Microscopic and macroscopic compaction of cohesive powders
A novel method to investigate the compaction behaviour of cohesive powders is presented. As a sample, a highly porous agglomerate formed by random ballistic deposition (RBD) of micron sized spherical particles is used. A nanomanipulator deforms thi...
Controlling light propagation: a brief review
Recent results by Hoffman et al. showed that it is possible to build a Negative Refractive Material (NIM) by interleaving InGaAs/AlInAs using current nanofabrication technologies. Their findings provide the first experimental proof of a negative refr...
Trusty URIs: Verifiable, Immutable, and Permanent Digital Artifacts for Linked Data
To make digital resources on the web verifiable, immutable, and permanent, we propose a technique to include cryptographic hash values in URIs. We call them trusty URIs and we show how they can be used for approaches like nanopublications to make not...
Ion microscopy based on laser-cooled cesium atoms
We demonstrate a prototype of a Focused Ion Beam machine based on the ionization of a laser-cooled cesium beam adapted for imaging and modifying different surfaces in the few-tens nanometer range. Efficient atomic ionization is obtained by laser prom...
Reflecting (on) the Nucleation Curve: Negative Surface Energy Stabilizes Nickel Ferrite Na…
We used a thermodynamics-informed first principles scheme, to calculate the temperature-dependent surface energies of nickel oxide (NiO) and nickel ferrite (NiFe2O4), two compounds that are known to deposit on the fuel rods in nuclear pressurized wat...
Presolar stardust in asteroid Ryugu
We have conducted a NanoSIMS-based search for presolar material in samples recently returned from C-type asteroid Ryugu as part of JAXA's Hayabusa2 mission. We report the detection of all major presolar grain types with O- and C-anomalous isotopic co...

Virtual Synthesis of Nanoscale Systems with Pre-Designed Properties: Fundamentals and Appl…
The virtual (i.e., fundamental many body quantum theory-based, computational) synthesis method is used to establish electronic templates of about 30 non-stoichiometric nanosystems composed of nickel and oxygen atoms and ranging from about 6 Å to 6 n...

Solar Activity: Triennial Report of IAU Commission 10 (2006-2009)
Commission 10 deals with solar activity in all of its forms, ranging from the smallest nanoflares to the largest coronal mass ejections. This report reviews scientific progress over the roughly two-year period ending in the middle of 2008. This has...
Edge and Width Dependent Electronic Properties of Nanoribbons of Manganese Oxide
In the present work, the structural, magnetic, and electronic properties of the two- and one-dimensional honeycomb structures of recently synthesized MnO [Zhang et al. Nat. Commun., 20, 1073-1078 (2021)] are investigated by using first principles cal...
Investigation of plasmonic evolution of atomically size-selected Au clusters by electron e…
Versatile quantum modes emerge for plasmon describing the collective oscillations of free electrons in metallic nanoparticles when the particle sizes are greatly reduced. Rather than traditional nanoscale study, the understanding of quantum plasmon d...
Enhanced ordering in length-polydisperse carbon nanotube solutions at high concentrations…
Carbon nanotubes (CNTs) are stiff, all-carbon macromolecules with diameters as small as one nanometer and few microns long. Solutions of CNTs in chlorosulfonic acid (CSA) follow the phase behavior of rigid rod polymers interacting via a repulsive pot...
Bridging Optical Sensing and Wearable Health Monitoring: A Functionalized Plasmonic Nanopi…
Continuous glucose monitoring (CGM) is vital for diabetes care, but current systems rely on invasive implants or electrochemical sensors that often cause discomfort and skin irritation. Non-invasive alternatives remain limited by low sensitivity and...
Two Optical Coherence Tomography Systems detect Topical Gold Nanoparticles in Hair follicl…
Optical coherence tomography (OCT) is an established imaging technology for in vivo skin investigation. Topical application of gold nanoshells (GNS) provides contrast enhancement in OCT by generating a strong hyperreflective signal from hair follicle...
Single-step modified electrodes for vitamin C monitoring in sweat
We demonstrate a flexible sensor for ascorbic acid detection in sweat based on single-step modified gold microelectrodes. The modification consists on the electrodeposition of alginate membrane with trapped CuO nanoparticles on top of the electrodes....
Mechanical cleaning of graphene
Contamination of graphene due to residues from nanofabrication often introduces background doping and reduces charge carrier mobility. For samples of high electronic quality, post-lithography cleaning treatments are therefore needed. We report that m...
