In this work, we theoretically propose a highly-flexible optical bistable switch based on a suspended monolayer Z-shaped graphene nanoribbon nanoresonator (NR). It is shown that bistable nonlinear absorption and refraction response will appear in the strong exciton-NR coupling rme. Specifically, we plot bistability phase diagrams within the system’s parameter subspace and derive the critical conditions...
Exploration of high temperature organic magnets is one attractive topic in the fields of physics, chemistry, and material science. Here, we show that by using a two-step method - ultrasound treatment and low temperature annealing, room temperature ferromagnetism can be produced in naphthalene, the simplest polycyclic aromatic hydrocarbon consisted of two fused benzene rings. The existence of hydrogen...
We herein report the synthesis of heteroatoms doped, high surface area microporous activated carbons (AC) by utilisation of Coca Cola® as a potential source of waste biomass, for applications as CO2 adsorbent and electrodes of supercapacitors. N, S dual doped carbon spheres are firstly obtained by hydrothermal treatment of Coca Cola® and then thermally activated by either KOH or ZnCl2. The resulting...
High-quality double-walled carbon nanotubes (DWCNTs) thin-films have been fabricated in one-step by the catalytic chemical vapor deposition gas-flow reaction process with acetone as a carbon source in an argon flow. The DWCNTs film is formed through the self-assembly of the DWCNTs in the gas flow, which is achieved by controlling the gas rates in the synthesis reaction. The DWCNT film is self-supported...
Macroscopic films and fibers of chemical vapor deposition (CVD) grown carbon nanotubes (CNTs) were electrically sparked between the nanotube assemblies and the electrode of a direct current power source. Microstructural analyses showed that the electric sparking ablated the ‘hard’ amorphous shells from the CNTs in the film and reshaped them into nanosize particles. This led to the formation of the...
