Porous Zero-Mode Waveguides for Picogram-Level DNA Capture

February 13, 2019
Author(s)
Vivek Jadhav, David Hoogerheide, Jonas Korlach, Meni Wanunu
We have recently shown that nanopore zero-mode waveguides are effective tools for capturing picogram levels of long DNA fragments for single-molecule DNA sequencing. Despite these key advantages, manufacturing of large arrays is not practical due to the

Optimization of Reflectometry Experiments using Information Theory

February 1, 2019
Author(s)
Bradley W. Treece, Paul A. Kienzle, David Hoogerheide, Charles Majkrzak, Mathias Loesche, Frank Heinrich
A method based on Bayesian statistics and information theory is developed to analyze the information gain Δ}H of surface-sensitive reflectometry experiments. After presenting the underlying mathematical framework and its implementation, the method is

Ni 2 Mo 3 O 8 : Complex Antiferromagnetic Order on a Honeycomb Lattice

January 18, 2019
Author(s)
Jennifer R. Morey, Allen Scheie, John P. Sheckelton, Craig Brown, Tyrel M. McQueen
Theoretical studies have predicted the existence of topological magnons in honeycomb compounds with zig-zag antiferromagnetic (AFM) order. Here we report this discovery of zig-zag AFM order in the layered and non-centrosymmetric honeycomb nickelate Ni 2Mo

High-Pressure Synthesis of A 2 NiO 2 Ag 2 Se 2 (A=Sr, Ba) with a High-Spin Ni 2+ in Square-Planar Coordination

January 14, 2019
Author(s)
Yuki Matsumoto, Takafumi Yamamoto, Kousuke Nakano, Hiroshi Takatsu, Taito Murakami, Kenta Hongo, Ryo Maezono, Hiraku Ogino, Dongjoon Song, Craig Brown, Tassel Cedric, Hiroshi Kageyama
Square-planar coordinate Ni 2+ ions in oxides are exclusively limited to a low spin state (S = 0) owing to extensive crystal field splitting. Here we report layered oxychalcogenides A 2NiO 2Ag 2Se 2 (A = Sr, Ba) with the S = 1 NiO 2 square lattice. The
