This perspective discusses the main issues with Zn anodes and highlights recent strategies to improve their performance in aqueous zinc ion batteries.

A brief introduction to chemical substitution-oriented design to discover high performance ultraviolet (UV) nonlinear optical (NLO) solid state materials is presented.

The grand challenge of materials science, discovery of novel materials with target properties, can be greatly accelerated by machine-learned inverse design strategies.

Copper-free click chemistry has resulted in a change of paradigm, showing that artificial chemical reactions can occur on cell surfaces, in cell cytosol, or within the body. It has emerged as a valuable tool in biomedical fields.

By employing an N-heterocyclic carbene (NHC) catalyst, we developed a versatile catalytic system that enables deaminative cross-coupling reactions of aldehydes with redox-active pyridinium salts.

Ratiometric polarity sensitive probe (RPS-1) contains two dyes of same absorption but different emissions utilized in comprehensive and quantitative detection of wide range of intracellular polarity.

Far-red/NIR emitting, two-photon absorbing, biostable aminosilapyronin dyes (ASiP^j) and their derivatives (NIR-ASiP^j) offer novel (ratiometric) bioimaging platforms.

Theranostic nanoprobes (SYL NPs) prepared from a newly designed NIR-II fluorophore and FDA approved DSPE-mPEG5000 were well tolerated and exhibited multifunctional potential in diagnosis (photoacoustic & fluorescence imaging) and phototherapy in animal models.

Deep neural networks have been increasingly used in various chemical fields. Here, we show that Bayesian inference enables more reliable prediction with quantitative uncertainty analysis.

A novel NIR-II theranostic nanoprobe, PSY (∼110 nm), was concisely developed, which demonstrated excellent photostability, high tumor uptake, superior S/N ratios and more efficient cancer treatment with minimal side effects than cisplatin.

Plasmonic black gold converts CO₂ to methane using solar energy.

Using WO₃ as a model material, we investigate how different oxygen vacancy concentrations affect trapping of photogenerated charges and photocatalytic reactions in metal oxides.

Rhodamine spirolactams with adjacent amino groups work as acid-resistant and photoswitchable fluorophores in single-molecule localization super-resolution imaging.

Understanding how mesoporous noble metal architectures affect electrocatalytic performance is very important for the rational design and preparation of high-performance electrocatalysts.

A diindenophenanthrene biradicaloid, formally derived from Chichibabin's hydrocarbon, is obtained in a short, scalable synthesis.

Postcoordination modification of Mg₂(dobpdc) with monoamines of various alkyl chain lengths enables facile fine-tuning of wettability and efficient oil–water separation.

Co-assemblies of platinum(II) complexes produce amplified circularly polarized phosphorescence emission.

A FRET-based method was developed for monitoring metal–amyloid-β complexation and identifying inhibitors against such interaction.

A new divergent synthetic pathway for skeletally distinct pyrimidine-containing medium-sized azacycles was developed. Diversity-generating reactions via selective bond cleavages or migrations from N-quaternized intermediates were designed, and 14 discrete core skeletons were synthesized in an efficient manner. The skeletal diversity of the resulting molecular frameworks was confirmed by chemoinformatic analysis.

Changes in lysosomal Cl⁻ concentrations induced by various substances are determined using a lysosomal chloride-selective fluorescent probe.

X-ray structures of nonheme {FeNO}⁶ and iron(III)-nitrito complexes bearing a tetraamido macrocyclic ligand are reported along with three different generation pathways.
