The research results demonstrated that CNTs synthesized from LPG in this work were reported to be multi-walled tubes (MWCNTs: Multi-Walled Carbon Nanotubes) with physical characteristics including average internal and external diameters were of 6 nm and 17 nm, respectively. The measured specific ...

The benefit or detrimental effects of wearing contact lenses depend not only upon the substance, but also on factors including the form of the substance, characteristics and duration of the exposure, the uses of other eye protection equipment, and the hygiene of the lenses. However, there may ...

The outstanding characteristics of phenolics are good electrical properties, very rigid set, good tensile strength, excellent heat resistance, good rigidity at elevated temperature, good aging properties; also, good resistance to water, organic solvents, weak bases, and weak acids. All these characteris...
(2020) found that adsorption characteristics of phenol on AC can be better described by the Langmuir isotherm model. Supong et al. (2020), found that the best-fitted isotherm model to describe the experimental data of phenol adsorption onto AC was Langmuir indicating that the adsorption occurred...

Taste threshold valuesTaste characteristics at 3 ppm: spicy, phenolic, tobacco, musty, woody, medicinal, smoky, tarlike and slight...
LAGEL,Marie-Christine,PIZZI,Antonio,REDL,Andreas 摘要: Phenol-formaldehyde (PF) resins were prepared with a level of 10%, 20% and 30% substitution of the phenol in the resin by three types of wheat gluten protein hydrolysates having different characteristics, namely (i) an enzymatic ...
Gram staining, motility, starch hydrolysis, and gelatinase activity are common physio-chemical characteristics of bacterial strains that were carefully determined using Bergey’s manual [69]. As indicated earlier, the indole, methyl red, and hydrogen sulfide tests were also conducted [70]. All ...
Interestingly, a red shift of 6 cm−1 was observed in the peak centered at 141 cm−1, while the peaks centered at 517 and 640 cm−1 displayed a blue shift of 4–5 cm−1 (Figure 2c and Table S1 for peak at 141 cm−1) upon the excitation of 633 nm with a laser power...
