It has recently been suggested that the driven lattice gas should be described by an alternate field theory in the limit of infinite drive. We review the original and the alternate field theory, invoking several well-documented key features of the microscopics. Since the alternate field theory fails to reproduce these characteristics, we argue that it cannot serve as a viable description of the driven lattice gas. Recent results, for the critical exponents associated with this theory, are reanalyzed and shown to be incorrect.

Solar-driven CO reduction to value-added C chemicals is thermodynamically challenging due to multiple complicated steps. The design of active sites and structures for photocatalysts is necessary to improve solar energy efficiency. In this work, atomically dispersed Ru-O sites in RuInO are constructed by interior lattice anchoring of Ru.

This study investigates the influence of prolonged electrolysis on the electrochemical performance and surface characteristics of NiFe-modified compressed graphite electrodes used in alkaline water electrolysis. The electrochemical experiment was conducted over a two-week period at a constant temperature of 60 °C. The electrodes were evaluated for changes in surface morphology and composition using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and X-ray diffraction (XRD).

Ever-increasing demand for efficient optoelectronic devices with a small-footprinted on-chip light emitting diode has driven their expansion in self-emissive displays, from micro-electronic displays to large video walls. InGaN nanowires, with features like high electron mobility, tunable emission wavelengths, durability under high current densities, compact size, self-emission, long lifespan, low-power consumption, fast response, and impressive brightness, are emerging as the choice of micro-light emitting diodes (µLEDs). However, challenges persist in achieving high crystal quality and lattice-matching heterostructures due to composition tuning and bandgap issues on substrates with differing crystal structures and high lattice mismatches.

The reduced dimensionality of thin transition metal dihalide films on single-crystal surfaces unlocks a diverse range of magnetic and electronic properties. However, achieving stoichiometric monolayer islands requires precise control over the growth conditions. In this study, we employ scanning probe microscopy to investigate the growth of MnI on Ag(111) via single-crucible evaporation.

Article Synopsis
- All-solid-state lithium metal batteries are promising for high energy density and safety, but issues like voids at the anode/electrolyte interface during lithium stripping can hurt stability.
- Stack pressure and operating temperature can induce creep deformation in lithium metal, potentially improving interfacial issues caused by these voids, although understanding of these effects is still lacking.
- A new coupled model (EDMP-VE) has been developed to study the influence of pressure and temperature on void evolution, showing that higher conditions can enhance void healing and stabilize interfaces by reducing void expansion and promoting filling.
