Compact Plasma Ionization for Ion Mobility Spectrometry Using a 4.3 MHz Miniature Tesla Coil.

In this study, a low-cost 4.3 MHz plasma ionization source for ion mobility spectrometry (IMS), utilizing a miniaturized Tesla coil, is presented. This compact design, combined with a 3D printed cyclic olefin copolymer (COC) housing, delivers a stable and directed plasma suitable for ionization in IMS applications. The 3D printed housing ensures chemical resistance and low off-gassing, which are crucial for maintaining sample integrity. The Tesla coil produces a consistent sine wave at 4.3 MHz, and when connected to stainless steel screw electrodes it generates a stable plasma capable of ionizing analytes such as limonene, MTBE, nicotine, 2-octanone, and propofol. Measurements were conducted in both positive and negative ion modes. The results demonstrate the Tesla coil's effectiveness as a low-cost and reliable ionization source for IMS, offering comparable performance to traditional Ni63 β-emitters. This advancement in plasma ionization technology could facilitate more accessible and flexible IMS systems for diverse analytical applications. The integration of 3D printing in the development of this ionization source underscores the potential for customized, low-cost analytical instrumentation, promoting innovation in laboratory environments and commercial applications.

Enhancing silicon spectral emission in LIBS using Tesla coil discharge

Laser-induced breakdown spectroscopy (LIBS) is a powerful technique for elemental analysis, offering rapid analysis, minimal sample preparation, wide elemental coverage, and portability. To enhance the detection sensitivity of LIBS, increasing the spectral emission intensity is crucial. This paper explores the use of Tesla coil (TC) discharge as an alternative to spark discharge in silicon LIBS. The study examines the influence of TC discharge on both time-integrated and time-resolved spectra, with and without TC discharge; the corresponding electron temperature and density are obtained. The results show that TC discharge significantly amplifies the spectral intensity, improving signal sensitivity in LIBS analysis. Specifically, in the laser energy range from 7.4 to 24.0 mJ, TC discharge increased the average spectral line intensities of Si (II) 385.60 nm and Si (I) 390.55 nm by factors of 8.4 and 5.1, respectively. Additionally, the average electron temperature and density were enhanced by approximately 3.2% and 4.2%, respectively, under TC discharge. The advantages of TC discharge include higher energy deposition, extended discharge duration, reduced electrode erosion, and enhanced safety. This research contributes to advancing LIBS technology and expanding its applications in various fields.

Wireless power transfer systems and wireless charging design between electric vehicles

The foundations of wireless power transmission were laid down by Nikola Tesla many years ago, by transmitting energy wirelessly using a Tesla coil. Nikola Tesla's work many years ago pioneered wireless power transmission studies today. Wireless power transmission, which telephone companies have focused on in recent years, also forms the basis for charging electric vehicles. One of the main reasons why lithium ion batteries are preferred in electric vehicles is the advantages they offer regarding the charging process. These batteries provide longer range compared to other battery types, thanks to their high energy density, that is, they can store more energy compared to their size. At the same time, faster charging capabilities are a great advantage for electric vehicle owners. As a result, charging technology is very important in electric vehicles. In this study, we will present a design project that enables electric vehicles, which have become more common in daily life with the developing technology, to transfer their charge to each other contactlessly in emergency situations. In the design, the receiver coil will be placed on the front hood of the vehicle and the transmitter coil will be placed on the rear hood of the vehicle. There will be a distance sensor where the transmitter coil is located, thanks to this sensor, the distance can be adjusted. When the vehicles reach the optimum distance, the distance sensor will give a warning and be charged enough to go to the nearest charging station. In addition, thanks to the ease of sharing for emergencies, emergency vehicles (ambulances) will be able to quickly receive energy from another vehicle and continue their duties without interruption. In this way, we will reduce the towing cost of electric and hybrid vehicles and provide drivers with uninterrupted driving. In the wireless charging station; We will offer many advantages such as getting rid of cable clutter, providing ease of use, compatibility with all devices, multiple charging and durability.

Nikola Tesla-Father of Our Energy Systems.

