Microwave‐sintered mullite structural ceramics based on low‐grade bauxite applied for fracturing proppants

Energy Science &Engineering, Volume 12, Issue 8, Page 3243-3257, August 2024.
This paper investigates the strength characteristics and fracture propagation process of coal and rock under bending load. The evolutionary rules of strain energy for coal and rock were calculated and obtained. The fracture mechanism of coal and rock was discussed by analyzing the critical strain energy release rate. Abstract This study aimed to assess

Electrochemical Behaviour and Sensing of Chlorpromazine at Polymer‐Free Kaolin‐Based Nanosodalite and Nanosodalite‐Graphene Foam Film modified Glassy Carbon Electrodes

ChemElectroChem, Volume 11, Issue 14, July 15, 2024.
A Pure nanosodalite (SOD) was synthesised using natural Cameroonian kaolin and utilised for the preparation of graphene foam/sodalite composite (SOD‐GF). Stable SOD and SOD‐GF film modified glassy carbon electrodes (GCE) without polymer were prepared and employed to study the electrochemical behaviour of chlorpromazine (CPZ) in different electrolyte pH
