“…The coating damages could be repaired by the release of core. As described in literature, 10,11 nano sizes microcapsules were the preferred choice for short term corrosion protection compared to long term. Therefore, a common problem in these systems is the inability to completely reinstall the large defects.…”

“…Since pioneering works by Schuhmann et al [ 31 ], the redox competition mode (RC mode) has been extensively used to investigate biological processes. In this mode, the tip and substrate are polarized at a certain potential to compete for the same analyte in a relatively narrow gap, as shown in Figure 2 g [ 32 , 33 ]. When scanning at a constant height in the vicinity of the substrate, the reductive current collected at the tip mostly remains constant above the inactive area.…”

Scanning electrochemical microscopy (SECM) is a chemical microscopy technique with high spatial resolution for imaging sample topography and mapping specific chemical species in liquid environments. With the development of smaller, more sensitive ultramicroelectrodes (UMEs) and more precise computer-controlled measurements, SECM has been widely used to study biological systems over the past three decades. Recent methodological breakthroughs have popularized SECM as a tool for investigating molecular-level chemical reactions. The most common applications include monitoring and analyzing the biological processes associated with enzymatic activity and DNA, and the physiological activity of living cells and other microorganisms. The present article first introduces the basic principles of SECM, followed by an updated review of the applications of SECM in biological studies on enzymes, DNA, proteins, and living cells. Particularly, the potential of SECM for investigating bacterial and biofilm activities is discussed.

“…With the merits of being lightweight, structurally versatile and having large recovery ability [11], SMPs exhibit tremendous advantages over shape memory alloys (SMAs) and shape memory ceramics (SMCs) [12,13]. These advantages provide SMPs with potential applications in aerospace [14], self-healing materials [15,16,17,18], intelligent textiles [19,20] and biomedical devices [21,22,23].…”

A series of shape memory blends of natural Eucommia ulmoides gum (EUG) and low-density polyethylene (LDPE) with a bicontinuous cross-linked structure were prepared by a physical blending method, which could be used in the field of thermal response with two different temperatures. We report the shape memory properties of these blended materials with two response temperatures for the first time. The mechanical, curing, thermal and shape memory properties of the blends were studied in this manuscript. Schematic diagrams are proposed to illustrate the dual shape memory behaviors of the EUG/LDPE blends. Our study focused on observing the relationship between the shape memory behavior and the microscopic crystalline phase states in the blends. In the blends, both the cross-linked network and the LDPE crystalline regions could act as fixed domains, while the crystalline regions of LDPE or EUG could act as the reversible domain. The shape memory properties were mainly determined by the components of the fixed and reversible domains. We focused on the shape memory behavior of blends at 60 °C and 130 °C in this manuscript. The results showed that when the peroxide dicumyl peroxide (DCP) dosage was 1.0 phr, the blends exhibited acceptable shape behavior at 60 °C (R1f = 74.8%, R1r = 63.3%). At the same time, when DCP dosage was 0.4 phr, the shape memory behavior of the blends at 130 °C was good and much better than that at 60 °C (R2f = 91.1%, R2r = 89.4%).
