The Nonlinear Visco‐Hyperelastic Damage Mechanics of Individual Electrospun Polycaprolactone Fibers: Experiments and Modeling

open access: yesAdvanced Engineering Materials, EarlyView.
This study investigates the complex mechanics of individual electrospun polycaprolactone fibers under small and large strains. Combining experiments with a visco‐hyperelastic damage model, this work reveals and quantifies these fibers’ nonlinear behavior, including strain‐stiffening, viscoelasticity, and damage.

Influence of Testing Temperature on the Mechanical Performance of Brazed Conventionally and Additively Manufactured 316L Stainless Steel Joints

open access: yesAdvanced Engineering Materials, EarlyView.
This study reports for the first time the mechanical properties of brazed joints featuring Additively manufactured parts, such parts will likely need to be joined or combined with other components, and brazing offers a way of doing this for complex shapes without distortion. A new shear test methodology developed for such joints is also described.

Prototheca: A Danger Underwater

open access: yesIDCases, 2017
Prototheca wickerhamii rarely causes systemic infection in humans but when it occurs, there are coexisting comorbidities. This case illustrated shows the manifestation of this opportunistic microorganism in an immunosuppressed patient. The patient was successfully treated with Liposomal amphotericin B with complete resolution of the lesions.
