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.

The Formation and Transformation of Low‐Dimensional Carbon Nanomaterials by Electron Irradiation

open access: yesSmall, EarlyView.
The article reviews irradiation phenomena in graphene‐ or graphite‐based nanomaterials from the scale of single atoms to tens or hundreds of nanometers. Observations dating back to the 1990s can now be explained on the basis of new results. The evolution of the understanding during three decades of research is presented, and the remaining problems are ...

Tuning Self‐Assembly of Hole‐Selective Monolayers for Reproducible Perovskite/Silicon Tandem Solar Cells

open access: yesSmall Methods, EarlyView.
This study investigates how annealing temperature affects the formation of hole‐selective self‐assembled monolayers. Advanced in situ X‐ray photoelectron spectroscopy uncovers that increasing the annealing temperature beyond the conventional 100°C reduces the thickness of 2PACz from a multilayer stack of ∼5 nm to a monolayer at 150°C and improves its ...

Nanolaminate Nano‐Optoelectrodes Enable Dual‐Channel Plasmon‐Enhanced Raman Spectroscopy for Electrochemistry

open access: yesSmall Methods, EarlyView.
This study unveils a dual‐channel electrochemical surface‐enhanced Raman spectroscopy (EC‐SERS) strategy using nanolaminate Au/Ag/Ag nano‐optoelectrodes. It concurrently monitors plasmon‐enhanced vibrational and electronic Raman scattering, revealing distinct signatures of the (AgCl)* transition state during redox reactions.

Signatures of baryon junctions in semi-inclusive deep inelastic scattering

open access: yesPhysics Letters B
Local gauge invariance of the baryon wave function leads to the emergence of a baryon junction, where three (or N, in SU(N) gauge theory) string operators merge.
