Plasmonics‐Enhanced Characterization of Cervid PrP (87–114) Fragment Aggregates in Solution

Journal of Biophotonics, EarlyView.
Multimodal nanophotonics platform combining plasmon‐enhanced imaging, label‐free SERS, and optical staining reveals new insights into the aggregation of the cervid PrP (87–114) fragment, an amyloidogenic sequence linked to chronic wasting disease susceptibility.

Probing Metal Tip‐Induced Bond Weakening of a Reactive Alkyne Center Aligned via a Rigid Triphenylmethane‐Based Tripod on Au(111) by TERS and DFT

Journal of Raman Spectroscopy, EarlyView.
We investigate tip‐induced bond weakening of a single alkyne center immobilized and aligned upright on Au(111) using a rigid triphenylmethane‐based tripod. By varying the tip–molecule distance, we observe shifts in the ≡C–H and –C≡C– vibrational bands via ultrahigh vacuum low‐temperature tip‐enhanced Raman scattering (TERS).

In Situ Synthesized Glycerol‐Releasing Nanocarriers Unlock Superlubricity in Oil‐Based Lubricants

Macromolecular Materials and Engineering, EarlyView.
This study presents an in situ synthesis of glycerol‐based nanocarriers in hydrophobic lubricant oils via inverse miniemulsion polymerization. Encapsulating glycerol within a glycerol‐based polyurethane shell resolves miscibility issues between glycerol and the hydrophobic base oil, yielding novel nanoadditives with tunable glycerol loading.

Evolution of Oriented Crystals of Polypropylene for Capacitor Films Subjected to High‐Temperature Stretching

Macromolecular Materials and Engineering, EarlyView.
This study compares the stretching structural evolution of two iPPs with distinct isotacticities. Deformation from spherulite to fibrillar crystal induces rapid thickening of lamellae (Lc), reduction in amorphous thickness (La), and transverse dimension (Lh).

Numerical Analysis of AgInSe2‐Based Thin‐Film Solar Cells Towards High Efficiency

Nano Select, EarlyView.
In this work, SCAPS‐1D is used to numerically explore AgInSe2‐based thin‐film solar cells. Using CuS, WSe2, and AlSb as back surface field (BSF) layers with a CdS window improves carrier separation and built‐in potential. AgInSe2's promise for high‐performance, stable, and environmentally friendly solar applications is demonstrated by the optimised CdS/

Water Co‐Adsorption in Ultrathin Films of Ionic Liquids on Pt(111)

ChemistryOpen, EarlyView.
At 100 K, IL adsorption on D2O precovered Pt(111) partially displaces interfacial water resulting in a water‐IL co‐adsorbed layer. Upon heating to 130 K, IL ions migrate to the metal interface, thereby destabilizing adsorbed water as shown by the ≈10 K reduction in its desorption temperature.

Thin Fluoride Insulators for Improved 2D Transistors: From Deposition Methods to Recent Applications

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
2D materials hold significant promise for next‐generation electronic and optoelectronic devices, but suitable gate dielectrics are still a challenge. Fluoride insulators, offering inert, dangling‐bond‐free surfaces, have recently emerged as strong candidates. This review covers recent publications on high‐quality fluoride thin‐film deposition and their

Epitaxy and Phase Stability of 2D Hexagonal Gallium Telluride on Silicon

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
Two‐stage amorphization as a function of annealing temperature of continuous, strain‐free, high‐crystalline‐quality 2D hexagonal gallium telluride on silicon obtained by van der Waals epitaxy. Controlling crystal quality during epitaxial growth is essential for the advancement of novel materials with industrial relevance.

Amorphous Hydrogenated Silicon Carbide Interlayers: Chemical, Optical, and Tribological Behavior for Improving Adhesion of Carbon‐Based Films to Ferrous Alloy

Surface and Interface Analysis, EarlyView.
ABSTRACT Diamond‐like carbon thin films have been gaining attention in the last years due to their unique properties, such as low friction coefficient and high wear resistance. However, the lack of adhesion between DLC coatings and ferrous alloys complicates their wider industrial application.
