Nickel‐Based Cocatalysts on Titanium‐Doped Hematite Empower Direct Photoelectrochemical Valorisation of 5‐Hydroxymethylfurfural

ChemSusChem, EarlyView.
Nickel modified titanium doped hematite photoanode shows a selective hole scavenging for the photoelectrochemical valorisation of the biomass derivative HMF to FDCA, overcoming the competition with water oxidation. Insights on the role of nickel in the HMF oxidation process are achieved with operando x‐ray absorption spectroscopy via element‐selective ...

A Survey of Phase Shifters for Microwave Phased Array Systems

International Journal of Circuit Theory and Applications, EarlyView.
ABSTRACT Phased Array Systems (PASs) are extensively used in radar and telecommunication systems for diverse applications, including military surveillance and wireless broadband communication. Besides, they are becoming increasingly indispensable in modern applications such as multi‐function phased array radars for weather monitoring and aircraft ...

A review of multiscale numerical modeling of rock mechanics and rock engineering

Deep Underground Science and Engineering, EarlyView.
Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

Global artificial light masks biologically important light cycles of animals

Frontiers in Ecology and the Environment, EarlyView.
We document the importance of low‐light conditions in 136 animal species and then translate the new world atlas of skyglow, which reports artificial night sky brightness, into estimates of anthropogenic illuminance (that is, artificial light reaching Earth's surface).
