Although liquid crystal elastomers (LCEs) have demonstrated various applications in artificial muscles and soft robotics, their inherent flexibility orientation-dependent forces limit functions. For instance, LCEs can sustain a high actuation force when they contract but cannot elongate to drive loads with large displacements. In this study, it is that photocontrollable elongation strain be achieved polydomain by programming the crease structures well-defined order couple forces. Efficient...
To overcome the reversible nature of low-Reynolds-number flow, a variety biomimetic microrobotic propulsion schemes and devices capable rapid transport have been developed. However, these approaches typically optimized for specific function or environment do not flexibility that many real organisms exhibit to thrive in complex microenvironments. Here, inspired by adaptable microbes using combination experiment simulation, we demonstrate one-dimensional colloidal chains can fold into...
Microrobot swarms have seen increased interest in recent years due to their potentials for vivo delivery and imaging with cooperative propulsion modes enhanced signals. Yet most developed so far are limited dense particle aggregates, simpler than complicated three-dimensional assemblies of anisotropic particles. Here, we show via assembly path design that complex hollow tubular structures can be assembled from simple isotropic colloidal spheres those complicated, metastable, microtubes...
Microbot propulsion has seen increasing interest in recent years as artificial methods that overcome the well-established reversible and challenging nature of microscale fluid mechanics. While controlled movement is an important feature microbot action, many envisioned applications also involve cargo transport where microbots must be able to load unload contents on command while tolerating complex solution chemistry. Here we introduce a physical method uses flexible linked superparamagnetic...
Manipulation of micro/nano particles has been well studied and demonstrated by optical, electromagnetic, acoustic approaches, or their combinations. internal structure droplet/particle is rarely explored remains challenging due to its complicated nature. Here we the manipulation disk-in-sphere endoskeletal droplets using wave for first time. We developed a model investigate physical mechanisms behind this novel phenomenon. Theoretical analysis interactions indicated that these assembly...
Abstract Surface‐enhanced Raman scattering (SERS) is widely used in all kinds of detection due to its ultrahigh sensitivity and selectivity. Micromotors, when as SERS sensors, or the so‐called “hotspots on fly”, can combine both controlled mobility sensing capacity, are ideal for versatile situ detection. In this work, mobile sensors successfully fabricated by growing gold nanospikes onto magnetic microsphere surfaces. These micromotors act normal characterized trace thiram, a highly toxic...
Surface acoustic wave microfluidic technology has found great potential in biomaterials science thanks to its advantages micro/nano manipulation and characterization.
Anisotropic particles have been widely used to make micro/nanomotors that convert chemical, ultrasonic, electrical, or magnetic energy into mechanical energy. The moving directions of most colloidal motors are, however, difficult control. For example, asymmetric dimers with two lobes different sizes, ζ-potential, chemical composition shown rich propulsion behaviors under alternating current (AC) electric fields due unbalanced electrohydrodynamic flow. While they always propel in a direction...
W/Polydopamine (PDA) was prepared by adding W powder into the dopamine (DA) solution and adjusting pH value of solution. PDA contains several phenolic hydroxyl amino groups, which provide abundant active sites for complexation metal ions. Therefore, we W/Gd2O3 with core–shell structure self-assembly method homogeneous precipitation method, respectively. At same time, polyurethane (PU) coating fabrics Gd2O3 mixed were prepared, their X-ray protection performance tested. Results show that...
In order to elucidate the mechanism of CaO on pure oxygen combustion coke, non-isothermal TGA technique was use test coke blended samples varying C/Ca molar ratios (CMCa-2, CMCa-3, and CMCa-4). The characteristic temperatures at β were measured. representative CMCa-2 CMCa-4 tested by TG-MS determine effect combustion. Kinetics parameters for across various reaction phases determined using improved Coats-Redfern method. results showed that in atmosphere, temperature rise with increase β....

Abstract Magnetic microparticles (MPs) and nanoparticles (NPs) have long been used as ideal miniaturized delivery detection platforms. Their use micro‐ nanorobots (MNRs) is also emerging in the recent years with help of more dedicated external magnetic field manipulations. In this review, we summarize research progress on nanoparticle (MNP)‐based MNRs. First, fabrication from either template‐assisted NP doping methods or directly synthesized MPs summarized. The driving torque sources for...
The rigid electrode substrates of conventional photoelectrochemical (PEC) sensors have hindered their practical application in portable and wearable flexible sensors.

As CMOS scaling extends into 28nm technology, transistor behavior depends not only on its channel length and width, but also other layout geometric parameters the surrounding neighborhood. In this paper, a systematic study was conducted proximity effects (LPEs) of Poly/SiON logic transistors, which includes oxide diffusion (LOD) effect, dummy poly spacing (DPS) active area effect (ASE), well (WPE). We explored mechanisms behind these LPEs proposed physical models that can explain LPEs'...
