Shape-controlled metal nanocrystals have attracted growing interest due to their enhanced catalytic performance, cost-efficiency, and well-defined features for mechanistic investigations. However, the ultimate potential of these nanocrystals is limited by their surface heterogeneity. This review delves into the intricacies of surface heterogeneity, examining its role in dictating the sites for atom deposition and thereby the growth pattern of metal nanocrystals during colloidal synthesis. We also highlight the critical role of surface diffusion in preserving or overriding the impacts of surface heterogeneity, alongside the dynamic nature of surface structure throughout nanocrystal growth. Understanding and controlling the surface heterogeneity of nanocrystals are essential to the development of advanced catalytic materials.

Covalent organic frameworks (COFs) are a useful class of crystalline porous materials assembled from organic molecular precursors via covalent bonds. Single-crystalline COFs have gained increasing attention because of their unique advantages, such as well-defined structures and improved performance, compared with their polycrystalline counterparts. However, the development of such materials has been severely hampered due to the lack of general synthetic strategies and effective characterization methods. This review surveys recent advances in the preparation of single-crystalline COFs, provides a perspective on the current challenges, and proposes future directions for the exploration of this promising class of crystalline polymers.

Over the past decade, hybrid perovskite research has evolved to a point where the literature contains an enormous volume of chemical and physical information. However, many essential material design challenges remain open for researchers to address. The dispersed nature of the large, rapidly growing body of hybrid perovskite materials data poses a barrier to systematic discovery efforts, which can be solved by materials property databases, either by high-throughput or by systematic, accurate human-curated efforts. This opinioned review article discusses the necessity, challenges, and requirements of building such data libraries. In light of using machine learning (ML) and related tools to solve specific problems, the importance of information related to different material attributes and properties is also highlighted.

Propane dehydrogenation to propylene has received increasing attention due to the fast growth in propylene demand and the exploration of shale gas containing propane. Direct dehydrogenation of propane (DDHP) offers high propylene selectivity but is limited by quick deactivation due to coke formation. CO2-assisted oxidative dehydrogenation of propane (CO2-ODHP) can consume CO2 and meanwhile reduce coke deposition via the reverse Boudouard reaction. In the current review, direct and CO2-assisted dehydrogenation of propane has been compared from three aspects: reaction mechanisms, catalyst compositions, and CO2 footprint analysis. As the average CO2 emissions from electricity generation decrease due to the utilization of renewable energy, CO2-ODHP potentially leads to a net-negative CO2 footprint while DDHP cannot.

Progress toward achieving global food security continues to be hindered by several economic, geo-political, and environmental variables which has led the United Nations to place emphasis on achieving Zero Hunger by 2030. Thus, it is important to invest in novel, eco-friendly, and cost-effective solutions that will increase agricultural productivity. For this reason, nanoscale materials are increasingly being developed for use in agriculture with attention on controlling various properties such as size, shape, surface modifications, and transformations for improved impact in plants. With continued interdisciplinary and collaborative efforts among nanoparticle experts and plant scientists, the research area will evolve to identify the best nanoparticle properties for foliar application to plants.

Lignin, the only large-volume sustainable source of aromatic biopolymer in nature, is an attractive feedstock for the production of functional materials. However, considering its high reactivity, lignin is difficult to extract without avoiding uncontrolled degradation and condensation, which significantly impedes the upgrading of the extracted lignin into high-valued materials. Deep eutectic solvents (DES), as an emerging solvent choice, have driven innumerable advances in sustainable biorefinery, especially in lignin fractionation and valorization. Due to their property tunability and high lignin solubility, lignin modification with DES is an appealing approach to boost the extracted lignin’s reactivity and compatibility with polymers. This review systematically summarizes the latest progress of DES in lignin modification and further upgrading into functional materials.
