👉Vant-Goff Gollandiyaning Rotterdam shahrida nufuzli va ziyoli oilada 1852 yili 30 avgustda dunyoga keldi.
✔️Ikki yil mobaynida Yakob Vant-Goff mashhur olim Fridrix Kekul rahbarligida Bonn shahrida o‘ztkazilgan ilmiy tadqiqotlarda faoliyat yuritdi. Yosh kimyogar ustozi bilan birgalikda propion kislotasini kashf etib, katta yutuqqa erishadi. Hozirgi kunda ushbu kislota ayrim dori vositalarini ishlab chiqarishda keng qo‘llanilib kelinmoqda.
✔️1874-1875 yillari Vant-Goff ilmiy ishlarida o‘tkazilgan tadqiqotlar asosida to‘plangan nazariy va amaliy natijalarni umumlashtirib, kimyoviy jarayonlarni oddiy tenglamalar bilan ifodalab berdi.
✔️Jumladan, termodinamikaning asosi hisoblangan izoxora va izoterma tenglamalarini yaratdi. U harorat ortishi bilan kimyoviy jarayonning tezlashishini aniqladi.
✔️M.Faradey tomonidan elektroliz hodisasining kashf qilinishi bilan elektrokimyoga asos solindi. Uning asosida elektr toki ta’sirida kimyoviy birikma molekulalari alohida moddalar ionlariga ajraladi. Vant-Goff esa o‘zi o‘tkazgan tadqiqodlar asosida bu jarayonelektr tokisiz ham yuz berishi mumkinligini ko‘rsatib berdi.
✔️Bu kashfiyot suyuqliklarda osmotik bosimni o‘rganish jarayonida yuzaga kelgan bo‘lib, bu bosim moddani tashkil etgan atom va molekulalar xususiyatlarini o‘rganishda muhim o‘rin egallaydi hamda shu modda uchun Avagadro qonunini qo‘llash imkonini beradi.
✔️Aynan shu kashfiyotlari uchun Yakob Vant-Goff1901 yili kimyo sohasida Nobel mukofotiga loyiq deb topilgan edi.

Investors took profits on Friday while they could ahead of the weekend, explained Tom Essaye, founder of Sevens Report Research. Saturday and Sunday could easily bring unfortunate news on the war front—and traders would rather be able to sell any recent winnings at Friday’s earlier prices than wait for a potentially lower price at Monday’s open. Founder Pavel Durov says tech is meant to set you free In view of this, the regulator has cautioned investors not to rely on such investment tips / advice received through social media platforms. It has also said investors should exercise utmost caution while taking investment decisions while dealing in the securities market. On February 27th, Durov posted that Channels were becoming a source of unverified information and that the company lacks the ability to check on their veracity. He urged users to be mistrustful of the things shared on Channels, and initially threatened to block the feature in the countries involved for the length of the war, saying that he didn’t want Telegram to be used to aggravate conflict or incite ethnic hatred. He did, however, walk back this plan when it became clear that they had also become a vital communications tool for Ukrainian officials and citizens to help coordinate their resistance and evacuations. The company maintains that it cannot act against individual or group chats, which are “private amongst their participants,” but it will respond to requests in relation to sticker sets, channels and bots which are publicly available. During the invasion of Ukraine, Pavel Durov has wrestled with this issue a lot more prominently than he has before. Channels like Donbass Insider and Bellum Acta, as reported by Foreign Policy, started pumping out pro-Russian propaganda as the invasion began. So much so that the Ukrainian National Security and Defense Council issued a statement labeling which accounts are Russian-backed. Ukrainian officials, in potential violation of the Geneva Convention, have shared imagery of dead and captured Russian soldiers on the platform.
