Solar energy is a green and sustainable clean energy source. Its rational use can alleviate the energy crisis and environmental pollution. Directly converting solar energy into heat energy is the most efficient method among all solar conversion strategies. Recently, various environmental and energy applications based on nanostructured photothermal materials stimulated the re-examination of the interfacial solar energy conversion process. The design of photothermal nanomaterials is demonstrated to be critical to promote the solar-to-heat energy conversion and the following physical and chemical processes. This review introduces the latest photothermal nanomaterials and their nanostructure modulation strategies for environmental (seawater evaporation) and catalytic (C1 conversion) applications. We present the research progress of photothermal seawater evaporation based on two-dimensional and three-dimensional porous materials. Then, we describe the progress of photothermal catalysis based on layered double hydroxide derived nanostructures, hydroxylated indium oxide nanostructures, and metal plasmonic nanostructures. Finally, we present our insights concerning the future development of this field.

There is a strong and growing worldwide research on exploring renewable energy resources. Solar energy is the most abundant, inexhaustible and clean energy source, but there are profound material challenges to capture, convert and store solar energy. In this work, we explore 3C-SiC as an attractive material towards solar-driven energy conversion applications: (i) Boron doped 3C-SiC as candidate for an intermediate band photovoltaic material, and (ii) 3C-SiC as a photoelectrode for solar-driven water splitting. Absorption spectrum of boron doped 3C-SiC shows a deep energy level at ~0.7 eV above the valence band edge. This indicates that boron doped 3C-SiC may be a good candidate as an intermediate band photovoltaic material, and that bulk like 3C-SiC can have sufficient quality to be a promising electrode for photoelectrochemical water splitting.

Issues related to global energy and environment as well as health crisis are currently some of the greatest challenges faced by humanity, which compel us to develop new pollution-free and sustainable energy sources, as well as next-generation biodiagnostic solutions. Optical functional nanostructures that manipulate and confine light on a nanometer scale have recently emerged as leading candidates for a wide range of applications in solar energy conversion and biosensing. In this review, recent research progress in the development of photonic and plasmonic nanostructures for various applications in solar energy conversion, such as photovoltaics, photothermal conversion, and photocatalysis, is highlighted. Furthermore, the combination of photonic and plasmonic nanostructures for developing high-efficiency solar energy conversion systems is explored and discussed. We also discuss recent applications of photonic–plasmonic-based biosensors in the rapid management of infectious diseases at point-of-care as well as terahertz biosensing and imaging for improving global health. Finally, we discuss the current challenges and future prospects associated with the existing solar energy conversion and biosensing systems.

When incubated anaerobically, in the light, in the presence of C2H2 and high concentrations of H2, both Mo-grown Anabaena variabilis and either Mo- or V-grown Anabaena azotica produce large amounts of H2 in addition to the H2 initially added. In contrast, C2H2- reduction is diminished under these conditions. The additional H2-production mainly originates from nitrogenase with the V-enzyme being more effective than the Mo-protein. This enhanced H2-production in the presence of added H2 and C2H2 should be of interest in approaches to commercially exploit solar energy conversion by cyanobacterial photosynthesis for the generation of molecular hydrogen as a clean energy source

Solar energy represents one of the future energy sources with a high potential, used as an alternative to conventional methods, especially during summer. The advantages of using solar energy are multiple, this type of energy being virtually endless and free, and its use has no negative effects on the environment, being regarded as a clean energy source. Solar energy has multiple applications in agriculture, one of its benefits being that it is used for dryers as an alternative energy source, especially in regions with a high solar potential. In this paper different types of fruits and vegetable dryers, nationally and abroad are presented, as well as results obtained from different methods of solar dryers.

Sun comes into prominence as both a strong and clean energy source. Because of its being inexhaustible and creating an effect reducing import dependency, a noticeable progress has been made in solar-oriented technologies in recent years. In this regard, Germany as the pioneer in world, China whose installed solar capacity has overtaken Germany, and the USA and Japan which caught up Germany became benefited from solar energy significantly nowadays. Besides, the EU countries like Italy, England, France, Spain and Belgium are also raising their installed solar capacities. Turkey has relatively high solar potential compared to the EU countries. However, it is not benefiting from solar energy sufficiently. Because its setup costs are still higher than other sources, solar production requires to be carried out R&D activities intensively. For these R&D activities there is a need for big budgets. Developed countries mentioned above could have been successful in allocating these budgets. Turkey as a developing country has difficulties in this respect. The purpose of this paper is to reveal required policies and works to raise installed solar capacity and benefit more from solar energy in Turkey. In this context, primarily, policies imposed in leader countries in world with regards to benefit from solar energy will be examined. Thereafter, imposed policies and developments in Turkey until today in this respect will be mentioned. Consequently, suggestions will be made for Turkey in light of experiences of the countries that could have succeeded to benefit from solar energy by higher rates in primary sources.
