TL;DR: In this paper, 16 metals implanted to saturation with 300-keV N2+ ions have been studied using nuclear resonance broadening and Rutherford backscattering techniques to profile the implanted concentration.
Abstract: Sixteen metals implanted to saturation with 300‐keV N2+ ions have been studied using nuclear resonance broadening and Rutherford backscattering techniques to profile the implanted concentration. Blisters due to the implanted nitrogen were observed in Mg, Al, Ti, V, Cr, Nb, Mo, Ta, W, and AISI 304 steel but not in Cu, Zr, Ag, Hf, and Au. The nominal saturation concentration at maximum varied from 50 to 60 at. % for all cases except for Cu, Ag, and Au, where it was 20 at. %. The surface hardness was generally increased by a factor between 1.2 and 2.3. However, no increase was observed for Mo, Ag, and Au. The mononitride formation in Ti, Zr, and Hf was verified by x‐ray diffraction. The formation of blisters and diffusion in the preparation of nitrides is discussed.

TL;DR: Repetitive frictional insults over years to human skin result in lichenification, callosites, and clavi (corns).
Abstract: Repetitive frictional insults over years to human skin result in lichenification, callosites, and clavi (corns). No measurements of the forces involved have been made for callosites or corns. Two reports deal with lichenification produced by repeated rubbing over weeks. By contrast, friction blisters have been seriously studied because they can be produced in minutes and because foot blisters can disable soldiers. Three devices to measure the coefficient of friction of materials on man's skin and eight machines to rub man's skin are reviewed.

TL;DR: In this paper, the time required to grow hydride blisters was estimated from the blister size and the hydrogen distribution in its neighborhood, by using simple equations derived from thermal diffusion theory.

TL;DR: Although skin involvement as a result of CO poisoning is less frequently reported today than in the past (perhaps because of misidentified burns or because of more aggressive resuscitation and treatment protocols), the physician should recognize that such blisters may signal severe CO poisoning.

TL;DR: The histology of blisters induced in rats using dry-ice or vacuum applied to the hind limb footpad has been examined by light microscopy and indirect fluorescence immunohistochemistry for substance P like immunoreactivity to help study neurogenic inflammation.
Abstract: The histology of blisters induced in rats using dry-ice or vacuum applied to the hind limb footpad has been examined by light microscopy and indirect fluorescence immunohistochemistry for substance P like immunoreactivity. The effects of sciatic nerve stimulation on plasma extravasation as determined by estimation of Evans Blue content of blister fluid has been examined. Plasma extravasation occurs in both blister types following nerve stimulation. Plasma extravasation may be induced by substance P released from nerve terminals in the blister wall. Vacuum induced blisters have less tissue and nerve damage and therefore less of an inflammatory response, but plasma extravasation is greater in thermal blisters. Blisters serve as a useful model for the study of neurogenic inflammation.

TL;DR: In this article, the elastic modulus calculated from the crack length is far below the shear modulus C 44 of unirradiated pyrolytic graphite, which implies that these cracks and blisters correspond to the grain boundaries and etch pits, respectively.
