A cytotoxicity test protocol for single-wall nanotubes (SWNTs), multi-wall (with diameters ranging from 10 to 20 nm, MWNT10), and fullerene (C60) was tested. Profound of SWNTs observed in alveolar macrophage (AM) after a 6-h exposure vitro. The increases by as high ∼35% when the dosage increased 11.30 μg/cm2. No significant toxicity C60 up dose 226.00 apparently follows sequence order on mass basis: > MWNT10 quartz C60. significantly impaired phagocytosis AM at low 0.38 μg/cm2, whereas...
We develop a novel strategy to more effectively and controllably process continuous enzymatic or homogeneous catalysis reactions based on nonaqueous Pickering emulsions. A key element of this is "bottom-up" construction macroscale flow reaction system through packing catalyst-containing micron-sized ionic liquid (IL) droplet in oil column reactor. Due the influx reactants into microreactors release products from microreactors, such can take place without limitations arising establishment...
Abstract Bio‐inspired machine visions have caused wide attentions due to the higher time/power efficiencies over conventional architectures. Although bio‐mimic photo‐sensors and neuromorphic computing been individually demonstrated, a complete monolithic vision system has rarely studied. Here, (NMVS) integrating front‐end retinomorphic sensors back‐end convolutional neural network (CNN) based on single ferroelectric‐semiconductor‐transistor (FST) device structure is reported. As...
In-sensor computing hardware based on emerging reconfigurable photosensors can effectively reduce redundant data and decrease power consumption, which greatly promote the evolution of machine vision. However, because complex device structures low integration abilities, common architectures mainly lie in two dimensions, resulting time area efficiencies. Here we propose a three-dimensional (3D) neuromorphic photosensor array for parallel in-sensor image processing. It is constructed vertical...
Abstract 2D‐layered materials and van der Waals heterostructures (vdWHs) have attracted intense interests in optoelectronic applications. However, the performance of photovoltaic effect based on vdWHs is still unsatisfactory, which subjected to many factors, including settled small built‐in potentials low light absorptions. Here, a pronounced reported MoTe 2 /(C 4 H 9 NH 3 ) (CH Pb I 10 /α‐In Se ferroelectric p–i–n vdWHs. An all‐dry transfer method held an inert environment utilized ensure...
Abstract In‐sensor computing can enhance the imaging system performance by putting part of computations into sensor. While substantial advancements have been made in latency, spectral range, and functionalities, strategy for in‐sensor light polarization has remained unexplored. Here, it is shown that ferroelectric‐reconfigurable polarization‐sensitive photodiodes (FPPDs) based on BiFeO 3 nanowire arrays perform information. This innovation leverages anisotropic photoresponse from 1D...
The fast development of artificial intelligence has called for high-efficiency neuromorphic computing hardware. While two-dimensional floating-gate memories show promise, their limited state numbers and stability hinder practical use. Here, we report gate-injection-mode as a candidate large-scale neural network accelerators. Through coplanar device structure design bi-pulse programming strategy, 8-bit states with intervals larger than three times the standard deviations over 10,000 s are...

Abstract Aluminum can enhance heat release of energetic composite in theory. However, the commonly used micron aluminum powder has several short comings like incomplete reaction and low rate. Meanwhile, outer oxide shell nano Al particle is thicker than micro Al, which leads to active content insufficient release. On basis previous research, reported fluoropolymers modified particles were compared suitable F2311was chosen. Sub-micron scale (median size around 200 nm) was regarded as optimum...
Porous nano‐aluminum@polymer microspheres with a narrow size range are fabricated to exploit the energy advantages of nano‐aluminum (nAl). Nitrocellulose (NC) and glycidyl azide polymer (GAP) act as functional binders adhere tightly surface nAl particles aggregate them into spheres. The formed holes on microsphere considered gas diffusion channels interior. Confined combustion results show that nAl@GAP generate highest peak pressure, maximum pressurization rate nAl@NC is comparatively higher...
Photodetectors based on low-dimensional materials usually suffer from serious optical power-dependent photoresponse and low reliability, particularly in the ultraviolet regime. The barrier photodetector is an effective reliable strategy where layer can block low-energy charge carriers while allowing for a flow of high-energy photocarriers. Here, vertical heterostructure photodetectors (VBHPs), consisting graphene bottom electrode, MoS2 light absorber, h-BN energy barrier, reliable, robust,...
