Dynamic Regulation of Supramolecular Chirality in an Amphiphilic Dimeric Macrocycle Through Azobenzene‐Based Photoisomerization

open access: yesAdvanced Science, EarlyView.
A stimuli‐responsive supramolecular system has been rationally designed enabling hierarchical control over supramolecular handedness. This hybrid architecture retains orthogonal host‐guest properties and displays unique amphiphilicity‐directed chiral self‐assembly.

An assessment of fluid flow and overpressure modelling m selected North Sea and Laramide basins [PDF]

open access: yes, 1994
The occurrence of overpressure observed in petroleum bearing basins must be understood in terms of generation and distribution in order to build up a fluid flow history.

Electroreduction of Carbon Dioxide into Selective Hydrocarbon Using Isomorphic Atomic Substitution in Stable Copper Oxide

open access: yes, 2019
The conversion of carbon dioxide into selective hydrocarbons is vital for green energy generation. Due to the chemical instability and lower activity, environmentally stable transition metal oxides (e.g.

Reaction‐Induced Reversible Reconstruction Enhanced Ni‐MgO/CaO Dual Functional Material for Stable CO2 Capture and In Situ Conversion

open access: yesAdvanced Science, EarlyView.
A highly dispersed NiO‐MgO solid solution (MgxNi1‐xO) is created in a hierarchically porous Ca‐based matrix to protect Ni and CaO nanoparticles against carbon deposition and sintering. Owing to the reversible reconstruction of MgxNi1‐xO, this superior structure is self‐regenerative in the calcium looping dry reforming of methane process, thereby ...

Comprehensive Study of the Efficiency of Low-Concentration Nanoemulsions with Diesel Fuel for Enhanced Oil Recovery

open access: yesColloids and Interfaces
This article presents the results of experimental studies examining the effectiveness of low-concentration nanoemulsions for enhanced oil recovery (EOR). The maximum volume concentration of diesel fuel in the emulsions did not exceed 1% by volume.
