A review of β-cyclodextrin-based catalysts system in the chemical fixation of carbon dioxide

open access: yesJournal of CO2 Utilization
Carbon fixation is a vital chemical and biological methodology where carbon dioxide (CO2) from the environment is altered into organic materials. This process creates the basis of the carbon cycle.

Liver organoids: modelling complexity in homeostasis and disease

open access: yesFEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Synthesis of 6-membered cyclic carbonates from 1,3-diols and low CO2 pressure: a novel mild strategy to replace phosgene reagents† [PDF]

open access: yesRSC Advances, 2015
Low pressure carbon dioxide is used as the carbonation agent in a simple, safe and efficient procedure for the synthesis of 6-membered cyclic carbonates from 1,3-diols.

Partial depletion of plasminogen activator inhibitor‐1 decreases subcutaneous fat cell hypertrophy and liver cholesterol in high‐fat‐fed female mice

open access: yesFEBS Letters, EarlyView.
Obesity raises blood levels of PAI‐1, a protein linked to metabolic dysfunction‐associated steatotic liver disease in people with obesity. In female mice fed a high‐fat diet, partially lowering PAI‐1 led to smaller subcutaneous fat cells and lower liver cholesterol, without changing body weight or insulin sensitivity.

Nanoporous Copper for the Electrosynthesis of Cyclic Carbonates from CO2 and Epoxides

open access: yesChemElectroChem
Cyclic carbonates are often produced through catalytic coupling reactions of CO2 with epoxides under harsh conditions. Here, we present a highly active nanoporous copper (np‐Cu) cathode material for the electrosynthesis of cyclic carbonates in mild ...

Synthesis of Functionalized Cyclic Carbonates through Commodity Polymer Upcycling

open access: yes, 2020
Functionalized cyclic carbonates are attractive monomers for the synthesis of innovative polycarbonates or polyurethanes for various applications. Even though their synthesis has been intensively investigated, doing so in a sustainable and efficient ...

Structures of mycobacterial 3‐methylcrotonyl‐CoA carboxylase reveal carrier‐domain translocation between catalytic sites

open access: yesFEBS Letters, EarlyView.
Mycobacterial 3‐methylcrotonyl‐CoA carboxylase uses a mobile biotin‐carrying domain to shuttle a carboxyl group between two catalytic sites, enabling carboxylation of 3‐methylcrotonyl‐CoA during leucine breakdown. Cryo‐electron microscopy captures the carrier at both sites and reveals an inward loop movement that may prevent futile rebinding to the ...

Diversity in cyclic carbonates : Synthesis of triazole-functional monomers using click chemistry

open access: yes, 2012
Triazole-functional cyclic carbonates are presented as a new class of functional monomers for ring-opening polymerisation. Starting from bromo-functional six-membered cyclic carbonates, a series of triazole-functional monomers was synthesised using click

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

open access: yesFEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.
