摘要： The last 10 years have witnessed the growth of artificial intelligence into different research areas, emerging as a vibrant discipline with the capacity to process large amounts of information and even intuitively interact with humans. In the chemical world, these innovations in both hardware and algorithms have allowed the development of revolutionary approaches in organic synthesis, drug discovery, and materials? design. Despite these advances, the use of AI to support analytical purposes has been mostly limited to data-intensive methodologies linked to image recognition, vibrational spectroscopy, and mass spectrometry but not to other technologies that, albeit simpler, offer promise of greatly enhanced analytics now that AI is becoming mature enough to take advantage of them. To address the imminent opportunity of analytical chemists to use AI, this tutorial review aims to serve as a first step for junior researchers considering integrating AI into their programs. Thus, basic concepts related to AI are first discussed followed by a critical assessment of representative reports integrating AI with various sensors, spectroscopies, and separation techniques. For those with the courage (and the time) needed to get started, the review also provides a general sequence of steps to begin integrating AI into their programs. ? 2021 Elsevier B.V.

摘要： 国家的改革与富强不仅促进了人民的经济水平增长,也促使现代社会的人们接触到更高品质的生活。食物是人生存依赖的基础,只有保障食品的安全性,人类才能生活得更加愉快舒心。所以,现代社会中的人们日渐注重健康和绿色饮食,对食品的质量问题均是零容忍。然而,由于利益的驱使,食品安全问题依旧并将长期是社会的热点问题之一,新闻报道中频繁出现食品生产加工行业的乱象。因此,人们对食品安全问题的重视和对健康食品的呼吁,使得食品安全检测成为大众关注的焦点。随着时代进步和科学技术的迭代更新,化学检测技术在食品安全检测中发挥了显著的作用。本文分析了食品安全现状及食品检测出现的问题,并探讨了食品安全检测中化学技术的应用。

关键词： Microfluidics  

摘要： Membranes play a crucial role in many microfluidic systems, enabling versatile applications in highly diverse research fields. However, the tight and robust integration of membranes into microfluidic systems requires complex fabrication processes. Most integration approaches, so far, rely on polydimethylsiloxane (PDMS) as base material for the microfluidic chips. Several limitations of PDMS have resulted in the transition of many microfluidic approaches to PDMS-free systems using alternative materials such as thermoplastics. To integrate membranes in those PDMS-free systems, novel alternative approaches are required. This review provides an introduction into microfluidic systems applying membrane technology for analytical systems and organ-on-chip as well as a comprehensive overview of methods for the integration of membranes into PDMS-free systems. The overview and examples will provide a valuable resource and starting point for any researcher that is aiming at implementing membranes in microfluidic systems without using PDMS.

摘要： Course-based undergraduate research experiences (CUREs) integrate authentic research into undergraduate chemistry laboratories, introducing students to research while simultaneously reinforcing fundamental concepts. Despite their ubiquitous nature in bioanalytical research, few CUREs have been published applying the fundamental techniques of separations, spectroscopy, quantification, and mass spectrometry. To engage students in learning these increasingly essential bioanalytical techniques, we designed and implemented a semester-long project-based course centered around the purification, quantification, and identification of heterologously expressed proteins in five succinct and adaptable modules. Instructors can use these modules to form the foundation of a CURE specific to their research interests. The extensive commercial availability of plasmids for transformation combined with the modular approach to laboratory experiments enables convenient customization to accommodate diverse research goals. Instructors can tailor the modules to meet the curricular requirements and instrumentation capabilities of their institutions and can easily extend the research goals to incorporate more specialized analytical techniques, as needed. Through the implementation of the five modules, students apply the fundaments of acid-base chemistry, statistics, quantification strategies, spectrophotometry, separations, and mass spectrometry, thus covering the material required in most undergraduate introductory analytical courses. Instructors can then use these modules as a backbone to support student-led discovery-based investigations for the remainder of the course. Students demonstrate their understanding through the completion of a comprehensive, publication-style laboratory report as well as a poster presentation at a university-wide undergraduate research symposium. Since first offering this course in 2016, student evaluations have been exceedingly positive, with over 75% of student
