“…The Co 3 O 4 /CNNS-1100 composite coupled with PMS was highly effective for TC remove within pH ≈2.0-10.0, wherein ≈99% TC was removed within 60 min reaction, which confirmed that the solution pH has minor effect on TC degradation. A mixture of anions such as Cl − , NO 3 − , HCO 3 − , and PO 4 3− might impact the pollutants removal ( Figure 6F). The listed anions exhibited the inhibition effect for TC degradation, while ≈95.7% TC still could be degraded by Co 3 O 4 /CNNS-1100 composite within 60 min.…”

The development of effective approaches for the preparation of 0D quantum dots (QDs)/2D nanosheets (NSs) heterostructures, which have been proven to be favorable for heterogeneous catalysis, is highly desirable but remains a great challenge. Herein, 0D metal oxide nanocrystals-2D ultrathin g-C N nanosheets (Co O /CNNS) heterostructures are synthesized via a facile chemical reaction, followed by annealing in air. Ultrafine Co O QDs (≈2.2-3.2 nm) are uniformly and tightly attached on the surface of g-C N nanosheets. Detailed characterization reveals that the specially designed unique 0D/2D structure is critical to the high photocatalytic performance for the degradation of tetracycline (TC) via peroxymonosulfate (PMS) activation. The optimal catalyst, namely, Co O /CNNS-1100, exhibits excellent performance and ≈98.7% TC can be degraded under visible light irradiation. Moreover, TC degradation is almost completely insusceptible to several real water samples. Meanwhile, other dye pollutants can also be efficiently degraded by the Co O /CNNS-1100/PMS/vis system. The quenching tests display that that the h , ∙OH, O , and SO are responsible for TC removal. The improved photocatalytic performance can be attributed to the synergistic effect of the photocatalytic- and chemical-processes in the PMS activation. This work gives an insight into the development of multifunctional 0D/2D nanocomposites for further potential applications which are not limited to environmental purification.

The development of stable Janus architectures suitable for biphasic applications holds significant importance. A novel approach is introduced for interfacial supramolecular self‐assembly, resulting in 2D Janus nanosheets (OA‐TA/Fe) exhibiting an amphiphilic nature. These nanosheets consist of hydrophilic coordination complexes of ferric ions (Fe3+) and tannic acid (TA) on one side of both surfaces and hydrophobic alkyl chains on the other side of both surfaces. The synthesis of these 2D Janus nanosheets involves a simple, ultrafast, and environmentally benign process, eliminating the need for time‐consuming multistep procedures and harsh synthetic conditions typically associated with Janus architecture formation. By exploiting the inherent singular anisotropic wettability inherent in OA‐TA/Fe‐2, the efficacy of these innovative Janus nanosheets in the efficient separation of various organic liquid‐in‐water and water‐in‐organic liquid emulsions is elucidated. Subsequent post‐modification of OA‐TA/Fe has facilitated the highly efficient remediation of contaminated oily wastewater, serving as a model biphasic catalysis reaction, wherein the Janus nanosheets function simultaneously as emulsifiers and catalysts within biphasic mixtures. The methodology establishes a rapid self‐assembly approach for the creation of amphiphilic free‐standing Janus nanosheets, offering compelling prospects for their application in diverse fields, as exemplified by, but not limited to, the case studies presented herein.

Highly Oriented Electrospun P(VDF‐TrFE) Fibers via Mechanical Stretching for Wearable Motion Sensing

materials, piezoelectric materials, which can convert mechanical shape changes into electric outputs, are particularly favorable to fabricate wearable devices for mechanicalrelated sensing and power generation. [15][16][17] According to material molecular compositions, piezoelectric materials are generally divided into ceramics and polymers. Indeed, even though inorganic piezoelectric materials offer high piezoelectric property, they are mechanically hard and brittle, which have difficulties to be directly applied to wearable devices. Besides, many piezoelectric ceramics contain heavy metal elements such as lead, that are harmful to human and environment. [18][19][20] On the other hand, piezoelectric polymers, represented by polyvinylidene fluoride (PVDF) and its copolymer poly[(vinylidenefluoride-cotrifluoroethylene] (P(VDF-TrFE)), are more preferable for wearable devices as they are lightweight, stretchable, environmentfriendly and chemically stable. [21,22] To construct piezoelectric polymer fibers, electrospinning, as a representative template-free method, [23,24] is a versatile technique to produce extended length of fiber-shaped structures with a number of advantages such as large surface area, tunable surface morphologies, and enhanced mechanical performance. [25][26][27][28] With electrospinning, when the droplet of polymer solution is charged by high applied voltage, the liquid droplet is pulled into a thin fiber and then collected by the grounded electrode. However, this liquid-to-solid transferring process normally results in randomly distributed fibers with poor electrical properties and limited response to mechanical stimuli. Therefore, to improve the performance of electrospun fibers, several methods have been demonstrated to obtain aligned electrospun fibers. [29][30][31][32][33] Two most frequently adopted methods are: 1) using a high-speed rotating collector with a very sharp edge, [34][35][36] and 2) using two separated parallel electrodes. [37,38] A very high rotating speed (>3000 rpm) is necessary for the rotating collector method, which brings high requirements to the fabrication facilities and increases electricity consumption. Also, the necessary role of sharp edge further restricts the amount of highly aligned electrospun fibers that can be collected. The parallel electrode method, on the other hand, can only fabricate aligned electrospun fibers in a very limited length, typically on millimeter scale.Advances in functional fabrics enable the realization of wearable devices in the form factor of fibers that can be seamlessly adapted in our daily lives. For mechanical-related sensing and power generation, piezoelectric materials are particularly favorable because they can convert mechanical shape changes into electric outputs. Electrospinning is a widely applied technique to produce extended length of fiber-shaped piezoelectric devices. However, this versatile process normally results in randomly distributed fibers with poor electrical properties and limited response to mechanical stimuli. H...
