Simulasi Mekanisme Reaksi Pada Siklus Penyimpanan-Pelepasan Hidrogen Berbasis Sistem Bikarbonat-Format Dengan Katalis (4-Me)Triaz(NHPiPr2)2Mn(CO)2Br = Reaction Pathway Simulation Of Hydrogen Storage-Release Cycles Based On Bicarbonate-Formate System (4-Me)Triaz(NHPiPr2)2Mn(CO)2Br Catalyst
" Hidrogen berpotensi besar sebagai energi masa depan, namun untuk metode penyimpanannya yang efektif masih menjadi tantangan. Penyimpanan bentuk gas membutuhkan vessel yang tahan tekanan setinggi 350 bar dan bentuk cair memerlukan suhu dibawah –239,95°C, sehingga butuh insulasi yang sulit. Pada November 2022, tim peneliti dari Jerman, Henrik dkk., mengembangkan metode penyimpanan dan pelepasan hidrogen dengan menggunakan reaksi kesetimbangan bikarbonat-format yang dibantu oleh katalis (4-Me)Triaz(NHPiPr2)2Mn(CO)2Br. Katalis tersebut berbasis mangan yang merupakan logam paling berlimpah kedua di ... "

Modern charge-density analysis
" This book focuses on state-of-the-art methods and applications of electron-density analysis. It is a field traditionally associated with understanding chemical bonding and the electrostatic properties of matter. Recently, it has also been related to predictions of properties and responses of materials (having an organic, inorganic or hybrid nature as in modern materials and bio-science, and used for functional devices or biomaterials) ...
