LEGO Group signs long-term deal for Climeworks’ direct air capture carbon removal technology
The LEGO Group has ringfenced $2.4m for carbon removals from direct air capture technology provided by Climeworks, as it strives ahead with efforts to reach net-zero emissions by 2050.

Taking CO2 out of the air would be an absurdly expensive way to fight climate change
Carbon dioxide removal — a suite of technologies aimed at taking CO2 out of the atmosphere — could cost the US hundreds of billions of dollars, a report finds.

The fate of the interstellar medium in early-type galaxies. III. The mechanism of ISM removal and quenching of star formation
Understanding how galaxies quench their star formation is crucial for studies of galaxy evolution. Quenching is related to the cold gas decrease. In the first paper we showed that the dust removal timescale in early-type galaxies (ETGs) is about 2.5 Gyr. Here we present carbon monoxide (CO) and 21 cm hydrogen (H I) line observations of these galaxies and measure the timescale of removal of the cold interstellar medium (ISM). We find that all the cold ISM components (dust, molecular and atomic g…

Facile synthesis of fine-grained CoFe$_2$O$_4$ anchored on porous carbon for simultaneous removal of tetracycline and arsenite
The coexistence of tetracycline (TC) and arsenite (As(III)) in livestock wastewater threatens public health, and the heterogeneous Fenton-like system is a practical approach for the simultaneous removal of TC and As(III). In this work, fine CoFe$_2$O$_4$ nanoparticles are facilely anchored on heretically porous carbon (CoFe$_2$O$_4$@PC) via a microwave-assisted calcination method and used for eliminating TC and As(III) via peroxymonosulfate (PMS) activation.
