Interference-free cabling

Interference-free cabling

Martin Tenhumberg and Werner Wölfle, Traco Power

Long lines for distributed loads can emit and be susceptible to interference which can affect the connected loads. However, the loads work without disruption as long as a few basic rules are observed when it comes to cabling. Moderndevices and systems are generally complex, their electrical/electronic components

Excited-state intramolecular proton transfer (ESIPT) makes possible organic light-emitting diodes (OLEDs) that are highly efficient by creating the necessary conditions to enable thermally activated delayed fluorescence (TADF). After excitation of the emitting molecule, a hydrogen atom -- technically, just its nucleus -- is transferred to a different atom in the same molecule through a process called ESIPT. The reconfigured molecule can then undergo TADF to convert a high fraction of the excitations into light. Following emission, the molecule returns to its original state. This mechanism increases the molecular design strategies available for the creation of novel and improved light-emitting materials.

Harnessing Hopping Hydrogens for High-Efficiency OLEDs

Kyushu University, OPERA

Renewed investigation of a molecule that was originally synthesized with the goal of creating a unique light-absorbing pigment has led to the establishment of a novel design strategy for efficient light-emitting molecules with applications in next-generation displays and lighting. Researchers at Kyushu Universit

Modular, Scalable Off-Grid Energy Solution Requires no Professional Installation

Choosing an off-grid power solution is like predicting the future. It’s hard. You need to predict the amount of energy that the system will require if you add appliances, increase production, add infrastructure, or simply turn on a hair dryer. Currently, off-grid power solutions require a level of custom
