We evaluated the anxiolytic effect of γ-oryzanol (GORZ) and elucidated the molecular mechanisms involved in its inhibition of behavioral test-induced anxiety. Behavioral tests were conducted on day 13, and mice were subjected to 30 min of acute restraint stress treatment (ARST) before sacrifice...

The effect of oryzanol (well known hypolipidemic component in rice bran oil) and its chemical constituents- ferulic acid (FA) and phytosterols on hypolipidemia were investigated. Methods and Results: Docking (in silico) studies showed that FA had a better binding ability with lipase while sterol...

Natural antioxidants are a complex system of molecules that interact to scavenge free radicals and often exist as minor compounds that are important for the nutritional benefits and functions of plant oils. In this study, the scavenging activity of α-tocopherol in the presence of γ-oryzanol an...

In this work, we established multiferroic and magnetoelectric (ME) coupling characteristics in ferroelectric potassium sodium niobate K0.5Na0.5NbO3 (KNN) ceramics by substitution of dual transition metal (TM) ions such as Fe, Co. Powder X-ray diffraction (PXRD) patterns of all the compositions s...

This study was designed to better understand the microstructural and phase evolution of lead-free sodium potassium niobate based piezoceramics with a nominal composition (K0.5Na0.5)0.99Sr0.005NbO3 (KNNSr) during pressure-less spark plasma sintering followed by post-annealing in oxygen. The as-si...

Polyacrylonitrile (PAN) matrix composites dispersed with potassium sodium niobate (KNN) with volume fraction of 0–30% were prepared by ball milling followed by hot pressing. Density of composites followed the rule of mixture. Good dispersion of KNN particles in PAN matrix was confirmed using SE...

Sodium niobate thin films doped with manganese (NN), and NN films modified with 5 or 10 mol % calcium zirconate (CZ) on platinized silicon substrates were prepared by chemical solution deposition. The 250-nm-thick films crystallize in a perovskite phase with fine, equiaxed grains. The NN films e...

Although tremendous achievements have been made in enhancing recoverable energy storage density (Wrec) of lead-free dielectric ceramics for electrical energy storage applications in recent years, these ceramics with high Wrec still have two disadvantages: complex chemical composition and difficu...

Thermodynamic studies of a polycrystalline sodium niobate (NaNbO3) under equilibrium conditions by the method of Knudsen effusion mass spectrometry (KEMS) were conducted in the temperature range 1250–1485 K. The vaporization of pure Na2O(c) was investigated at temperatures of 900–1165 K. Therm...

The implant infection is one of the most serious postsurgical complications of medical device implantation. Therefore, the development of biocompatible materials with improved antibacterial properties is of great importance. It might be a new insight to apply the intrinsic electrical properties ...

Niobium oxide is known for its biocompatibility; however it lacks on bioactivity. Sodium is one of the essential elements required for the formation and maintenance of bone. In this present study, we focus on improving the bioactivity of niobium oxide by incorporating sodium ions and obtaining n...

Dense and stoichiometric NaNbO3 ceramics were difficult to be prepared by conventional sintering methods because Na2O easily volatilized at elevated temperature. In this work, the volatility of Na2O was suppressed by applying an electrical field assisted sintering method. Flash sintering was pre...

The direct formation of organomanganese bromides can be accomplished under mild conditions from the direct oxidative addition of Rieke manganese to alkyl and thienyl bromides.

The article presents the results of the synthesis and research of a new biodegradable hybrid nanosized polymer-inorganic system possessing the double nature of heavy metal ions extraction from solutions. Firstly, the sorption of metal ions takes place by the ion-exchange properties of porous man...

Suzuki cross-coupling reactions between aryl bromides and phenylboronic acids were studied over a hydroxyapatite-supported Mn catalyst (MnHAP) for the first time. An increased yield was obtained over the fluoride ion-exchanged hydroxyapatite-supported Mn catalyst (MnFAP). Under optimized conditi...

Organic–inorganic metal halide hybrids, which consist of metal halide anions and organic cations, have been widely applied in the sensor design. Instead of general lead (high toxicity) and copper (I) (weak stability) halide hybrids, the low toxic and highly luminescent manganese (II) halide hyb...

The present work demonstrates the morphology dependent synthesis of manganese oxide using simple hydrothermal method just by adjusting the reaction temperature. The structural and morphological studies confirm the formation of manganese oxide with different phases and anisotropic structures of m...

In this work, manganese oxide nanoparticles were radiolytically synthesized in the presence or absence of diethylaminoethyl-dextran hydrochloride (DEAE-dextran). Deoxygenated potassium permanganate (KMnO4) alkaline aqueous suspensions were used as a precursor. The dose rate was ~32 kGy h−1 and t...

CTAB templated Ce0.8Zr0.2O2 (CZ), MnOx-Ce0.8Zr0.2O2 (Mn-CZ), CeO2 and MnOx oxide catalysts were prepared by precipitation and tested in CO oxidation.
