Abstract Shear rheology and atomic force microscopy (AFM) are used to characterize the stiffness of hydrogels in tissue engineering applications, with several studies reporting differences orders magnitude elastic moduli determined by these two methods. This work compares properties soft fibrin polyethylene glycol (PEG) for stem cell AFM indentation different probe sizes (from nano‐ micrometer)...

In this work a W coating was deposited through PS in Ar-H2 atmosphere on substrate of CuCrZr with an interlayer consisting gradually changing fractions Cu and W. The the showed good adhesion no cracks were observed. hardness along determined by nano-indentation tests results that gradient does exist both metals. Microstructural examinations suggest depends texture, which exhibits significant di...

Since the mechanical properties of single cells together with the intercellular adhesive properties determine the macro-mechanical properties of plants, a method for evaluation of the cell elastic properties is needed to help explanation of the behavior of fruits and vegetables in handling and food processing. For this purpose, indentation of tomato mesocarp cells with an atomic force microscop...
