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

Scientific 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,

Modeling, prediction and multi-objective optimization of the coal gasification system [PDF]

E3S Web of Conferences, 2021
As global energy demand continues to increase, coal as basic energy still accounts for a significant proportion. Under the pressure of environmental protection, clean and efficient coal utilization technologies are in great demand.

Increased CO2 storage capacity using CO2-foam

International Journal of Greenhouse Gas Control, 2020
Abstract Reduction of the CO2 mobility is beneficial during subsurface sequestration of anthropogenic CO2 in saline aquifers and hydrocarbon reservoirs by mitigating flow instabilities leading to early gas breakthrough and poor sweep efficiency. Injection of CO2 foam is a field-proven technology for gas mobility control.

Elevated CO₂ does not increase eucalypt forest productivity on a low-phosphorus soil [PDF]

, 2017
Rising atmospheric CO2 stimulates photosynthesis and productivity of forests, offsetting CO2 emissions. Elevated CO2 experiments in temperate planted forests yielded ~23% increases in productivity over the initial years.

Pyrolysis of residual tyres: Exergy and kinetics of pyrogas

South 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.

Infrared spectroscopy of solid CO-CO2 mixtures and layers [PDF]

, 2005
The spectra of pure, mixed and layered CO and CO2 ices have been studied systematically under laboratory conditions using infrared spectroscopy. This work provides improved resolution spectra (0.5 cm-1) of the CO2 bending and asymmetric stretching mode ...

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

Crystals, 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 ...
