MIT Innovator LATAM and VISIONARY of the YEAR |

Dr. Jaime Andrés Pérez Taborda, from Colombia, was recognized as “Visionary of the Year”  for his collaborative project to monitor water quality in remote communities, holding private businesses and governmental institutions responsible for their water waste.

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.

New publication in ACS Omega

We are very proud to share our latest paper Polyethyleneimine-Functionalized Carbon Nanotube/Graphene Oxide Composite: A Novel Sensing Platform for Pb(II) Acetate in Aqueous Solution (https://pubs.acs.org/doi/10.1021/acsomega.1c02085)

#HeavyMetal pollution is posing a severe health risk on living organisms. Therefore, significant research efforts are focused on their detection. Here, we developed a sensing platform #sensor for the selective detection of lead(II) acetate. The sensor is based on self-assembled polyethyleneimine-functionalized carbon nanotubes (PEI-CNTs) and graphene oxide films deposited onto gold interdigitated electrodes. The graphene-based nanostructure showed a resistive behavior, and the fabricated layer-by-layer film was used to detect Pb(II) acetate in an aqueous solution by comparison of three electrochemical methods: impedance spectroscopy, amperometry, and potentiometry stripping analysis. The results obtained from different methods show that the detection limit was down to 36 pmol/L and the sensitivity up to 4.3 μAL/μmol, with excellent repeatability. The detection mechanism was associated with the high affinity of heavy metal ions with the functional groups present in the PEI-CNTs and GO, allowing high performance and sensitivity. The achieved results are important for the research toward integrated monitoring and sensing platforms for Pb(II) contamination in drinking #water#SDG6. Made with ♡ from #Colombia

Connecting Brain and Heart: Artificial Intelligence for Sustainable Development:
A key objective of global policies on Artificial Intelligence (AI) is to foster AI research for sustainable development (SD). In this paper we examine the inclusion of this objective in AI published research by addressing three 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? We analyzed AI papers from 2000 to 2019 using the IEEE Xplore database by:
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, citation impact, and inventive impact to distinguish areas with an emerging interest in SD; 3) Exploring co-authorships at three levels: region, income group, and country. 10.31235/osf.io/gj5kr

ZnO/PDMS nanocomposite generator: Interphase influence in the nanocomposite electro-mechanical properties and output voltage

Nanocomposite generators convert mechanical energy into electrical energy and are attractive low-power solutions for self-powered sensors and wearables. Homogeneous dispersion, high concentration, and orientation of the embedded filler strategies have been assumed to maximize the voltage output in nanocomposite generators. This work contrast these assumptions by studying the dominance of the interphase in low filler concentrations (¡ 10%) and random dispersions in a ZnO/PDMS nanocomposite generator with high peak-to-peak voltage generation capabilities (≈ 150 V). The interphase in the nanocomposite was studied by the analysis of the random dispersion of the nanocomposite through the estimation of the effective volume fraction (ϕ a g g) which allowed us to identify three levels of interaction: individual interphases, interacting interphases, and overlapping between NPs and interphases.

Podcast: Water and Life

According to data from the World Health Organization el inadequate management of urban, industrial, and agricultural wastewater means the drinking-water of hundreds of millions of people is dangerously contaminated or chemically polluted.

Some 829 000 people are estimated to die each year from diarrhoea as a result of unsafe drinking-water, sanitation, and hand hygiene. Yet diarrhoea is largely preventable, and the deaths of 297 000 children aged under 5 years could be avoided each year if these risk factors were addressed.

National Physical Engineering Week – 2020

Bienvenida/Welcome

“Have no respect whatsoever for authority; forget who said it and instead look what he starts with, where he ends up, and ask yourself, “Is it reasonable?” –
What Do You Care What Other People Think? (1988) –  Richard Feynman

La autoridad, los dogmas, lo establecido el statu quo por un lado. El enfoque autocrítico, el razonamiento, la disrupción, el cambio permanente en contraste. Son facetas de nuestra actual sociedad y de los tiempos en pandemia. En 1965, el físico estadounidense Richard Feynman recibió el Premio Nobel de Física junto a Julian Schwinger y Shin’ichirō Tomonaga. En la actualidad, Feynman es recordado con especial cariño por varias generaciones que vemos en su genialidad y rebeldía el modelo de científico de estas épocas.

Inspirados por ese espíritu curioso, transformador y provocador que alberga la ciencia, hemos convocado la Semana Nacional de la Ingeniería Física 2020 (SNIF) en donde esperamos propiciar un tiempo y espacio de encuentro virtual entre profesionales de diversas áreas de la ingeniería y de las ciencias naturales. La Sociedad Colombiana de Ingeniería Física (SCIF) es una asociación científica, civil sin ánimo de lucro que durante los últimos 10 años ha promovido la interacción con la comunidad académica nacional e internacional a través de 6 congresos nacionales e internacionales, foros y actividades de índole cultural, científicas y académicas. El principal interés de la SCIF es el fomento en investigación aplicada al mejoramiento de la calidad de vida de todas y todos. El estudio, y la divulgación del conocimiento de la física y sus aplicaciones como medio eficaz para el progreso académico y científico del país son prioridad.

Las actividades de la Semana Nacional de la Ingeniería Física son gratuitas y han estado a cargo de los capítulos de estudiantes de la Sociedad Colombiana de Ingeniería Física quienes, con una variada programación, nos proponen actividades académicas, culturales y científicas a lo largo de la semana. Esta apuesta de resiliencia nos recuerda el compromiso que como profesionales tenemos con la sociedad en todo su conjunto. Las actividades han sido organizadas por días y pueden ser consultadas acá:
