High Thermoelectric Performance Achieved by Manipulating the Band Structure and Lattice Dislocations in n‐Type Ge/Pb/Br Codoped Polycrystalline SnSe

open access: yesCarbon Energy, EarlyView.
Pb/Ge/Br codoping in n‐type polycrystalline SnSe induces band convergence and high‐density dislocations, yielding a high power factor of 7.47 μW cm−1 K−2 and ultralow lattice thermal conductivity. Consequently, a peak ZT of 1.6 is achieved, overcoming the traditional performance limitations of n‐type SnSe.

What buoyancy really is. A Generalized Archimedes Principle for sedimentation and ultracentrifugation [PDF]

open access: yes, 2012
Particle settling is a pervasive process in nature, and centrifugation is a versatile separation technique. Yet, the results of settling and ultracentrifugation experiments often appear to contradict the very law on which they are based: Archimedes ...

An assessment of stress and production rate of sucker rod heat pipes in oil well pumping system

open access: yesDeep Underground Science and Engineering, EarlyView.
The sucker rod pumping system is the preferred oil extraction technique. The concept about equipping the hollow vacuum space in solid sucker rods with heat pipe has been scrutinized in terms of stress and oil production evaluation. Abstract The implementation of the heat pipe concept in sucker rods for oil pumping systems negates the requirement for an

On the Conservatisms of Nepheline Predictors for Canister Centerline Cooled (CCC) High‐Level Waste (HLW) Glasses

open access: yesInternational Journal of Applied Glass Science, Volume 17, Issue 3, July 2026.
ABSTRACT Multiple models and feature sets have been generated, which attempt to predict the crystallization of nepheline (NaAlSiO4) in high‐level radioactive waste (HLW) glasses under canister centerline cooling (CCC) conditions. Earlier models were found to be overly conservative, while newer models had a not insignificant rate of false positives and ...
