“…It has also been widely used as the photoanode for dye-sensitized solar cells and coatings for self-cleaning surfaces, biomedical implants, and nanomedicine. …”

“…The expansion of energy production from renewable sources and the tendency towards the concentration of such installations (e.g. large wind farms or solar parks) is increasingly met with opposition from the public. …”

“…Thanks to successful use of flexibility resources - from stronger grids and interconnections to demand-side measures, affordable storage and dispatchable power supply - many countries have already securely and efficiently integrated significant shares of variable renewables (VRE) in their electricity generation. As wind and solar continue to grow as a proportion of generation, system level surpluses and periods of lower generation will eventually expand beyond hour-to-hour or daily variations to seasonal timescales. …”

“…Studies of fluid flow and heat transfer in a porous medium have been the subject of continuous interest for the past several decades because of the wide range of applications, such as geothermal systems, drying technologies, production of thermal isolators, control of pollutant spread in groundwater, insulation of buildings, solar power collectors, design of nuclear reactors, and compact heat exchangers, etc. …”

“…This Special Issue of IJMS is dedicated to providing a comprehensive overview of the identified risks and focus on how oxidative stress specifically could impact major organ systems when exposed to space-relevant conditions such as cosmic/galactic radiation, solar particle events, hypogravity, hyperoxia and hypoxia or a combination of stressors…”

“…There is a new world order in electrical energy production. Solar and wind power are established as the low-cost leaders. …”

“…The exciting world of crystalline silicon is the source of the spectacular advancement of discrete electronic devices and solar cells. The exploitation of ever changing properties of crystalline silicon with dimensional transformation may indicate more innovative silicon based technologies in near future. …”

“…Un relat fantàstic on predomina el punt de vista tecnològic : metros penjants automatitzats, automòbils silenciosos, un enllumenat elèctric que és comparable a la llum solar... Una ciutat dominada pels diners i les ciències mecàniques, sota el control cultural de l'Estat, mentre que la cultura clàssica només la defensen grups marginats, els quals, humiliats per la indiferència general, acaben vençuts per la misèria i la fam…”
