Della Martin Roy

Roy left her mark in concrete

Della M. Roy, Emeritus Professor of Materials Science, was the first female materials scientist ever elected to the National Academy of Engineering (NAE,1987), the first woman from Penn State to be elected to the NAE, and the first woman elected to the World Academy of Ceramics.

An atomically resolved scanning transmission electron microscopy (STEM) image of the polar nanoregions (PNRs) embedded in the nonpolar matrix in the layered perovskite material (Ca, Sr)3Mn2O7. Bright contrast in the images can be directly interpreted as the atomic columns in the crystal. Credit: Alem Group/Jennifer M. McCann, MRI. All Rights Reserved.

A team of researchers have observed and reported for the first time the unique microstructure of a novel ferroelectric material, enabling the development of lead-free piezoelectric materials for electronics, sensors, and energy storage that are safer for human use.

Penn State researchers developed a new nanoengineered granular hydrogel bioink, used here to print an image of the Nittany Lion logo. This bioink helps to achieve previously unattained levels of porosity, shape fidelity and cell integration when 3D printing biomaterials. Credit: Provided by Amir Sheikhi. All Rights Reserved.

Penn State researcher was recognized as 'Rising Star' for the work

After soaking the materials in water (as shown in middle column), Penn State researchers chemically reacted shredded wood pulp, cotton paper and ground corncob and tomato peels to convert them into microproducts, nanoparticles and solubilized biopolymers (third column). Adding these microproducts or nanoparticles to solutions containing the rare earth element neodymium triggered the separation process, allowing for capture of the neodymium.

Penn State researchers used micro- and nanoparticles created from the organic materials to capture rare earth elements from aqueous solutions.
