Tailored Rh surface facilitates, enhancement of Raman scattering in trimetallic AuPt core/Rh shell composites: Experimental and theoretical evidences

Silicate Matrix with Implanted Peptide Self-Assemblies for Smart Sensor Electrodes and Coated Glass Systems

“…The UV-vis-DRS of SiO2 and BTTPNTs@SiO2 matrix was recorded with UV-3600 Shimadzu (Japan) spectrometer in the range of 600-200 nm. The samples were prepared for the measurement by piling a small amount of barium sulphate powder and it is used as standard, subsequently, the sample was spread into thin uniform layer by using glass rod [28,30,39]. X-Ray Diffraction (XRD) was recorded on Inel Pro model X-ray diffractometer from analytical instruments operate at voltage of 40 kV and current of 30 mA with Cu KD radiation.…”

“…Nafion membrane helps loaded sol to stick on the electrode surface and works as proton exchange membrane. All solutions were passed with high purity nitrogen gas before obtaining the CV measurements [1,30].…”

“…The mixture was stirred for 30 min at room temperature to form the BTTPNTs@SiO2 matrix, which resulted in the formation of dense sol-gel matrix having BTTPNTs@SiO2. The solid was dried at 100qC for 12 h [5,30]. Finally, the sol-gel product was ground well and used for further studies.…”

“…F(R) values are calculated from recorded reflectance (R) by using Kubelka-Munk algorithm {F(R) = (1-R) 2 /2R}. Where, F(R) is Kubelka-Munk algorithm and R is diffuse reflection of powder planes [30,34]. Direct band gap (Eg) of BTTPNTs and BTTPNTs@SiO2 matrix is obtained from Tauc plot which is given in Figs.…”

“…The results are focused on the shielding of biomolecules to protect them and to create a single entity [22]. Recently, new class of solgel derived materials have been introduced with the mentioned rationalization on making porous matrix, which is compatible with the biomolecules [25][26][27][28][29][30][31][32][33][34]. Silicate matrix serve as reservoir for water, and it increases the ability to maintain the biological activity of enzymes, anti-bodies, and body fluid cells etc., [35][36][37][38][39].…”
