Abstract Over the past decade, cold atmospheric plasmas have shown promising application in cancer therapy. The therapeutic use of plasma-activated media is a topic addressed an emerging field known as plasma pharmacy. In oncology, are used to harness effects oxidant species when they come contact with cells. Among several factors that contribute anticancer effect liquid (PALM), H 2 O and NO derivatives likely play key role apoptotic pathway. Despite significant amount literature produced...
Abstract Water‐stable metal halide perovskites could foster tremendous progresses in several research fields where their superior optical properties can make differences. In this work we report clear evidence of water stability a lead‐free perovskite, namely DMASnBr 3 , obtained by means diffraction, and X‐ray photoelectron spectroscopy. Such unprecedented water‐stability has been applied to promote photocatalysis aqueous medium, particular devising novel composite material coupling g‐C N 4...
A facile atmospheric pressure cold plasma process is presented to deposit a novel organic-inorganic hydrocarbon polymer/ZnO nanoparticles nanocomposite coating. Specifically, this method involves the utilization of an dielectric barrier discharge (DBD) fed with helium and aerosol dispersion oleate-capped ZnO (NPs) in n-octane. As assessed by X-ray photoelectron spectroscopy (XPS) attenuated total reflectance-Fourier transform infrared (ATR-FTIR) spectroscopy, deposited coating combines...
A novel 2D lead-free perovskite showing stability in water and providing efficient hydrogen photogeneration.
Over the past 10 years, organometal halide perovskites have revolutionized field of optoelectronics, particularly emerging photovoltaic technologies. Today's best perovskite solar cells use triple-cation compositions containing a mixture formamidinium, methylammonium, and cesium to enable more reproducible stable device performance. The common procedure uses as-prepared precursor ink avoid an undesirable decrease in performance, attributed recently chemical reaction between methylammonium...

The composition of films deposited in RF glow discharges fed with tetraethoxysilane and oxygen mixtures has been investigated by means situ x‐ray photoelectron spectroscopy infrared spectroscopy. These results, combined mass spectrometric investigations the gas phase, indicate that overall deposition consists several concurrent heterogeneous homogeneous reactions.
Abstract In this paper, we review different plasma processes developed in our laboratory to obtain nanostructured superhydrophobic polymer surfaces. All methods consist of a single step and lead functional materials which combine fluorinated chemistry with unique surface morphologies. The transition from sticky slippery superhydrophobicity, crucial for several applications ranging microfluidics outdoor self‐cleaning surfaces, is found by properly tuning process parameters. Methods are...

A new protocol for biodiesel production is proposed, based on a binary ZnO/TBAI (TBAI = tetrabutylammonium iodide) catalytic system. Zinc oxide acts as heterogeneous, bifunctional Lewis acid/base catalyst, while TBAI plays the role of phase transfer agent. Being composed by bulk form powders, whole catalyst system proved to be easy use, without requiring nano-structuration or tedious and costly preparation pre-activation procedures. In addition, due amphoteric properties ZnO, can...
