“…While the ash yield of nanocellulose was 1% at 750 °C, this value increased to approximately 25% in nanocomposite material with 1% CWR. Ash yield prevents the flame from reaching the inner parts of the material in combustion events and thus contributes to the improvement of the non-flammability properties of the material (Birtane et al 2021). When all the results were examined, the highest thermal stability was observed in the NCCWR-100 sample with 1% CWR additive.…”

Recycling is one of the most popular research topics today. In this study, in addition to the evaluation of waste tires, which are frequently encountered in the industry and difficult to dispose of, a green biomaterial, nanocellulose-based new generation nanocomposite was produced and characterized for the first time. Carbonized waste rubber, obtained by pyrolysis of tire wastes, was reinforced with nanocellulose at levels of 0.10%, 0.25%, 0.5%, and 1% by weight. The prepared nanocellulose-based nanocomposites were investigated by X-ray diffraction (XRD), morphological properties by scanning electron microscopy (SEM), thermal properties by thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), and dynamic mechanical thermal (DMTA). In addition, the percentage of gel contents of the produced nanocomposites were determined. Thermal analyses revealed that the sample containing 1% carbonized waste rubber showed the highest thermal stability and at 750 °C the ash yield increased up to 25% compared to nanocellulose. The fabricated nanocomposites had about 10 times higher storage modulus compared to pure NC. All results show that the green nanocellulose-based nanocomposites can be used for future applications in industry.

“…In the presented study, pyrazole based 1-(naphthalen-2-yl)-2-(1H-pyrazol-1-yl) ethanone (MPPY) was synthesized and characterized as a new photoinitiator in the light of α-amino acetonaphthone derivatives [23][24][25][26]. In addition, photochemical and antibacterial properties of MPPY were investigated for biomedical applications [27][28][29].…”

1-(naphthalen-2-yl)-2-(1H-pyrazol-1-yl) ethanone (MPPY) was synthesized. The structure was characterized by spectral analysis (1H-NMR, FTIR). The molar absorptivity of MPPY is high enough, similarly to acetonaphthone derivatives, to be used as an efficient type I photoinitiator. The influence of MPPY concentration and the addition of the co-initiator N-methyldiethanolamine (MDEA) on methyl methacrylate (MMA) polymerization were also investigated. Additionally, MPPY showed good antibacterialactivity against Escherichia coli and Staphylococcus aureus (diffusion method).

In our study, a selective and sensitive determination method was developed for Cu(II) ions by spectrofluorimetry. For this purpose, a polymeric membrane was prepared to determine Cu(II) ions by curing crosslinkers, functional monomers, and photoinitiators under UV light. The membrane was characterized, and the optimum conditions for determining Cu(II) ions were systematically investigated. The detection was performed at pH 5.0 in as little as 20 seconds at excitation and emission wavelengths of 376 nm and 455 nm, respectively. The linear range was 7.86.10-9-1.57.10-7 mol/L, and the method's detection limit was 2.24.10-9 mol/L. In addition, the sensor's repeatability, stability, and life were examined, and recovery studies were conducted. As a result, the developed method has been successfully applied to wastewater samples as a real sample. In addition, determining Cu(II) ions at low concentrations can be done quickly, reliably, and with high selectivity and sensitivity.
