Abstract Global concerns about climate change have led to the development of building materials that use plant biomass with added benefit sequestering carbon from atmosphere. Lightweight concrete made hemp, is a material huge potential in terms its ability achieve hygro-thermal performances close those polystyrene. This ecological material, referred literature as hemp concrete, some components ...

The wood used in making musical instruments usually undergoes pre-treatments or conditioning. Some processes have resulted from laboratory research, while many treatments are applied by craftsmen using traditional methods that have not yet been scientifically assessed. This paper is based on laboratory methods which simulate hydrothermal pre-treatments traditionally applied by Iranian lute make...

The swelling/shrinkage of spruce wood samples (Picea Abies) is documented with high resolution XRay Tomography and advanced image analysis tools. We report the reversible moisture-induced global and local deformations at the cellular and sub-cellular scales. In particular, we present sophisticated methods for detecting local deformations in the cell wall. Insight is given on the hygromechanical...

Expression and purification of recombinant proteins are fundamental techniques in molecular biology. Many different cell systems ranging from bacteria to mammalian cell lines are commonly used. One of the most widely used systems is the baculovirus expression system. An alternative for large-scale production of eukaryotic proteins are stably transfected Schneider Drosophila line 2 cells (Catalo...

Interfacial delamination is the major reliability issue of Quad Flat No-lead (QFN) packages under the JEDEC-MSL preconditioning and reflow process. Failures will occur when the hygrothermal stress exceeds the interfacial strength. Simulation based on finite element model is a popular method for studying the failure mechanism. However, the non-accurate material properties and lack of experiment ...
