When performing X-ray diffraction (XRD) analysis of small powder sample volumes with the Bragg-Brentano setup, choosing an appropriate sample preparation method is important. This work provides practical information on the conventional top dusted sample preparation method and the top dusted adhesive tape sample preparation method. In the latter, the powder of interest is dusted onto an adhesive tape. Because adhesive tapes contribute to the measured XRD signal as background noise, care must be taken when using a particular adhesive tape. This work assists XRD users in selecting the most suitable adhesive tape for their purpose by providing the diffractograms (Cu α radiation) of 13 commercially available adhesive tapes used for office and packing applications. In general, tapes with a matte acetate or polyvinyl chloride backing are recommended as they cause a comparatively low background signal without high-intensity reflections.

Objective: Therefore, this study aimed to evaluate the maximum displacement resistance of silicone samples adhered to human skin using different adhesives. For this purpose, colorless silicone samples (A-4530-HCRA Silicone Gum HCR) pigmented with Functional Intrinsic II Silicone Coloring System were made and distributed into five groups (1.

Background: Medical adhesives are potentially harmful to the skin, depending on the patient's condition, the adhesive agent and the adhesive application and removal technique.
Aim: The objective of the study was to determine the incidence, characteristics and influencing factors of medical adhesive-related skin injury from the indwelling urinary catheter attachment in critically ill patients.
Study Design: This is a longitudinal study.

Background: Dip-coating is a simple and cost-effective technique for synthesizing thin film sorptive phases in microextraction. The success of the coating (amount and homogeneity) relies dramatically on the wettability of the substrate, thus making the covering of smooth-surface substrates challenging. In these cases, prior to the slurry (particles and binder) deposition, the smooth-surface substrate typically requires an aggressive etching step (e.

Epidermal graft produced by suction is useful in treating vitiligo. However, it is very difficult to handle thin, flimsy, and translucent epidermis due to its in-curling and wrinkling properties. This is due to the hemispherical blister roof surface area which is twice its circular base.

Reversible protonic ceramic cells (R-PCCs) hold significant promise for energy storage and conversion. However, achieving high-performance, large-scale cells remains challenging, primarily due to issues with compatibility and adhesion at the electrode-electrolyte interface. Here, a scalable strategy is presented for regulating an active interface structure (AIS) via tape casting to develop high-performance, durable R-PCCs.
