Characterization of drowning by diatom test.

The Indian journal of medical research, 1993
Examination by the diatom test, of different organs of corpses of individuals who died of drowning revealed the presence of frustules in all the visceral organs. Diatom load of different organs was found to be positively related with breadth/diameter of the frustule. Relatively larger diatoms were encountered in the lungs, heart and kidneys as compared

Achievement of Transition Metal Chalcogenides/Oxides in Hydrogen Production by Seawater Electrolysis

EcoEnergy, EarlyView.
Transition metal chalcogenides (TMCs)/oxides have shown great application potential in seawater splitting for hydrogen generation due to their adjustable electronic properties, abundant active sites, and excellent catalytic performance. ABSTRACT Under the impetus of global “dual carbon” goals, green hydrogen has become a key component of the future ...

Diatom test: a reliable tool to assess death by drowning?

International Journal of Research in Medical Sciences, 2016
Background: Post mortem analysis of drowning is a classical problem especially in decomposed bodies recovered from water. One of the important issues in the study of drowning has been the search for a sensitive, specific and easily applicable test for the cause of death.

Co‐Catalyst/Semiconductor Interface Coupling Design for Efficient Solar‐Driven Photocatalysis

EcoEnergy, EarlyView.
Interfacial coupling strength is proposed as a unifying descriptor governing charge‐transfer behavior in co‐catalyst/semiconductor photocatalytic systems. This review establishes a coupling‐strength‐guided framework that correlates interface engineering strategies with charge transport pathways, electronic structure regulation, and photocatalytic ...

Multidimensional Engineering Enabling Rate‐Matched C−N Coupling for Efficient Organonitrogen Electrosynthesis

EcoEnergy, EarlyView.
This review introduces rate matching as a unifying design principle for efficient electrochemical C−N coupling and highlights multidimensional engineering of catalysts, interfaces, and reactors to synchronize the generation of carbon‐ and nitrogen‐containing intermediates, balance their surface coverages, maximize C−N bond formation, and enable ...

Dynamic Reconstruction of Atomically Dispersed Copper Catalysts for CO2 Reduction: From In Situ Observations to Rational Design

EcoEnergy, EarlyView.
Dynamic reconstruction transforms atomically dispersed Cu catalysts into authentic working‐state active phases during CO2 electroreduction. By integrating operando characterization, multiscale simulations, and AI‐assisted predictive modeling, this review establishes a framework for understanding, predicting, and rationally engineering catalyst ...

Estuarine benthic diversity declines with temperature across a tropical–temperate gradient

Ecography, EarlyView.
Estuarine benthic sediments are important habitats that support ecosystem health and productivity, but the drivers of large‐scale patterns in benthic diversity are not well documented. Using 18S amplicon sequencing of 425 sediment DNA samples from estuaries spanning 20° of latitude along Australia's east coast, we assessed tropical–temperate patterns ...

Investigation of diatomaceous sand using elastic and electromagnetic waves in oedometer tests [PDF]

E3S Web of Conferences
The small-strain and electromagnetic behaviors of soils significantly change due to compression. The objective of this study was to investigate the small-strain stiffness and electrical resistivity of diatomaceous sand by modifying the conventional setup
