescent excitation (PLE) spectra. LaSr2AlO5:Ce shows a yellow emission at about 570 nm after an excitation at about 450 nm while LaSr2AlO5:Eu presents a red emission.
