An Accessible Microfluidic Platform for the Generation of Polarized Brain Organoids
Advanced Materials Technologies, EarlyView.This study presents an accessible double‐gradient microfluidic device that enables controlled morphogen delivery and spatially polarized differentiation in brain organoids. By integrating a pump‐free design and stable fabrication method, the platform generates dorsal–ventral neuronal asymmetry, offering a reproducible and versatile approach to model ...

Fire Resistance of Unprotected Steel Columns
Journal of the Structural Division, 1973 Fully developed building fires generally attain gas temperatures in the order of 2000 degrees Fahrenheit. As the mechanical properties of steel deteriorate rapidly at temperatures of about one half this magnitude, it is necessary to provide some means of keeping steel columns relatively cool during exposure to fire, with the possible exception of ...

Advanced Materials Technologies, EarlyView.We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...

Fire Resistance Tests of Various Fire Protective Coatings
Materials Science, 2011 Tests were carried out on more than 14 different samples of fire protective coatings in order to investigate a relation between the thickness of the intumescent fire protection coating and the time of exposure to heat. A number of coatings of different chemical composition enabled to determine the fire resistance behaviour patterns. During test the one-

Advanced Robotics Research, EarlyView.A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...
