Ultrafast changes in lattice symmetry probed by coherent phonons

, 2012
The electronic and structural properties of a material are strongly determined by its symmetry. Changing the symmetry via a photoinduced phase transition offers new ways to manipulate material properties on ultrafast timescales.

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Structure optimization of a phase change material integrated solar air collector/storage unit based upon phase change analysis

Energy Reports, 2021
A phase change material (PCM) integrated solar air collector/storage unit (SACSU) for mid-temperature applications was proposed in the study. The composite PCM with expanded graphite (EG) in mass fraction of 3% was prepared to enhance the thermal ...

Preferences of Pediatric Patients and Their Caregivers for Chemotherapy‐Induced Nausea and Vomiting Control Endpoints: A Mixed Methods Study

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Purpose Although not always achieved, complete chemotherapy‐induced nausea and vomiting (CINV) control is the conventional goal of CINV prophylaxis. In this two‐center, mixed‐methods study, we sought to understand the preferences of adolescent patients and family caregivers for CINV control endpoints.

Broadband Reflective Optical Limiter Using GST Phase Change Material

IEEE Photonics Journal, 2018
We experimentally demonstrate a thermally induced reflective optical limiter using Ge $_2$Sb$_2$ Te$_5$ (GST) and SiO $_2$ in a multilayer photonic bandgap edge-filter configuration. In the PASS state, greater than 80% transmission was achieved at

Prevalence and Trajectory of Household Material Hardship Among Children With Advanced Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background/Objectives Families of children with advanced cancer living in poverty experience inferior outcomes including poor parent mental health and worse child quality of life. Household material hardship (HMH: food, housing, transportation, and/or utility insecurity) is a modifiable poverty exposure—and potential intervention target—that ...

Thermal Irreversibility in Nano-Enhanced Phase Change Material Liquefaction

Fluids
Inside a closed, thin-walled hollow cylinder, there is a solid state of phase change material (NePCM) that has been nano-enhanced. This NePCM is heated at its bottom, with nanoparticles (Al2O3) inserted and homogenized within the PCM (sodium acetate ...

Phase Change Material in Glazing Windows System: A Review [PDF]

Engineering and Technology Journal
As far as thermal insulation is concerned, phase change materials (PCM) have a very good potential to be excellent insulation materials due to their thermal properties like low thermal conductivity and high latent heat.