Nikola Tesla (1856-1943) was an American-Croatian electrical engineer who studied at Graz and Prague. He emigrated to the USA in 1884, where he worked for Thomas Edison. After a period of time, apart from having differences of opinion, Edison did not pay him the promised remuneration, so he left the job and set up on his own. Soon, Tesla promoted alternating current (AC) and invented his AC induction motor, which eliminated commutator and sparking brushes needed for direct current (DC) motors favored by Edison. During the early years of electricity, there was one problem: DC was not easily converted to higher or lower voltages. Tesla believed that AC could be converted to different voltages relatively easily using a transformer. He also made substantial improvements in the field of AC power transmission and generation, realizing that it could be generated and transmitted far more effectively than the commonly used DC. He patented his inventions and set up a partnership with George Westinghouse. His interest then shifted to developing a high-frequency and high-voltage Tesla coil with an air-core transformer, and he achieved this in 1899. He even made a device that could transmit power without intervening wires by using the earth as a transmitting oscillator. He was increasingly interested in transmitting power over large distances.

Fluorescence of BODIPY dyes in gas phase at near-ambient conditions

Molecular fluorescence is a phenomenon that is usually observed in condensed phase. It is strongly affected by molecular interactions. The study of fluorescence spectra in gas-phase can provide a nearly ideal model for the evaluation of the intrinsic properties of fluorophores. Unfortunately, most conventional fluorophores are not volatile enough to allow for the study of their fluorescence in gas phase. Here we report very bright gas phase fluorescence of simple BODIPY dyes that can be readily observed at atmospheric pressure using conventional fluorescence instrumentation. To our knowledge, this is the first example of visible-range gas-phase fluorescence at near-ambient conditions. Evaporation of the dye in vacuum allowed us to demonstrate organic molecular electroluminescence in gas discharge excited by the electric field produced by a Tesla coil.

Spark discharge-initiated radical polymerization

A new spark discharge initiated radical polymerization (SDRP) was developed. Monomer radicals were generated by spark discharge emitted from a Tesla coil as a resonant transformer generating high frequency and high voltage, and the monomer itself acted as an initiator for propagation in polymerization at the initial stage. Poly(styrene), poly(acrylonitrile), and poly(styrene)/poly(vinyl benzoate) were successfully synthesized by the SDRP. The versatile SDRP was further developed using 2,2,6,6-tetramethylpiperidine 1-oxyl free radical (TEMPO) to create dormant species to perform nitroxide-mediated-radical-polymerization. We employed d-limonene as a solvent for the SDRP because limonene can effectively dissolve the polymers. Furthermore, solitons of polyacetylene were employed as a polymerization initiator. The solutions as a carrier in polyacetylene was generated with spark discharge. This can be referred to as "soliton-initiated polymerization".

Construction and analysis of a mini Tesla coil as an educational support elemento

This article presents an assembly manual for a Tesla coil prototype using low-cost materials, developed to meet the needs of public education in Brazil. Public education in Brazil faces significant challenges, including a lack of structural and teaching resources. This makes it difficult to teach complex subjects such as Physics, which require experimental resources to understand the concepts. The Tesla coil prototype is built from low-cost materials such as acrylic, PVC, copper and electronic components. The coil has a base with 26 concentric circles, which allows vertical mobility. For qualitative analysis, the coil is used to ionize a fluorescent lamp, which turns on only when approached. For quantitative analysis, the coil is coupled to a Gaussometer, which measures the magnetic field values at different distances from the coil. In other words, we model the relationship between the distance from the sensor to the coil and the value of the measured magnetic field. Tests carried out in two public schools demonstrated that the coil is capable of arousing students' curiosity and interest in experimental Physics. The students were impressed by the effect of the electrical sparks produced by the coil, and showed interest in learning more about the concepts involved. The prototype presented is a valuable tool for teaching Physics in public high schools. The coil is affordable, easy to build and can be used to carry out experiments in Physics classes, electives and in-depth courses.

