Rose-Inspired Adhesive Surface Regulation for Enhanced Fog Water Collection Efficiency and Self-Cleaning.

Inspired by the adhesion differences on the surfaces of fresh and dried rose petals, a rose bionic self-cleaning fog collector (RBSC) was designed and prepared to realize a self-driven fog harvesting function. The droplet detachment iteration rate was revealed by the regulating mechanism of the surface adhesion force of the RBSC and the influence of bionic texture parameters, as demonstrated through the fog harvesting experiment and droplet detachment failure analysis. Through the surface adhesion force regulation, the probability of droplet dissipation with the airflow is reduced by increasing the falling droplets' mass, and the single surface fog capture efficiency is up to 740 mg cm h.

Rapid detection of sludge moisture content based on the frequency domain reflection.

The moisture content (MC) of sludge is a critical factor affecting sludge treatment and disposal technologies. Traditional drying methods for measuring sludge MC are time-consuming and lack of portability. To achieve rapid online detection of sludge MC, this paper proposes a method based on frequency domain reflectometry.

Antenna-based optimization of triplet radioluminescence of Tb-organic complex scintillator for efficient X-ray detection.

Triplet exciton is both a luminescence quenching factor and an important luminescence sensitization technology solution, which is widely concerned in the field of optoelectronic materials. Since X-ray excited triplet excitons are dissipated through various pathways, there are still huge difficulties in achieving efficient triplet sensitized emission. Here, the antenna ligand is regulated through the carboxyl group, increasing the steric hindrance between the conjugated groups and improving triplet-enhanced radioluminescence (RL) efficiencies of Tb.

Surface Protection Technology for Metallic Materials in Marine Environments.

As the demand for the development and utilization of marine resources continues to strengthen, the service requirements for advanced marine equipment are rapidly increasing. Surface protection technology has become an important way of solving the tribological problems of extreme operating conditions and improving the safety performance of equipment by imparting certain special properties to the surface of the material through physical, chemical or mechanical processes to enhance the ability of the material to withstand external environmental factors. Combined with the extremely complex characteristics of the marine environment, this paper describes the commonly used surface protection technologies for metal materials in the marine environment.

Coupling mechanism and parameter optimization of sewage sludge dewatering jointly assisted by electric field and mechanical pressure.

Pressurized electro-dewatering technology is considered to be one of the most effective methods for improving dewatering performance of sewage sludge. In this paper, four dewatering protocols were developed to further explore the coupling mechanism of sludge dewatering through mechanical pressure, electric field and their joint. The results showed that the dewatering performance of the four dewatering protocols were as follows: pressurized electro-dewatering with constant voltage gradient mode (G-PEDW) > first mechanical dewatering then electro-dewatering > mechanical dewatering > electro-dewatering.
