Acetic acid, also known as acetate, and other products that can be developed from acetic acid are used in a variety of industries, from food production to medicine to agriculture. Currently, acetate production uses a significant amount of energy and results in harmful waste products. The efficient and sustainable production of acetate is an important target for researchers interested in improving industrial sustainability.

A paper published in Carbon Future (“CO 2 electroreduction to acetate by enhanced tandem effects of surface intermediate over Co 3 O 4 supported polyaniline catalyst”) outlines a method using a polyaniline catalyst with cobalt oxide nanoparticles to produce acetate through carbon dioxide electroreduction.

Carbon nanotube networks made with high purity and ultraclean interfaces can be used to make a tensor processing unit that contains 3,000 transistors in a systolic array architecture to improve energy efficiency in accelerating neural network tasks.

An international research collaboration, including a group from Cornell Engineering, has applied a new X-ray-based reconstruction technique to observe, for the first time, topological defects in a nanoscale self-assembly-based cubic network structure of a polymer-metal composite material imaged over a relatively large sample volume.

Large-volume high-resolution X-ray nanotomography is used to identify topological defects emerging in a self-assembled triblock terpolymer single-diamond network.

Researchers synthesize high-entropy liquid metal alloys at nanoscale, achieving atomic dispersion of noble metals and demonstrating enhanced catalytic activity for hydrogen evolution.

To remove micropollutants such as pesticides and trace chemicals from the environment, you need something equally small and cunning. One potential method is photocatalysis, which uses semiconducting nanomaterials powered by sunlight to adsorb toxic chemicals on the materials’ surface and degrade them.

Successfully innovating optoelectronic semiconductor devices depends a lot on moving charges and excitons—electron-hole pairs—in specified directions for the purpose of creating fuels or electricity.

Researchers at TMOS have developed a metasurface-enabled solenoid beam that can pull particles towards it, potentially revolutionizing non-invasive medical procedures like biopsies. This technology, which uses a thin layer of nanopatterned silicon, offers a lightweight, portable alternative to the bulky equipment previously required for such beams.

Researchers at TMOS, the ARC Centre of Excellence for Transformative Meta-Optical Systems, have made a significant initial advancement in creating tractor beams enabled by metasurfaces. These beams of light, capable of drawing particles towards them, are inspired by the fictional tractor beams seen in science fiction.

In research published in ACS Photonics, the University of Melbourne team describes their solenoid beam that is generated using a silicon metasurface. Previous solenoid beams have been created by bulky special light modulators (SLMs), however, the size and weight of these systems prevent the beams from being used in handheld devices. The metasurface is a layer of nanopatterned silicon only about 1/2000 of a millimeter thick. The team hopes that one day it could be used to take biopsies in a non-invasive manner, unlike current methods such as forceps that cause trauma to the surrounding tissues.
