Controlled Formation of Carbon Nanotubes and Nanotube Junctions from Bilayer Graphene

Small, EarlyView.
Twisted bilayer graphene is cut using a scanning transmission electron microscope to create individual chiral carbon nanotubes and interconnected nanotube junctions. The sculpting is facilitated by in situ heating and automated beam control. Bilayer graphene ribbons with a width of less than approximately 4 nm spontaneously convert to CNTs, while no ...

Water‐Mediated Ligand Dynamics Enable Solution‐Phase Self‐Assembly of Perovskite Nanocrystals Into 3D Ordered Architectures

Small, EarlyView.
Cooperative water‐mediated ligand–ligand interactions in a mixed‐ligand environment regulate nanocrystal growth and assembly, enabling rapid self‐assembly of CsPbBr3 nanocrystals into structurally stable and highly emissive superlattices directly in the liquid phase.

Double Slag Operating Standard for Mitigation of CO2 Emissions in Basic Oxygen Steelmaking

steel research international, EarlyView.
Basic oxygen furnace (BOF) steelmaking uses a double slag process (DSP) to produce low‐phosphorus steel. To reduce carbon emissions in a BOF, the hot metal ratio (HMR) must be lowered. The present article describes the optimal conditions for DSP operations under low‐HMR conditions: temperature of 1360 ± 5 °C, total Fe content of 10 ± 2 wt%, basicity (=

Matrix‐Isolation Electron Paramagnetic Resonance Studies of Radical Ions and Neutral Radicals Generated by Radiolysis of Organic Molecules at Cryogenic Temperatures

The Chemical Record, EarlyView.
By selecting an appropriate matrix and irradiating the matrix containing a trace amount of solute at low temperatures, ionic or neutral radicals derived from the solute can be generated and trapped in the matrix. EPR spectroscopy of these samples yields highly detailed information on the radicals, inaccessible by other experimental techniques. Electron

Adaptive harvesting of two trophic levels stabilises predator–prey dynamics. Simulations with Eurasian lynx and European roe deer

Wildlife Biology, EarlyView.
Europe has seen the recovery of many species of wild herbivores, which are now widespread across much of the continent. In addition, large carnivores are also recolonising many European countries. Most ungulates are managed through hunting, but natural predation can also have a significant influence in many areas.
