Synchrotron Radiation for Quantum Technology

open access: yesAdvanced Functional Materials, EarlyView.
Materials and interfaces underpin quantum technologies, with synchrotron and FEL methods key to understanding and optimizing them. Advances span superconducting and semiconducting qubits, 2D materials, and topological systems, where strain, defects, and interfaces govern performance.

Photoactivation of NV Centers in Diamond via Continuous Wave Laser Illumination of Shallow As‐Implanted Nitrogen

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates an alternative method of creating charge‐stable negatively charged nitrogen vacancy (NV−) centers close to the diamond surface without high‐temperature annealing. By illuminating nitrogen‐implanted regions with a continuous‐wave 405 nm laser, NV− centers are induced, exhibiting electron spin coherence properties suitable for ...

Molecular characterization of polar organosulfates in secondary organic aerosol from the green leaf volatile 3-Z-hexenal [PDF]

open access: yes, 2014
Evidence is provided That the green leaf volatiles 3-Z- hexenal serves as a precursor for biogenic secondary organic aersol through the formation of polar organosulfates (Os) with molecular weight (MW) 226.

Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

open access: yesAdvanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Air purification by hypochlorous acid gas [PDF]

open access: yesJournal of Hygiene, 1941
1. A short synopsis of research upon application of hypochlorites to airpurification is given.2. A short review of the most recent work on this subject shows that:(a) Of the “nebulizers” employed by Baker, Finn & Twort (1940) the “Atmozon” is incapable of consistent atomizing of hypochlorites, whilst the “Aerograph” has an efficiency much below ...

Evaluation of distributed gas cooling of pressurized PAFC for utility power generation [PDF]

open access: yes
A proof-of-concept test for a gas-cooled pressurized phosphoric acid fuel cell is described. After initial feasibility studies in short stacks, two 10 kW stacks are tested.
