Abstract Carbon black is a form of amorphous carbon. It is mainly used as reinforcement filler in automobile tires and other rubber products, but is also used in pigments, paint, and carbon paper. Raman spectroscopy is a very effective analytical technology to characterize carbon materials. The Raman bands associated with different carbon bonds reveal details of the structure on the molecular ...

This method is most suitable when samples are clear solutions with proteins and peptides in a narrow concentration range. Fluorescence spectroscopy Ultraviolet and fluorescence spectroscopy is limited to the determination of a few proteins containing chromophores such as aromatic, heterocyclic or conjugated ring systems. Infrared spectroscopy ...
Raman spectroscopy is a molecular characterization technique based on Raman effect. ...
Solid-state batteries (SSBs) are currently a hot research topic in the field of electrochemical energy storage. Many believe that solid-state battery technology is the successor of lithium-ion—especially in the context of electric vehicles. The technology has the potential to revolutionize energy storage in several ways. SSBs boast a high energy density, have extended lifespans and ...

Monitoring the lubrication systems of plant equipment is critical for optimizing performance and reducing machinery downtime. On-site oil analysis supports condition monitoring by providing immediate answers regarding the condition of any lubricated equipment. It ensures the proper lubrication of equipment and it provides early detection of wear and helps with contamination ...
Fourier Transform Infrared (FTIR) - spectroscopy is used typically in testing laboratories for understanding materials and products. Fourier Transform Infrared (FTIR) - spectroscopy is used typically in testing laboratories for understanding materials and products, identifying chemical compounds in solids, liquids and gases, ...
Thermogravimetric analysis (TG) and Fourier transform infrared spectroscopy (FTIR) tests demonstrated that the surface was successfully modified by sodium citrate. ...
X-ray diffraction, scanning electron microscopy (SEM), UV–vis diffuse reflectance spectroscopy, X-ray photoelectron spectroscopy, SEM combined with X-ray energy dispersive spectroscopy, and N2 adsorption–desorption tests were employed to characterize samples' crystalline phase, chemical composition, morphology and surface ...
Infrared Spectroscopy: Infrared spectroscopy deals with exposing samples to infrared wavelengths in the electromagnetic spectrum, as well as the real-time measurement of “vibrations of inter atomic bonds at different ...
Characteristics of the adsorbent were also studied using scanning electron microscopy and Fourier transform infrared spectroscopy (FTIR). It was revealed from kinetic tests that removal efficiency of MB was 88.5% under the optimum conditions of pH 8, initial MB concentration of 50 mg/L, contact time of 60 min, and adsorbent dose of 0.3 g/L. ...
This study aimed to investigate whether Fourier‐transform infrared (FTIR) spectroscopy could enhance the duckweed (Lemna minor L.) toxicity test. Four chemicals (Cu, Cd, atrazine, and acetochlor) and four metals‐containing industrial wastewater samples were tested. After exposure of duckweed to the chemicals, standard toxicity endpoints (frond ...
However, the accumulation of oxidation by-products and acidic contaminants in an oil over time will always lead to an increase in TAN. This test is most meaningful in industrial machinery applications although sometimes it is recommended in engine applications along with Total Base Number (TBN). ...
First, experiments were conducted varying pH from 1 to 4, and showed that a combined effect of biosorption and reduction is involved in the Cr(VI) removal. Then, X-ray photoelectron spectroscopy and desorption tests were employed to verify the oxidation state of the chromium bound to OS and to elucidate the removal mechanism of Cr(VI) by this material. The goal ...
Therefore, the film formation of oleyldiamine, a commonly used FFA, on carbon steel has been studied with electrochemical impedance spectroscopy (EIS) in defined test water, containing 200 mg L-1 of NaCl, with and without the presence of different AAs. ...
