Replacing 3D printing plastics with plant-derived materials

Replace 3D printing plastics

USDA grant to fund Penn State researchers developing new and sustainable materials from lignocellulosic biomass

 

A sustainable resin material comprising agriculturally derived components could potentially replace plastics used in large-format 3D printing, which can produce furniture, boats and other similarly sized objects, according to a team of Penn State agricultural and biological engineers.

Novel hydrogel finds new aptamers, or ‘chemical antibodies,’ in days

One double-helix strand of DNA could extend six feet, but it is so tightly coiled that it packs an entire sequence of nucleotides into the tiny nucleus of a cell. If that same DNA was instead split into two strands and divided into many, many short pieces, it would become trillions of uniquely folded 3D molecular structures, capable of bonding to and possibly manipulating specifically shaped molecules — if they’re the perfect fit.

Can AI crave a favorite food?

AI Sensor for Taste Image

'Electronic tongue' holds promise as possible first step to artificial emotional intelligence

Can artificial intelligence (AI) get hungry? Develop a taste for certain foods? Not yet, but a team of Penn State researchers is developing a novel electronic tongue that mimics how taste influences what we eat based on both needs and wants, providing a possible blueprint for AI that processes information more like a human being.  

New wearable sensor makes continuous analysis of sweat possible, researchers say

Continuous monitoring of sweat can reveal valuable information about human health, such as the body’s glucose levels. However, wearable sensors previously developed for this purpose have been lacking, unable to withstand the rigors or achieve the specificity needed for continuous monitoring, according to Penn State researchers. Now, the research team has created a novel wearable patch that may be up to the task.

Fellowship gives undergraduates chance to do research with real impact

By Jamie Oberdick

UNIVERSITY PARK, Pa. — One of the more innovative energy-saving tools at Penn State was not implemented by a faculty member, employee, or graduate student. Instead, it was developed by undergraduate students who are part of an innovative and unique research fellowship offered by the Materials Research Institute (MRI).
