Non-fullerene polymer solar cells exhibit high performance and are easy to commercialize.
Rice University postdoctoral researcher Riccardo Petrolo shows one of several autonomous aerial drones being prepared to monitor for pollutants. The National Science Foundation awarded a grant to the Rice lab of electrical and computer engineer Edward Knightly to develop the platform.
The proposed wire is 'doped' with a ruthenium unit that enhances its conductance to unprecedented levels compared with previously reported similar molecular wires.
The fabrication schematic diagram of FeCo-selenide//Fe2O3 asymmetric supercapacitor (ASC). The FeCo-selenide and Fe2O3 electrodes serve as positive and negative electrodes respectively that both show excellent electrochemical performance. In addition, the fabricated ASC was connected to form a series circuit to light the "CUMT" board, which can be viewed as a promising candidate for large scale hybrid devices applications.
Gold nanoparticles tethered on a BSA-protein-protected gold surface via hairpin-DNA are moved reversibly using electric fields, while monitoring their position and DNA conformation optically via changes of its plasmon resonance (by color).
Schematic illustration of the formation of OH-terminated diamond (111) surface by water vapor annealing of H-terminated one.
At left, a scanning electron microscopy (SEM) image of an iron BDP MOF crystal; at right, an iron BDP MOF single-crystal device bonded to a platinum microelectrode array.
Electrons arranged in a wedding-cake like structure, a concentric series of insulating (red) and conducting (blue) rings, due to magnetic confinement in graphene. The height of each tier represents the energy of the electrons in that tier.
Reaction mechanism showing a proton transfer from the superacid catalyst to isobutylene. This is the first step in the PIB polymerization process.
This is Girlguiding and STEM.
At high temperatures, ceramics are susceptible to thermal-shock fractures caused by rapid temperature-changing events, such as cold water droplet contact with hot surfaces. In a novel interdisciplinary approach, engineers at the University of New Mexico report in AIP Advances the use of a cheap, simple, water-repelling coating to prevent thermal shock in ceramics. These are snapshots of hot surface and cold droplet interaction at 3 milliseconds at 300 degrees Celsius: (a) on as-received alumina ceramics and (b) on an engineered hydrophobic surface.

Elliptical orbits of bismuth surface electrons in a large magnetic field. The orientation and interference patterns of the electronic states reveal that the electrons prefer to occupy a single valley. Image created using a theoretical model of the data.
Doctoral candidate Niyousha Karimi Paridari studies electrochemical properties of various materials for use in new energy storage technologies.
Light hits the 3-D printed nanostructures from below. After it is transmitted through, the viewer sees only green light -- the remaining colors are redirected.
When a metal ion is inserted, the molecule changes geometry, acting as an on/off switch.
This is the device compared to a US dollar coin.
This is a nitrogen-vacancy (NV) center in diamond with two crossed wires for holonomic quantum gates over the geometric spin qubit with a polarized microwave.
The Department of Energy gave Distinguished Achievement awards to Argonne's Andrew Burnham, Keith Hardy, Amgad Elgowainy and Jeongwoo Han in June. The researchers help advance transportation, sustainability and mobility at the laboratory.
This is a time-lapse photo for various designs of developed magnetic active material.

The batteries were made by stacking various layers via thin-film deposition methods. The LNMO/Li3PO4 interface showed spontaneous migration of Li ions and had an unprecedentedly low resistance.
This brightly colored dragon was produced by 3D printing, using gold nanorods as photosensitizers.
