TL;DR: In this article, for the first time in the field of piezoelectric materials, cement-based 0-3 PZT composites were fabricated by the normal mixing and spreading method.
Abstract: To meet the requirements of development for smart or intelligent structures in civil engineering, new functional materials that have good compatibility with civil engineering structural materials are needed. In this study, for the first time in the field of piezoelectric materials, cement-based 0-3 piezoelectric (PZT) composites were fabricated by the normal mixing and spreading method. The new materials have very good compatibility with portland cement concrete. The cement-based 0-3 piezoelectric composites were shown to have a slightly higher piezoelectric factor and electromechanical coefficient than those of 0-3 PZT/polymer composites with a similar content of PZT particles; thus, they are adequate for sensor application. There is potential for the application of cement-based 0-3 PZT composites in civil engineering because of their better piezoelectric properties and good compatibility with portland cement concrete.

TL;DR: In this article, the effect of different mixing approaches on the properties of ITZs in Recycled Aggregate Concrete (RAC) was investigated, and it was shown that two-stage mixing approach can improve the nanomechanical properties of the new ITZ by reducing the volume fraction of voids and Calcium Hydroxide (CH).

TL;DR: Screening chemokines that differentially induce chemotaxis of M1 and M2 macrophages and finding CCR7, the receptor for CCL19/CCL21, appeared to be an exception suggest that recruitment of M 1 and M1 macrophaging is fine tuned by different Chemokines with the involvement of specific signaling pathways.
Abstract: The homing of proinflammatory (M1) and the "alternatively activated" anti-inflammatory (M2) macrophages plays a different role in the process of inflammation. Chemokines are the major mediators of macrophage chemotaxis, but how they differentially regulate M1 and M2 macrophages remains largely unclear. In the present study, we attempted to screen chemokines that differentially induce chemotaxis of M1 and M2 macrophages and to explore the underlying mechanism. Among the 41 chemokines that specifically bind to 20 chemokine receptors, CCL19, CCL21, CCL24, CCL25, CXCL8, CXCL10, and XCL2 specifically induced M1 macrophage chemotaxis, whereas CCL7 induced chemotaxis of both M1 and M2 macrophages. Whereas the differential effects of these chemokines on M1/M2 macrophage chemotaxis could be attributable to the predominant expression of their cognate receptors on the macrophage subsets, CCR7, the receptor for CCL19/CCL21, appeared to be an exception. Immunoblot analysis indicated an equivalent level of CCR7 in the whole cell lysate of M1 and M2 macrophages, but CCL19 and CCL21 only induced M1 macrophage chemotaxis. Both immunoblot and confocal microscopy analyses demonstrated that CCR7 was predominantly expressed on the cell surface of M1 but in the cytosol of M2 macrophages before ligand stimulation. As a result, CCL19 or CCL21 induced activation of both MEK1-ERK1/2 and PI3K-AKT cascades in M1 but not in M2 macrophages. Intriguingly, CCL19/CCL21-mediated M1 macrophage chemotaxis was blocked by specific inhibition of PI3K rather than MEK1. Together, these findings suggest that recruitment of M1 and M2 macrophages is fine tuned by different chemokines with the involvement of specific signaling pathways.

TL;DR: In this paper, a new type of omnidirectional gaps is theoretically found in one-dimensional photonic crystals (1DPCs) composed of two kinds of single-negative (SNG) materials.
Abstract: A new type of omnidirectional gaps is theoretically found in one-dimensional photonic crystals (1DPCs) composed of two kinds of single-negative (SNG) (permittivity- or permeability-negative) materials. In contrast to the Bragg gaps, the properties (the central frequency and width of the gap) of such omnidirectional gaps are insensitive to the incident angles and the light polarizations, and are invariant upon the change of scale length. Such omnidirectional gaps result from the interaction of evanescent waves. When a defect layer is introduced, a defect mode appears inside the omnidirectional gap, and the spectral position of the defect mode is almost independent of incident angles and nearly invariant with the scaling.
