CASPT2 study of the electronic structure and photochemistry of protonated N-nitrosodimethylamine (NDMA-H+) at 453 nm
In this work, we have studied the photodissociation of the protonated derivatives of N-nitrosodimethylamine [(CH3)2N–NO] with the CASPT2 method. It is found that only one of the four possible protonated species of the ... -
Catalytic performance of bulk and Al₂O₃-supported molybdenum oxide for the production of biodiesel from oil with high free fatty acids content
Non-edible vegetable oils are characterized by high contents of free fatty acids (FFAs) that prevent from using the conventional basic catalysts for the production of biodiesel. In this work, solid acid catalysts are used ... -
Catalytic photodegradation of organic compounds using TiO2/pillared clays synthesized using a nonconventional aluminum source
This study evaluates the photocatalytic degradation of 2,6-dichlorophenol (2,6-DCP), triclosan (TCS) and bisphenol A (BPA) by ultraviolet (UV) and visible (VIS) light in the presence of TiO2/catalysts synthesized by wet ... -
Catalytic valorization of CO2 by hydrogenation: current status and future trends
Terrestrial environmental and biological systems are being threatened by the tremendous amount of human carbon dioxide emissions. Therefore, it is crucial to develop a sustainable energy system based on CO2 as chemical ... -
Catalyzed methods to synthesize pyrimidine and related heterocyclic compounds
This review covers articles published in the period from 2010 to mid-2022 on synthetic advances in the formation of pyrimidine and related heterocyclic compounds. Special emphasis has been given to the different types of ... -
Cellulose polymers with β-amino ester pendant group: design, synthesis, molecular docking and application in adsorption of toxic metals from wastewater
Background: Cellulose polymers with multidentate chelating functionalities that have high eficiency for toxic metal ions present in water were designed, synthesized, and analyzed. The synthesis was carried out by reacting ... -
Characterization of combustion anomalies in a hydrogen-fueled 1.4 L commercial spark-ignition engine by means of in-cylinder pressure, block-engine vibration, and acoustic measurements
Abnormal combustion phenomena are among the main hurdles for the introduction of hydrogen in the transportation sector through the use of internal combustion engines (ICEs). For that reason the challenge is to guarantee ... -
Characterization of two iron bullets from the royal ammunition factory of Eugi (Spain)
In this work, a comparative analysis of two iron bullets found in The Royal Ammunition Factory of Eugi in Navarra (Spain) was performed. Both bullets presented a spherical shape with a relatively good state of preservation, ... -
Checking unimodality using isotonic regression: an application to breast cancer mortality rates
In some diseases it is well-known that a unimodal mortality pattern exists. A clear example in developed countries is breast cancer, where mortality increased sharply until the nineties and then decreased. This clear ... -
Chemical and mechanical stability of air annealed cathodic arc evaporated CrAlON coatings
This study reports the synthesis and characterization of ternary Cr-Al-O and quaternary Cr-Al-O-N coatings deposited by cathodic arc physical vapour deposition, for various nitrogen and oxygen mass flow ratios during the ... -
CIELAB color paths during meat shelf life
Meat color evolution from freshly cut to beyond shelf life, up to 40% of metmyoglobin, has been theoretically modeled using the Kubelka-Munk theory and a set of measured reference reflectance spectra of deoxymyoglobin, ... -
Classical and new insights into the methodology for characterizing adsorbents and metal catalysts by chemical adsorption
The adsorption phenomenon has been used extensively to achieve and explain solid-state reactions, control contamination, and purify liquids and gases. This process implies the use of a porous medium or a material with ... -
Clean syngas production by gasification of lignocellulosic char: state of the art and future prospects
Using lignocellulosic char instead of the original biomass avoids the need for costly cleaning and conditioning stages of the producer gasification gas. However, lignocellulosic char gasification has been less extensively ... -
CO2 methanation over nickel catalysts: support effects investigated through specific activity and operando IR spectroscopy measurement
Renewed interest in CO2 methanation is due to its role within the framework of the Power-to-Methane processes. While the use of nickel-based catalysts for CO2 methanation is well stablished, the support is being subjected ... -
A combination of a vibrational electromagnetic energy harvester and a giant magnetoimpedance (GMI) sensor
An energy harvesting device combined with a giant magnetoimpedance (GMI) sensor is presented to analyze low frequency vibrating systems. An electromagnetic harvester based on magnetic levitation is proposed for the electric ... -
A combination of Rosa canina extracts and gold complex favors apoptosis of Caco-2 cells by increasing oxidative stress and mitochondrial dysfunction
Given the alarming increase in colorectal cancer (CRC) worldwide, novel therapies are urgently needed. Plant-derived extracts have gained considerable interest in the last years due to their strong anticancer effect mediated ... -
