Optical Phonon Decay and Improved Thermoelectric Efficiency in p-Type MgSb.

The MgSb-based layered compounds exhibit exceptional thermoelectric properties over a wide temperature range and possess the potential to supplant traditional BiTe modules with reliable and economical MgSb-based thermoelectric devices, contingent upon the availability of a complementary p-type MgSb material with high thermoelectric efficiency comparable to that of n-type MgSb. We provide a simpler method involving the codoping of monovalent atoms (K and Na) at the Mg site of the MgSb lattice to improve the thermoelectric performance of p-type MgSb. K-Na codoping results in a peak power factor of around 0.

Flexible AgSe Film with Enhanced Thermoelectric Performance.

Flexible thermoelectric devices offer huge potential for wearable electronics due to their ability to generate green energy by using low-grade heat. However, achieving both high thermoelectric performance and flexibility simultaneously remains a challenge for these devices. Here, we present a simple and cost-effective method for fabricating a high-performance flexible inorganic-organic thermoelectric film by depositing AgSe on a porous nylon membrane.

A comparison of clinical and radiological outcomes following laminectomy and laminectomy with fusion in patients of cervical spondylotic myelopathy: A systematic review and meta-analysis.

To conduct a systematic review and meta-analysis comparing the functional and radiological outcomes in cervical spondylotic myelopathy (CSM) when treated by Laminectomy (LC) vs. laminectomy with instrumented fusion (LCF). The systematic review was conducted in accordance with PRISMA guidelines.

Water vapor responsiveness of chitosan: An experimental and simulation analysis.

Stimuli-responsive polymers have gained significant research interest in recent years owing to their potential applications in diverse areas. Here, we present a study on the actuation characteristics of chitosan-based free-standing films that exhibit full reversibility and repeatability in response to water vapor exposure. The effect of pH of the water and the degree of cross-linking of the chitosan films on the actuation performance is studied.

Polymer-Mediated Crack Suppression in Deposit of Nanoellipsoids.

Uniform distribution of particles and crack suppression in dried particulate deposits are major challenges for applications in coating and printing technologies. To address this, we investigated the impact of the addition of a water-soluble polymer, poly(vinyl alcohol) (PVA), on the evaporative self-assembly and kinetics of crack formation in deposits of anisotropic colloids. The fluid flow inside the drying drop is significantly altered due to polymer-mediated adsorption of ellipsoids to the drop surface.
