  • In this review, we highlight the recent progress in two rising areas: solar energy conversion through plasmon-assisted interfacial electron transfer and plasmonic nanofabrication. Localized surface plasmon resonance (LSPR) of plasmonic nanoparticles and nanostructures has attracted increasing attention because of their strong near-field enhancement by interacting with visible light. Recent studies have demonstrated the capability of such plasmonic systems in producing ‘LSPR-induced hot-electrons’ that are useful in photoenergy conversion and storage when combined with electron-accepting semiconductors. Concurrently, ‘hot-electron decay’ results in strong photothermal responses or plasmonic local heating. This heating has received renewed interest in photothermal manipulation of nanoparticles and molecules.

  • Fluorine, the element with the highest electronegativity and low electric polarizability, can produce a variety of characteristics, including specific adsorption sites for molecules as well as flexibility to the host materials. In this review, we will introduce fluorine-functionalized metal–organic frameworks/porous coordination polymers that show unique and unprecedented structures, structural transformations, and gas and vapor adsorption/separation properties derived from the fluorine characteristics.

  • Graphene nanomaterials hold great promise for the development of advanced water purification membranes, especially for water desalination. Their atomic thickness, extraordinary mechanical stability and potential for size-selective transport are ideal features, encouraging the membrane scientist across the world to investigate their applicability for water desalination. Graphene can potentially desalinate water either as monolayer or as multilayer membranes. In this review, we discuss these different classes of graphene membranes and highlight their merits and shortcomings. In addition, the theory behind their performance is presented in detail.

  • Formed by the self-assembly of protein subunits, protein nanocages can be engineered at the interior, exterior, and inter-subunit locations. Each type of modification can be tuned for specific biological applications. Multiple-modifications can be imparted to these nanocages without compromising its self-assembling property, creating multi-functional protein nanocage platforms. Potential applications of the modified protein nanocages include targeted delivery in complex cellular environments for therapeutic and diagnostic agents as well as modulation of cellular responses.

  • This review summarizes recent results on the syntheses and characterization of the non-native phases of h-CoO, h-MnO and c-ZnO transition metal monoxides compared to their native phases. The investigation of the size- and phase-selective synthetic methods, formation mechanism and unique physicochemical properties of non-native transition metal monoxides would have an enormous impact on materials chemistry and open a promising avenue for magnetic, electronic, and spintronic applications.

  • The microstructure dynamics of electrode materials during battery cycling is dictated by the coupling between their lattice, charge and orbital characteristics, as shown in the schematic. TEM monitoring enables tracking lattice and chemical bonding at high spatial resolution, and thereby establishes the relationship between structure and performances.

  • PHAs are natural biodegradable polyesters synthesized by microorganisms. However, several disadvantages such as their poor mechanical properties and limited functionalities limit their competition with traditional synthetic plastics or their application as ideal biomaterials. To circumvent these drawbacks, PHAs need to be modified to ensure improved performance in specific applications. Well-established modification methods of PHAs are summarized and discussed. The improved properties of PHA that blends with natural raw materials or other biodegradable polymers are summarized. The functionalization of PHAs by block copolymerization and graft copolymerization is described. The expanded utilization of the modified PHAs as (bio)engineering materials is addressed.

  • This review highlights the recent advances in utilizing a combinatorial strategy of mechanistic investigation, theoretical prediction and experimental validation to develop cheap and earth-abundant high-performance electrocatalysts as counter electrode materials for dye-sensitized solar cells. The effectiveness of the combinatorial strategy over the conventional ‘trial-and-error’ tactic is illustrated with plentiful successful examples of earth-abundant materials. Perspectives are given to elucidate the opportunities and challenges.
