Superior photocatalytic activity of Cu doped NiWO4 for efficient degradation of benzene in air even under visible radiation by Tri N.L.M.

“…The obtained experimental result indicated that photocatalytic performance of the prepared Cu-NiWO4 materials were greater than that of the pure NiWO4. This was because Cu effectively acted as novel dopant, which not only affected valence band (VB) top and conduction band (CB) bottom of NiWO4 but also formed a medium energy level between CB and VB of the NiWO4 to decrease its energy band gap and electron-hole recombination rate. …”

AMPK Activation Attenuates Albumin-induced Alterations in Renal Tubular Cells In Vitro by Allouch, Soumaya

“…Moreover, higher concentrations of albumin, particularly 30 mg/ml, caused severe induction of ER stress and EMT, marked by 20-fold increase in CHOP and 6-fold increase in a-SMA respectively. Similarly, the phosphorylation of AKT and P70S6K (a downstream target of mTOR) was increased by more than 1.5-fold in cells subjected to albumin treatment. …”