Commentary on the Process of Gravity: Quantum Mechanics and Gravity Resonance Together

In a recent paper, “The process of gravity” (2022), we developed the theory to explain gravity, stating that gravity waves are created through a process involving quantum fluctuations of all the molecules of the celestial body. The local fluctuations of adjacent molecules interact, and this process on the macroscopic scale creates the gravitational waves: at steady state, these fluctuations are structured as layers of the onion, generating a force toward the body center of mass. Here, we further develop the theory microscopically, stating that all elementary particles vibrate at their own particular frequency of gravity, generating radiant energy, where their mass determines the radiant pulses strength. These quantum fluctuations are not photons; the fluctuations are connected to the mass. These might be defined as electromagnetic radiant phonons. Yet also, the frequency of gravity might reach 10[Formula: see text]–10[Formula: see text][Formula: see text]Hz, whereas these are not photons, the energy is not high at all. This description is valid also for black holes. There, gravity waves made of electromagnetic fluctuations engulf the singularity. As these fluctuations are connected to the mass, the waves can escape the black hole, within our layering description of gravity. An anti-gravity device should create a fluctuating magnetic field and electric field, in the adequate direction, at the required frequency and strength. The signal should annihilate the Earth’s gravitation waves. In this work, an anti-gravity device is designed and developed. It is based on a Tesla coil circuit of high voltage, and high frequency, connected to a coil on a rotating board, at a condensation temperature, yet all the ingredients are replaced and improved, including the rotation feature.

3D printing of customizable and lightweight multilayer MXene/nanocellulose architectures for tunable electromagnetic interference shielding via direct ink writing

To cope with the miniaturization trend of electronic equipment, future electromagnetic interference shielding (EMI) materials need to meet the customization and flexibility on a three-dimensional (3D) scale. However, it is still a challenge for conventional manufacturing strategies to customize and design structures. Herein, we demonstrate a simple physical grinding of multilayer-MXene (m-Ti3C2Tx)/cellulose nanofibrils (CNFs) inks to print lightweight and well-conductive scaffolds by direct ink writing (DIW). The formed 3D conductive scaffolds with macro and micro pore scales exhibit an optimal EMI shielding effectiveness of about 110 dB in the X-band with a low bulk density of 139.3 mg cm−3, outperforming many reported EMI shielding materials. Meanwhile, by adjusting the ink composition, printed layer numbers, and filament spacing, it obtains a hierarchical architecture with a wide range of tunable EMI values of 6.8–110 dB. The EMI shielding effectiveness of the scaffold can reach more than 45 dB in the ultra-broadband gigahertz band (8.2–40 GHz). More importantly, a variety of printed shields matched with electronic components are constructed via DIW to simulate practical applications (Bluetooth module, Tesla coil). This work with an easy-to-manufacture approach and excellent performance provides great potential for miniaturized portable devices and GHz applications.

Plasma-Excited Nebulizer Gas-Assisted Electrospray Ionization: Enhancing the Sensitivity of Pesticide in Mass Spectrometry.

Liquid chromatography-mass spectrometry (LC-MS) is widely used in the detection of pesticide residues. However, the detection sensitivity of low-polarity pesticides by commonly used electrospray ionization may be severely suppressed, which greatly affects the limit of detection and repeatability. Herein, a plasma-excited nebulizer gas-assisted electrospray ionization (PENG-ESI) device has been developed. By introducing the discharge plasma formed by Tesla coil into the electrospray nebulizer gas channel, the sensitivity of low-polarity pesticides was significantly increased while maintaining sensitivity to polar pesticides. Under the optimized conditions, the limit of detection for S-bioallethrin was achieved at the level of 100 pg/g with good linearity (R2 > 0.99) and precision (RSD ≤ 4.61%). The matrix effect of a series of spiked matrix samples is less than 13.1%. Finally, different pyrethroid pesticide residues were successfully analyzed without separation, highlighting that the technology has potential application prospects in food quality control, environmental monitoring, and other fields.

Improving Structural MRI Preprocessing with Hybrid Transformer GANs.

Magnetic resonance imaging (MRI) is a technique that is widely used in practice to evaluate any pathologies in the human body. One of the areas of interest is the human brain. Naturally, MR images are low-resolution and contain noise due to signal interference, the patient's body's radio-frequency emissions and smaller Tesla coil counts in the machinery. There is a need to solve this problem, as MR tomographs that have the capability of capturing high-resolution images are extremely expensive and the length of the procedure to capture such images increases by the order of magnitude. Vision transformers have lately shown state-of-the-art results in super-resolution tasks; therefore, we decided to evaluate whether we can employ them for structural MRI super-resolution tasks. A literature review showed that similar methods do not focus on perceptual image quality because upscaled images are often blurry and are subjectively of poor quality. Knowing this, we propose a methodology called HR-MRI-GAN, which is a hybrid transformer generative adversarial network capable of increasing resolution and removing noise from 2D T1w MRI slice images. Experiments show that our method quantitatively outperforms other SOTA methods in terms of perceptual image quality and is capable of subjectively generalizing to unseen data. During the experiments, we additionally identified that the visual saliency-induced index metric is not applicable to MRI perceptual quality assessment and that general-purpose denoising networks are effective when removing noise from MR images.

