Effects of doping on the thermophysical properties of Ag and Cu doped TiO2 nanoparticles and their nanofluids
Koçak Soylu, Sezgi; Yeşil Acar, Zerin; Asiltürk, Meltem; Atmaca, İbrahim (Journal of Molecular Liquids, 2022)A widely accepted method to improve the thermal performance of nanofluids is adding more particles to the fluid, which often causes higher viscosity and sedimentation risk. Therefore, alternative methods are required to ... -
Enhancement of enzyme activity by laser-induced energy propulsion of upconverting nanoparticles under near-infrared light: A comprehensive methodology for in vitro and in vivo applications
Ateş, Burhan; Ulu, Ahmet; Asiltürk, Meltem; Noma, Samir Abbas Ali; Demirel Topel, Seda; Dik, Gamze; Özhan, Onural; Bakar, Büşra; Yıldız, Azibe; Vardı, Nigar; Parlakpınar, Hakan (Elsevier, 2024)If the appropriate immobilization method and carrier support are not selected, partial decreases in the activity of enzymes may occur after immobilization. Herein, to overcome this challenge, an excitation mechanism that ... -
Nanoakışkanlar ve güneş enerjili sıcak su sistemlerinde kullanımı
Atmaca, İbrahim; Koçak Soylu, Sezgi; Özdemir, Osman Samet; Asiltürk, Meltem (8. Güneş Enerjisi Sistemleri Sempozyumu ve Sergisi, 2019)Nanoakışkanlar en genel tanımıyla; nanometrik boyuttaki (1-100 nm) katı partiküllerin bir temel akışkan içerisinde dağıtılması ile oluşturulan akışkanlardır. Böyle bir yapı oluşturmaktaki amaç, ısıl iletkenliği temel ... -
Near-infrared inducible supports in bio-catalysts design: A useful and versatile tool in enhancement of enzyme activity
Noma, Samir Abbas Ali; Dik, Gamze; Gürses, Canpolat; Kuruçay, Ali; Demirel Topel, Seda; Ulu, Ahmet; Asiltürk, Meltem; Ateş, Burhan (2024)Immobilized enzymes have encountered two main challenges: Reduced enzyme activity compared to free enzymes and exhausted immobilized enzymes due to reusability. Herein, we suggested a promising activity enhancement strategy ... -
Thermal performance testing of a solar water heating system using core-shell structured nanofluids
Atmaca, İbrahim; Özdemir, Osman Samet; Çağlar, Ahmet; Koçak Soylu, Sezgi; Asiltürk, Meltem (Nanoscale and Microscale Thermophysical Engineering, 2022)This study investigates the impact of core-shell-based nanofluids on the thermal performance of a solar water heating system by studying the changes in the useful heat gain and collector efficiency. This work would be the ...
