Antibacterial application of synthesized Ce doped TiO2 and its characterization

Recently, Cd-TiO2 Nanocomposite has been synthesized by sol gel methods for the study of the antibacterial activity on Gram positive and Gram-negative bacteria by well diffusion method. This prepared Cd-TiO2 Nanocomposite have been characterized by X‐ray diffraction (XRD), Scanning electron microscopy (SEM- EDAX), Ultra Violet Spectroscopy (UV), Fourier Transform Infrared Spectroscopy (FTIR) and Surface Area Analysis (BET). The respective XRD patterns indicate crystalline nature having a rhombohedral structure. The particle size of Cd-TiO2 nanocomposite in 35nm. SEM images confirm the spherical morphology of the sample. The purity of the synthesized Cd-TiO2 Nanocomposite has been confirmed from the energy‐dispersive X‐ray (EDAX) spectra and then C, O, Ti, Cd, Pt element are present in Cd-TiO2 Nanocomposite. The weight percentage of Cd is 5.8%, Ti is 51.03%, C is 5.13% and O is 31.75% in Cd-TiO2 Nanocomposite. BET image shows that the major pore size distribution of Cd-TiO2 nanocomposites is ranged from 2.24nm. The Cd-TiO2 nanocomposite showed that the antibacterial activity when tested against the pathogens only gram-negative bacteria such as Pseodomonous. The zone of minimum inhibition concentration was measured in a range of 20mm in 25μl and 30mm in 100μl.

Tailored Synthesis of PS@Ag@TiO2 Core-shell Nanocomposite for Photocatalytic Dye Degradation_Crimson Publishers

Tailored Synthesis of PS@Ag@TiO2 Core-shell Nanocomposite for Photocatalytic Dye Degradation by Himadri Acharya* in Crimson Publishers: Peer Reviewed Material Science Journals 

Here, we describe a simple chemical method to synthesize multi component PS@Ag@TiO2 nanocomposites. The three-step synthetic approach comprises of synthesis of polystyrene (PS) particles, deposition of silver (Ag) nanostructure and coating of titanium dioxide (TiO2) nanoshells. As synthesized materials is characterised by microscopic and spectroscopic techniques. The size of the PS particles is obtained as approx. 200nm in diameter. Ag nanoparticles deposited PS particles are indicated by the surface plasmon band resonance in UV-vis study. To study the potential application, the photocatalytic activity of the PS@Ag@TiO2 nanocomposites is investigated in Methylene Blue (MB) dye degradation. Nanocomposite provides high photocatalytic degradation with a maximum efficiency of over 90% only in 30min.

Montmorillonite-silica Nanocomposite for Dye Removal from Solution | Chapter 01 | Advances in Applied Science and Technology Vol. 3

Dyes are  used  in various  industries  such as  pharmaceutical,  cosmetic, paper,  leather,  food stuff, plastics, and textile etc. The dye effluents are discharged into environment by either water or land. The discharge of these effluents into the receiving environments results in hazardous health problems as most of these dyes have carcinogenic effects on the living organisms. Congo red was removed on Montmorillonite-silica nanocomposite from solution by adsorption process. The adsorption parameters studied  were adsorbent  dose, initial  concentration  and contact  time.  The optimum  adsorption parameters were found to be 2 mg/L, 1.5 g and 40 minutes for initial concentration, adsorbent dose and  contact  time respectively  with  removal percentage  of  84.10%. Pseudo  first and  second order kinetics were used for the studies. Pseudo second order best fit the adsorption process with R²= 1 than the Pseudo first order which has R²= 0.933. Experimental data were best fitted by the Langmuir Isotherm  with  R²=0.9024  other than  the  Freundlich Isotherm,  R²=0.568.  The RL  of  0.994 of  the Langmuir  isotherm shows  the  favourability of  the  adsorption process.  The  maximum adsorption capacity by Langmuir isotherm was found to be 172. 40 mg/g. The adsorption process of Congo red was carried  out  using Montmorilonite  silica  nanocomposite.  From the  experimental  data the percentage removal of 84.10% obtained at an optimum initial concentration of 2 mg/l, an optimum adsorbent dose of 1.5 g and optimum contact time of 40 minutes. Experimental data were best fitted by the Langmuir Isotherm with R²=0.9024 other than the Freudlich Isotherm, R²=0.568. The pseudo second order kinetic with R²= 1 best fit the adsorption process other than the pseudo second order kinetics,  R²=0.933. Therefore, montmorillonite-silica nanocomposite  obtained  from montmorillonite clay and Rice husk ash can serve as a cost-effective adsorbent in the removal of Congo red dye.

Magnetic Properties of New Nanoporous Material for Data Storage, Attracts Attention

Magnetic Properties of New Nanoporous Material for Data Storage, Attracts Attention

Electronic devices which store information through magnetisation rely on magnetic switching, typically enabled by localised magnetic fields (generated via electromagnetic induction) or by spin-polarised electric currents (spin-transfer torque). However, both systems require relatively high electric currents which heat up materials, resulting in significant energy loss through heat dissipation –…
