Advanced Healthcare Materials, EarlyView.Engineered microparticle topographies direct human mesenchymal stem cell osteogenesis without biochemical additives. This osteogenic commitment is driven by canonical Hedgehog signaling and followed by temporal IGF‐II engagement. Two‐photon polymerization demonstrates spatial control, enabling the engineering of topographical gradients that pattern ...

Advanced Healthcare Materials, EarlyView.A multilayered small‐caliber vascular scaffold combining electrospinning and 4‐axis printing is developed and biofunctionalized with marine sulfated polysaccharides from Holothuria tubulosa. The resulting construct exhibits enhanced hemocompatibility, tunable mechanical properties, and supports endothelial and smooth muscle cell adhesion and ...

Half/Full Toroidal, Single/Double Roller, CVT Based Transmission for a Super-Turbo-Charger [PDF]
, 2019 Turbocharging dramatically improves the power density of internal combustion engines. However, when the energy to turbine is either smaller or larger than what is needed by the compressor for a specific steady state or transient point, there are ...

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction
Advanced Healthcare Materials, EarlyView.Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...

Strain-based fatigue analysis of wheelchairs on a double roller fatigue machine.
Journal of rehabilitation research and development, 1996 Results are presented from an experimental program that recorded the outputs of strain gages mounted on two wheelchair frames (one manual, one power) as the wheelchairs were run on a double roller fatigue machine. Rectangular strain gage rosettes were attached to the frames near the cross tube center pin and on the side frame behind a front caster ...

Thermal Processing Creates Water‐Stable PEDOT:PSS Films for Bioelectronics
Advanced Materials, Volume 37, Issue 13, April 2, 2025.Instead of using chemical cross–linkers, it is shown that PEDOT:PSS thin films for bioelectronics become water‐stable after a simple heat treatment. The heat treatment is compatible with a range of rigid and elastomeric substrates and films are stable in vivo for >20 days.
