Nucleation‐Controlled Reconstruction of CuOx for Selective CO2 Electroreduction

Advanced Functional Materials, EarlyView.
The ratio of oxygen vacancies (Ov) and exposed Cu2O (111)/(200) of CuOx precatalyst is modulated by nucleation control of Cu(OH)2 precursor. Low Ov ratio and high ratio of Cu2O (111)/(200) in slow‐nucleated CuOx reconstructs to high‐coordinated oxide‐derived copper (OD‐Cu) during electrochemical CO2 reduction reaction (CO2RR) and exhibits enhanced ...

The lack of correlation between flat slabs and bathymetric impactors in South America [PDF]

, 2013
Flat slab subduction has been attributed to various causes including mantle wedge dynamics, overriding by the upper plate, age of the subducting plate, and subduction of anomalously thick oceanic crust. One often favored explanation for flat slabs is the

Interfacial and Crystallographic Regulation of Zinc Anode via Electric Double Layer Reconstruction for Highly Stable Zn Anode

Advanced Functional Materials, EarlyView.
Trace amounts of perfluoro‐1‐butanesulfonyl fluoride enables the regulation of the Zn/electrolyte interface by the generated zincophilic ─SO3H groups with long hydrophobic ─CF2 tails, which adsorb strongly onto the Zn surface, displace water molecules from the inner Helmholtz plane, and reconstruct the electrical double‐layer structure.

COMPARATIVE STUDY OF FLAT SLAB AND CONVENTIONAL SLAB USING ETABS

, 2022
In this thesis, the structural behavior of both flat slab and conventional slab in multi-storied building is to be compared. The rapid growth of the urban population and the consequent pressure on limited space has considerably influenced multi-storied building construction. . Two main groups according to the arrangement of slabs, beams or girders, and

Adaptive Hydrogels With Spatiotemporal Stiffening Using pH‐Modulating Enzymes

Advanced Functional Materials, EarlyView.
The chemomechanical coupling in an adaptive hydrogel is studied to further the development of adaptive hydrogels. This coupling is achieved by embedding a pH‐modulating enzyme in a pH‐responsive hydrogel. The enzymatic reaction can be triggered locally, which generates a pH‐decreasing wave throughout the system, increasing the crosslinking density and ...

Tailoring K+/Vacancy Disordered Layered Oxide via Charge Engineering for Stabilizing High‐Performance Potassium‐Ion Batteries

Advanced Functional Materials, EarlyView.
With a charge‐ion coupling engineering strategy, a K+/vacancy disordered K0.5Mn0.8Co0.1Ti0.1O2 material has been designed. The targeted transition metal doping disrupts charge ordering and inducing K+/vacancy disordering, thereby enabling rapid K+ diffusion through interconnected channels and a stable solid‐solution reaction mechanism.

Temperature‐Robust Interphase Enables Carboxylate‐Ester Electrolyte for Stabilizing High‐Voltage Sodium Batteries

Advanced Functional Materials, EarlyView.
A synergistic electrolyte engineering strategy of employing ethyl acetate (EA) with vinylene carbonate (VC) as multifunctional additives is initially pioneered, making various as‐prepared high‐voltage wide‐temperature sodium batteries work well via the formation of a gradient and temperature‐robust interphase.
