Multiscale hierarchical and heterogeneous mechanical response of additively manufactured novel Al alloy investigated by high-resolution nanoindentation mapping
Article contains a study that combined multiscale nanomechanical and microstructural mapping to illustrate mechanical signatures associated with hierarchical heat distribution and rapid solidification of laser-powder bed fusion additive manufacturing (L-PBFAM). The presented approach serves as a high throughput methodology to establish the chemistry-processing-microstructure-properties correlation of newly designed alloys for L-PBFAM.

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.

Using representational and abstract imagery to createregulatory fit effects
Article asserts that visual imagery is one of the most important methods of communicating with consumers, but scholars have generally neglected the role of different forms of visual imagery (representational and abstract). The authors demonstrate that prevention-focused versus promotion-focused mindsets guide the interpretation of meanings conveyed by representational versus abstract visual imagery as a nonverbal means to achieve regulatory fit.

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.

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.

Scalable, top-down optical lithography for electrically contacting monolayer crystallites of vapor grown WSe2 for gas sensing applications
Article discusses how semiconducting two-dimensional transition-metal dichalcogenides (TMDs) have garnered a great deal of interest owing to their large surface-to-volume ratios compared to traditional three-dimensional (3D) semiconductors, and focuses on a specific TMD; tungsten diselenide (WSe₂). In their study, the authors demonstrate the halide-assisted low-pressure chemical vapor deposition (HA-LPCVD) of high crystalline-quality, monolayer WSe₂.

A consensus statement on detection of hippocampal sharp wave ripples and differentiation from other fast oscillations
Article suggests that common standards for recording, detection, and reporting for intracranial recordings in humans that suggest their role in episodic and semantic memory does not exist. Authors of the article outline the methodological challenges involved in detecting ripple events and offer practical recommendations to improve separation from other high-frequency oscillations, and argue that shared experimental, detection, and reporting standards will provide a solid foundation for future translational discovery.

Urban and air pollution: a multi-city study of long-term effects of urban landscape patterns on air quality trends
This article identifies the key urban form determinants of decadal-long fine particulate matter (PM2.5) trends in all 626 Chinese cities at the county level and above. As the first study of its kind, this study comprehensively examines the urban form effects on air quality in cities of different population sizes, at different development levels, and in different spatial-autocorrelation positions.

Autoencoder Composite Scoring to Evaluate Prosthetic Performance in Individuals with Lower Limb Amputation
Authors of the article created an overall assessment metric using a deep learning autoencoder to directly compare clinical outcomes in a comparison of lower limb amputees using two different prosthetic devices—a mechanical knee and a microprocessor-controlled knee. The proposed methods were used on data collected from ten participants with a dysvascular transfemoral amputation recruited for a prosthetics research study.

Corrosion Inhibition Effect of Pyridine-2-Thiol for Brass in An Acidic Environment
Article states that the inhibitive performance of pyridine-2-thiol added to a corrosive solution was investigated for brass using potentiodynamic polarization, electrochemical impedance spectroscopy, and X-ray photoelectron spectroscopy. Scanning electron microscopy showed defect free and less scale formation for the inhibited surface but the bare brass surface had larger amounts of scale formation. X-ray photoelectron spectroscopy and UV-vis spectroscopy was used to investigate surface chemical composition and inhibitor structural changes over time.
