The influence of KOH addition and air pretreatment on co-pyrolysis (600 °C) of a mixture of bio-oil and biomass (aspen wood) was investigated with the goal of increasing biochar yield. The bio-oil was produced as a byproduct of the pyrolysis of biomass and recycled in subsequent runs. Co-pyrolysis of the biomass with the recycled bio-oil resulted in a 16% mass increase in produced biochar. The ...

Blood stasis is a very important pathophysiological concept not only in Kampo but also in traditional Chinese medicine. Blood stasis indicates severe disease. Fuku shin (the abdominal exam) and Zetsu shin (the tongue exam) are the most important approaches of the 4 diagnostic procedures in Kampo. Tenderness of the lower abdominal region ( Sho fuku koh man) and distended sublingual veins have be...

Alkaline rechargeable batteries (ARBs) are predicted to be an attractive solution for large-scale electrochemical energy storage applications. However, their advancement is greatly hindered by the lack of high-performance and sustainable anode that can stably operate in less-corroding, low electrolyte concentration. Herein, we report first example polymer ARB able concentrate (1м potassium hydr...

While potassium hydroxide (KOH) activation has been used to create pores in carbon nanotubes (CNTs) for improved energy-storage performance, the KOH activation mechanism of CNTs has been rarely investigated. In this work, the reaction between single-walled CNTs (SWCNTs) and KOH is studied in situ by thermogravimetric analysis coupled to infrared (IR) spectroscopy and gas chromatography/mass spe...

Methods. Skin scrapings were taken from outpatients with superficial dermatomycoses and cultured in Sabouraud dextrose agar with cycloheximide. They were then evaluated under a microscope using both the KOH wet mount technique and the new contrast stain. Two investigators read the slides together but were blinded to all other test results. The new contrast stain contains 1% Chicago sky blue 6B ...

Porous sulphur-doped carbons have been prepared by using polythiophene (PTh) as carbon precursor and KOH as activating agent. The activation process was carried out under several operating conditions, i. e. a KOH/PTh weight ratio of 2 or 4, and reaction temperatures in the 600-850 oC range. The porous carbons thus obtained exhibit very large apparent surface areas and high pore volumes of up to...

Plant lignin is one of the major wall components that greatly contribute to biomass recalcitrance for biofuel production. In this study, total 79 representative Miscanthus germplasms were determined with wide biomass digestibility and diverse monolignol composition. Integrative analyses indicated that three major monolignols (S, G, H) and S/G ratio could account for lignin negative influence on...

The effects of seven commercially available alkaline cleaners used in the food processing industry, 0.025 M NaOH, and 0.025 M KOH on viability of wild-type (EDL 933) and rpoS-deficient (FRIK 816-3) strains of Escherichia coli O157:H7 in logarithmic and stationary phases of growth were determined. Cells were treated at 4 or 23 degrees C for 2, 10, or 30 min. Cleaners 2, 4, 6, and 7, which contai...

The agar diffusion assay was used to examine the effect of pH on the ability of alkaline salts of 3 fatty acids (FA) to inhibit growth of bacteria associated with poultry processing. FA solutions were prepared by dissolving 0.5 M concentrations of caprylic, capric, or lauric acid in separate aliquots of 1.0 M potassium hydroxide (KOH). Citric acid was added to the FA-KOH mixtures to reduce the ...

Currently the waste generated from public consumption in Indonesia is very high. One such used palm oil households and food companies. Utilization of this research by recycling into surfactants which will be Enhanced Oil Recovery (EOR) process. The surfactant concentrations were 1.3%, 1.5%, 2%, 2.2% 2.5%. began with refining cooking banana peels for 24 hours. In order to make surfactants, mixed...
