While previously shown for microfluidics, OSTE+ has not yet been embedded with functional (e.g., magnetic) particles. We demonstrate that a magnetic OSTE+ using a matrix polymer of OSTEMER 324 Flex embedded with 25% by weight rare earth ((Nd0.7 Ce0.3)10.5Fe83.9B5.6) magnetic powder remains flexible after photopatterning, can be permanently magnetized, and retains a permanent magnetic field for at least 15 months. We develop a fabrication flow for this new material, as well as determine its ultraviolet (UV) curing times. Further development of magnetic OSTE+ could advance the integration of flexible M-CP microactuators into mass-manufacture, as OSTE+ integrates well with diverse substrates and can be tailored to have different ranges of Young's modulus, allowing for flexible actuators to be built into an otherwise rigid device.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"78 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83940580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Consequently, green and eco-friendly graphene inks are proposed that are free of VOCs and harmful organic compounds. Three graphene inks indicated as GGe, GTr, and GTw were prepared with corresponding optimized biopolymer concentrations of 0.1 mg.mL−1 of gelatin, 1 mg.mL−1 triton X-100, and 1.5 mg.mL−1 tween-20. The flake diameter distribution for the graphene inks ranged from 100 nm to 800 nm as measured by dynamic light scattering (DLS). GTr is made of smaller flake diameters followed by GTw and GGe has the largest flakes. Graphene films were printed using aerosol jet technique with a 500 nm thickness and their sheet resistance (sR) was of $2.6 mathrm{k}Omega/square$ for GTr, $5 mathrm{k}Omega/square$ for GTw, and $14 mathrm{k}Omega/square$ for GGe. The low sheet resistance for GTr was assigned to better ink wettability and adhesion on top PET substrates. These electrical resistances are suitable for the fabrication of green chemiresistive flexible sensors.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"27 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78350545","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding of mechanisms in the discharge and plasma-electrode interactions are needed to improve the efficiency of nanoparticles synthesis. In this study, we used a homemade pulsed power supply to produce spark discharges in deionized water with different electrodes, namely Cu, Al, and Steel. Voltage and current waveforms are acquired for discharges with various inter-electrode distances and applied voltages. The data is processed to report some characteristics of the discharges, such as breakdown voltage, discharge delay, injected charge, and energy. Also, we used a fast camera to visualize the dynamics of the post-discharge cavitation bubble. A relationship has been established between the discharge characteristics and the bubble dynamics; we found that higher is the injected energy larger is the bubble radius.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"135 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79563833","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The measured R and T characteristics of NCs were compared with the numerical FDTD models. Two approaches were used: (1) Individual Mo nanoparticles with proper size and distribution (bcc lattice) were modelled. (2) NCs layers were modelled as homogeneous thin films with optical constants (real and imaginary parts of the complex index of refraction) obtained through Maxwell Garnett effective medium approximation. In both cases, optical constants of pure bulk Mo and sputtered Mo were used, and the results were compared.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"9 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83844691","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The CSRRs incorporated inside the patch (A1) give a major contribution to the performance of the antenna. The simulation results show an improvement of the reflection coefficient $vertmathrm{S}_{11}vert$ from −20 dB to −38 dB for A2, and of the directivity from 4.68 dBi to 5.68 dBi when considering A1. The paper also proposes the fabrication of a metasurface-based patch antenna loaded with a carbon nanotube (CNT) thin layer for detection of deoxyribonucleic acid (DNA). The measured results demonstrate a frequency shift of about 69 MHz and a phase shift of about 28° for Al loaded with both CNTs and DNA in comparison with the same antenna loaded just with CNTs. In the case of A2, the frequency shift and the phase shift of the antenna loaded with CNTs and DNA become equal to 704 MHz and 121°, respectively.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"58 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86903075","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A straightforward method for printing a dense and thin gate oxide with a leakage current of less than 38 nA/cm2 at 1 MV/cm, a breakdown voltage greater than 4.5 MV/cm, and a relative permittivity of approximately 10 is described in this paper. We printed these TFTs on finely polished high purity aluminum sheets. After preparing the Al substrate with controlled oxidation to create the gate dielectric, we prepared a fresh solution of NH4OH:H2O2:H2O and immediately inkjet printed it on the substrate. Hereby the gate oxide is formed after 10 min without any additional annealing process. We rinsed the devices in ultrapure water and blow-dried them with nitrogen for 10 minutes after printing. Afterward, we printed and annealed indium gallium zinc oxide (IGZO) as a semiconductor. Finally, we printed the sources/drains and contacts with silver ink.","PeriodicalId":6742,"journal":{"name":"2021 IEEE 16th Nanotechnology Materials and Devices Conference (NMDC)","volume":"3 1","pages":"1-4"},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81844784","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
