Atomic Layer Deposited Cu Incorporation Enables Enhanced Thermoelectric Performance in n‐Type Mg3(Sb, Bi)2

Small Structures, Volume 7, Issue 3, March 2026.
A metallic Cu powder atomic layer deposition (pALD) strategy is developed to engineer particle‐boundary interfaces in n‐type Mg3(Sb, Bi)2. Cu‐induced grain growth and compensation of Mg deficiencies at particle boundaries, enhance carrier mobility, while Cu‐rich boundary domains introduce additional phonon scattering.

Derjaguin’s Water II: a surface hydration phenomenon

Substantia, 2019
B.V. Derjaguin’s promotion of anomalous water II (polywater) in the early 1970s was an embarrassing point in the career of an illustrious chemist, and quickly repudiated by Derjaguin himself. Water II does not exist as a bulk liquid.

Processes Driving Drift‐Ice Evolution and Its Interaction With the Oceanic and Atmospheric Boundary Layers

Reviews of Geophysics, Volume 64, Issue 1, March 2026.
Abstract Sea ice is a crucial component of polar climate systems and is undergoing substantial changes in both hemispheres due to evolving climatic conditions. Arctic sea ice is transitioning from perennial to seasonal cover, and the Southern Ocean sea ice is exhibiting recent minima and enhanced seasonality.

Continuum dynamics and the electromagnetic field in the scalar ether theory of gravitation

Open Physics, 2016
An alternative, scalar theory of gravitation has been proposed, based on a mechanism/interpretation of gravity as being a pressure force: Archimedes’ thrust.

Characterizing Ion‐Scale Fluctuations Around Dipolarization Fronts in Earth's Magnetotail

Journal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract In the Earth's magnetotail bursty bulk flows are often associated with dipolarizing magnetic flux bundles. The leading edges of such earthward‐moving flux bundles are called dipolarization fronts (DF). In the present study we investigate the characteristics of ion‐scale oscillations embedded inside DFs, using observations from NASA's ...

Fabrication of a Plate-Type Porous Stainless Steel 316L Powder Filter with Different Pore Structures without Use of a Binder [PDF]

Archives of Metallurgy and Materials
Generally, when fabricating porous filters using metal powder, about 1 to 2 wt% of a binder is added to increase the formability of the metal powder. If the binder is not completely removed through a debinding and sintering process, however it can cause ...

Performance Enhancement of Ca3Co4O9‐based Transverse Multilayer Thermoelectric Generators for Low‐Power Applications

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
Transverse multilayer thermoelectric generators (TMLTEGs) were fabricated using Ca3Co4O9 and Ag. Optimum geometry of the TMLTEGs was determined by numerical calculations and simulation. Power output is enhanced by 80% through layer thickness optimization.

Effect of Ce/La Substitution on Optical Transparency and Ionic Conductivity of Sodium Silicate Glasses

Journal of the American Ceramic Society, Volume 109, Issue 3, March 2026.
ABSTRACT We investigate sodium silicate glasses modified with Ce2O3 and La2O3 to explore the interplay between optical absorption, structure, and macroscopic properties. Ce doping drives a pronounced red‐shift of the absorption edge into the visible region (> 500 nm), arising from O2− →$ \to $ Ce4+ charge‐transfer and intervalence transitions ...

Fluidity evaluation of fiber reinforced-self compacting concrete based on buoyancy law

HBRC Journal, 2018
An experimental testing program was undertaken to evaluate the applicability of using the principles of Archimedes' law for buoyancy to assess the fluidity of self compacting concrete (SCC) as well as fiber reinforced self compacting concrete mixes (FR ...
