The recall of 11 million Volkswagen diesel vehicles highlights the challenges of reducing emissions from fossil fuel-powered cars. Fortunately, there?s an alternative and it has zero emissions. The fuel-cell car is currently being developed by major automakers including Mercedes-Benz, Toyota and Hyundai.
Walter Mérida, director of UBC?s Clean Energy Research Centre (CERC), has been researching fuel-cell technology for more than 15 years. When Mercedes-Benz rolls out its new fuel-cell cars in a few years, they?ll feature Canadian technology.
What are some of the benefits of fuel cells?
Fuel cells convert hydrogen and other fuels into electricity quietly, efficiently, and without pollution. A fuel-cell car produces zero emissions. You?ll only see water coming out of the tailpipes. And it?s quickly refueled, unlike battery-powered cars which can take hours to recharge.
Fuel cells can be used to build a renewable, carbon-free energy system if you produce the hydrogen from ...

October Lab TourDSC_5773
from UBC Mechanical Engineering
(2015/10/3 4:12)
|
The Mechanical Engineering Department regularly hosts guided lab tours for high school students, first year students, incoming mechanical engineering students, or anyone interested in mechanical engineering. We will be hosting our first tour of the year on October 23rd from 1:00-2:30 pm .
Come meet some of our current MECH students and get their perspective on the department and program as they show you around our facilities. See the cool gadgets our student teams are working on and learn about the many different areas in which a mechanical engineer can apply his or her knowledge. Get a look at the cutting-edge technology inside our labs and see the kinds of research mechanical engineers can do. It’s a great chance to find out what our department is all about and what you can do with a mechanical engineering degree from UBC!
For those interested, there will also be a half-hour long advising session held after the tour where participants can ask questions about admission ...

Günstige Wafer für Solarzellen
from Fraunhofer Presseinformationen
(2015/10/1 16:00)
|
Siliziumwafer sind das Herzstück von Solarzellen. Sie herzustellen, ist jedoch nicht billig.Über 50 Prozent des reinen Siliziums werden zu Staub zerspant. Eine neue Herstellungsmethode von Fraunhofer-Forschern räumt auf mit diesen Materialverlusten: Die Hälfte des Rohstoffs und 80 Prozent Energie lassen sich so einsparen.

Harnsteine gehören allgemein zu den häufigsten Erkrankungen. Eine konsequente Nachsorge kann der erneuten Steinbildung nach der Operation vorbeugen. Hierfür muss jedoch die Zusammensetzung des Steins bekannt sein. Fraunhofer-Forscher entwickeln ein System, das die direkte Analyse nach dem Eingriff erlaubt.

Auf dem Vorfeld des Flughafens herrscht viel Verkehr: Schlepper, Tankwagen und Busse bewegen sich emsig um den Jet. Dabei droht die Gefahr von Zusammenstößen. Ein verbessertes Ortungssystem erhöht künftig die Sicherheit und lässt die logistischen Prozesse effizienter werden?vorhandene Flughafenkapazitäten werden besser genutzt.

Eiweiße aus Reis?Rohstoff statt Abfall
from Fraunhofer Presseinformationen
(2015/10/1 16:00)
|
Extrahiert man Reisstärke aus dem Reis, bleiben Eiweiße zurück. Ein wertvoller Rohstoff, der bislang von Reisstärkeproduzenten teuer entsorgt wird. Ein neues Verfahren spaltet das Eiweißnun in kleinere Stücke, in Peptide, und reinigt sie. Die Peptide wiederum könnten in Kosmetika und Nahrungsergänzungsmitteln wertvolle Dienste leisten.

In der neuen BMW 7er Reihe erleichtert ein Lichtteppich in Form eines strahlenförmigen Lichtmusters den Einstieg bei Dunkelheit. Fraunhofer-Forscher haben dazu spezielle Mikrooptiken entwickelt, die das Licht vom Fahrzeugboden gezielt auf den Einstiegsbereich lenken.

Quantum Dots haben für einen Qualitätssprung bei der Farbwiedergabe in LC-Displays gesorgt. Diese cadmiumbasierten Nanokristalle entpuppten sich allerdings als umweltschädlich. Fraunhofer-Forscher arbeiten gemeinsam mit einem Industriepartner an einer vielversprechenden Alternative: Quantum Dots aus Indiumphosphid.

TDPS presents The Cherry Orchard, Anton Chekhov?s tragicomic tale of family, social status and retur
from UC Berkeley Department of Theater, Dance, and Performance Studies
(2015/9/30 2:52)
|
Berkeley, CA ? This fall the UC Berkeley Department of Theater, Dance and Performance Studies (TDPS) presents Anton Chekhov ?s THE CHERRY ORCHARD , directed by TDPS senior lecturer Lura Dolas . Combining heartfelt performances, intricately-constructed period costumes, original music and a new translation by Libby Appel, TDPS?s production illuminates the humanity at the heart of this classic tale of twentieth-century social upheaval.
THE CHERRY ORCHARD opens Friday, October 23, 2015 at Zellerbach Playhouse on the UC Berkeley Campus and runs through Sunday, November 1, 2015. Tickets are $13-$20, and can be purchased online through the TDPS Box Office or at the door.
About THE CHERRY ORCHARD
THE CHERRY ORCHARD , Chekhov?s great classic and the last play written before his death, features a rich tapestry of humanly-flawed characters trapped on the wheel of fortune. As Russia rolls toward revolution, Lyubov Ranevskaya, a once-wealthy landowner, returns home after years ...

October 29, 2015?MECH Seminar?Topics in Microfluidics and MEMS
from UBC Mechanical Engineering
(2015/9/25 1:41)

Title: Topics in Microfluidics and MEMS
Speaker: Dr. Boris Stoeber, Associate Professor, Department of Mechanical Engineering, UBC
Date: Thursday, October 29, 2015
Time: 12:30 – 2:00pm
Location: Kaiser 2020
Abstract:
This talk gives a high-level overview of some of the work done in my research group. Our research topics primarily include small-scale systems with focus areas in microfluidics and sensing technology. Our work includes some more fundamental research as well as more applied projects on innovative device concepts.
(1) Microneedles are small mechanical structures that provide an interface with the human skin for drug delivery or biosensing. Our solvent casting process involves interesting flow physics and allows creating arrays of hollow microneedles for these applications. (2) We have developed flow control concepts using thermally responsive fluids that solidify reversibly at elevated temperatures. (3) We separate particles in air by size insid ...
