Nanocellulose has a variety of advantages, which make the material most suitable for use in biomedical devices such as wound dressings. The material is strong, allows for production of transparent films, provides a moist wound healing environment, and can form elastic gels with bioresponsive characteristics. In this study, we explore the application of(More)
offers the possibility of producing mass quantities of a wide variety of electronic components and devices quickly and at lower cost. Flexography is mainly used for packaging applications, but is also a potential method for the micro manufacture of electronic devices, smart packaging and RFID. Fine solid lines of high quality are essential to enable(More)
This article presents a novel method for accelerated wear of squeegees used in screen printing and describes the development of mechanical tests which allow more in-depth measurement of squeegee properties. In this study, squeegees were abraded on the screen press so that they could be used for subsequent print tests to evaluate the effect of wear on the(More)
Numerical modelling of atomic force microscopy cantilever designs and experiments is presented with the aim of exploring friction mechanisms at the microscale. As a starting point for this work, comparisons between finite element (FE) models and previously reported mathematical models for stiffness calibration of cantilevers (beam and V-shaped) are(More)
In this work, a two-dimensional numerical model for the convective drying process of ceramic shell layers was developed. The governing system of fully coupled non-linear partial differential equations describing the process was derived from a mechanistic approach along with the implementation of continuum model. The most extensive formulation of the(More)
