Toward a Fundamental Understanding of Geological Hydrogen Storage

open access: yesIndustrial & Engineering Chemistry Research, 2022
Geological H2 storage plays a central role to enable the successful transition to the renewable H2 economy and achieve net-zero emission in the atmosphere. Depleted oil and gas reservoirs are already explored with extensive reservoir and operational data. However, residual hydrocarbons can mix with injected H2 in the reservoirs.

Methodological basis of mapping signs of industrial helium concentrations in Ukraine (Dnipro-Donetsk depression)

open access: yesМінеральні ресурси України
Helium is one of the most valuable industrial gases that is not widely distributed in the atmosphere and in the Earth’s crust. The unique physicochemical properties of helium make it indispensable in a wide range of industrial and research areas.

A Novel Modified Petroresin Particle (MPRP) With Enhanced Oil–Water Selectivity for Cold Production in Heavy Oil Reservoirs

open access: yesAdvanced Functional Materials, EarlyView.
A novel oil–water selective conformance control agent, MPRP, is prepared via hydrophilic grafting and mechanical granulation. MPRP uniformly disperses in water, cohesively expands upon aging, and readily dissolves in the oil phase. During conformance control, it selectively aggregates in water channeling pathways to form effective plugs without ...

Sustainable Pd‐Catalyzed Aminations “on Dirty Water”

open access: yesAngewandte Chemie, EarlyView.
Aminations, done safely yet neat, and therefore, quickly, using low levels of Pd, in “dirty water” that must contain 30% KOH; not NaOH, and not at 5%,10%, 20%, 40%, or 50% KOH. Moreover, no base sensitivity of functional groups! Very cool. Thank you, Nature.
