Direct synthesis of extra-heavy olefins from carbon monoxide and water

open access: yesNature Communications, 2023
Fischer-Tropsch synthesis is challenged by the trade-off between enhancing C-C coupling and suppressing further hydrogenation of olefins. Here the authors break this challenge by developing a universal strategy to synthesis extra-heavy olefins from ...

Effect of Temperature on the Dynamic Properties of Mixed Surfactant Adsorbed Layers at the Water/Hexane Interface under Low-Gravity Conditions

open access: yesColloids and Interfaces, 2020
An increase in temperature typically leads to a decrease in the interfacial tension of a water/oil interface. The addition of surfactants to the system can complicate the situation significantly, i.e., the interfacial tension can increase or decrease ...

Facet-dependent electrooxidation of propylene into propylene oxide over Ag3PO4 crystals

open access: yesNature Communications, 2022
The electrooxidation of propylene into propylene oxide is important in many industrial sectors. Here, the authors demonstrate efficient and facet-selective formation of propylene oxide using Ag3PO4 cubes and investigate the reaction mechanism.

An efficient quantum light–matter interface with sub-second lifetime [PDF]

open access: yesNature Photonics, 2015
An efficient light–matter interface for quantum repeaters is developed. By placing Rb atoms optically confined in a 3D lattice in a ring cavity, an initial retrieval efficiency of 76% together with a 1/e lifetime of 0.22 s are achieved.

Tailoring Topological Transitions of Anisotropic Polaritons by Interface Engineering in Biaxial Crystals. [PDF]

open access: yesNano letters (Print), 2022
Polaritons in polar biaxial crystals with extreme anisotropy offer a promising route to manipulate nanoscale light-matter interactions. The dynamic modulation of their dispersion is of great significance for future integrated nano-optics but remains ...

Ambient-pressure hydrogenation of CO2 into long-chain olefins

open access: yesNature Communications, 2022
The conversion of CO2 by renewable power-generated hydrogen is a promising approach to a sustainable production of long-chain olefins. Here the authors report a Cu-Fe catalyst which achieves the hydrogenation of CO2 into long-chain olefins under ambient ...

A spatially resolved timeline of the human maternal–fetal interface

open access: yesNature, 2023
A multiomics approach is used to produce a spatiotemporal atlas of the human maternal–fetal interface in the first half of pregnancy, revealing relationships among gestational age, extravillous trophoblasts and spiral artery remodelling. Beginning in the

Volcano-type relationship between oxidation states and catalytic activity of single-atom catalysts towards hydrogen evolution

open access: yesNature Communications, 2022
While single atom catalysis offers high efficiency for materials use, different possible atomic configurations yield differing activities. Here, authors modulate single-atom Os coordinations to show a volcano relationship between oxidation state and H2 ...

Generating multi-atom entangled W states via light-matter interface based fusion mechanism [PDF]

open access: yesScientific Reports, 2015
W state is a key resource in quantum communication. Fusion technology has been proven to be a good candidate for preparing a large-size W state from two or more small-size W states in linear optical system.
