Thermal performance of nanoencapsulated phase change ...

Phase change materials are classified into two main categories, organic and inorganic. Most of the organic PCMs have low thermal conductivity and poor thermal response as well as being flammable, however, these limitations may be overcome by employing encapsulation technologies [1].

Encapsulation of Phase Change Materials Using Layer-by ...

Phase change materials absorb the thermal energy when changing their phases (e.g., solid-to-liquid) at constant temperatures to achieve the latent heat storage. The major drawbacks such as limited thermal conductivity and leakage prevent the PCMs from wide application in desired areas. In this work, an environmentally friendly and low cost approach, layer-by-layer (LbL) assembly technique, was ...

Magnetic Weyl semimetal phase in a Kagomé crystal | Science

Sep 20, 2019· Weyl semimetals (WSMs)—materials that host exotic quasiparticles called Weyl fermions—must break either spatial inversion or time-reversal symmetry. A number of WSMs that break inversion symmetry have been identified, but showing unambiguously that a material is a time-reversal-breaking WSM is tricky. Three groups now provide spectroscopic evidence for this latter state in …

Manipulating polarization, phase, and amplitude simultaneously in real time is an ultimate pursuit of controlling light. Several types of controllable metasurfaces have been realized, but with either low transmission efficiencies or limited control over amplitude, polarization, and phase in real time. Here we present a weak oscillation theory dealing with a new, to the best of our knowledge ...

Tunable/Reconfigurable Metasurfaces: Physics and Applications

Light-induced phase-change materials (PCMs) [39–42, 102–107] were another class of candidates to realize OTMs. In 2012, D. Averitt and coworkers experimentally demonstrated a dynamical modulation on THz transmission (with modulation depth of ~38% at 0.41 THz) through a metasurface with vanadium dioxide (VO 2 ) incorporated (see Figure 3 (d)).

Bulk Grain-Boundary Materials from Nanocrystals: Chem

We propose a new concept, the nanocrystal (NC)-coining process, to produce bulk materials with precisely tailored nanoscale grain-boundary conditions. By consolidating surface-engineered NCs into bulk materials using pressure, we can fabricate free-standing NC coins with metallic appearance and conductivity, while preserving the original NC domain feature.

A key issue in fabricating transistors is making a good electrical contact to the semiconductor gate material. For two-dimensional materials, one route is through a phase transition that converts a hexagonally packed semiconductor phase into a distorted octahedrally packed metallic phase. Cho et al. show that laser heating of molybdenum telluride (MoTe2) achieves this conversion through the ...
