The usage of wireless power transfer is not new nowadays particularly for the smartphone. Modern wireless power transfer technology already has a rich history of research and growth, as well as excellent marketing developments. One of the main goals of this study is to study and analyze the major challenges that affect the overall performance of the wireless charging system specifically improving further charging distance as compared to the current wireless mobile charger. By using the coil-size disparity method, the wireless charger is studied to operate over a longer distance. This work uses an impedance-based quality factor tuning technique to design the WPT system with coil size disparity. By varying the coupling coefficient and the inductor turn ratio, adjustments were made to the circuit to increase the transfer efficiency and to increase the distance of the device from the charging pad. The finding shows that the circuit could deliver a 3v dc voltage when the coupling coefficient is set to 0.1. © 2020 IEEE.

SENSORS AND ACTUATORS A-PHYSICAL 2021年 318卷 112523-112523页

In this paper, a new InGaZnO (IGZO) thin-film Uv Phototransistor (Photo-TFT) based on both dual material gate (DM) and plasmonic Ag nanoparticles (NPs) is proposed, in hope of combining the beauties of both aspects to achieve enhanced photogeneration/collection efficiency. An accurate drain-current model for the investigated device is developed, where a good agreement with the experimental data is achieved. The optical behavior of IGZO thin-film decorated with Ag NPs is analyzed using 3-D FDTD method. Interestingly, a strategic combination between the developed model and Particle Swarm Optimization (PSO) technique is conducted to find out the appropriate DM gate configuration and the best Ag NPs spatial arrangement offering the highest device Figure of Merits (FoMs). It is revealed that the optimized design showcases giant responsivity exceeding 10(3) A/W and superb detectivity of 6.8 x 10(14) Jones, which are far beyond conventional IGZO Photo-TFTs. These improvements are attributed to localized surface plasmon resonance effects (LSPR), leading to enhance the Uv-absorbance capability. Moreover, the optimized DM gate generates intense electric-field in the IGZO channel, allowing the efficient separation and transfer of photo-induced carriers. Therefore, promoting enhanced photogeneration/collection efficiency, this innovative strategy based on decorated Ag NPs combined with DM gate engineering provide a sound pathway for designing potential alternative IGZO Photo-TFT for the future optoelectronic technology.

Due to their efficient recognition and lysis of malignant cells, natural killer (NK) cells are considered as specialized immune cells that can be genetically modified to obtain capable effector cells for adoptive cellular treatment of cancer patients. However, biological and technical hurdles related to gene delivery into NK cells have dramatically restrained progress. Recent technological advancements, including improved cell expansion techniques, chimeric antigen receptors (CAR), CRISPR/Cas9 gene editing and enhanced viral transduction and electroporation, have endowed comprehensive generation and characterization of genetically modified NK cells. These promising developments assist scientists and physicians to design better applications of NK cells in clinical therapy. Notably, redirecting NK cells using CARs holds important promise for cancer immunotherapy. various preclinical and a limited number of clinical studies using CAR-NK cells show promising results: efficient elimination of target cells without side effects, such as cytokine release syndrome and neurotoxicity which are seen in CAR-T therapies. In this review, we focus on the details of CAR-NK technology, including the design of efficient and safe CAR constructs and associated NK cell engineering techniques: the vehicles to deliver the CAR-containing transgene, detection methods for CARs, as well as NK cell sources and NK cell expansion. We summarize the current CAR-NK cell literature and include valuable lessons learned from the CAR-T cell field. This review also provides an outlook on how these approaches may transform current clinical products and protocols for cancer treatment.

The development of electrochromic materials has opened the door to the development of numerous devices including smart windows, color displays, optical filters, wearable camouflages, among others. Although the current electrochromic devices do not consume energy while maintaining their colored or colorless states, their bistable operation requires external electrical energy to be consumed during switching. To reduce the energy consumption of an electrochromic device, an emerging Zn anode-based electrochromic device concept was recently introduced to partially retrieve the consumed electrical energy. In this Review, key technological developments and scientific challenges are presented for a broad range of Zn anode-based electrochromic device configurations with emphasis on the inherent distinctions between the Zn anode-based and conventional electrochromic devices. Specifically, a comprehensive comparison of the two classes of electrochromic devices in the high-performance device design is provided. For the electrochromic layer, the methods for obtaining high-quality electrochromic materials and thin films are reviewed. For the electrolytes, the effect of the dual ion system on the electrochromic performance is discussed. Also, some critical but unresolved issues in the device design and fabrication are discussed. The perspectives and outlook at the end of this Review provide recommendations to improve performance for future electrochromic studies.

Molecular engineering of the efficiency of new thieno[3,2-b]thiophene-based metal-free dyes owning different donor and π-linkers groups for use in the dye-sensitised solar cells: a quantum chemical study

引用

MOLECULAR PHYSICS 2021年第10期119卷 e1913250-e1913250页

In this work, the new metal-free organic donor-pi-acceptor (D-pi-A) D1-3L1-4 dyes formed from 2-cyanoacrylic as the electron acceptor (anchoring) group were investigated. Density functional theory (DFT) and time-dependent DFT (TD-DFT) were used to evaluate the electronic, structural, and optical properties of the organic dyes. The theoretical results show that the trend of the calculated HOMO-LUMO energy gap is in good agreement with the photophysical data. Key parameters of the sensitisers in the dye-sensitised solar cell devices associate with the short-circuit current density (J(sc)), electron injection driving force Delta G(inject), total reorganisation energy lambda(total) (lambda(h) and lambda(e)), light-harvesting efficiency (LHE), and open circuit potential (v-oc) were explored. The results show that increasing the length of pi-bridge has a significant effect on the electronic and optical properties of dyes. Further, donor moieties have a strong effect on the performance of dyes. Based on the obtained results, the D3L3 and D3L4 dyes could improve the light-harvesting efficiency, intramolecular charge transfer parameters, and electron injection efficiency. The results of this work can provide valuable insight into the design of DSSCs with high-efficiency.
