“…Observed inhibition zone in the millimeter (mm) range, compared to the standard drug Amikacin is shown in Table 3 , indicating that doped crystal showed good inhibitory action against pseudomonas aeruginosa and staphylococcus aureus bacteria than pure crystal and the antibacterial activity of pure L-LMHCl crystal towards Escherichia coli is more than doped L-LMHCL crystal. Zone resisting action of crystals against pseudomonas aeruginosa is leading than HTNN crystal ( Ravathi and Karthik, 2019 ) also it have more inhibitory action on Staphylococcus aureus than Ag nanoparticles. ( Prakasha et al, 2013 ).…”

Slow evaporation method was used to grow the pure and K + ion doped L-Lysine monohydrochloride (L-LMHCL) crystals which has optical and antibiotic applications. The space group, structure and slight shifting of peaks are confirmed using single crystal XRD and the powder XRD. The FTIR analysis also shows that the K + doped L-LMHCL has a slight shifting in the spectrum which indicates the functional group of L-LMHCL and the interaction between the K + ions. The existence of K + ion in the doped crystal is assured by the presence of potassium in the EDAX spectrum. The wide optical band gap was found for pure and K + doped crystal using UV spectra and these are utilized in optoelectronic and nonlinear applications. The Kurtz Perry technique specified the NLO property of grown crystals. The dielectric property crystals was studied by varying the temperature. As a result, the highest dielectric constant is observed in doped crystal. An antibacterial activity against certain bacteria like E-coli, pseudomonas aeruginosa and staphylococcus aureus are provided by mm range for the grown crystals.

“…Therefore, this species could be a better choice to use in synthesis of antibacterial metallic NPs. Metal oxide NPs captivated much attention from biologist, chemist, and physicist by offering edge of precise size, shape, crystallinity, corrosion resistibility, and cost effectiveness (Heidari & Brown, 2015; Revathi & Karthik, 2019; Saleem et al, 2018; Sattar et al, 2019). Cadmium oxide nanoparticles (CdO NPs) are popular metal oxides for their bactericidal and fungicidal potential against various pathogens (Karthik, Dhanuskodi, Gobinath, Prabukumar, & Sivaramakrishnan, 2018a).…”

Microbial mediated synthesis of metallic nanoparticles constitutes as effective and promising approach for the development of antibacterial materials in the field of bioengineering and biomedicine. We prepared Cadmium oxide nanoaprticles (CdO NPs) utilizing Penicillium oxalicum, and cadmium acetate solution via coprecipitate method. The elemental composition and morphology of these synthesized CdO NPs were examined through X-ray diffraction (XRD), UV-Vis absorption spectroscopy, Fourier transform infrared spectroscopy (FTIR), Scanning electron microscopy (SEM), and Energy dispersive spectroscopy (EDS). Furthermore, we evaluated the bactericidal potential of prepared CdO NPs using Escherichia coli (E.coli), Staphylococcus aureus (S.aureus), Bacillus cereus (B.cereus), and Pseudomonas aeruginosa (P. aeruginosa). Dimethyl sulfoxide was used as negative control while erythromycin was used as positive control. The XRD spectrum revealed cubic crystalline nanoparticles with 22.94 nm size and UV showed absorbance peak at 297 nm with 2.5 eV band gap energy. FTIR depicted O─H and carboxylic groups along with CdO stretching vibration. EDS showed the presence of organic compounds on Cd and O over NPs surface. SEM results revealed the spherical shape of the CdO NPs. The synthesized NPs exhibited highly potent bactericidal activity against selected strains and demonstrated less optical density of 0.086 after 24 hr. Owing to the significant antibacterial activity of CdO NPs, the broad application prospects of these nanoparticles CdO NPs in extensive biomedical applications is indicated.

“…The peak at 1400 -1 corresponds to CO 3 2-of calcium vanadium, and the peak at 1650 -1 corresponds to the hydroxyl group in CFs and water [29]. The addition of CF to the cement stone only slightly affects the type of cement hydration products, as determined by XRD and FTIR analyses [30,31].…”

In this study, carbon fibers (CFs) were used as toughening materials to improve the mechanical properties of cement stone. The surfaces of the CFs were treated with concentrated nitric acid and sodium hypochlorite to increase the interfacial adhesion between the CFs and the cement. The CFs subjected to surface treatment were evaluated by scanning electron microscopy and infrared analysis to find a significant increase in the number of oxygen-containing groups on the surface. The CFs subjected to surface treatment were added to the cement matrix. The effect of the modified CFs on the mechanical properties of the cement matrix was evaluated by testing the means of mechanical properties. The maximum tensile strength, maximum compressive strength, and ultimate strain of the enhanced cement stone of the CFs treated with sodium hypochlorite increased by 68.2%, 12.0%, and 4.4%, respectively. The maximum tensile strength, maximum compressive strength, and ultimate strain of the enhanced cement stone of the CFs treated with concentrated nitric acid increased by 72.7%, 14.7%, and 4.5%, respectively. The addition of CFs to the cement stone exerted no effect on the type of cement hydration products, as determined by infrared analysis and X-ray diffraction. The toughening mechanism of the modified CFs added to the cement stone was ultimately explored, and the bridging effect, deflection effect, and pull-out effect of cracks were evaluated.
