The morphological, structural, and electrical properties of as-grown and annealed GeSbTe (GST) layers, deposited by RF-sputtering on flexible polyimide, were studied by means of optical microscopy, atomic force microscopy, X-ray diffraction, Raman spectroscopy, and electrical characterization. The X-ray diffraction annealing experiments showed the structural transformation of GST layers from the as-grown amorphous state into their crystalline cubic and trigonal phases. The onset of crystallization of the GST films was inferred at about 140 °C. The vibrational properties of the crystalline GST layers were investigated via Raman spectroscopy with mode assignment in agreement with previous works on GST films grown on rigid substrates. The electrical characterization revealed a good homogeneity of the amorphous and crystalline trigonal GST with an electrical resistance contrast of 8 × 10.

Introduction: Glutathione S-transferase (GST) has the ability to detoxify the cellular environment of xenobiotic compounds and by-products of oxidative stress. The expression levels of GST genes and their polymorphisms are associated with various human diseases. Methamphetamine and opiate addiction also account for a significant proportion of SUDs in Iran.

Surface induced crystallization/amorphization of a Germanium-antimony-tellurium (GST) nanolayer is investigated using the phase field model. A Ginzburg-Landau (GL) equation introduces an external surface layer (ESL) within which the surface energy and elastic properties are properly distributed. Next, the coupled GL and elasticity equations for the crystallization/amorphization are solved.

This study explored the effects of melatonin on cardiac and vascular function, and redox homeostasis in model PAH. Male Wistar rats were divided into: control (CTR), monocrotaline [MCT (60 mg/kg, single dose i.p)], monocrotaline + sildenafil [MCT + SIL (50 mg/kg/day)], and monocrotaline + melatonin [MCT + MEL (10 mg/kg/day)].

Psoriasis is a long-term inflammatory skin condition marked by an overabundance of keratinocytes and the release of pro-inflammatory cytokines in the outer layer of skin. For the comprehensive management of intermediate to advanced psoriasis, innovative biological treatments have been developed. Products for the superficial therapy of mild to moderate psoriasis are still necessary, though.

Materials with anisotropic emission characteristics have attracted considerable attention for thermal management. Although many dual-mode emitters have been developed for this purpose in the form of textiles, multilayer films, and photonic structures, multiple functionalities are essential for their versatile applications. Herein, a highly stretchable dual-mode emitter with programmable emissivity and air permeability is presented.
