A novel rigid donor monomer, indacenodithieno[3,2-b]thiophene (IDTT), containing linear alkyl chains, is reported. Its copolymer with benzothiadiazole an excellent p-type semiconductor, affording a mobility of 6.6 cm2 V−1 s−1 in top-gated field-effect transistors pentafluorobenzenethiol-modified Au electrodes. Electrode treatment solution-deposited copper(I) thiocyanate (CuSCN) has beneficial hole-injection/electron-blocking effect, further enhancing the to 8.7 s−1. The demand for low-cost,...
Congestion in a Wireless Sensor Network (WSN) can cause missing packets, low energy efficiency, and long delay. Moreover, some applications, e.g. multimedia image, need to transmit large volumes of data concurrently from several sensors. These applications have different delay QoS requirements. problem is more urgent such applications. To address this challenge, we propose novel efficient congestion control scheme for sensor networks, called ECODA (Enhanced detection avoidance) which...
Highly sensitive detection of enhanced terahertz (THz) fingerprint absorption spectrum trace-amount tiny molecules is essential for biosensing. THz surface plasmon resonance (SPR) sensors based on Otto prism-coupled attenuated total reflection (OPC-ATR) configuration have been recognized as a promising technology in biomedical applications. However, THz-SPR the traditional OPC-ATR long associated with low sensitivity, poor tunability, refractive index resolution, large sample consumption,...

Balangia balangensis from Balang Formation eastern Ghuizhou Province, south‐west China. The complete protaspid to holaspid ontogeny incomplete meraspid ontogenies described. relative degree ontogenetic variation within lineage – is analysed indicates that may have...
Underlying the micromechanism of hydrate phase change is significant for marine natural gas resources exploitation; however, current nondestructive microtesting techniques still suffer from issues multiphase distinguish or continuous monitoring. Therefore, in this study, a direct real-time visualization method within 2.5D microchip was first proposed and applied research. Two different growth modes methane (CH4) methane-tetrahydrofuran (CH4-THF) after nucleation are found, their respective...
In this paper, we analyse the performance of a silicon nano-opto-electro-mechanical system (NOEMS) applied as an optical modulator, based on suspended slot waveguide driven by electrostatic forces. The analysis is carried out with help finite element (FEA) method involving influences from Casimir force, force and force. modulator are analysed aspects actuating modes, voltage, modulating frequency, effective index, phase change, energy consumption using FEA method. Simulation results show...
Abstract This work presents a distributed time‐slot assignment algorithm which adopts TDMA as Medium Access Control, specially suited to support applications with strict delay, jitter, and throughput requirements characterized by convergecast traffic pattern in sensor networks.

In path, sufficient resource reserved weighted fairness...
In this study, the authors present an alternative method for poor accuracy of piezoresistive meteorology pressure sensing in low‐temperature environment (down to −45°C) by incorporating external thermodynamic control. order use designed sensor such a environment, microelectromechanical systems (MEMS) chip itself has be kept at 50°C, which is most common used highest working temperature field. The heat compensation achieved pulse‐width modulation controlled heating resistor based on...
Based on Mason’s signal flow graph analysis, an analytical model of the optical mode localization based coupled ring resonators is established. The correctness theoretical proved by simulation. High sensitivity and common-mode rejection can be achieved evaluating modal power ratio from resonant peaks as sensing output. four-port structure, two output spectrum with (asymmetric splitting) symmetric splitting allows high-sensitivity dual-channel calibration to carried out simultaneously, which...
Mode localization is widely used in coupled micro-electro-mechanical system (MEMS) resonators for ultra-sensitive sensing. Here, the first time to best of our knowledge, we experimentally demonstrate phenomenon optical mode fiber-coupled ring resonators. For an system, resonant splitting happens when multiple are coupled. Localized external perturbation applied will cause uneven energy distributions split modes rings, this called localization. In paper, two fiber-ring The generated by...
