Flip‐Chip Integration of the Superconducting Quantum‐Classical Circuits: Coupling Types

open access: yesAdvanced Quantum Technologies, EarlyView.
This article explores the use of 3D modular architectures with flip‐chip technology to overcome scalability challenges in superconducting quantum processors. Based onλ/4 and λ/2 resonators, the article systematically analyzes capacitive, inductive, and galvanic interconnects.

Superior Carbon Nanotube Field Emission for X‐Ray Source via Metal Silicide‐Induced Adhesion

open access: yesSmall, EarlyView.
The adhesion of CNT field emitters (FEs) is enhanced using Ni and Si fillers, which formed strong bonding phases (Ni₂Si and Fe₂NiSi) in the paste and Kovar substrate during high‐temperature annealing. CNT FEs containing both fillers exhibit superior adhesion and outperform those with a single filler, achieving a high emission current density (30.9 A cm−

Bimetallic Tandem Strategy for Effective Modulation of CO2 Electrocatalytic Selectivity on Relatively Inert Cu Interfaces

open access: yesSmall, EarlyView.
Bimetallic tandem interfaces of Cu‐M (M = Au, Ag, Pd) are constructed on Cu nanocolumn arrays with exposed Cu (200) facets to enhance CO2 reduction reaction (CO2RR) performance. In situ, spectroscopic analysis revealed specific reaction pathways for each interface. Abstract The development of effective strategies to enhance the activity and selectivity

Reactive Nanoparticle Composed Bilayers: An Alternate Route Toward the Production of Pt/Al Nanofoils

open access: yesSmall, EarlyView.
Spark ablation‐assisted gas phase electrodeposition is an alternate route toward Pt/Al self‐propagation reactive system synthesis. Pt film morphology‐dependent reaction kinetics is a significant advantage. Low spark power and gas flow rate produce porous films and slow speeds, while high power and flow rate give three orders of magnitude faster ...

Configuring a Liquid State High‐Entropy Metal Alloy Electrocatalyst

open access: yesSmall, EarlyView.
A liquid‐state high‐entropy metal alloy is developed to overcome key kinetic bottlenecks in ammonia electrosynthesis from nitrate. Atomically dispersed active sites and a dynamic hydrogen‐shuttling mechanism enable barrier‐free deoxygenation and hydrogenation. Guided by molecular dynamics, design of experiments, and density functional theory, the alloy
