A mathematical model has been developed to study the magnetohydrodynamic (MHD) flow of viscous fluid due to a nonlinear stretching cylinder. The flow is discussed in the presence of velocity and thermal slip conditions. Effects of viscous dissipation and

Equilibrium Theory for a Particle Pulled by a Moving Optical Trap
The viscous drag on a colloidal particle pulled through solution by an optical trap is large enough that on experimentally relavant time scales the mechanical force exerted by the trap is equal and op- posite the viscous drag force.

Sustainable Catalyst‐Free PLG Networks: Recyclability, Biodegradability, and Functional Performance
A catalyst‐additive free covalent adaptable network is developed from star‐shaped poly(lactide‐co‐glycolide) cross‐linked with pyromellitic dianhydride, enabling internal carboxylic acid‐driven transesterification. The resulting biodegradable network exhibits mechanical robustness (Young's modulus ≈1.6 GPa), complete recyclability, rapid biodegradation

Sub-photospheric turbulence as a heating mechanism in gamma-ray bursts
We examine the possible role of turbulence in feeding the emission of gamma-ray bursts (GRBs). Turbulence may develop in a GRB jet as the result of hydrodynamic or current-driven instabilities.

Nanolayer‐Encapsulated Stretchable Liquid‐Metal Sheets for Thermal Management
A stretchable liquid metal sheet with both high thermal conductivity and mechanical flexibility is developed. Its trilayer structure, comprising copper‐particle‐dispersed gallium liquid metal encapsulated by styrene‐butadiene‐styrene nanosheets, shows 40.4 W m−1 K−1 conductivity, elongation exceeding 200%, and retention of 96% of its initial ...

Nanothermometry in Living Cells: Physical Limits, Conceptual and Material Challenges
Heat and temperature are fundamental to life. When nanothermometers began probing regions as small as a living cell, they triggered controversial claims of large intracellular temperature gradients. We review physical constraints energy‐conservation, entropy production, thermodynamic fluctuations, and molecular dynamics.

Effect of Variable Gravity on Darcy Flow with Impressed Horizontal Gradient and Viscous Dissipation
The effect of variable gravity on the free convection in a horizontal porous layer with viscous dissipation is investigated. The bottom boundary is taken as adiabatic and there is a non-uniform temperature distribution along the upper boundary.

Variable properties of MHD third order fluid with peristalsis
This article addresses the impact of temperature dependent variable properties on peristaltic flow of third order fluid in a symmetric channel. The MHD fluid and viscous dissipation effects are taken into account.
