Sunlight‐Driven Fixation of CO2 to Cyclic Carbonates Using Carbon Dots as a Photothermal Catalyst

open access: yesExploration, EarlyView.
The first example using carbon dots (CDs) for coupling CO2 with epoxides to generate cyclic carbonates in a metal‐, additive, solvent‐ and electricity input‐free manner under sunlight via photothermal catalytic route is developed. The CDs exhibit highly efficient solar‐to‐thermal conversion with an efficiency of 54%, providing thermal energy for ...

EnzRetro: Enzymatic Retrosynthetic Planning With Site‐Specific Reaction Edits Based on Sequence Generative Architecture

open access: yesExploration, EarlyView.
EnzRetro bridges retrosynthesis planning and enzymatic engineering through site‐specific reaction edits. This end‐to‐end framework integrates pathway synthesis and enzyme identification into a unified process, achieving superior accuracy and enabling the efficient reconstruction of diverse biosynthetic pathways.

Mechanical Behaviour of Vacuum‐Infused GFRP Composites at Elevated Temperatures—Influence of Fibre Architecture

open access: yesFire and Materials, EarlyView.
ABSTRACT This study addresses the influence of fibre architecture on the mechanical properties of vacuum‐infused glass fibre reinforced polymer (GFRP) composites at elevated temperatures (ET). Laminates with three different fibre configurations—unidirectional (UD), bidirectional 0°/90° cross‐ply (BD), and ±45° off‐axis angle‐ply (OA) – were tested in ...

Rheological and Textural Properties of Clean‐Label 3D‐Printed Traditional Thai Dessert

open access: yesFood Bioengineering, EarlyView.
ABSTRACT This study aimed to develop a clean‐label 3D‐printable food ink using a formulation based on Khanom Piak Poon, a traditional Thai dessert, enriched with carrot powder (CP) for enhanced nutritional value. Unlike conventional food printing inks that contain additive hydrocolloids, this ink relies on the natural reactions between starch, sugar ...

Local Polynomial Regression and Filtering for a Versatile Mesh‐Free PDE Solver

open access: yesInternational Journal for Numerical Methods in Fluids, EarlyView.
A high‐order, mesh‐free finite difference method for solving differential equations is presented. Both derivative approximation and scheme stabilisation is carried out by parametric or non‐parametric local polynomial regression, making the resulting numerical method accurate, simple and versatile. Numerous numerical benchmark tests are investigated for

A Fuzzy Framework for Realized Volatility Prediction: Empirical Evidence From Equity Markets

open access: yesJournal of Forecasting, EarlyView.
ABSTRACT This study introduces a realized volatility fuzzy time series (RV‐FTS) model that applies a fuzzy c‐means clustering algorithm to estimate time‐varying c$$ c $$ latent volatility states and their corresponding membership degrees. These memberships are used to construct a fuzzified volatility estimate as a weighted average of cluster centroids.
