I would look at SST International and Sikama International. You might solder using forming gas. Forming gas is 10% hydrogen and 90% nitrogen or 8% hydrogen and 92% nitrogen. Chris

We have been using nitrogen in our reflow ovens for many years to reduce oxidation on our solder joints. Management is concerned about the high cost of nitrogen and have suggested we use hydrogen instead. I'm not sure if this is a good idea, but we

Therefore, hydrogen energy will never be cool. Even if electric vehicles are not competitive at present, they will not be as popular as electric vehicles in the future. It will still be an important part of new energy vehicles. The current development areas of hydrogen energy and pure electricity are different. Pure electricity for passenger cars and hydrogen for commercial vehicles.

Silicon is arguably the best electronic material, but it is not a good optoelectronic material. By employing first-principles calculations and the cluster-expansion approach, we discover that hydrogenated bilayer silicene (BS) shows promising potential as a new kind of optoelectronic material. Most significantly, hydrogenation converts the intrinsic BS, a strongly indirect semiconductor, into a direct-gap semiconductor with a widely tunable band gap. At low hydrogen concentrations, four ground states of single- and double sided hydrogenated BS are characterized by dipole-allowed direct (or quasidirect) band gaps in the desirable range from 1 to 1.5 eV, suitable for solar applications. At high hydrogen concentrations, three well-ordered double-sided hydrogenated BS structures exhibit direct (or quasidirect) band gaps in the color range of red, green, and blue, affording white light-emitting diodes. Our findings open opportunities to search for new silicon-based light-absorption and light-emitting materials for earth-abundant, high efficiency, optoelectronic applications.Originally published by the American Physical Society

We demonstrate the viability of using ultra-thin sheets of microbially grown nanocellulose to build functional medical sensors. Microbially grown nanocellulose is an interesting alternative to plastics, as it is hydrophilic, biocompatible, porous, and hydrogen bonding, thereby allowing the potential development of new application routes.
