Enantiopure [6]-Azairidahelicene by Dynamic Kinetic Resolution of a Configurationally Labile [4]-Helicene
(Wiley, 2024-06)
A pair of enantiopure [6]-azairidahelicenes incorporating chirality at the metal center and on the helicenic ligand were synthesized by dynamic kinetic resolution (dkr) of a configurationally labile [4]-helicenic ligand ...
Materials and Strategies to Enhance Melt Electrowriting Potential
(Wiley, 2024-06)
Melt electrowriting (MEW) is an emerging additive manufacturing (AM) technology that enables the precise deposition of continuous polymeric microfibers, allowing for the creation of high-resolution constructs. In recent ...
Deadwood density, C stocks and their controlling factors in a beech-silver fir mixed virgin European forest
(Forest Ecology and Management, 2023-07-01)
Deadwood is a fundamental structural and functional component of forests, with a crucial role in supporting forest biodiversity, nutrient and carbon cycling. Precise deadwood density estimates and its relation to environmental ...
Cognitive reserve counteracts typical neural activity changes related to ageing
(ELSEVIER, 2023)
Studies have shown that older adults with high Cognitive Reserve (HCR) exhibit better executive functioning than their low CR (LCR) counterparts. However, the neural processes linked to those differences are unclear. This ...
Pupillometry reveals differences in cognitive demands of listening to face mask-attenuated speech
(ASA, 2023)
Face masks offer essential protection but also interfere with speech communication. Here, audio-only sentences spoken through four types of masks were presented in noise to young adult listeners. Pupil dilation (an index ...
Cholesterol Constrains the Antigenic Configuration of the Membrane-Proximal Neutralizing HIV-1 Epitope
(ACS, 2020-06-25)
The envelope glycoprotein (Env) enables HIV-1 cell entry through fusion of host-cell and viral membranes induced by the transmembrane subunit gp41. Antibodies targeting the C-terminal sequence of the membrane-proximal ...
Neologismos en la ciencia política. Analizando el concepto de partido desafiante.
(Asociación Vasca de Sociología y Ciencia Política, 2024-07-05)
Los partidos son actores políticos complejos y cambiantes que han ido adaptando sus estructuras organizativas y sus estrategias en función del contexto en el que operan. Debido a la necesidad de comprender la evolución de ...
Searching Materials Space for Hydride Superconductors at Ambient Pressure
(Wiley, 2024-06-19)
A machine-learning-assisted approach is employed to search for superconducting hydrides under ambient pressure within an extensive dataset comprising over 150 000 compounds. The investigation yields ≈50 systems with ...
The P. aeruginosa effector Tse5 forms membrane pores disrupting the membrane potential of intoxicated bacteria
(Nature, 2022)
The type VI secretion system (T6SS) of Pseudomonas aeruginosa injects effector proteins into neighbouring competitors and host cells, providing a fitness advantage that allows this opportunistic nosocomial pathogen to ...
Optimal design and operation of distributed electrical generation for Italian positive energy districts with biomass district heating
(Elsevier, 2022-07-06)
[EN] The active participation of prosumers within the energy generation and distribution stages has revolutionized the energy market favoring the rise of decentralized energy supply configurations and representing a key ...
