Contactless steam generation and superheating under one sun illumination | Nature Communications
Okay, it's cheating to say one sun when using a concentrator, but switch from direct contact heat transfer with capillary flow to IR emitter and vapor passthru is interesting

Preparation of energy storage material derived from a used cigarette filter for a supercapacitor electrode - Abstract - Nanotechnology - IOPscience

Steam from the sun
So at 10x solar concentration, the surface cover composite sheet composed of the graphite flake thermal absorber/boiler coupled to an underlying buoyant porous carbon air foam, creates steam pretty well. I assume the insulating factor of the carbon air foam reflects more heat into the boiler region to improve efficiency, rather than letting heat travel through and warm the bulk water.

NC State News :: NC State News and Information » New Metallic Bubble Wrap Offers Big Benefits Over Other Protective Materials
Basically a very specific variant of metal foams (using large single bubbles), you can make stiff structures without a bulk material, and the bubble aspect is more controllable rather than a normal bulk foamed structure.

Apparently Toucan birds have a highly mechanically optimized beak. Very lightweight, with a hollow structure where there are no stresses, and elsewhere a bone fiber/membrane foam enclosed by an outer keratin tile sheet exterior, creating a natural biocomposite foam sandwich material in their beaks. Still doesn't explain fully why the beaks are so large, especially for a fruit eater. There was other research into beak properties by using IR camera studies, and it appears the beak is also used as a high performance controllable blood heat radiator to dump metabolic heat. They do interesting tricks like doing a burst of heat dumping just prior to going to sleep to slow down metabolic processes quicker.

ULTRAMET - Advanced Materials Solutions
Apparently involved with a new high temp noise suppression foam made from hafnium carbide/silicon carbide that ca be stuffed directly into a combustor to provide combustion noise suppression. The foam has high permeability, allowing gases and combustion to move freely, and the structure helps to create uniform combustion. Though I can't imagine this being useful for any high speed gas /liquid fuel combustors/engines, but the press releases talked about jet engines so maybe it actually can?

Radiator Graphite-Foam.pdf (application/pdf Object)
Interesting concept for using airfoil pressure differential to force air through a heat exchanger embedded in the rear third of an airfoil, while having low frontal drag area. As noted in the PDF, for vehicle applications there will still be a need for an auxiliary fan when stopped, which likely means the airfoil will still be in the engine bay or embedded in the hood to utilize the forced air fan.
