An improved theory for calculating leaf gas exchange more precisely accounting for small fluxes
gas exchange leaf von Caemmerer and Farquhar (vCF)
2023/12/8
The widely used theory for gas exchange proposed by von Caemmerer and Farquhar (vCF) integrates molar fluxes, mole fraction gradients and ternary effects but does not account for cuticular fluxes, for...
Advanced nanocellulose-based gas barrier materials: Present status and prospects
Nanocellulose Gas barrier Layer-by-layer materials Composites Biomaterials
2023/12/7
Nanocellulose based gas barrier materials have become an increasingly important subject, since it is a widespread environmentally friendly natural polymer. Previous studies have shown that super-high ...
Xylem embolism spread is largely prevented by interconduit pit membranes until the majority of conduits are gas-filled
drought optical vulnerability pit membranes water relations xylem transport
2023/11/30
Xylem embolism resistance varies across species influencing drought tolerance, yet little is known about the determinants of the embolism resistance of an individual conduit. Here we conducted an expe...

To study the degradation of thermosetting polymers, we apply a novel method to simultaneously study the chemical structural changes and network topology: evolved gas analysis-mass spectrometry combine...
Synthesis of flower-like porous MgO microspheres via a gas-liquid interfacial reaction
Interfacial reaction Basic magnesium carbonate Hierarchical porous structure MgO Adsorption
2023/6/21
The flower-like porous MgO was obtained via a interfacial reaction following by further calcination. In the interfacial reaction, flower-like basic magnesium carbonate microspheres (precursor) were pr...
Economic evaluation and environmental assessment of shale gas dehydration process
Shale gas Dehydration Optimization Hybrid LCI model Input-output model
2023/6/19
Triethylene glycol (TEG) is widely applied to the removal of water in shale gas. This study presents a framework of economic evaluation and environmental assessment for two TEG-based dehydration appro...
Optimization of shale gas sweetening process coupling with claus process based on energy synthesis
gas sweetening claus process energy synthesis
2023/6/19
As a sort of emerging unconventional energy, shale gas has extensive market outlook by virtue of its enormous reserves, and concerns for shale gas exploitation and processing have been raised nowadays...
Liquid film transport around Taylor bubble in a microchannel with gas cavities
Microchannel Gas-liquid Taylor flow Gas cavity Liquid film
2023/3/1
In Taylor flow, the low velocity in liquid film around the bubbles limits the mass transfer between the bubble body and liquid phase. To overcome this deficiency, a cross-junction Microchannel with ga...
Effect of vapor pressure deficit on gas exchange in wild-type and abscisic acid-insensitive plants
ABA-signaling Drought stress HOS15 OST1 ABI1/2 Protein degradation and stability
2024/2/28
Stomata control the gas exchange of terrestrial plant leaves, and are therefore essential to plant growth and survival. We investigated gas exchange responses to vapor pressure deficit (VPD) in two gr...

secondary forests over-mature forests Korean pine plantation greenhouse gas fluxes global warming potential
2024/2/29
This study aimed to evaluate the seasonal variations of Greenhouse Gas fluxes (CH4, CO2, and N2O), Greenhouse Gas (GHG) emissions, and Global Warming Potential (GWP) over the extent of the regions and...
Comparison of diferent aroma active compounds of Sichuan Dark brick tea (Camellia sinensis) and Sichuan Fuzhuan brick tea using gas chromatography–mass spectrometry (GC–MS) and aroma descriptive profle tests
aroma active compounds Sichuan Dark brick tea Sichuan Fuzhuan brick tea GC–MS aroma descriptive profle tests
2024/7/31
Sichuan dark brick tea (Camellia sinensis) and Sichuan Fuzhuan brick tea have signifcantly diferent aroma characteristics although both of them have almost the same processing methods. Thus, these two...
Characteristics of annual greenhouse gas flux and NO release from alpine meadow and forest on the eastern Tibetan Plateau
