In this work, we designed and studied two synthetic routes, based on modified Hummers method, to obtain graphene oxide (GO), investigated their influence the performance of polypropylene (PP)/GO nanocomposites. The routes differed in application condition oxidizing agent, potassium permanganate (KMnO4), which was added either as a powder (GO-P) or water solution (GO-S). This apparently subtle c...

Potassium permanganate has become an established fixative in electron microscopy (Luft, 1956) and has special value in the study of cell membranes. During an investigation of methods of increasing the contrast in the electron microscope of tissues embedded in epoxy resin, t a solution of potassium permanganate was used to treat the sections, using a technique similar to that of Watson (1958). P...

We report the enhanced capacitance of the Multi-Walled Carbon NanoTubes (MWCNTs) after a chemical unzipping process in concentrated sulfuric acid (H2SO4) and potassium permanganate (KMnO4). The effects of the test duration and temperature were investigated on the unzipping process of the MWCNTs to synthesize the graphene oxide nanoribbons. The SEM and TEM studies were carried out on untreated a...

This study was conducted to investigate Serratia liquefaciens infection in juvenile cultured rainbow trout (Oncorhynchus mykiss Walbaum) during June and July in 1996 about 20 days after flooding in three farms in Erzurum. Bacterial isolates were identified from each farm and tested to determine sensitivity against 18 chemotherapeutants. In addition to minimum bactericidal concentrations (MBC) o...

A conditional block to transcriptional elongation is an important mechanism for regulating c-myc gene expression. This elongation block within the first c-myc exon was defined originally in mammalian cells by nuclear run-on transcription analyses. Subsequent oocyte injection and in vitro transcription analyses suggested that sequences near the end of the first c-myc exon are sites of attenuatio...

Physical, chemical, and biological fractions of SOC pools, such as coarse particulate organic matter C (CPOM-C), permanganate oxidizable C (KMnO4-C), microbial biomass carbon (MBC), and mineralizable C (Cmin) respond to changes in management practices and provide sensitive indication of changes in the SOC dynamics than commonly reported total soil C alone. We hypothesized that tillage and N-fer...

The oxidations of organic compounds by permanganate under solvent free conditions have been studied. Thiols and primary aromatic amines undergo oxidative coupling reactions to give disulfides and diazenes, respectively, sulfides are oxidized to sulfones, primary and secondary alcohols are converted to aldehydes and ketones, 1,4-diols and cyclic ethers give lactones and arenes are oxidized to th...

Introduction The terms sewage, sludge, municipal wastewater, and others related to the collection and disposal of human and industrial wastes almost automatically “trigger” a negative reaction by the general public, due primarily to the odors that are coincidental to the transport and treatment of wastewater. I t is probably true that every sewage collection system and treatment plant has encou...

The permanganate method was applied to tissues from 35 cases of amyloidosis seen at the University Hospital. Kuala Lumpur. This method is based on the difference in affinity of various chemical types of amyloid for Congo red dye after treatment with potassium permanganate. Our findings agree with the concept that amyloid of largely immunoglobulin light chain composition (primary and myeloma amy...

ethylene affects the ripening of fruits and is naturally produced in most plant tissues. its production and accumulation during storage can cause serious damage to stored fruits such as black sweet cherries (cv: takdaneh mashhad). it affects shelf-life and can cause a marked increase in respiration rates, increasing ripening and senescence. in some commodities, accelerated aging and the initiat...
