Two-dimensional layered perovskite ferroelectric with giant piezoelectric voltage coefficient.

Piezoelectric sensors that can work in various conditions with superior performance are highly desirable with the arrival of the Internet of Things. For practical applications, large piezoelectric voltage coefficient g and high Curie temperature Tc are critical to the performance of piezoelectric sensors. Here, we report a two-dimensional perovskite ferroelectric (4-aminotetrahydropyran)2PbBr4 [(ATHP)2PbBr4] with a saturated polarization of 5.6 μC cm-2, high Tc of 503 K [above that of BaTiO3 (BTO, 393 K)],...


Piezoelectric Energy Harvesting from Two-dimensional Boron Nitride Nanoflakes.

Two-dimensional piezoelectric hexagonal boron nitride nanoflakes (-BN NFs) were synthesized by a chemical exfoliation process and transferred onto an electrode line-patterned plastic substrate to characterize the energy harvesting ability of individual NF by external stress. A BN single NF produced the alternate piezoelectric output source of ~50 mV and ~30 pA when deformed by mechanical bendings. The piezoelectric voltage coefficient (g) of a BN single NF was experimentally determined to be 2.35 × 10 V·m...

Piezoelectricity in Multilayer Black Phosphorus for Piezotronics and Nanogenerators.

Recently, piezoelectric characteristics have been a research focus for 2D materials because of their broad potential applications. Black phosphorus (BP) is a monoelemental 2D material predicted to be piezoelectric because of its highly directional properties and non-centrosymmetric lattice structure. However, piezoelectricity is hardly reported in monoelemental materials owing to their lack of ionic polarization, but piezoelectric generation is consistent with the non-centrosymmetric structure of BP. Theore...


Utilization of a magnetic field-driven microscopic motion for piezoelectric energy harvesting.

In spite of the recent advances in the development of high performing piezoelectric materials, their applications are typically limited to the direct conversion of mechanical impact energy to electrical energy, potentially risking mechanical failures. In this study, we developed piezoelectric poly(vinylidenefluoride-trifluoroethylene) (P(VDF-TrFE)) nanofibers integrated with SiO2-shelled Fe3O4 magnetic nanoparticles, to utilize magnetic energy to reliably drive the piezoelectric effect. Specifically, we sho...

Vitrimer-Cellulose Paper Composites: A New Class of Strong, Smart, Green and Sustainable Materials.

Vitrimer, the third category of polymer materials, combines the properties of traditional thermosets and thermoplastics and have gained much interest from industry since the first report in 2011. Currently, many researchers focus on the exploration of new chemistry for novel vitrimer synthesis, but pay less attention to fabrication of vitrimer composites based on known vitrimer systems. The latter can not only largely decrease the cost of vitrimers but also pro-vide a facile way to increase the variety of v...

The monolithic integration of sub-micron quartz structures on silicon substrates is a key issue for the future development of piezoelectric devices as prospective sensors with applications based on the operation in the high frequency range. However, to date it has not been possible to make existing quartz manufacturing methods compatible with integration on silicon and structuration by top down lithographic techniques. Here we report unprecedented large-scale fabrication of ordered arrays of piezoelectric e...

Significance of electrostatic interactions due to surface potential in piezoresponse force microscopy.

Piezoresponse force microscopy (PFM) has gradually becomes indispensable tool to investigate local piezoelectric and ferroelectric properties in diverse material systems. However, numerous reports have shown that the PFM signal can originate from several non-piezoelectric origins. Among them, because the electrostatic interaction between the AFM tip/cantilever and sample surface can be readily involved, it can be the most important factor during PFM measurement. In particular, in materials with relatively l...

Biocompatibility of (Ba,Ca)(Zr,Ti)O piezoelectric ceramics for bone replacement materials.

Total joint replacement implants are generally designed to physically mimic the biological environment to ensure compatibility with the host tissue. However, implant instability exposes patients to long recovery periods, high risk for revision surgeries, and high expenses. Introducing electrical stimulation to the implant site to accelerate healing is promising, but the cumbersome nature of wired devices is detrimental to the implant design. We propose a novel strategy to stimulate cells at the implant site...

Probing Effective Out-of-Plane Piezoelectricity in van der Waals Layered Materials Induced by Flexoelectricity.

Many van der Waals layered 2D materials, such as h-BN, transition metal dichalcogenides (TMDs), and group-III monochalcogenides, have been predicted to possess piezoelectric and mechanically flexible natures, which greatly motivates potential applications in piezotronic devices and nanogenerators. However, only intrinsic in-plane piezoelectricity exists in these 2D materials and the piezoelectric effect is confined in odd-layers of TMDs. The present work is intent on combining the free-standing design and p...

Correction to "Flexible and Robust Piezoelectric Polymer Nanocomposites Based Energy Harvesters".

Intracellular pH-propelled assembly of smart carbon nanodots and selective photothermal therapy for cancer cells.

A kind of smart carbon nanodots (CNDs) with the pH response feature was prepared by the one-pot hydrothermal treatment of citric acid and dicyandiamide, which was used for the differentiation of cancer/normal cells and the selective photothermal therapy (PTT) of cancer cells. When the smart CNDs were cultured with cells, they were highly internalized in the lysosomes of cells. Since the small-sized CNDs (about 5 nm) tends to form aggregation (as large as about 20 nm or even larger) under an acid conditi...

Adaptation and Evolution of Biological Materials.

Research into biological materials often centers on the impressive material properties produced in Nature. In the process, however, this research often neglects the ecologies of the materials, the organismal contexts relating to how a biological material is actually used. In biology, materials are vital to organismal interactions with their environment and their physiology, and also provide records of their phylogenetic relationships and the selective pressures that drive biological novelties. With the pape...
