An Innovative MIMO Iterative Learning Control Approach for the Position Control of a Hydraulic Press
(IEEE, 2021-10)
To improve the performance of hydraulic press position control and eliminate the need to manually define control signals, this paper proposes a multi-input-multi-output (MIMO) Iterative Learning Control (ILC) algorithm. ...
A Review of Shared Control for Automated Vehicles: Theory and Applications
(IEEE, 2020-12)
The last decade has shown an increasing interest on advanced driver assistance systems (ADAS) based on shared control, where automation is continuously supporting the driver at the control level with an adaptive authority. ...
Fast correction of errors in the DFT-calculated energies of gaseous nitrogen-containing species
(Wiley, 2021-03-03)
Modeling adsorption phenomena on surfaces by DFT calculations often involves substantial errors, resulting in inaccurate predictions of catalytic activities. Such errors partly stem from the inaccurate description of the ...
Pottery making tradition in Logroño: an archaeometric approach to the Late Medieval workshops
(Springer, 2021-04-23)
This paper deals with the findings of Hospital Viejo site of Logroño (La Rioja, Spain), which yielded the largest evidence of local pottery production, comprising three kilns and a potters’ dump (13th–15th centuries). The ...
Microwave-assisted Palladium catalysed C-H acylation with aldehydes. Synthesis and diversification of 3-acylthiophenes
(Royal Society of Chemistry, 2021-12-22)
The use of MW allows the efficient palladium(II)-catalysed C-3 acylation of thiophenes with aldehydes via C(sp2)-H activation for the synthesis of (cyclo)alkyl/aryl thienyl ketones (43 examples). Compared to standard thermal ...
Palladium-catalysed Heck-type alkenylation reactions in the synthesis of quinolines. Mechanistic insights and recent applications
(Royal Society of Chemistry, 2020-05-18)
Quinoline and quinolone cores are present in a wide variety of pharmaceuticals, agrochemicals and materials, as well in ligands/catalysts in asymmetric synthesis. Transition-metal catalysed based approaches have played a ...
Selective Pd(II)-catalyzed Acylation of Pyrrole with Aldehydes. Application to the Synthesis of Celastramycin analogues and Tolmetin
(Wiley-VCH, 2020-04-27)
The Pd(II)-catalyzed C-2 acylation of pyrrole with aldehydes in the presence of TBHP as oxidant has been studied for the synthesis of di(hetero)aryl ketones. The use of 2-pyrimidine as directing group leads to 2-acylpyrroles ...
Exploring the Slow Magnetic Relaxation of a Family of Photoluminescent 3D Lanthanide–Organic Frameworks Based on Dicarboxylate Ligands
(MDPI, 2021-03-16)
A family of metal–organic frameworks with general formula {[Nd2(ant)2((NH2)2-bdc)(DMF)4]·2DMF}n (1) and {[Ln2(ant)2((NH2)2-bdc)(DMF)4]·2DMF·2H2O}n (Ln = Tb (2), Ho (3), and Er (4)) has been obtained from reactions between ...
Designing Single-Molecule Magnets as Drugs with Dual Anti-Inflammatory and Anti-Diabetic Effects
(MDPI, 2020-04-28)
We have designed and synthesized two novel cobalt coordination compounds using bumetanide (bum) and indomethacin (ind) therapeutic agents. The anti-inflammatory effects of cobalt metal complexes with ind and bum were assayed ...
Enantioselective construction of the 8-azabicyclo[3.2.1]octane scaffold: application in the synthesis of tropane alkaloids
(Royal Society of Chemistry, 2021-03-15)
The 8-azabicyclo[3.2.1]octane scaffold is the central core of the family of tropane alkaloids, which display a wide array of interesting biological activities. As a consequence, research directed towards the preparation ...
