Three-terminal semiconductor junction thermoelectric devices: improving performance

New Journal of Physics, 2013
A three-terminal thermoelectric device based on a p–i–n semiconductor junction is proposed, where the intrinsic region is mounted onto what is typically a bosonic thermal terminal.

Obesity Subtypes and Longitudinal Trajectories of Function Over Seven Years of Follow‐Up: Data From the Multicenter Osteoarthritis Study

Arthritis Care &Research, EarlyView.
Objective Obesity, defined by body mass index (BMI) ≥30 kg/m2, is a risk factor for functional limitations in people with knee osteoarthritis (OA). However, function varies among such individuals. Our objective was to evaluate the implications of obesity subtypes on longitudinal patterns of physical functioning in people with or at risk for knee OA ...

A simple figure of merit for high temperature superconducting switches [PDF]

, 1989
The discovery of the new high temperature superconductors has revived interest in many special applications, including superconducting switches. For comparison of switch types, a simple figure of merit based in switch performance is proposed, derived for

Immunosuppressive Drug Use in Limited Systemic Sclerosis: An International Survey

Arthritis Care &Research, EarlyView.
Objective Current guidelines recommend immunosuppressive treatment for diffuse cutaneous systemic sclerosis but are less clear on their use in limited cutaneous systemic sclerosis (lcSSc) in the absence of internal organ complications. We conducted an international survey to understand current immunosuppressive drug prescribing patterns in lcSSc ...

Patients improve, patterns persist: longitudinal stability of RA joint involvement patterns

Arthritis Care &Research, Accepted Article.
Objective Rheumatoid arthritis is a heterogeneous disease. Data‐driven approaches, from synovial histology to joint involvement patterns (JIPs), have sought to define clinically meaningful subgroups. Whether these subgroups represent stable phenotypes or transient disease states remains unclear.

Phase-dependent thermoelectric performance of MnIn2Te4

Materials & Design
We investigate the thermoelectric properties of MnIn2Te4 in both experimentally characterized phases. The tetragonal phase undergoes a pressure-induced transition to an orthorhombic phase at 1.3 GPa. First-principles calculations reveal for both phases a

Guided Mode Resonance Sensors with Optimized Figure of Merit

Nanomaterials, 2019
The guided mode resonance (GMR) effect is widely used in biosensing due to its advantages of narrow linewidth and high efficiency. However, the optimization of a figure of merit (FOM) has not been considered for most GMR sensors.

Revisiting Stability Criteria in Ball‐Milled High‐Entropy Alloys: Do Hume–Rothery and Thermodynamic Rules Equally Apply?

Advanced Engineering Materials, Volume 27, Issue 6, March 2025.
The stability criteria affecting the formation of high‐entropy alloys, particularly focusing in supersaturated solid solutions produced by mechanical alloying, are analyzed. Criteria based on Hume–Rothery rules are distinguished from those derived from thermodynamic relations. The formers are generally applicable to mechanically alloyed samples.

Ti4C3 and Ti4N3 MXenes: ultrafast Na-ion diffusion and figure-of-merit benchmarking for sodium-ion battery anodes

Materials Today Sustainability
Here, density functional theory calculations are used to evaluate Ti4C3 and Ti4N3 MXenes as sodium ion-battery (SIB) anodes. Both MXenes offer multiple energetically favorable Na adsorption sites with strong binding, supporting uniform Na accommodation ...
