On the evolving nature of c/a ratio in a hexagonal close-packed epsilon martensite phase in transformative high entropy alloys (open access)

On the evolving nature of c/a ratio in a hexagonal close-packed epsilon martensite phase in transformative high entropy alloys

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.

Revisiting surface core-level shifts for ionic compounds (open access)

Revisiting surface core-level shifts for ionic compounds

Article establishing a theoretical method which is able to relate the binding energy shifts to the electronic structure of a material. In order to establish such a methodology, the CaO(100) surface to bulk core-level binding energy shifts are studied with Hartree-Fock and density-functional theory methods using both cluster and periodic slab models.

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.

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.

Artificially structured boundary plasma trap

This article presents a computer simulation of single-species non-neutral plasma confinement using an artificially structured boundary. The results support the prospect of developing plasma space-charge based confinement, with an unmagnetized plasma of one species of charged particles confined by an electric field produced by an edge-confined plasma of a second species of charged particles.

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.

Preparation and Characterization of 3D Printed PLA-Based Conductive Composites Using Carbonaceous Fillers by Masterbatch Melting Method (open access)

Preparation and Characterization of 3D Printed PLA-Based Conductive Composites Using Carbonaceous Fillers by Masterbatch Melting Method

This article highlights a study aimed at improving the conductivity of polylactic acid (PLA)-based composites by incorporating carbonaceous fillers. The composites with the addition of graphene nanoplatelets (rGO) or multi-walled carbon nanotubes (MWCNTs) were fabricated by the masterbatch melting method in order to improve the dispersion of the two kinds of nano-fillers. The results showed that, with the addition of 9 wt % rGO, the volume electrical resistivity of the composite reached the minimum electrical resistance of 10³ Ω·m, at which point the conductive network in the composites was completely formed.
