Direct chemical vapor deposition (CVD) of graphene on any desired substrate is always required to manufacture high-quality heterojunctions with excellent interfacial properties. Herein, the growth cubic-silicon carbide (3C-SiC) surfaces using conventional high-temperature direct thermal CVD and plasma-enhanced (PECVD) explored, which hardly reported date. Since 3C-SiC substrates are not available, controlled self-limited layers Si(100) were grown at different temperatures (900–1200 °C) via...

Abstract Biosensors are analytical tools that integrate a biological element with physicochemical detector in order to quantify the existence or concentration of chemicals, biomolecules, other elements for human health monitoring purposes. Electrochemical techniques analyte detection include use electrochemical sensors identify and molecules. These often used because their high sensitivity, specificity, quick reaction time, possibility being made smaller size, but still, research problem...

Summary. The clinical phenotype of patients with haemophilia A (HA) often differs between individuals the same factor VIII (FVIII) gene defect (e.g. within family) or coagulant activity FVIII (FVIII:C). We proposed that because thrombin generation assay in platelet‐poor plasma HA provides more information [peak concentration, endogenous potential (ETP), rate and lag‐time] than a clot‐based it might provide insight into these differences. therefore investigated relation results severity nine...

Abstract In this work, porous silicon (P-Si) structures were fabricated by anodizing n-type monocrystalline Si into an ethanoic-HF solution. Anisotropic electrochemical etching with constant time and current density was carried out to fabricate pores their average diameter found be <?CDATA ${\sim}700\ \text{nm}$ ?> . Raman spectra exhibited widened peaks for red, blue, green wavelengths. The photoluminescence (PL) spectrum blue-shifted owing the quantum confinement effect. P-Si energy gap of...

Hydrogenated graphene is easy to prepare and chemically stable. Besides, hydrogenation of can open the band gap, which vital for electronic optoelectronic applications. Graphene/Si photodetector (PD) has been widely studied in imaging, telecommunications, other fields. The direct contact between Si form a Schottky junction. However, it suffers from poor interface state, where carrier recombination at causes serious leakage current, turn leads decrease detectivity. Hence, this study,...

Photodetectors (PDs) are widely used in various fields of military and daily life especially for imaging, telecommunications, sensing, so on. Therefore, high performance low power consumption crucial importance PDs with detectivity fast response speed. Self-powered have the advantage cost, which can be fabricated by direct contact graphene silicon (Si). However, graphene/Si Schottky structure suffers from interface trap states junction barrier. Such drawbacks reduce speed increase noise...

Abstract Second-generation tyrosine kinase inhibitors (2GTKI) are more effective in inducing rapid molecular responses than imatinib when used first-line patients with chronic myeloid leukemia phase (CML-CP). However, failure of first line-2GTKI (1L-2GTKI) still occurs and there is no consensus regarding subsequent management. We retrospectively analyzed the outcome 106 CML-CP treated 1L-2GTKI a median follow-up 91 months. 45 (42.4%) switched to an alternative TKI, 28 for intolerance (26.4%)...

Abstract 2D material‐based electronic devices like graphene–silicon photodetectors (Gr–Si PDs) have attracted much attention of researchers in the past few years. Due to nature Schottky junction, Gr–Si PDs ultrafast response. However, responsivity is very low, which hinders their practical application. Low work function Gr and poor absorbance Si are mainly responsible for this problem. Here, a novel approach coupling with fractal platinum nanoparticles (Pt NPs) demonstrated enhance speed up...

Abstract This first principles study explores the structural, electronic, optical, and thermoelectric properties of CsTmCl 3 halide perovskite using density functional theory.
