Enantioselective Addition of Alkynyl Ketones to Nitroolefins Assisted by Bronsted Base/H-Bonding Catalysis
(Wiley, 2019-03-21)
Various sets of enolizable alkynyl ketones (including methyl ynones with α-aryl, α-alkenyl, and α-alkoxy groups) were able to react smoothly with nitroolefins with the assistance of bifunctional Brønsted base/H-bond catalysts ...
α-Hydroxy Ketones as Masked Ester Donors in Brønsted Base-Catalyzed Conjugate Additions to Nitroalkenes
(ChemPubSoc Europe, 2018-02-15)
Crystallization-induced self-assembly of poly(ethylene glycol) side chains in dithiol–yne-based comb polymers: side chain spacing and molecular weight effects
(ACS, 2024-05)
The chain architecture and topology of macromolecules impact their physical properties and final performance, including their crystallization process. In this work, comb polymers constituted by poly(ethylene glycol), PEG, ...
Competition between O–H and S–H intermolecular interactions in conformationally complex systems: The 2-Phenylethanethiol and 2-Phenylethanol dimers
(ACS, 2024-05)
Noncovalent interactions involving sulfur centers play a relevant role in biological and chemical environments. Yet, detailed molecular descriptions are scarce and limited to very simple model systems. Here we explore the ...
Emissions generated by electric vehicles in the 9-500 kHz band: Characterization, propagation, and interaction
(Elsevier, 2024-06)
Electric Vehicle Charging Processes (EVCPs), due to the involved power electronics with high-switching frequencies, generate high-amplitude emissions that could have a negative impact on Power Quality (PQ) and Narrowband ...
Enhanced photosynthesis, transpiration regulation, water use-efficiency and growth in buckwheat outperforms wheat response to high [CO2], high temperature and drought
(Elsevier, 2024-06)
The rising atmospheric [CO2] levels will increase global temperature and drought events, threatening wheat (Triticum aestivum) production. In recent years, buckwheat (Fagopyrum esculentum) has emerged as an alternative ...
La paridad en manos de Vox: un estudio sobre la disminución de diputadas en el Congreso
(Centro de Estudios Políticos y Constitucionales CEPC, 2024-06-26)
La presente investigación tiene como objetivo contribuir al estudio de los factores que causan la infrarrepresentación de las mujeres en los Parlamentos, centrándose en el caso del Congreso de los Diputados español, donde ...
Covid-19arengatik ezarritako konfinamenduaren eragina unibertsitateko LGB ikasleen egoeran eta osasun mentalean
(UEU, 2024-06-26)
Covid-19ak osasun mentalean izan duen eragina oso ezaguna izan arren, ez dago lesbianen, gayen eta bisexualen (LGB) osasunean pandemiak nola eragin dien zehazten duen ikerketarik Espainian. 475 LGB ikaslek parte hartu zuten ...
Ionic Liquid-Laden Zn-MOF-74-Based Solid-State Electrolyte for Sodium Batteries
(MDPI, 2023-12-12)
Sodium batteries are receiving increasing interest as an alternative to reduce dependence on lithium-based systems. Furthermore, the development of solid-state electrolytes will lead to higher-performing and safer devices. ...
Unveiling the electronic origin of lanthanide based Metal Organic Framework with ideal spin filtering capacity
(Nature, 2024)
Recently, a three dimensional metal-organic framework (MOF) based on Dy(III) and the L-tartrate ligand was experimentally shown to exhibit a spin polarization (SP) power of 100% at room temperature. The material’s spin ...
