This study aimed to elucidate the perceptions and mental models of 5th-grade secondary school pupils about shadows, solar eclipses and lunar eclipses through drawings. A total of 443 pupils studying at public schools in Afyonkarahisar participated in the study. It was conduc...
Australia's national energy system is heavily reliant on coal-fired power plants and requires quick action to decrease CO2 emissions in order to meet the Paris climate change agreement by 2030. As a good alternative to coal power, renewable resources can produce the required energy for Australia ...

While TMDs hold great promise, research experiments to date have struggled to change more than 2% of the sunlight they absorb into electricity. But the scientists believe they could practically reach 27% efficiency with electrical improvements. That would be comparable with today’s top solar panels...
Helical coil heat exchangers are widely used in various processes due to the advantages compared to other (tubular) types of heat exchanger, such as easy integration to the system, relatively simple design and manufacturing, operation at high pressure, suitable under conditions of laminar flow or ...
The sheet resistance of these films were measured using a four-probe resistivity test system. Raman spectra were obtained with a Renishaw 2000 Raman system (Renishaw, London, UK) with a 514 nm laser. Optical photographs were obtained by an optical microscope (Axio Scope A1, Zeiss, Oberkochen,...
serving both as a working fluid and a vapor transport medium, does not create a bottleneck in the system. Hence, integrating additional heating strategies, such as stage temperature boosting, could substantially enhance MD device performance. Leveraging low-grade waste heat or solar thermal energy, ...
