Emergence of Continents Stabilized the Bioavailability of Boron

Terra Nova, Volume 38, Issue 4, Page 278-284, August 2026.
ABSTRACT Boron is an essential element for the development of life on Earth; borates stabilize ribose in prebiotic reactions and facilitate metabolism in higher plants. There is, however, a relatively narrow surface boron concentration range over which borates stabilize and serve as a micronutrient rather than a toxin.

Nanophotonic Design of Germanium‐Silicon Single‐Photon Detectors for Integrated Quantum Photonic Circuits

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
Nanophotonic Ge/Si single‐photon avalanche detectors (SPADs) employing photonic‐crystal‐enhanced optical confinement and a separate absorption–multiplication (SAM) architecture enable near‐unity internal quantum efficiency, low dark current, sub‐50 ps temporal response, and efficient telecom‐band single‐photon detection.

High‐Resolution Laser‐Induced Forward Transfer of Graphene and Graphene/hBN Heterostructures Onto SiN Photodetector Patterns

physica status solidi (a), Volume 223, Issue 13, 8 July 2026.
Laser‐Induced Forward Transfer enables the maskless, high‐resolution integration of graphene and graphene/hBN pixels onto SiN photodetector architectures. Optimized laser processing preserves graphene quality while allowing transfer down to the 15 μm scale and across complex topographies, establishing a selective, mask‐free route toward straightforward

Chip‐Integrated Metasurface‐GaAsSb Nanowire Array Photodetectors for Single‐Pixel Polarimetric Imaging

Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.
A 2×2 multiplexed GaAsSb nanowire photodetector array integrated with L‐shaped metasurfaces is developed for miniaturized infrared polarimetry. Leveraging non‐radiating anapole states that facilitate near‐field enhancement, the device demonstrates strong polarization selectivity at 835 nm.

Surface‐Plasmon‐Coupled Blue InGaN/GaN Micro‐LEDs with Oxide–Metal–Oxide Capping Layer Compatible to Chip Fabrication Process

Advanced Optical Materials, Volume 14, Issue 25, 3 July 2026.
A sidewall‐integrated oxide–metal–oxide architecture is demonstrated to overcome efficiency degradation in ultra‐small InGaN/GaN micro‐LEDs. Conformal Al2O3 passivation combined with plasmonic Ag nanoparticles enables localized surface plasmon–exciton coupling, converting surface‐related nonradiative losses into radiative emission.
