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 ...

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.

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 ...

Spontaneity of nuclear fusion: a qualitative analysis via classical thermodynamics [version 3; peer review: 3 approved]

open access: yesOpen Research Europe, 2021
Background: So far the feasibility of nuclear reactions has been studied only through the evaluation of the reaction rate, which gives us information about the kinetics, while the thermodynamic analysis has been limited to evaluations of the change in ...

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 ...

A millifluidic calorimeter with InfraRed thermography for the measurement of chemical reaction enthalpy and kinetics [PDF]

open access: yes, 2008
The aim of this work is to present an infrared calorimeter for the measurement of the kinetics and the enthalpy of high exothermic chemical reactions. The main idea is to use a millifluidic chip where the channel acts as a chemical reactor.
