Publication Electrochemically characterized energy storage properties of Ni foam/poly (EGDMA-Co-VPCA)/SWCNT composite electrode produced by surface polimerization method(Elsevier, 2021-05-21) Yıldırım, Hasan; Tokgöz, Seyit Rıza; Peksöz, Ahmet; Kara, Ali; Yıldırım, Hasan; TOKGÖZ, SEYİT RIZA; PEKSÖZ, AHMET; KARA, ALİ; Bursa Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Fizik Bölümü.; Bursa Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Kimya Bölümü.; 0000-0001-6552-1112; 0000-0003-4050-4222; 0000-0001-9135-1508; 0000-0003-2457-6314; AHB-9353-2022; HRA-2244-2023; IXW-9711-2023; A-8113-2016Poly (EGDMA-co-VPCA)/SWCNT composite film is successfully synthesized on Ni foam substrate by surface polymerization technique. Energy storage properties of Ni foam/poly (EGDMA-co-VPCA)/ SWCNT composite electrode are investigated via cyclic voltammetry, galvanostatic charge-discharge and electrochemical impedance spectroscopy. The as-prepared Ni foam/poly (EGDMA-co-VPCA)/ SWCNT composite electrode exhibits high specific capacitance of 100 F/g at 5 A/g, high power density of 3285.0 W/kg at 8.5 Wh/kg energy density, capacitive retention of 77.7% after 5000 charge-discharge cycles and excellent chemical stability.Publication Electrical and optical properties of photodiode structures formed by surface polymerization of P(Egdma-Vpca)-Swcnt films on n-si(Elsevier, 2019-06-20) Kirezli, B.; Gücüyener, İsmet; Kara, A.; Kaplan, H.

While electrical properties were measured at different temperatures, optical properties were measured at room temperatures. Dark and light current characteristics were investigated. Spectral photoresponse measurements of the structure were realized at room temperature. They showed that the fabricated structure exhibited rectification behavior, which makes it a good nominee for optoelectronic implementation area.Publication Ph effects on reactive orange 16 adsorption of m-poly(divinyl benzene-n-vinyl imidazol) microbeads(Yıldız Teknik Üniversitesi, 2021-03-01) Kaplan, Büşra Elif; Kara, Ali; Eren, Huseyin Aksel; Kaplan, Büşra Elif; Kara, Ali; KARA, ALİ; Eren, Huseyin Aksel; EREN, HÜSEYİN AKSEL; Bursa Uludağ Üniversitesi/Mühendislik Fakültesi/Tekstil Mühendisliği Bölümü; 0000-0003-3908-5139; AFL-4209-2022In this study, Reactive Orange 16, which is a reactive dye, was investigated by using magnetic poly (DVB-VIM) to determine the effect of pH on adsorption. For this reason, the effect of pH on adsorption has been investigated in detail in pH: 2 and pH: 12. Magnetic poly (DVB-VIM) microbeads were characterized by scanning electron microscopy (SEM), fourier-transform infrared spectroscopy (FTIR) studies and swelling studies.Publication Synthesis and characterization of polyvinylimidazole and investigation of its antipilling effect on different fabrics(E.U. Printing and Publishing House, 2021-09-30) Büyükkoru, Burcu; Kara, Ali; Büyükkoru, Burcu; KARA, ALİ; Bursa Uludağ Üniversitesi/Fen-Edebiyat Fakültesi/Kimya Bölümü.; 0000-0003-2457-6314; 0000-0002-3399-9899; CIH-1820-2022; AAG-6271-2019Pilling is one of the major concerns in textile industry. To improve pilling values of the fabrics, some methods have been reported. One of which is chemical finishing. In this study, these chemical finishing methods have been used. A key differentiator of this study is that the polymer employed as an anti-pilling agent was synthesized by the researchers of this study and does not negatively affect the hydrophilicity and brightness of fabrics. As most anti-pilling chemicals, polyvinylimidazole (PVIM) was synthesized and applied to fabrics to reduce the pilling tendency. 1.5-2 degrees improvement was observed in the pilling values ranged 4.5-5.0, which means there were no pills on the fabric surface. It has also been proven that PVIM can be used as an anti-pilling agent without negative effects on fabrics in terms of hydrophilicity, brightness and hand. The PVIM was named RUCO-PLAST EPG 18042 to be included in Rudolf-Duraner's product list.Publication Synthesis and characterization of polymer microspheres and its application for phenol adsorption(Desalination Publ, 2019-08-01) Özdemir, İnci; Kara, Ali; Tekin, Nalan; Olgun, Asim; KARA, ALİ; OLGUN, ASİM; Bursa Uludağ Üniversitesi/Fen-Sanat Fakültesi/Kimya Bölümü; 0000-0003-2457-6314; AAG-6271-2019; ABD-2316-2020This paper reports synthesis of the poly(ethylene glycol dimethacrylate-n-vinyl imidazole) ([poly(EGDMA-VIM)]) microspheres by suspension polymerization for the removal of phenol from an aqueous solution. The synthesized [poly(EGDMA-VIM)] microspheres were characterized by various analysis techniques. The [poly(EGDMA-VIM)] microspheres possessed a high specific surface area (304.4 m2 g(-1)). It was found that the pseudo-second-order kinetic and Freundlich isotherm models could well define the phenol adsorption process. The maximum capacity of the [poly(EGDMA- VIM)] microspheres was calculated to be 34.7441 mg g(-1) at 298 K and natural pH from Langmuir isotherm. The adsorption thermodynamics revealed that the adsorption of phenol was an exothermic and spontaneous process. The [poly(EGDMA-VIM)] microspheres were easily regenerated by using a 0.01 M NaOH solution, and were repeatedly used for at least 5 cycles without losing the adsorption capacity. The experimental results suggest that the [poly(EGDMA-VIM)] microspheres can be implemented as a promising adsorbent for phenol removal from wastewater.
