Nanocellulose‐Based Aerogels for Adsorption Applications in Environmental Remediation: State of Art, Challenges, and Future Outlook

open access: yesRare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT The escalating severity of global environmental pollution necessitates the development of sustainable and efficient adsorption materials. Nanocellulose (NC), sourced from the most abundant natural polymer on earth, has shown great potential in this field due to its renewability, biodegradability, and exceptional nanoscale properties.

Resonance energy transfer from PbS colloidal quantum dots to bulk silicon: the road to hybrid photovoltaics

open access: yes, 2012
Semiconductor Quantum Dots (QDs) are promising materials for photovoltaic applications because they can be engineered to absorb light from visible to near infrared and single absorbed photons can generate multiple excitons.

Magnetron‐Sputtered Niobium‐Coated Biochar for Reusable Adsorption of Ivermectin and Diclofenac From Water

open access: yesChemistrySelect, Volume 11, Issue 36, 22 September 2026.
Magnetron sputtering was used as a controlled surface‐engineering strategy to produce a Nb‐coated biochar capable of adsorbing pharmaceuticals with markedly different molecular structures and adsorption behaviors. Maintaining removal performance across 11 adsorption–regeneration cycles and reducing it by no more than 15% in the presence of the tested ...

Navigating Classical and Nonclassical Realms of Nucleation and Crystallization

open access: yesSmall, Volume 22, Issue 50, 7 September 2026.
Classical nucleation and growth theories have long been foundational, yet recent nonclassical concepts have challenged and refined our understanding of solid‐state genesis. This paradigm shift introduced new, often ambiguous vocabulary. Here, we clarify key concepts, correct common misconceptions, and provide a terminological field guide across systems,

Metal‐Free Ternary‐Composite Aerogel Based on Graphitic Carbon Nitride, Graphene Oxide, and β‐Cyclodextrin for Synergistic Adsorption and Photodegradation of Organic Dyes

open access: yesSmall, Volume 22, Issue 49, 1 September 2026.
A novel metal‐free g‐C3N4/GO/β‐CD aerogel exhibits a high adsorption capacity of 653.2 mg/g for RhB. The synergistic adsorption‐degradation effect of the aerogel enables the complete elimination of organic dyes. Fixed‐bed and recyclability tests demonstrate its potential for continuous industrial wastewater treatment.

Interfacial Engineering of Dual‐Layer Au‐Shelled Ag Nanowires: Decoupling Chemical Stability From Ultrasensitive Surface‐Enhanced Raman Spectroscopy Activity

open access: yesSmall Science, Volume 6, Issue 9, September 2026.
A “Protection‐then‐Activation” strategy synthesizes 3D‐hierarchical AuNP‐Au@AgNWs, decoupling stability and surface‐enhanced Raman spectroscopy (SERS) activity. A hermetic inner Au shell protects the Ag core from corrosion, while overgrown porous Au nanoclusters generate dense volumetric hotspots. This robust 3D scaffold enables highly sensitive, label‐
