Carbon Dioxide Chemical Absorption Using Diamines with Different Types of Active Centers

open access: yesSeparations, 2022
The present research analyzes chemical solvents based on the use of diamines (Ethylenediamine-EDA, 1,2-Dimethylethylenediamine-DMEDA and Tetramethylethylenediamine-TMEDA) for carbon dioxide absorption, taking into account the type of amino centers in the

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

X-ray Absorption Fine Structure in Embedded Atoms

open access: yes, 1994
Oscillatory structure is found in the atomic background absorption in x-ray-absorption fine structure (XAFS). This atomic-XAFS or AXAFS arises from scattering within an embedded atom, and is analogous to the Ramsauer-Townsend effect.

Transferrin receptor 1‐mediated iron uptake supports thermogenic activation in human cervical‐derived adipocytes

open access: yesFEBS Letters, EarlyView.
In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

Research Progress on Carbon Capture and Utilization Technology in Steel Industry

open access: yes发电技术
ObjectivesThe control of greenhouse gas emissions, mainly CO2, under the “carbon peak and carbon neutrality” target has received high attention. In 2023, China’s CO2 emissions ranked first in the world, with 12.6 billion tons.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Experimental and Application Research of Novel Polyamine-Based CO2 Absorbents in Gas-Fired Power Plants

open access: yes发电技术
ObjectivesCurrently, chemical absorption CO2 capture technology used in post-combustion is rarely applied in large-scale decarbonization projects in gas-fired power plants due to its high operational energy consumption and total costs. In order to reduce

The effect of intensive traffic on soil and vegetation risk element contents as affected by the distance from a highway

open access: yesPlant, Soil and Environment, 2012
The potential effect of intensive traffic on detrimental element contents in soil and vegetation was investigated in the vicinity of a selected section (1 km) of a highly frequented highway as affected by the distance from the roadway (1 m, 35 m, and 70 ...
