Cleanrooms

Cleanrooms are isolated rooms or chambers designed to limit airborne particles as well as separate hazardous particles from more everyday spaces. They are used in a variety of fields, including life sciences, but in materials science they are largely used in the electronics industry. Cleanrooms are rated and classified based on the size and quantity of particles that they remove from the air. Because people carry and create airborne particles themselves, significant PPE is required before entering a cleanroom.

The Promise Of Microwave-Based Plasma Systems

In the realm of advanced manufacturing and material processing, innovation often emerges from the convergence of diverse disciplines. Microwave-based plasma systems represent a prime example of such interdisciplinary synergy, offering a versatile and efficient approach to a wide range of industrial applications. From surface modification and thin film deposition to nanomaterial synthesis and waste treatment, these systems harness the power of plasma generated by microwaves to enable precision engineering at the atomic level. In this article, we delve into the fundamentals of microwave-based plasma systems, explore its diverse applications, and envision its transformative potential in shaping the future of materials science and manufacturing.

Understanding Microwave-Based Plasma Systems:

At the heart of microwave-based plasma systems lies the principle of plasma generation through the interaction of electromagnetic fields with gas molecules. Unlike traditional plasma sources, such as radiofrequency (RF) or direct current (DC) discharges, microwave-based plasma systems leverage the unique properties of microwaves to achieve higher plasma densities, lower operating pressures, and enhanced energy transfer efficiency. This enables precise control over plasma parameters, such as temperature, composition, and spatial distribution, facilitating tailored material processing with unparalleled precision and reproducibility.

The core components of a microwave-based plasma system typically include a microwave generator, waveguide, plasma chamber, and process control unit. The microwave generator produces high-power microwaves at frequencies ranging from gigahertz to terahertz, which are then coupled into the plasma chamber through a waveguide. Within the chamber, the microwaves interact with the process gas, ionizing it and initiating plasma discharge. Advanced control algorithms govern the system operation, regulating parameters such as microwave power, gas flow rate, and pressure to achieve desired processing outcomes.

Applications Across Industries:

Microwave-based plasma systems find widespread application across diverse industries, spanning materials science, semiconductor manufacturing, aerospace, energy, and environmental remediation. One of the primary applications is surface modification, wherein plasma treatment alters the chemical composition and morphology of material surfaces to enhance adhesion, wettability, and biocompatibility. This technique is extensively employed in the production of biomedical implants, electronic devices, and functional coatings.

Moreover, microwave-based plasma system-enhanced chemical vapor deposition (PECVD) enables the deposition of thin films with exceptional uniformity, purity, and adherence. This process is indispensable in semiconductor fabrication, where it is utilized for the deposition of silicon dioxide, silicon nitride, and other dielectric and conductive films in integrated circuit manufacturing. Additionally, microwave plasma systems facilitate the synthesis of nanomaterials, including nanoparticles, nanowires, and quantum dots, through controlled gas-phase reactions and nucleation processes.

In the aerospace and automotive industries, microwave-based plasma technology offers novel solutions for surface cleaning, coating removal, and thermal barrier coating deposition. Plasma cleaning effectively removes contaminants, oxides, and organic residues from metal, ceramic, and polymer surfaces, ensuring optimal adhesion and performance of subsequent coatings or adhesive bonds. Furthermore, the deposition of thermal barrier coatings using plasma spraying enhances the durability and heat resistance of engine components, contributing to improved fuel efficiency and engine lifespan.

Emerging Frontiers and Future Prospects:

As the pace of technological innovation accelerates, microwave-based plasma systems continue to push the boundaries of possibility in materials processing and nanotechnology. Advancements in plasma chemistry, reactor design, and process monitoring are enabling the development of novel materials with tailored properties and functionalities, revolutionizing fields such as optoelectronics, energy storage, and catalysis.

Furthermore, the integration of artificial intelligence and machine learning algorithms into plasma processing workflows holds the promise of autonomous optimization and adaptive control, enhancing process efficiency, yield, and reliability. Real-time diagnostics and in-situ characterization techniques, such as optical emission spectroscopy and mass spectrometry, provide valuable insights into plasma kinetics and reaction pathways, enabling precise process control and predictive modeling.

In the realm of environmental sustainability, microwave-based plasma systems offer innovative solutions for waste treatment, pollution remediation, and resource recovery. Plasma-assisted gasification and pyrolysis processes enable the conversion of organic waste into syngas or biochar, reducing landfill volumes and mitigating greenhouse gas emissions. Additionally, plasma catalysis holds the potential for the degradation of organic pollutants and the synthesis of value-added chemicals from waste streams, contributing to the circular economy and resource conservation.

