We present a new approach for cryptographic end-to-end verifiable optical-scan voting. Ours is the first that does not rely on a single point of trust to protect ballot secrecy while simultaneously offering a conventional single layer ballot form and unencrypted paper trail. We present two systems following this approach. The first system uses ballots with randomized confirmation codes and a ph...

An inkjet printed, biocompatible, heterostructure photodetector is described that was constructed using inks of photo-active molybdenum disulfide (MoS2) and electrically conducting graphene which facilitated charge collection of the photocarriers. The importance of such devices stems from their potential utility in age-related-macular degeneration, which is a condition where the photosensitive ...

The Chah-Bagh gold occurrence is located in Muteh mining district, in the central part of the Sanandaj-Sirjan zone. Gold mineralization occurs in ductile to ductile-brittle shear zones and is comparable with orogenic gold deposits. Silicification and sulfidization are the most important hydrothermal alteration features in the inner parts of altered shear zones and coincide most closely with the...

A viscoelastic response with a finite yield stress is required for filament patterning.[3] The shear-induced alignment of anisotropic building blocks, including carbon fibers,[4,5] silicon carbide whiskers,[5] alumina platelets,[3] and nanofibrillated cellulose (NFC)[6]...

A novel approach for classification and dating of the black gel pen ink entries on document was developed based on ion-pairing high-performance liquid chromatography (IP-HPLC). Ninety-three black gel pens were collected and divided into two groups, dye-based and pigment-based, by preliminary solubility test. The chromatographic conditions for separation of the dye-based black gel pen inks were ...

Nowadays, about 12% of the European and 20% of the US population are tattooed. Rising concerns regarding consumer safety, led to legal restrictions on tattoo and permanent make-up (PMU) inks. Restrictions also include bans on certain colourants. Both ink types use organic pigments for colour-giving, plus inorganic pigments for white and black and colour tones. Pigments are only sparingly solubl...

Until the middle of this century, fats and oils are the major raw material source for paints, coating and lubricating applications. These markets are completely taken over by petroleum based stocks due to their abundance and versatility. However, recent public awareness to use environmentally acceptable products that minimize pollution, are compatible to human health and readily biodegradable c...

The main driving force for implementation of printing in manufacture of flexible electronics is the possibility to reduce the cost by high speed R2R processing at ambient conditions. This work focuses on characterization of inks that can be used to print simple components or layers for various applications in electronics. More specifically, inks containing conductive polymer, poly(3,4ethylenedi...

BACKGROUND To our knowledge tattooing has never been thought of as a method of introducing nanoparticles (NPs) into the human body by the intradermal route, and as such it has never been a topic of research in nanotoxicology. The content of NPs in tattoo inks is unknown. OBJECTIVES To classify the particle sizes in tattoo inks in general usage. METHODS The particle size was measured by lase...
