Pressure Engineering Promising Transparent Oxides with Large Conductivity Enhancement and Strong Thermal Stability

open access: yesAdvanced Science, 2022
Transparent conducting oxides (TCO) with high electrical conductivity and high visible light transparency are desired for a wide range of high‐impact engineering. Yet, usually, a compromise must be made between conductivity and transparency, limiting the

Band gap closure, incommensurability and molecular dissociation of dense chlorine

open access: yesNature Communications, 2019
Molecular systems are predicted to transform into atomic solids and be metallic at high pressure; this was observed for the diatomic elements iodine and bromine. Here the authors access the higher pressures needed to observe the dissociation in chlorine,

Formation of an Al‐Rich Niccolite‐Type Silica in Subducted Oceanic Crust: Implications for Water Transport to the Deep Lower Mantle

open access: yesGeophysical Research Letters, 2022
Subducted oceanic crust is enriched in free silica. Although being one of the silica polymorphs at lower‐mantle pressures, niccolite‐type phase (Nt‐phase) has not been documented in multicomponent metabasaltic or metasediment compositions relevant to ...

Author Correction: Band gap closure, incommensurability and molecular dissociation of dense chlorine

open access: yesNature Communications, 2019
The original version of this Article omitted references to previous experimental reports on solid hydrogen that are relevant for a full understanding of the context of the previous work. The added references are: 47. Akahama, Y. et al.

Structural transitions of 4:1 methanol–ethanol mixture and silicone oil under high pressure

open access: yesMatter and Radiation at Extremes, 2021
A 4:1 (volume ratio) methanol–ethanol (ME) mixture and silicone oil are two of the most widely used liquid pressure-transmitting media (PTM) in high-pressure studies.

A Velostat-Based Pressure-Sensitive Mat for Center-of-Pressure Measurements: A Preliminary Study [PDF]

open access: yesInternational Journal of Environmental Research and Public Health, 2021
Center-of-pressure (CoP) displacements play a key role in studies assessing postural stability. The accepted instrument to measure CoP trajectories is the force platform, but pressure-sensitive mats (PSMs) are an alternative composed of a matrix of sensitive cells. A typical cell comprises two electrodes with piezoresistive material in between, while a

Center of pressure based segment inertial parameters validation

open access: yesPLOS ONE, 2017
By proposing efficient methods for estimating Body Segment Inertial Parameters' (BSIP) estimation and validating them with a force plate, it is possible to improve the inverse dynamic computations that are necessary in multiple research areas. Until today a variety of studies have been conducted to improve BSIP estimation but to our knowledge a real ...

Yolk–shell nanoarchitecture for stabilizing a Ce2S3 anode

open access: yesCarbon Energy, 2021
Rare‐earth sulfides are of research interest for lithium‐ion batteries (LIBs) due to their abundant lithium intercalation sites and low redox voltage.

Toughening of silicon nitride ceramics through stress-induced phase transformation

open access: yesJournal of Advanced Ceramics
Ceramics, particularly covalently bonded ceramics, exhibit intrinsic brittleness resulting from the strong directional nature of their chemical bonds, significantly limiting their applications.

In situ high-pressure spectroscopic studies using moissanite (4H-SiC) anvils

open access: yesAIP Advances, 2018
We examined the Raman scattering and IR absorption spectroscopy of 4H-SiC and its performance as an anvil material for high-pressure UV-visible absorption spectroscopic measurements.
