DOI: 10.1002/aenm.201602096 of highly conductive fillers (>107 S m−1, silver nanowires and carbon nanomaterials) into an elastomeric matrix.[23] Unlike deterministic composite, these devices are intrinsically stretchable as fillers maintain electrical contact by sliding along each other during stretching.[22] Intrinsically stretchable batteries have been reported, but none are completely elasti...

Printing with custom inks is useful for extending the gamut of printed images, for creating artistically appealing designs or for providing protection against counterfeiting (security documents). The basic colors we consider, consist of the custom inks, their superpositions and the white paper. Color separation for custom inks requires to determine the relative amounts of the basic colors allow...

Subtle variations in ink color and paper of postage stamps can affect their value and desirability to collectors and investors. Protoninduced Xray emission spectrometry (PIXE) is a generally nondestructive forensic analysis tool that reveals the concentrations of chemical elements in a sample. PIXE has been used for more than 30 years, sometimes in conjunction with other analytical methods, to ...

The effect of electron beam irradiation on a series of different writing inks is described. As the anthrax-tainted letters were discovered in October 2001, the U.S. government began to experiment with the use of the electron beam irradiation process for destroying such biological agents. Plans initially considered a large-scale countrywide use of this technology. However, over time the scope of...

A simple, microwave-assisted route for producing Au/Ag concentred sols by glucose reduction in water was developed. Ag-Au bimetallic nanoparticles stabilized by polyvinylpyrrolidone (PVP) were characterized and their catalytic activity was studied in the reduction of 4nitrophenol (4-NP) with NaBH4. Moreover they were tested as red ceramic inks for ink-jet printing technology. Since the research...

Cellulose derivatives containing associating hydrophobic groups along their hydrophilic backbone are used as rheology modifiers in the formulation of water-based spray paints, medicinal sprays, cosmetics and printable inks. Jetting and spraying applications of these materials involve progressive thinning and break-up of a fluid column or sheet into drops. Strong extensional kinematics develop i...
