Mechanically Robust and Ion‐Conductive Polyampholyte Elastomers via Dimeric Ionic Bonding
Advanced Materials, EarlyView.This study introduces a new class of polyampholyte ionic elastomers balancing both high mechanical strength and ionic conductivity by utilizing a novel precipitation method to create ionic dimers. The resulting elastomers exhibited strong mechanical performance and excellent ion mobility, making them ideal for applications in flexible electronics ...

Photocatalytic Aqueous Reforming of Methyl Formate
Advanced Materials, EarlyView.A 3d‐metal Cu‐based atomically dispersed photocatalyst, supported on modified g‐C₃N₄, facilitates the photocatalytic selective hydrogen (7.5 mmol gcat−1 of hydrogen; nothing else than H2 and CO2) generation from methyl formate. This diverse system functions under mild conditions, providing high hydrogen yield, selectivity, and enduring stability ...

Einstein's gravitation is Einstein-Grossmann's equations [PDF]
JOURNAL OF ADVANCES IN PHYSICS, 2015 While the philosophers of science discuss the General Relativity, the mathematical physicists do not question it. Therefore, there is a conflict. From the theoretical point view “the question of precisely what Einstein discovered remains unanswered, for we have no consensus over the exact nature of the theory's foundations.

Advanced Materials Interfaces, EarlyView.The molecular level understanding of proteins at oil‐water interfaces is deepened. Cruciferin assumes trimeric conformations at the interface, as in solution. Interfacial mobility is only marginally lower than in solution, indicating the chemical structure preserves a network.

Physics in Perspective, 2019 Einstein’s life-long effort to develop a theory that unifies gravitation and electromagnetism was not a purely theoretical enterprise. The technical environment of a gyrocompass factory triggered his search for a novel connection between the rotation of an electrically uncharged body and its magnetic field. The dimensional equality of the electric unit
