Erythrocyte plasma membrane potential: Past and current methods for its measurement
(Springer, 2019-12)
The plasma membrane functions both as a natural insulator and a diffusion barrier to the movement of ions. A wide variety of proteins transport and pump ions to generate concentration gradients that result in voltage ...
Tungstophosphoric acid heterogenized onto NH4NH4 ZSM5 as an efficient and recyclable catalyst for the photocatalytic degradation of dyes
(Sociedade Brasileira de Química, 2015-03-05)
Materials based on tungstophosphoric acid (TPA) immobilized on NH4ZSM5 zeolite were prepared by wet impregnation of the zeolite matrix with TPA aqueous solutions. Their concentration was varied in order to obtain TPA ...
