Evercloak's HVAC technology gets government funding boost

Canada-based Evercloak's HVAC technology recently received a funding boost, with CAD$1.1 million (over USD$807,000) in funding from Natural Resources Canada's Energy Innovation Program (EIP).

The EIP funding supports a $1.8M project enabling Evercloak to accelerate the development of their membrane-based system, which can cut the energy required for air conditioning and dehumidification by up to 50%. According to the Company's founder and CEO, Evelyn Allen, those reductions will be crucial as global temperatures rise.

Researchers use engineered graphene material to improve the performance of intraneural peripheral nerve electrodes

Limb neuroprostheses aim to restore motor and sensory functions in amputated or severely nerve-injured patients. These devices use neural interfaces to record and stimulate nerve action potentials, creating a bidirectional connection with the nervous system. Most neural interfaces are based on standard metal microelectrodes.

Researchers at the Autonomous University of Barcelona (UAB) and ICN2 have demonstrated in animal models how Engineered Graphene for Neural Interface (EGNITE), a derivative of graphene, allows the creation of smaller electrodes, which can interact more selectively with the nerves they stimulate, thus improving the efficacy of the prostheses. The study also demonstrated that EGNITE is biocompatible, showing that its implantation is safe.

Researchers develop a scalable method to reduce the contact resistance of graphene

The exceptional electronic properties of graphene make it a material with large potential for low-power, high-frequency electronics. However, the performance of a graphene-based device depends not only on the properties of the graphene itself, but also on the quality of its metal contacts. The lack of effective and manufacturable approaches to establish good ohmic contacts to a graphene sheet is one of the factors that currently limit the full application potential of graphene technology. The quality of the graphene-metal contacts is described in terms of the contact resistance (RC). Low RC values are crucial for any high-frequency or low-power application. Graphene’s low density of states near the charge neutrality point (Dirac point) limits carrier injection from metals, often resulting in high RC values.

Recently, researchers from RWTH Aachen University and AMO have developed a scalable method based on laser irradiation of graphene to reduce the RC in nickel-contacted devices. A laser with a wavelength of l = 532 nm is used to induce defects at the contact regions, which are monitored in situ using micro-Raman spectroscopy.
