Geostandards and Geoanalytical Research, Volume 49, Issue 2, Page 343-356, June 2025.Key Points An analytical strategy for determining boron isotope ratios in Ca‐amphiboles using LA‐MC‐ICP‐MS is presented. Accurate δ11B results can be achieved using the USGS BHVO‐2G glass as the calibrating reference material. Two proposed Ca‐amphibole RMs exhibit good homogeneity with δ11B intermediate measurement precision of 2.86‰ and 3.96‰ (2s ...

Sustainable Pathways for the Synthesis of Calcium Sulfate Hemihydrate
Angewandte Chemie International Edition, Volume 64, Issue 20, May 12, 2025.Calcium sulfate hemihydrate (bassanite) plays a key role in construction as a hydraulic binder. Due to its instability in water, industrial production primarily relies on thermal dehydration of gypsum. This review examines alternative, potentially more sustainable methods for the synthesis of bassanite, including gypsum conversion at lower temperatures

Advancements in Seawater Electrocatalysis for Renewable Energy Conversion and Resource Extraction
ChemElectroChem, Volume 12, Issue 9, May 5, 2025.This graphic highlights seawater electrocatalysis for sustainable energy and resource extraction, focusing on HER/OER mechanisms and material advances (non‐precious, precious, nonmetal, and bifunctional catalysts). It addresses electrocatalytic conversion of pollutants (hydrazine, urea, microplastics) and extraction of valuable ions (e. g., Li, U) from

Advanced Science, Volume 12, Issue 17, May 8, 2025.Strain localization along phase or grain boundaries leads to crack initiation typical of alloys. In multi‐principal element alloys, the enamel‐like microstructure is stabilized by phase boundaries. This facilitates trans‐phase migration of semi‐atomic surfaces and provides sufficient plastic space for dislocation‐mediated deformation.

Chemistry – A European Journal, Volume 31, Issue 25, May 5, 2025.Branched glycerol dialkyl glycerol tetraethers (brGDGT's) are membrane‐spanning lipids produced by Acidobacteria, and used extensively in geochemistry as proxies. The first total synthesis of brGDGT Ia has been achieved, elucidating the relative stereochemical configuration of the methyl branches in the chain as syn.

UniZyme: A Unified Protein Cleavage Site Predictor Enhanced with Enzyme Active-Site Knowledge [PDF]
arXivEnzyme-catalyzed protein cleavage is essential for many biological functions. Accurate prediction of cleavage sites can facilitate various applications such as drug development, enzyme design, and a deeper understanding of biological mechanisms. However, most existing models are restricted to an individual enzyme, which neglects shared knowledge of ...

Sedimentary ancient DNA from caves: Challenges and opportunities
Journal of Quaternary Science, Volume 40, Issue 4, Page 565-578, May 2025.Abstract Caves are unique depositional environments that hold great potential for long‐term preservation of DNA due to their typically cool and stable internal climates, buffered from external climate extremes. Bones from caves have long been recognised as an excellent source of ancient DNA, yet the potential for DNA preservation in cave sediments ...

Crystalline Water Structure in Room‐Temperature Clathrate State: Hydrogen‐Bonded Pentagonal Rings
Small Structures, Volume 6, Issue 5, May 2025.A room‐temperature crystalline water structure is derived by recording and analyzing electron diffraction patterns through transmission electron microscopy and by performing first‐principles calculations. The structure exists in mesoscopic clathrate hydrate structures, a novel clathrate state, which are prepared by sandwiching gas‐supersaturated water ...

Atomic structure and electronic properties of the cleavage InAs(110) surface [PDF]
arXiv, 2003 The electronic properties of the cleavage InAs(110) surface are studied using a semi-empirical tight-binding method which employs an extended atomic-like basis set. We calculate the surface electronic band structure which is studied as a function of the structural parameters of the surface.
