Design, Synthesis and Characterization of Novel Arylamides Containing 1,2,4-triazole Nuclei for Possible Antimicrobial Activity

open access: yesE-Journal of Chemistry, 2004
Diphenyl aceto hydrazide on reaction with carbon disulfide and potassium hydroxide gave potassium α,α-diphenyl acetamido dithiocarbamate, which on cyclisation with hydrazine hydrate yielded key intermediate 3-mercapto-4,N-amino-5-benzhydryl-1,2,4 ...

SUGAR Model-Assisted Analysis of Carbon Allocation and Transformation in Tomato Fruit Under Different Water Along With Potassium Conditions

open access: yesFrontiers in Plant Science, 2020
Carbohydrate concentrations in fruit are closely related to the availability of water and mineral nutrients. Water stress and minerals alter the assimilation, operation, and distribution of carbohydrates, thereby affecting the fruit quality.

1-Nitramino-5-aminotetrazole – A simple accessible highly energetic building block

open access: yesEnergetic Materials Frontiers, 2022
The highly energetic 1-nitrimino-5-aminotetrazole moiety can be obtained by direct nitration of 1,5-diaminotetrazole. The hydroxylammonium, 3,6,7-triamino-[1,2,4]triazolo[4,3-b][1,2,4]triazolium (HTATOT) and potassium derivatives were synthesized in this

Recovery of reactive potassium compounds as chemical agents in wastewaters from KOH-activated carbon production

open access: yesCarbon letters
Chemical activation consumes copious quantities of chemicals is therefore hampered by its low economic feasibility. However, this issue can be overcome through the recovery and reuse of alkali compounds leached into wastewater.

Thermochemistry of yavapaiite KFe(SO4)2: Formation and decomposition [PDF]

open access: yes, 2005
Yavapaiite, KFe(SO4)2, is a rare mineral in nature, but its structure is considered as a reference for many synthetic compounds in the alum supergroup. Several authors mention the formation of yavapaiite by heating potassium jarosite above ca. 400°C.

Сardioprotective agents with biaromatic structure. Part 5. Potassium Kv1.5-channels blockers

open access: yesФармакокинетика и Фармакодинамика, 2023
The Kv1.5 potassium channel provides an ultra-rapid delayed rectifier potassium current, IKur, that acts selectively in human atrial cells. This makes selective Kv1.5 blockade a promising approach to control atrial arrhythmias without the adverse ...

Polarizing ³He by Spin Exchange with Potassium [PDF]

open access: yes, 2004
We present experimental studies on the spin-exchange optical pumping of ³He using alkali metal potassium vapor. High ³He polarizations are achieved using lower laser power than traditional rubidium-³He pumping studies.
