Solid-Gas Flow Characteristics of Drilling Bit-Rod Integral Structure by Hongtu Zhang, Ouya Zhang, Le Wei, Banghua Yao

“…The coal-gas two-phase flow path is an integrated structure composed of polycrystalline diamond compact (PDC) bit and drilling rod. In this work, CFD-DEM coupling numerical simulation was adopted to study the solid-gas flow characteristics of an integrated structure having PDC bit and gas velocity pipe under different gas velocity and solid mass flow rates. …”

Hydrothermal Catalytic Conversion of Glucose into Lactic Acid with Acidic MIL-101(Fe) by Xiaofang Liu, Zhigang Liu, Qiuyun Zhang, Hongguo Wu, Rui Wang

“…MIL-101(Fe) was explored for the first time for the catalytic conversion of glucose into lactic acid (LA). The as-synthesized MIL-101(Fe) was successfully characterized, and its higher specific surface area, porosity, and feasible acid properties were confirmed to determine the remarkable catalytic activity in glucose-to-LA conversion (up to 25.4% yield) compared with other catalysts like MIL-101(Cr, Al) and UiO-66(Zr). …”
