LIGHT + MATTER. “Other phenomena where light affects the movement of electric charges include the photoconductive effect (also known as photoconductivity or photoresistivity), the photovoltaic effect, and the photoelectrochemical effect.” https://lnkd.in/eDZvjevE View in LinkedIn

IMPACT. “Research on the photoelectric effect resulted in important steps in understanding the quantum nature of light and electrons and influenced the formation of the concept of wave–particle duality.” https://lnkd.in/eDZvjevE View in LinkedIn

PHOTOELECTRIC EFFECT. “Emission of conduction electrons from typical metals usually needs a few electron-volts, equivalent to short-wavelength visible or ultraviolet light.” https://lnkd.in/eDZvjevE View in LinkedIn

Palamos shrimp are highly prized in Catalonia and owe their color and taste to a very deep finger of the Mediterranean that upwells nutrients near this fishing town. View in LinkedIn

MAGIC. “Acoustic levitation is “a technique that used mechanical energy of sound to levitate and manipulate materials, has been notably advanced over the past decade (https://lnkd.in/eRHAuxw9), levitating almost any type of materials. Acoustic levitation is also emerging as a strong candidate for creating mixed-reality (MR) interfaces that can seamlessly blend the digital and physical worlds.” https://youtu.be/yrZSp2n-KFw View in LinkedIn

LOCUST AGGREGATION PHEROMONES. “It is now clear that chemical ecology plays an important part in the life of locusts and that a bouquet of various odorants may act at different times during their development and adult maturation and, therefore, may have different effects at different times. females preferentially mate with males emitting a high concentration of the volatiles phenylethyl alcohol (PEA) and (Z)-3-nonen-1-ol (3-NOL) and this also affected successful hatching of their larvae. Recently, a careful study of Guo et al. (2020) identified 4-vinylanisole or 4-methoxystyrene as an aggregation pheromone in Locusta migratoria.” https://lnkd.in/eDTzyGJT View in LinkedIn

PHOTON ENERGIES. “The photoelectric effect necessitates photons with energies approaching zero (in the case of negative electron affinity) to over 1 MeV for core electrons in elements with a high atomic number.” https://lnkd.in/eDZvjevE View in LinkedIn

NOBEL RECOGNITION. “Siegbahn received the Nobel Prize for Physics in 1981, in recognition of his wide-ranging efforts to develop XPS into a useful analytical tool. In parallel with Siegbahn's work, David Turner at Imperial College in the UK developed ultraviolet photoelectron spectroscopy (UPS) on molecular species using helium lamps.” (XPS = X-ray photoelectron spectroscopy). https://lnkd.in/eDZvjevE View in LinkedIn

EXPERIMENTAL PROOF. “1914, Robert Millikan's experiment supported Einstein's model of the photoelectric effect. Robert Millikan (22 March 1868–19 December 1953, American experimental physicist) was awarded the Nobel Prize in Physics in 1923 for “his work on the elementary charge of electricity and on the photoelectric effect.” https://lnkd.in/eDZvjevE View in LinkedIn

COMMERCIALIZATION. “In cooperation with Siegbahn, a small group of engineers at Hewlett-Packard in the USA, produced the first commercial monochromatic XPS instrument in 1969.” (XPS = X-ray photoelectron spectroscopy). https://lnkd.in/eDZvjevE View in LinkedIn
