Silicon‐Embedded Multifunctional Heterogeneous Integration for Miniaturized Photoplethysmography Detection Devices

open access: yesAdvanced Science, Volume 13, Issue 40, 17 July 2026.
ABSTRACT The multifunctional integration of chips with high flexibility and scalable manufacturing is crucial for enhancing chip performance, reducing chip size, and simplifying chip design. However, balancing volume, cost, flexibility, and functionality using traditional heterogeneous integration methods is challenging.

Highly Efficient Selection of High-redshift Emission-line Galaxies for Future DESI-like Surveys with Deep Multiband Imaging

open access: yesThe Astronomical Journal
Emission-line galaxies (ELGs) are an important tracer of baryon acoustic oscillations (BAOs) and large-scale structure at z  > 1. In this work, we investigate the feasibility of using deep wide-area multiband imaging (e.g., from the Rubin Observatory) to

A Review of Failure Modes and Safety Strategies of Lithium‐Ion Batteries from Materials to Systems

open access: yesAdvanced Science, Volume 13, Issue 42, 28 July 2026.
A cascade‐aware framework is presented for lithium‐ion battery safety, linking thermal runaway initiation, acceleration, runaway reaction, and propagation with material‐, cell/pack‐, and system‐level interventions. By integrating failure mechanisms, quantitative safety indicators, and staged interception strategies, this review highlights how safer ...

Mid-infrared Ensemble Variability of Broad-line and Narrow-line Seyfert 1 Galaxies

open access: yesThe Astrophysical Journal
We utilized multiepoch archival data from the Wide-field Infrared Survey Explorer to compare the variability at 3.4 μ m (W1 band) and 4.6 μ m (W2 band) of broad-line Seyfert 1 (BLSy1) galaxies and narrow-line Seyfert 1 (NLSy1) galaxies by employing the ...

Germanium‐Based Mid‐Infrared Integrated Photonics

open access: yesLaser &Photonics Reviews, Volume 20, Issue 14, 22 July 2026.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Early Results from the Coma Legacy IFU Survey (CLIFS): Ram Pressure Induced Shocks and Ionization in Jellyfish Tails

open access: yesThe Astrophysical Journal
Jellyfish galaxies, which exhibit tails of gas opposite to their direction of motion, are a galaxy population showcasing the most extreme effects of ram pressure stripping (RPS).

Circular Differential Scattering Spectroscopy for the Characterization of Single Chiral Nanostructures: Fundamentals, Development, and Perspectives

open access: yesNational Materials, Volume 1, Issue 1, Page 48-71, July 2026.
Circular differential scattering (CDS) spectroscopy relies on a modified dark‐field optical microscope to study single chiral nanostructures, avoiding the averaging effects of ensemble methods. Recently achieving improved detection limits of 1.5%, this robust technique analyzes plasmonic chirality and molecular interactions, with the future goal of ...

MOSDEF-3D: Keck/OSIRIS Maps of the Ionized Interstellar Medium in z ∼ 2 Galaxies

open access: yesThe Astrophysical Journal
We present spatially resolved rest-frame optical emission line maps of four galaxies at z  ∼ 2 observed with the Keck/OH-Suppressing Infra-Red Imaging Spectrograph to study the physical conditions of the interstellar medium (ISM) at cosmic noon.

UNCOVERing the High-redshift AGN Population among Extreme UV Line Emitters

open access: yesThe Astrophysical Journal
JWST has revealed diverse new populations of high-redshift ( z  ∼ 4–11) active galactic nuclei (AGNs) and extreme star-forming galaxies that challenge current photoionization models.

A NOEMA pilot survey of [C II] line emission in luminous galaxies at z  ≈  6

open access: yesAstronomy & Astrophysics
We present Northern Extended Millimeter Array (NOEMA) observations of four luminous galaxies at z ∼ 6, when the Universe was less than ∼1 Gyr old. These galaxies are detected in the [C II] 158 μm fine-structure line, and three also exhibit underlying ...
