Self-sustained biphasic catalytic particle turbulence | Nature Communications
Adding a little hydrofluoroether (HFE) organic solvent to a water based turbulent heater exchanger ups heat transfer 5x because the bubbling action assisted by the HFE pulls new cold liquid to the heat exchanger surface

Some sort of wizardry allows new highly spare arrays for RF power beaming, for medium ranges (looking at 1000km or less), which causes beam refocusing. All solid state, looking at 915MHz UHF.

Hundred-fold enhancement in far-field radiative heat transfer over the blackbody limit | Nature
So when the gap between surfaces is 25nm, you can get much higher radiative heat transfer. But if you are that close, why not go conductive?

Icon Polymer
Interesting new hose for probe&drogue aerial refueling systems, which allows power and data transfer at the drogue end unit via a clamping device, as well as telemetry of the end unit, which would be helpful for positioning. An interesting possibility is data transfer from surveillance as their current data collection is starting to exceed reasonable radio transmission capabilities. So, instead of waiting until a UAV returns to the ground to offload data, a UAV could offload data to a command tanker aircraft in theater.

Bonding-induced thermal conductance enhancement at inorganic heterointerfaces using nanomolecular monolayers : Nature Materials : Nature Publishing Group
Basically a form of phonon impedance fuzzing, by sticking an intermediate material (the nanolayer monolayer) that has intermediate phonon properties, to allow transmission of the phonon across the change in materials, when they would otherwise be reflected back at the materials interface. The short form is improved heat transfer from silicon CPU's to copper heatsinks, assuming you can get the thermal interface layer right. Not for amateurs.

Near composite piping suitable for low temperature heat exchanger evaporators for desalination.
