Critical Review of Brazil Disk Techniques for Tensile Strength Characterization With an Emphasis on High Explosive Materials

Propellants, Explosives, Pyrotechnics, EarlyView.
ABSTRACT Mechanical properties are a critical performance metric for many high explosive (HE) materials and tensile strength properties are particularly important. Direct tensile measurements using dogbone shaped samples are the gold standard but they have the disadvantage that they are fairly large and require samples machined from billets.

Evaluation of Potential Hormonal Activities of Ashwagandha (Withania somnifera)

Phytotherapy Research, EarlyView.
ABSTRACT Ashwagandha is a widely used herb in traditional medicine systems, particularly Ayurveda. Despite its extensive tradition, growing concerns regarding its potential endocrinological effects have prompted scientific scrutiny. This review systematically evaluates the current preclinical, clinical, and case study evidence concerning AS's effects ...

A flexible arched artificial photoreceptor constructed by photodeformable liquid crystal polymers and its application in vision restoration

Smart Molecules, EarlyView.
A flexible arched artificial photoreceptor with high stability and biocompatibility was fabricated by integrating liquid crystal polymers with polyvinylidene fluoride‐trifluoroethylene. This device exhibits robust photoelectric responses under low‐intensity illumination and demonstrates efficacy in restoring visual responses in blind rats following ...

HRTEM Imaging and Mechanistic Insights Into Carbon Nanotube Nucleation and Growth on Fe Nanocatalysts in a Thermal Plasma

Small Methods, EarlyView.
Carbon nanotubes (CNTs) were successfully debundled from Tuball soots produced using iron nanocatalysts in arc discharge thermal plasma and distributed on monolayer graphene for HRTEM imaging for mechanistic insights into CNT synthesis. Zigzag single‐wall or double‐wall CNTs were identified.

Analyses of the Deformability and Chemistry of Non‐Metallic Inclusions in QT Steels With Increased Recycling‐Induced Tramp Element Content

steel research international, EarlyView.
This work uses high‐temperature dilatometry to examine how the tramp elements Cu, Ni, and Sn affect the deformability of non‐metallic inclusions and matrix in quench‐and‐temper steel. Mg‐bearing inclusions deform less than Mg‐free ones. Copper lowers formability. Nickel increases deformability.

Influence of Tramp Elements on Phase Transformations, Structure, and Properties of Scrap‐Based Steels: A Focused Review of Recent Developments

steel research international, EarlyView.
This review explains how impurities from recycled scrap affect steel production and performance. Even small amounts (far below 1%) of these impurities can change how steel behaves during fabrication but also affect the properties of the end product. With better understanding and targeted countermeasures, these challenges can be managed, enabling wider ...

Tailoring Microstructure and Hardness in Maraging 300 Steel via 2.4 wt.% Niobium Addition and Controlled Aging Treatments

steel research international, EarlyView.
High Nb (2.4 wt.%) addition to Maraging 300 steel drives lattice distortion and nanoscale Nb–Mo‐rich precipitation, confirmed by energy‐dispersive X‐ray spectroscopy mapping (Mo ~5.4 wt.%, Nb ~2.5 wt.%). Nanoindentation reveals strong matrix hardening (H >4.8 GPa) at 480°C aging, while 560°C induces ~1.92 vol.% reverted austenite, enabling tunable ...

Mobile electromagnetic levitator for time‐resolved in situ X‐ray diffraction studies of high‐temperature phase transformations

Journal of Synchrotron Radiation, EarlyView.
A mobile electromagnetic levitator combined with time‐resolved synchrotron X‐ray diffraction enables in situ studies of high‐temperature phase transformations without container‐induced contamination and reveals the first direct observation of metastable phase formation in undercooled Fe–Co alloys.In situ observations of high‐temperature transformations,

‘From the Fields Into the Bars’: The Story of Israel's First Transgender Novel, The Cut (1977)

Gender &History, EarlyView.
ABSTRACT In 1977, an Israeli transgender woman, Judy Spotheim, published an autobiographical novel entitled The Cut. It describes the emergence of a trans community in the commercial‐sex areas of Tel Aviv‐Jaffa, hoping to humanise trans women (coccinelles). This article is the first to study the novel and present a biography of Spotheim.
