Three Birds with One Stone: High‐Performance 2D Lead‐Free Perovskite Solar Cells via Direct In Situ Generation of Organic‐Spacer Precursors

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Adopting a “three birds with one stone” strategy, the in situ generation of organic spacer simultaneously addresses three major challenges limiting 2D tin‐based perovskites: (1) Sn2+ oxidation; (2) rapid crystallization; and (3) uncontrolled 2D phase distribution.

Research Progress of Three‐Terminal Perovskite/Silicon Tandem Solar Cells Based on Back‐Contact Silicon

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Perovskite/silicon tandem solar cells offer efficiencies beyond 30%, yet conventional architectures face trade‐offs between optical performance and current matching. Three‐terminal tandems employing silicon back‐contact bottom cells eliminate the current‐matching constraint while minimizing optical losses, offering superior energy yield under real ...

catena-Poly[[μ2-4,4′-bis(pyridin-3-ylethynyl)-1,1′-biphenyl-κ2N:N′]bis(μ2-thiocyanato-κ2N:S)bis(thiocyanato-κS)dimercury(II)]

IUCrData, 2017
In the title polymer, [Hg2(SCN)4(C26H16N2)]n, the two equivalent HgII atoms are coordinated by one N atom of a bridging 4,4′-bis(pyridin-3-ylethynyl)-1,1′-biphenyl ligand, two S atoms of two thiocyanates and one N atom of a thiocyanate, giving rise to a ...

Regulating secondary phase of Rb‐based aggregates for efficient and stable perovskite solar cells

FlexMat, EarlyView.
By introducing RbAc into the precursor solution, the crystallization pathway is optimized, excessive lead iodide is eliminated, grain size increases, and defects are passivated in the perovskite films. The obtained perovskite devices exhibit improved power conversion efficiency and operational stability. Abstract Passivating defects in perovskite films

Loss of zinc from zinc‐biofortified rice and conventional rice varieties due to various cooking techniques practiced in rural Bangladesh

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Zinc‐biofortified rice has the potential to provide a sustainable solution for zinc deficiency, particularly in Asian countries where rice is the primary staple food. However, cooking of raw rice is associated with some loss of micronutrients, including zinc.

Tiocianato sérico: un marcador bioquímico para discriminar fumadores de no fumadores

Revista Cubana de Higiene y Epidemiología
Se estudiaron 73 personas supuestamente sanas, de ambos sexos y con una edad promedio de 28,55 años con el objetivo de validar la técnica de cuantificación de tiocianato (-SCN) en suero. Se obtuvo que los fumadores tenían concentraciones de -SCN (110,86 ±
