Self‐Healing Ionogel Dual‐Network Enables Synergistic Defect Passivation and Strain Relief for High‐Efficiency Robust Perovskite Photovoltaics

Advanced Science, EarlyView.
PSCs are afflicted by inherent defects and lattice strain that limit PCE and stability. A cross‐linked multifunctional ionogel [HA‐AA][EMIES] is developed to modulate crystallization, relieve residual strain, and passivate defects, extending carrier diffusion length to over 8 µm and delivering PCEs of 26.45% for rigid devices and 25.14% for flexible ...

Scanning Probe Microscopy: From Living Cells to the Subatomic Range

, 2010
In this chapter the reader will be introduced to scanning probe microscopy of samples varying by seven orders of magnitude in size (Fig. 13.1). The largest samples presented are living cells, measuring some hundreds of micrometers.

Multifunctional Ionic Liquid Enabling Cation Homogenization and Lead Chelation for Pure‐Iodide Wide‐Bandgap Perovskite Solar Cells

Advanced Science, EarlyView.
This work presents a multifunctional ionic liquid, [SO3H‐PMIm][OTf], that addresses A‐site cation inhomogeneity and lead toxicity in pure‐iodide wide‐bandgap perovskite solar cells. The additive enables homogeneous cation distribution, achieving 22.02% efficiency with 90% retention after 3000 h and reducing lead leakage by over 58%, thereby ...

Magnetic‐Field‐Tuned Spin‐Dependent D‐Band and Bifunctionality in L10‐FeCoPt for Enhanced Methanol Oxidation

Advanced Science, EarlyView.
The d‐band center and bifunctional mechanism jointly regulate the amounts of adsorbed OH* and CO*, thereby enhancing electrocatalytic performance, while the application of an external magnetic field further boosts this performance. ABSTRACT The spin‐dependent electronic structure of transition‐metal alloys plays a key role in tuning the magnetic‐field ...

Study of the tribocorrosion behaviors of albumin on a cobalt-based alloy using scanning Kelvin probe force microscopy and atomic force microscopy

Electrochemistry Communications, 2016
Abstract Once biomaterials are implanted in patients, the first reaction that occurs on the surface is the adsorption of biomolecules such as proteins, amino acids, etc. For load-bearing surfaces, some adsorbed proteins can be removed by relative motion (tribology) and some adsorbed proteins can be denatured due to tribochemical reactions.

Electron‐Rich Nickel Enabled by Charge Transfer in Multimetal Nanostructures for Efficient Ammonia‐to‐Hydrogen Conversion

Advanced Science, EarlyView.
A charge‐transfer‐engineered Ni catalyst derived from an atomically mixed layered precursor enables efficient ammonia‐to‐hydrogen conversion. Cr‐to‐Ni electron transfer creates electron‐rich Ni active sites that favor NH3 adsorption, modify the dehydrogenation energetics, and weaken N2 binding to facilitate product desorption. This electronically tuned
