Volumetric Density Capture From a Single Image
, 2008 We propose a new approach to capture the volumetric density of scattering media instantaneously with a single image. The volume is probed with a set of laser lines and the scattered intensity is recorded by a conventional camera.

Validation of Models to describe Local Transport Phenomena in Bubble Columns [PDF]
, 2013 The purpose of this master thesis is to analyze existing models of gas hold-up and volumetric mass transfer. After extensive literature research, the models are quantitatively and qualitatively compared, underlining whether important aspects are ...

Bistable Isochoric Chiral Metamaterials with Reprogrammable Multiaxial Responses
Advanced Functional Materials, EarlyView.An isochoric bistable rotational unit cell enables in situ modification of internal contact conditions post‐fabrication, without altering the global envelope dimensions of the surrounding architecture. By selectively switching between open and closed states, the tessellated chiral metamaterial can reprogram its volumetric response, including bulk ...

, 2014 Mammographic density, the white radiolucent part of a mammogram, is a marker of breast cancer risk and mammographic sensitivity. There are several means of measuring mammographic density, among which are area-based and volumetric-based approaches ...

Tantalum–Palladium Ultrathin Resistance Hydrogen Sensor
Advanced Functional Materials, EarlyView.Nanoconfined Ta‐alloy thin films enable fast, reversible hydrogen sensing by suppressing unwanted phase transitions. A Ta0.88${\rm Ta}_{0.88}$Pd0.12${\rm Pd}_{0.12}$ sensing layer delivers hysteresis‐free detection from ppb to 100% H2${\rm H}_2$ at room temperature.

Dysmotility in Thyroid Eye Disease: Volumetric and Density Analysis
, 2023 Thyroid eye disease (TED) is often characterized by enlargement of extraocular muscles (EOM) and orbital fat, causing proptosis and EOM dysmotility. Previous studies have investigated dysmotility and EOM size based on measurements of EOM diameter.[1] We ...

Advanced Functional Materials, EarlyView.Neuromorphic plasticity in OECTs is governed by the post‐stimulus evolution of coupled ionic and electronic states. Semiconductor chemistry and morphology, electrolyte composition and interfaces, and device architecture regulate ion injection, transport, confinement, and release, shifting responses from rapidly relaxing STP to metastable memory and ...

Advanced Functional Materials, EarlyView.Spatially distributing Ti3C2Tx nanosheets into core‐shell architecture, rather than as directly dispersed flakes, mitigates aggregation and enhances photon harvesting. When the Ti3C2Tx core‐shell particles are incorporated into a shape‐memory polymer matrix at an ultralow loading of 0.0024 wt%, the improved photothermal conversion translates into ...
