The nervous system's circuitry is linked together via intercellular junctions known as synapses, and signal transmission across these connections depends on neurotransmitters?specific chemicals that directly deliver excitatory or inhibitory signals from one neuron to another. Scientists are now able to monitor receptor activity in living cells with unprecedented precision.
A team of Brown University scientists has pinpointed why carbon nanotubes tend to block a critical signaling pathway in neurons. It's not the tubes, the team finds, but the metal catalysts used to form the tubes.
A hybrid of silicon nanocircuits and biological components that mimics some of the processes that control the passage of molecules into and out of cells has been created by a team of scientists from UC Davis, Lawrence Livermore National Laboratory and UC Berkeley.
Untersuchungen zeigen, dass Metallofullerene geordnete supramolekulare Strukturen mit unterschiedlichen Orientierungen ausbilden. Durch gezielte Manipulation dieser Orientierungen koennten Daten gespeichert und wieder ausgelesen werden.
Six project proposals from the Nanyang Technological University (NTU) have received research funding from the National Research Foundation (NRF), following its second call for proposals under the Proof of Concept (POC) scheme.
Materialwissenschaftler der Fachhochschule Muenster und ein Entwicklerteam der Evonik Degussa GmbH in Marl wollen mit neuartigen Nanopartikeln das Herstellungsverfahren von elektronischen Bauelementen revolutionieren.
A University of York scientist has been awarded a Royal Society Dorothy Hodgkin Fellowship for her research on smart polymer materials that could eventually be used as sensors to detect biological materials and pollutants.
The research improves the method of accurately forecasting the location and nature of potential failures in electronic devices due to cracks in the integrated materials, promising to help increase the durability and reliability of today?s electronic devices and potentially even aircraft and bridges.
