EnKF and expectation‐maximization based parameter estimation of a convective gravity‐wave parameterization using Strateole 2 constant‐level balloon data

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An offline methodology is applied to estimate parameters of a convective gravity‐wave scheme using momentum flux (MF) observations from constant‐level balloons (left panels: pdfs of east and west MFs in green from observations and black from EnKF). The approach integrates an ensemble Kalman filter with an expectation‐maximization algorithm and permits ...

Laser‐Induced‐Structural Transformation in Ti3CNTx MXene Monitored by Raman Spectroscopy with DFT Insight

Small, EarlyView.
A multi‐wavelength Raman study of microwave‐assisted hydrothermal Ti3CNTx MXene, supported by theoretical calculations, identifies laser‐power thresholds and evaluates its ambient‐condition stability. ABSTRACT MXenes are emerging 2D nanomaterials that have attracted growing attention for their highly tunable atomic structure, composition, and surface ...

Covalent Functionalization of NiFe Layered Double Hydroxides using Tris(Hydroxymethyl)Aminomethane

Small, EarlyView.
Covalent functionalization of NiFe layered double hydroxides with tris(hydroxymethyl)aminomethane enables controlled growth, enhanced structural order, and improved processability. Temporary TRIS anchoring promotes stable water‐based inks and binder‐free electrode fabrication, leading to enhanced oxygen evolution activity and long‐term stability under ...

Broadband and Enhanced Second‐Harmonic Generation in Metallic 3R‐TaS2

Small, EarlyView.
A pronounced and robust SHG response has been observed in metallic 3R‐TaS2. It shows broadband SH conversion from 1020 nm to 1410 nm. Moreover, compared to the sapphire substrate, 3R‐TaS2 flakes with various thicknesses on the gold substrate showed different SHG enhancement; the enhancement factors range from 2.7 to 45.5.

Preventing Plasma‐Induced Resist Hardening in Molybdenum Disulfide Transistors via Sacrificial Metal Mask Lithography

Small, EarlyView.
Photoresist (PR) residue significantly degrades the electrical performance of 2D semiconductors such as MoS2. In particular, the intrinsically ultrathin nature of these materials makes them highly susceptible to damage during conventional PR cleaning procedures.

Fingerprinting Superconductors by Disentangling Andreev and Quasiparticle Currents Across Tunable Tunnel Junctions

Small, EarlyView.
Tunneling Andreev reflection spectroscopy leverages the exponential sensitivity of tunneling current to distinguish between a variety of superconducitng order parameters. Here it is shown that the additivity of excess decay rate enables clear separation of Andreev and quasiparticle currents, fingerprinting the existence of sign changing superconducting

“White and Clear” (WaC): A tunable hydrophilic tissue clearing strategy for multi‐species 3D imaging

VIEW, EarlyView.
Optical tissue clearing methods help scientists make tissues transparent to image structures deep inside organs in 3D, but many existing techniques are limited in performance and difficulty. In this study, we developed an optimized clearing method called WaC (White and Clear), which improves upon existing techniques by combining efficient tissue ...

Four‐dimensional immuno‐mechanobiomaterials: Dynamic material cues that program host response to prevent fibrosis and enable regeneration

VIEW, EarlyView.
Dynamic immuno‐mechanobiomaterials with time‐programmed mechanical adaptation orchestrate host responses through precise mechanotransduction and immune‐stromal regulation. These adaptive biomaterials minimize mechanical mismatch, attenuate the forign dy response and fibrosis, promote angiogenesis and controlled extracellular matrix remodeling, and ...

Exploring the Landscape of MgO Polymorphs: Stability and the Electronic Band Gap of Promising Candidates

Zeitschrift für anorganische und allgemeine Chemie, EarlyView.
In this study, we have investigated possible predicted polymorphs of magnesium oxide (MgO) with respect to their thermodynamic and kinetic stability, as well as their electronic properties, focusing on the possibility of tuning the band gap of the material.

DISCO: a general software tool for dislocation contrast factor calculations in diffraction analysis

Journal of Applied Crystallography, EarlyView.
DISCO is a program capable of calculating the X‐ray contrast factor for single‐ and polycrystalline materials in real time.Dislocation contrast factors (CFs) play a central role in diffraction‐based analyses of plastic deformation, linking the elastic strain fields generated by dislocations to diffraction line broadening.
