Strain Development During Cure of Partially Pre‐Cured Thermosetting Composites Measured With Distributed Fiber Optic Sensors

open access: yesPolymer Composites, EarlyView.
Schematic representation of the beneficial effect of ply pre‐curing on temperature overshoot, internal strain and warpage during cure of thin and thick thermosetting composites. ABSTRACT Detection of manufacturing‐induced defects in thermosetting composites is crucial to guarantee part quality, safety, and improve manufacturing efficiency.

Impact of moisture gradients on ultrasonic evaluation of concrete and mortar blocks subjected to thermal exposures

open access: yese-Journal of Nondestructive Testing
Non-destructive evaluation (NDE) of concrete has significantly advanced, providing valuable insights into material properties. While the sensitivities of various NDE methods conducted in concrete to damages and environmental conditions are well ...

Moist convection and radiative cooling: Dynamical response and scaling

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
The mechanism that sets the updraught velocities in deep convective clouds is studied here using cloud‐resolving model simulations in radiative–convective equilibrium. We show that, for simulations with vastly different rates of radiative cooling and surface temperatures, the buoyancy in clouds remains remarkably constant (histogram shown here).

Probing microcavity polariton superfluidity through resonant Rayleigh scattering

open access: yes, 2004
We investigate the two-dimensional motion of polaritons injected into a planar microcavity by a continuous wave optical pump in presence of a static perturbation, e.g. a point defect.

When tiny convective spread affects a midlatitude jet: Spread sequence

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
We investigate spread evolution by mesoscale convection from tiny initial condition uncertainty during a real event. There is significant variation among the systems in their propensity to interact with the jet stream, whereby variability in one system (due to convective and long‐wave radiative heating tendencies) tightly relates to Rossby‐like ...

Unravelling Electronic Structure and Molecular Vibrations of Proteins in Virus Using Novel Correlated Plasmon‐Enhanced Raman Spectroscopy With Machine Learning

open access: yesSmall, EarlyView.
A novel, non‐destructive, stable, direct technique, named correlated plasmon‐enhanced Raman spectroscopy (CP‐ERS), which is based on a newly‐developed highly oriented single crystalline gold quantum dots (HOSG‐QDs) chip, is developed to measure and quantify molecular vibrations and electronic structure of analytes.

Tomography S Velocity Structure between Washington’s Earthquake C022801l and Observational Station Tuc through Seismogram Analysis

open access: yesMakara Seri Sains, 2005
In this research the S speed structure is investigated by seismogram analysis of Washington's earthquake, C022801L using data of TUC station, Tucson, Arizona, U.S.A. The seismogram comparison between the observed and the synthetic seismogram is conducted

Ultrathin Freestanding MoSiN Nanocomposite Membranes as Efficient High‐Temperature Mid‐Infrared Thermal Emitters

open access: yesSmall, EarlyView.
Ultrathin freestanding MoSiN nanocomposite membranes are developed as stable and efficient mid‐infrared emitters for gas sensing under extreme thermal conditions. A 12 nm‐thick membrane combines intermetallic phases for enhanced IR absorption with a dielectric phase for mechanical stability.
