2:39 PM | I buchi neri esistono…davvero!
In questi giorni, i titoli dei media online e di alcuni blog stanno riportando la notizia secondo cui “i buchi neri non esistono”. In realtà non è proprio così! I buchi neri esistono eccome. Lo sappiamo dalle osservazioni astronomiche. Inoltre, lo sappiamo dallo studio delle orbite delle stelle in vicinanza del centro galattico, dove risiede […]

2:13 PM | Solar cell compound probed under pressure
Gallium arsenide a semiconductor composed of gallium and arsenic is well known to have properties that promise practical applications. In the form of nanowires it has particular potential for use in solar cell manufacture and optoelectronics in many of the same applications that silicon is commonly used. But its natural semiconducting ability requires tuning to make it more desirable for use in manufacturing. New work offers a novel approach to such tuning.

12:43 PM | Trains of Clocks
My Gen Ed relativity course has mostly been me lecturing about stuff to this point, so on Wednesday I decided to shake things up a bit and convert a chapter of David Mermin’s It’s About Time. The idea was to get students up and moving around a bit, and actually making some measurements of stuff.…

11:30 AM | Victor Celorio...
“The first time I saw a laser printer, I thought about making books with it.”Born July 27, 1957 in Mexico City. Victor is an inventor who obtained patents for the technology popularly known as InstaBook or Book On Demand, as well as that of Distributed Printing technology in which an e-book is distributed among as many printing centers as required for immediate production and delivery, thereby creating a vast network of digital bookstores and libraries.At a young age Celorio had a […]

11:00 AM | A Line in the Sand...
Please Do Not Spin the Moon...rather than our heads. Although, I think this might be an Emu.The National Academies - Science, Engineering, Medicine, Research - has a page called "America's Climate Choices." I feel our coy obfuscation for the moneyed has reduced our time necessary to respond. As a democratic republic, we should demand more of our elected officials and the sacred trust of representative government.Especially in this country, there's obviously a litmus test on how much science one […]

8:08 AM | How To Organise An Outreach Event
Public engagement: love it or hate it, it’s part of modern life as a researcher. For the record, I love it, and I’ve done quite a bit of outreach in my 2 years as CM-DTC outreach co-ordinator for the St Andrews area. Since I’m passing on the baton, I made a by-no-means-complete checklist of all […]

7:59 AM | Self-organized indium arsenide quantum dots for solar cells
Researchers exploit the self-organization of semiconducting nanocrystals by the Stranski-Krasnov (SK) mode of crystal growth for producing ordered, highly dense, and highly uniform quantum dots. This bottom-up approach yields much better results than the conventional photolithographic or top-down methods widely used for the fabrication of nanostructures.

Un gruppo di astronomi della University of Utah guidati da Anil Seth hanno identificato nella galassia nana ultracompatta, la più piccola che conosciamo, nella quale risiede un buco nero supermassiccio. La scoperta è alquanto sorprendente e suggerisce il fatto che i buchi neri di grandi dimensioni possono essere molto più comuni di quanto ipotizzato. I risultati […]

10:08 PM | Profumo di particelle
Direi che oggi pomeriggio è stato un bel respirare, al Palazzo Brera. Cristina Lazzeroni dell'Università di Birmingham è venuta alle 18 (come avevo scritto nel post precedente) per raccontare del bosone di Higgs, del modello standard e di materia e antimateria. E' una sperimentale presso l'esperimento LHCb al CERN, l'esperimento dedicato proprio alla ricerca su uno dei grandi misteri dell'universo: perché in esso c'è un eccesso di materia (e d'altra parte se […]

7:33 PM | Colliders fit for gods
Neutron stars — the incredibly dense, weird remnants of stars more massive than the Sun — are like nothing on Earth. They occupy a corner of physics where strong gravity, high temperature, and intense nuclear forces combine. And when two neutron stars collide, they create some of the most powerful explosions in the cosmos, prosaically […]

  Laboratory work is getting fairly heated here at A&M. Equipment is becoming available for use, and as each new bouncing bundle of joy makes its way into the laboratory, it has to be fully characterized. Many times, sadly, the initial characterization is that the ‘new to us’ piece of equipment is just flat out [...]

2:20 PM | Healing electronics with light
As we are moving into an era of flexible and wearable electronic devices, one challenge that arises is an increased vulnerability to mechanical failure. Relatively small damages such as tiny cracks along the electrical conductive pathway caused by the bending, twisting and folding of such devices could easily cause the entire gadget to fail. Researchers have now demonstrated light-powered healing of an electrical conductor. They show that green light even with low intensity has potential to […]
