Extraction and Sample Preparation [PDF]

open access: yesInternational Journal of Analytical Chemistry, 2015
As everyone knows, the role played by extraction and sample preparation in the analytical sciences cannot be overemphasized. Despite tremendous advances in chromatography, detection, and other aspects of analysis, extraction and sample preparation remain a preanalysis ritual of critical importance.

Preparing Many Copies of a Quantum State in the Black-Box Model [PDF]

open access: yesPhys. Rev. A 105, 062440 (2022), 2022
We describe a simple quantum algorithm for preparing $K$ copies of an $N$-dimensional quantum state whose amplitudes are given by a quantum oracle. Our result extends a previous work of Grover, who showed how to prepare one copy in time $O(\sqrt{N})$.

Variational Quantum Algorithms for Gibbs State Preparation [PDF]

open access: yes, 2023
Preparing the Gibbs state of an interacting quantum many-body system on noisy intermediate-scale quantum (NISQ) devices is a crucial task for exploring the thermodynamic properties in the quantum regime. It encompasses understanding protocols such as thermalization and out-of-equilibrium thermodynamics, as well as sampling from faithfully prepared ...

Influence of double solution treatment on hardness in 17-4 pH steel

open access: yesZaštita Materijala, 2015
The investigated material is a corrosion-resistant, Cu precipitation hardened steel 17-4PH, which undergoes a macroscopic contraction, as a result of applying the following heat treatment: double solution treatment at 1028°C for 1 h (condition A), ageing

An optimized TEM specimen preparation method of quantum nanostructures [PDF]

open access: yespublished 2020, 2022
Electron transparent TEM lamella with unaltered microstructure and chemistry is the prerequisite for successful TEM explorations. Currently, TEM specimen preparation of quantum nanostructures, such as quantum dots (QDs), remains a challenge. In this work, we optimize the sample-preparation routine for achieving high-quality TEM specimens consisting of ...

Nylon 6-cellulose composite hosted in a hypodermic needle: Biofluid extraction and analysis by ambient mass spectrometry in a single device

open access: yesJournal of Pharmaceutical Analysis, 2023
This study proposes a hypodermic needle (HN) as a sorbent holder and an electrospray (ESI) emitter, thus combining extraction and analysis in a single device. A novel nylon 6-cellulose (N6-Cel) composite sorbent is proposed to extract methadone from oral

New approach for FIB-preparation of atom probe specimens for aluminum alloys [PDF]

open access: yes, 2020
Site-specific atom probe tomography (APT) from aluminum alloys has been limited by sample preparation issues. Indeed, Ga, which is conventionally used in focused-ion beam (FIB) preparations, has a high affinity for Al grain boundaries and causes their embrittlement. This leads to high concentrations of Ga at grain boundaries after specimen preparation,

Paper-based sorptive phases for a sustainable sample preparation

open access: yesAdvances in Sample Preparation, 2023
In recent years, using natural materials to prepare sorbents has been a clear trend in the sample preparation context. This research line is supported by sustainable considerations, as it responds to the tenth principle of Green Analytical Chemistry ...
