Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Sonochemical synthesis of silver nanoparticles using orange juice: Cytotoxic behaviour and applications

Hybrid Advances
One-pot open beaker green synthesis of silver nano-particles (Ag NPs) by ultrasound energy at room temperature is presented. Citrus fruit-mediated Ag NPs formation was monitored by observing surface plasmon resonance (SPR) by UV–Visible measurements ...

Engineered magnetoconductance in InAs nanowire quantum dots [PDF]

, 2015
Magnetoconductance is the change in the electrical transport properties of a solid state system in response to an applied magnetic field, determined by both its magnitude and orientation.

Analysing the significance of small conformational changes and low occupancy states in serial crystallographic data

FEBS Open Bio, EarlyView.
This protocol paper outlines methods to establish the success of a time‐resolved serial crystallographic experiment, by means of statistical analysis of timepoint data in reciprocal space and models in real space. We show how to amplify the signal from excited states to visualise structural changes in successful experiments.

Electrochemiluminescence of CdTe Quantum Dots and Sensitive Detection of Hemoglobin

International Journal of Electrochemical Science, 2017
CdTe quantum dots were modified to the surface of glassy carbon electrode (GCE) using Nafion, and the electrochemiluminescence (ECL) behavior of CdTe quantum dots immobilized in Nafion was investigated.

Strong spin-orbit interaction, helical hole states, and spin qubits in nanowires and quantum dots [PDF]

, 2014
Semiconducting nanowires (NWs) and quantum dots (QDs) are promising platforms for spintronics and quantum computation. Great experimental and theoretical efforts have been made to continuously improve their performances, which is evident from the large ...

Refinement of amino‐acid conformation vs. difference density maps in time‐resolved serial femtosecond crystallography data analysis

FEBS Open Bio, EarlyView.
The dFoCC pipeline starts with observed DED and resting‐state coordinates, which are then used to generate a library of triggered states. Correlation analysis of the calculated DED features of each candidate vs observed DED permits quantitative evaluation of candidate structural quality.

PbSe quantum dots grown in a high-index low-melting-temperature glass for infrared laser applications [PDF]

, 2013
PbSe quantum dots (QDs) were grown in high-refractive-index low-melting-temperature lead-phosphate glass. QDs with various sizes ranging from 2 nm to 5.3 nm were grown by controlling the growth parameters, heat-treatment temperature and time.

Molecular characterization of covRS mutations in M1UK Streptococcus pyogenes

FEBS Open Bio, EarlyView.
Group A Streptococcus (GAS) acquires covRS mutations driving a hypervirulent bacterial state, frequently associated with invasive disease‐like necrotizing fasciitis. We demonstrate that the newly emerged M1UK GAS lineage can also acquire these mutations.
