Temperature‐Dependent Investigation of the S‐Branch Raman Linewidth in CO2 via Time‐Resolved Rotational CARS

Journal of Raman Spectroscopy, EarlyView.
We studied the temporal evolution of the rotational coherent anti‐Stokes Raman scattering (RCARS) signal of CO2 to determine the S‐branch Raman linewidth, which is an essential parameter for accurate spectral modeling in RCARS gas‐phase diagnostics. We found a non‐monotonic J‐dependence of the S‐branch Raman linewidth not accounted for in previously ...

Laser Absorption Shock Tube Study of C1 to C4 n‐Alkyl Formate Pyrolysis

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT n$n$‐Alkyl formates are considered as potential alternative fuels or fuel additives. While their oxidation chemistry has been investigated intensely, their pyrolysis chemistry requires more experimental insights. The present work utilizes shock tube experiments in combination with infrared laser absorption measurements to obtain information ...

Tautomerization Kinetics of Thiouracils at Low Temperatures Driven Solely by Quantum‐Mechanical Tunnelling: Predictions of Suitable Candidates for Future Experiments

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT In the past two decades numerous experiments have been conducted on the kinetics of reactions occurring at low temperatures on inert matrices. In particular, unimolecular proton‐transfer photo‐reactions of compounds containing a carbon–sulfur double bond, or thione group C═S, can lead to the formation of higher energy isomers or tautomers with

Optically Bound Rapid Plasmonic Nanorod Dimers: Anisotropic Dynamics Driven by Light‐Fluidic Cooperation

Laser &Photonics Reviews, EarlyView.
Optically confined gold nanorods exhibit cooperative light‐driven dynamics, forming mobile end‐to‐end dimers with orientation‐dependent propulsion. Using structured laser traps and an opto‐thermo‐hydrodynamic model, we uncover how optical binding, polarization‐induced torque, and near‐surface hydrodynamics govern their motion.

Static and Dynamic Analysis of Porous Gas Bearings Lubricated With Air, Refrigerant R‐134a, Helium and Hydrogen

Lubrication Science, EarlyView.
ABSTRACT Porous gas bearings (PGBs) enable high‐speed, oil‐free operation in modern rotating machinery. This study develops a coupled thermo‐hydrodynamic (THD) model for a cylindrical porous gas bearing lubricated with four working fluids—air, R‐134a, helium and hydrogen.

Ellipsoid‐Based Interval‐Type Uncertainty Model Updating Based on Riemannian Manifold and Gaussian Process Model

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Modern engineering systems require advanced uncertainty‐aware model updating methods that address parameter correlations beyond conventional interval analysis. This paper proposes a novel framework integrating Riemannian manifold theory with Gaussian Process Regression (GPR) for systems governed by Symmetric Positive‐Definite (SPD) matrix ...

Enhancing Neural Stem Cell Proliferation Using Polyurethane/CNT Scaffolds Functionalized With Liposomal Hesperidin for Neural Tissue Engineering

Nano Select, EarlyView.
A multifunctional electrospun scaffold combining polyurethane, carbon nanotubes, and liposomal hesperidin supports neural stem cell survival, adhesion, and expansion. This platform enhances conductivity, mechanical strength, and hydrophilicity while mimicking the native neural environment.
