Once bound with a specific target, a NanoCluster Beacon lights up, emitting fluorescence approximately 200 times greater than in the unbound state and easily viewed by the naked eye under ultraviolet light. The beacons come in an array of colors for multiplexed analyses, are more photostable than beacons used today, and can be turned on and off reversibly. Inexpensive, easy to use, and reversible, NanoCluster Beacons are superior molecular probes for detecting specific targets, human oncogene (cancer) sequences, and molecular disease sequences such as sickle cell anemia.
Revolutionizing Deepwater Oil-Well Drilling
TAPSS, or Trapped Annular Pressure Shrinking Spacer, is a spacer fluid developed by Robert Hermes of LANL, in collaboration with Chevron Energy Technology Company, Baker Hughes Incorporated's Drilling Fluids Unit, and Lucite International Ltd., to help prevent catastrophes in offshore oil-well drilling. Conventional spacer fluids are placed between oil well casings to secure the well and balance the pressure exerted by the surrounding geological formations. Most of these fluids expand when heated during drilling, causing potential pressure build ups and disastrous oil spills. TAPSS, on the other hand, shrinks when heated and can be used to offset any thermal expansion from the other fluids. TAPSS is formulated with enough methyl methacrylate to counteract the expansion of conventional spacer fluids. This new spacer is not difficult to use, is self-functioning, and requires minimal time to install.
TAPSS can be applied to any well around the world and will continue to work for the full life of the well, making it both effective and practical.
Thorium Is Now Green
Th-ING was developed by Jaqueline Kiplinger and Thibault Cantat as a straightforward, cost-effective, and safe method to produce thorium. Thorium is an element cap
