Interferometry is a highly versatile tool for probing physical and chemical phenomena. In addition to the benefit of noncontact investigations, even spatially resolved information can be obtained by choosing a suitable setup. This review presents the evolution of the various setups that have evolved since the first interferometers were developed in the mid-nineteenth century and highlights the benefits, limitations, and typical areas of application. This review focuses on interferometry based on electromagnetic waves in the near-infrared and visible range applied to liquid samples, categorizes the chemical/physical properties (e.g., pressure, temperature, composition) and phenomena (e.g., evaporation, crystal growth, diffusion, thermophoresis) that can be assessed, and presents a comprehensive literature review of specific existing applications. Finally, it discusses some fundamental open questions with respect to geometric considerations and overlapping effects. Expected final online publication date for the Annual Review of Chemical and Biomolecular Engineering, Volume 13 is October 2022.

Microfluidic devices and systems have entered many areas of chemical engineering, and the rate of their adoption is only increasing. As we approach and adapt to the critical global challenges we face in the near future, it is important to consider the capabilities of flow chemistry and its applications in next-generation technologies for sustainability, energy production, and tailor-made specialty chemicals. We present the introduction of microfluidics into the fundamental unit operations of chemical engineering. We discuss the traits and advantages of microfluidic approaches to different reactive systems, both well-established and emerging, with a focus on the integration of modular microfluidic devices into high-efficiency experimental platforms for accelerated process optimization and intensified continuous manufacturing. Finally, we discuss the current state and new horizons in self-driven experimentation in flow chemistry for both intelligent exploration through the chemical universe and distributed manufacturing. Expected final online publication date for the Annual Review of Chemical and Biomolecular Engineering, Volume 13 is October 2022.

This article reviews recent developments in the applications of machine learning, data-driven modeling, transfer learning, and autonomous experimentation for the discovery, design, and optimization of soft and biological materials. The design and engineering of molecules and molecular systems have long been a preoccupation of chemical and biomolecular engineers using a variety of computational and experimental techniques. Increasingly, researchers have looked to emerging and established tools in artificial intelligence and machine learning to integrate with established approaches in chemical science to realize powerful, efficient, and in some cases autonomous platforms for molecular discovery, materials engineering, and process optimization. This review summarizes the basic principles underpinning these techniques and highlights recent successful example applications in autonomous materials discovery, transfer learning, and multi-fidelity active learning. Expected final online publication date for the Annual Review of Chemical and Biomolecular Engineering, Volume 13 is October 2022.

Designing functional materials requires a deep search through multidimensional spaces for system parameters that yield desirable material properties. For cases where conventional parameter sweeps or trial-and-error sampling are impractical, inverse methods that frame design as a constrained optimization problem present an attractive alternative. However, even efficient algorithms require time- and resource-intensive characterization of material properties many times during optimization, imposing a design bottleneck. Approaches that incorporate machine learning can help address this limitation and accelerate the discovery of materials with targeted properties. In this article, we review how to leverage machine learning to reduce dimensionality in order to effectively explore design space, accelerate property evaluation, and generate unconventional material structures with optimal properties. We also discuss promising future directions, including integration of machine learning into multiple stages of a design algorithm and interpretation of machine learning models to understand how design parameters relate to material properties. Expected final online publication date for the Annual Review of Chemical and Biomolecular Engineering, Volume 13 is October 2022.

'A second epoch of colonisation' this is how Wole Soyinka characterises Western theoretical practice as it applies itself, even with the best of intentions, to the cultural productions of the non-Western world. And it would be fair to say that post-colonial writing by which we mean writing that is grounded in the cultural realities of those societies whose subjectivity has been constituted at least in part by the subordinating power of European colonialism contains hundreds of such statements: statements which lay bare the material, often devastating, consequences of a centuries-long imposition of Euro-American conceptual patterns onto a world that is at once 'out there' and yet thoroughly assimilable to the psychic grasp of Western cognition.

“第二个殖民时代”，这是索因卡对西方理论实践的描述，因为它将自己应用于非西方世界的文化产品，即使是出于最好的意图。公平地说，后殖民写作我们指的是建立在这些社会的文化现实基础上的写作这些社会的主体性至少在一定程度上是由欧洲殖民主义的从属权力构成的它包含了数百个这样的陈述:这些陈述揭示了几个世纪以来欧美概念模式强加给一个世界的材料，往往是毁灭性的后果，这个世界既“在那里”，又完全可以被西方认知的精神把握所同化。这篇期刊文章可在Kunapipi找到:https://ro.uow.edu.au/kunapipi/vol11/iss1/3 STEPHEN SLEMON和HELEN TIFFIN

Nontherapeutic antimicrobial usage in animal farms has been associated with the development and spread of resistant bacteria. The emergence of serious life-threatening infections from veterinary and environmental sources and treatment failures occurring with the available antibiotics warrants investigation into resistance of antimicrobial agents in poultry farms. This study therefore provides information on antibiotic resistance pattern of bacteria isolated from five commercial poultry farms in Ile Ife, a peri-urban settlement in Nigeria. Isolation of bacteria from droppings, feed and water samples, was performed by spread plate method using all purpose and selective media. Morphological and biochemical characterization of isolates was done. The antibiotics sensitivity of the recovered isolates was determined by Kirby-Bauer disk diffusion method. A total 151 bacterial isolates, comprising 11 genera of 8 Gram negative and 3 Gram positive bacteria were recovered. E. coli had highest incidence rate of 21.19%, followed by Bacillus sp. with 15.23%; while the least recorded incidence of 1.32% was Citrobacter sp. All five farms recorded a 100% resistance to at least two (2) classes of antibiotics. A 100% resistance was recorded for augmentin in all five (5) farms, while 100% resistance in four (4) farms was recorded for cloxacilin. Furthermore a 100% resistance against erythromycin and cefixime respectively was documented in three farms. The least percentage resistance of 30% was against ciprofloxacin in only one farm, while the overall highest susceptibility of 39% was to ofloxacin. The multiple antibiotic resistance index (MARI) of isolates from all farms ranged from 0.3 to 1. Up to 9 bacterial genera had MARI 1, including E. coli, Salmonella, Bacillus, Klebsiella, and Pseudomonas. This study is a further indication that poultry farms represents an important reservoir of antibiotic resistance bacteria. It also serves as a pointer to the need for enforcement of regulatory antibiotics use in poultry farming by the government, and controlled usage by all stakeholders.

RNA is essential for cellular function: From sensing intra- and extracellular signals to controlling gene expression, RNA mediates a diverse and expansive list of molecular processes. A long-standing goal of synthetic biology has been to develop RNA engineering principles that can be used to harness and reprogram these RNA-mediated processes to engineer biological systems to solve pressing global challenges. Recent advances in the field of RNA engineering are bringing this to fruition, enabling the creation of RNA-based tools to combat some of the most urgent public health crises. Specifically, new diagnostics using engineered RNAs are able to detect both pathogens and chemicals while generating an easily detectable fluorescent signal as an indicator. New classes of vaccines and therapeutics are also using engineered RNAs to target a wide range of genetic and pathogenic diseases. Here, we discuss the recent breakthroughs in RNA engineering enabling these innovations and examine how advances in RNA design promise to accelerate the impact of engineered RNA systems.
