Current Research: Analysis of Ceramic Vessel Residues from the Washington Square Mound Site (41NA49) for Evidence of Peyote use by the Caddo in the 13th-15th centuries A.D. [PDF]

open access: yes, 2019
In 2012, Perttula requested permission from to the Caddo Nation of Oklahoma\u27s Repatriation Committee to analyze small samples (ca. 1-2 grams of ceramic paste, or sherds ca.

3D‐Printed Serial Snap‐Through Architectures for Programmable Mechanical Response

open access: yesAdvanced Engineering Materials, EarlyView.
A serial snap‐through architecture is realized using compact 3D‐printed von Mises truss units arranged in a staged cascade. Their geometry and boundary conditions program multistage mechanical responses with plateaux and re‐hardening regimes. An inverted‐compliance model predicts these behaviors and enables analytical design of programmable force ...

Glass-ceramics for ceramic/ceramic and ceramic/metal joining applications [PDF]

open access: yes
The use of sintered cordierite/enstatite glass-ceramics as interlayers for joining silicon\ud nitride to itself and to metals has been investigated. The role of the additives B203 and\ud P205, which control the dynamics of sintering and crystallisation, has been studied\ud using SEM, XRD and non-isothermal DTA-based measurements of activation energy ...

Ideal Molecular Sieving with a Dense MOF for Helium Upgrading with Highly Diffusion Selective Mixed Matrix Membranes

open access: yesAdvanced Functional Materials, EarlyView.
The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.
