Cysteine Thioaldehydes: Photolytic Generation, Reactivity, and Biological Implications

open access: yesAngewandte Chemie, Volume 138, Issue 41, 5 October 2026.
Photolysis of cysteine phenacylsulfides bearing non‐conjugating electron‐withdrawing substituents leads to high conversions into cysteine thioaldehydes through a Norrish type‐II pathway. This methodology enabled the study of the aqueous reactivity of these important biosynthetic intermediates, which, depending on peptide sequence, pH and buffer ...

The Impact of Different Phosphorus Fertilizers Varieties on Yield under Wheat–Maize Rotation Conditions

open access: yesAgronomy
The global phosphate (P) rock shortage has become a significant challenge. Furthermore, the misalignment between crops, soil, and P usage exacerbates P rock wastage in agriculture.

Growth of Single Crystals of Ammonium Dihydrogen Phosphate

open access: yesThe Journal of the Society of Chemical Industry, Japan, 1957
リン酸-アンモニウム単結晶を回転法によって成長させ,錐面および柱面の成長量を測定して成長速度を算出し,これと過飽和度および成長温度との関係を求めた。次に種々のpHの溶液,ならびに種々の不純物を添加した溶液を用い,一定温度,一定過飽和度のもとに結晶を成長させて成長速度を求め,それらの影響をしらべた。その結果,定性的に知られていたpHの増加とともに柱面の成長は速くなるという関係が定量化され,同時に錐面の成長速度はpH3.8付近で最大となることが明らかにされた。柱面の成長を抑制してテーパーをつける物質として知られているもののうち,Sn4+,Cr3+,Fe3+,Al3+のそれぞれの濃度と成長速度との関係を求め,さらに柱面の成長を抑制する不純物として,ピロアンチモン酸,モリブデン酸,タングステン酸を見出した ...

Adding Ammonium through Automated pH Control in Zero-discharge Liquid Hydroponics to Maintain Low, Steady-state Concentrations

open access: yesHortScience
Low concentrations of ammonium in hydroponic solutions typically improve plant growth and better simulate field conditions, but it is challenging to achieve steady-state levels because ammonium uptake is several orders of magnitude faster than nitrate ...
