Summary: This report investigates the reversible twinning in B19 ' martensite in a Nb-nanowire/NiTiFe-matrix alloy. The study achieves a twinning strain of up to 5.1% by pre-deforming the alloy. In situ synchrotron X-ray diffraction results reveal the generation of reversible twins, and the measured twinning strain clarifies the contribution of reversible twinning to twinning induced elasticity (TIE).

Summary: A critical assessment was conducted to determine the stacking fault energy (SFE) of the austenite phase in high manganese steels using X-ray diffraction (XRD), revealing a substantial variation in SFE with chosen elastic constants, leading to potential errors of up to 37%. The study aimed to establish a more direct and reliable methodology for calculating SFE by XRD, and found that uncertainty in elastic constants can significantly impact the estimated values.

Summary: In this study, a simple strategy was demonstrated for constructing low-tortuosity through-pores in both vertical and planar directions of electrodes by casting large particles into single-particle-layer electrodes. Through multi-scale characterizations and simulations, correlations between material/electrode structures, electrolyte permeability, polysulfide migration, and sulfur reactions were elucidated. The high-loading and dense sulfur cathode fabricated by this method delivers a high specific capacity at a very low electrolyte/sulfur ratio.

Summary: This study investigates the effects of high-pressure processing on food using orthorhombic L-glutathione as a crucial component in food proteins. Experimental results show that the sample undergoes two phase transitions in different pressure ranges and the strength of hydrogen bonding changes accordingly. In-situ methods such as high-pressure Raman, infrared, and X-ray diffraction were utilized to analyze structural changes.

Summary: Lab-scale X-ray diffraction and in situ heating neutron diffraction were conducted to evaluate structural changes in an additive-manufactured (AM) 316L stainless steel. The study found sequential structural relaxation and linear thermal lattice expansion in the nanostructured AM steel during heating, and observed different relaxation behaviors based on changes in crystallite sizes and dislocation densities. Furthermore, the manuscript connects critical subjects in materials science of advanced manufacturing, metal processing, and properties with novel time-resolved characterization techniques.

Summary: Layered nickel-rich materials have been considered promising cathode candidates for solid-state batteries, but they suffer from low Coulombic efficiency and poor cycle stability at high cutoff potentials. This study investigates the bulk structure evolution of LiNi0.8Co0.1Mn0.1O2 cathode material in solid-state batteries and reveals the crucial role of surface chemistry in the degradation mechanism and performance enhancement. The results demonstrate that surface coating not only suppresses interfacial side reactions but also eliminates sluggish phase, leading to improved performance.

Summary: Recent theoretical predictions have suggested that two-dimensional van der Waals materials may exhibit ferroelectric properties, opening up exciting possibilities for scalable low-power electronic devices. Experimental evidence of polarization response has been observed in narrow-band semiconductors and semimetals known as transition metal chalcogenides (TMCs), with molybdenum disulfide (MoS2) being one of the most promising 2D electronic materials. However, despite theoretical predictions, no ferroelectricity has been experimentally detected in MoS2, although its emergence could enhance its potential for electronics applications.

Summary: The presence of in-plane chiral effects and spin-orbit coupling in a TiS3(001) field-effect phototransistor is confirmed through changes in the photocurrent caused by left versus right circularly polarized light. NanoARPES measurements indicate that the direction of the photocurrent is protected by strong spin-orbit coupling and the anisotropy of the band structure. Dark electronic transport measurements show that TiS3 is n-type with an electron mobility ranging from 1-6 cm(2)V(-1)s(-1). I-V measurements under laser illumination demonstrate that the photocurrent exhibits bias directionality dependence similar to bipolar spin diode behavior. The presence of spin-orbit coupling in TiS3, a material without heavy elements, is attributed to the loss of inversion symmetry at the TiS3(001) surface.

Summary: The synthesis of beta-NaYF4 nanocrystals from alpha-NaYF4 precursor particles was investigated using in situ small-angle and wide-angle X-ray scattering and ex situ electron microscopy. It was observed that the particle size distribution evolved from unimodal to bimodal, and eventually back to unimodal, with the final distribution being narrower than the initial distribution. The splitting of the size distribution was attributed to variations in the reactivity of the precursor particles.

Summary: We modified a gas phase ultrafast electron diffraction (UED) instrument to conduct experiments on both gas and condensed matter targets. The modified instrument demonstrated sub-picosecond time-resolved experiments with solid state samples. By using a hybrid DC-RF acceleration structure, femtosecond electron pulses are delivered to the target synchronized with femtosecond laser pulses. The new system allows for transmission UED on thin solid samples, as well as cooling samples to cryogenic temperatures and carrying out time-resolved measurements. The cooling capability was tested on 1T-TaS2 for diffraction patterns of temperature dependent charge density waves, and the time-resolved capability was verified by capturing dynamics in photoexcited single-crystal gold.

Summary: This study proposes a highly tunable gas sensor strategy by combining MXene with a sacrificial material that can be controlled oxidized to form oxide nanoparticles, altering sensing response. The controlled annealing process retains the integrity of MXene sheets while converting the sacrificial material to a metal oxide, fine-tuning the sensor properties. The approach is demonstrated using Ti3C2Tx MXene mixed with TiS3, showing improved sensor response to ethanol. The addition of TiS3 allows for the preservation of MXene as the sensor material and the tuning of sensor properties through annealing for specific analytes or applications.

Summary: MXenes are a diverse family of two-dimensional materials that can be synthesized by selectively etching A-elements from layered MAX phases. This study presents a strategy for A-modified MXenes, where the higher reactivity of the A'-element enables its selective etching and results in A''-modified MXenes. The incorporation of Sn in Ti3AlC2 MAX phase and subsequent etching produces Sn-modified Ti3C2Tz MXene with improved environmental stability and interesting electrostatic expansion properties.

Summary: This paper demonstrates the fabrication of nanometer-scale metal contacts on individual graphene nanoribbons (GNRs) and the use of these contacts to control the electronic character of the GNRs. Using a low-voltage direct-write STM-based process, sub-5 nm metallic hafnium diboride (HfB2) contacts are patterned directly on top of single GNRs in an ultrahigh-vacuum scanning tunneling microscope (UHV-STM), with all the fabrication performed on a technologically relevant semiconductor silicon substrate. Scanning tunneling spectroscopy (STS) data verify the expected metallic and semiconducting character of the contacts and GNR, and also show induced band bending and p-n junction formation in the GNR due to the metal-GNR work function difference. Contact engineering with different work function metals eliminates the need for complex chemical doping to create GNRs with different characteristics. This paper demonstrates the successful fabrication of precise metal contacts and local p-n junction formation on single GNRs.

Summary: This paper discusses Leonardo da Vinci's area-preserving rule for botanical trees, focusing on its connection to a specific fractal structure called a logarithmic fractal. Using numerical Fourier analysis, the researchers analyze the logarithmic fractal properties of the branching system of real trees in two-dimensional space, based on photographs. They find that different species of trees exhibit a Q(-2) decay in the spectral intensity, indicating a logarithmic fractal structure in the two-dimensional space. Additionally, the experiments involving the side view of the trees suggest that a rule involving the product of branch diameter and length complements Leonardo's area-preserving rule. The findings suggest that while a tree as a three-dimensional object is not a logarithmic fractal, its projection onto a two-dimensional plane is.
