Linearized Three‐Dimensional Planing in Deep and Shallow Water

International Journal for Numerical Methods in Engineering, Volume 126, Issue 23, 15 December 2025.
ABSTRACT The traditional analysis of three‐dimensional planing is studied in detail using potential‐flow theory together with linearized free‐surface conditions. The work is extended here to the case of water of finite depth. The planing surface is modeled as a traveling pressure distribution.

Molar‐Scale Phenolic Acid Decarboxylation Using Thermostable Biocatalysts and Enzyme‐Compatible Deep Eutectic Solvents

ChemSusChem, Volume 18, Issue 24, December 13, 2025.
Thermostable phenolic acid decarboxylases (PADs) catalyze the synthesis of hydroxy styrenes in deep eutectic solvents (DESs) tuned for solubility and enzyme stability. Betaine–glycerol (1:2) is halide‐free, stabilizing PADs at 50–70 °C, and increases ferulic acid solubility 14× over buffer.

Upconversion Nanoparticle‐Covalent Organic Framework Core–shell Particles as Therapeutic Microrobots Trackable With Optoacoustic Imaging

Advanced Materials, Volume 37, Issue 49, December 10, 2025.
Upconversion nanoparticle‐covalent organic framework core–shell particles provide enhanced contrast for optoacoustic imaging by leveraging the optical absorption of upconversion luminescence within the covalent organic framework matrix. Beyond their role as contrast agents, these particles enable customizable therapeutic agent loading and release, as ...

Preparation of Model Surfaces to Mimic Porous Cellulose Structures

Advanced Materials Interfaces, Volume 12, Issue 24, December 22, 2025.
This study presents 2D ultrathin nanocellulose model surfaces that mimic porous cellulose materials. The surfaces are prepared via a sacrificial templating approach, by spin coating nanocellulose and polystyrene nanoparticles suspension on a substrate, followed by nanoparticle removal.

The Role of Porosity in SERS

Advanced Optical Materials, Volume 13, Issue 34, December 2, 2025.
This review explores how engineered porous materials enhance surface‐enhanced Raman scatering (SERS) spectroscopy by synergizing analyte enrichment and electromagnetic field amplification. It is systematically evaluated four classes, nanoporous metals, plasmonic polymers, mesoporous silica, and metal‐organic frameworks (MOFs), highlighting their unique

Graded Plasmonic Metagratings for Directional Nonlinear Optical Sensing

Advanced Optical Materials, Volume 13, Issue 35, December 12, 2025.
A refractometric sensing approach is presented, based on the angular variation of the emission pattern while changing the local environment. This method is first demonstrated on rectangular arrays, then on an aperiodic metagrating configuration designed to shape the first diffraction orders into a broadened band. Abstract Plasmon‐enhanced sensing based

Corn Zein Nanocarriers for Agrochemical Delivery and Smart Packaging

Advanced Sustainable Systems, Volume 9, Issue 12, December 2025.
This review explores zein, a corn‐derived biodegradable protein, as a multifunctional nanocarrier for sustainable agriculture and packaging. It examines advances in agrochemical delivery, smart packaging, and stimuli‐responsive systems, while addressing scalability, environmental fate, and regulatory barriers.

Innovative Approach to Recycle Lithium‐Ion Battery Electrolytes via Sequential Chemical Processes

Advanced Energy Materials, Volume 15, Issue 46, December 9, 2025.
A chemical separation method is developed to recycle and purify nonaqueous electrolytes from spent lithium‐ion batteries. The new process consists of a sequence of precipitation in tandem with each distillation and solvent‐assisted vacuum extraction to obtain high‐quality electrolyte precursors.

Continuous‐Flow Synthesis of Cyclic Carbonate With Supercritical CO2 Using Polystyrene‐Supported Imidazolium Catalysts

Chemistry – An Asian Journal, Volume 20, Issue 24, December 15, 2025.
A stable and highly active polystyrene‐supported 2‐methylimidazolium chloride was developed for the continuous‐flow synthesis of cyclic carbonates using supercritical CO2. The catalyst delivered a consistent 70%–80% yield over 48 h, achieving a turnover number (TON) of 1900.
