Anticariogenic Sanative Effect of Aluminum Gallium Arsenide Crystals on Hydroxyapatite Crystals
Dental caries is a progressive disease with varying phases of demineralization and remineralization, and the scope of reversing the carious lesion is increased if it is diagnosed before there is surface cavitation.

Abstract Imagers operating in the visible to near‐infrared (NIR) range play an important role in applications such as industrial sorting, security surveillance, and autonomous driving. However, conventional imaging technologies based on silicon and III–V semiconductors suffer from several limits, including restricted spectral range, high fabrication ...

Breeding switchgrass for reduced nitrogen demand
Breeding has improved switchgrass biomass yield, but productivity is still heavily dependent on nitrogen fertilizer application. The genetic diversity needed to improve nitrogen use efficiency of switchgrass remains underused, mainly because of the slow and laborious breeding process, thus leaving the crop's high nitrogen demand as a major barrier to ...

Highly indistinguishable and strongly entangled photons from symmetric GaAs quantum dots
Scalable and integratable sources of entangled-photon pairs are an important building block for quantum photonic applications. Here, Huberet al. demonstrate that droplet-etched gallium arsenide quantum dots can emit highly indistinguishable photon pairs ...

Coulometric titration of gallium in gallium arsenide.
電量滴定法によりヒ化ガリウム中のガリウムの定量を行った.分析方法としては,ガリウムに対して過剰のEDTAを加えてキレート生成させて,過剰分を電解発生させた銅(II)イオンで逆滴定するという手法を採った.そこでEDTAの純度分析を行ったところ,銅(II)イオンによる滴定条件において基礎液の濃度とpH調節が重要であった.又滴定終点は,ポテンショスタットで電位規制した作用電極上での銅(II)イオンの還元電流を利用して決定した.EDTAの純度分析の結果は99.749%となり,この値に基づいて高純度ガリウムの定量,更にヒ化ガリウム中のガリウムの定量を行った.ヒ化ガリウムを試料とした場合には共存するヒ素(V)の影響が大きいことから,ヒ素(III)への還元操作を加えた ...

Near‐Infrared Polarimetric Imaging With Nonlinear Flat‐Optics
ABSTRACT A compact and broadband polarimetric imaging platform is presented, based on second‐harmonic generation (SHG) in nonlinear flat‐optics. The system employs periodic all‐dielectric AlGaAs gratings to induce polarization‐dependent SH emission, enabling pixel by pixel direct retrieval of the full Stokes vector from an input intensity distribution ...
