Ball‐Milling Assisted Synthesis of Monofluoroalkenes
Chemistry – A European Journal, Volume 31, Issue 20, April 4, 2025.A mechanochemical Horner‐Wadsworth‐Emmons reaction enabled the formation of monofluoroalkenes with yields up to 99 %. The solid‐state reaction condition allowed the formation of a broad scope of trisubstituted and tetrasubstituted fluorinated alkenes (48 examples) with the use of a weak base and a short reaction time from aldehydes of ketones. Moreover,

Chemistry – A European Journal, Volume 31, Issue 19, April 1, 2025.The simulants of the toxic and persistent blister agent sulfur mustard (CEES) and organophosphorous nerve agent VX (PhX) are neutralized with high selectivity by peracetic acid under batch and flow conditions. The hazardous peracetic acid is safely generated ‘on demand’ from AcOEt and aq. H2O2, assisted by the supported lipase CALB. Abstract The sulfur‐

Experimental implementation of finite-time Carnot cycle [PDF]
arXiv, 2022 The Carnot cycle is a prototype of ideal heat engine to draw mechanical energy from the heat flux between two thermal baths with the maximum efficiency, dubbed as the Carnot efficiency $\eta_{\mathrm{C}}$. Such efficiency can only be reached by thermodynamical equilibrium processes with infinite time, accompanied unavoidably with vanishing power ...

Dimensionality and geometry effects on a quantum carnot engine efficiency
Revista de Ciencias Tecnológicas, 2019 We calculate the efficiency of a quantum Carnot cycle for a particle confined in two different infinite potential wells, a cylindrical potential well of variable radius and a two-dimensional square potential well with a periodicity in one of it sides. We

Dissipative heat engine is thermodynamically inconsistent
, 2009 A heat engine operating on the basis of the Carnot cycle is considered, where the mechanical work performed is dissipated within the engine at the temperature of the warmer isotherm and the resulting heat is added to the engine together with an external ...

Approaching an Efficient and Feasible Carnot Engine by Carnot Cycle Analysis
Journal of Energy Research and Reviews, 2021 Based on the knowledge exhibited in the literature on the Carnot cycle, a preliminary study is carried out on Carnot machines capable of implementing the Carnot cycle at high thermal efficiency. Therefore, two engine structures are proposed: (i) reciprocating single and double-acting cylinder-based thermal engines implemented under a closed processes ...

FISH, a new tool for in situ preservation of RNA in tissues of deep‐sea mobile fauna
Limnology and Oceanography: Methods, Volume 23, Issue 4, Page 273-292, April 2025.ABSTRACT Accessing the metabolic functioning of deep‐sea animals in situ remains a technological challenge as the recovery time of samples is incompatible with the short lifespan of such molecules as mRNAs. Tools able to preserve RNA in situ exist, but they are incompatible with the study of mobile fauna.
