Inverse Design Software Automates Design Process for Optical, Nanophotonic Structures

WASHINGTON, D.C., March 10, 2020 — Stanford University researchers created an inverse design codebase called SPINS that can help researchers explore different design methodologies to find fabricable optical and nanophotonic structures.

In the journal Applied Physics Reviews, from AIP Publishing, Logan Su and colleagues review inverse design’s potential for optical and nanophotonic structures, as well as present and explain how to use their own inverse design codebase.

“The idea of inverse design is to use more sophisticated optimization algorithms and automate the search for a structure,” Su explained. “The ultimate goal is to have a designer input their desired performance metrics and simply wait for the algorithm to generate the best possible device.”

Simple Self-Charging Battery Offers Power Solutions for Devices

WASHINGTON, D.C., February 25, 2020 — A new type of battery combines negative capacitance and negative resistance within the same cell, allowing the cell to self-charge without losing energy, which has important implications for long-term storage and improved output power for batteries.

These batteries can be used in extremely low-frequency communications and in devices such as blinking lights, electronic beepers, voltage-controlled oscillators, inverters, switching power supplies, digital converters and function generators, and eventually for technologies related to modern computers.

Highly Sensitive Sensors Show Promise in Enhancing Human Touch

WASHINGTON, D.C., February 18, 2020 — People rely on a highly tuned sense of touch to manipulate objects, but injuries to the skin and the simple act of wearing gloves can impair this ability. Surgeons, for example, find that gloves decrease their ability to manipulate soft tissues. Astronauts are also hampered by heavy spacesuits and find it difficult to work with equipment while wearing heavy gloves.

In this week’s issue of Applied Physics Reviews, by AIP Publishing, scientists report the development of a new tactile-enhancement system based on a highly sensitive sensor. The sensor has remarkable sensitivity, allowing the wearer to detect the light brush of a feather, the touch of a flower petal, water droplets falling on a finger and even a wire too small to be seen.

Tiny Magnetic Structures Enhance Medical Science

WASHINGTON, D.C., January 28, 2020 — Small magnetic objects, which have been used successfully in technological applications such as data storage, are showing promise in the biomedical field. Magnetic nanostructures have interesting properties that enhance novel applications in medical diagnosis and allow the exploration of new therapeutic techniques.

Isolating and separating cells from a blood or tissue sample is crucial for a variety of medical applications, such as gene therapy or cancer diagnosis and treatment. Standard procedures involve filtration and centrifugation, but cells of similar sizes or densities cannot be separated this way.

Communications Device Offers Huge Bandwidth Potential

WASHINGTON, D.C., December 10, 2019 — Scientists at the University of Illinois have created sugar cube-sized blocks of an electromagnetic material with potential to transform communication networks.

Several countries are building futuristic communication systems using higher frequency electromagnetic waves to transfer more data at faster rates, but they have lacked network components to handle these higher bandwidths. Researcher J. Gary Eden proved his new device can rapidly switch functionality to perform the varied tasks needed to support a network with carrier frequencies of over 100 gigahertz. The miniscule-scale architecture concealed within the sugar cube blocks is described in Applied Physics Reviews, from AIP Publishing.

Ternary Acceptor and Donor Materials Increase Photon Harvesting in Organic Solar Cells

WASHINGTON, D.C., November 26, 2019 — Organic solar cells are steadily improving as new materials are developed for the active layer, particularly when materials are stacked in a bulk heterojunction design that takes advantage of multiple combined absorption windows to use photons at more parts of the spectrum.

Non-fullerene materials are especially promising in binary organic solar cells, making it possible to tune optical and energy properties. But, despite their advantages, these materials have narrow absorption windows. Attempts to incorporate non-fullerene acceptors into organic solar cells include adding a third component to increase photon harvesting.

3D Printing, Bioinks Create Implantable Blood Vessels

WASHINGTON, D.C., October 22, 2019 — A biomimetic blood vessel was fabricated using a modified 3D cell printing technique and bioinks, which were formulated from smooth muscle cells from a human aorta and endothelial cells from an umbilical vein. The result is a fully functional blood vessel with a dual-layer architecture that outperforms existing engineered tissue and brings 3D-printed blood vessels several fundamental steps closer to clinical use…..

Creating Miracles with Polymeric Fibers

WASHINGTON, D.C., October 15, 2019 — “Polymers are very, very useful materials when it comes to modern applications.”

Mohan Edirisinghe leads a team of researchers at University College London studying the fabrication of polymeric nanofibers and microfibers — very thin fibers made up of polymers. The group describes a study comparing fabrication techniques for these fibers without the use of electric fields in Applied Physics Reviews, from AIP Publishing….

Treating Solar Cell Materials Reveals Formation of Unexpected Microstructures

WASHINGTON, D.C., July 30, 2019 — Recent advances in solar cell technology use polycrystalline perovskite films as the active layer, with an increase to efficiency of as much as 24.2%. Hybrid organic-inorganic perovskites are especially successful, and they have been used in optoelectronic devices including solar cells, photodetectors, light-emitting diodes and lasers…

Improving Efficiency, Brightness of Perovskite LEDs

WASHINGTON, D.C., July 30, 2019 — Advances in organic phosphorescent materials are opening new opportunities for organic light-emitting diodes for combined electronics and light applications, including solar cells, photodiodes, optical fibers and lasers…
