Internationally exploited lubricants are derived from coal and petroleum. Due to their high consumption and effects of their long-term pollution on the environment, it is imperative to use renewable and cheap feedstock for the synthesis of bio-based lubricants. This study presents the synthesis and optimization process of Ethylene Glycol (EG) based bio-lubricant from palm kernel oil. Palm Kerne...

Abstract In recent times, nano zerovalent iron (nZVI) particles have attracted significant attention from researchers for their effectiveness in removing phosphates, a hazardous contaminant found groundwater and surface water. nZVI possesses some excellent characteristics such as high reactivity, area, effective surface-to-volume ratio. this study, was characterized by X-ray diffraction, Brunau...

Instrumentation is described that has been constructed at the National Institute of Standards and Technology (NIST) for the measurement of regular re ̄ectance and transmittance over the 2±25 mm wavelength region. This includes both specialized accessories used with Fourier-transform infrared (FT-IR) spectrometers and laser-based systems for high optical density transmittance measurements. The FT...

?-Dicalcium silicate (?-C2S) is known for its strong carbonation reactivity by which it can capture atmospheric carbon dioxide (CO2), thus, be used in construction industries. This paper aims to study the effects of ?-C2S on properties ground granulated blast-furnace slag (GGBFS) containing cement mortar and paste natural accelerated curing. The compressive strength 5% (G5) added GGBFS higher c...

The application of single-pass attenuated total reflection Fourier transform infrared (ATR-FT-IR) microscopy was investigated for secondary structure analysis of 15 representative proteins in H2O solution. This is the first reported application of single-pass ATR-FT-IR for protein analysis; thus, the method was validated using transmission FT-IR and multipass ATR-FT-IR as referee methods. The s...

Biosurfactants are surface-active compounds produced by a wide variety of diverse microorganisms. The structural diversity biosurfactants depends on microorganisms and growth conditions (such as substrate pH). unique structure provides properties for specific applications. Biosurfactant production still needs to be explored using producing the biosurfactant structures. Production characterizati...

In this report, we successfully fabricated the temperature-responsive porous gel film by templating colloidal crystal (CC) of silica microparticles embedded in a hydrogel matrix poly(N-isopropylacrylamide) (NIPA). As elevating temperature from 25 ℃, showed color changes Bragg reflection red to blue, arising geometric decrease lattice spacing pores caused shrinkage NIPA upon heating process. Suc...

Biochemical analyses of substances rely upon the ability of techniques to identify qualitatively and quantitatively the components present and are based on physicochemical characteristics as well as chemical nature of substances being detected. While chemical analyses usually depend on reactions of a given substance and can be destructive, spectral studies are usually non-destructive and deal w...

THE EFFECT OF CALCINATION TEMPERATURE TO COMPOSITECHARACTERISTICS TiO2SiO2 NANOPARTICLE. Self-cleaning material is a that utilizes the photocatalytic property to degrade organic and inorganic compounds with help of UV light. One materials have good TiO2, causes TiO2 be amphiphilic: becomes hydrophilic when there light hydrophobic no The can improved addition buffer such as SiO2. nanoparticle wa...

In this study, the SDS/[email protected] composite as a novel adsorbent has been prepared via facile synergistic effect of cationic surfactant (CTAB) and anionic (SDS) for modification montmorillonite, it was utilized to remove malachite green (MG) from aqueous solutions. The structure morphology were characterized by X-ray diffraction (XRD), Fourier Transform Infra-Red (FT-IR) spectroscopy, Sc...
