Distribution of natural radionuclide40K in biotic and abiotic components of the Cauvery river system, Tiruchirapalli, India

open access: yesJournal of Biosciences, 1992
Abiotic components like water and sediment, and biotic components such as mussels, fish and grass collected from Cauvery river at Tiruchirapalli were analysed for40K activity. The highest level of40K activity was found in the sediment (342 mBq g-1 dry weight) and the lowest activity was found in water (2·209 mBq ml−1). In the freshwater musselParreysia

Flame‐Retardant Ionogel Enabled by Lignin Molecular Networks for Fire Rescue

open access: yesAdvanced Science, EarlyView.
Wearable sensors for harsh, high‐temperature, fire‐prone environments face challenges in heat resistance and stability. This study introduces a flame‐retardant, waterproof glycol lignin ionogel (GLI) with a robust 3D network, exceptional tensile strength, strong adhesion, biocompatibility, eco‐safety, and dual temperature‐motion sensing, even after ...

Heme/NADH Mimics Co‐Decorated Allosteric Capsules for Regulating Oxygen Activation and Upregulating Intracellular Methionine Depletion

open access: yesAdvanced Science, EarlyView.
Through modifying the switchable µ‐oxo bridged FeIII‐porphyrins moiety and NADH mimics into a metal‐organic capsule, multiple responsive manners for O2 activation, chemical oxygenation and metabolic transformation have been demonstrated for upregulating intracellular methionine depletion and accumulation of methionine sulfoxide to achieve effective ...

Influence of some environmental variables on the diversity and distribution of aquatic oligochaetes (Clitellata: Annelida) in the Nyong estuary (Atlantic coast, southern Cameroon)

open access: yesScientific African
Tropical estuarine ecosystems are subject to strong anthropogenic pressures, with the direct consequence of declining or lost biodiversity. An essential and little-known biological component of these estuarine ecosystems is the population of oligochaete ...

Benefit from Biomass Boiler Emissions to Increase Greenhouse CO2 Levels for Optimal Growth and Yield in Tomato, Cucumber, and Strawberry

open access: yesAdvanced Energy and Sustainability Research, EarlyView.
Using CO2‐rich polluting gases in greenhouse plant cultivation has proven to be a promising technique for stimulating plants while reducing emissions to the atmosphere. The use of an experimental biofilter proves to be effective in retaining most of the toxic particles. The alteration of physiological and metabolic parameters shows an adaptation of the
