Pronounced differences in heart rate and metabolism distinguish daily torpor and short-term hibernation in two bat species

open access: yesScientific Reports, 2022
Torpor, and its differential expression, is essential to the survival of many mammals and birds. Physiological characteristics of torpor appear to vary between those species that express strict daily heterothermy and those capable of multiday hibernation,

Pyrolysis of residual tyres: Exergy and kinetics of pyrogas

open access: yesSouth African Journal of Chemical Engineering, 2022
Around 1.5 billion tyres are produced each year, with a huge percentage ending up in landfills. Residual rubber tyres have a calorific value of 39–42 MJkg−1, making them an appealing candidate for pyrolysis.

Utilization of a CO2 Storage Material: Shape-Controlled Preparation of CaCO3 Microspheres

open access: yesCrystals, 2019
Homogeneous CaCO3 microspheres were controllably synthesized via a simple hydrothermal method without using extraneous additives by Ca(OH)2 saturated solution reacted with CO2 storage material (CO2SM), which was obtained by absorbing CO2 gas in a system ...

The study of CO2 absorption intensification using porous media material in aqueous AMP solution

open access: yesPetroleum, 2018
In this work, the performance of CO2 absorption into aqueous 2-amino-2-methyl-propanol (AMP) solution was investigated by measuring the amount of CO2 in the liquid phase during CO2 absorption process to identify initial CO2 absorption rate.
