An Innovative Way to Enhance the PV Response of a Ferroelectric Material

Energy / /

Photo by Andreas Gücklhorn on Unsplash In the recent paper: “Strongly enhanced and tunable photovoltaic effect in ferroelectric-paraelectric superlattices (Jun 2021)”, researchers found a way to engineer a superlattice of ferroelectric BaTiO3 sandwiched between paraelectric SrTiO3 and CaTiO3 resulting in 1000 times higher photovoltaic (PV) effect than measured in regular BaTiO3 of a similar thickness. […]

Nano Food Additives, Good or Bad?

Food / /

Nanotechnology provides many opportunities for improvement in the food industry. These include intelligent packaging with sensors to detect when food has gone bad, longer shelf lives due to antibacterial packaging, not to mention nano food additives with various benefits. Some of these benefits are better nutrient delivery using nanoencapsulation [i], and improving flavors, texture, and

Removing Atomic Layers from Nanostructures with Thermal ALE

Nanofabrication / /

Thermal Atomic layer etching (ALE) is a recently developed technique to fabricate nanostructures with high precision. While not yet as scalable as other techniques, it shows promising application possibilities. To improve the power of integrated circuits such as CPUs, we need to build finer structures of transistors that can store the information used in electronic

Did the Romans Know Nanotechnology? Introduction to Nanotechnology

Uncategorized / /

One of the earliest known uses of nanomaterials was by the Romans to produce stained glass that changes color depending on the angle of the light source. A famous example is the Lycurgus cup, AD 300s[i], which is portrayed in The British Museum in London[ii]. The cup is a green opaque color when light is
