AbstractThe development of sodium-ion (SIBs) and potassium-ion batteries (PIBs) has increased rapidly because of the abundant resources and cost-effectiveness of Na and K. Antimony (Sb) plays an important role in SIBs and PIBs because of its high theoretical capacity, proper working voltage, and low cost. However, Sb-based anodes have the drawbacks of large volume changes and weak charge transfer during the charge and discharge processes, thus leading to poor cycling and rapid capacity decay. To address such drawbacks, many strategies and a variety of Sb-based materials have been developed in recent years. This review systematically introduces the recent research progress of a variety of Sb-based anodes for SIBs and PIBs from the perspective of composition selection, preparation technologies, structural characteristics, and energy storage behaviors. Moreover, corresponding examples are presented to illustrate the advantages or disadvantages of these anodes. Finally, we summarize the challenges of the development of Sb-based materials for Na/K-ion batteries and propose potential research directions for their further development.

Mass And Heat Transfer

: In recent years, the development of the chemical industry has been moving in a green, safe and efficient direction. Oxidation reactions are one of the most important types of reaction, and have key applications in food, medicine, and cosmetics, petrochemicals. However, the occurrence of the oxidation reaction is accompanied by a strong exothermic phenomenon, and improper control can easily lead to safety problems and even explosions. The realization of an environmentally friendly oxidation reaction is a key industrial milestone. The unique structural characteristics of microreactors result in good mass and heat transfer performance, precise control of the reaction temperature, reduced risk of explosion, improved safety production and selectivity of products. These unique advantages of the microreactor determine its significant application value in oxidation reactions. In this paper, the research progress of several typical oxidation reactions including alkane oxidation, alcohol oxidation, aldosterone oxidation, aromatics oxidation and olefin oxidation combined with microreactors is reviewed systematically.

Stress Related Genes

Basic helix-loop-helix proteins (bHLHs) comprise one of the largest families of transcription factors in plants. They have been shown to be involved in responses to various abiotic stresses, such as drought, salinity, chilling, heavy metal toxicity, iron deficiency, and osmotic damages. By specifically binding to cis-elements in the promoter region of stress related genes, bHLHs can regulate their transcriptional expression, thereby regulating the plant’s adaptive responses. This review focuses on the structural characteristics of bHLHs, the regulatory mechanism of how bHLHs are involved transcriptional activation, and the mechanism of how bHLHs regulate the transcription of target genes under various stresses. Finally, as increasing research demonstrates that flavonoids are usually induced under fluctuating environments, the latest research progress and future research prospects are described on the mechanisms of how flavonoid biosynthesis is regulated by bHLHs in the regulation of the plant’s responses to abiotic stresses.

AbstractCharacterization of structural heterogeneity of liquid solutions and the pursuit of its nature have been challenging tasks to solution chemists. In the last decade, an emerging method called excess spectroscopy has found applications in this area. The method, combining the merits of molecular spectroscopy and excess thermodynamic functions, shows the ability to enhance the apparent resolution of spectra, provides abundant information concerning solution structures and intermolecular interactions. In this review, the thinking and mathematics of the method, as well as its developments, are presented first. Then, research progress related to the exploration of the method is thoroughly reviewed. The materials are classified into two parts, small-molecular solutions and ionic liquid solutions. Finally, potential challenges and the perspective for further development of the method are discussed.

Biological systems have their unique color generation mechanisms based on the selective reflection of light using colorants, scattering, interference and diffraction principles. Plants and animals can use either biochromes or schemochromes effectively thus presenting to us a beautiful colored world. Biochromes like chlorophylls and carotenoids are colorants synthesized by biological systems via a biochemical process and can reflect components of white light selectively, whereas schemochromes rely on the colorless structural characteristics of a biological component to generate a specific range of the visible light. Examples of both biochromes and schemochromes are presented and the current research progress discussed in this review.

The rapid research progress in tin-based binary sulfides (SnxSy = o-SnS, c-SnS, SnS2, and Sn2S3) by the solution process has opened a new path not only for photovoltaics to generate clean energy at ultra-low costs but also for photocatalytic and thermoelectric applications. Fascinated by their prosperous developments, a fundamental understanding of the SnxSy thin film growth with respect to the deposition parameters is necessary to enhance the film quality and device performance. Therefore, the present review article initially delivers all-inclusive information such as structural characteristics, optical characteristics, and electrical characteristics of SnxSy. Next, an overview of the chemical bath deposition of SnxSy thin films and the influence of each deposition parameter on the growth and physical properties of SnxSy are interestingly outlined.

Polypeptoids have attracted a lot of atteSDntion because of their unique structural characteristics and special properties. Polypeptoids have the same main chain structures to polypeptides, making them have low cytotoxicity and excellent biocompatibility. Polypeptoids can also respond to external environmental changes by modifying the configurations of the side chains. The external stimuli can be heat, pH, ions, ultraviolet/visible light and active oxygen or their combinations. This review paper discussed the recent research progress in the field of stimulus-responsive polypeptoids, including the design of new stimulus-responsive polypeptoid structures, controlled actuation factors in response to external stimuli and the application of responsive polypeptoid biomaterials in various biomedical and biological nanotechnology, such as drug delivery, tissue engineering and biosensing.

In recent years, natural polysaccharides have received growing attention and interest in view of their values in food, medical, cosmetics and other fields. Eleutherococcus senticosus (E. senticosus) is a medicine and food homologous plant that possess anti-tumor, anti-inflammatory, central nervous system and cardiovascular protection, anti-radiation, enhancement of human microcirculation, improvement of physical fatigue effects, mainly based on lignans, flavonoids and coumarin types. E. senticosus polysaccharides (ESPS), act as a kind of polysaccharide extracted and isolated from the root and rhizome of E. senticosus, have been found in many applications of medicine and food for their unique biological activity. Nevertheless, the existing studies are mostly concerned with small molecules of E. senticosus, less attention is paid to polysaccharides. Moreover, the types and structural characterization of ESPS reported in existing literature were also not summarized. In this paper, the research progress of ESPS is reviewed from the aspects of extraction, separation, structural characterization and biological activity, future perspectives from points of efficient extraction, resource utilization and quality control standards were also proposed, which provide reference for the further development and utilization of ESPS.

Pt-based alloys are being developed for high-temperature applications with the aim of replacing some of the currently used Ni-based superalloys (NBSAs) and benchmark alloy, PM2000. The Pt-based superalloys have a similar structure to the NBSAs and can potentially be used at higher temperatures and in more aggressive environments because Pt is more chemically inert and has a higher melting point. In this paper, the recent progress in research and development of Pt-based superalloys is overviewed. Firstly, the composition optimization and structural design of Pt-base superalloys are introduced. The structural characteristics, mechanical properties, oxidation resistance and corrosion behavior of Pt-Al ternary, quaternary and multiple superalloys are summarized. Finally, directions for further research and application of Pt-base superalloys are analyzed and prospected.
