Jan 28, 2022 (Nanowerk News) Drilling with the beam of an electron microscope, scientists at the Department of Energy’s Oak Ridge National Laboratory precisely machined tiny electrically conductive cubes that can interact with light and organized them in patterned structures that confine and relay light’s electromagnetic signal. This demonstration is...
Invisible machine-readable 3D-printed labels that identify and track objects (w/video)
Jan 28, 2022 (Nanowerk News) If you download music online, you can get accompanying information embedded into the digital file that might tell you the name of the song, its genre, the featured artists on a given track, the composer, and the producer. Similarly, if you download a digital photo,...
2D Materials could be used to simulate brain synapses in computers

Electrochemical random access...
Void-confinement effect of nanoreactor promotes heterogeneous catalysis
Jan 28, 2022 (Nanowerk News) A research team from the Hefei Institutes of Physical Science (HFIPS) of the Chinese Academy of Sciences has recently obtained a catalyst composed of the hollow carbon sphere and inner Ni nanoparticles ([email protected]), which displayed good performance when applied in the aqueous phase hydrogenation rearrangement...
Strong but thin transparent films made from cellulose nanofibers with wide applicability
Jan 27, 2022 (Nanowerk News) To meet the demand for strong and tough transparent thin films for sustainable applications, Dr Sunanda Roy from GLA University India has led a multi-national team to successfully develop a novel transparent thin film made from cellulose nanofiber (CNF) reinforced by glycerol & glutalraldehyde (reinforcing...
Dissociation mechanism of oxygen molecules on a silver surface unveiled
Jan 27, 2022 (Nanowerk News) The intricacies of how a molecule of oxygen (O2) on a silver surface separates into two oxygen atoms have been determined by RIKEN chemists (The Journal of Physical Chemistry Letters, "Dissociation mechanism of a single O2 molecule chemisorbed on Ag(110)"). This knowledge will help scientists...
Improving optical-tweezer technology with graphene
Jan 28, 2022 (Nanowerk Spotlight) Back in 1970, Arthur Ashkin of Bell Laboratories found that radiation pressure – the ability of light to exert pressure to move small objects – could be harnessed to constrain small particles (see the original 1970 paper: "Acceleration and Trapping of Particles by Radiation Pressure")....
Carbon nanotubes help deliver anticancer drug directly to its targets
Jan 28, 2022 (Nanowerk News) Fundamental science often finds applications beyond its original focus. Previously, scientists found applications for small diameter carbon nanotube porins in energy technology. Nanotube porins are tubes with walls just molecules thick that act as pores through the walls of a thin membrane of liposomes, a...
Improved retinal transplant technique ready for clinical trials
Jan 27, 2022 (Nanowerk News) Researchers led by Michiko Mandai at the RIKEN Center for Biosystems Dynamics Research (BDR) in Japan have used a genetic modification to improve human-derived retina transplants grown in the lab. After transplant into damaged mouse retinas, timed removal of certain cells from the grafts allowed...
A molecular framework to bridge experimental and computer sciences for peptide-based materials engineering
Jan 27, 2022 (Nanowerk News) Researchers in the Stephenson School of Biomedical Engineering, Gallogly College of Engineering, at the University of Oklahoma have developed a framework published in Science Advances ("Peptide framework for screening the effects of amino acids on assembly") that solves the challenge of bridging experimental and computer...
