Octahedral oxide glass network in ambient pressure neodymium titanate

Scientific Reports, 2022
Rare-earth titanates form very fragile liquids that can be made into glasses with useful optical properties. We investigate the atomic structure of 83TiO2-17Nd2O3 glass using pair distribution function (PDF) analysis of X-ray and neutron diffraction with

Conceptual Design of the Moderator Test Station at the Spallation Neutron Source [PDF]

EPJ Web of Conferences
We describe the Moderator Test Station (MTS), under construction at the Spallation Neutron Source. We will leverage the Beam Test Facility (BTF) at the Spallation Neutron Source to provide a moderator neutronics test stand with which we will verify the ...

Real electronic signal data from particle accelerator power systems for machine learning anomaly detection

Data in Brief, 2022
This article describes real time series datasets collected from the high voltage converter modulators (HVCM) of the Spallation Neutron Source facility. HVCMs are used to power the linear accelerator klystrons, which in turn produce the high-power radio ...

A Fast-neutron Source for Radiotherapy [PDF]

Nature, 1963
IN a recent note, Lomer and Greene1 have recommended the development of a 14-MeV fast-neutron source for radiotherapy. We feel that there are disadvantages to this approach. The relative biological effectiveness of fast neutrons is related to their linear energy transfer, which in turn varies inversely with the energy of the neutron2,3.

Implementing bubbly mercury material model (R-P model) in the pulse simulation to predict strain on the Spallation Neutron Source target vessel with gas injection

Results in Physics, 2023
The Spallation Neutron Source (SNS) creates neutrons by striking a liquid mercury target with short pulses of high-energy protons. SNS targets have been operated with helium microbubble gas injection into portions of the flowing mercury since 2017.

Application and Development of Tumor-Targeting Boron Carriers in Boron Neutron Capture Therapy

He huaxue yu fangshe huaxue, 2023
Boron neutron capture therapy(BNCT) is a promising therapeutic method for malignant tumors and has entered the clinical trials. As a binary cellular accurate therapy, BNCT relies on tumor-targeting boron delivery.

Multiscale characterization reveals oligomerization dependent phase separation of primer-independent RNA polymerase nsp8 from SARS-CoV-2

Communications Biology, 2022
The phase separation behaviour of non-structure protein nsp8 of SARS CoV2 in the primer synthesis mechanism is presented, underpinning the replication of coronavirus.

Sensing Performance of Ethanol Microfiber Probe Augmented by ZnO Nanosheet and UV Glue Film

Photonics, 2023
A microfiber reflective ethanol gas sensing probe was designed and fabricated. The single-mode fiber was heated and stretched to prepare a microfiber taper, on which a mixed material of ZnO nanosheets and UV glue was built by the dip-coating method.
