Insertion of the FeB cofactor in cNORs lacking metal inserting chaperones

FEBS Letters, Volume 599, Issue 9, Page 1269-1284, May 2025.
Nitric oxide reductase is an enzyme found in the bacterial denitrification pathway. The NOR active site contains a non‐heme iron, often, but not always inserted with the assistance of chaperones. Here, we study the insertion of FeB in the subfamily of cNORs lacking chaperones and found a putative channel, conserved in the family, perhaps enabling the ...

Onshore hydrogen production from boil-off gas (BOG) via natural gas steam reforming process: Process simulation and techno-economic analysis

International Journal of Hydrogen Energy
Growing demand for cleaner energy resources has led to the increased global production of liquefied natural gas (LNG). At the same time, there are some economic and environmental impacts from LNG evaporation forming the boil-off gas (BOG) during production, storage, loading, transportation, and unloading.

Total Synthesis of the Membrane Spanning Tetraether Lipid brGDGT Ia and Elucidation of Its Stereochemical Configuration

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.

Process design and economic optimization of boil-off-gas re-liquefaction systems for LNG carriers [PDF]

, 2019
Recent LNG carriers are equipped with high pressure gas injection engines. However, there has been a lack of research on liquefaction processes for boil-off gas (BOG) on LNG ships driven by high pressure fuel.

We are storytelling apes: Experimenting with new scientific narratives in a time of climate and biodiversity collapse

People and Nature, Volume 7, Issue 5, Page 1257-1268, May 2025.
Abstract Provoked by a lack of appropriate political action on the global climate and biodiversity crisis, we present a perspective advocating and demonstrating a new plurality in scientific communication methods. Science writing, in being objective and dispassionate, actively seeks to mask empathetic connection and hides curiosities that may exist ...

Unearthing the shadows of history: Chemical traces of Second World War atrocities in the Szpęgawski Forest and Death Valley, Poland

Archaeometry, Volume 67, Issue 2, Page 424-438, April 2025.
Abstract This article presents the results of analyses of the chemical composition of organic matter and the occurrence of characteristic geochemical and biochemical markers in 17 samples collected from the Second World War mass graves excavated in the Szpęgawski Forest and Death Valley, Poland. The results show that attempts to cover up mass crimes by

Analytical solutions for the isobaric evaporation of pure cryogens in storage tanks [PDF]

, 2019
New analytical solutions have been derived for the isobaric evaporation of a pure liquid cryogen. In particular, expressions have been provided for the liquid volume, evaporation rate, Boil-off-Gas (BOG) rate, vapour temperature and vapour to liquid heat

Cosmetic emulsions containing innovative complex coacervates: A cross‐sectional study

International Journal of Cosmetic Science, Volume 47, Issue 2, Page 383-397, April 2025.
This study demonstrates the successful encapsulation of α‐tocopherol using non‐animal biopolymers, improving its stability and functional properties in cosmetic emulsions. The developed microcapsules enhance product texture and rheological behaviour, offering promising potential for more stable and functional skincare formulations.

Dynamic modeling of hydrogen production from boil-off gas (BOG) at onshore LNG facilities: Technical and socio-economic analysis

International Journal of Hydrogen Energy
Integrating hydrogen (H2) production systems within natural gas (NG) supply chains can support smoothening transition to cleaner energy resources by utilizing existing infrastructures. This work investigates the dynamic conversion of boil-off gas (BOG) using steam methane reforming (SMR) to produce H2 within liquified natural gas (LNG) process.

The Mesolithic Hunter–Gatherer Camp Site at Sammakko in Norrbotten, Northernmost Sweden—Archeological Finds and Palaeoenvironmental Reconstruction

Geoarchaeology, Volume 40, Issue 1, January/February 2025.
ABSTRACT A small Mesolithic camp site near Sammakko in northernmost Sweden has been identified through its abundance of burnt bone and quartz refuse from stone tool manufacturing/maintenance. Radiocarbon dating places hunter–gatherer activity here around 8900 years ago, 1800 years later than the oldest known settlement in Norrbotten, the Aareavaara ...
