Amphiphilic cyanostilbene 12CS12 underwent self-assembly in aqueous media and exhibited bright greenish-yellow emission in its aggregated state. Macrocyclic host cucurbit[7]uril (CB[7]) was found to encapsulate 12CS12 and the host-guest complex was an efficient bluish-cyan emitter. Variation of the 12CS12 and CB[7] ratio in their mixture generated multiple emission colors including near white light through the color mixing of these two emitting species.

The solvation structure of an Np ion in an aqueous, noncomplexing and nonoxidizing environment of trifluoromethanesulfonic (triflic) acid was investigated with X-ray absorption spectroscopy (XAS) combined with ab initio molecular dynamics (AIMD) and time-dependent density functional theory (TDDFT) calculations. Np L-edge X-ray absorption near-edge structure (XANES) and extended X-ray absorption fine structure (EXAFS) data were collected for Np in 1, 3, and 7 M triflic acid using a laboratory-scale spectrometer and separately at a synchrotron facility, producing data sets in excellent agreement. TDDFT calculations revealed a weak pre-edge feature not previously reported for Np L-edge XANES.

Precision in controlling the microenvironment of nanospaces is a potent strategy for exploring architecture‒function relationships. Herein, a face-capped tetrahedral cage, featuring Pd‒Pd-bonded vertices, with a tailored nanospace surrounded by 12 ethyl units, was facilitated to adaptively accommodate a library of guests with different sizes and shapes, including C6 cyclic hydrocarbons, adamantane derivatives, S and P. This nanocavity can achieve strong binding with cyclohexane in non-aqueous media in contrast to reported structurally similar non--functionalized cages by an increase of four orders of magnitude.

Particles with some degree of hydrophilicity are known to aggregate when directly dispersed in non-aqueous media. Proteins are generally insoluble in oil and have complex surface properties, but they may form networks in oil like more simple colloidal particles, depending on particle size and surface hydrophilicity. Here, the particle size of pea protein isolate (PPI) particles in oil was reduced to submicron sizes by stirred media milling.

To expand the application scope of carbon steel, imparting superhydrophobicity to its surface offers an effective strategy to overcome its inherently poor corrosion resistance. However, in marine environments, conventional superhydrophobic coatings often suffer from limited mechanical durability and inadequate long-term corrosion protection. In this study, a durable superhydrophobic bilayer coating composed of PDMS-MWCNTs (top layer) and PDMS (bottom layer) was developed to address these challenges.

Conventional optical probes suffer from signal degradation in aqueous media, hindering sensitive biodetection. To overcome this, newly developed water-insensitive down-shifting nanoparticles (WINPs) possess superior photophysical properties in the NIR-I window, including high quantum yield and negligible thermal effects, permitting stable, high-contrast signal generation under low excitation power. This advantage facilitated a low-power lateral flow assay capable of highly sensitive avian influenza virus (AIV) detection in the opaque biological matrices (such as avian swabs), mitigating interference issues relying on visible-range signals.
