H2‐dependent modulation of tetrahydromethanopterin S‐methyltransferase (Mtr complex) activity by the small protein MtrR in Methanosarcina mazei

The FEBS Journal, EarlyView.
Small protein MtrR is a regulator of the Mtr methyltransferase complex in Methanosarcina mazei. It binds specifically to the MtrA subunit and modulates Mtr activity in response to hydrogen (H2) availability. Deleting mtrR impairs growth in the presence but not absence of H2, indicating its role in directing methyl transfer toward an energy‐conserving ...

Investigation into the delivery and evaluation of a unique Avena sativa (Oat) Lipid Extract on skin barrier using LC‒MS/MS, Raman spectroscopy, immunostaining analysis and skin efficacy

International Journal of Cosmetic Science, EarlyView.
Abstract Objectives Oat lipids are rich in ceramides. In this investigation, we analysed the delivery of a specific Oat Lipid Extract derived from Avena sativa, comprising ‘skin identical’ ratios of fatty acids, ceramides and cholesterol/sterol. This investigation is the first reported investigation of oat lipids utilizing Raman spectroscopy for the ...

Rapid Microwave Annealing of Perovskites: Effects on Device and Material Stability in High Humidity

EcoMat, Volume 8, Issue 3, March 2026.
This study demonstrates that microwave annealing significantly improves the stability of perovskite solar cells when exposed to high humidity conditions. Compared to traditional hot‐plate methods, microwave processing promotes the development of larger crystal grains, thereby obstructing moisture ingress and delaying degradation.
