Cross-plane heat conduction in thin solid films [PDF]

open access: yes, 2014
Cross-plane heat transport in thin films with thickness comparable to the phonon mean free paths is of both fundamental and practical interest. However, physical insight is difficult to obtain for the cross-plane geometry due to the challenge of solving ...

Fourier Heat Conduction as a phenomenon described within the scope of the Second Law

open access: yes, 2014
The historical development of the Carnot cycle necessitated the construction of isothermal and adiabatic pathways within the cycle that were also mechanically "reversible" which lead eventually to the Kelvin-Clausius development of the entropy function ...

Laser‐Induced Graphene from Waste Almond Shells

open access: yesAdvanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Heat transfer dynamics in the absorber plates of a flat-plate solar collector using both Fourier and revised non-Fourier analyses

open access: yesResults in Engineering
Recent years have seen an increased focus on non-Fourier heat conduction models for simulating microscale and ultrafast transient thermal processes. These models are particularly relevant in scenarios where classical Fourier theory fails to capture non ...

Transport in perturbed classical integrable systems: the pinned Toda chain

open access: yes, 2018
Nonequilibrium and thermal transport properties of the Toda chain, a prototype of classically integrable system, subject to additional (nonintegrable) terms are considered.

Near‐Infrared Emitting Lanthanide Catecholate Giant Single Crystals – Morphology Control and Photon Down‐Conversion

open access: yesAdvanced Functional Materials, EarlyView.
Controlled syntheses of lanthanide coordination polymers based on the dihydroxybenzoquinone (DHBQ) organic linker afforded large single crystals of Ln‐DHBQ CPs (Ln = Yb, Nd). A novel structural variant of Yb‐DHBQ is identified by means of single crystal diffraction analysis.

Flexibility and Dynamicity Enhances and Controls Supramolecular Self‐Assembly of Zinc(II) Metallogels

open access: yesAdvanced Functional Materials, EarlyView.
Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.

Innovative heat flux modeling for enhanced heat transfer efficiency: Conjugate heat transfer analysis with Cattaneo-Vernotte equation incorporating Maxwellian fluid dynamics

open access: yesAin Shams Engineering Journal
A mathematical investigation explored the combined influence of vibration and conjugation on enhancing heat transfer in a laminar oscillatory flow through a heat pipe, also known as the “Dream Pipe”. Explicit solutions for the momentum and heat equations
