Programmable Pneumatic Actuator System for a Bioinspired Artificial Colon

open access: yesAdvanced Materials Technologies, EarlyView.
A modular soft robotic colon simulator driven by programmable pneumatic actuation is developed to mimic physiological and pathological‐like motility patterns of the large intestine. Finite element–guided design and distributed control enable anatomically realistic deformation for peristalsis, segmentation, and mass movements, supporting capsule ...

Integrating reverse logistics and eco-design: a proposal for a new framework

open access: yesGEPROS: Gestão da Produção, Operações e Sistemas, 2014
The concepts of Reverse Logistics and Eco-design are discussed in this paper, suggesting that these applications are often treated differently, thus not being able to achieve a higher performance in relation to environmental sustainability. The reason is

A Cryopreservation‐Based Supply Chain Strategy for Extrusion Bioprinting in Space

open access: yesAdvanced Materials Technologies, EarlyView.
Extrusion bioprinting on crewed space platforms requires a bioink that stays functional along the logistic chain. Here, cells and biomaterial ink travel separately, the cells cryopreserved and the ink cold stored, and are combined only minutes before printing.

An Analysis of Stochastic Inventory Control Models in Reverse Logistics Systems Based on a Periodic Review [PDF]

open access: yes, 2010
In reverse logistics systems demand can be partially satisfied with new items manufacture or procurement and re-turned products value recovery. The products are brought back to the places where they are stored in most models presented in literature on

A U‐shaped Microfluidic Platform for Culturing Vascularized Colorectal Cancer Spheroids Reveals Tumor–Endothelial Crosstalk and Invasion‐Associated Remodeling

open access: yesAdvanced Materials Technologies, EarlyView.
A closed U‐shaped microfluidic platform symmetrically embeds a single, size‐controlled HT29 colorectal cancer spheroid within a GFP‐HUVEC‐laden fibrin matrix. HT29 spheroids are associated with hyper‐branched endothelial network remodeling, while vascularized co‐culture is accompanied by anisotropic protrusive growth and EMT‐like marker changes in the ...

Aerosol Jet Printing of Benzocyclobutene as a Thermally Stable, Low‐Loss Dielectric for Multilayer Microwave Electronics

open access: yesAdvanced Materials Technologies, EarlyView.
Multilayer aerosol jet printed components with a low‐loss, thermally stable dielectric are demonstrated using benzocyclobutene. Ink formulation and in‐line droplet evaporation control support high‐quality, versatile, and stable printing performance. A specialized measurement for low‐loss materials reveals promising microwave properties, which, combined
