Intensive investigations have been drawn on nanoscale ferroelectrics for their prospective applications such as developing memory devices. In contrast with the commonly used electrical means to process (i.e., read, write or erase) the information carried by ferroelectric domains, at present, mechanisms of non-electrical processing ferroelectric domains are relatively lacking. Here we make a sys...
The extracellular matrix proteins tenascin and fibronectin experience significant mechanical forces in vivo. Both contain a number of tandem repeating homologous fibronectin type III (fnIII) domains, and atomic force microscopy experiments have demonstrated that the mechanical strength of these domains can vary significantly. Previous work has shown that mutations in the core of an fnIII domain...
Analytical tools and processes are being developed at NASA Marshal Space Flight Center in support of the Advanced Mirror Technology Development (AMTD) project. One facet of optical performance is mechanical stability with respect to structural dynamics. Pertinent parameters are: (1) the spacecraft structural design, (2) the mechanical disturbances on-board the spacecraft (sources of vibratory/t...
The possibility of using tree prunings residues from four wood species grown in Saudi Arabia to create cementbonded particleboards (CBPs) was studied. The properties of the produced CBPs at different board densities were evaluated. Panels were made using three different board densities (1100, 1200 and 1300 kg/m) at a constant wood/cement ratio (1/2 by weight). The mechanical properties and dime...
