A 68 ka precipitation record from the hyperarid core of the Atacama Desert in northern Chile
(Elsevier, 2020-01)[Abstract] The Atacama Desert in northern Chile is one of the driest deserts on Earth. Hyperaridity persists at least since the Miocene and was punctuated by pluvial phases. However, very little is known about the timing, ... -
A Bio-inspired Hypoxia Sensor using HIF1a-Oxygen-Dependent Degradation Domain
(Nature, 2019-05-08)[Abstract] Functional imaging has become an important tool in oncology because it not only provides information about the size and localization of the tumour, but also about the pathophysiological features of the tumoural ... -
A capillary zone electrophoresis for determination of thiolic peptides in biological samples
(WILEY-VCH Verlag, 2009-06)A new method to improve the analyses of thiolic peptides (cysteine, γGlu-Cys, glutathione, phytochelatins and desglycyl-phytochelatins) derivatized with monobromobimane (mBrB) in complex biological samples by CZE is ... -
A combined NMR and DFT study of conformational dynamics in lanthanide complexes of macrocyclic DOTA-like ligands
(Royal Society of Chemistry, 2017-09-06)[Abstract] The solution dynamics of the Eu(III) complexes of H4dota (1,4,7,10-tetraazacyclododecane-1,4,7,10-tetracarboxylic acid) and H5do3ap (1,4,7,10-tetraazacyclododecane-4,7,10-tris(carboxymethyl)-1-methylphosphonic ... -
A Comparative Study of Physical and Chemical Processes for Removal of Biomass in Biofilters
(MDPI, 2011-08)After 6 months of operation a long-term biofilter was stopped for two weeks and then it was started up again for a second experimental period of almost 1.3 years, with high toluene loads and submitted to several physical ... -
A Comparison of the Relative Sensitivity of Structural and Functional Cellular Responses in the Alga Chlamydomonas eugametos Exposed to the Herbicide Paraquat
(Springer, 1999-04)The effect of the herbicide paraquat on the freshwater microalga Chlamydomonas eugametos was studied in function of different parameters such as growth, elemental composition, total lipids, and photosynthetic pigments ... -
A Further Step Towards the Characterisation of Terebellides (Annelida, Trichobranchidae) Diversity in the Northeast Atlantic, With the Description of a New Species
(Pensoft, 2022-11-28)[Abstract] Several new species of genus Terebellides Sars, 1835 (Annelida, Trichobranchidae) have been recently described from the Northeast Atlantic Ocean after the detection of a large complex of species based on DNA ... -
A further study of acetylacetone nitrosation
(Royal Society of Chemistry, 2013-02)The nitrosation of acetylacetone (AcAc) has been revised in an aqueous acid medium of perchloric acid and buffers of mono-, di-, or tri-chloroacetic acid. The results show that in the presence of buffers, under conditions ... -
A GIS-supported Multidisciplinary Database for the Management of UNESCO Global Geoparks: the Courel Mountains Geopark (Spain)
(Springer Nature, 2022-03-18)[Abstract] The management of a UNESCO Global Geopark (UGGp) requires a vast wealth of miscellaneous scientific knowledge that can be successfully organised using a Geographical Information System (GIS). This paper presents ... -
A Green Approach for the Automatic Quantitative Analysis of Additives in Plastic Samples Using In-Tube Extraction Dynamic Headspace Sampling Technique Coupled to GC-MS/MS
(Elsevier, 2024-05-08)[Abstract] Background: Many of the chemicals frequently used as additives have been recognised as hazardous substances, and therefore their analysis is necessary to evaluate plastic contamination risk. Additives analysis ... -
A Low-Cost System to Simulate Environmental Microplastic Weathering
(Elsevier, 2019-12)[Abstract] Society concerns about the potential thread of microplastics into the environment call for detailed laboratory and field studies to assess their fate, in particular, their weathering. This can hardly be done in ... -
A mega-cryptic species complex hidden among one of the most common annelids in the North East Atlantic
