Effect of Al addition on the thermal properties of lead -tin alloy

open access: yesResults in Materials, 2021
The effect of aluminium addition on the thermal parameters of Pb–Sn alloy was investigated. The technique of Differential Thermal Analysis (DTA) was selected to determine the phase transformation temperatures and the effect of varying heating rates ...

Enthalpy of fusion prediction for the economic optimisation of salt based latent heat thermal energy stores

open access: yesJournal of Energy Storage, 2018
Thermal energy storage represents a cost-effective means of integrating variable, renewable resources into the energy mix. The utilisation of latent heat in addition to sensible can reduce capital costs.

Theory of Solvation-Controlled Reactions in Stimuli-Responsive Nanoreactors [PDF]

open access: yes, 2015
Metallic nanoparticles embedded in stimuli-responsive polymers can be regarded as nanoreactors since their catalytic activity can be changed within wide limits: the physicochemical properties of the polymer network can be tuned and switched by external ...

Thermo-mechanical processing of sugar beet pulp. II. Thermal and rheological properties of thermoplastic SBP [PDF]

open access: yes, 2006
Thermoplastic properties of extruded sugar beet pulp (SBP) are closely linked to water–polymer relationships. DSC analyses of water evaporation, water fusion and biopolymer relaxation according to SBP moisture content gave a more accurate estimation of ...

Solution thermodynamics of methocarbamol in some ethanol + water mixtures

open access: yesQuímica Nova, 2012
Apparent thermodynamic functions, Gibbs energy, enthalpy and entropy of solution and mixing, for methocarbamol in ethanol + water mixtures, were evaluated from solubility data determined at temperatures from 293.15 K to 313.15 K and from calorimetric ...

Thermodynamic properties of L-menthol in crystalline and gaseous states

open access: yesТонкие химические технологии, 2020
Objectives. Menthol causes a cooling sensation and reduces the nerve activity when it is applied locally, ingested, or inhaled. This feature explains its extensive use as both an aromatizer and a flavoring agent in food manufacturing, tobacco industry ...

First and Second Dissociation Enthalpies in Bi-Component Crystals Consisting of Maleic Acid and L-Phenylalanine

open access: yesMolecules, 2021
The energetics of the stepwise dissociation of a A:B2 bi-component crystal, according to A:B2(cr) → A:B(cr) + B(cr) and A:B(cr) → A(cr) + B(cr), was investigated using MA:Phe2 and MA:Phe (MA = maleic acid; Phe = L-phenylalanine) as model systems.

Laser desorption/ionization mass spectrometry of L-thyroxine (T4) using combi-matrix of α-cyano-4-hydroxycinnamic acid (CHCA) and graphene

open access: yesJournal of Analytical Science and Technology, 2022
An optimal combi-matrix for MALDI-TOF mass spectrometry was presented for the analysis of L-thyroxine (T4) in human serum. For the selection of the optimal combi-matrix, several kinds of combi-matrices were prepared by mixing the conventional organic ...
