CFD modeling and sensitivity‐guided design of silicon filament CVD reactors

AIChE Journal, EarlyView.
Abstract Filament‐based chemical vapor deposition (CVD) for silicon (Si) coatings is often treated as an adaptation of planar deposition. But this overlooks fundamental shifts in transport phenomena and reaction kinetics. In filament CVD, the filament acts as a substrate, heat source, and flow disruptor simultaneously. In this work, we ask: What really

SigmaFormer: Augmenting transformer encoders with COSMO sigma profiles for pure component property prediction

AIChE Journal, EarlyView.
Abstract Transformer‐based molecular models pretrained on SMILES strings demonstrate strong performance in property prediction. However, these model often lack explicit integration of molecular surface charge distributions that govern intermolecular interactions such as hydrogen bonding and polarity.

Resolving passive heat transfer and phase‐change heat in cryogenic CO2 deposition (Desublimation) from CO2/N2 mixtures

AIChE Journal, EarlyView.
Abstract In cryogenic CO2 desublimation systems where phase change dominates both heat transfer and separation, conventional lumped thermal‐resistance treatments embed interfacial latent heat into an overall heat‐transfer coefficient, obscuring how phase‐change heat is partitioned between the gas phase and the coolant and limiting diagnostic insight ...

Measuring Local Exothermic Effects During the Oxidative Coupling of Methane Using Operando Luminescence Thermometry

Angewandte Chemie, EarlyView.
Operando luminescence thermometry shows that the local catalyst temperature can exceed the set oven temperature by almost 250°C during the exothermic oxidative coupling of methane process. We demonstrate how the reactor dimensions, catalyst grain size, and reactant feed mixture affect the local temperature.

A Robust Deep Temporal Causal Discovery Platform for Single‐Cell Gene Regulatory Network Reconstruction

Advanced Intelligent Discovery, EarlyView.
scTIGER2.0 is a deep‐learning framework that infers gene regulatory networks from single‐cell RNA sequencing data. By integrating correlation, pseudotime ordering, deep learning and bootstrap‐based significance testing, it reduces false positives and reveals directional gene interactions.

Mechanochemistry Meets Catalysis: Metal Complexes for Greener Organic Transformations

Angewandte Chemie, EarlyView.
Mechanochemistry is redefining metal catalysis by controlling catalyst formulation, speciation, and deployment. This Review shows how milling, LAG, RAM, and TSE enable rapid metal‐complex assembly, distinctive catalytic manifolds, and scalable synthesis beyond solution chemistry.

IRF‐1 modulates hepatic ferroptosis and aggravates liver ischemia/reperfusion injury via DYRK1α

Animal Models and Experimental Medicine, EarlyView.
IRF‐1 modulates hepatic ferroptosis and aggravates liver ischemia/reperfusion injury via DYRK1α. Abstract Background The purpose is to define the contribution of the interferon regulatory factor‐1–dual‐specificity tyrosine phosphorylation‐regulated kinase 1α (IRF‐1–DYRK1α) axis to hepatocellular ferroptosis during liver ischemia/reperfusion injury ...

Biological N2 fixation in the upwelling region off NW Iberia: magnitude, relevance and main players

, 2016
Conference communicationThe classical paradigm about marine N2 fixation establishes that this process is mainly constrained to oligotrophic tropical and subtropical regions, and attributed mostly to the filamentous cyanobacterium Trichodesmium.

Graphdiyne as a Hole‐Transport Channel in Carbon Nitride Heterojunctions for Synergistic CO2 Reduction and γ‐Butyrolactone Synthesis

Angewandte Chemie, EarlyView.
A fully metal‐free heterojunction constructed from graphdiyne (GDY) and polymeric carbon nitride (PCN) enables efficient coupling of CO2 reduction and tetrahydrofuran oxidation. GDY serves as a hole‐transport channel, establishing a built‐in electric field that drives spatial charge separation. The optimized catalyst achieves near‐unity selectivity for
