Hybrid copper-gold nanoparticles convert CO2

Hybrid copper-gold nanoparticles convert CO2 - Now researchers at MIT have come up with a solution that may further reduce the energy needed for copper to convert carbon dioxide, while also making the metal much more stable. Co-author Kimberly Hamad-Schifferli of MIT says the findings point to a potentially energy-efficient means of reducing carbon dioxide emissions from powerplants. A paper detailing the results will appear in the journal Chemical Communications.

Oscillating Gel Acts Like Artificial Skin, Giving Robots Potential Ability to “Feel”

Oscillating Gel Acts Like Artificial Skin, Giving Robots Potential Ability to “Feel” - Sooner than later, robots may have the ability to “feel.” A team of researchers from the University of Pittsburgh and MIT have demonstrated that a nonoscillating gel can be resuscitated in a fashion similar to a medical cardiopulmonary resuscitation. These findings pave the way for the development of a wide range of new applications that sense mechanical stimuli and respond chemically—a natural phenomenon few materials have been able to mimic.

Sponge-like spheres give RNA the armour it needs

  • Sponge-like spheres give RNA the armour it needs - MIT researchers have now come up with a novel delivery vehicle in which RNA is packed into microspheres so dense that they withstand degradation until they reach their destinations. The new system, described Feb. 26 in the journal Nature Materials, knocks down expression of specific genes as effectively as existing delivery methods, but with a much smaller dose of particles.
