Quantifying Molecular Properties of Hexagonal Water Clusters

open access: yesChemistryOpen, EarlyView.
Standard quantum chemical calculations on large hexagonal water clusters allow us to analyze the fundamental properties of ice‐Ih. Computed geometrical structure, energies, and vibrational spectra are astonishingly close to experimental data without the introduction of any external empirical parameters.

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

open access: yesphysica 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

open access: yesphysica 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.

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

open access: yesScience 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.

From Nano Robotic Manipulation to Nano Manipulation Robot

open access: yesSmartBot, EarlyView.
This review addresses a critical research gap by summarizing advancements in nano robotic manipulation, tracing its evolution from passive observation to autonomous nanomanipulation robots. It explores the interplay of observation, construction, and operation, unveiling fundamental principles of atomic‐scale control. The review establishes a systematic
