Polluted water causes more than 500,000 deaths by diarrhea a year, according to the World Health Organization (WHO). Concretely, numerous cities in Colombia suffer from water pollution by mercury due to mining, according to The Colombian Environmental Information System. Between 2003 and 2013, 1,020 tons of mercury were bought in the country for internal use.
With the objective of knowing the quality of water in remote zones of Colombia, a PhD in physics and researcher of the University of the Andes, Colombia, Jaime Andrés Pérez, collaborates in a project to assist citizens with monitoring water quality in rural zones all over Colombia. Thanks to this initiative, Pérez has become a winner in the Latin American Innovators Under 35 from the MIT Technology Review LATAM edition.
In order for the monitoring to take place, the project has four types of low cost probes. The first one can only measure the temperature and electric conductivity. The newest model, aside from the previous, is also able to take pH, diluted oxygen, turbidity measurements, apparent color, and metal concentration such as cadmium, lead, mercury, and arsenic. To avoid using batteries that could pollute the water and increase cost, the project uses probes that are nurtured by thermoelectric and piezo: nano-generators since the differences in temperature and movement of the rivers generate electricity.
Last Saturday, September 21, the first Socialization Workshop was held in the municipality of Samacá, Boyacá with the community of the project entitled: “Community platform for monitoring water quality in the Samacá-Boyacá region”.
This project is part of the 12 selected in the 794 call of 2017 made by Colciencias and part of the Boyacá Bio program, promoted by the Government of Boyacá, Colombia. The project is made up of an Alliance between the Santo Tomás University, Germán Franco Carbón S.A.S. and the University of the Andes.
The Uniandes work team is made up of the professor of the Department of Electrical and Electronic Engineering Dr. Alba Avila, Juan Manuel Alberto Lovera Lozano double degree student in Systems and Computing Engineering – Electronic Engineering and the researcher of the Department of Electrical Engineering and Electronics Dr. Jaime Andrés Pérez-Taborda.
One of the important challenges of the #4IR is to provide #energy autonomy to billions of IoT #SDG7. #Thermoelectric materials can play a key role in this. But first, it is necessary to reduce its #thermalConductivity. (SThM) is a powerful technique for thermal characterization. However, one of the most challenging aspects of thermal characterization is obtaining quantitative information on thermal conductivity with nanoscale lateral resolution.

Excelentes noticias. En su última clasificación nacional de investigadores el Ministerio de Ciencia, Tecnología e Innovación ha catalogado al profesor Jaime Andrés Pérez en su máxima categoría: Investigador Senior. Esto es especialmente importante de cara a liderar desde Research group – (NANOUPAR) Nanostructures and Applied Physics Group en la UNIVERSIDAD NACIONAL DE COLOMBIA, Sede de La Paz los proximos proyectos de largo aliento. Vamos por mas!
Desde nuestro grupo de investigación en NANOESTRUCTURAS Y FÍSICA APLICADA (#NANOUPAR) estamos interesados en hacer un ejercicio de economía circular, en el que, utilicemos materiales reciclados, botellas plásticas de alimentación (PET) básicamente, las cuales se pueden utilizar y luego triturar, para usarse de nuevo como material imprimible; la idea a mediano plazo es impulsar la creación de un Fablab en la región, en donde las propias comunidades hagan un ejercicio de reciclaje, y usen el plástico triturado para imprimir las cajas de las sondas.
Asimismo, el grupo de NANOUPAR de la Universidad Nacional de Colombia sede de La Paz seguimos investigando para proveer de una alimentación energética robusta y permanente a estas sondas portables, por medio de nanogeneradores termoeléctricos y piezoeléctricos – dispositivos pequeños que convierten la diferencia del calor y del movimiento en energía eléctrica-,respectivamente. De esta forma dar autonomía a las sondas y poder darle usos en el ecosistema del internet de las cosas (IoTs) #4RI.
¿hay investigación en inteligencia artificial para el desarrollo sostenible?
La producción de rankings internacionales de investigación, innovación y tecnología permite tener una visión general sobre las capacidades y la preparación de un país para producir y utilizar conocimiento científico. Tal es el caso del Global Innovation Index a nivel de sistemas de innovación nacionales y, en el caso de la inteligencia artificial (ia), el ranking realizado por Oxford Insights (2021), que ofrece datos sobre el uso de tecnologías de la información en el gobierno, iniciativas empresariales de ia y disposición de datos públicos.
Intense laser field effect on the D2+ molecular complex strongly confined in a semiconductor quantum ring: Electronic and optical properties
The present theoretical study is concerned with the behavior of a D2+ molecular complex strongly confined in a semiconductor quantum ring under external probes: intense laser-field radiation and orthogonal electric and magnetic fields. The theoretical calculations were made using the finite element method within the effective mass approximation. The effects of the external probes, donor-donor separation, and quantum ring geometrical parameters on the D2+ total energy, D2+ binding energy, and D2+ optical response are studied. We show that the laser-field radiation has a great influence on the two fragmentation processes of D2+ and on their essential features: equilibrium length and dissociation energy. The D2+ optical response defined through the adsorption coefficient is studied. Laser field radiation may cause red or blue shifts in the adsorption coefficient peak depending on the quantum ring size and donor-donor positions, while the magnetic field can induce an optical transparency effect.
We are very excited to share our latest publication, «Connecting brain and heart: artificial intelligence for sustainable development,» made jointly by Diego Chavarro, Jaime Andrés Pérez-Taborda, and Alba Ávila. In this article, we ask the question of whether and to what extent engineering research on artificial intelligence (AI) is focusing on sustainable development issues, and whether AI in sustainable development is helping to improve the research capabilities of low-income countries. . We find that AI research has little focus on sustainable development and that even AI research related to sustainable development shows a considerable concentration in high-income countries, with a few exceptions. If it continues like this, AI will be a technology that further increases the scientific gap between countries and will contribute little to improving our living conditions on the planet. Although it is an exploratory article, it seems to us that this is a discussion that should take place in Latin American public policy, which appears to focus on training programmers and much less on generating research capabilities on the subject of AI.
A key objective of global policies on Artificial Intelligence (AI) is to foster AI research for sustainable development (SD). In this paper, we analyze the inclusion of SD in AI research indexed by the IEEE Xplore database from 2000 to 2019. We address three critical questions: 1) To what extent is AI research addressing the sustainable development goals (SDGs)? 2) Which subject areas of AI show an emerging interest in SD? And 3) What patterns of collaboration between regions of the world are being stimulated by AI? Our scientometric analysis consists of 1) Identifying the number of AI papers that address SDGs in their titles, abstracts, and keywords. 2) Developing a composite indicator based on the number of documents produced, scientific impact, and inventive impact to distinguish areas with an emerging interest in SD; 3) Exploring co-authorship networks at three levels: region, income group, and country. The overall results show that a small share of papers is explicitly focused on SD. Our composite indicator allowed us to identify an emerging interest in SD from Ultrasonics, Ferroelectrics, and Frequency Control, Education, Consumer Electronics, Electrical Engineering, Electromagnetic Compatibility and Interference. Specifically, on AI subjects, we found emerging interests in Prediction Methods, Computation Theory, Machine Learning, Learning (artificial intelligence), and Biological Neural Networks. Inter-regional and inter-income group collaboration are limited, and network power is concentrated in a few countries. The results could be useful to improve the connection between technical knowledge, strategic planning for S&T investment, and SD policies.
