Microbial Medicine Industry: Current Status and Future Trends

Yu Qing, Huang Tingting, Deng Zixin

Strategic Study of CAE 2021, Volume 23, Issue 5,   Pages 69-78 doi: 10.15302/J-SSCAE-2021.05.009

Abstract:

The microbial sourced natural products possess diverse structures and excellent activities, implying great potentials for clinical application. This study systematically analyzes the current status of the microbial medicine industry in China and summarizes the development trends of the industry from the aspects of microbial strain resource utilization, excellent strain screening, fermentation process optimization, strain engineering, and new microbial medicine development. This aims to facilitate major breakthroughs and industrial upgrades for China’s microbial medicine industry. Although China’s microbial medicine industry has solid resource and technical foundations, it still lags behind the international advanced level. Considering the opportunities and challenges, we propose several suggestions for promoting China’s microbial medicine industry: constructing large-scale scientific facilities for microbial medicine, strengthening basic research and independent technology development, establishing a talent cultivation system, and formulating systematic industrial incentives.

Mechanical behavior and semiempirical force model of aerospace aluminum alloy milling using nano biological

Frontiers of Mechanical Engineering 2023, Volume 18, Issue 1, doi: 10.1007/s11465-022-0720-4

Abstract: Aerospace aluminum alloy is the most used structural material for rockets, aircraft, spacecraft, and space stations. The deterioration of surface integrity of dry machining and the insufficient heat transfer capacity of minimal quantity lubrication have become the bottleneck of lubrication and heat dissipation of aerospace aluminum alloy. However, the excellent thermal conductivity and tribological properties of nanofluids are expected to fill this gap. The traditional milling force models are mainly based on empirical models and finite element simulations, which are insufficient to guide industrial manufacturing. In this study, the milling force of the integral end milling cutter is deduced by force analysis of the milling cutter element and numerical simulation. The instantaneous milling force model of the integral end milling cutter is established under the condition of dry and nanofluid minimal quantity lubrication (NMQL) based on the dual mechanism of the shear effect on the rake face of the milling cutter and the plow cutting effect on the flank surface. A single factor experiment is designed to introduce NMQL and the milling feed factor into the instantaneous milling force coefficient. The average absolute errors in the prediction of milling forces for the NMQL are 13.3%, 2.3%, and 7.6% in the x-, y-, and z-direction, respectively. Compared with the milling forces obtained by dry milling, those by NMQL decrease by 21.4%, 17.7%, and 18.5% in the x-, y-, and z-direction, respectively.
