This document summarizes a study on the inhibition of human alkaline phosphatases by vanadate. The key findings are: 1) Vanadate (orthovanadate) was found to be a potent competitive inhibitor of purified alkaline phosphatase from human liver, intestine and kidney, with a Ki of less than 1 microM. 2) The inhibitory effect of vanadate was reversed and full enzymatic activity was restored in the presence of 1mM adrenaline. 3) Phosphate and vanadate were found to compete for the same binding site on the enzyme.

Abstract
The mild combustion synthesis of cobalt vanadate involving the reaction of V2O5, Co(NO3)2
and glycine as starting materials is reported.
The synthesized material is annealed at 550 8C and characterized by means of X-ray diffraction
(XRD), cyclic voltammetry, and galvanostatic
charge–discharge cycling techniques. XRD analysis indicates that the structure of the
synthesized cobalt vanadate is amorphous. The initial
delivered capacity is _275 mAh g_1 in a Li//CoV2O5 cell at a current density of 0.05 mA cm_2
when cycled between 2 and 4 V using 1 M
LiClO4 in propylene carbonate as electrolyte. The capacity remains stable even after 10 cycles.
The cobalt vanadate prepared by this new
synthetic route is, therefore, a potential candidate for lithium secondary batteries.

1. Introduction
Rechargeable lithium batteries have been the focus of
attention since the 1980s as they offer high voltage, good
low temperature performance, easy handling, etc. [1,2].
Moreover, the batteries find use in a variety of applications,
viz. medical implants, cell-phones, electronic toys, electric
vehicles [3,4]. Many workers around the world are pursuing
extensive research for the development of high-voltage and
high-capacity positive-electrode (cathode) materials for use
in such batteries [5,6]. Possible cathode materials include
lithiated transition metal oxides, vanadium oxides, manganese
oxides, molybdenum oxides, and titanium sulfides
[7,8]. Among these materials, vanadium oxides [9,10] are
attractive in view of their high lithium-storage capabilities
and, therefore, high capacities.

Abstract
Bismuth Vanadate (BiVO4) photocatalyst was synthesized by precipitation methods. Two different sources of bismuth namely
bismuth acetate and bismuth nitrate pentahydrate were used. The bismuth solutions were mixed with ammonium metavanadate
solution before being titrated against ammonium hydrogen carbonate solution. The precipitate formed using bismuth acetate (B1)
was calcined at 450 oC and that of bismuth nitrate was calcined at 450oC (B2) and 300oC (B3) under air flow for 4h.The
resulting powder were characterized by XRD, FESEM, IR and its surface area. XRD pattern analysis showed that all BiVO 4
sample produced are of monoclinic phase and the FESEM images showed that the particles were agglomerated. The surface area
of BiVO4 produced from bismuth nitrate pentahydrate was higher (3.9 m2/g) than that produced from bismuth acetate (2.7 m2/g).
Photocatalytic activities of the synthesized BiVO4 were evaluated by photodegrading Methylene Blue dye (MB) under visible

4. light irradiation. The highest photocatalytic activity was observed when using B3 as photocatalyst with percentage removal of
34%.

Abstract
Orthovanadate was shown to be a potent competitive inhibitor (Ki less than 1 microM) of purified
alkaline phosphatase from human liver, intestine of kidney. Inhibition was reversed and full enzymic
activity restored in the presence of 1mM-adrenaline. Phosphate and vanadate competed for the same
binding site on the enzyme.
