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 ...

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.

Floating storage and regasification units face specific LNG rollover challenges: Consideration of saturated vapor pressure provides insight and mitigation options

Natural Gas Industry B, 2018
Floating Storage and Regasification Units (FSRU) form a rapidly expanding sector of LNG business. In many cases, FSRU now provide a more cost-effective and very flexible way to deliver natural gas to end users in comparison with shore-based terminals ...

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 ...

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.

Problem of Boil - off in LNG Supply Chain [PDF]

, 2013
This paper examines the problem of evaporation of Liquefied Natural Gas (LNG) occurring at different places in the LNG supply chain. Evaporation losses in the LNG supply chain are one of the key factors for LNG safety, technical and economic assessment ...

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

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.

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.
