Inkjet-printed graphene’s electrical response to external gas flow for sensing applications (open access)

Inkjet-printed graphene’s electrical response to external gas flow for sensing applications

Article discusses how understanding gas flow behavior is crucial in the ability of materials to sense toxic gasses for environmental, industrial, safety, agriculture, and related applications. In their study, the authors measure the electrical transport characteristics of ink jet printed graphene to incoming gas flow, specifically to N2 and CO2. This work serves as a prototypical platform to study the device characteristics of solution processed graphene and other 2D materials for more exotic gases in the future for gas sensing applications.

Light-matter Interactions in Transition Metal Dichalcogenides and Organohalide Perovskites for Photoabsorbers and Solar Cells (open access)

Light-matter Interactions in Transition Metal Dichalcogenides and Organohalide Perovskites for Photoabsorbers and Solar Cells

Article discusses findings on two distinct classes of van der Waals solids, that based on in-organic transition metal dichalcogenides and the other based on a hybrid mixed organic-inorganic composition of 2D perovskites, specifically organo-halides (CH3(CH2)3NH3)2(CH3NH3)n-1PbnI3n+1.

Photoexcitation of C₆₀-WSe₂ hybrids for optical sensing (open access)

Photoexcitation of C₆₀-WSe₂ hybrids for optical sensing

Article discusses a study on synthesizing 0D-2D vdW heterostructure by spin coating C60 molecules on halide-assisted-low-pressure chemical-vapor-deposition (HA-LPCVD) produced monolayer WSe2 flakes. The study reveals that WSe2-C60 hybrid system is an appealing choice for next generation optical sensing devices.

Solution-processed dielectric films and Au RF antenna for temperature sensing (open access)

Solution-processed dielectric films and Au RF antenna for temperature sensing

Article discusses how sensing temperature is important for a wide variety of applications such as control systems and instrumentation which are integral to various industrial sectors and in research settings. The authors emphasize the importance of high sensitivity and reliable methods using a frequency-based approach for detecting temperature changes. In their study, Au rectangular single-arm spiral antennas with varying sizes were fabricated and RF S-parameter measurements were conducted over the frequency range of 300 kHz to 20 GHz. Alongside the experimental measurements, they also present results from their simulation analysis conducted using High Frequency Structure Simulator (HFSS) from ANSYS.

Effect of composition and thermal history on deformation behavior and cluster connections in model bulk metallic glasses (open access)

Effect of composition and thermal history on deformation behavior and cluster connections in model bulk metallic glasses

Article describes the compositional dependence and influence of relaxation state on the deformation behavior of a Pt–Pd-based bulk metallic glasses model system was investigated, where platinum is systematically replaced by topologically equivalent palladium atoms. Based on total scattering experiments with synchrotron X-ray radiation, a correlation between the increase in stiffer 3-atom cluster connections and reduction in strain-rate sensitivity, as a measure of ductility, with Pd content and thermal history is suggested.

Predicting initial dissolution rates using structural featuresfrom molecular dynamics simulations (open access)

Predicting initial dissolution rates using structural featuresfrom molecular dynamics simulations

Article states that predicting the chemical durability of glass materials is important for various applications from daily life such as cell phone screens and kitchenware to advanced technologies such as nuclear waste disposal and biomedicine. In this work, we explored the prediction of the initial glass dissolution rates using structural features from molecular dynamics (MD) simulations for a series of glass compositions (total 28), including ZrO2- and V2O5-containing boroaluminosilicate, borosilicate, and aluminosilicate glasses.

Editorial: Superlubricity across the scales (open access)

Editorial: Superlubricity across the scales

Article talks about how while the idea of frictionless surfaces and the associated implications of vanishing energy losses during mechanical motion have been part of science fiction culture, scientists in the real world work toward realizing this ambitious goal that was once thought to be unattainable. The overarching goal of the research topic titled “Superlubricity Across the Scales” is to provide a snapshot of the latest developments in this rapidly accelerating field of research.
