The recent MRSEC Teacher Workshop at UCSB was a Great Success. Junior High and High School math and science teachers from Santa Barbara, Ventura and Los Angeles Counties visited the UCSB Materials Research Laboratory for a day of curriculum presentations and workshops.
To a packed audience of over 200 students and local residents, the UCSB MRL supported a public lecture on the subject of solid state lighting, emphasizing the promise of a much cleaner, more efficient, and longer-lasting lighting source. Santa Barbara architect
UCSB MRL researchers have recently developed a new way of seeing beneath clothing and other materials using a THz imaging system that employs a photoconductive switch for illumination and a zero-biased, Schottky diode for detection. Just like Superman, this novel Terahertz system penetrates textiles, in this case denim cloth from jeans, but does not use ionizing radiation and therefore poses a significantly reduced risk to human health when compared to x-rays.
Graphitic carbon - structural forms of the element that are constructed exclusively from carbon atoms having trigonal planar coordination - is ordinarily produced under drastic physical and conditions, typically at temperatures in excess of 500° C. Columbia MRSEC scientists have uncovered a process by which this form of matter can assemble at temperatures as low as 110° C. During their development of a low-temperature synthesis of nanocrystals of iron oxides, Drs.
Expansion of the McNair CITIES ProgramThe MRSEC developed a new program to help enhance the curriculum of NYC high schools called the Ron McNair Curriculum Integration To Interactively Engage Students (CITIES) Program. The goals of the program are to increase student engagement and to motivate students to enjoy learning and to educate the public. In 2005, the MRSEC brought the program to a Enterprise, Business, and Technology (EBT) High School in Brooklyn.
"Perfectly hydrophobic" surfaces have been developed by McCarthy and are being applied to low friction motion and lubrication McCarthy and Crosby. Shown in the image is an "18-wheel vehicle", prepared by treating a dimethyldichlorosilane-treated quartz plate with UV/ozone through a mask containing 18 hexagonally arrayed 1 mm diameter holes spaced by 4 mm on center.
Composites of polymers and inorganic nanoparticles offer tremendous promise for the optimization of mechanical properties. Although many claims of improved properties and balanced optimization can be found in the scientific literature over the past several decades, very little fundamental insight has been provided for the true "nano" effect on mechanical properties.
Myelin figures are long thin cylindrical structures that grow when water is added to the concentrated lamellar phase of certain surfactants such as soap. The Sidney Nagel and Tom Witten groups at the University of Chicago developed a method to produce isolated myelin figures, based on previous investigations of ring stain formation pioneered at the MRSEC. This allowed them to study their growth and stability in detail.
