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.

The prospects for neuromedicine within nanotechnology

Healthtech, Medicine / /

According to the Global Burden of Disease Study in 2017 Neurological disorders are an increasing health burden worldwide. However the current standard drugs used can often only relieve symptoms, and their ability to reach the brain is limited due to the protective properties of the blood-brain barrier, BBB [1].The BBB’s neurophysiological purpose is to keep

Revolutionizing Solar Cells with Quantum Dots

Energy, Quantum dots / /

Introduction The great aspect of solar cells is that they are producing non-polluting renewable energy by absorbing photons i.e. sunlight, and by extension converting the energy  of the photon to electrical energy for applications or conservation.  One of the main challenges in the photovoltaic industry is the 33% efficiency limit for any traditional solar cell

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

Lithium Sulfur the Next-Gen Lithium Ion Battery?

Energy / /

The lithium ion battery chemistries are reaching their theoretical limits. The transition to sustainable energy sources such as solar- and wind power requires large energy storage systems to counter their intermittency. Furthermore, the electrification of the transportation sector increases the demand for higher specific capacities i.e., the capacity to weight ratio. The needs are right

Pushing the Boundaries of Lithium-Ion Batteries With Nanotechnology

Energy / /

Note: Image adopted from UCL Faculty of Mathematical and Physical Sciences at http://www.ucl.ac.uk/maps-faculty/potw/potw/potw1313 Today it is hard to imagine a world where smartphones, laptops, smartwatches, and electric vehicles are not rechargeable. This indispensable attribute is thanks to the lithium-ion battery (LIB) which was first commercialized by Sony and Asahi Kasei in 1991 [i]. Our demand
