Alessandro Marangoni
Alessandro Marangoni (born 1979) is an Italian classical pianist. He studied piano with Marco Vincenzi, and, after a diploma summa cum laude, continued his studies at the Scuola di Musica di Fiesole with Maria Tipo. He also studied philosophy, graduating from the Università di Pavia with honors with a thesis about Fernando Liuzzi's philosophy of music. Marangoni has won a number of awards, both in his native Italy and abroad, including, in 2007, the prestigious Amici di Milano International Prize for Music. He has performed in many European countries, and in the United States, as a soloist and as a member of chamber groups. He has worked with many of Italy's leading musicians, including Mario Ancillotti, Aldo Ceccato, Valentina Cortese, Quirino Principe, the Nuovo Quartetto Italiano and Carlo Zardo. Marangoni has also performed more than one hundred concerts on Second Life, under his avatar Benito Flores. He has recorded music by composers such as Rossini, Muzio Clementi, an ...

Carlo Marangoni
Carlo Giuseppe Matteo Marangoni (29 April 1840 – 14 April 1925) was an Italian physicist. Biography Marangoni graduated in 1865 from the University of Pavia under the supervision of Giovanni Cantoni with a dissertation entitled "" ("On the spreading of liquid droplets"). He then moved to Florence where he first worked at the "Museo di Fisica" (1866) and later at the Liceo Dante (1870), where he held the position of High School Physics Teacher for 45 years until retirement in 1916. He primarily studied surface phenomena in liquids, and the Marangoni effect and the Marangoni number are named after him. He also contributed to meteorology and invented a ''Nefoscopio'' to observe clouds. Aspirator and Compressor Marangoni simplified the aspirator for the measurement of gas. A common flaw in aspirator were inaccurate measurements caused by ascending of air The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds t ...

Marangoni Effect
The Marangoni effect (also called the Gibbs–Marangoni effect) is the mass transfer along an interface between two phases due to a gradient of the surface tension. In the case of temperature dependence, this phenomenon may be called thermo-capillary convection (or Bénard–Marangoni convection). History This phenomenon was first identified in the so-called "tears of wine" by physicist James Thomson (Lord Kelvin's brother) in 1855. The general effect is named after Italian physicist Carlo Marangoni, who studied it for his doctoral dissertation at the University of Pavia and published his results in 1865. A complete theoretical treatment of the subject was given by J. Willard Gibbs in his work ''On the Equilibrium of Heterogeneous Substances'' (1875-8). Mechanism Since a liquid with a high surface tension pulls more strongly on the surrounding liquid than one with a low surface tension, the presence of a gradient in surface tension will naturally cause the liquid to flow away fr ...

Marangoni Number
The Marangoni number (Ma) is, as usually defined, the dimensionless number that compares the rate of transport due to Marangoni flows, with the rate of transport of diffusion. The Marangoni effect is flow of a liquid due to gradients in the surface tension of the liquid. Diffusion is of whatever is creating the gradient in the surface tension. Thus as the Marangoni number compares flow and diffusion timescales it is a type of Péclet number. The Marangoni number is defined as: \mathrm = \dfrac A common example is surface tension gradients caused by temperature gradients. Then the relevant diffusion process is that of thermal energy (heat). Another is surface gradients caused by variations in the concentration of surfactants, where the diffusion is now that of surfactant molecules. The number is named after Italian scientist Carlo Marangoni, although its use dates from the 1950s and it was neither discovered nor used by Carlo Marangoni. The Marangoni number for a simple liquid of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clara Marangoni
Carla Marangoni, better known as Clara Marangoni (13 November 1915 – 18 January 2018), was an Italian gymnast who competed in the 1928 Summer Olympics. She was born in Pavia as "Carla," but she is usually (mistakenly) mentioned in the official statistics as ''Clara''. In 1928, she won the silver medal as member of the Italian gymnastics team and was therefore among the first Italian women to win an Olympic medal. She was also the last surviving athlete from 1928 Summer Games. Marangoni died on 18 January 2018 at the age of 102 years. She was the 6th and last youngest medalist from the Olympic Games (12 years and 270 days) until the silver medal in skateboarding from the Brazilian Rayssa Leal in 2021 (13 years and 203 days).
