Fullerenes bridge conductive gap in organic photovoltaics: Efficient cathode interlayers made of ionene polymers refined with pendant fullerenes
In contrast to common silicon-based solar cells, organic photovoltaics (OPVs) involve organic molecules in solar power generation. Materials in OPVs are abundant and processable, cheap and lightweight, and the modules can be made flexible and with tunable properties. The major disadvantage of such materials is that achieving longevity and high performance requires elaborate settings and architectures. Optimized combinations of materials that match the electrodes remain elusive.

Opportunity's Parting Shot Was a Beautiful Panorama
This image is a cropped version of the last 360-degree panorama taken by the Opportunity rover's Panoramic Camera (Pancam) from May 13 through June 10, 2018. The view is presented in false color to make some differences between materials easier to see.

Zips on the nanoscale: New method of synthesising nanographene on metal oxide surfaces
The desired nanographenes form like dominoes via cyclodehydrofluorination on the titanium oxide surface. All ‘missing’ carbon-carbon bonds are thus formed after each other in a formation that resembles a zip being closed.

When semiconductors stick together, materials go quantum: A new study led by Berkeley Lab reveals how aligned layers of atomically thin semiconductors can yield an exotic new quantum material
The twist angle formed between atomically thin layers of tungsten disulfide and tungsten diselenide acts as a "tuning knob," turning ordinary semiconductors into an exotic quantum material.

Galactic Wind Provides Clues to Evolution of Galaxies
The magnetic field lines of the the Cigar Galaxy (also called M82) appear in this composite image. The lines follow the bipolar outflows (red) generated by exceptionally high rates of star formation.

The moiré patterns of three layers change the electronic properties of graphene
A graphene layer (black) of hexagonally arranged carbon atoms is placed between two layers of boron nitride atoms, which are also arranged hexagonally with a slightly different size. The overlap creates honeycomb patterns in various sizes.

New optical imaging system could be deployed to find tiny tumors: Near-infrared technology pinpoints fluorescent probes deep within living tissue; may be used to detect cancer earlier
MIT researchers have devised a way to simultaneously image in multiple wavelengths of near-infrared light, allowing them to determine the depth of particles emitting different wavelengths.

Why Do Some Galactic Unions Lead to Doom?
Why Do Some Galactic Unions Lead to Doom?
This image shows the merger of two galaxies, known as NGC 7752 (larger) and NGC 7753 (smaller), also collectively called Arp86. In these images, different colors correspond to different wavelengths of infrared light. Blue and green are wavelengths both strongly emitted by stars. Red is a wavelength mostly emitted by dust
