Current Chinese Science - Volume 2, Issue 1, 2022

Catalysis is a multidisciplinary field involving areas of organometallic chemistry, material science and engineering. It finds use in the synthesis of various industrially applicable compounds, such as fuels and fine chemicals. The activity and selectivity are fundamental issues to be dealt with in catalysis, which are associated with the high surface area. Current research activities primarily deal with homogeneous and heterogene Read More

Background: A larger response delay of a high-speed solenoid valve will cause inaccurate fuel injection timing and imprecise cycle injection quantity, resulting in diesel engine emission and increased fuel consumption. Objective: Biodiesel as an ideal alternative fuel has exceptional advantages in energy conservation, emission reduction, and low-carbon environmental protection; however, matching with Electronic U Read More

Background: The Environmental Management System (EMS) is a unique way to develop an environmental policy with adequate planning, including implementation, operation, checking, and management review. Objective: The main stages of the EMS encompass environmental policy, planning, implementation, evaluation, and review. Methods: A number of environmental standards (ISO 14000), which were drawn up by the inter Read More

Background: Amomum villosum is an important medicinal and edible plant owing to its valuable compositions of volatile and non-volatile compounds. Objective: The study was conducted to reveal the chemical constituents and medicinal values of A. villosum against various diseases. Methods: A critical and comprehensive data mining from 2004 to 2021 was performed based on CNKI, PubMed, and Google. Results: 12 Read More

Objective: To investigate the risk factors of kidney calculi in its high prevalence areas of western Guangdong, and provide the proper prevention measures. Methods: A cross-sectional survey was conducted among individuals in Maoming, western Guangdong. Univariate and Poisson regression analyses were applied to investigate the influence of the epidemiology, lifestyle, and environmental factors on renal calculi. Risk ratios w Read More

Background: Chronic Pancreatitis (CP) is a long-term risk factor for pancreatic ductal adenocarcinoma (PDAC), and both diseases share a common etiology. The activation of Pancreatic stellate cells (PaSCs) caused by inflammation of the chronic pancreas plays a pivotal role in the pathology of pancreatic fibrosis and the malignant phenotype of PDAC. However, the central role of activated PaSCs in Acinar-to-Ductal Metaplasia (A Read More
