In this study, the graphene-modified Al foils are prepared to assemble lithium ion batteries (LIBs) through a three-step approach comprising: (1) deposition of polyamic acid (PAA) on substrate; (2) curing PAA form polyimide (PI)-coated foils; (3) converting PI into porous graphene by CO2 laser irradiation. With integration derived (PDG) in LIBs, inserted PDG layer can enhance adhesion and inter...

The control of surface wettability is a technological key aspect and usually poses considerable challenges connected to high cost, nanostructure, durability, especially when aiming at patterning with extreme contrast. This work shows simple scalable approach by using laser-induced graphene (LIG) locally inert atmosphere continuously tune the polyimide/LIG from hydrophilic superhydrophobic (Φ ∼ ...

Abstract The light scribe (LS) technique has been applied to reduce graphene oxide (LSGO) over a flexible substrate be used as humidity sensor. Graphene (GO) suspension was drop casted Polyethylene terephthalate (PET) and then reduced inside conventional digital video disc (DVD). Interdigitated electrode precisely fabricated with dimensions of the finger length 450 μm width 20 μm. prepared mate...

graphene oxide was prepared using modified hummers method. stable ethylene-glycol nanofluids containing graphene oxide nanosheets were provided. nd: yag pulsed laser was applied to prepare reduced nanofluids. experimental results revealed that thermal conductivity of the nanofluids is increased with increasing the concentration of graphene oxide (go) in ethylene glycol. the enhancement ratio of...

A scanning laser rangefinder metrology system for the 100-meter Green Bank Telescope is de¬ scribed. Use of this system for correction of the primary reflector's shape and pointing of the tele¬ scope is described.

The authors present a novel sensing platform for disposable electrochemical, non-enzymatic glucose sensor strip at physiological pH. material is based on dendritic gold nanostructures (AuNs) resembling feather branches, which are electrodeposited onto laser-scribed 3D graphene electrode (LSGE). LSGEs were fabricated via one-step laser scribing process commercially available polyimide sheet. Thi...

We demonstrate a tunable hybrid Graphene-Nd:YAG cladding waveguide laser exploiting the electro-optic and the Joule heating effects of Graphene. A cladding Nd:YAG waveguide was fabricated by the ion irradiation. The multi-layer graphene were transferred onto the waveguide surface as the saturable absorber to get the Q-switched pulsed laser oscillation in the waveguide. Composing with appropriat...
