A novel greener method to impregnate silver nanoparticles (AgNPs) into microcrystalline cellulose (MCC) by curry leaf (Murraya koenigii) extract is presented. The active reduction of silver ions by curry leaf extract was explored for the in situ impregnation AgNPs into MCC. Transmission electron microscopy (TEM) analysis of MCC coated with AgNPs showed the formation of silver particle sizes in ...

In this work we report the experimental assessment of the performance of a new catalytic hollow fiber reactor with supported Pd catalyst for nitrite removal from polluted waters. The reactor configuration facilitates working at low flowrate and hydrogen concentrations in order to improve the selectivity of the reduction reaction towards nitrogen, thus, inhibiting the formation of ammonia. Pd ca...

Study of dendritic morphology through Golgi impregnation techniques has significantly furthered our understanding of neuronal development, maturation, and senescence. It has also provided insight into the pathogenesis of a wide spectrum of disease processes ranging from brain malformations to degenerative disorders. Golgi impregnation remains virtually the only method for demonstrating dendriti...

All metallic impregnation methods depend on the presence of reducing groups in tissues. By testing the effect of various reduction indicators on sections of nervous tissue it was found that some reduction systems do not have a high enough oxidizing potential to serve for the visualization of either axons or myelin. Others can visualize myelin sheaths. The systems having the highest potential vi...

Division of Biomedical Sciences (Anatomy) St George's, University of London London, UK ABSTRACT: The standard method for plastination with Biodur TM S10/S3 involves lowtemperature dehydration in a volatile intermediary solvent followed by forced impregnation under vacuum at -15°C. However, some institutions have been reluctant to install low-temperature impregnation equipment because of health ...

BACKGROUND We assessed the feasibility and results of active case detection (ACD) of visceral leishmaniasis (VL), post kala-azar dermal leishmaniasis (PKDL) and other febrile diseases as well as of bednet impregnation for vector control. METHODS Fever camps were organized and analyzed in twelve VL endemic villages in Bangladesh, India, and Nepal. VL, PKDL, tuberculosis, malaria and leprosy we...

Background and Objective: Although diabetes mellitus is known to be one of the risk factors for dementia but neuropathic changes in the brain of diabetic patients have not been completely revealed. Therefore, this research study was done to evaluate structural changes in pyramidal neurons of hippocampal CA1 area of male diabetic rats using Golgi-impregnation method. Materials and Methods: Male ...

Introduction Nitrogen oxides (NOx) cause the photochemical smog, acid rain, ozone depletion and greenhouse effect. Therefore, a great deal of studies has been performed to reduce NOx by using various catalytic systems such as selective catalytic reduction (SCR) or NOx storagereduction catalyst. Recently, N2O, whose greenhouse effect is 310 times larger than CO2, has been issued due to the new r...

A series of monometallic Ru, Pd, and bimetallic Ru–Pd catalysts loaded on CeO2 support have been prepared via mechanochemical conventional incipient wetness impregnation methods used in the partial oxidation methane (POM) to obtain synthesis gas (H2 CO). The influence preparation method, order addition metals, Ru:Pd metal ratio, milling energy time for samples by evaluated between 300 600 °C. r...
