2021-9-30 · Features The new MSort NIR sorting machine uses near-infrared technology to reliably separate bulk materials with the same visual appearance, but with different chemical composition in fractions of a second. This allows tasks to be accomplished that were beyond the limits of optical sorting, such as separation of plastics in glass recycling.
Traumatic spinal cord injury (SCI) is caused by external physical impacts and can induce complex cascade events, sometimes converging to paralysis. Existing clinical drugs to traumatic SCI have limited therapeutic efficacy because of either the poor blood–spinal cord barrier (BSCB) permeability or a single function. Here, we suggest a "pleiotropic messenger" strategy based on near ...
