used as the matrix material. Two different types of reinforcement namely silicon carbide (SiC) and multi-walled carbon nanotubes (MWCNTs) were employed. SiC powders with an average particle size within the range of 20-40 μm was obtained from Sigma- Aldrich, Malaysia while the 88% purity industrial grade MWCNTs with an outer

SiC-functionalized fluorescent aptasensor for

27/06/2020· Aptamer-modified SiC quantum dots (DNA-SiC QDs) as fluorescent aptasensor are described for the determination of Proteus mirabilis. The SiC QDs were synthesized through one-pot hydrothermal method with particle sizes of about 14 nm. The amino-modified aptamers against P. mirabilis were conjugated to the surfaces of SiC QDs for bacteria recognition.

pollutants due to its high oxidation capacity, non-toxicity, low cost, and chemical stability [8–10]. However, the practical use of TiO 2 is still hindered by low light-harvesting capability, which can only harvest light in the UV region (λ < 380 nm) of the solar spectrum. The fast recoination of photogenerated hole-electron pairs further

1500 C, easily available, and of relatively low cost. The best candidates at the current time are sapphire, templates of AlN on sapphire, boron nitride, silicon carbide (SiC), or bulk AlN substrates (if they become available at reasonable cost). In this study, we used SiC and sapphire substrates. In E, the substrate temperature is normally

CAS REGISTRY and CAS Registry Nuer FAQs | CAS

What does a CAS Registry Nuer look like? A CAS Registry Nuer is a numeric identifier that can contain up to 10 digits, divided by hyphens into three parts. The right-most digit is a check digit used to verify the validity and uniqueness of the entire nuer. For example, 58-08-2 is the CAS Registry Nuer for caffeine.
