Dual-band switchable terahertz metamaterial absorber based on metal nanostructure

open access: yesResults in Physics, 2019
In this paper, a tunable terahertz metamaterial absorber with two bands is proposed. It is composed of Au reflector, dielectric layer and periodic array of Au. By adjusting different materials and optimizing parameters, it can achieve the characteristics

Tailoring electronic properties [PDF]

open access: yesScience, 2020
Physics The layered material α-RuCl3 has piqued the interest of physicists as a potential platform for the so-called Kitaev model—a type of quantum spin liquid that hosts exotic excitations. However, in addition to the magnetic interactions of the Kitaev model, α-RuCl3 also hosts non-Kitaev interactions. Biswas et al. investigated theoretically whether

Glutarimides: Biological activity, general synthetic methods and physicochemical properties [PDF]

open access: yesHemijska Industrija, 2015
Glutarimides, 2,6-dioxopiperidines are compounds that rarely occur in natural sources, but so far isolated ones exert widespread pharmacological activities, which makes them valuable as potential pharmacotherapeutics.

Structure and Properties of ZnSnP2 With the Application in Photovoltaic Devices by Using CdS and ZnTe Buffer Layers

open access: yesEast European Journal of Physics, 2021
Ab initio calculations have been performed by the linearized augmented plane wave (LAPW) method as implemented in the WIEN2K code within the density functional theory to obtain the structural, electronic and optical properties of ZnSnP2 in the body ...

Theoretical design of a triple-band perfect metamaterial absorber in the THz frequency range

open access: yesResults in Physics, 2019
A triple-band perfect metamaterial absorber based on periodically arranged graphene split ring resonator (SRR) is proposed in this study. The calculation results by the FDTD method indicate that the SRR structure has three absorption peaks at frequencies

Endohedral Functionalization of Metallicity-Sorted Single-Walled Carbon Nanotubes

open access: yesProceedings, 2020
We performed endohedral functionalization of high-purity metallicity-sorted semiconducting and metallic single-walled carbon nanotubes (SWCNTs) with a mean diameter of 1.4 nm with silver chloride (AgCl) by the method of capillary filling with the melt ...

Influence of f Electrons on the Electronic Band Structure of Rare-Earth Nickelates

open access: yesCondensed Matter, 2023
Recently, superconductivity was discovered in the infinite layer of hole-doped nickelates NdNiO2. Contrary to this, superconductivity in LaNiO2 is still under debate.

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

open access: yesPediatric 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.

Stability of FeVO4-II under Pressure: A First-Principles Study

open access: yesCrystals, 2022
In this work, we report first-principles calculations to study FeVO4 in the CrVO4-type (phase II) structure under pressure. Total-energy calculations were performed in order to analyze the structural parameters, the electronic, elastic, mechanical, and ...

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

open access: yesPediatric 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 ...
