Hydrogen production could be enhanced by increasing the potassium hydroxide (KOH) concentration, but higher KOH concentrations result in corrosion rates. Therefore, a deep investigation of electrochemical behavior stainless steel (SS 316L) solution is needed. This study investigates influence on behavior, surface morphology, structure, and sample phases SS 316L. The investigations were conducte...

The aim of this work was to analyze physicochemical characteristics and fatty acid profile of seed oil of Lavandula bipinnata. The total lipid content of L. bipinnata seed was 27.2%. The oil was liquid at room temperature, with a specific gravity and refractive index of 0.971 and 1.480 respectively. The acid value (5.764 mg NaOH/g), saponification number (188.75 mg KOH/g), ester value (182.98 m...

A nanometric Mg(OH)2 and MgO particles with high purity were successfully synthesized from Algerian dolomite via a leaching-precipitation-calcination process. The effect of leaching parameters, such as H2SO4 acid concentration (C), temperature (T), time (t), solid/liquid ratio (S/L), precipitation parameters: type precipitating base (KOH, NaOH, NH4OH), OH-/Mg2+ ratio, on the obtained product pr...

Prenylated 1,3-dihydroxyxanthone has been successfully synthesized using Prenyl bromide and KOH. Characterization of the compound Infra Red (IR) Nuclear Magnetic Resonance (1H-NMR) showed that monosubstituted c-prenylation was occurred at carbon number 2 to form 1,3-dihydroxy-2-prenylxanthone. The synthesis result a yellow-brown paste with yield 43.09%. This prenylated had moderate antibacteria...

Still there is no scientific report about the proximate analysis of seeds and characteristics of oil produced from brebra seed. Objective of this study was to determine proximate and antinutritional characteristics of seeds as well as the physicochemical characteristics of brebra seed oil. Crude oil, protein, fiber, ash, moisture and carbohydrate content of brebra were 48.5 ± 0.99%, 29.7 ± 0.23...

Themortality andmorbidity of chronic obstructive pulmonary disease are high. However, no radical therapy has been developed to date. The purpose of this study was to evaluate whether fetal mouse lung tissue can grow and differentiate in the emphysematous lung. Fetal lung tissue from green fluorescent protein C57BL/6 mice at 16 days’ gestation was used as donor material. Twelve-month-old pallid ...

Abstract The effect of aqueous electrolyte to the supercapacitor electrode performance made from Sugar palm ( Arenga pinnata ) fronds waste has been successfully analyzed. preparation activated carbon was used a combination chemical and physical activation methods. conducted using potassium hydroxide with 0.5 M concentration CO 2 gas. electrochemical sugar (SPFs) tested cyclic voltammetry metho...

The aim of this research is to reduce emissions by capturing carbon dioxide in a solution using an absorption method. capacity, rate, removal efficiency, and overall mass transfer coefficient MEA (Monoethanolamin) alkaline solvents (NaOH, KOH, Mg(OH)2) were investigated bubble column gas reactor with counter current flow. effects operational parameters such as solvent concentration (0.01, 0.05,...

A pyrolysis product derived from SASOL-Lurgi gasifier pitch was activated using different proportions of KOH. The increase of the amount of KOH used for activation caused the activation degree of the carbons to increase very significantly. The activated carbons obtained using lower amounts of KOH were mainly microporous, while the amount of mesopores developed in the samples progressively incre...

MSS. Intended for publication and books, etc., intended for review should be senit to Professer J. McKeen Cattell, Garrison. on-Hudson. N. Y. LIEBIG'S LAW OF THE MINIMUM IN RELATION TO GENERAL BIOLOGICAL PROBLEMS' TmE Law of the Minimum has never been accurately defined, although the idea that it involves is relatively simple. Professor B. E. Livingston says in a recent paper2 that "this prilnc...
