Facile construction of porous epoxy resin/geopolymer composites using red mud and slag by well‐distributed dual‐blending

open access: yesInternational Journal of Applied Ceramic Technology, Volume 21, Issue 6, Page 3967-3980, November/December 2024.
Porous epoxy resin/geopolymer composites by well‐distributed dual‐blending were prepared using direct foaming method with the aim of achieving high value‐added utilization of industrial by‐products. Abstract Porous geopolymer composite (E51) reinforced by E51 epoxy resin was prepared by well‐distributed dual‐blending using red mud, metakaolin, and slag

Hypernova Nucleosynthesis and Implications for Cosmic Chemical Evolution [PDF]

open access: yes, 2001
We examine the characteristics of nucleosynthesis in 'hypernovae', i.e., supernovae with very large explosion energies ($\gsim 10^{52}$ ergs). Implications for the cosmic chemical evolution and the abundances in M82 are discussed.Comment: To appear in ...

Comparison of selected cytomorphological features of canine pemphigus foliaceus and superficial pyoderma

open access: yesVeterinary Dermatology, Volume 35, Issue 5, Page 524-535, October 2024.
Background – Cytological detection of acantholytic keratinocytes (acantholytic cells [AC]) helps to identify canine pemphigus foliaceus (cPF) yet AC also occurs in superficial pyoderma (SP), the main differential diagnosis. Hypothesis/Objectives – To compare selected cytomorphological features of cPF and SP and to establish cytological diagnostic ...
