Alloying indium into the topological insulator ${\mathrm{SnBi}}_{2}{\mathrm{Te}}_{4}$ induces bulk superconductivity with critical temperatures ${T}_{c}$ up to 1.85 K and upper fields about 14 kOe. This is confirmed by electrical resistivity, heat capacity, magnetic susceptibility measurements. The capacity shows a discontinuity at temperature dependence below consistent weak coupling BCS theor...

A thermal atomic layer deposition (ALD) process to fabricate MoS2 thin films is successfully demonstrated by using cycloheptatriene molybdenum tricarbonyl (C7H8Mo(CO)3) and H2S as precursors at an ALD temperature below 300 °C. The systematically investigated, showing a typical self-limiting characteristic within window of 225–285 °C high growth-per-cycle 0.11 nm. as-deposited are amorphous whil...

Background: Trichophyton rubrum (T. rubrum) is the most common cause of dermatophytosis of skin and nail tissue. Strain identification in Trichophyton rubrum is important for identification of strain-related differences in infectivity potential or transmissibility and epidemiological studies. PCR typing could determine whether the original isolate is responsible for re-infection or a new strain...

Diamond has compelling advantages in power devices as an ultrawide-bandgap semiconductor. Using first-principles calculations, we systematically investigate the structural and electronic properties of hydrogen-terminated diamond (H-diamond) (111) van der Waals (vdW) heterostructures with graphite hexagonal boron nitride (h-BN) layers. The graphite/H-diamond heterostructure forms a p-type ohmic ...

Two-dimensional (2D) van der Waals (vdW) heterostructures currently have attracted much attention in widespread research fields where semiconductor materials are key. With the aim of gaining insights into photocatalytic materials, we use density functional theory (DFT) calculations within HSE06 to analyze evolution optoelectronic properties and high-frequency dielectric constant profiles variou...

mobile carrier properties of two schiff base ligands, named bis(2-hydroxypropiophenone)-1,2-propanediimine (n2o2) and bis(1'-hydroxy-2'-acetonaphthone)-2,2'-diiminodiethylamine (n3o2), dissolved in dichloromethane for the extraction of copper(ii) ions from an ammonium buffer feed phase into a nitric acid solution (receiving phase) were investigated and compared. the parameters influencing the t...

We designed and successfully fabricated a ZnS/CdS 3D mesoporous heterostructure with a mediating Zn1-x Cd x S interface that serves as a charge carrier transport channel for the first time. The H2-production rate and the stability of the heterostructure involving two sulfides were dramatically and simultaneously improved by the careful modification of the interface state via a simple post-annea...
