Sub-THz Characterisation of Monolayer Graphene
Journal of Spectroscopy, 2014 We explore the optical and electrical characteristics of monolayer graphene by using pulsed optoelectronic terahertz time-domain spectroscopy in the frequency range of 325–500 GHz based on fast direct measurements of phase and amplitude.

Electrically pumped all photonic crystal 2nd order DFB lasers arrays emitting at 2.3 μm
APL Photonics, 2017 Single-mode, widely tunable laser diodes in the mid-infrared range are highly interesting for demanding spectroscopic applications involving multi-species discrimination. We report on an alternative approach using single frequency laser arrays.

Studying Slow Membrane Dynamics with Continuous Wave Scanning Fluorescence Correlation Spectroscopy
, 2006 Here we discuss the application of scanning fluorescence correlation spectroscopy (SFCS) using continuous wave excitation to analyze membrane dynamics. The high count rate per molecule enables the study of very slow diffusion in model and cell membranes,

Advanced Functional Materials, EarlyView.This work presents a programmable atomic engineering strategy for 2D materials using Å‐scale nanoreactors formed by bilayer graphene (BLG) intercalation. A new class of alkali‐iron‐chloride compounds, along with lateral heterostructures composed of monolayer alkali halides and iron chlorides, is revealed.

Interface Effects in Ultrathin Silicon on Insulator Films
Advanced Functional Materials, EarlyView.This work establishes a systematic framework to discriminate how bulk and interface phenomena affect charge transport in ultrathin P‐doped silicon‐on‐insulator (SOI) films. For Si films below 15 nm, electrical characterization demonstrates that interface states drive charge transport, shifting the metal‐insulator transition (MIT) critical dopant ...

Advanced Healthcare Materials, EarlyView.Surface‐host dialogue at the implant interface governs biological fate and osseointegration. Surface physicochemical properties of titanium (Ti) dental implants, including microgrooves, nanopatterns, nanotopography, roughness, and wettability, modulate the initial adsorption of proteins and the formation of a dynamic biointerface.
