Ez a szirup garantáltan megszabadít a hason felgyülemlett zsírtól és a fölöslegesen elraktározódott folyadéktól. Emellett pedig javítja az agy működését, a memóriát, a hallást és a látást is. A keverék akkor a leghatékonyabb, ha valamilyen kardió edzéssel kombináljuk. Fő összetevője a friss torma, amely gazdag C-, B1-, B6-, B12-vitaminban, káliumban, magnéziumban és foszforban. A torma […]

(Phys.org)—As lithium resources continue to decline worldwide, the next generation of portable electronics will most likely be powered by something other than Li-ion batteries. One potential candidate is the sodium-ion (Na-ion) battery, which stands out because sodium is cheaper, non-toxic, and more abundant than lithium.

Light is both a wave and a particle, but taking a photo of these two states has proven difficult.

Diatoms play an important role in water quality and in the global climate. They generate about one fourth of the oxygen in the Earth's atmosphere and perform around one-quarter of the global CO2 assimilation, i.e. they convert carbon dioxide into organic substances. Their light receptors are a crucial factor in this process. Researchers at the Leipzig University and the Helmholtz Centre for Environmental Research have now discovered that blue and red light sensing photoreceptors control the…

Organic light emitting diodes (OLEDs), which are made from carbon-containing materials, have the potential to revolutionize future display technologies, making low-power displays so thin they'll wrap or fold around other structures, for instance.

Researchers have successfully demonstrated how to both enhance light emission and capture light from metamaterials embedded with light emitting nanocrystals. The breakthrough could lead to a range of applications including ultrafast LEDs, nanoscale lasers and efficient single photon sources.

Nemrég járt a Wigner FK-ban (a Plazmafizikai Osztályon) Magyarósi Csaba vlogger, aki a fúzióról érdeklődött, majd meglátogatta az ITER-t Dél-Franciaországban ahol magyar mérnökökkel is beszélgetett

HU: 2015. január 19-én elindult A fény és a fényalapú technológiák nemzetközi éve. A nyitóünnepségre az UNESCO párizsi központjában került sor. Az eseményen felszólalt öt Nobel-díjas is: Ahmed Zewail (A fény és az élet), Steven Chu (Energia és a klímaváltozás: kihívások és lehetőségek), William Phillips (Einstein, idő és fény), Serge Haroche (Fény és kvantum) és Zhores Alferov (A fény hatásos létrehozása és konvertálása).
