Energy performance based optimization of building envelope containing PCM combined with insulation considering various configurations

open access: yesEnergy Reports, 2023
Phase change material (PCM) is considered as a promising solution for reducing heating and cooling energy consumption by integrating them into the building envelope, which in turn reduces CO2 emissions.

Hamiltonian Thermodynamics [PDF]

open access: yesNelineinaya Dinamika, 2020
It is believed that thermodynamic laws are associated with random processes occurring in the system and, therefore, deterministic mechanical systems cannot be described within the framework of the thermodynamic approach. In this paper, we show that thermodynamics (or, more precisely, a thermodynamically-like description) can be constructed even for ...

Effect of small-size space porous flexible PVC material on propane deflagration

open access: yesAIP Advances, 2022
The effect of porous flexible polyvinyl chloride (PVC) barriers on the kinetic properties of propane explosions is investigated based on fluid dynamics and combustion-related theory. Furthermore, using small-sized cylindrical pipes, separate experimental

Descriptive thermodynamics [PDF]

open access: yesPhysica A: Statistical Mechanics and its Applications, 2006
Thermodynamics (in concert with its sister discipline, statistical physics) can be regarded as a data reduction scheme based on partitioning a total system into a subsystem and a bath that weakly interact with each other. The ubiquity and applicability of the scheme chiefly derives from that of partitioning protocols in experiments and observations ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties

open access: yesFEBS Letters, EarlyView.
A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

A methionine‐lined active site governs carbocation stabilization and product specificity in a bacterial terpene synthase

open access: yesFEBS Letters, EarlyView.
This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These
