TL;DR: In this paper, the dependence of hydrogen flux and substrate temperature during implantation on the smart-cut process in GaAs have been investigated by ion beam analysis, and it was found that both the flux and the implant temperature are significant for the smart cut process.
Abstract: The dependence of hydrogen flux and substrate temperature during implantation on the smart-cutprocess in GaAs have been investigated in this paper. The lattice disorder in the samples was studied by ion beam analysis. It was found that both the flux and the implant temperature are significant for the smart-cut process. As the flux increases, the degree of exfoliation and the mean blister size increases, while the number density of blisters falls, indicating that blister evo- lution is enhanced at high dose rates.

TL;DR: Clinically, prurigo-like nodules and keloidiform plaques, tense blisters and tight atrophic scars were disseminated in the occipitals, on the trunk and on the extremities, and among several trials of treatment, only azathioprine (Imurek) seemed effective.
Abstract: 1. A case of the very rare "disseminated cicatricial pemphigoid" is presented in a 68-year-old man. Clinically, prurigo-like nodules and keloidiform plaques, tense blisters and tight atrophic scars were disseminated in the occipital region, on the trunk and on the extremities. The mucous membranes were never affected. 2. Histologically, subepidermal blisters were found. The blister roof contained the complete, intact epidermis; in the floor of the blisters, fibroplasia, angioplasia, and a scarce inflammatory infiltrate containing some eosinophils were present. 3. Direct immunofluorescence revealed linear precipitates of IgM and C3 in the basement membrane. Circulating antibodies have not been found. 4. Semithin sections and electron microscopy showed subepidermal microvesicles and fibrin deposits in initial lesion, followed by edema and blister formation within and below the fibrin deposits. 5. Among several trials of treatment, only azathioprine (Imurek) seemed effective.

TL;DR: The volume of the blister created during the laser processing, determined through volume measurements of AFM and cross-sectional SEM data, is ∼0.3 μm3 for ion doses from 7.5 × 1012 to 3.0 × 1013 ions/cm2 as mentioned in this paper.
Abstract: Compressive SiO2 films on Si substrates irradiated with sub-nanosecond laser pulses at fluences above 0.65 J/cm2 delaminate from the substrate. The volume of the blister created during the laser processing, determined through volume measurements of AFM and cross-sectional SEM data, is ∼0.1 μ3. Ion bombardment of the film prior to laser processing enhances the delamination, permitting the creation of blisters with volumes on the order of 0.3 μm3 for ion doses from 7.5 × 1012 to 3.0 × 1013 ions/cm2.

TL;DR: Clinical, immunological, histological and ultrastructural studies provided a diagnosis of mechanical dermatitis produced by microtrauma, and electron microscopy studies revealed the sub‐epidermal nature of the blisters and the presence of underlying fibrin deposits.
Abstract: We present the case of an 11-month-old baby with a burn that healed normally over a month, but subsequently developed successive crops of blisters over the scar. There were no changes in his general condition. Clinical, immunological, histological and ultrastructural studies provided a diagnosis of mechanical dermatitis produced by microtrauma. Electron microscopy studies revealed the sub-epidermal nature of the blisters and the presence of underlying fibrin deposits.
