CEP: News Update


Researchers at the Univ. of Minnesota (UM) have developed a transparent, 3D-printed polymer skull that can be implanted in mice to study a wide swath of the cerebral cortex — the outer surface of the brain.

Recently, 3D printing has captured the interest of the public and the science community — and many of the innovations it has inspired have made headlines around the world. But less is known about 3D printing’s latest successor, which has been termed 4D printing.

A team of researchers at Idaho National Laboratory (INL) has developed a novel method to recover rare earth elements (REEs) from phosphogypsum, a waste product of phosphate rock mining.

Furfural is one of the world’s oldest renewable chemicals — it is derived from biomass, namely from crop residues such as corn cobs or wheat bran. It serves as a sustainable, nonpetroleum-based chemical feedstock for fuels, solvents, and polymers.

Today, much of the world’s population has tasted only the Cavendish banana, a hardy species consumed by the billions each year. In the 1950s, a deadly strain of Panama disease tore through Central and South America, almost completely destroying banana plantations ripe with the world’s banana of choice: the Gros Michel.

Quantum dots (QDs) are tiny, semiconductive nanocrystals that have gained notability over the past two decades. The nanocrystals are able to absorb energy from ultraviolet (UV) light and emit photons that can provide light and color for a variety of applications, including laser technology, biological sensing, photovoltaic cells, and light-emitting diodes (LEDs).
