Controlling Bubble and Skyrmion Lattice Order and Dynamics via Stripe Domain Engineering in Ferrimagnetic Fe/Gd Multilayers

Advanced Physics Research, EarlyView.
The density and ordering of the bubble/skyrmion lattice hosted by Fe/Gd multilayers can be significantly enhanced using an in‐plane field to align the stripe domain state. As a result, the laser‐induced breathing mode dynamics are strongly modified, showing both an increased amplitude and frequency.

Compact Terahertz Dual‐Comb Spectroscopy with All‐Digitally Generated Adaptive Clock

Advanced Physics Research, EarlyView.
This work demonstrates a compact terahertz dual‐comb spectrometer using an all‐digital adaptive clock generated on an FPGA. This system achieves high precision across 1.6 THz, resolves over 24 000 comb lines with kHz resolution, and offers enhanced stability and a simplified architecture compared to analog‐based methods.

Functional Interface Engineering Enables Selective Multicolor Upconversion in NaErF4@NaYF4 Core–Shell Nanocrystals

Advanced Physics Research, EarlyView.
A functional interface engineering strategy is proposed to tune upconversion of NaErF4@NaYF4 core–shell nanocrystals by adjusting the amount of CF3COONa in the precursor during the shell growth. It is able to introduce controllable lattice defects at the core–shell interface to manipulate energy migration paths and non‐radiative transition of Er3 ...

Enhancement of Modulation Bandwidth for VLC Utilizing Green Mini‐LED Light Source

Advanced Physics Research, EarlyView.
This paper investigates three sizes of green Mini‐LEDs for visible light communication, focusing on modulation bandwidth and the impact of atomic layer deposition (ALD) sidewall passivation. ALD significantly enhances bandwidth (up to 21.6%), confirming suppression of nonradiative recombination.

On the Influence of Catalyst Mesopore Structure in the Catalytic Cracking of Polypropylene

ChemistryEurope, EarlyView.
Catalytic cracking is a promising approach to convert polyolefin plastics into hydrocarbons. Herein, the effect of catalyst pore size in polypropylene cracking using amorphous silica–alumina with identical external acidity, but varying mesopore diameters and particle sizes, is isolated. Mesopore size has minimal effect on activity, indicating that high

Bose condensation in nonequilibrium quantum gases: An adventure in the thermodynamics of light and matter

APPROVED Nonequilibrium condensates in microcavities have been extensively analysed over the past decades. Like equilibrium condensates, they are characterised by a macroscopic population of the ground state, however, the system is subjected to gain and loss through the finite lifetime of the microcavity.

Hydrogen Bonding is Key Factor in Reversible NH3 Uptake Causing Vapochromic and Magnetochemical Switching in Ni(II) Paddlewheel Complexes

ChemistryEurope, EarlyView.
Nickel complexes showing reversible vapochromic and spin crossover behaviors upon coordination and release of NH3 were synthesized. They bear bidentate pyridazine ligands, which allows for formation of hydrogen bonds between NH3 and the ligand in the second coordination sphere.

Denaturation of Water in Alkaline Melts

Chemistry – A European Journal, EarlyView.
Vapor pressure measurements and ab initio molecular‐dynamics simulations reveal that in ultra‐alkaline media with base concentrations up to 70 mol L−1, the activity of water is dramatically reduced by strong bonding interactions. These disrupt traditional hydrogen bonding patterns, alter vapor‐liquid equilibria, and significantly change molecular ...
