As Christians celebrate the Resurrection of Christ, history continued to happen while the priest was raising the host at mass and the Baptist minister was
For the past several years, we have been following the Savoia Marchetti Historical Group (SMHG) in Italy, and their efforts to build a faithful replica of the all-but extinct Savoia-Marchetti S.55X, the twin-hulled Italian flying boat which became globally-famous in July, 1933 when Italo Balbo lead 24 of them in formation from Orbatello, Italy out over the Atlantic Ocean and half way across the United States to appear at Chicago's Century of Progress International Exposition. Although Savoia-Marchetti manufactured more than 250 S.55s, just one complete survivor of the breed remains today sadly, preserved at the now-shuttered TAM museum in Brazil. That aircraft is the one which Commander João Ribeiro de Barros used in his 1927 crossing of the South Atlantic. But with no representative example of this important Italian design residing in the nation of its birth, nor the likelihood of obtaining one, the Savoia Marchetti Historical Group decided to construct a replica to fill this
Study investigates activity of enzymes immobilized on gold nanoparticles controlled by infrared laser irradiation
The activity of enzymes in industrial processes, laboratories, and living beings can be remotely controlled using light. This requires their immobilization on the surface of nanoparticles and irradiation with a laser. Near-infrared light can penetrate living tissue without damaging it.
The nanoparticles absorb the energy of the radiation and release it back in the form of heat or electronic effects, triggering or intensifying the enzymes catalytic activity. This configures a new field of study known as plasmonic biocatalysis.
Research conducted at the University of São Paulo s Chemistry Institute (IQ-USP) in Brazil investigated the activity of enzymes immobilized on gold nanoparticles controlled by infrared laser irradiation. An article reporting the results is published in
