The gas-phase chemistry of carbon chains in dark cloud chemical models

, 2013
We review the reactions between carbon chain molecules and radicals, namely Cn, CnH, CnH2, C2n+1O, CnN, HC2n+1N, with C, N and O atoms. Rate constants and branching ratios for these processes have been re-evaluated using experimental and theoretical ...

A Review on Microreactor Design for Effective Fischer–Tropsch Process Intensification

Advanced Materials Technologies, EarlyView.
Design strategies for effective Fischer–Tropsch process intensification are summarized based on experimental and simulation experiences. Recommendations for catalyst loading of packed‐bed and wash‐coated microchannel, microtube, micromonolith, and microstructured reactors are discussed.

Disrupting J‐Aggregation in Triazatruxene Dimers to Develop Responsive Luminescent Inks for Anti‐Counterfeiting Applications

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study investigates the stimulus‐responsive behavior of trialkylated triazatruxene dimers for third‐generation luminescent security inks. In particular, the derivative with flexible dodecyl chains displays high‐contrast, reversible color changes upon heating or shear, driven by liquid crystalline phase transitions and involving J ...

Harnessing Carbenoid Reactivity From Imidazoles and Oxiranes

Advanced Synthesis &Catalysis, EarlyView.
The combination of azole compounds and oxiranes exhibits carbenoid reactivity at elevated temperatures, as demonstrated by the successful benzoin condensation of aromatic aldehydes. Using this catalytic system to polymerize bifunctional aldehyde/oxirane monomers yields thermosets with glass transition temperatures above 100°C.

The Core–Shell Conformational Space of Compartmentalized Single‐Chain Nanoparticles by Paramagnetic and Hyperpolarized NMR Spectroscopy

Advanced Science, EarlyView.
Combinations of integrative NMR spectroscopy and molecular dynamics simulations reveal the internal structural dynamics of single‐chain nanoparticles. Abstract Single‐chain nanoparticles (SCNPs) are formed by the collapse of individual polymer chains, generating entities comparable to proteins in size, internal structure, and function.

Regulation of Excitonic Behavior in Defective Acetylenic Polymers Enables Mechanism Switching in O2 Activation for Enhanced Water Decontamination

Advanced Science, EarlyView.
A molecular defect‐mediated charge accumulation strategy is developed to regulate the exciton behavior for selective molecular oxygen (O2)activation in poly(1,3,5‐triethynylbenzene) (PTEB). Artificial internal electric field (IEF) constructed in defective PTEB provides internal driving force to steer the directed migration of charge carriers, thereby ...

An Opto‐Actuated Hydrogel for Cell Mechanoactuation and Real‐Time Force Monitoring

Advanced Science, EarlyView.
Researchers developed a mechanoactuated hydrogel interface where nanomachines exert forces on adhesion receptors and allow monitoring of traction force responses in real time. They demonstrate reversible talin recruitment, enhanced F‐actin polymerization, and a reduction in cell traction force when force is locally applied to focal adhesions of ...

Soybean Auxin Transporter PIN3 Regulates Nitrate Acquisition to Improve Nitrogen Use and Seed Traits

Advanced Science, EarlyView.
Xu et al. discovers that switching off auxin transporters in soybean, PIN3a and PIN3b, disrupts auxin flow; this triggers ARF‐STF3/4 signal cascade to activate the nitrate importer NPF2.13 and soil nitrogen acquisition. Multi‐year field trials show edited soybeans maintain yield with higher oil content, offering a potential genetic route to improve ...

Host‐Directed Antiviral Activity of SB2960 Through Selective Induction and Remodeling of Stress Granules

Advanced Science, EarlyView.
Amid the ongoing threat of emerging viral pathogens, host‐directed antivirals offer a strategy to overcome viral mutation and drug resistance. SB2960, a small‐molecule inducer of stress granules (SGs), exhibits potent broad‐spectrum antiviral activity with minimal cytotoxicity.
