Comparison of the catalytic activity of MOFs and zeolites in Knoevenagel condensation

Opanasenko, Maksym; Dhakshinamoorthy, Amarajothi; Shamzhy, Mariya; Nachtigall, Petr; Horacek, Michal; García Gómez, Hermenegildo; Cejka, Jiri (Royal Society of Chemistry, 2013)

[EN] The catalytic behavior of metal-organic-frameworks (MOFs) CuBTC and FeBTC was investigated in Knoevenagel condensation of cyclohexane carbaldehyde and benzaldehyde with active methylene compounds and compared with ...
From MOFs to zeolites: zirconium for epoxide rearrangement

Corma Canós, Avelino; Orozco Arboleda, Lina Marcela; Renz, Michael (Royal Society of Chemistry, 2013)

[EN] Zirconium Lewis acid sites grafted onto a mesoporous silicate (MCM-41) and zirconium sites incorporated into inorganic-organic MOF materials are employed successfully in the rearrangement of beta-pinene epoxide into ...
Hydrothermal Degradation Behavior of Y-TZP Ceramics Sintered by Nonconventional Microwave Technology

PRESENDA-BARRERA, ALVARO; Salvador Moya, Mª Dolores; Moreno, Rodrigo; Borrell Tomás, María Amparo (Wiley, 2015-12)

Different factors such as the characteristics of starting powders, their processing, the sintering technique and the final sintering temperature were assessed with the goal to improve the low-temperature degradation (LTD) ...
Metal-containing zeolites as efficient catalyst for the transformation of highly valuable chiral biomass-derived products

Paris Carrizo, Cecilia Gertrudis; Moliner Marin, Manuel; Corma Canós, Avelino (Royal Society of Chemistry, 2013)

Metal-containing zeolites, especially Sn-Beta, perform as very efficient heterogeneous catalysts in the selective oxidation of levoglucosenone, which is considered as a platform chemical for the production of highly-valuable ...
Microsecond transient absorption spectra of suspended semiconducting metal oxide nanoparticles

Baldovi, Herme G.; Ferrer Ribera, Rosa Belén; Alvaro Rodríguez, Maria Mercedes; García Gómez, Hermenegildo (American Chemical Society, 2014-05-01)

The time-resolved absorption spectra of opaque semiconductor powders have been typically studied by diffuse reflectance techniques. Herein, we show that time-resolved transmission spectroscopy of suspended nanoparticles ...
MOFs as multifunctional catalysts: One-pot synthesis of menthol from citronellal over a bifunctional MIL-101 catalyst

García Cirujano, Francisco; Llabrés i Xamena, Francesc Xavier; Corma Canós, Avelino (Royal Society of Chemistry, 2012)

A bifunctional MOF catalyst containing coordinatively unsaturated Cr3+ sites and palladium nanoparticles (Pd@MIL-101) has been used for the cyclization of citronellal to isopulegol and for the one-pot tandem isomerizatio ...
Numerical modelling of pipelines with air pockets and air valves

Fuertes Miquel, Vicente Samuel; López Jiménez, Petra Amparo; Martínez-Solano, F. Javier; López-Patiño, Gonzalo (NRC Research Press (Canadian Science Publishing), 2016-12)

[EN] This work considers the behaviour of air inside pipes when the air is expelled through air valves. Generally, the air shows isothermal behaviour. Nevertheless, when the transient is very fast, it shows adiabatic ...
Photochemical and photophysical properties of dibenzoylmethane derivatives within protein

Marín Melchor, Mireia; Lhiaubet, Virginie Lyria; PARIS, CECILIA GERTRUDIS; Yamaji, Minoru; Miranda Alonso, Miguel Ángel (Royal Society of Chemistry, 2011)

In the present work, three dibenzoylmethane derivatives in their beta-diketo form have been selected to investigate their photophysical and photochemical behavior upon interaction with human serum albumin (HSA). In organic ...
