Temporal and energetic scale of solid matter interaction phenomena occurring during femtosecond ablation of solids
(2013-11-22)Ablation using femtosecond lasers exhibits significant differences with that at the nanosecond timescale, where the concurrence of photochemical and photothermal processes taking place during the photon absorption govern ... -
Temporal evolution of surfaces on materials after femtosecond laser irradiation: The earliest stages (Oral presentation)
(2015-10-26)Ablation using femtosecond lasers exhibits significant differences in comparison with the nanosecond timescales. Ultrashort laser-matter interaction provides the observation of different phenomena as there is neither ... -
The sources, progress and frontiers of an exciting technology: Laser-Induced Breakdown Spectroscopy
(2017-07-11)Laser induced breakdown spectroscopy (LIBS) is currently considered one of the most active research areas in the field of analytical spectroscopy. LIBS has emerged as a powerful alternative for chemical analysis in a wide ... -
The use of simulations and videos in order to improve the learning of REDOX reactions in Engineering Degrees
(2016-11-21)Many students from secondary schools to universities in many countries struggle to learn chemistry and many do not succeed. Many high school and university students experience difficulties with fundamental ideas in chemistry ... -
The use of YouTube in Chemistry classes to motivate students.
(2023)This communication describes an educational practice developed in the Chemistry subject, of the first year of the Degree in Electrical Engineering (University of Malaga, Spain). Based on the selection of a series of ... -

(2022)The SuperCam instrument of the NASA MARS 2020 Perseverance rover combines a suite of atomic and molecular spectroscopies intended for an extensive description of rocks, soils and minerals in the surroundings of the landing ... -
Use of a new enrichment nanosorbent for speciation of mercury by FI-CV-ICP-MS
(2015-07-20)Mercury is one of the most toxic environmental pollutants and its effects on human and ecosystem health are well known. All mercury species are toxic, with organic mercury compounds generally being more toxic than inorganic ... -
The use of flipped classroom to learn a new language at the University
(2020-03-30)The Flipped Classroom model consists on a type of blended learning that reverses the traditional learning environment by delivering instructional content outside of the classroom and usually on line. Most descriptions of ... -
Using a periodic table multimedia in order to simplify a new universal language, the chemical language
(2014-11-17)There is a little bit analogy between chemistry and foreign languages. Most languages have different alphabets for each one. In order to learn a second language, one needs to know the new symbols. In chemical language, ... -
