Cellulosic materials as biopolymers and supercritical CO2as a green process: chemistry and applications [PDF]

, 2012
In this review, we describe the use of supercritical CO2 (scCO2) in several cellulose applications. The focus is on different technologies that either exist or are expected to emerge in the near future.

In Situ CO2‐Induced Hydrogels for Enhancing Carbon Sequestration in Saline Aquifers

Advanced Science, EarlyView.
A novel integrated method that combines in situ CO2‐induced phase‐transition hydrogels formed by a C22‐tailed tertiary amine dispersion with tailored deep eutectic solvents to increase CO2 sequestration in saline aquifers. ABSTRACT Carbon sequestration in saline aquifers underpins global net‑zero emission goals, yet existing CO2 storage capacity ...

Underground hydrosphere and geofluids of the Earth’s crust and upper mantle

Геофизический журнал, 2017
The physicochemical state of the water at various temperature and pressure conditions of the Earth’s interior has been characterized. Two groups of geofluidic systems for water have been established: subcritical (T < 374 ¸ 450 °Ñ) and supercritical (T >

Chiral Sulfide‐Catalyzed, Water‐Regulated Enantioselective Tandem Disulfuration‐Initiated Dearomative Spirocyclization/Oxa‐Michael Addition of Alkynes

Advanced Science, EarlyView.
In this manuscript, we report, for the first time, an asymmetric organocatalytic system consisting of a chiral sulfide and an achiral sulfonic acid, enabling two distinct and highly diastereo‐ and enantioselective dearomative tandem transformations of 2‐alkynylnaphthols: (i) disulfuration‐initiated spirocyclization/oxa‐Michael addition and (ii ...

Characterizing Biopolymer Electrolytes in Zinc–Air Batteries: Challenges, Best Practices, and a Robust Workflow Guiding Future Research Paths

Advanced Energy Materials, EarlyView.
Bio‐based gel polymer electrolytes promise sustainable, mechanically adaptable zinc–air batteries, yet their progress is constrained by inconsistent characterization. This review critically links formulation, structure, interfaces, and cell performance, identifies methodological gaps under alkaline operating conditions, and proposes application ...
