Link found between golden ratio and atomic symmetry
The researchers discovered that when they tuned the system and artificially introduced more quantum uncertainty, the chain of atoms acted like a nanoscale guitar string. They used a special probe, neutron scattering', which enabled them to see the actual atomic scale

Bridging the gap with a "stepping stone" for more solar energy
Converting the abundant energy from the sun into a form convenient for human use has been a long standing dream for sustainable generation of environmentally clean energy. With the seminal discovery of water splitting by Fujishima and Honda in the early 1970s [1], titanium dioxide (Ti...

The effects of boron dopings and boron grafts on the mechanical properties of single-walled carbon nanotubes
The effects of boron doping and boron grafts on the mechanical behaviour of armchair (6, 6) and zigzag (10, 0) single-walled carbon nanotubes (SWCNTs) under axial loading are investigated using the molecular dynamics (MD) simulation method. The results show that

Snap-through instability of graphene on substrates
We determine the graphene morphology regulated by substrates with herringbone and checkerboard surface corrugations. As the graphene-substrate interfacial bonding energy and the substrate surface roughness vary, the graphene morphology snaps between two distinct states: 1) cl...

Nonequilibrium molecular dynamics for bulk materials and nanostructures
We describe a method of constructing exact solutions of the equations of molecular dynamics in settings out of equilibrium. These solutions correspond to some viscometric flows, and to certain analogs of viscometric flows for fibers and membranes that have one or more dimensions of atomi...

Bending and wrinkling as competing relaxation pathways for strained free-hanging films
A thin film subject to compressive strain can either bend (for large strain gradient) or wrinkle (for small strain gradient). The bending is traditionally used in thermostats (bimetal stripes), but couple of years ago, it was extended to the nanoscale thin films which can bend and roll-...
