Coulomb Blockade in low mobility nanometer size Si:MOSFETs

open access: yes, 1999
We investigate coherent transport in Si:MOSFETs with nominal gate lengths 50 to 100nm and various widths at very low temperature. Independent of the geometry, localized states appear when G=e^{2}/h and transport is dominated by resonant tunnelling ...

Expanding the substrate scope of a bacterial monoterpene synthase for the production of sesquiterpenoid and diterpenoid products

open access: yesThe FEBS Journal, EarlyView.
We have converted the only known true bacterial monoterpene synthase, cineole synthase from Streptomyces clavuligerus (bCinS, C10 substrate), to a highly competent sesquiterpene synthase (C15) with a minimum number of rational mutations. By comparison with diterpene synthases (C20), we were then able to bestow diterpene synthase activity on bCinS. This

From External Governance to Energy Diplomacy: The European Pursuit of Green Hydrogen

open access: yesJCMS: Journal of Common Market Studies, EarlyView.
Abstract Following the Russian invasion of Ukraine, the European Union (EU) and its Member States are faced with the double imperative of ensuring energy security whilst reaching decarbonisation goals. A number of authors have suggested that we are observing a geopolitical Commission that is shifting to more active ‘energy diplomacy’, as opposed to its

New knowledge about shock events that affected the L‐chondrite parent body from two heavily shocked L6 meteorite finds

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We report new results from a study of shock‐related features in the L6 ordinary chondrites Northwest Africa (NWA) 4672 and NWA 12841. Our observations confirm the occurrence of eight high‐pressure (HP) minerals in each meteorite, namely, ringwoodite, majorite, akimotoite, wadsleyite, albitic jadeite, lingunite, tuite, and xieite.

Association of Water, Sanitation, Hygiene and Animal Ownership With Relapse to Acute Malnutrition Among Children Aged 6–59 Months in Mali, South Sudan and Somalia: A Multi‐Site Prospective Cohort Study

open access: yesMaternal &Child Nutrition, EarlyView.
Relapse rates post‐SAM treatment varied: 32% in Mali, 63% in South Sudan, 21% in Somalia. Diverse WASH and animal ownership factors were linked to relapse risk, differing by context. Some WASH conditions increased risk, whereas animal ownership was protective in Mali and South Sudan. No significant associations emerged in Somalia.
