Peter came to UMass Amherst in 1963, straight from his doctoral work at Harvard, and became a linchpin of the Chemistry Department. He showed the same interest and gave the same level of support to everyone, regardless of their stature. Peter was an amazing combination of keen intellect, boundless curiosity, unlimited generosity, humbleness ...Formula of Joule Thomson Effect. The Joule Thomson effect formula is below. μJT = (∂T/∂P)H. For a gas temperature that is above the inversion temperature, the μJT would be negative. The ∂P shall be always negative in this case, which means that the ∂ must be positive. Consequently, the warming of the gas will take place.

Potassium fluoride (KF) is an ideal reagent for fluorination because it is safe, easy to handle and low-cost. However, poor solubility in organic solvents coupled with limited strategies to control its reactivity has discouraged its use for asymmetric C–F bond formation. Here, we demonstrate that hydrogen bonding phase-transfer catalysis with KF provides access to valuable β-fluoroamines in ...Quantification of rhizodeposition (root exudates and root turnover) represents a major challenge for understanding the links between above‐ground assimilation and below‐ground anoxic decomposition of organic carbon in rice paddy ecosystems.

We are particularly focused on carbon dioxide capture from air and sustainable carbon recycling through a concept called the methanol economy.The description of Thomson’s atomic model is one of the many scientific models of the atom. It was proposed by J.J Thomson in the year 1904 just after the discovery of electrons. However, at that time the atomic nucleus was yet to be discovered. So, he proposed a model on the basis of known properties available at that time.Chemistry – A European Journal showcases fundamental research and topical reviews in all areas of the chemical sciences around the world. ...
