Phosphate doped hard carbons have shown a significant capacity increase accompanied by an additional plateau in its voltage profile. The work reveals the co-contribution of oxygen atoms phosphate and carbon for Na-ion storage.

A basic alumina-spinel low cement castable (LCC) composed of sintered bauxite, reactive alumina, calcined alumina, calcined magnesia, microsilica, and high alumina refractory cement was prepared (castable A) to which 5% sodium hexa-meta phosphate was later added (castable B) to prepare samples for heat treatment at 110ºC, 900ºC, and 1400ºC. Bulk Density (BD), Apparent Porosity (AP), and Cold Cr...

This study evaluates the arsenic adsorption behavior of Fe-exchanged smectite and phosphate-bound kaolinite, in soil, tap water double distilled presence competing anions such as silicate, phosphate, sulfate, at variable pH values. The maximum amounts As adsorbed soil are 620.6 607.6 µg g–1 5 by respectively. pH-modified Freundlich equation fits well (R2 > 0.96) to data, distinguishing effect o...

lamerin microspridia (lbms) isolated from lamerin breed of the silkworm, bombyx mori, l. and the standard strain nosema bombycis, were induced to germinate artificially by two-step procedure. fresh percoll purified spores were activated by incubating them in potassium hydroxide solution (koh) (ph 11.00) and germinated artificially by using phosphate buffer saline (pbs), (ph 7.00). germinated sp...

an efficient method for the friedel–crafts acylation of a wide range of aromatic compounds in good to excellent yields under solvent-free conditions, using iron zirconium phosphate (zpfe) was investigated. the catalyst is easy to prepare and shows interesting catalytic properties. the catalyst was characterized by some instrumental techniques such as xrd, icp-oes, sem and tem. a wide variety of...

results the optimal conditions were considered to perform elisa. comparison between results obtained from optimized elisa kit and commercial elisa kit showed a good agreement. background haemophilus influenzae type b (hib) infection has high morbidity and mortality rate, especially in children under 5 years of age. enzyme-linked immunosorbent assay (elisa) technique is the most used method to d...

conclusions: in the current study, quality of life was correlated with serum calcium level, calcium-phosphate product, and serum pth level, while hospitalization was correlated only with serum phosphorus level. however, quality of life was inversely correlated with hospitalization. background: significant impairment in health-related quality of life (hrqol) among dialysis patients could be part...
