Magnetic Force‐Induced Self‐Assembly and Flip‐Chip Alignment on Electroplated Multilayer Solder with Tailored Melting Points

open access: yesAdvanced Materials Technologies, EarlyView.
This work demonstrates fluidic self‐assembly and self‐alignment of flip‐chips using a magnetic field for agitation and orientation. Pb‐free solder bumps with tailored transformation imprinted melting points enable selective capturing on low‐melting solder in water. After capturing, final alignment is achieved through magnetic forces.

Thermoelectricity of EuCu{2}(Ge{1-x}Si{x}){2} intermetallics [PDF]

open access: yes, 2005
The evolution of the thermopower EuCu{2}(Ge{1-x}Si{x}){2} intermetallics, which is induced by the Si-Ge substitution, is explained by the Kondo scattering of conduction electrons on the Eu ions which fluctuate between the magnetic 2+ and non-magnetic 3+ Hund's rule configurations. The Si-Ge substitution is equivalent to chemical pressure which modifies

High‐Entropy Alloys and Oxides as Supercapacitor Electrodes: A Structural and Electrochemical Perspective for Energy Storage

open access: yesAdvanced Sustainable Systems, EarlyView.
This study compares the electrochemical performance of high‐entropy alloys (HEA) and oxides (HEO) as supercapacitor electrodes. HEO demonstrates superior energy and power density due to its capacitive behavior and surface redox reactions, while HEA relies on diffusion‐controlled processes.

Mitigating Strain Localization via Stabilized Phase Boundaries for Strengthening Multi‐Principal Element Alloys

open access: yesAdvanced Science, EarlyView.
Strain localization along phase or grain boundaries leads to crack initiation typical of alloys. In multi‐principal element alloys, the enamel‐like microstructure is stabilized by phase boundaries. This facilitates trans‐phase migration of semi‐atomic surfaces and provides sufficient plastic space for dislocation‐mediated deformation.

UV‐induced degradation of high‐efficiency silicon PV modules with different cell architectures

open access: yesProgress in Photovoltaics: Research and Applications, Volume 31, Issue 1, Page 36-51, January 2023., 2023
The use of UV‐pass encapsulants in PV modules is becoming a popular option to capture ~1% light gain; however, this makes the cells more susceptible to ultraviolet‐induced degradation. In this study, modern crystalline‐silicon PV technologies including HJ, IBC, PERT, and PERC cells have shown greater power degradation when exposed to UV as compared ...

Dynamic Ionic Environment Modulation for Precise Electrosynthesis of Heterostructured Bimetallic Nanoparticles

open access: yesAdvanced Science, EarlyView.
An electrosynthesis method is introduced for fabricating heterostructured bimetallic nanoparticles, providing precise and independent control over elemental distribution within individual nanostructures. By dynamically modulating the ionic environment in a dual‐channel nanopipette using scanning electrochemical cell microscopy, core–shell nanoparticles

Effect of Chromium and Molybdenum Increment on the Crystal Structure, Nanoindentation, and Corrosion Properties of Cobalt‐Based Alloys

open access: yesphysica status solidi (a), Volume 219, Issue 23, December 2022., 2022
This study deals with the microstructural, nanoindentation and corrosion properties of the cobalt–chromium–molybdenum alloy system. Hardness increases linearly as a function of chromium, while reduced modulus shows maximum for Co30Cr5Mo and Co25Cr10Mo, respectively.
