Atmospheric Chemistry of CFH2CH2CH2CFH2: Kinetics and Mechanism of Reactions With Cl Atoms and OH Radicals

International Journal of Chemical Kinetics, EarlyView.
ABSTRACT The atmospheric chemistry of 1,4‐difluorobutane (CFH2CH2CH2CFH2) was investigated through a kinetic and mechanistic study of the reaction with chlorine (Cl) atoms and hydroxyl (OH) radicals. Using Fourier transform infrared (FTIR) spectroscopy and relative rate methods, the rate constants (k) for the reactions were determined at 298 ± 2 K as k(

General‐Purpose Hexagonal Programmable Photonic Integrated Circuit with a >30 GHz Free Spectral Range

Laser &Photonics Reviews, EarlyView.
A compact and low insertion loss programmable photonic circuit is demonstrated based on a 7‐cell hexagonal waveguide mesh with a large free spectral range (FSR) of 31 GHz for a 6‐gate ring resonator configuration. Vernier rings and a dual‐injected ring configuration are demonstrated on this circuit with a further improved FSR of 93 GHz.

Flame‐Assisted Modification of Glass Wettability: Preliminary Results

Macromolecular Symposia, EarlyView.
ABSTRACT Fog formation and moisture condensation limit the performance of glass surfaces in optical, microfluidic, and sensing applications, where stable transparency under humid conditions is essential. Enhancing surface wettability represents an effective strategy to mitigate these effects; therefore, the development of methods to tailor glass ...

A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

Mathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Investigating Tuberculosis Dynamics Under Various Control Strategies: A Comprehensive Analysis Using Real Statistical Data

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In the present investigation, a mathematical model with vaccination, treatment, and environmental impact under real data is presented. Initially, we present the model without any interventions, followed by an examination of its equilibrium points.
