Abstract Lithium metal batteries specialize in energy density, while the immoderate dendrite growth and solid electrolyte interphase (SEI) proliferation have been impeding their practical application. The key is regulation of Li + diffusion/nucleation behaviors toward a dense deposition. Herein, 9 Al 4 /Li 3 N energized mixed ionic/electronic conductive (MIEC) interfaces are pre‐implanted both surface bulk lithium anode. Such MIEC activated from situ conversion nano‐alloying reactions...
In situ Ga-doped ZnO nanotips were grown on amorphous fused silica substrates using metalorganic chemical vapor deposition. Structural, optical, and electrical properties of as-grown are investigated. Despite the nature substrates, found to be single crystalline oriented along c-axis. Photoluminescence (PL) spectra dominated by near-band-edge emission with negligible deep-level emission. The increase in PL intensity from Ga doping has been attributed donor-related impurity Current–voltage...
Abstract As one of the most significant constituent parts wearable electronic systems, flexible pressure sensors can accommodate irregular surfaces and perform spatial mapping when subjected to external or strain stimuli. Herein, a sensor integrated with two interlocked micropillar arrays is demonstrated by facile cost‐effective metal‐assisted chemical etching (MaCE) method assistance polymer microspheres lithography technique.

Flexible and wearable sensors are now becoming the favorite of new information age for their great prospects, especially in human health monitoring, which mainly aimed at improving comprehensive sensing performance. However, equilibrium between sensitivity response time sensor has not been well balanced. Herein, a simple low‐cost strategy to fabricate flexible pressure based on thermoplastic polyurethane (TPU) substrate with unique surface stochastic morphology replicated from abrasive...
ABSTRACT Percolative dielectric composites of sulfonated poly(aryl ether ketone) (SPAEK) and acidified graphite nanosheets (AGSs) were fabricated by a solution method. The constant the as‐prepared composite with 4.01 vol % AGSs was found to be 330 at 1000 Hz; this significant increase compared that pure SPAEK. Through calculation, low percolation threshold AGS/SPAEK confirmed 3.18 (0.0318 volume fraction) AGSs; attributed large surface area high conductivity AGSs. Additionally, our...
The energy level alignment and conductivity of hole transport layers (HTLs) are critical to the performance perovskite solar cells (PSCs). Additive engineering is an effective approach, we introduced tri(4-trifluoromethylphenyl)phosphine (343FP) as additive into poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] (PTAA). Studies have shown that addition 343FP can lead improved charge properties in PTAA also enhance transport, leading device efficiency resulting cell. reduces highest occupied...
This new understanding and demonstration of features printed by proximity x-ray lithography allows a revolutionary extension simplification otherwise established processes for microfabrication. The ability to produce fine is controlled predominantly diffraction photoelectron blur. manifests itself as feature bias. In the classical approach bias minimized. Bias optimization in terms mask/wafer gap resist processing formation, on wafer, smaller than those mask: thus producing local...
