摘要:
In 1998, Paul Anastas and John Warner defined 12 Principles of Green Chemistry, aiming at cleaner processes, safer products and increasing use of renewable rather than fossil resources. With the growing awareness of environmental issues, the international chemical community is driven to develop novel and environmentally friendly synthetic strategies for the replacement of inefficient and pollutional chemical processes. Delightedly, a lot of ecofriendly synthetic methodologies have been established over the past decades.

摘要:
An environmentally friendly method for the synthesis of 3-organylselenyl quinolones through the electrochemical cross-dehydrogenative coupling of 4-quinolones and diorganyl diselenides was developed. As a green, atom economic and self-separating process, the present reaction requires neither external oxidants nor electrolytes, forming a recyclable catalytic system.

摘要:
Clean production, as an important part of green chemistry, has received great attention and considerable development in recent years. In this perspective article, we summarized some examples of (nearly) quantitative synthesis, clean separation and purification to emphasize clean production. These reactions were carried out by using eco-friendly solvents and the pure products could be easily obtained through clean procedures.

摘要:
通过向阳极催化层中添加高分子化合物亲水剂,制备了一种具有自增湿能力的膜电极。考察了亲水性高分子化合物的种类、相对湿度(RH)以及电池温度对膜电极自增湿性能的影响,并初步探索了膜电极的自增湿机理。结果表明,以羧甲基纤维素(CMC)为保水剂的膜电极表现出最好的低湿度性能;膜电极的自增湿性能受相对湿度影响不大,但随着温度的升高,其性能先升高后降低;在电池温度为60℃、20%RH、206 k Pa条件下,以羧甲基纤维素为保水剂的膜电极在0. 6 V的电流密度为900 m A/cm2,是空白膜电极的1. 8倍。
摘要:
OBJECTIVE: Type 1 diabetes (T1D) results from dysfunction of pancreatic islets beta cells. Recent studies supported that endoplasmic reticulum (ER) stress takes an important role in pancreatic beta cell excessive loss, resulting in T1D. Here, we aimed to review the relationship between ER stress and T1D. Additionally, we also reviewed the potential mechanisms underlying ER stress mediated T1D. DATA SOURCES: This review was based on the articles from PubMed databases up to July 2019, with the following keywords: "endoplasmic reticulum stress", "inflammation", "autoimmunity", and "type 1 diabetes". STUDY SELECTION: Original articles and critical reviews on the topics were selected and carefully analyzed. RESULTS: Studies have shown that severe ER stress is directly involved in the pancreatic beta cells destruction and pathogenesis of T1D. CONCLUSIONS: ER stress plays a key part in pancreatic beta cells and T1D, which will help in developing new effective therapeutics for T1D.

摘要:
Although metal-organic frameworks (MOFs) show numerous advantages over other crystalline materials, their industrial relevances have been impeded owing to their many drawbacks such as environmental impacts and economic costs of their synthesis. A green preparation pathway could greatly reduce the environmental costs, energy, and the need for toxic organic solvents, and consequently reduce the production cost. Thus, the most desirable synthesis route is the replacement of harsh organic solvents with aqueous solutions to abate environmental and economic impacts. This review summarizes recent research advancements of water-based routes for MOF synthesis and gives a brief outline of the most prominent examples. The challenges and prospects of the commercialization of promising MOFs in the future are also presented. This study aims to offer necessary information regarding the green, sustainable, and industrially acceptable fabrication of MOFs for their commercial applications in the future.

摘要:
Sulfur-containing organic compounds such as sulfides,sulfoxides and sulfones, have played significant roles in the fields of organic synthesis, pharmaceuticals, and agrochemicals.The selective oxidation of the parent sulfides has been considered as one of the most straightforward methods for the construction of sulfoxides and sulfones.Therefore, a plethora of oxidative systems have been developed for the selective oxidation of sulfides, in which strong oxidants like organic/inorganic peroxides, hypervalent iodines, highpressure oxygen, were required with/without the catalysis of transition metals.In the point view of green chemistry, the application of atmospheric molecular oxygen as an oxidant for the selective oxidation of sulfides under mild conditions is highly desired.
