Pan-Arctic seasonal cycles and long-term trends of aerosol properties from ten observatories

Even though the Arctic is remote, aerosol properties observed there are strongly influenced by anthropogenic emissions from outside the Arctic. This is particularly true for the so-called Arctic haze season (January through April). In summer (June through ...

Cavity-assisted preparation and detection of a unitary Fermi gas

Jean-Philippe Brantut, Victor Youri Helson, Kevin Etienne Robert Roux, Hideki Konishi

We report on the fast production and weakly destructive detection of a Fermi gas with tunable interactions in a high finesse cavity. The cavity is used both with far off-resonant light to create a deep optical dipole trap, and with near-resonant light to r ...

A Two Step Postsynthetic Modification Strategy: Appending Short Chain Polyamines to Zn-NH2-BDC MOF for Enhanced CO2 Adsorption

Wendy Lee Queen, Jordi Espin Marti, Mehrdad Asgari, Olga Trukhina, Ilia Kochetygov, Anita Justin

Functionalizing metal–organic frameworks (MOFs) with amines is a commonly used strategy to enhance their performance in CO2 capture applications. As such, in this work, a two-step strategy to covalently functionalize NH2-containing MOFs with short chain po ...

Temporary pause in the growth of atmospheric ethane and propane in 2015–2018

Hélène Paule Angot, Ilann Ernest Valentin Bourgeois

Atmospheric non-methane hydrocarbons (NMHCs) play an important role in the formation of secondary organic aerosols and ozone. After a multidecadal global decline in atmospheric mole fractions of ethane and propane – the most abundant atmospheric NMHCs – pr ...

Options to correct local turbulent flux measurements for large-scale fluxes using an approach based on large-eddy simulation

Peter Andreas Brugger

The eddy-covariance method provides the most direct estimates for fluxes between ecosystems and the atmosphere. However, dispersive fluxes can occur in the presence of secondary circulations, which can inherently not be captured by such single-tower measur ...

Magic Walls

Andrew James Sonta

Reducing energy demand on buildings’ heating and cooling systems is fundamental to reaching a carbon-neutral future. Writing in iScience, Xu and Raman show that by controlling radiative heat flows in buildings with novel materials, we can expand the set of ...

Hybrid membranes for energy-efficient carbon capture

Kumar Varoon Agrawal, Guangwei He

Gas separation membrane comprising a porous support onto which is deposited a nanoporous single-layer graphene film with a CO2-philic polymer film having a thickness of 5-100 nm coated on top of graphene nanopores, acting as a CO2-selective film, wherein t ...

In Silico Discovery of Covalent Organic Frameworks for Carbon Capture

Berend Smit, Daniele Ongari, Christoph Leopold Talirz, Aliaksandr Yakutovich, Johanna Maria Huck, Kathryn Suzanne Deeg, Daiane Damasceno Borges, Nakul Rampal

We screen a database of more than 69 000 hypothetical covalent organic frameworks (COFs) for carbon capture using parasitic energy as a metric. To compute CO2-framework interactions in molecular simulations, we develop a genetic algorithm to tune the charg ...
