Carbon Tetrafluoride, Oxygen, and Air RF Plasma Modified Low-Density Polyethylene and Polydimethylsiloxane
Polat, Osman; Bhethanabotla, Venkat R.; Ayyala, Ramesh S.; Şahiner, Nurettin (Springer, 2023)Low-density polyethylene (LDPE) and polydimethylsiloxane (silicone or PDMS) were exposed to low-pressure air, oxygen (O2), and carbon tetrafluoride (CF4) plasma to modify their surfaces. Plasma power and irradiation time ... -
Degradable poly(catechin) nanoparticles as a versatile therapeutic agent
Suner, Selin S.; Sahiner, Mehtap; Mohapatra, Subhra; Ayyala, Ramesh S.; Bhethanabotla, Venkat R.; Sahiner, Nurettin (Taylor and Francis Ltd., 2021)Poly(catechin) (p(CAT)) nanoparticles (NPs), 173 +/- 4 nm was prepared as a therapeutic agent with hydrolytic degradability affording sustainable CAT release over 20 d at carcinogenic conditions, pH 5.5 and 37.5 degrees ... -
Low-pressure plasma treated polycarbonate and polymethyl methacrylate (PMMA) sheets with different surface patterns to change their surface properties
Gizer, S. Görkem; Bhethanabotla, Venkat R.; Ayyala, Ramesh S.; Şahiner, Nurettin (Elsevier B.V., 2023)Low-pressure plasmas of carbon tetrafluoride (CF4), oxygen (O2), and air were used to treat the surfaces of polycarbonate (PC) and polymethyl methacrylate (PMMA) to achieve a variety of surface attributes, such as ... -
Versatile Fluorescent Carbon Dots from Citric Acid and Cysteine with Antimicrobial, Anti‑biofilm, Antioxidant, and AChE Enzyme Inhibition Capabilities
Sağbaş Suner, Selin; Şahiner, Mehtap; Ayyala, Ramesh S.; Bhethanabotla, Venkat R.; Şahiner, Nurettin (Springer, 2021)Nanostructured fuorescent particles derived from natural molecules were prepared by a green synthesis technique employing a microwave method.
