In?recent years, immunotherapies, such?as?those involving?chimeric?antigen?receptor?(CAR)?T?cells, have become increasingly promising approaches to?non-small-cell?lung?cancer?(NSCLC) treatment.?In?this study, we explored the antitumor potential?of?prostate stem cell?antigen?(PSCA)-redirected CAR?T?and mucin 1 (MUC1)-redirected CAR?T?cells?in?tumor models?of?NSCLC. First, we generated patient-derived xenograft (PDX) mouse models?of?human NSCLC that maintained the antigenic profiles?of?primary tumors. Next, we demonstrated the expression?of?PSCA?and?MUC1?in?NSCLC, followed by the generation and confirmation?of?the specificity and efficacy?of?PSCA-and?MUC1-targeting CAR?T?cells?against NSCLC cell lines?in?vitro. Finally, we demonstrated that?PSCA-targeting CAR?T?cellscould efficiently suppress NSCLC tumor growth?in?PDX mice and synergistically eliminate?PSCA(+)MUC1(+) tumors when combined with?MUC1-targeting CAR?Tcells. Taken together, our studies demonstrate that?PSCA?and?MUC1?are both promising CAR?T?cell?targets?in?NSCLC and that the combinatorial targeting?ofthese antigens could further enhance the antitumor efficacy?of?CAR?T?cells.

We used cesium stearate (CsSt) to modify the interface of the electron- extracting contact in inverted organic solar cells. Surface microstructure, optical properties, and electrical characterization as well as exciton generation rate and dissociation probability were investigated to understand the impact of CsSt on the interface contact. The results indicated that by incorporation of CsSt, the surface morphology and energy level as well as conductivity of a zinc oxide (ZnO) film were improved. On the basis of the above properties, highly efficient inverted organic solar cells have been demonstrated by using a ZnO nanoparticle film and CsSt stacked bilayer structure as the cathode interfacial layer. The insertion of a CsSt layer between the ZnO film and active layer improved the electron extraction efficiency, and a high power conversion efficiency (PCE) of 8.69% was achieved. The PCE was improved by 20% as compared to the reference device using a ZnO-only electron extraction layer.

In this study, (001) and (101)-orientated polycrystalline SnO films were respectively fabricated. The preferred orientation conversion was observed by modifying the stoichiometry of the SnO films. It was revealed that the O-rich and Sn-rich SnO films favor (001) and (101) grain orientations, respectively. Moreover, based on the Raman selection rule and our experimental results, the 110 cm 1 Raman peak is assigned to the low- frequency Eg mode of SnO. The Raman intensity ratio between the 110 cm 1 and 210 cm 1 peak of SnO increases with the relative texture coefficient of the (101) grain orientation but decreases with that of the (001) one, demonstrating that the Raman characteristic information could be used as fingerprint recognition to mutually predict the crystallographic texture of SnO films.

High-Performance Inverted Solar Cells Based on Blend Films of ZnO Naoparticles and TiO2 Nanorods as a Cathode Buffer Layer

We reported the favorable cathode buffer layer based on a blend of ZnO nanoparticles (NPs) and TiO2 nanorods (NRs) applied to inverted solar cells. In addition to the high optical transmittance, the resultant blend film gave a relatively dense film with lower roughness than that of the respective single-component film. This improved the interface contact between the buffer layer and photoactive layer and therefore reduced the contact resistance and leakage current. Moreover, the combination of NRs and NPs increased the efficiency of electron transport and collection by providing both a direct path for electron transport from TiO2 NRs and a large contact area between ZnO NPs and the active layer. Consequently, both the short-circuit current density (Jsc) and fill factor (FF) in the device were improved, leading to an improvement of the device performance. The best power conversion efficiency (PCE) based on the blend film as the buffer layer reached 8.82%, which was preferable to those of a single ZnO NP film (7.76%) and a TiO2 NR-based device (7.66%).

In this paper, Ga-doped ZnO (GZO) thin films are deposited on glass substrates by radio frequency magnetron sputtering for low loss plasmonic applications. The effects of Ga2O3 content in the target and substrate temperature on the electrical, structural and optical properties of GZO films are investigated. Film with the highest carrier concen- tration of 7.0 × 1020 cm? 3 was obtained at a Ga2O3 content of 5 wt% in the target under room temperature deposi- tion. With increasing deposition temperature, the lowest electrical resistivity of 3.8 × 10? 4 Ω cm was acquired at a deposition temperature of 200 °C. The values of plasmonic resonances wavelength could be changed from 1.35 to 2.39 μm by adjusting the carrier concentration. Material absorption losses in these GZO films are 10 times lower than that of conventional Ag films at telecommunication wavelengths. These results make GZO a promising low-loss plasmonic material operating at telecommunication wavelengths.

Heat accumulation is a severe problem for high-power light-emitting diodes (LEDs). Here, we introduce a thermostable and transparent lateral heat spreader as an additional heat-escaping channel of an LED chip to improve the thermal management of LED devices. The lateral heat spreader was prepared based on a silver nanowire (AgNW)/polyimide composite comprising a thin polyacrylate layer soldering a conductive AgNW network to confine the nanowires to the surface of a polyimide film and to obtain low contact resistance between the nanowires. The AgNW/polyimide composite film has a figure-of-merit sheet resistance of 7 ohm sq 1 with 76% transmittance at 550 nm. After heating at 200 C for 168 h, the sheet resistance increases to 16 ohm sq 1. The thermal conductivity and thermal diffusivity are 130.2 W m 1 K 1 and 60.5 mm2 s 1, respectively, which are comparable to those of a commercial copper foil. A demonstration shows the core temperature in a thermal diffusion apparatus can be lowered by 9 C. The experimental data combined with computational simulation indicate the Joule heating could be drawn away efficiently along the lateral heat spreader.

In this paper, flexible Ag electrodes with a hexagonal micromesh structure were fabricated on PET substrate using a photolithography technique. The effect of film thickness on optical and electrical properties of Ag electrodes was investigated systematically. Furthermore, these flexible transparent Ag mesh electrodes were firstly applied to a polymer dispersed liquid crystal (PDLC) device and its performance was evaluated. All of the Ag electrodes exhibited a high average transmittance of about 80.2–85.0% in the visible range (400–800 nm), and the minimum sheet resistance value reached 8.2 U sq 1. The prepared Ag mesh also showed an excellent performance of adhesion and bending, demonstrating its superior durability. The PDLC device based on Ag mesh electrodes showed comparable performance with that using ITO electrodes, indicating that the Ag mesh film can be a good substitution for ITO electrodes in PDLC devices and may find practical application in large area flexible devices.

In the preliminary design process of switched reluctance machine (SRM), adjusting the number of wingding turns or cross-sectional area of conductor to optimize windings design has dramatic effects on the performances like torque density, efficiency and thermal dissipation and so on. However, the difficulty exists on how to guarantee these performances while optimizing winding design. This paper proposes an analytical optimization design method based on an regulation model of ampere density and coil space factor, which can directly determine the optimal number of winding turns, the cross- sectional area of conductor, the ampere density and the coil space factor. And a MATLAB pre-design program has been developed to provide two design schemes respectively with and without the optimization model. The comparison analysis has been further carried out with finite element analysis (FEA). The simulation results verify that the performances can be highly improved with the proposed optimization model.
