Advanced Functional Materials, EarlyView.Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

The development of platinum alloys for jewellery applications by considering both the conventional and the advanced manufacturing techniques-review paper [PDF]
MATEC Web of ConferencesThe thermophysical properties of platinum (Pt) and its alloys are key when deciding on jewellery fabrication or manufacturing techniques. They include the platinum alloys’ density, viscosity, melting point, thermal conductivity, reflectivity and surface ...

Advanced Functional Materials, EarlyView.The SERS spectra of reporter molecules adsorbed on chiral gold nanorods depends on the handedness of circularly polarized light (CPL‐SERS). The bisignate plasmonic CD spectra of chiral nanorods provides wavelength‐dependent CPL‐SERS. Selective discrimination of chiral nanorod handedness and different Raman reporters allow highly sensitive codification ...

Double Helical Plasmonic Antennas
Advanced Functional Materials, EarlyView.Plasmonic double helical antennas funnel circularly polarized light to the nanoscale, offering strong chiroptical interaction and directional light emission. Extending a single helix design tool, this study combines numerical modeling with experimental validation, revealing large, broadband dissymmetry factors in the visible range.

Analysis of Dental Gold Alloys
Journal of Dental Research, 1926 Complete chemical analyses of about 40 dental gold alloys were made as part of the investigation of their physical properties. These analyses required the determination of silver, gold, platinum, palladium, iridium, rhodium, copper, zinc, nickel, tin, manganese, iron, and magnesium. Methods as found in the literature for the determination of the above-

Advanced Functional Materials, EarlyView.The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of

Advanced Functional Materials, EarlyView.A 3D bone scaffold with osteogenic properties and capable of hardening in vivo is developed. The scaffold is implanted in a ductile state, and a phase transformation of the ceramic induces the stiffening and strengthening of the scaffold in vivo. Abstract Calcium phosphate 3D printing has revolutionized customized bone grafting.
