Sonicated Carbon Nanotube Catalysts for Efficient Point‐of‐use Water Treatment

Advanced Materials, EarlyView.
The growing demand for freshwater and rising contamination of water sources require innovative treatment technologies. Sonicated carbon nanotubes can activate persulfate for selective contaminant degradation via nonradical pathways. This scalable approach enables rapid pollutant removal, offering a sustainable solution for decentralized freshwater ...

Codeword Stabilized Quantum Codes for Asymmetric Channels [PDF]

, 2016
We discuss a method to adapt the codeword stabilized (CWS) quantum code framework to the problem of finding asymmetric quantum codes. We focus on the corresponding Pauli error models for amplitude damping noise and phase damping noise. In particular, we look at codes for Pauli error models that correct one or two amplitude damping errors.

Ultrathin Mesoporous Metal‐Organic Framework Nanosheets

Advanced Materials, EarlyView.
A bottom‐up interface‐directed co‐assembly strategy enables the synthesis of ultrathin 2D mesoporous UiO‐66(Ce) nanosheets with tunable thickness and uniform mesopores. The enhanced mass transport and accessible active sites significantly improve performance, highlighting the synergistic effects of 2D morphology and mesopores in metal‐organic ...

Experimental and numerical investigation of blade resonance in a centrifugal compressor for varying gas properties

Journal of the Global Power and Propulsion Society, 2018
The blades of centrifugal compressors are exposed to unsteady forces during operation which can result in resonance response conditions and failures due to high cycle fatigue.

Understanding the Role of Copper Oxidation State on a TiO2/ZSM‐5 Catalyst for Photocatalytic CO2 Reduction to Methanol

Advanced Materials Interfaces, EarlyView.
The influence of copper oxidation states on TiO₂/ZSM‐5 catalysts is investigated for photocatalytic CO2 reduction to methanol. A Cuδ⁺‐modified Ti₂/ZSM‐5 catalyst (CTZ‐1) exhibits superior activity due to enhanced electronhole separation, the presence of Ti3⁺, and a core–shell structure.

High-fidelity quantum teleportation through noisy channels via weak measurement and environment-assisted measurement

Results in Physics, 2023
A perfect teleportation protocol requires pure maximally shared entangled states. While in reality the shared entanglement is drastically degraded due to the inevitable interaction with the noisy environment.

Which verification qubits perform best for secure communication in noisy channel?

, 2015
In secure quantum communication protocols, a set of single qubits prepared using 2 or more mutually unbiased bases or a set of $n$-qubit ($n\geq2$) entangled states of a particular form are usually used to form a verification string which is subsequently

Piezoelectric Polyurethane/Barium Titanate Composites with High Stretchability and Voltage Output for Energy Harvesting in Soft Wearable Electronics

Advanced Materials Technologies, EarlyView.
Piezoelectric additives are combined with an elastomer host, creating a material with properties of both parent materials: high voltage output and exceptional stretchability. These stretchable piezoelectric materials have the robustness for integration into soft wearable electronics, functioning as renewable energy harvesters to charge capacitors.

Versatile relative entropy bounds for quantum networks

New Journal of Physics, 2018
We provide a versatile upper bound on the number of maximally entangled qubits, or private bits, shared by two parties via a generic adaptive communication protocol over a quantum network when the use of classical communication is not restricted ...

Evolution equation of entanglement for multi-qubit systems

, 2010
We discuss entanglement evolution of a multi-qubit system when one of its qubits is subjected to a general noisy channel. For such a system, an evolution equation of entanglement for a lower bound for multi-qubit concurrence is derived.
