Voltage‐Reconfigurable Magneto‐Ionic Nanolayers in Dot Arrays for Probabilistic, Materials‐Engineered Security Primitives

Advanced Science, EarlyView.
A magneto‐ionic security‐by‐materials‐design strategy exploits voltage‐driven N3– migration in selectively contacted FeCoN dots, creating reconfigurable sub‐15 nm ferromagnetic sublayers with deterministic and/or probabilistic (single‐domain↔vortex) states, voltage‐tunable probabilities and fully stochastic orientation/chirality.

Clock-Modeled Ternary Spatial Relations for Visual Scene Analysis [PDF]

, 2013
The analysis and the description of complex visual scenes characterized by the presence of many objects of interests involve reasoning on spatial relations such as “above”, “below”,“before”, “after” and “between”.

Transfer matrix method solving interface optical phonons in wurtzite core-multishell nanowires of III-nitrides

AIP Advances, 2016
Within the framework of dielectric continuum and Loudon’s uniaxial crystal models, the transfer matrix method (TMM) is developed to investigate interface optical phonons (IOPs) in cylindrical wurtzite core-multishell nanowires (CMSNWs) consisting of ...

Revealing the Nanoscale Morphology Changes of Polymer Electrolyte Membrane Fuel Cell Catalyst Layers due to Conditioning

Advanced Science, EarlyView.
We apply ex situ and in situ scanning transmission X‐ray microscopy to reveal the structural degradation of polymer electrolyte membrane fuel cell catalyst layers due to conditioning and thermal heating of the catalyst coated membrane. We observe a redistribution of the ionomer and carbon‐black in the catalyst layer, as well as nanoscale membrane ...

Synthesis and characterization of a new ternary nitride, Ca3VN3

Journal of Solid State Chemistry, 1992
We have synthesized a new ternary nitride, Ca 3 VN 3 , from the binary nitrides at high temperature. The refined structure was solved in the P 2 1 / m space group with lattice constants a =6.717(2), b =5.064(2), c =6.720(3) A, β =78.88(3)°, Z =2, R =3.2%, and R w =3.7%. The structure is related to the recently reported A 3 M N 3 compounds

Triple‐Level Content‐Addressable Vertical NAND Flash Memory

Advanced Science, EarlyView.
Commercial triple‐level‐cell V‐NAND flash memory is transformed into a compact content‐addressable memory by directly exploiting its eight threshold‐voltage states. A parity‐split search scheme preserves storage density while enabling reliable multi‐level and don't‐care matching. Parallel word‐line search delivers up to 24‐fold higher throughput and 54.

Synthesis of Ternary Metal Nitride Nanoparticles Using Mesoporous Carbon Nitride as Reactive Template

, 2016
Mesoporous graphitic carbon nitride was used as both a nanoreactor and a reactant for the synthesis of ternary metal nitride nanoparticles. By infiltration of a mixture of two metal precursors into mesoporous carbon nitride, the pores act first as a ...
