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

open access: yesHybrid 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 ...

Quantum gates between capacitively coupled double quantum dot two-spin qubits

open access: yes, 2006
We study the two-qubit controlled-not gate operating on qubits encoded in the spin state of a pair of electrons in a double quantum dot. We assume that the electrons can tunnel between the two quantum dots encoding a single qubit, while tunneling between

Optically Generated 2-Dimensional Photonic Cluster State from Coupled Quantum Dots [PDF]

open access: yes, 2010
We propose a method to generate a two-dimensional cluster state of polarization encoded photonic qubits from two coupled quantum dot emitters. We combine the proposal for generating one-dimensional cluster state strings from a single dot, with a new ...

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

open access: yesFEBS 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‐

Excellent X-band EMI shielding efficiency from engineered silver telluride (Ag2Te) nanoparticles

open access: yesNext Materials
Herein, we present one-pot synthesis of aniline mediated and 2-mercaptoethanol (2-ME) capped silver telluride (Ag2Te) nanoparticles (NPs) via a solvothermal approach.

Electrochemiluminescence of CdTe Quantum Dots and Sensitive Detection of Hemoglobin

open access: yesInternational 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.

A scalable solid-state quantum computer based on quantum dot pillar structures

open access: yes, 2000
We investigate an optically driven quantum computer based on electric dipole transitions within coupled single-electron quantum dots. Our quantum register consists of a freestanding n-type pillar containing a series of pair wise coupled asymmetric ...

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

open access: yesFEBS 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.

Spin relaxation and decoherence of holes in quantum dots

open access: yes, 2005
We investigate heavy-hole spin relaxation and decoherence in quantum dots in perpendicular magnetic fields. We show that at low temperatures the spin decoherence time is two times longer than the spin relaxation time.

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...
