Description

Chemistry was used a lot in the development of applications in glycosciences and in the decoration of synthetic multivalent scaffolds with glycans to mimic the glycocalyx on the cell surface. Oxime ligation, copper (I)-catalyzed alkyne–azide cycloaddition, thiol–ene coupling, squaramide coupling, and Lansbury aspartylation were found to be especially helpful in achieving this. This review provides a summary of synthetic strategies for conjugating multiple copies of the same or different glycans to cyclopeptide scaffolds (multivalent glycocyclopeptides) of varying size, valency, geometry, and molecular composition. In a one-pot manner, these strategies can be utilized stepwise or orthogonally. In 2022, polyrotaxanes' first scientific papers will be published. Over the past three decades, numerous combinations of polymer chains and molecular rings have been synthesized and studied. However, the types of polyrotaxanes that researchers were able to work with up until recently were restricted by synthetic methods, which typically rely on an inherent affinity between the polymer chains and molecular rings. Since the 2015 introduction of molecular pumps that form oligorotaxane, it is now possible to force multiple rings onto oligomer and polymer chains that have little or no affinity for the rings. These molecular pumps, which are able to actively recruit rings from solution to form precise polyrotaxanes, represent a significant advancement in the field. This Tutorial Review discusses significant turning points in the study and synthesis of polyrotaxanes as well as recent advancements in molecular pump synthesis and theory. Polyrotaxane properties have enabled them to outperform conventional polymers in a wide range of applications in materials, electronic, and biological science. These include slide-ring gels, robust coatings for mobile phones, molecular wires, flexible binders for battery anodes, and bio-cleavable polyplexes for cellular DNA delivery. Molecular pumps may revolutionize the synthesis of precise mechanically interlocked materials, particularly those involving non-equilibrium chemistry, energy storage, and nanomedicine. The study of liquid-repellent surfaces like superhydrophobic surfaces, superoleophobic surfaces, and slippery liquid-infused surfaces has piqued the interest of chemical synthesis, interfacial chemistry, surface engineering, bionic manufacturing, and micro-nano machining.

Extensive Intersection

This is due to the fact that they could be used in a variety of applications, including self-cleaning, chemical resistance, anti-icing, water/oil remediation, liquid proofing, and biomedicine. However, the applications of such surfaces in the real world are severely restricted due to their lack of robustness and durability, which remains their Achilles heel. Over the past few years, there have been numerous breakthroughs and a rapid increase in publications on the robustness and durability of liquid-repellent surfaces. This overview covers the most recent developments in the creation of strong and durable liquid-repellent surfaces. We'll talk about the wetting of solid surfaces and the typical characterisation methods for them before moving on to typical liquid-repellent surfaces. Second, we focus on a variety of evaluation methods for the robustness and durability of liquid-repellent surfaces. Thirdly, in-depth discussion is given to the most recent developments in the creation and design of strong, long-lasting liquid-repellent surfaces. Fourth, we discuss how these surfaces have been utilized in biology, chemistry, engineering, and everyday life. Last but not least, we discuss the various research paths into solid and long-lasting liquid-repellent surfaces that are open to investigation. By presenting such the current state of the art in this significant and rapidly developing field, we believe that this review will inspire multidisciplinary scientific communities and industrial circles to develop novel liquid-repellent surfaces that can meet the requirements of various real-world applications.

Limitations of Driving Carbon Dioxide (CO2)

If scenarios for reducing global warming are to be realized, carbon capture and storage (CCS) is absolutely necessary. However, the adaptability and scale of today's maturing thermochemical capture technologies are restricted by their rigid form factors and extremely high energy requirements. Using renewable electricity instead of heat to drive CO2 separations is a compelling alternative for overcoming these limitations. Even though electrochemical technologies have been extensively developed for processes like the storage of energy and utilization of CO2, the possibility of a more extensive intersection between electrochemistry and CCS has only recently received a growing amount of attention. There are a lot of scientific proofs-of-concept and a lot of ideas in the pipeline, all of which are at different stages of technology readiness. The emerging science and research that underpins electrochemical CCS processes is the subject of our evaluation in this paper, as is its current maturity and trajectory. In addition, we highlight novel ideas that merit continued investigation and development. Because of this, it will be possible to accurately evaluate the effect that electrochemical CCS will have in the years to come. In Molecular Solar Thermal Energy Storage Systems (MOST), emission-free energy is stored in molecular photoswitches by valence isomerization of solar energy. These photoswitchable molecules can later release the stored energy as heat upon demand. Systems of this kind are now a thriving field of study that is quickly moving from fundamental research to applications. Because molecular design and engineering receive the majority of attention, MOST-based device development has not been systematically summarized and presented to a broad audience. In this tutorial review, the most widely used and developed devices will be discussed from a chemical engineering perspective. It is anticipated that future MOST technology developers will be inspired by existing devices in light of the summarized essential practical challenges to large-scale implementations and more innovative applications. Ultrathin two-dimensional (2D) materials offer a wide range of potential applications due to the quantum confinement effect and increased specific surface area to volume ratio. Due to their atomic thickness and various orientations, ultrathin 2D materials that expose specific facets have received a lot of attention for a variety of applications in catalysis, batteries, optoelectronics, magnetism, and as an epitaxial template for material growth, among other fields. Advances are being made, despite the difficulty of controlling crystal facets while simultaneously maintaining the atomic thickness of 2D materials. This review provides a comprehensive overview of recent developments in facet engineering of 2D materials, beginning with a fundamental understanding of facets and the corresponding approaches to the significance of facet engineering. Some of our predictions and suggestions for the future include creating a facet database, developing novel two-dimensional materials, designing specific substrates, and introducing theoretical calculations and characterization techniques. This review's insights into how to design ultrathin 2D materials with distinctive features can be used in energy, magnetism, optics, biomedicine, and other fields.
