Monodisperse Condensed Tannin and Derived Carbon Nanospheres Featuring Well‐Defined Surface‐Structured Metal Species

open access: yesSmall, EarlyView.
Uniform, size‐tunable polyphenol nanospheres are assembled from condensed tannins in water at ambient conditions via controlled supramolecular interactions between tannin and diamines. Their phenolic–amine surfaces template highly dispersed metal species that resist sintering during pyrolysis.

Sprayable MXene Hydrogels With Composition‐Driven Interfacial Stabilization and on‐Skin Gelation for Conformal Postsurgical Photothermal Therapy

open access: yesSmall, EarlyView.
A sprayable MXene‐loaded thermosensitive hydrogel was developed for postoperative melanoma treatment. Molecular simulations combined with experimental analyses demonstrated that polymer composition regulates MXene oxidation. The optimized hydrogel effectively preserved photothermal performance under physiological conditions, enabling efficient near ...

Molecularly Regulated Dynamic Interfaces in 3D/2D Perovskites Enabled by Functional Pyridinium Ionic Liquids

open access: yesSmall, EarlyView.
1‐butyl‐4‐methylpyridinium tetrafluoroborate (BMPyBF4) interacts with excess PbI2 during film formation, driving the formation of a low‐dimensional perovskite phase and enabling the self‐organization of a 3D/2D interfacial structure. This molecularly regulated interface suppresses defect‐mediated recombination and facilitates interfacial charge ...

Insights Into the Mechanistic Assessment of Plasmon‐Induced Aqueous Degradation of Pharmaceuticals by TiO2/Ag Nano‐Composite

open access: yesWater and Environment Journal, EarlyView.
ABSTRACT Pharmaceutical contaminants in potable water sources are ubiquitous and have resulted in lowered water quality. Thus, two common broad‐spectrum pharmaceuticals (tetracycline‐TC and ciprofloxacin‐CPF) were comparatively photo‐degraded using Ag‐doped TiO2 photocatalyst species containing Ag nanoparticles at 2.5, 5, and 7.5 wt%.

From Flybys to Sample Return: A Review of Space Probes and Robotic Sampling Technologies for Small Bodies

open access: yesJournal of Field Robotics, Volume 43, Issue 7, Page 4475-4514, October 2026.
ABSTRACT As a crucial puzzle piece of deep space exploration, exploring small bodies can provide significant scientific insights and valuable mineral resources. Unlike missions to the Moon and Mars, small‐body missions pose distinct technical challenges, including communication delays, weak gravity, and uncertain environments. This paper reviews a full

CO2 Activation by Small Copper, Cobalt, and Yttrium Oxide Clusters Probed via Infrared Multiple‐Photon Dissociation Spectroscopy

open access: yesChemPhysChem, Volume 27, Issue 17, 14 September 2026.
Infrared multiple photon dissociation spectroscopy is used to study the activation of CO2 on Cu‐, Co‐, and Y‐oxide clusters. While CO2 activation is not possible on cationic clusters, the binding motif on anionic clusters depends on a fine interplay between the nature and energetic location of the molecular orbitals and the charge (oxidation state) on ...

Far‐Infrared Hyperbolic Phonon–Polaritons in Zirconium Disulfide

open access: yesAdvanced Materials, Volume 38, Issue 52, 16 September 2026.
An unpatterned ZrS2${\rm ZrS}_2$ flake, coupled to far‐field infrared light by metal nanoribbons, reveals hyperbolic phonon polaritons with multiple higher‐order branches and effective refractive indices up to 223. This resonator‐assisted approach establishes ZrS2${\rm ZrS}_2$ as a compact van der Waals platform for deeply subwavelength far‐infrared ...
