Progress and perspectives on pillared clays applied in energetic and environmental remediation processes
Pillared interlayered clays (PILCs) are materials that show a two-dimensional layered porous structure with properties that could be interesting alternatives to zeolites and other microporous solids. Some of the properties ... -
Progress and recent strategies in the synthesis and catalytic applications of perovskites based on lanthanum and aluminum
Lanthanum aluminate-based perovskite (LaAlO3) has excellent stability at high temperatures, low toxicity, and high chemical resistance and also offers wide versatility to the substitution of La3+ and Al3+, thus, allowing ... -
Progress in the removal of pharmaceutical compounds from aqueous solution using layered double hydroxides as adsorbents: a review
Emerging contaminants and, among them, pharmaceutical compounds, have a significant impact on water ecosystems. Layered Double Hydroxides (LDH), being easy to synthesize and cheap materials, have recently gained attention ... -
Progress in the synthesis and applications of hexaaluminate-based catalysts
The development of materials that can exhibit thermal resistance at very high temperatures, thus allowing them to be applied as catalysts and thermal insulators, amongst other possible uses, is a research subject of great ... -
Propuesta de rehabilitación ambiental del Lago Uru Uru
(Instituto de Investigaciones Mineras, Universidad Técnica de Oruro (Bolivia), 2021) Artículo / ArtikuluaDurante varios siglos, la industria minera y de procesamiento de minerales ha sido la base de la economía del departamento de Oruro en Bolivia, y aparentemente, continuará siéndolo en un futuro previsible. Estas labores, ... -
The proteome of Medicago truncatula in response to ammonium and urea nutrition reveals the role of membrane proteins and enzymes of root lignification
Plants differ widely in their growth and tolerance responses to ammonium and urea nutrition, while derived phenotypes seem markedly different from plants grown under nitrate supply. Plant responses to N sources are complex, ... -
Pseudo-homogeneous and heterogeneous kinetic models of the NaOH-catalyzed methanolysis reaction for biodiesel production
Methanolysis of vegetable oils in the presence of homogeneous catalysts remains the most important process for producing biodiesel. However, there is still a lack of accurate description of the reaction kinetics. This is ... -
Pyric herbivory increases soil microbial diversity but has a site-dependent effect on soil mesofauna in the mid-term
Woody plant encroachment threatens grassland biomes at a global scale. Pyric herbivory combines prescribed burnings and targeted grazing to restore open habitats and has proved to be successful in promoting landscape and ... -
Reaction monitoring by ultrasounds in a pseudohomogeneous medium: triglyceride ethanolysis for biodiesel production
The sound propagation speed measurement us is used for monitoring triglyceride ethanol-ysis in a broad range of reaction conditions (mainly, temperature: 23–50◦C; ethanol/oil: from 6 to 24 mol/mol). Experimentally, us ... -
Recent advances in bromine complexing agents for zinc-bromine redox flow batteries
The development of energy storage systems (ESS) has become an important area of research due to the need to replace the use of fossil fuels with clean energy. Redox flow batteries (RFBs) provide interesting features, such ... -
Recognizing the importance of an urban soil in an open-air city museum: An opportunity in the city of Madrid, Spain
This article examines the presence of urban soil buried under anthropogenic debris in an air-museum park in the Madrid city center (Spain), and highlights the particularities of this singular urbanized setting to indicate ... -
Reducing SO₂ doses in red wines by using grape stem extracts as antioxidants
SO₂ is a very important wine preservative. However, there are several drawbacks associated with the use of SO₂ in wine. The aim of this work is to evaluate the effect of the partial substitution of SO₂ in the Tempranillo ... -
The regulators of peroxisomal acyl-carnitine shuttle CROT and CRAT promote metastasis in melanoma
Circulating tumor cells are the key link between a primary tumor and distant metastases, but once in the bloodstream, loss of adhesion induces cell death. To identify the mechanisms relevant for melanoma circulating tumor ... -
Replication of small ruminant lentiviruses in aluminum hydroxide-induced granulomas in sheep: a potential new factor for viral dissemination
Aluminum (Al)-based salts are widely used adjuvants in ruminants and other species to strengthen the immune response elicited against vaccine antigen(s). However, they can lead to the formation of long-lasting granulomas ... -
Room temperature huge magnetocaloric properties in low hysteresis ordered Cu-doped Ni-Mn-In-Co alloys
(Elsevier, 2022) Artículo / ArtikuluaThe reduction of the thermal hysteresis in first order magnetostructural transition is a determining factor to decrease energy losses and to improve the efficiency of magnetocaloric cooling based systems. In this work, a ... -
Routes for enhanced magnetism in Ni-Mn-In metamagnetic shape memory alloys
The authors provide in-depth physical insight into the enhancement of the magnetic properties of metamagnetic shape memory alloys produced by thermal treatment and cobalt doping. They use neutron scattering to study the ... -
Saline slag waste as an aluminum source for the synthesis of Zn–Al–Fe–Ti layered double-hydroxides as catalysts for the photodegradation of emerging contaminants
In this work, aluminum extracted from saline slag waste is valorized to create a layered double-hydroxide series containing zinc and various proportions of aluminum/titanium. Materials were synthesized by the co-precipitation ... -
