Deep eutectic solvents (DESs) have attracted significant attention in recent years due to its environment friendly characteristics and its participation in the multi-heteroatom doping of carbon quantum dots (CQDs). In this work, we present a simple, fast, and environment-friendly microwave synthesis approach for the synthesis of DES-assisted nitrogen and chloride co-doped CQDs (N,Cl-CQDs) using a choline chloride-urea based DES. A biomass-based precursor, i.

This study elucidated the mechanisms involved in the impact of Tsamba (a highland barley product) starch digestibility by different thermal treatments. The results demonstrate that different thermal processing methods (microwave, roasting, sand frying, frying, baking, and steaming) significantly alter the polyphenol content of highland barley, which in turn affects its ability to inhibit α-amylase activity. SEM, CLSM, XRD and FTIR were used to evaluate the effects on starch microstructure and digestibility.

Microwave-assisted evaporation technology is widely used today, but its molecular mechanism is not fully understood. To investigate the molecular mechanism of the influence of microwave electric field direction on water evaporation, this paper designed experiments to measure the microwave energy required to evaporate each gram of water with electric field directions parallel and perpendicular to the water surface. The temperature rise curve of the water is controlled to be consistent in both cases, and the temperature distribution of the water is made uniform by stirring.

The advent of two-dimensional van der Waals materials is a frontier of condensed matter physics and quantum devices. However, characterizing such materials remains challenging due to the limitations of bulk material techniques, necessitating the development of specialized methods. Here, we investigate the superconducting properties of BiSrCaCuO flakes by integrating them with a hybrid superconducting microwave resonator.
