LipoGels: Robust Self‐Lubricating Physically Cross‐Linked Alginate Hydrogels Embedded with Liposomes

Advanced Functional Materials, EarlyView.
Physically cross‐linked alginate hydrogels embedded with 1,2‐dipalmitoyl‐sn‐glycero‐3‐phosphocholine liposomes (LipoGels) are prepared under optimized conditions to avoid shrinkage and achieve structural uniformity. LipoGels demonstrate robust mechanical strength (Young's modulus ≈1 MPa), excellent lubrication (friction coefficient ≈0.021), and ...

The Effect of Amino Acids on the Formation of Amorphous Calcium Carbonate Nanoparticles

Advanced Functional Materials, EarlyView.
Biomineral formation often proceeds via the assembly of amorphous calcium carbonate (ACC) nanoparticles with narrow size distributions. Using in situ SAXS coupled to a stopped‐flow device, we follow synthetic ACC formation with a 10 ms time resolution and show that amino acids narrow the size distribution at low supersaturation, highlighting their key ...

A New Family of Ternary Intermetallic Compounds with Dualistic Atomic Ordering – The ZIP Phases

Advanced Materials, EarlyView.
The ZIP phases are ternary intermetallic compounds with dualistic atomic ordering, i.e., they exhibit one face‐centered cubic (fcc; space group Fd3¯$\bar 3$m) variant and one hexagonal (space group P63/mmc) variant. The ZIP phases in the Nb‐Si‐Ni system are the Nb3SiNi2 (fcc) and Ni3SiNb2 (hexagonal) ternary IMCs, crystal structure schematics of which ...

Detecting the Six Polytypes of Five‐Layer Graphite

Advanced Materials, EarlyView.
The six possible periodic crystals—so‐called polytypes of Penta layer graphene are identified using Raman, second harmonic, and electric surface potential measurements. The measurements reveal the polytypes’ abundance, relative stability, and annihilation dynamics, crucial for future multiferroic SlideTronic applications.

Light Induced Training of 3D Printed Mechanical Metamaterials

Advanced Materials Technologies, EarlyView.
A new 3D‐printable material that stiffens under UV light is integrated into the architecture of mechanical metamaterials to realize trainable systems. Local stiffening amplified by rational design enables closed‐loop systems with tunable properties guided by UV irradiation. The resulting structures gradually adapt shape or resistance, demonstrating how

Multiparameter Closed‐Loop Control to Advance Reliability of Aerosol Jet Printing

Advanced Materials Technologies, EarlyView.
A multiparameter framework for closed‐loop control of aerosol jet printing is developed to improve process consistency over both short and long timescales. By creating a control architecture responsive to the dynamic behavior of the printing system, variability in functional electrical properties is significantly reduced over extended duration printing,

Abelian and Tauberian results for the fractional Fourier cosine (sine) transform

AIMS Mathematics
In this paper, we presented Tauberian type results that intricately link the quasi-asymptotic behavior of both even and odd distributions to the corresponding asymptotic properties of their fractional Fourier cosine and sine transforms.

Asymptotic Behavior of a Tumor Angiogenesis Model with Haptotaxis

Mathematics, 2020
This paper considers the existence and asymptotic behavior of solutions to the angiogenesis system p t = Δ p − ρ ∇ · ( p ∇ w ) + λ p ( 1 − p ) , w t = − γ p w β in a bounded smooth domain Ω ⊂ R N ( N = 1 , 2 ) , where ...

Strong and Weak Coupling Nanophysics with Free Electron Beams

Advanced Optical Materials, EarlyView.
This paper focuses on a short review of the study of the coupling between optical excitations at the nanometer scale, made possible by recent advances in free electron beam spectroscopies. In particular, plasmon–plasmon, plasmon–exciton, and plasmon–phonon couplings are reviewed. Abstract The work of Luis M.

Polar Indirect Valley as a Limiting Factor for Radiative Efficiency in Gold‐Based Mixed‐Valence Double Perovskites

Advanced Optical Materials, EarlyView.
This work addresses a common issue in many double perovskites: their weak luminescence. Using the example of promising infrared‐bandgap mixed‐valence gold halide double perovskites, it demonstrates strong polar electron‐phonon coupling. Temperature‐dependent spectroscopy reveals that bright polarons are favored at low temperature, while a dark low ...
