Dextran aldehyde (dexOx), resulting from the periodate oxidative cleavage of 1,2-diol moiety inside dextran, is a polymer that is very useful in many areas, including as a macromolecular carrier for drug delivery and other biomedical applications. In particular, it has been widely used for chemical engineering of enzymes, with the aim of designing better biocatalysts that possess improved catalytic properties, making them more stable and/or active for different catalytic reactions. This polymer possesses a very flexible hydrophilic structure, which becomes inert after chemical reduction; therefore, dexOx comes to be highly versatile in a biocatalyst design. This paper presents an overview of the multiple applications of dexOx in applied biocatalysis, e.g., to modulate the adsorption of biomolecules on carrier surfaces in affinity chromatography and biosensors design, to serve as a spacer arm between a ligand and the support in biomacromolecule immobilization procedures or to generat...

RESUMEN. Se plantea al alumnado el analisis de la huella de carbono que tiene, en la actualidad, la asignatura practica Experimentacion en Quimica Inorganica, con el objetivo de que busquen las posibilidades de sustitucion y/o reduccion de reactivos toxicos y peligrosos en las practicas de laboratorio que se imparten. Previamente, en base a dicho analisis, la red ha redactado las directrices que guiaran al alumno en sus busquedas en bases de datos y su proposicion de sustitucion razonada de reactivos. Cada grupo de alumnos que trabaja en un proyecto particular de “Sintesis y caracterizacion de sustancias inorganicas”, redacta un protocolo de actuacion para eliminar/reducir el uso de reactivos peligrosos/contaminantes en su proyecto. Como colofon, se redacta un protocolo global para hacer mas sostenible el proceso de ensenanza/aprendizaje de esta asignatura practica. Ademas de trabajar el contenido especifico de la asignatura, con esta metodologia de aprendizaje, se pretende aumentar...

In this account the most relevant advancements in hydrogen storage in porous materials are presented. These include the current state‐of‐the‐art, the challenges which have been overcome, and the hurdles which still remain. The most important milestones which will be discussed in this work will be the development of new apparatuses capable of delivering reliable results under a broad range of operational conditions, in which analysis temperature and pressure are critical parameters. Other aspects such as the materials storage capacity in gravimetric and volumetric terms will be critically discussed to identify the conditions required from an ideal material. Finally, different upgrade possibilities from modifying the adsorbate‐adsorbent interaction to using rigid or flexible materials will be presented and put into perspective with current literature.

Ó The Author(s) 2010. This article is published with open access at Springerlink.com Abstract ZnO nanowires have been grown by chemical vapour deposition (CVD) using PdZn bimetallic nanoparticles to catalyse the process. Nanocatalyst particles with mean particle diameters of 2.6 ± 0.3 nm were shown to catalyse the growth process, displaying activities that compare well with those reported for sputtered systems. Since nanowire diameters are linked to catalyst morphology, the size-control we are able to exhibit during particle preparation represents an advantage over existing approaches in terms of controlling nanowire dimensions, which is necessary in order to utilize the nanowires for catalytic or electrical applications.

The elimination of volatile organic compounds (VOCs) at low concentration is a subject of great interest because these compounds are very harmful for the environment and human health. In this work, we have developed a synthesis methodology of TiO2 that allows obtaining meso-macroporous materials with hierarchical porosity and with high thermal stability for their application as photocatalysts in the removal of VOCs, specifically propene. The materials synthesized in this work were characterized by Scanning electron microscope (SEM), Transmission electron microscopy (TEM), powder X-ray diffraction (XRD), Thermogravimetric Analysis (TG), and nitrogen adsorption. It is observed that the samples calcined at 250 °C and 500 °C present a high photoactivity for the photooxidation of propene, which is similar to the benchmark material P25 (commercial TiO2). Moreover, the textural properties are better than those for P25, indicating that the samples are interesting for the preparation of phot...

The study habits of millennial students are quite different from the students of past times. The new university student generations will need new teaching approaches adapted to their technological skills, with lap tops, tablets, smartphones, and so on, as tools for learning as its own pace, everywhere. In this communication, the adaptation of a collection of study materials, used in an Inorganic Chemistry Foundations topic, for their use in mobile learning and/or BYOD (Bring Your Own Device) strategy is presented. The materials are suited for the understanding of inorganic crystalline solids which, having crystalline structures (long range order), seem so difficult to visualize with 2D figures, as to understand their structural characteristics. The format of these materials was initially in PDF documents with 2D figures used for constructing models with little balls, following the steps in the text, on-site class in the laboratory. Later, the use of web pages with Java applets, running with JMol, introduced the students in a 3D visualization of the structure; clicking the different applet buttons student discovers the inner structure of the crystalline inorganic solids step by step. Both types of materials have been now brought up to date so that students would use them not only on-site classroom but also in every other time and place. Because JMol with Java doesn’t run in mobile devices, it has been necessary to use JSMol and also re-write the HTML5 (HyperText Markup Language) code and CSS (Cascading Style Sheet) following the RWD (Responsive Web Design) approach. Programming the website to automatically respond to the user’s preferences, it can be switching continuously image size and scripting abilities to accommodate for resolution, depending on the device used.
