Enhanced Fenton-like catalytic activity and stability of g-CN nanosheet-wrapped copper phosphide with strong anti-interference ability: Kinetics and mechanistic study.

Metal-based Fenton-like catalysts usually activate HO to produce free radicals (OH and O) for the degradation of organic pollutants. However, a catalytic reaction dominated by free radicals is easily interfered with by various inorganic anions and water matrices. Herein, g-CN-wrapped copper phosphide (CuP), as a highly efficient Fenton-like catalyst, was successfully synthesized by a simple low-temperature phosphidation method.

Firmness evaluation of melon using its vibration characteristic and finite element analysis.

The "Huang gua" melons were measured for their physical properties including firmness and static elastic modulus. The vibrational characteristics of fruits and vegetables are governed by their elastic modulus (firmness), mass, and geometry. Therefore, it is possible to evaluate firmness of fruits and vegetables based on their vibrational characteristics.
