Hemostatic complications associated with ventricular assist devices

open access: yesResearch and Practice in Thrombosis and Haemostasis, 2019
Hemostatic complications are common in patients with ventricular assist devices. The pathophysiologic mechanisms that lead to dysregulated hemostasis involve complex interactions between device surface, sheer stress, and blood flow. These factors lead to

Performance evaluation of a pulsatile ventricular assist device under non physiologic pumping frequencies by means FEM and 2D approach [PDF]

open access: yes, 2017
A ventricular assist device (VAD) is a blood pump that works in parallel with heart. It is used as a mechanical assistance for patients that suffer cardiac insufficiency: as a therapy, as a bridge to transplant or to extend life.

Enhancing performance during inclined loaded walking with a powered ankle-foot exoskeleton [PDF]

open access: yes, 2014
A simple ankle-foot exoskeleton that assists plantarflexion during push-off can reduce the metabolic power during walking. This suggests that walking performance during a maximal incremental exercise could be improved with an exoskeleton if the ...

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

SI‐bioATRP in Mesoporous Silica for Size‐Exclusion Driven Local Polymer Placement

open access: yesAdvanced Functional Materials, EarlyView.
An enzyme‐catalyzed surface‐initiated atom transfer radical polymerization (SI‐bioATRP) of an anionic monomer within mesoporous silica particles, using hemoglobin as a catalyst, allows for controlling the location of the formed polymer via size‐exclusion effects between the nanopores and the biomacromolecules, thereby opening routes to functional ...
