Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)

Angewandte Chemie, EarlyView.
Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

Anion‐Cation Synergistic Passivation for High‐Performance FA‐Cs Halide Perovskite Photodetectors

Advanced Electronic Materials, EarlyView.
An anion‐cation synergistic passivation strategy is developed to improve perovskite photodetectors. Surface‐localized DMePDA2+ cations and bulk‐diffused Cl− anions simultaneously reduce defects, enhancing charge transport and suppressing recombination.

Bromide–Borate Coupling Enables Selective Electrochemical Oxidation of Glycerol to Dihydroxyacetone

Angewandte Chemie, EarlyView.
Bromide–borate coupling enables selective electrochemical upgrading of glycerol to dihydroxyacetone (DHA). Electrogenerated bromine species mediate glycerol oxidation, while borate coordination biases selectivity toward DHA, enabling carbon‐balanced oxidation and high productivity in flow‐cell operation.

Eco‐Friendly Laser‐Induced Graphene/Perovskite Hybrids for Eco‐Friendly Photodetectors

Advanced Electronic Materials, EarlyView.
A sustainable paper‐based photodetector was developed by combining laser‐induced graphene (LIG) with MAPbI3 perovskite. Compared with pure LIG devices, the hybrid photodetector exhibited nearly 10‐fold higher responsivity and 7‐fold greater detectivity while maintaining stable performance after 1000 bending cycles, demonstrating its potential for ...

HUBUNGAN KANDUNGAN IODIUM DALAM AIR TANAH TERHADAP KETINGGIAN TEMPAT DI LERENG BARAT GUNUNG MERAPI

Media Gizi Mikro Indonesia, 2013
Iodine is important element for human growth and development. Lack or excess of this element result human health problems. Naturally, low dietary supply of iodine is primary cause of iodine deficiency, typically in lack iodine environments ..

Using MIS Thermally Stimulated Currents for Degradation Dependent Energetic Landscape Evaluation in Triple Cation Mixed Halide Perovskites

Advanced Energy Materials, EarlyView.
A state‐of‐the‐art triple cation mixed halide perovskite is characterized using thermally stimulated currents in a MIS device architecture. This enables the separate detection of densities of electron and hole states and their activation energies on the same device, unveiling defect state evolution under the degrading influence of ambient conditions ...

Radical, Not Ionic: The Mechanochemical Zincke Nitration of Phenols

Angewandte Chemie, EarlyView.
Mechanochemistry recasts the classical Zincke nitration as an open‐shell process. Liquid‐assisted vibrational milling of phenols with in situ HNO2 delivers direct and ipso nitration across 50 substrates, while atmosphere, NOx‐transfer, EPR and DFT evidence expose a phenoxyl‐radical/NO2 manifold underlying this historically ionic transformation ...

[Salt iodination and excessive iodine intake among schoolchildren].

Archivos latinoamericanos de nutricion, 2011
The objective of the present study was to evaluate the urinary excretion of iodine and relate it to the amount present in salt for human consumption. The study involved 145 children from two schools: a rural one and an urban one. We performed anthropometric measurements and collected a urine sample and a kitchen salt sample from each child.
