“…Indeed, COVID-19 has the ability to not only spread via close-contact, but also through unclean surfaces; it can persist on inanimate surfaces-metal, glass, or plastic-for days [77]. Therefore, surfaces and objects need to be sterilised; sterilisation kills all forms of microbial life on an object or surface [78].…”

Traditionally, advances in robotic technology have been in the manufacturing industry due to the need for collaborative robots. However, this is not the case in the service sectors, especially in the healthcare sector. The lack of emphasis put on the healthcare sector has led to new opportunities in developing service robots that aid patients with illnesses, cognition challenges and disabilities. Furthermore, the COVID-19 pandemic has acted as a catalyst for the development of service robots in the healthcare sector in an attempt to overcome the difficulties and hardships caused by this virus. The use of service robots are advantageous as they not only prevent the spread of infection, and reduce human error but they also allow front-line staff to reduce direct contact, focusing their attention on higher priority tasks and creating separation from direct exposure to infection. This paper presents a review of various types of robotic technologies and their uses in the healthcare sector. The reviewed technologies are a collaboration between academia and the healthcare industry, demonstrating the research and testing needed in the creation of service robots before they can be deployed in real-world applications and use cases. We focus on how robots can provide benefits to patients, healthcare workers, customers, and organisations during the COVID-19 pandemic. Furthermore, we investigate the emerging focal issues of effective cleaning, logistics of patients and supplies, reduction of human errors, and remote monitoring of patients to increase system capacity, efficiency, resource equality in hospitals, and related healthcare environments.

“…Pero son muchas más las aplicaciones que se le pueden dar a una instalación de este tipo; entre ellas se encuentra el uso de la radiación como catalizador en reacciones de polimerización [28], conservación del patrimonio cultural [29], tratamiento de aguas residuales [30], mutaciones benéficas de especies vegetales [31] y técnica del macho estéril para control de moscas de la fruta [32], [33]. Las fuentes son almacenadas en una piscina profunda que actúa como blindaje biológico, impidiendo que la radiación escape; por lo demás, no hay activación alguna del agua [25]. En comparación con otras tecnologías de irradiación, como los rayos X y los electrones acelerados, los rayos gamma tienen mayor penetrabilidad y su producción depende de un isótopo que decae naturalmente, y no de máquinas que consumen energía para su operación [25].…”

La irradiación gamma es un método seguro y efectivo de control de microorganismos dañinosy patógenos en diferentes clases de productos que los humanos consumen en todo elmundo, sean alimentos o productos de farmacia, cosmética y dispositivos médicos. La irradiacióngamma de alimentos se utiliza principalmente con el fin de lograr su preservaciónmediante la reducción del deterioro, el mejoramiento de su higiene y el aumento de su vidaútil. Son varias las aplicaciones en la industria alimentaria, que van desde desinfestaciónde frutas y semillas, inhibición de brotes en tubérculos, conservación y desinfección, hastaesterilización, de todas las cuales derivan múltiples beneficios; cada una suple una necesidadque otras tecnologías no satisfacen totalmente, lo cual genera un menor impacto económicoy ambiental. A pesar de su importante aporte a la preservación e inocuidad de los alimentos,en el ámbito nacional no se aplica la tecnología de irradiación en las cadenas de produccióny se desconocen los efectos específicos de la técnica sobre la calidad de los productos locales,así como las características inherentes de posibles productos irradiados que entran al país,a lo cual se suma una desconsiderada falta de regulación que respalde su explotación segura.

“…The high energy electron beam (EB) has become a powerful and important tool to modify the physico-chemical characteristics of both the categories of organic semiconductors namely molecular semiconductor and conducting polymer. The amount of radiant energy absorbed per unit mass of the material, is known as radiation dose (D), which is measured in joules per kg and its unit is gray (Gy) [1,2]. EB processing is a type of radiation treatment in which an accelerator is used to generate high energy electron beam and this EB is made to fall on the material of interest for their modifications.…”

Electron Beam Induced Tailoring of Electrical Characteristics of Organic Semiconductor Films

et al. 2020

Tailoring the characteristics of organic semiconductors including molecular semiconductor and conducting polymers is the frontline area of research for improving the performance of organic electronic devices. Electron beam treatment has been established as one of the easiest method in comparison to others like chemical doping, thermal processing, ozonolysis, UV and other ionizing radiation treatment, to tune the physico-chemical properties of organic semiconductors. High energy electron beam (EB) generated from an accelerators impinges energy to the material and causes several phenomena including doping, crosslinking, chain degradation, gas evolution, molecular structural modifications, oxidation and unsaturation. Such modifications lead to variation in electrical characteristics and consequently affect the overall device performances. In the present review we have focused on the different interaction processes of EB with organic semiconductors and its implications to tailor the performance of device comprising of it mainly gas sensors, field effect transistors, thermoelectric power generators and radiation dosimeters.
