Abstract: A heat transfer module can include an envelope sealed to define an internal volume that contains a working fluid and a wick disposed on an internal surface of the envelope. The wick and envelope each has a first portion extending through an evaporator region and a second portion extending through adiabatic and condenser regions. The first portion of the wick is a metal hydride. The first portion of the envelope includes a metal liner surrounding the first portion of the wick, a first diffusion barrier layer disposed between the first portion of the wick and the metal liner, and a ceramic matrix composite cladding surrounding the metal liner. The second portions of the wick and envelope each includes a refractory metal and/or stainless steel.

Abstract: Provided herein is a neutron moderation module and a thermal-neutron nuclear micro-reactor.

Abstract: A gas enclosure can include a refractory metal liner; a ceramic matrix composite cladding; and a diffusion barrier layer. The refractory metal liner is adapted to surround and enclose a gas to be contained within the gas enclosure. The diffusion barrier layer is disposed between the refractory metal liner and the ceramic matrix composite cladding.

Abstract: A method of assembling a semiconductor component includes providing a pedestal, placing a first piece on the curved pedestal, wherein the first piece comprises a semiconductor die, placing a second piece over the first piece, and providing an adhesive between the first piece and the second piece. The method further includes applying pressure with a first plate to the first piece and second piece to snap the first piece with the second piece, and applying heat with a second plate to reflow the adhesive, wherein applying heat is performed simultaneously with applying pressure.
