Effect of styrene-butadiene-styrene copolymer on the aging resistance of asphalt: An atomistic understanding

Frontiers of Structural and Civil Engineering 2021, Volume 15, Issue 5, Pages 1261-1276 doi: 10.1007/s11709-021-0761-5

Abstract: reveal the potential influence of styrene-butadiene-styrene (SBS) polymer modification on the anti-agingperformance of asphalt, and its mechanism, we explored the aging characteristics of base asphalt andThe results illustrate that the SBS asphalt is more susceptible to oxidative aging than the base asphaltIn addition, SBS polymer degrades into small blocks during aging, thus counteracting the hardening ofaged asphalt and partially restoring its low-temperature cracking resistance.

the characterization of pore structures and permeability of diesel contaminated clays under different aging

Frontiers of Structural and Civil Engineering Pages 1264-1280 doi: 10.1007/s11709-023-0921-x

Abstract: to characterize the pore structures and investigate the permeability characteristics of clay after agingThe results of the MIP tests showed that aging leads to reductions in porosity and average diameter,The XRμCT analysis yielded consistent results; it showed that aging renders pores more spherical andMechanistic analysis showed that aging weakens interparticle cohesion; this causes large agglomeratesBoth aging and diesel content can weaken the permeation characteristics of soil.

Insights into influence of aging processes on zero-valent iron modified biochar in copper(II) immobilization

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 7, Pages 880-892 doi: 10.1007/s11705-022-2282-8

Abstract: by natural forces after entering into the environment, while there are seldom studies reported the agingIn this work, the hydrogen peroxide and hydrochloric acid solution were applied to simulate aging conditionsAfter aging, the decreasing of capacity could be mainly attributed to the inhibition of ion-exchangeMoreover, the plant growth and soil leaching experiments also proved the effects of aging treatment,reduced the inhibition of copper(II) bioavailability and increased the mobility of copper(II) after aging

Role of brown adipose tissue in metabolic syndrome, aging, and cancer cachexia

Meng Dong, Jun Lin, Wonchung Lim, Wanzhu Jin, Hyuek Jong Lee

Frontiers of Medicine 2018, Volume 12, Issue 2, Pages 130-138 doi: 10.1007/s11684-017-0555-2

Abstract:

Brown adipose tissue (BAT) plays a fundamental role in maintaining body temperature by producing heat. BAT that had been know to exist only in mammals and the human neonate has received great attention for the treatment of obesity and diabetes due to its important function in energy metabolism, ever since it is recently reported that human adults have functional BAT. In addition, beige adipocytes, brown adipocytes in white adipose tissue (WAT), have also been shown to take part in whole body metabolism. Multiple lines of evidence demonstrated that transplantation or activation of BAT or/and beige adipocytes reversed obesity and improved insulin sensitivity. Furthermore, many genes involved in BAT activation and/or the recruitment of beige cells have been found, thereby providing new promising strategies for future clinical application of BAT activation to treat obesity and metabolic diseases. This review focuses on recent advances of BAT function in the metabolic aspect and the relationship between BAT and cancer cachexia, a pathological process accompanied with decreased body weight and increased energy expenditure in cancer patients. The underlying possible mechanisms to reduce BAT mass and its activity in the elderly are also discussed.
