A statistical design of experiments for optimizing the MALDI-TOF-MS sample preparation of polymers. An application in the assessment of the thermo-mechanical degradation mechanisms of poly (ethylene terephthalate)

Badía Valiente, José David; Strömberg, Emma Marie; Ribes Greus, María Desamparados; Karlsson, Sigbritt (ELSEVIER SCIENCE BV, 2011)

[EN] The sample preparation procedure for MALDI-TOF MS of polymers is addressed in this study by the application of a statistical Design of Experiments (DoE). Industrial poly (ethylene terephthalate) (PET) was chosen as ...
Assessing the MALDI-TOF MS sample preparation procedure to analyze the influence of thermo-oxidative ageing and thermo-mechanical degradation on poly (Lactide)

Badia, J.D.; Strömberg, Emma Marie; Ribes Greus, María Desamparados; Karlsson, Sigbritt (Elsevier, 2011)

[EN] Multiple processing by means of successive injection cycles was used to simulate the thermo-mechanical degradation effects on the oligomeric distribution of PLA under mechanical recycling. Likewise, an accelerated ...
Characterization of Ionic Exchange and Macroporous Resins for Their Application on the Separation and Recovery of Chlorogenic Acid from the Wastewater of Artichoke Blanching

Rodríguez López, Antonio Diego; Reig Riera, Mª Milagro; Mayor, Luis; Ortiz-Climent, Mireia; Garcia-Castello, Esperanza M. (MDPI AG, 2021-08)

[EN] Food wastes have traditionally been considered as dead-end materials; however, recent international, national, and regional policies strongly promote the use of these wastes as potential resources. This change of ...
Estudio de la modelización mediante redes neuronales de los procesos de adsorción-desorción con resinas aplicados a la recuperación de compuestos fenólicos de aguas residuales de la producción de aceite de oliva

Sánchez Rivas, Raúl (Universitat Politècnica de València, 2023-09-27)

[ES] En este Trabajo Fin de Máster se lleva a cabo el estudio y modelado mediante redes neuronales artificiales de los procesos de adsorción y desorción cuyo fin es recuperar los compuestos fenólicos de las aguas residuales ...
Long-term antifungal activity of volatile essential oil components released from mesoporous silica materials

Janatova, Anezka; Bernardos Bau, Andrea; Smid, Jakub; Frankova, Adela; Lhotka, Miroslav; Kourimská, Lenka; Pulkrabek, Josef; Kloucek, Pavel (Elsevier, 2015-05)

[EN] Antimicrobial volatile substances from plants have become known as a suitable alternative to synthetic pesticides and food preservatives. The study tested the antifungal activity against Aspergillus niger of seven ...
New experimental sublimation energy measurements for some relevant astrophysical ices

Luna Molina, Ramón; Satorre Aznar, Miguel Ángel; Santonja Moltó, Mª del Carmen; Domingo Beltran, Manuel (EDP Sciences, 2014-06)

Context. The knowledge of the sublimation energy of ices allows us to better understand the dynamics between surfaces and atmospheres of different environments of astrophysical interest where ices are present. Aims. ...
Recovery of phenolic compounds from olive oil washing wastewater by adsorption/desorption process

Cifuentes-Cabezas, Magdalena Soledad; Sánchez-Arévalo, Carmen María; Mendoza Roca, José Antonio; Vincent Vela, Maria Cinta; Alvarez Blanco, Silvia (Elsevier, 2022-10-01)

[EN] Agroindustry wastewater represents an opportunity to recover high added value antioxidants such as phenolic compounds. An adsorption/desorption process was investigated to recuperate these compounds using Purolite ...
Separation of biobutanol from synthetic fermentation mixtures using unidirectional small pore pure silica zeolites

Pérez-Botella, Eduardo; Claessens, Benjamin; Valencia Valencia, Susana; Rey Garcia, Fernando; Denayer, Joeri F.M. (Elsevier, 2022-12)

[EN] The adsorptive vapour phase separation of 1-butanol from a synthetic ABE (acetone, 1-butanol, ethanol) mixture has been studied for the first time on a set of unidirectional small pore pure silica zeolites with ITW, ...
Upgraded sublimation energy determination procedure for icy films

Luna Molina, Ramón; Millán Verdú, Carlos; Domingo Beltran, Manuel; Santonja Moltó, Mª del Carmen; Satorre Aznar, Miguel Ángel (Elsevier, 2012-06-20)

A method to determine the sublimation energy of a bulk ice in high vacuum systems, allowing other simultaneous analysis techniques, is presented. Variation in frequency of a quartz crystal microbalance, due to sublimating ...
