Study uncovers the role of exciton lifetimes in enabling highly efficient organic solar cells
Organic photovoltaics are a third-generation solar cell technology made of electron donor and electron acceptor materials instead of conventional semiconductor p-n junctions. The performance of this...
A protocol to minimize the thermodynamic cost of erasing a single bit over a given amount of time
Stochastic thermodynamics theory is a framework that delineates the amount of heat, dynamics and entropy in small (i.e., mesoscopic) systems that are far from a state of thermodynamic equilibrium....
Do explanations for data-based predictions actually increase users’ trust in AI?
In recent years, many artificial intelligence (AI) and robotics researchers have been trying to develop systems that can provide explanations for their actions or predictions. The idea behind their...
Exploring prediction errors that can influence human perceptions of time
Humans can sometimes perceive the passing of time differently, for instance, feeling as though an hour passed very quickly or that a few minutes went by extremely slowly. This suggests that the...
Study sets limits on the flux of heavy compact objects using data from the Pi of the Sky project
Strangelets, and specifically nuclearites, their heavy species, are very dense, compact and potentially fast objects made of large and roughly equal numbers of up, down and strange quarks, which may...
Radiation-immune and repairable chips to fabricate durable electronics
To operate safely and reliably in outdoor environments, electronic devices should be resistant to a wide variety of external factors, including radiation. In fact, high-energy radiation can damage...
RoomShift: A room-scale haptic and dynamic environment for VR applications
Researchers at University of Colorado Boulder's ATLAS Institute have recently created RoomShift, a haptic and dynamic environment that could be used to support a variety of virtual reality (VR)...
A 3D-printed tensegrity structure for soft robotics applications
Tensegrity is a design principle that has often been applied by artists, architects and engineers to build a wide range of structures, including sculptures, frames and buildings. This principle...
Commercial battery cells that can monitor their own chemical and thermal state
Battery technology can sometimes be unstable and volatile, two characteristics that impair its safety and reliability. Actively monitoring the chemical and thermal state of battery cells over time...
Using deep learning to control the unconsciousness level of patients in an anesthetic state
In recent years, researchers have been developing machine learning algorithms for an increasingly wide range of purposes. This includes algorithms that can be applied in healthcare settings, for...
