Record Energy Storage Performance Metrics in Ferroelectric Hafnia‐Based Films through Heterostructure Design

Advanced Functional Materials, EarlyView.
Dielectric capacitors typically struggle to achieve both high energy storage density and high efficiency at applied voltages below 10 V. Here, we address this challenge by introducing a novel hybrid fluorite/perovskite heterostructure design that combines ultra‐high recoverable energy storage density with efficient energy release (Uf ≈ 1016 J/cm3), at ...

High‐Throughput Exfoliation of Optoelectronic‐Grade MoS2 via Turbulent‐Flow Wet Jet Milling

Advanced Functional Materials, EarlyView.
A scalable wet jet milling exfoliation method is demonstrated for producing optoelectronic‐grade MoS2 nanosheets using environmentally friendly ethyl cellulose in ethanol dispersion media. Guided by fluid dynamics modeling, this approach is optimized to achieve record‐high exfoliation throughput and concentration.

Residual‐Lithium‐to‐LiF Conversion Enables a LiF–Fluorinated Carbon Interphase for Reconstruction‐Resistant Ni‐Rich Cathodes

Advanced Functional Materials, EarlyView.
A fluorine‐rich acrylate monomer (PFHEA) was solvent‐free applied to NCM90 and thermally decomposed under Ar to convert residual lithium into LiF and form a pre‐built LiF/fluorinated amorphous carbon (LiF/FC) interphase. The LiF/FC layer suppresses NiO rock‐salt reconstruction and microcrack propagation, lowers interfacial resistance, and improves Li ...

Electric field mill for the simultaneous measurement of electric field strength and ion current diensity

, 1995
In the last 20 years, the use of high voltage direct current (HVDC) power transmission has grown considerably. With the increase in the number of HVDC transmission lines and in the transmission voltages, concern has increased as to possible health effects. For research on these health effects to be carried out, it is necessary to measure the electrical

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

ON THE MILL TYPE ELECTRIC FIELD METER

ON THE MILL TYPE ELECTRIC FIELD METER
A mill type electric field meter with high time response has been constructed to measure the electric field change due to lightning discharge. Alternating voltage proportional to the field is produced by the mill consisted of sixty inductive electrodes and a rotary disc. The voltage is amplified and then fed into three recorders.
