Potential Trophic Competition Between the European Perch Perca fluviatilis and Pikeperch Sander lucioperca

International Review of Hydrobiology, Volume 111, Issue 1, June 2026.
ABSTRACT The European perch Perca fluviatilis and pikeperch Sander lucioperca can co‐occur, potentially competing for food resources. However, few studies have addressed the potential feeding competition between these species. We used carbon and nitrogen stable isotope analysis to assess the potential trophic competition between these species in two ...

Selected Ion Flow-Tube Mass Spectrometry (SIFT-MS) of Mo(CO)₆ and W(CO)₆ Vapours With Positive and Negative Reagent Ions. [PDF]

J Mass Spectrom
ABSTRACT Selected ion flow‐tube mass spectrometry (SIFT‐MS) was used to characterise the gas‐phase ion–molecule reactions of the eight standard reagent ions H3O+, NO+, O2+˙, OH−, O−˙, O2−˙, NO2− and NO3− with molybdenum and tungsten hexacarbonyls, Mo(CO)6 and W(CO)6.

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

δ13C and δ15N Values of Residues Provide Insights Into Identification of the Explosive Source

Rapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Postblast analyses of military and terrorist events will benefit from the capacity to learn more about the explosive materials used in an event. Here stable isotope ratio analyses (δ13C, δ15N) can provide additional information to complement identification of the explosive components.

A critical review of porous adsorbents for air separation: From fundamental insights to rational adsorbent design

AIChE Journal, Volume 72, Issue 4, April 2026.
Abstract Air separation via selective adsorption using porous adsorbents offers energy‐efficient alternatives to cryogenic distillation for producing high‐purity O2 and N2. Adsorbent efficacy depends on balancing selectivity, durability, and performance consistency across varying conditions. This comprehensive review critically discusses the design and

Accessing intractable, phosphorylated intrinsically disordered proteins via a protease‐cleavable inclusion body tag

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Phosphorylated intrinsically disordered proteins (IDPs), such as Bcl2‐associated agonist of cell death (BAD) and Tau, play critical roles in apoptosis and neurodegeneration, yet their instability during recombinant expression due to degradation, aggregation, and dephosphorylation, has limited structural and mechanistic studies.
