The SrBixAlxFe12-2xO19 (x = 0.0–1.0) nano-hexaferrites were prepared via facile micro-emulsion methodand ferroelectric, dielectric, magnetic, photocatalytic and antibacterial properties were investigatedbased on doping contacts. The XRD analysis confirmed the hexagonal single-phase material with P63/mmc space group. P-E loops indicated the higher polarization and coercivity values for doped materials. VSM results showed that maximum and remnant magnetizations were quite high for undoped materialwhile coercivity was low than doped hexaferrite. Optical band gap was reduced to 1.63 eV from 2 eV(pristine) for highly doped composition. PL intensity showed a sharp decline with doping, which indicatedthe better inhibition of charge carriers on doping. The photo-catalytic activity of pristine and thedoped SrBixAlxFe12-2xO19 was investigated using Crystal Violet and Rhodamine B dyes under solar irradiation. SrAlxBixFe12-2xO19 (x = 1.0) exhibited improved catalytic efficiency and up to 83 and 86 (%) removalof CV and RhB dyes with rate constant of 0.047 and 0.048 (min1), respectively. Highly doped ferrite alsoshowed enhanced bactericidal action against S. aureus and E. coli strains. Superior mineralization of textiledyes and good antimicrobial activity of Bi and Al doped strontium nano-hexaferrites make such materialas crucial candidate for solar light responsive photocatalytic and antimicrobial applications.

Genetic and Molecular Control of Floral Organ Identity in Cereals
Ali, Zulfiqar,Raza, Qasim,Atif, Rana Muhammad,Aslam, Usman,Ajmal, Muhammad,Chung, Gyuhwa MDPI AG 2019 INTERNATIONAL JOURNAL OF MOLECULAR SCIENCES Vol.20 No.11
<P>Grasses represent a major family of monocots comprising mostly cereals. When compared to their eudicot counterparts, cereals show a remarkable morphological diversity. Understanding the molecular basis of floral organ identity and inflorescence development is crucial to gain insight into the grain development for yield improvement purposes in cereals, however, the exact genetic mechanism of floral organogenesis remains elusive due to their complex inflorescence architecture. Extensive molecular analyses of Arabidopsis and other plant genera and species have established the ABCDE floral organ identity model. According to this model, hierarchical combinatorial activities of A, B, C, D, and E classes of homeotic genes regulate the identity of different floral organs with partial conservation and partial diversification between eudicots and cereals. Here, we review the developmental role of A, B, C, D, and E gene classes and explore the recent advances in understanding the floral development and subsequent organ specification in major cereals with reference to model plants. Furthermore, we discuss the evolutionary relationships among known floral organ identity genes. This comparative overview of floral developmental genes and associated regulatory factors, within and between species, will provide a thorough understanding of underlying complex genetic and molecular control of flower development and floral organ identity, which can be helpful to devise innovative strategies for grain yield improvement in cereals.</P>
