Intensive research efforts have been made on fluorescent carbon quantum dots (CQDs);
however, it is still a challenge to realize highly emissive solid-state luminescence due to the …

A multifunctional substrate integrated waveguide (SIW) device integrated with multi-state
diplexer (MSD) and multi-channel filtering crossover (MCFC) is proposed in this brief. In …

The development of high-efficiency oxygen reduction reaction (ORR) and oxygen evolution
reaction (OER) dual-function electrocatalysts based on transition metal and nitrogen co-…

The excitation wavelength dependent photoluminescence (PL) of graphene oxide quantum
dots (GOQDs), which is frequently explained by size effects and radiative surface states, has …

This article proposes a novel humidity sensor using a microwave resonant cavity as the
sensing device. This sensor comprises a high-quality factor resonant cavity and frequency …

The existing CO 2 absorption by deep eutectic solvents is limited by the unavoidable water
absorption problem during use. In this study, we prepared three deep eutectic solvents with …

Multimode feed network is a key element in shortwave multimode multi-feed antenna system.
Its effective and precise optimizing design will provide the basis to the entire multimode …

Deep eutectic solvents (DESs) are a new class of green solvents that exhibit unique properties
in various process applications. In this regard, this study evaluated imidazole-type DESs …

In this study, we used tetraethylammonium chloride (TEAC), diethanolamine (DEA), and N-methyldiethanolamine
(MDEA) to prepare ternary DES and binary DES to absorb CO 2 . We …

Sulfidation has been regarded as an effective strategy to enhance the sequestration of
contaminants by zerovalent iron (ZVI). However, the effect of sulfidation on ZVI for V(V) removal …
