The Stability of Metallic MoS₂ Nanosheets and Their Property Change by Annealing (open access)

The Stability of Metallic MoS₂ Nanosheets and Their Property Change by Annealing

This article focuses on the effects of mild annealing on the structural and physical properties of the MoS₂ by heating the nanosheets in air and vacuum up to 350 °C. It was found that the annealing leads to an increase in resistivity for the nanosheets by 3 orders of magnitude, the appearance of two absorption bands in the visible range, and a hydrophilic to hydrophobic change in the surface wetting properties. Overall, this study provides another way to control the electrical, optical, and surface properties of MoS₂ nanosheets for fulfilling the needs of various applications.

Corrosion Behavior of Selectively Laser Melted CoCrFeMnNi High Entropy Alloy (open access)

Corrosion Behavior of Selectively Laser Melted CoCrFeMnNi High Entropy Alloy

The article focuses on a study that widens the toolbox to manufacture HEAs with exceptional corrosion resistance by additive manufacturing. CoCrFeMnNi high entropy alloys (HEAs) were additively manufactured (AM) by laser powder bed fusion and their corrosion resistance in 3.5 wt% NaCl solution was studied by potentiodynamic polarization and electrochemical impedance spectroscopy tests. A systematic study of AM CoCrFeMnNi HEAs’ porosity under a wide range of laser processing parameters was conducted and a processing map was constructed to identify the optimal laser processing window for CoCrFeMnNi HEAs.

Atomic layer deposition of h-BN(0001) multilayers on Ni(111) and chemical vapor deposition of graphene on h-BN(0001)/Ni(111) (open access)

Atomic layer deposition of h-BN(0001) multilayers on Ni(111) and chemical vapor deposition of graphene on h-BN(0001)/Ni(111)

Article studying atomic layer deposition. In situ direct, epitaxial growth of multilayers of hexagonal boron nitride (h-BN) and graphene without physical transfer is of significant interest for the scalable production of graphene/h-BN heterostructures for device applications. Deposition on magnetic substrates is of particular interest for spin tunneling applications. X-ray photoelectron spectroscopy and low energy electron diffraction demonstrate epitaxial atomic-layer deposition (ALD) of multilayer h-BN(0001) on Ni(111) and subsequent deposition of azimuthally-aligned multilayer graphene on h-BN(0001)/Ni(111) by chemical vapor deposition. Boron nitride ALD was accomplished with alternating cycles of BCl₃/NH₃ at a 600 K substrate temperature, and subsequent annealing in ultrahigh vacuum. Subsequent deposition of graphene was achieved by chemical vapor deposition using ethylene (CH₂CH₂) at 1000 K.

Article studying c/a ratio and transformation volume change of h.c.p. (hexagonal close packed) epsilon martensite phase in transformative high entropy alloys (HEAs) quantified as functions of alloy chemistry, friction stir processing and tensile deformation. The study reveals that while intrinsic c/a is dependent on alloying elements, c/a of epsilon in transformative HEAs changes with processing and deformation.

Parental stressor exposure simultaneously conveys both adaptive and maladaptive larval phenotypes through epigenetic inheritance in the zebrafish (Danio rerio) (open access)

Parental stressor exposure simultaneously conveys both adaptive and maladaptive larval phenotypes through epigenetic inheritance in the zebrafish (Danio rerio)

This article is a study using crude oil as an example of an environmental stressor in adult zebrafish. The offspring obtained were then assessed for transgenerational epigenetic transfer of oil-induced phenotypes. The authors conclude that epigenetic transgenerational inheritance can lead to an immediate and simultaneous inheritance of both beneficial and maladaptive traits in a large proportion of the F1 larvae. The adaptive responses may help fish populations survive when facing transient environmental stressors.