Highly dispersed copper-iron nanoalloy enhanced electrocatalytic reduction coupled with plasma oxidation for ammonia synthesis from ubiquitous air and water

Conversion of nitrogen to ammonia at ambient conditions is a promising avenue for future distributed energy storage and fertilizer supply. However, it is currently hindered by the difficult nitrogen activation and competitive hydrogen evolution reaction. Herein, we develop a new strategy of highly dispersed copper-iron (Cu-Fe) nanoalloy enhanced electrocatalytic nitrate reduction to ammonia (NRA), in which nitrate can be derived from nitrogen and oxygen in the air via plasma process. The nitrate obtained by plasma oxidation of air is more than 3 times as much as nitrite, and the total yield rate of nitrate and nitrite is over 137 μmol·h1 by a single electrode of Tesla coil. Highly dispersed Cu-Fe nanoalloy with different ratios of Cu to Fe were prepared for NRA catalysts using the Joule heating method with instantaneous thermal shock, Cu10Fe1 nanoalloy demonstrates the best NRA activity, exhibits an excellent ammonia yield rate of 190.46 μmol·h1·cm2 and Faraday efficiency of 93.74 %. The Kelvin probe force microscope, in situ electrochemical Raman spectroscopy and density functional theory reveal the enhancing effect and tuning mechanism of Fe atom on the adsorption energy and electronic structure of Cu. This work opens up a new pathway for ammonia synthesis from air and water and provides a new strategy for the construction of high-performance NRA catalysts and the analysis of the reaction mechanism.

Inactivation of Cercospora lactucae-sativa through Application of Non-Thermal Atmospheric Pressure Gliding Arc, Tesla Coil and Dielectric Barrier Discharge Plasmas

Cercospora leaf spot disease is a serious problem for lettuce cultivation worldwide. Cercospora lactucae-sativa, the causative agent of leaf spot disease on lettuce, was treated with non-thermal atmospheric pressure gliding arc (GA), tesla coil (TC) and dielectric barrier discharge (DBD) plasmas for the in vitro fungal inactivation of both mycelial growth and conidial germination. The fungus was exposed to the three plasmas individually for 5, 10, 15 and 20 min. The results showed that DBD plasma inactivated fungal growth during all exposure periods, and the highest inhibitory effect was caused by exposure to DBD plasma for 20 min, at 93.33% inhibition. The germination of fungal conidia was completely inactivated after exposure to all three non-thermal plasmas for 5 min, as observed 4 and 24 h after incubation. The pathogenesis of C. lactucae-sativa on lettuce after plasma treatments for 5 min was examined by spraying an inoculation of the treated conidia on lettuce. The results showed that all three plasmas reduced the disease incidence and severity compared to the non-treated control. Therefore, the non-thermal atmospheric pressure GA, TC and DBD plasmas have antifungal potential for the inactivation of C. lactucae-sativa, making them an interesting novel technology for plant disease control.

Modeling and Construction of Single-Wire Power Transmission Based on Multilayer Tesla Coil

A single-wire power transmission (SWPT) system based on multilayer Tesla coil is studied in this paper. In the existing SWPT system, a single-layer Tesla coil is usually used, and the maximum transmission efficiency is only 50%-60% within a transmission distance of tens of meters. In this paper, a Tesla coil with a multilayer structure is proposed, and the connection of earth also enables the energy of the electromagnetic field to be concentrated, which can greatly improve the transmission efficiency. Moreover, considering the parasitic parameters of the multilayer coil, the circuit model of the Tesla coil is established, and the lumped parameter circuit model of the SWPT system is further obtained. Design guidance is given based on the established model. Long-distance experimental platforms have been built, various characteristics of the SWPT system such as input impedance, output power are studied. In the experiments, when transmission distance is 70 m, power of 1150 W is transmitted with efficiency of 90%. Power of 5 kW is transmitted with efficiency of 87% at transmission distance of 5 km.
