Topological Soft Materials for All-Optic Low Energy Photonics

submitted by: RASEIBoulder
The existing infrastructure for managing the flow of information along the photonic pathways and in our computers is in most segments based on electrically encoded information and the transport of electric charges using the electric force. This process is limiting the speed of signal propagation and is costly in terms of energy dissipation. The predicted worldwide energy consumption of data centers for 2050 is approaching the electric energy generated in the European Union in 2010! It is...

Approaches to Evaluating and Improving Lithium-Ion Battery Safety

submitted by: RASEIBoulder
As lithium-ion battery technologies mature, the size and energy of these systems continues to increase for emerging applications in transportation, grid storage, military use and aerospace. In fact, broadening the application space for lithium-ion batteries from the consumer electronics industries to these emerging markets increases their size from 1-50 Wh batteries for smart phones and laptops to >50 kWh for electric vehicles (EVs) and MWh scale for utility storage systems. As these...

Making Most of the Absorbed Photon: New Insights into Carrier Multiplication in Semiconductor Nanostructures

submitted by: RASEIBoulder
Carrier multiplication (CM) or multiexciton generation (MEG) is a process whereby absorption of a single photon produces multiple electron-hole pairs (excitons). CM could benefit a number of solar-energy conversion technologies, most notably photocatalysis and photovoltaics. This presentation overviews recent progress in understanding of the CM process in semiconductor nanocrystals, motivated by an outstanding challenge in this field - the lack of capability to quickly discern between...

Systems as the Driver for Synthetic Biology

submitted by: RASEIBoulder
We now possess the ability to read and write DNA. These tools are not only revolutionizing biotechnology but also the basic life sciences as well. The challenge is that we are still learning the grammar. In other words, we often do not know which genetic perturbations to make in order to alter the behavior of an organism. As a result, synthetic biology still involves much trial and error. Moreover, we are still far from the point where we can engineer new organisms from scratch – rather,...

Aptamer Data from Base Pair Biotechnologies

submitted by: BasePairBio

Aptamers have until recently been tightly held by IP restrictions, Base Pair Biotechnologies Founder Bill Jackson presents information and data they have generated on aptmers in diverse assays such as biosensor and lateral flow. Presentation is from the American Society for Cell Biology meeting Dec 16, 2012
