“…Because the higher the concentration, the more enzymes are inhibited and quicker death of the organism. [43] Another possible mechanism for the antimicrobial action of the vic-dioxime metal complexes is that the reactivity of the current M-chelates over their uncoordinated ligand could be assigned to their central M 2 + ion with a positive charge, which could strongly develop their antibacterial potential with the chelation theory effect. [44,45] Table 2.…”

In this work, novel vic-dioxime ligand (LH 2 ) containing bound to the N 4 -oxime core moiety and its complexes with Cu(II), Ni(II), Ti(IV), VO(IV), and Zn(II) salts have been studied. The structure of the ligand and its complexes were successfully synthesized and characterized using NMR ( 1 H and 13 C), LC/MS/MS spectrometer, FT-IR and UV/ VIS spectroscopy, melting point, and magnetic susceptibility measurements. Vic-dioxime ligand (LH 2 ) (1) and its metal complexes ([Cu(LH) 5), and [Zn(LH) 2 ] (6), respectively) were tested for them in-vitro antibacterial and antioxidant activities. According to the metal chelating results of the study, it was determined that compounds (1), ( 2), ( 3), and ( 6) showed very good activity, and especially compound (2), had a stronger metal chelating capacity due to ligand dissociation from the synthesized metal complexes, which then would chelate Fe(II) in the experimental setting. When microorganisms were evaluated in terms of the % viability effect, it was observed that all compounds had activity against C. Albicans and S. Cerevisiae at rates similar to antibiotics.

“…Despite its potential, progress in this method has been limited. This is primarily due to the high cost and scarcity of volatile and stable organometallic compounds. − Notably, cold plasma deposition allows for the precise deposition of nanometer-scale metal–organic compounds on organic biocompatible substrates.…”

Although metal−organic thin films are required for many biorelated applications, traditional deposition methods have proven challenging in preparing these composite materials. Here, a Co-organic composite thin film was prepared by plasma-enhanced atomic layer deposition (PEALD) with cobaltocene (Co(Cp) 2 ) on polydimethylsiloxane (PDMS), using two very high frequency (VHF) NH 3 plasmas (60 and 100 MHz), for use as a tissue culture scaffold. VHF PEALD was employed to reduce the temperature and control the thickness and composition. In the result of the VHF PEALD process, the Young's modulus of the Co-organic composite thin film ranged from 82.0 ± 28.6 to 166.0 ± 15.2 MPa, which is similar to the Young's modulus of soft tissues. In addition, the deposited Co ion on the Co-organic composite thin film was released into the cell culture media under a nontoxic level for the biological environment. The proliferation of both L929, the mouse fibroblast cell line, and C2C12, the mouse myoblast cell line, increased to 164.9 ± 23.4% during 7 days of incubation. Here, this novel bioactive Co-organic composite thin film on an elastic PDMS substrate enhanced the proliferation of L929 and C2C12 cell lines, thereby expanding the application range of VHF PEALD in biological fields.

“…B 2 O 3 can be used as additives to improve textural and acid-base properties of common metal oxides [3]. B 2 O 3 can also be utilized in the industry as a raw component for the processing of commercial alloys and it can be used as a precursor for the synthesis of common compounds like TiB 2 and MoB 2 [4]. In addition, the capability of B 2 O 3 for thermochemical energy storage has been studied.…”

In this study, boron oxide (B 2 O 3 ) powder has been synthesized by the pyrolysis of polyvinyl borate precursor in air. For this purpose, polyvinyl borate precursor was synthesized through the condensation reaction of polyvinyl alcohol and boric acid, and then the polymeric precursor was pyrolyzed at 500°C. The as-prepared B 2 O 3 particles were doped with iron (Fe) ions using the wet impregnation method. The photocatalytic activity of both undoped B 2 O 3 and iron doped B 2 O 3 (Fe-B 2 O 3 ) powders was studied by investigating the degradation of the model dye, methylene blue, under UV light irradiation. It was pointed out that iron doped B 2 O 3 powder exhibited enhanced photocatalytic activity compared to undoped one. In addition, various techniques of characterization such as FTIR, XRD, FESEM, EDX and UV-Vis spectroscopy were performed to confirm the synthesis of B 2 O 3 particles and the presence of iron ions in the crystal structure of the prepared photocatalyst. The novelty of this study was to research the photocatalytic performance of both B 2 O 3 and Fe-B 2 O 3 photocatalysts.
