Sensitive fluorometric determination of picric acid and antioxidant stabilizers in propellant compositions using amine-rich nitrogen-doped carbon quantum dots

Autor: Elif Ezgi Benli, Ömer Kaan Koç, Ayşem Üzer, Reşat Apak

Publikováno v: Talanta Open, Vol 8, Iss , Pp 100245- (2023)

Determination of both trace explosives in soil samples and antioxidant stabilizers in propellant compositions using the same quantum dots is an important challenge in analytical chemistry. For this purpose, unmodified carbon quantum dots (CQDs) were

Autor: Reşat Apak, Sema Demirci Çekiç, Ayşem Üzer, Saliha Esin Çelik, Mustafa Bener, Burcu Bekdeşer, Ziya Can, Şener Sağlam, Ayşe Nur Önem, Erol Erçağ

Publikováno v: Sensors, Vol 18, Iss 1, p 186 (2018)

Since an unbalanced excess of reactive oxygen/nitrogen species (ROS/RNS) causes various diseases, determination of antioxidants that can counter oxidative stress is important in food and biological analyses. Optical/electrochemical nanosensors have a

Spectrophotometric Fluoride Determination Using St. John’s Wort Extract as a Green Chromogenic Complexant for Al(III)

Autor: Batuhan Yardımcı, Ayşem Üzer, Reşat Apak

Publikováno v: ACS Omega. 7:45432-45442

In this study, we applied an innovative approach of green analytical chemistry to develop a novel and eco-friendly chromogenic agent for fluoride determination by making use of the nontoxic Al(III)-flavonoid complex in a natural extract from St. John

Direct Determination of Peroxide Explosives on Polycarbazole/Gold Nanoparticle-Modified Glassy Carbon Sensor Electrodes Imprinted for Molecular Recognition of TATP and HMTD

Autor: Şener Sağlam, Ayşem Üzer, Reşat Apak

Publikováno v: Analytical chemistry. 94(50)

Since peroxide-based explosives (PBEs) lack reactive functional groups, they cannot be determined directly by most detection methods and are often detected indirectly by converting them to H
