The hydrogen evolution rate in photoassisteddecomposition of water by Pt/TiO2 was significantly enhanced in the presence of tritium (90–180 mCi/ml). The extent of the enhancement was proportional to the tritium concentration. This effect is attributed to the synergism of β-rays from tritium and photons on this decomposition reaction.
在tri存在下(90-180 mCi / ml),Pt / TiO 2光辅助分解水中的氢释放速率显着提高。增强程度与the浓度成正比。该作用归因于from和光子的β射线在该分解反应中的协同作用。

provisions made for protection against health hazards. The plant is made entirely of glass, the safe thickness of which can be calculated. Details are given of the vacuum system employed. Special manipulations described in the article cover the production and purification of tritium, tritiated water preparation, the preparation of tritium-zirconium targets, and the purification of krypton-8 5 and xenon-133
Enzymatic synthesis of halogen derivatives of L‐phenylalanine and phenylpyruvic acid stereoselectively labeled with hydrogen isotopes in the side chain
Halogenated, labeled with deuterium, tritium or doubly labeled with deuterium and tritium in the 3S position of the side chain isotopomers of L-phenylalanine and phenylpyruvic acid were synthesized. Isotopomers of halogenated L-phenylalanine were obtained by addition of ammonia from isotopically enriched buffer solution to the halogenated derivative of (E)-cinnamic acid catalyzed by phenylalanine ammonia
合成了L-苯丙氨酸和苯丙酮酸侧链同位素异构体的卤化、氘、氚标记或氘、氚双标记。卤代L-苯丙氨酸的同位素异构体是通过将富含同位素的缓冲溶液中的氨加到由苯丙氨酸氨裂合酶催化的( E )-肉桂酸的卤代衍生物中获得的。卤代苯丙酮酸的同位素异构体是通过在苯丙氨酸脱氢酶存在下转化卤代L-苯丙氨酸的适当同位素异构体来酶促获得的。使用氘水作为氘源,使用高度稀释的氚水溶液作为氚源。标记的产率良好,氘原子丰度较高。
