Journal ArticleDOI
Directing stem cell fate on hydrogel substrates by controlling cell geometry, matrix mechanics and adhesion ligand composition.
TL;DR: A microengineering strategy to vary single cell geometry and the composition of adhesion ligands - on substrates that approximate the mechanical properties of soft tissues - to study adipogenesis and neurogenesis in adherent mesenchymal stem cells is demonstrated.
Journal ArticleDOI
Hysteresis behavior of electrical resistance in Pd thin films during the process of absorption and desorption of hydrogen gas
TL;DR: In this article, a novel hydrogen sensor that utilizes the electrical resistance changes in the palladium thin films with nanometer thicknesses is presented, where the sensing mechanism is based on transitory absorption of hydrogen atoms into the Pd layer, which leads to reversible alteration of the electrical resistances.
Journal ArticleDOI
Interfacial geometry dictates cancer cell tumorigenicity
TL;DR: This work shows that geometric features at the perimeter of tumour tissue will prime a population of cells with a stem-cell-like phenotype, and suggests that interfacial geometry triggers a general mechanism for the regulation of cancer-cell state.
Journal ArticleDOI

TL;DR: Currently existing 3D printing techniques and their applications in developing metallic medical implants and devices and Perspective about the current challenges and future directions for development of this technology is presented.
Journal ArticleDOI
Low-Dimensional Palladium Nanostructures for Fast and Reliable Hydrogen Gas Detection
TL;DR: The finite size effects, relative strengths and weaknesses of the respective Pd nanostructures are discussed in terms of performance, manufacturability, and practical applicability.
