Summary: The increasing resistance of bacteria to antibiotics is a major global public health threat. Current antibiotic treatments are hindered by poor delivery to the infection site, leading to off-target effects and drug resistance. This study presents micro- and nanomotors that autonomously deliver antibiotics to specific areas, showing effective bactericidal activity against Gram-positive and Gram-negative bacteria in vitro by rapidly depolarizing their membrane. This technology provides a much-needed tool to direct therapeutics to infection sites and combat drug-resistant infections.

Summary: Scientists have designed synthetic molecular motors inspired by nanomotors in nature to drive the motion of microscale objects through cooperative reorganization. In this study, topological vortices are imprinted in monolayers of azobenzene molecules, which induce the collective motion of liquid crystal molecules and the spatiotemporal evolutions of nematic disclination networks. The collective transport and reconfiguration of colloidal assemblies can be controlled by manipulating the irradiated polarization, opening opportunities for programmable colloidal machines and smart composite materials.

Summary: In this study, we report the remarkable directional movement of cadmium chloride tetrahydrate (CdCl24H(2)O) nanomotors under electron beam irradiation. The nanomotors exhibit asymmetric surface facets, with the flat end moving in the direction of motion. The speed of movement is affected by changes in the nanomotor morphology. Finite element simulation reveals that ionic self-diffusiophoresis plays a key role in driving the nanomotor movement, as the nanomotor generates its own local ion concentration gradient due to different chemical reactivities on different facets.

Summary: Thermal behavior and phase ratios optimization of Sn/Cu composite solders were studied. The results showed that increased solid-liquid contact area promoted the formation of IMC, resulting in decreased melting endothermic peak temperature of Sn and its enthalpy change. The in situ temperature rose with higher solid-liquid contact area during ultrasonic-assisted transient liquid phase. The phase ratio of residual Cu and Cu3Sn increased with decreasing solid-liquid contact area after U-TLP, while it increased with more initial Cu content.

Summary: A fiber curvature and angle sensor based on LP21 mode reflected by a fiber Bragg grating (FBG) inscribed in a four modes fiber (FMF) is developed. LP21-LP01 coupling is revealed to be more sensitive to fiber bending compared with LP11-LP01 and LP02-LP01 coupling. The sensor has potential application prospects in curvature and angle detection fields due to its simple structure, ease of fabrication, and reliable response performance.

Summary: This paper presents a complex combining method for designing wideband Outphasing power amplifiers (OPAs). The method uses complex combining impedance to compensate for the frequency dispersion of the active load modulation in the OPA, extending its bandwidth. It is illustrated for the first time that the load modulation trajectories of the OPA can be corrected over a wide bandwidth by designing the complex combining impedance.

Summary: In this paper, a robust constrained filtering algorithm called recursive constrained least arctangent (RCLA) adaptive algorithm is proposed. By introducing a novel cost function framework, the proposed RCLA algorithm shows superior convergence performance and better steady-state behavior against impulsive noises compared to other existing recursive methods. The mean square convergence analysis and theoretical transient mean square deviation (MSD) are derived in detail. Computer simulations are conducted to validate the theoretical analysis and verify the superior behavior of the proposed RCLA algorithm compared to known algorithms under non-Gaussian environments.

Summary: This study demonstrates the noncontact immobilization of Ti3C2Tx MXene on a planar microwave resonator sensor using a polyimide film, leading to improved gas detection sensitivity for detecting acetone gas at the part per million -level. The sandwiching of a polyimide (PI) film between the resonator's interdigital capacitor structure and the MXene layer creates a strong electromagnetic field, allowing for significant interaction between acetone gas molecules and the resonator's EM field via the MXene layer. Compared to direct deposition of MXene on the resonator surface, the contactless immobilization of the MXene layer enhances acetone gas detection sensitivity by 110%. Two sensor prototypes were implemented, one with layers of PI film and MXene and the other with MXene only, and both exhibited linear correlation between resonant frequency and acetone gas concentration, high sensitivity (17.85 kHz/ppm), fast response time (60 s), and recovery time (85 s).

Summary: A low-complexity Digital PreDistortion (DPD) method based on Improved Sparse Least Squares Twin Support Vector Regression (ISLSTSVR) modeling theory is proposed in this paper to tackle the resource consumption issue caused by the nonlinearity of the power amplifier in the RF front-end of high-capacity satellite communication. Experimental results show that this method can significantly reduce the coefficients and computational complexity of the DPD model while maintaining its accuracy, providing an effective idea and method for coefficient dimension reduction in the predistortion technology of spaceborne RF front-ends.

Summary: In traditional Digital PreDistortion (DPD) models, the same set of polynomial models and memory model are used to linearize the Power Amplifier (PA) at all input signal powers. However, different power levels exhibit different nonlinear characteristics and memory effects in PAs. To solve this problem, a DPD model based on the blind K-Nearest Neighbor (KNN) algorithm with dimension weighting is proposed. The proposed method is experimentally verified using a Doherty PA and a three carrier Long Term Evolution (LTE) signal.
