It is very urgent to solve environmental pollution problem. MXene-based composite photocatalysts show great promise, which utilize solar energy for purification. MXenes have excellent electrical conductivity, a large surface area due to their 2D structure, and surface functional groups beneficial for photocatalysis. In this review, various synthesis methods have been developed to prepare MXenes with different properties for specific applications, such as hydrofluoric acid etching, substitutes etching and molten fluoride etching. The influence of different groups on the performance of MXene have been determined. In photocatalytic reactions, modification strategies including heterojunction construction, doping, precious metal deposition and single atom anchor have been explored to enhance the photocatalytic performance of MXene-based composites. It is found that MXenes can act as support that limits photocatalyst size, enhance reactant adsorption, and functions as cocatalyst loaded onto semiconductors to improve charge separation. Our perspectives on the key challenges and future directions of developing high-performance MXene-based composite photocatalysts for environmental application are elaborated.

The interest of medicinal chemists in strained spiro heterocycles has continuously risen, given their potential as non-classical three-dimensional bioisosteres, as it has been shown that their inherent structural characteristics can impose beneficial physicochemical properties on lead compounds (e.g., metabolic stability, lipophilicity). In particular, strained spiro heterocycles containing at least one four-membered ring are in demand, as the inclusion of a small ring results in a more rigid and denser molecular space, whereas the inclusion of a heteroatom allows for placement of an exit vector orthogonal to the neighbouring carbon-centered exit vectors. The continuous development of new strained spiro heterocycles, their site-specific functionalisation, and their application as bioisostere is thus imperative. This review provides an overview of progress since 2014 with a particular focus on heteroatom-containing spiro[2.3]hexanes and spiro[3.3]heptanes.

The impact of linkage orientation as minor structural changes on the overall properties of covalent organic cages (COCs) has been investigated for the first time. Isomeric imine-linked donor–acceptor COCs, featuring triphenylamine as the donor and anthracene as the acceptor, TNCA and TCNA, were synthesized and exhibited significant differences in their optoelectronic properties, which in turn affect their photocatalytic performance.

A lithium-rich lithium-lead alloy-based composite electrode, featuring Li22Pb5 microparticles dispersed in lithium metal, is fabricated by mechanical rolling to suppress lithium dendrite growth. The lithiophilic Li-Pb alloys can guide a uniform lithium plating process, resulting in impressive cycling stability of both symmetric and full cells.

Reducing the particle size of the metal-organic frameworks (MOFs) MIL-68(In) and ZIF-8 leads to increased adsorption of volatile semiochemical guests. Opposing trends were observed in release dynamics, with the release rate of isobutyl acetate increasing with particle size for MIL-68(In) and decreasing for ZIF-8, which can be attributed to the lower diffusion barriers through channels in comparion to moving between discrete pores.

Theoretical calculations have shown great potential as an instructional, reliable, and robust tool for designing and optimizing electrolyte formulations for lithium-ion batteries. However, there is still a lack of clear understanding of the design principles and synergistic effects between each component of electrolytes, including lithium salts, solvents, additives, etc., especially on how to optimize each part of electrolytes from atomic scale and molecular scale. In this review, we cover the quantum chemistry in lithium salt selection, functional additive design, solid electrolyte interphase film study, and reaction mechanism speculation; molecular dynamics simulation in solvation structure, interphase simulation, and dendrite growth study; and high throughput simulation in functional electrolyte screening. Meanwhile, the limitations of each type of simulation are discussed. Finally, the conclusions and outlook regarding theoretical calculations for electrolyte design of lithium-ion batteries are presented.

We report for the first time the amplified spontaneous emission (ASE) and lasing from blue-emitting silicon nanoclusters. The lasing threshold is determined as 1.8 mJ per pulse and the emission peaks at 434 nm. The laser-induced emission experiments demonstrated in this study encourage further development of solution-processed fabrication of a colloidal silicon quantum dot laser.

Water-soluble nanoparticles (NPs) based on the well-defined 4ThIID molecules, namely 4ThIID NPs, were prepared. Benefiting from the strong NIR-II absorption and high photothermal conversion properties of 4ThIID, the ε1064 × PTCE1064 value of 4ThIID NPs reaches 9.18 × 104, which is the highest value among the reported NIR-II photothermal small molecules. In vivo experiments show that 4ThIID NPs can effectively inhibit the growth of tumors in mouse models under the irradiation of a 1064 nm laser.
