Fast ion conducting phosphate glasses and glass ceramic composites: Promising materials for solid state batteries

Abstract: Fast ion conducting (FIC) phosphate glasses and glass ceramic composites have gained considerable importance due to their potential applications in the fabrication of solid-state batteries and other electrochemical devices. We, therefore, present an overview on various types of FIC glasses and glass ceramic composites. Silver phosphate glasses doped with different weight percent of lithium chloride (1, 5, 10 and 15 wt.%) were synthesized by melt quenching technique. The Ag2O–P2O5–(15 wt.%) LiCl glass exhibited the maximum electrical conductivity (σ = 8.91 × 10− 5 S cm− 1 at room temperature and 4.16 × 10− 3 S cm− 1 at 200 °C). Using this glass as an amorphous host material, glass–ceramic composites of Ag2O–P2O5–(15 wt.%) LiCl:xAl2O3 (x = 5–50 wt.%) were prepared. The ionic transference number, electrical conductivity, ionic mobility and carrier ion concentration of the synthesized samples were measured. Ag2O–P2O5–(15 wt.%) LiCl:(25 wt.%) Al2O3 composite system exhibited the maximum σ value (σ = 3.32 × 10− 4 S cm− 1 at room temperature and 2.88 × 10− 2 S cm− 1 at 200 °C ). Solid‐state batteries using undoped Ag2O–P2O5 glass, Ag2O–P2O5–(15 wt.%) LiCl glass and glass ceramic composite containing 25 wt.% Al2O3 as electrolytes were fabricated. The open circuit voltage (OCV) values and discharge time of these cells were measured and compared. It is found that the glass ceramic composites show enhanced ionic conduction, better OCV value and discharge characteristics.

Purification of a peroxidase from Solanum melongena fruit juice.

Abstract: Solanum melongena fruit juice contains peroxidase activity of the order of 0.125 IU/mL. A method for the 11-fold purification of the enzyme was developed. The Km values of the peroxidase for the substrates guaiacol and hydrogen peroxide were 6.5 mM and 0.33 mM, respectively. The pH and temperature optima were 5.5 and 84 degrees C, respectively using guaiacol as the substrate. Sodium azide and phenyl hydrazine inhibited the enzyme competitively.

Genome wide in silico characterization of Dof gene families of pigeonpea (Cajanus cajan (L) Millsp.)

Abstract: The DNA binding with One Finger (Dof) protein is a plant specific transcription factor involved in the regulation of wide range of processes. The analysis of whole genome sequence of pigeonpea has identified 38 putative Dof genes (CcDof) distributed on 8 chromosomes. A total of 17 out of 38 CcDof genes were found to be intronless. A comprehensive in silico characterization of CcDof gene family including the gene structure, chromosome location, protein motif, phylogeny, gene duplication and functional divergence has been attempted. The phylogenetic analysis resulted in 3 major clusters with closely related members in phylogenetic tree revealed common motif distribution. The in silico cis-regulatory element analysis revealed functional diversity with predominance of light responsive and stress responsive elements indicating the possibility of these CcDof genes to be associated with photoperiodic control and biotic and abiotic stress. The duplication pattern showed that tandem duplication is predominant over segmental duplication events. The comparative phylogenetic analysis of these Dof proteins along with 78 soybean, 36 Arabidopsis and 30 rice Dof proteins revealed 7 major clusters. Several groups of orthologs and paralogs were identified based on phylogenetic tree constructed. Our study provides useful information for functional characterization of CcDof genes.
