Gapless Superconductivity From Extremely Dilute Magnetic Disorder in 2H‐NbSe2‐xSx

open access: yesAdvanced Materials, EarlyView.
We demonstrate that 2H‐NbSe2‐xSx hosts gapless superconductivity at unexpectedly low magnetic impurity concentrations. Combining STM, Bogoliubovde Gennes simulations, DFT, and quasiparticle interference, we comprehensively study the development of gapless behavior and show that SeS substitution reshapes the band structure, enhances nesting, and drives ...

Breaking the 2‐nm Barrier in Hard Disk Drives Using Monolayer Amorphous Carbon Overcoats

open access: yesAdvanced Materials, EarlyView.
The rapid growth of AI has increased demand for large‐scale data storage, making HDDs indispensable in data centers. Increasing areal storage density is crucial, but limited by the traditional carbon overcoats (COC). Monolayer amorphous carbon (MAC) offers a superior alternative.

Universal Fluorine‐Free Proton Exchange Polymers for High‐Performance and Durable Fuel Cells Operable Under Severe Conditions

open access: yesAdvanced Materials, EarlyView.
Due to excellent physical and chemical stability, the novel designed fluorine‐free polymers with aliphatic‐chain backbones (SP‐PAC12‐QP) are regarded as promising and universal alternatives to perfluorosulfonic acid membranes. Their performances are further improved by physical reinforcement, where the fuel cell performance under high temperature and ...

Emergent Freestanding Complex Oxide Membranes for Multifunctional Applications

open access: yesAdvanced Materials, EarlyView.
This review surveys freestanding oxide membranes and covers fabrication and three pathways for studies and devices: strain‐free and strained membranes, and van der Waals‐integrated heterostructures. We show how coupled oxide responses map onto these routes and cross‐couple to expand behaviors.

Evaluation of push-out bond strength of surface treatments of two esthetic posts

open access: yesIndian Journal of Dental Research, 2012
To evaluate the push-out bond strength of two surface treatments of a glass fiber and zirconia ceramic post.Sixty samples were fabricated and divided into two main groups according to the type of esthetic post indicated for maxillary central incisor: glass fiber post and zirconia ceramic post. Each group was subdivided to two subgroups according to the

Chemomechanical Origin of Morphological Disparity in Lithium Metal Electrodeposition

open access: yesAdvanced Materials, EarlyView.
Selective dissociation of either solvent or salt on copper current collector induced different solid electrolyte interphase (SEI) layers. The solvent derived organic SEI favors formation of Li whisker, while salt derived SEI favors formation of Li particle, revealing the root cause of Li morphology disparity within the same cell.
