Upon liver injury, HSCs undergo an activation process by which they lose vitamin A and acquire a myofibroblast-like phenotype, with increased synthesis of collagen I, α-smooth muscle actin and secretion of pro-fibrogenic factors like CTGF and TGF-β.
For the example, the lymphocytes undergo an activation process, aided by the interaction with dendritic cells [19], that involves many short and long living contacts between lymphocytes.
We observe that the S1 → S0 decay kinetics at higher temperatures do not follow a single-exponential law and the ISC rate shows a temperature dependence that cannot be rationalized by a single activation process, suggesting the presence of a complex landscape of configurational energies.
A novel high-performance porous carbon material, nickel-doped magnolia-leaf-derived porous carbon (Ni/MPC), is synthesized by a KOH activation process and nickel-doping strategy.
A hybrid carbon materials with three dimensional network carbon nanotubes in activated carbon was prepared by an in situ activation process.
The investigation pointed out that the HTS-V catalyst presents good textural and morphological properties, which are not deeply affected by the activation process (sample HTS-A).
The surface-modified 3D rGO by steam activation process has a large surface area and abundant defect sites, which serve as active sites to uniformly grow Co/CoOx nanoparticles.
This work presented an unconventional mesopore carbon nanomesh (MCNM), featured with numerous evenly distributed in plane micro/mesopores, which was obtained by a novel explosion assisted activation process employing carboxymethylcellulose sodium (CMCS) as the carbon precursor while potassium nitrate (KNO3) acts as both an explosive and activating reagent.
The textural properties of the carbons are tunable by the activation process, yielding controlled levels of micro and mesoporosity.
The signaling specificity achieved by the activation process of GPCRs is determined not only by the lowest energy receptor state as in the crystal structure but also by the range of nearly degenerate conformational states that the receptor explores.
