TL;DR: A giant oily blister appears at the centripetal end where the oil drops were stratified but normal blisters appear in the other region when the centrifuged eggs are immersed in zinc chloride.
Abstract: (1) Blister formation occurs when eggs ofCoccophora Langsdorfii, Fucus evanescens, andSargassum confusum are immersed in zinc chloride solution at a density higher than 25 per cent. (2) When the egg is stained vitally with brilliant green, neutral red, or with toluidin blue, then immersed in zinc chloride, coloured blisters appear, and their colour is the same as that of the stained egg. (3) A giant oily blister appears at the centripetal end where the oil drops were stratified but normal blisters appear in the other region, when the centrifuged eggs are immersed in zinc chloride. (4) Normally, the blister, seems to be the extrusion of the hyaline plasm through small holes of the plasma membrane made by zinc chloride.

TL;DR: The case of a 64-year-old-female who presented with a recurrent manifestation of well-defined oral blood-filled blisters which ruptured and healed spontaneously is presented to bring awareness and avoid unnecessary investigations and misdiagnosis.
Abstract: Angina bullosa hemorrhagica (ABH) is a condition of the oral mucous membrane, characterized by the sudden appearance of blood-filled blister(s) within the oral cavity. In the majority of cases, these blisters occur on the oropharynx or palate. The blisters usually rupture in a day or two and heal spontaneously without any further scarring or discomfort. In rare cases, if a large lesion located in the throat does not rupture spontaneously, it may lead to airway obstruction. We present the case of a 64-year-old-female who presented with a recurrent manifestation of well-defined oral blood-filled blisters which ruptured and healed spontaneously. There were no identifiable risk factors. Angina bullosa hemorrhagica was diagnosed clinically. The main objective of this case report is to bring awareness and avoid unnecessary investigations and misdiagnosis.

TL;DR: In this paper, the effects of 3 MeV Fe11+ ions pre-damage on blistering and deuterium (D) retention in two types of tungsten, polycrystalline hotrolled bulk Tungsten (W) and recrystallized tengsten (rec-W) exposed to D plasma have been investigated.
Abstract: The effects of 3 MeV Fe11+ ions pre-damage on blistering and deuterium (D) retention in two types of tungsten, polycrystalline hot-rolled bulk tungsten (W) and recrystallized tungsten (rec-W) exposed to D plasma have been investigated. Two kinds of blisters can be distinguished at the surface of undamaged W. One is intra-granular blisters with the size of ~0.2–1.5 μm, and the other is inter-granular blisters with the size of ~15–22 μm. Only intra-granular blisters are observed at the surface of undamaged rec-W. Compared to the undamaged W, the size of blisters in the damaged W increases, while the density of blisters decreases. However, there are no blisters at the surface of damaged rec-W. For both W and rec-W, Fe11+ ions pre-damage can effectively inhibit the formation of intra-granular blisters. The grain boundaries close and parallel to the sample surface play an important role for the formation of inter-granular blisters. Fe11+ ions irradiation introduces a large number of defects such as dislocation loops and nano-scale voids in W and rec-W samples. The total D retention in W and rec-W increases significantly due to the Fe11+ ions irradiation and tends to be saturated at around 0.3 dpa. In contrast, the total D retention in the undamaged W is higher than that in the undamaged rec-W, but it is quite comparable in the damaged W and rec-W samples.

TL;DR: In this article , the acceleration effects of typical degradation methods in non-defective vinyl ester resin organic coatings containing glass flakes such as high-temperature immersion and immersion in chemical accelerators are clarified using physiochemical techniques.
Abstract: Organic coatings are applied as a corrosion prevention measure, but their effectiveness may degrade over time. In this study, the acceleration effects of typical degradation methods in non-defective vinyl ester resin organic coatings containing glass flakes such as high-temperature immersion and immersion in chemical accelerators are clarified using physiochemical techniques. Immersion in an acetic acid (AcOH) aqueous solution causes resin swelling, and the behaviors are quantitatively evaluated through gravimetric, thickness, and electrochemical impedance spectroscopy (EIS) measurements. Furthermore, a combined process of immersion in hydrofluoric acid and an AcOH aqueous solution reduces the electrical properties and eventually blisters the thick coating surface. This result suggests that an appropriate combination of the resin swelling and the glass degradation (glass dissolution and/or formation of the gap between glass and resin) decrease mechanical properties of the glass flake coating and causes blisters. In order to help the health diagnosis of the visually non-defective aged glass flake coating, the relationship between the electrical characteristic values and the invisible degradation by accelerated tests is finally indicated.

TL;DR: Wang et al. as discussed by the authors studied surface blistering morphologies of W thin films irradiated by 30-keV He ion beam and found that the blistering morphology strongly depends on He fluence.
Abstract: Surface blistering morphologies of W thin films irradiated by 30 keV He ion beam were studied quantitatively. It was found that the blistering morphology strongly depends on He fluence. For lower He fluence, the accumulation and growth of He bubbles induce the intrinsic surface blisters with mono-modal size distribution feature. When the He fluence is higher, the film surface morphology exhibits a multi-scale property, including two kinds of surface blisters with different characteristic sizes. In addition to the intrinsic He blisters, film/substrate interface delamination also induces large-sized surface blisters. A strategy based on wavelet transform approach was proposed to distinguish and extract the multi-scale surface blistering morphologies. Then the density, the lateral size and the height of these different blisters were estimated quantitatively, and the effect of He fluence on these geometrical parameters was investigated. Our method could provide a potential tool to describe the irradiation induced surface damage morphology with a multi-scale property.
