Holding the Cosmos in Your Hand: Developing 3D Modeling and Printing Pipelines for Communications and Research

open access: yesFrontiers in Earth Science, 2020
Three-dimensional (3D) visualization has opened up a Universe of possible scientific data representations. 3D printing has the potential to make seemingly abstract and esoteric data sets accessible, particularly through the lens of translating data into ...

Poly(Alkoxythiophene) Rod‐Coil Block Copolymers for Organic Electrochemical Transistors

open access: yesAdvanced Materials, EarlyView.
We present the first synthesis of poly(3‐alkoxythiophene) rod‐coil block copolymers as a new architecture for OMIECs. Incorporating PEG and PLLA coils can enhance device performance beyond the homopolymer. The figure‐of‐merit depends uniquely on coil length.

Elasticity‐Driven Periodic Polarization Patterns in a Chiral Ferroelectric Nematic Fluid

open access: yesAdvanced Materials, EarlyView.
Chiral polar ferroelectric nematic fluids exhibit spontaneous formation of stripe, square, and hexagonal polarization textures under confinement. Controlled by thickness and anchoring, these patterns produce spatially modulated nonlinear optical responses.

Strong Coupling in Bulk Nanoplasmonic Nanoplatelet Perovskite Scintillators

open access: yesAdvanced Materials, EarlyView.
A bulk scintillating nanocomposite is engineered from CsPbBr3 nanoplatelets and Ag nanocubes to support exciton–plasmon strong coupling under X‐ray excitation. The resulting hybrid polaritonic states appear directly in radioluminescence, opening a route toward polariton‐enabled scintillator design beyond conventional Purcell enhancement.

Gaussian Process Modeling Coronal X-Ray Variability of Active Galactic Nuclei

open access: yesThe Astrophysical Journal
The corona is an integral component of active galactic nuclei (AGNs) that can produce the X-ray emission. However, many of its physical properties and the mechanisms powering this emission remain a mystery.

Parity‐Dependent THz Harmonic Generation in Electrically Pumped Micro‐Lasers Exploiting Topological Insulator–Metamaterial Gratings

open access: yesAdvanced Materials, EarlyView.
Topological insulator–metamaterials integrated with electrically driven terahertz quantum cascade lasers enable parity‐dependent harmonic generation. Bulk‐dominated Bi2Se3 favors third‐harmonic emission at 9.96 THz, whereas topological‐surface‐state‐dominated Bi2Se3, Bi2Te3, and (Bi,Sb)2Te3 generate strong second harmonics near 6.5 THz.

Increasing Lipid Nanoparticle mRNA Copy Number Improves Transfection Potency

open access: yesAdvanced Materials, EarlyView.
As lipid nanoparticle (LNP) systems are the leading platform for in vivo nucleic acid delivery, improving transfection potency of these systems is of considerable interest. In this work, we explored a post‐mixing formulation method involving a two‐step buffer exchange that increased the number of mRNA copies within each LNP while reducing the number of

Aberration/Retardation Analysis of PSR B1451-68’s Profiles from Decimeter to Meter Wavelengths: Emission Heights and Implications for ‘Radius-to-Frequency Mapping’

open access: yesThe Astrophysical Journal
Measurements of pulse profiles over a large frequency range can be used to investigate the frequency dependence of emission heights using aberration/retardation (A/R) analysis.

Robust Spin Splitting and Fermiology in the Layered Altermagnet CoNb4${\rm CoNb}_4$Se8${\rm Se}_8$

open access: yesAdvanced Materials, EarlyView.
The emergence of an altermagnetic phase is demonstrated in the cobalt‐intercalated superconducting 2H‐NbSe2 polymorph. A combined theoretical and experimental approach directly probes the magnetism, the altermagnetic lifting of Kramers degeneracy, and the electronic phase space, establishing CoNb4Se8 as the first g‐wave altermagnetic layered material ...

dolphin: A Fully Automated Forward-modeling Pipeline Powered by Artificial Intelligence for Galaxy-scale Strong Lenses

open access: yesThe Astrophysical Journal
Strong gravitational lensing is a powerful tool for probing the internal structure and evolution of galaxies, the nature of dark matter, and the expansion history of the Universe, among many other scientific applications.
