Efficient NiOx Hole Transport Layers Enabled by Multifunctional MXenes for High‐Performance Tin‐Lead Perovskite Solar Cells

Advanced Functional Materials, EarlyView.
An efficient NiOx HTL is successfully prepared by introducing MXene as an additive without further surface modification to fabricate high‐performance FASn0.5Pb0.5I3 perovskite solar cells. The introduction of MXene contributes to improved conductivity of NiOx, better aligned at NiOx/perovskite interfaces, and enhanced quality of perovskite films ...

Environmental factors other than iodine deficiency in the pathogenesis of endemic goiter in the basin of river Ganga and Bay of Bengal, India

BLDE University Journal of Health Sciences, 2016
Background: In iodine-replete basin of the river Ganga and the Bay of Bengal, we studied iodine nutritional status of school children by goiter prevalence and their urinary iodine (UI), iodine content in edible salt, and the bioavailability of iodine ...

Amyloidogenic Peptide Fragments Designed From Bacterial Collagen‐like Proteins Form Hydrogel

Advanced Functional Materials, EarlyView.
This study identified amyloidogenic sequence motifs in bacterial collagen‐like proteins and exploited these to design peptides that self‐assemble into β‐sheet fibers and form hydrogels. One hydrogel supported healthy fibroblast growth, showing promise for biocompatible materials. Our work demonstrates that bacterial sequences can be harnessed to create

Nonheme Fe Enzyme‐Catalyzed Enantiodivergent Nitrogen Migration: Directed Evolution and Computational Study of Isopenicillin N Synthases for Biocatalytic Synthesis of Arylglycines

Angewandte Chemie, EarlyView.
Nonheme Fe enzyme isopenicillin N synthase was reprogrammed and evolved as an efficient nitrogen migratase IPNSNim, converting diverse azanyl esters to valuable l‐arylglycines with up to 16 000 TTN and 97:3 e.r. IPNSNim and ACCONim allowed enantiodivergent preparation of both l‐ and d‐arylglycines.

Performance Constraints of All‐Perovskite Tandem Solar Cells in Low‐Intensity, Low‐Temperature Environments

Advanced Materials, EarlyView.
All‐perovskite tandem solar cells are evaluated under low‐intensity and low‐temperature (LILT) conditions relevant to space environments. Distinct loss regimes emerge, where weaker entropic mixing causes halide segragation below ≈240 K going along with a strong current imbalance, while poor electron transport in C60 dominates.

Predictive, Data‐Driven Design of Red‐Light Photoredox Catalysts for C─Heteroatom Bond Formation

Angewandte Chemie, EarlyView.
From redox numbers to red light: Donor oxidation and core reduction potentials predict E0‐0 in cyanoarene dyes, guiding selection of an efficient red‐light catalyst, 4MeODPATPN (PC13). Under 620 nm light, PC13 facilitates Ni‐catalyzed C─heteroatom cross‐couplings (C─N, C─O, C─S) with high functional‐group tolerance and reduced hydrodehalogenation ...

Negative association between serum parathyroid hormone levels and urinary perchlorate, nitrate, and thiocyanate concentrations in U.S. adults: the National Health and Nutrition Examination Survey 2005-2006. [PDF]

PLoS ONE, 2014
Perchlorate, nitrate, and thiocyanate are well-known inhibitors of the sodium-iodide symporter and may disrupt thyroid function. This exploratory study investigated the association among urinary perchlorate, nitrate, and thiocyanate concentrations and ...
