Hydropower's Role in Enhancing Energy Justice: Preliminary Insights from the EU and Turkey

Telli, Azime | Kırışık, Avnihan

This study examines recent energy transition policies and the conceptual framework of energy justice, emphasizing the role of hydropower, in ensuring the equitable distribution of energy services and burdens. The analysis focuses on the EU’s energy mix, highlighting the capacity of hydropower and its impact on energy justice, and examines the relationship between migration and energy poverty in countries such as Poland, the Czech Republic and Turkey. In addition to their role as a source of renewable energy, hydropower offer a range of other benefits, including irrigation, flood control, water supply and fisheries. Despite these benefits, the construction of dams can also give rise to several social impacts, including environmental degradation, displacement of local communities and disrupt...

Micro-shear bond strength of resin cements to Er, Cr: YSGG laser and/or acid etched enamel

Cengiz Yanardag, Esra

The purpose of this study was to evaluate the effect of Er,Cr:YSGG laser irradiation and/ or acid etching on the micro-shear bond strength (µSBS) of two different dual-cured resin cements to human enamel. 24 intact, extracted molars were sectioned longitudinally and randomly divided into three subgroups according to three surface pretreatment methods: (1) Er,Cr:YSGG laser (Waterlase MD, Biolase) irradiation was used with a power setting of 2 W (55% water and 65% air), and a repetition rate of 20 Hz for 10s; (2) 37% phosphoric acid application for 20s; (3) Re-etching with phosphoric acid for 20s after the Er,Cr:YSGG laser irradiation as in group1. 12 enamel discs for each of the resin cements (Panavia F2.0 and Variolink N) were prepared and three cylinders of resin cements were bon...

These devices are paired with compact, user-friendly instrumentation powered by microprocessors. Pollution control will surely benefit greatly from ‘smart’ sensors and other advancements in selective and stable identification elements, such as distant electrodes, molecular devices, multi-parameter sensor arrays, micromachining, and nan...

Designing a selective electrochemical nanosensor based on molecularly imprinted polymer for detection of pirfenidone

In this study, an electrochemical determination of pirfenidone(PIR), an antifibrotic drug, was developed for the first time with a bare glassy carbon electrode(GCE) and a molecularly imprinted polymer(MIP)-based nanosensor. A molecularly imprinted polymer(MIP) incorporating o-phenylenediamine(o-PD), chitosan(CHIT), ionic liquid(IL), and diamond nanoparticles(DiaNPs) was utilized to modify a glassy carbon electrode(GCE), developing a stable and selective electrochemical nanosensor(MIP/CHIT@IL@DiaNPs/GCE) for PIR detection. The designed MIP/CHIT@IL@DiaNPs/GCE was characterized by electrochemical impedance spectroscopy(EIS), cyclic voltammetry(CV), scanning electron microscopy(SEM) and atomic force microscopy(AFM). The [Fe(CN)6]3−/4− redox couple was used as a probe to characterize the nanose...

Phosphodiesterase-3 Enzyme Inhibitor Drug Milrinone Interaction with DNA and HSA: Electrochemical, Spectroscopic and Molecular Docking

In this study, the interaction between the phosphodiesterase-3 enzyme inhibitor drug milrinone and biomolecules was investigated by electrochemical, fluorescence spectroscopy, and molecular docking studies for the first time. The interaction between milrinone and biomolecules was investigated according to the decrease in deoxyguanosine oxidation signals of milrinone and calf thymus double-stranded deoxyribonucleic acid (ct-dsDNA) by cyclic voltammetry and differential pulse voltammetry. In fluorescence spectroscopy studies, a competitive study was conducted on ct-dsDNA by adding a well-known fluorescent methylene blue and ct-dsDNA solution. The fluorescent results showed that milrinone had a higher affinity for ct-dsDNA binding compared to methylene blue. Interaction studies show that milr...
