    Furfural adsorption on V2O5 surface: A combined experimental-theoretical study
    (Elsevier, 2024-06-16) Lizana, Ignacio
    The adsorption of furfural on the V2O5 surface was investigated using experimental and theoretical methods. In situ Diffuse Reflectance Infrared Fourier-Transform Spectroscopy results show the presence of physi- and chemi-sorption phenomena, where trans-furfural is mostly chemisorbed at the beginning of the adsorption process. These results are in agreement with theoretical DFT results, as the most thermodynamically favored configurations corresponds to the chemisorbed trans-furfural (T1) and cis-furfural (C1) with binding energies of −1.83 and −2.05 eV.

    Sustaining business performance management: an operational framework
    (Elsevier, 2023-01-01) Yanine, Fernando
    This article explores an increasingly important theme for all business sectors: sustainability and its linkage to business performance management, and proposes an operational framework based on the Balanced Scorecard model. Enterprise sustainability is a subject that is extensively being assessed and measured in various industries nowadays. We focus on Chilean SMEs and explore how a sustainability trend led by technology-related innovation and performance measurement systems can enable and allow to maintain sustainable enterprises through the today's volatile, uncertain and complex socio political and economic scenario. Worldwide, issues such as sustainability, innovation and social responsibility are driving business performance management (BPM) of thriving companies, many of which champion for greater social equity, business sustainability and fairness. This process entails a paradigm shift that is particularly noticeable in small and medium size enterprises or SMEs―the largest segment of Latin America's businesses, and especially so in Chile, a country which, according to OECD 2022’s Table 8.2. Distribution of firms in Chile, 2018, SMEs account for over 90% of the enterprises in the country.

    Tailoring of titanium dioxide thin film in dual radiofrequency plasma enhanced pulsed laser deposition
    (Elsevier, 2025-06-20) Villegas, Rodrigo
    Efficient and cost-effective methods to create photovoltaic materials are constantly being sought, with metal oxides like TiO2 playing a key role in this field. In this study, TiO2 thin films were grown on glass substrates using a dual radiofrequency (RF) plasma-enhanced pulsed laser deposition (PLD) system with a thermal budget that remained below 400 ◦C. The physical, chemical, and optical properties of the deposited thin films were studied as a function of low- and high-RF powers as well as deposition time. These parameters were found to impact the proportion of anatase and rutile phase and their crystallinity, as well as the oxygen vacancy concentration and band gap energy. These findings demonstrated the utility of dual RF plasma-enhanced PLD for precise modulation of TiO2 thin-films, offering promising applications in photovoltaics and photocatalysis.
