TL;DR: A case study reported that the use of Burnaid Gel in the treatment of fracture blisters was able to reduce the time the patient waited to receive appropriate surgical treatment, and the patient found the gel soothing to the broken skin and pleasant-smelling.
Abstract: Fracture blisters refer to a fracture complicated by overlaying blisters. Fracture blisters can occur in any orthopaedic patient who has sustained a traumatic injury, and usually arise within 24-48 hours of acute injury. Fracture blisters in the pre-operative period can lead to serious complications such as delayed wound healing, wound infection, delayed surgery and, ultimately, will prolong recovery [1]. Previous pre-operative protocol for the treatment of fracture blisters at Prince of Wales Hospital (POWH) involved manually de-roofing the blisters and applying silver sulphur diazine (SSD) cream daily with a non-adherent dressing. This method meant a delay for surgical intervention by 18-21 days [2], until the blister had healed, thereby reducing the risk of infection during the operative and post-operative phase. Burnaid Gel TM (Woundaid Hydrogel) is a propylene glycol gel with >90% purified water and an active ingredient of 4% melaleuca oil (teatree oil - TTO) [3]. A case study reported that the use of Burnaid Gel in the treatment of fracture blisters was able to reduce the time the patient waited to receive appropriate surgical treatment. The patient found the gel soothing to the broken skin and pleasant-smelling. It was also noted that the gel did not cause any irritation or maceration to the healthy outerlying skin.

TL;DR: In this article, four groups of He + and H + with different dose combinations are implanted into GaAs crystal, and different phenomena of blisters and exfoliation appear on the surface.
Abstract: Four groups of He + and H + with different dose combinations are implanted into GaAs crystal. After annealing, different phenomena of blisters and exfoliation appear on the surface. High resolution X-ray diffraction (HRXRD) is used to irradiate the surfaces of the four samples, and the diffraction satellite peaks are observed to move to the lower angles. The surface morphology of the four samples after annealing is observed by optical microscope. The depth of craters and the height of blisters are measured by atomic force microscope (AFM), and the critical pressure and internal stress of blisters are calculated. The damage microstructure induced by ion implantation after annealing is observed by transmission electron microscope (TEM), and the stress intensity factor at the crack tip is calculated. The different mechanisms of He + and H + in GaAs single crystal are compared. The dose combination of He + and H + is optimized to explore a more cost-effective way for GaAs film exfoliation.

TL;DR: In this article, the authors proposed a method to prevent the generation of blisters and peeling in the alloy contg. a specified amt. of Ni, in which the content of C is regulated to = 2.0 Mn/Si, 0.003 to 0.010% C, <=0.003% S and ≤ 5ppm Se.
Abstract: PURPOSE:To prevent the generation of blisters and peeling in the alloy contg. a specified amt. of Ni, in which the content of C is regulated to =2.0 Mn/Si, 0.003 to 0.010% C, <=0.003% S and <=5ppm Se. In the alloy, in the case of <2.0 Mn/Si ratio, SiO2 in the molten metal increases and high m.p. hard SiO2-MnO-Al2O3 series nonmetallic inclusions remain in the ingot. In the case of <0.003% C, nonmetallic inclusions increase. Since S forms the nonmetallic inclusions of MnS, the upper limit is regulated to 0.003. Since even a small amt. of Se forms hard MnSe series nonmetallic inclusions to cause blisters and peeling, its upper limit is regulated to 5ppm.

TL;DR: A manually operable tool and method of using the tool to open blisters on a blister pack is described in this paper, which involves the step of laterally sliding a laterally aligned blister pack through the guideway and out through the second end, whereby the cutting edge contacts and cuts through an end of the blisters slid past the cutting edges without cutting completely through the blister pack.
Abstract: A manually operable tool and method of using the tool to open blisters on a blister pack The tool includes a body defining a laterally extending guideway of b-shaped cross-section, and a sharp with a laterally extending cutting edge which extends transversely into the guideway from a sidewall without contacting the opposite sidewall, thereby leaving a transverse gap between the sharp and the second sidewall The method involves the step of laterally sliding a laterally aligned blister pack through the guideway and out through the second end, whereby the cutting edge contacts and cuts through an end of the blisters slid past the cutting edge without cutting completely through the blister pack

TL;DR: It is demonstrated that confinement in GQB persists even in the presence of a variation in the inter-layer coupling, and the energy levels in G QB exhibit electron-hole symmetry that is sensitive to the electrostatic bias.
Abstract: Bilayer graphene samples may exhibit regions where the two layers are locally delaminated forming a so-called quantum blister in the graphene sheet. Electron and hole states can be confined in this graphene quantum blisters (GQB) by applying a global electrostatic bias. We scrutinize the electronic properties of these confined states under the variation of interlayer bias, coupling, and blister's size. The spectra display strong anti-crossings due to the coupling of the confined states on upper and lower layers inside the blister. These spectra are layer localized where the respective confined states reside on either layer or equally distributed. For finite angular momentum, this layer localization can be at the edge of the blister and corresponds to degenerate modes of opposite momenta. Furthermore, the energy levels in GQB exhibit electron-hole symmetry that is sensitive to the electrostatic bias. Finally, we demonstrate that confinement in GQB persists even in the presence of a variation in the inter-layer coupling.
