We synthesized mesoporous SiO2 nanomatrix using rice husks as a precursor through facile thermal combustion process. XRD, FTIR, EDX, and TEM analyses were used to validate the produced nanomatrix. Electrochemical measurements determine specific capacitance of nanomatrix, results showed that capacitances are 216, 204, 182, 163, 152, 142, 135, 133, 124.4, 124 F/g at current densities 0.5, 1, 2, 4...

Rice bran is the cuticle existing between the rice and husk of the paddy and consists of embryo and endosperm of the seeds of Oryza sativa, family Graminae. It is obtained as a byproduct in rice mill during polishing of rice obtained after dehusking of paddy. Rice bran contains about 15% of fixed oil and is obtained by solvent extraction method. It contains oleic acid, linolenic acid as unsatur...

The aim of this study was to prepare β-wollastonite using a green synthesis method (autoclaving technique) without organic solvents and to study its bioactivity. To prepare β-wollastonite, the precursor ratio of CaO:SiO₂ was set at 55:45. This mixture was autoclaved for 8 h and later sintered at 950 °C for 2 h. The chemical composition of the precursors was studied using X-ray fluorescence (XRF...

BACKGROUND Plantago ovata husk therapy could be used in patients with Parkinson disease to reduce the symptoms of gastrointestinal disorders, but it is important to know whether this compound modifies levodopa pharmacokinetics. The maintenance of constant plasma concentrations of levodopa abolishes the clinical fluctuations in parkinsonian patients. The aim of this randomised clinical trial was...

---------------------------------------------------------------------***--------------------------------------------------------------------Abstract Over the past few decades Road infrastructure in India is developing at a quick pace. A decent pavement is required for the safe, comfortable and prudent development of traffic. The thickness of road relies on geotechnical properties of subgrade so...

A study was conducted to investigate the bioaccumulation of arsenic by twelve different high yielding, hybrid and local rice varieties, cultivated in the Nadia district, West Bengal (India). The results showed that rice plant accumulated arsenic from irrigation water but, the magnitude of accumulation was found to vary with the rice varieties. Some of the examined rice varieties (like IET 4094,...

A mild, efficient and fast method for the oxidation of alcohols and trimethylsilyl, tetrahydropyranyl and methoxymethyl ethers to their corresponding carbonyl compounds using CrO3 in the presence of rice husk ash (RHA) is reported. All reactions were performed at room temperature in high to excellent yields. A new, efficient and green catalyst, heterogeneous reaction conditions, easy work-up of...

a novel rice-husk-silica supported n-propyl bipyridinium chloride (rhprbpcl) has been prepared. due to the basicity of rhprbpcl, it was decided to evaluate its catalytic activity in the one-pot preparation of tetrahydrobenzo[b]pyran, dihydropyrano[3,2-c]chromene and dihydropyrano[4,3-b]pyran derivatives. the catalyst was characterized by ft-ir, sem and tga analyses. this methodology offers seve...
