Recently, it has been recognized that phase transitions play an important role in the
probabilistic analysis of combinatorial optimization problems. However, there are in fact …

Reduced graphene oxide/platinum supported electrocatalysts (Pt/RGO) were synthesized by
employing a fast and eco-friendly microwave-assisted polyol process, which facilitated the …

Ever increasing technological and environmental needs pose significant demands on the
removal of unwanted material from substrates. Laser irradiation has been shown to afford a …

Excimer laser ablation is demonstrated to afford a novel, highly effective method of
restoration of painted artworks. The application relies on the strong UV-absorptivity of these …

We demonstrate the direct deposition of Pt, Cr and In2O3 microstructures on glass using a
femtosecond laser assisted technique. A metal (Pt, Cr) or oxide (In2O3) source film is first …

The present work includes a laser-based methodology for the cleaning of artworks, with
emphasis on the preservation of their structural integrity and identity. Modern laser-based …

Microablation and transfer of thin metal films using ultrashort, ultraviolet laser radiation has
been studied. A KrF excimer laser (λ= 248 nm) having 500-fs pulse duration is coupled to a …

Product piracy impacts wide areas of the global economy resulting in multi-billion dollar
losses per year. Therefore, product protection technologies are required to produce security …

Identification of firearms by illuminating a base of a fired cartridge from a firearm using
axially homogenized light from various illumination angles using a holographic imaging …

A firearm comprising a gun barrel for accommodating a desired round of ammunition having
