Microtubule-targeting agents (MTAs), widely used as biological probes and chemotherapeutic drugs, bind directly to tubulin subunits and "kinetically stabilize" microtubules, suppressing the characteristic self-assembly process of dynamic instability. However, the molecular-level mechanisms of kinetic stabilization are unclear, and the fundamental thermodynamic and kinetic requirements for dynam...

We introduce dual kinetic chronoamperometry, in which reciprocal relations are established between the kinetic curves of electrochemical reactions that start from symmetrical initial conditions. We have performed numerical and experimental studies in which the kinetic curves of the electron-transfer processes are analyzed for a reversible first order reaction. Experimental tests were done with ...

   In the present study, CeO2/Fe2O3 nanocomposite was prepared by co-precipitation method and its application was investigated for arsenic removal from water. Characterization of the nano sized adsorbent particles was carried out using SEM and XRD techniques. Systemic adsorption experiments were performed in batch systems and the optimum conditions were obtained. The effects of p...

The kinetics of reaction between 4-methylaniline (1), dimethyl acetylenedicarboxylate (2) and formaldehyde (4) has been theoretically investigated to gain further insight into the reaction mechanism. The results of theoretical calculations were achieved using the ab initio method at the HF/6-311g (d, p) level of theory in gas phase. The mechanism of this reaction had 5 steps. Theoretical kineti...

Delineating the kinetic and thermodynamic factors which contribute to the stability of transmembrane β-barrels is critical to gain an in-depth understanding of membrane protein behavior. Human mitochondrial voltage-dependent anion channel isoform 2 (hVDAC-2), one of the key anti-apoptotic eukaryotic β-barrel proteins, is of paramount importance, owing to its indispensable role in cell survival....

Nickel (Ni) as a heavy metal due to its toxicity should be removed from wastewater and aquatic environments  using  efficient  technology.  The  aim  of this  study  was  to  remove  Ni  from  an aqueous  solution  using  palm  leaf  ash  produced  in  a  furnace.  To  do  so,  kinetic  and thermodynamic experiments were conducted on the adsorption process. Moreover, the effect of time, pH, ads...

In this research, a high porous silicate mining waste that was prepared from Syah Kamar Polymetal Porphyry mine in order to malachite green dye (MG) removal has been applied. The characterization of this natural mineral was determined using the XRD, XRF, SEM and FT-IR analysis. The MG adsorption onto high porous activated waste was studied based on the parameters of pH, temperature, adsorbent d...
