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.

Measurement method for T-h properties of phase change material

Journal of Asian Architecture and Building Engineering, 2023
In this study, a simple and inexpensive T-h property measurement method was proposed for measuring the temperature and specific enthalpy of a flat plate phase change material (PCM) by cooling and heating it under adiabatic conditions on one side and ...

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 ...

All-optical non-volatile tuning of an AMZI-coupled ring resonator with GST phase-change material [PDF]

, 2018
We present a Ge2Sb2Te5 (GST)-integrated ring resonator with the tuning enabled by an all-optical phase change of GST using a sequence of optical pulses. The tuning is non-volatile and repeatable, with no static power consumption due to the “self-holding”

Unheard and Under‐Supported: Health‐Related Quality of Life in Children, Adolescents, and Young Adults With Sickle Cell Disease

Pediatric Blood &Cancer, EarlyView.
Abstract Background Sickle cell disease (SCD) is an autosomal recessive hemoglobinopathy affecting millions of individuals worldwide. The clinical expression and psychosocial burden of SCD vary widely across geographical, cultural, and healthcare system contexts, underscoring the need for setting‐specific approaches to assessment.

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

Imaging of High‐Risk Neuroblastoma: Recommendations From SIOPEN Radiology and Nuclear Medicine Specialty Committees

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Neuroblastoma is the most common extracranial solid tumor in early childhood. Its clinical behavior is highly variable, ranging from spontaneous regression to fatal outcome despite intensive treatment. The International Society of Pediatric Oncology Europe Neuroblastoma Group (SIOPEN) Radiology and Nuclear Medicine Specialty Committees ...

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 ...
