Dental Microwear Texture Analysis on Radular Teeth
Advanced Materials Interfaces, EarlyView.3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.

[O─I─O]+ Halogen‐Bonded Complexes of Pyridine N‐Oxides
Angewandte Chemie, EarlyView.The missing puzzle of 3‐center‐4‐electron halogen‐bonded complexes viz. [O─I─O]+ of pyridine N‐oxides are structurally characterized by x‐ray diffraction. Monodentate N‐oxide O‐atom acts as the halogen bond acceptor. Their solution complexations are characterized by 15N NMR spectroscopy.

The use of diatom records to establish reference conditions for UK lakes subject to eutrophication [PDF]
, 2011 A knowledge of pre-disturbance conditions is important for setting realistic restoration targets for lakes. For European waters this is now a requirement of the European Council Water Framework Directive where ecological status must be assessed based on ...

Advanced Optical Materials, EarlyView.A new luminescence mechanism in Cs2NaInCl₆ is revealed through spontaneously formed In3+→In+ centers and Er3+/Yb3+/Sb3+ doping. Tunable visible, near‐infrared, downconversion, and upconversion emissions are demonstrated, while DFT calculations explain the electronic structure.

Beyond the Oxo‐Wall: Synthesis and Reactivity of a Six‐Coordinate Formally CoIV‐Oxo Complex
Angewandte Chemie, EarlyView.We present the first example of a six‐coordinate formally Co(IV)‐oxo complex, [Co(TQA)(O)(OH)]+ (1), which exists as an admixture of CoIV‐oxo and CoIII‐oxyl resonance structures. Complex 1 is capable of performing oxygen atom transfer reactions and abstracting moderately strong hydrogen atoms at rates faster than other characterized CoIV‐oxo compounds.

Experimental Study on Hypochlorous Acid Blocking the Marine Diatom Adhesion
International Journal of Electrochemical Science, 2012 We investigated the effect of hypochlorous acid (HOCl) on biofouling diatom adhesion by using sea-water antifouling electrolysis method. Results revealed that the diatom killing effect of HOCl generated by electrolysis device was positively correlated ...

Advanced Science, EarlyView.ABSTRACT Methane's efficient catalytic removal is vital for sustainable development. Bimetallic catalysts, though promising for methane activation, pose a design challenge due to their complex compositional space. This work introduces an integrated framework that combines high‐throughput density functional theory (DFT) and interpretable machine ...

Reconstruction of Holocene sea-levels using diatom- and pollen-based microfossil transfer functions, west coast of Scotland, UK [PDF]
, 2007 Due to its sensitivity to isostatic and eustatic sea-level change the west coast of Scotland has been an important area for studying sea-level change. Recently, data from north west Scotland have been used to refine GIA models because of the presence of ...
