Graphene Nanoplatelets (GNP) as a Functional Filler for Styrene‐Butadiene Rubber (SBR)

Polymer Composites, EarlyView.
Spider chart showing the change in selected properties on inclusion of GNP in SBR relative to carbon black (CB) filled SBR. ABSTRACT The carbon footprint of synthetic rubber is poor, including its production and the use of carbon black as a filler, which is obtained from non‐renewable feedstocks.

Combined Atomic Force Microscopy and Raman Spectroscopy Investigation of Fingerprints Detriment upon Liquid Exposure for Forensic Analysis

physica status solidi (b), EarlyView.
Modern forensic investigation requires advanced analysis techniques combining chemical detection and high spatial resolution. In the present work, a Raman spectrometer coupled to an atomic force microscope (AFM) is applied to fingerprints detection and the study of their detriment in ambient conditions (exposure to water and acid water).

Weak Antilocalization Effect for Detection of Dirac Fermions in Capped Bi2Te3 Epitaxial Film

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
The transport properties of a sample grown by molecular beam epitaxy are investigated. The sample consists of a Bi2Te3 epitaxial film deposited on BaF2 substrate and capped with a BaF2 cap to prevent the topological surface states (TSS) deterioration.

Atomic Scale Visualization of Vibrational Modes in Armchair Graphene Nanoribbon

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
To visualize the vibrational modes of armchair graphene nanoribbons and verify theories, a functionalized scanning tunneling tip is used to enhance the inelastic tunneling channel over the elastic one. Results show that edge phonons are localized than bulk phonons with little influence from substrate interactions.

Two‐Photon Interference from an InAs Quantum Dot Emitting in the Telecom C‐Band

Advanced Quantum Technologies, EarlyView.
A telecom C‐band emitting quantum dot integrated with a circular Bragg grating cavity demonstrates two‐photon interference visibility of 71.9%, which is currently state‐of‐art. The improved two‐photon interference visibility is enabled by optimized growth and Purcell enhancement.

Reconceptualizing Out‐of‐Field Teachers' Professional Development and Classroom Implementation: A Boundary Crossing Approach

Science Education, EarlyView.
ABSTRACT Reform‐oriented instruction is advocated in secondary science, encouraging students to engage with the experimental and epistemic practices of science. It is challenging for teachers though, especially for out‐of‐field teachers. This study focuses on biology and chemistry teachers who are called to teach middle‐school physics.
