The refractive index of a single atom experienced by a single photon (open access)

The refractive index of a single atom experienced by a single photon

Article describes how the refractive index of a system is often viewed as the collective response of a medium to an electromagnetic field. By studying the propagation of a single photon interacting with a two-level atom, the authors examine the dispersion behavior, calculate the phase and group velocity of the photon wave packet, and further analyze the dispersion experienced by the photon.

A brief guide to polymer characterization: structure (IUPAC Technical Report) (open access)

A brief guide to polymer characterization: structure (IUPAC Technical Report)

Article states that to bolster the series of Brief Guides released by International Union of Pure and Applied Chemistry, the authors introduce the first Brief Guide to Polymer Characterization. This article provides a concise overview of characterization methods for teachers, students, non-specialists, and newcomers to polymer science as well as being a useful manual for researchers and technicians.

Dominant Role of Hole Transport Pathway in Achieving Record High Photoconductivity in Two-Dimensional Metal-Organic Frameworks (open access)

Dominant Role of Hole Transport Pathway in Achieving Record High Photoconductivity in Two-Dimensional Metal-Organic Frameworks

Article describes how metal-organic frameworks with mobile charges have attracted significant attention due to their potential application in photoelectric devices, chemical resistance sensors, and catalysis. The authors report the mechanisms of photoinduced charge transport and electron dynamics in the conductive 2D M−HHTP MOFs and their correlation with photoconductivity using the combination of time-resolved terahertz spectroscopy, optical transient absorption spectroscopy, X-ray transient absorption spectroscopy, and density functional theory calculations.

Complexity Synchronization of Organ Networks (open access)

Complexity Synchronization of Organ Networks

Article describes how the transdisciplinary nature of science as a whole became evident as the necessity for the complex nature of phenomena to explain social and life science, along with the physical sciences, blossomed into complexity theory and most recently into complexitysynchronization. The authors use the scaling of empirical datasets from the brain, cardiovascular and respiratory networks to support the hypothesis that complexity synchronization occurs between scaling indices or equivalently with the matching of the time dependencies of the networks' multifractal dimensions.

Biophotons: New Experimental Data and Analysis (open access)

Biophotons: New Experimental Data and Analysis

Article describes how biophotons are an ultra-weak emission of photons in the visible energy range from living matter. The authors study the emission from germinating seeds using an experimental technique designed to detect light of extremely small intensity.
