Accessing the potentially habitable subsurface waters of Ocean Worlds requires a robotic ice probe (or “cryobot”) to traverse tens of kilometers of ice with temperatures ranging from ∼100 to 273 K. Designing and planning such a mission requires

Soft landing on a plasma-treated metal surface of multiply protonated protein ions from the gas phase results in a substantial retention of protein function, as demonstrated for trypsin and streptavidin. The majority of trypsin ions soft-landed at hy

Soft landing of singly charged gas-phase ions on dry metal surfaces that were pretreated in situ by oxygen plasma results in 0.1-2% total yields of recovered intact compounds. Lysine, peptides, crystal violet dye, and a biotin conjugate are found to

A novel dry process for immobilization of hyaluronan on stainless steel surfaces is presented. This process that we call reactive landing is based on an interaction of hyperthermal gas-phase hyaluronan ions with plasma-cleaned and activated stainless

New EXAFS data at 80 K obtained on deoxyhemerythrin in solution reveal an iron-peak at a separation of 3.13 +/- 0.03 angstrom. A repeat of measurements at 300 K shows the iron-iron peak greatly reduced, confirming the hyopthesis of increased relative

Hemerythrin is a respiratory protein in several phyla of marine invertebrates. The active site of the protein contains a binuclear iron center which cycles from the ferrous to the ferric state upon oxygen binding, with a concomitant reduction of oxyg
