Primary and Secondary Grzybowski’s Generalized Eruptive Keratoacanthoma: A New Perspective on Management, Clinical Features, and Prognosis

International Journal of Dermatology, EarlyView.
ABSTRACT Grzybowski's generalized eruptive keratoacanthoma (GEKA) is a rare variant of keratoacanthomas, characterized by hundreds to thousands of lesions, accompanied by pruritus, mucosal involvement, and comorbidities. Our aim was to analyze the clinical presentation, associated comorbidities, treatment strategies, and outcomes of GEKA.

Identification of charge carriers and quantification of diffusion coefficients in the energy landscape of S53P4 bioglass

Journal of the American Ceramic Society, EarlyView.
Dedicated ion transport experiments reveal the relevant mobile cations in the bioglass S53P4. Na+ is the only mobile charge carrier under ion‐exchange conditions at moderate electric fields. Ca++ becomes mobile under electro‐poling conditions associated with large electric fields.

Hydrogen response to high‐density dislocations in bulk perovskite oxide SrTiO3

Journal of the American Ceramic Society, EarlyView.
High‐density dislocations are engineered into single‐crystal strontium titanate using cyclic Brinell indentation scratch tests at room temperature. These dislocations are found effective in uptaking hydrogen. Abstract Hydrogen plays an increasingly important role in green energy technologies. For instance, proton‐conducting oxides with high performance