Conclusion:

Microwave-based plasma systems represent a paradigm shift in materials processing, offering unparalleled versatility, precision, and efficiency across a spectrum of industrial applications. From surface modification and thin film deposition to nanomaterial synthesis and environmental remediation, these systems embody the convergence of advanced plasma physics, materials science, and engineering innovation. As research and development efforts continue to expand the frontiers of plasma technology, the transformative impact of microwave-based plasma systems on manufacturing, energy, and sustainability promises to shape the future of industry and society.

Evaluation of delivery costs for external beam radiation therapy and brachytherapy for locally advanced cervical cancer using time-driven activity-based costing

Publication date: Available online 14 September 2017 Source:International Journal of Radiation Oncology*Biology*Physics Author(s): Kristine Bauer-Nilsen, Colin Hill, Daniel M. Trifiletti, Bruce Libby, Donna H. Lash, Melody Lain, Deborah Christodoulou, Constance Hodge, Timothy N. Showalter PurposeThis study aims to evaluate the delivery costs, using time-driven activity-based costing (TDABC), and reimbursement for definitive radiation therapy for locally advanced cervical cancer.Methods and MaterialsProcess maps were created to represent each step of the radiation treatment process and included personnel, equipment, and consumable supplies used to deliver care. Personnel were interviewed to estimate time involved to deliver care. Salary data, equipment purchasing information and facilities costs were also obtained. We defined the capacity cost rate (CCR) for each resource, and then calculated the total cost of patient care based upon CCR and time for each resource. Costs were compared to 2016 Medicare reimbursement and relative value units (RVUs).ResultsThe total cost of radiation therapy for cervical cancer was $12,861.68, with personnel costs comprising 49.8%. Brachytherapy cost $8,610.68 (66.9% of total) and consumed 423 minutes of attending radiation oncologist time (80.0% of total). EBRT cost $4,055.01 in costs (31.5% of total). Personnel costs were higher for brachytherapy than for the sum of simulation and EBRT delivery ($4,798.73 vs. $1,404.72). A full radiation therapy course provides radiation oncologists 149.77 RVUs with IMRT or 135.90 RVUs with 3DCRT, with total reimbursement of $23,321.71 and $16,071.90 respectively. Attending time per RVU is approximately 4-fold higher for brachytherapy (5.68 minutes) than 3DCRT (1.63 minutes) or IMRT (1.32 minutes).ConclusionTDABC was used to calculate the total cost of definitive radiation therapy for cervical cancer, revealing that brachytherapy delivery and personnel resources comprised the majority of costs. However, current reimbursement policy does not reflect the increased attending physician effort and delivery costs of brachytherapy. We hypothesize that the significant discrepancy between treatment costs and physician effort versus reimbursement may be a potential driver of reported national trends towards poor compliance with brachytherapy and suggest re-evaluation of payment policies to incentivize quality care.

Teaser

Time-driven activity-based costing methodology was applied to calculate the delivery costs of definitive radiation therapy for locally advanced cervical cancer. Brachytherapy was more costly and consumed more attending radiation oncologist time than external beam radiation therapy. Comparison of the delivery costs and physician time requirements to current reimbursement revealed a financial disincentive against brachytherapy, which should be studied as a potential contributor to the reported national poor compliance rates for cervical cancer brachytherapy. http://ift.tt/2fni2eh

Failure modes and effects analysis for ocular brachytherapy

Publication date: Available online 18 August 2017 Source:Brachytherapy Author(s): Yongsook C. Lee, Yongbok Kim, Jason Wei-Yeong Huynh, Russell J. Hamilton PurposeThe aim of the study was to identify potential failure modes (FMs) having a high risk and to improve our current quality management (QM) program in Collaborative Ocular Melanoma Study (COMS) ocular brachytherapy by undertaking a failure modes and effects analysis (FMEA) and a fault tree analysis (FTA).Methods and MaterialsProcess mapping and FMEA were performed for COMS ocular brachytherapy. For all FMs identified in FMEA, risk priority numbers (RPNs) were determined by assigning and multiplying occurrence, severity, and lack of detectability values, each ranging from 1 to 10. FTA was performed for the major process that had the highest ranked FM.ResultsTwelve major processes, 121 sub-process steps, 188 potential FMs, and 209 possible causes were identified. For 188 FMs, RPN scores ranged from 1.0 to 236.1. The plaque assembly process had the highest ranked FM. The majority of FMs were attributable to human failure (85.6%), and medical physicist–related failures were the most numerous (58.9% of all causes). After FMEA, additional QM methods were included for the top 10 FMs and 6 FMs with severity values > 9.0. As a result, for these 16 FMs and the 5 major processes involved, quality control steps were increased from 8 (50%) to 15 (93.8%), and major processes having quality assurance steps were increased from 2 to 4.ConclusionsTo reduce high risk in current clinical practice, we proposed QM methods. They mainly include a check or verification of procedures/steps and the use of checklists for both ophthalmology and radiation oncology staff, and intraoperative ultrasound-guided plaque positioning for ophthalmology staff.
