Peculiar self-nucleation behavior of a polybutene-1/ethylene random copolymer
(Wiley, 2021-07-31)
The self-nucleation behavior of a polybutene-1/ethylene random copolymer, P(B1-ran-E), which undergoes a complex crystal-crystal transition behavior, has been studied in detail. Similar to PE random copolymers, this material ...
COP23: Technical profile with relevant political support
(Dyna (Spain), 2018-01-01)
La Conferencia de las Partes de la Con-vención Marco de Naciones Unidas para el Cambio Climático (UNFCCC, por sus siglas en inglés), conocida como la COP 23, se celebró en Bonn (Alemania) entre los días 7 y 18 de noviembre ...
Maternal occupational exposures and fetal growth in a Spanish birth cohort
(Public Library Science, 2022-04-07)
While the epidemiologic literature suggests certain maternal occupational exposures may be associated with reduced measures of size at birth, the occupational literature employing fetal biometry data to assess fetal growth ...
Thermodynamics of Resonant Scalars in AdS/CFT and implications for QCD
(E. D. P Sciences, 2016)
We explore the thermodynamics of a simple 5D Einstein-dilaton gravity model with a massive scalar field, with asymptotically AdS behavior in the UV. The holographic renormalization is addressed in details, and analytical ...
Maternal circulating Vitamin D-3 levels during pregnancy and behaviour across childhood
(Nature Publishing Group, 2019-10-15)
Vitamin D deficiency during critical periods of development could lead to persistent brain alterations. We aimed to assess the association between maternal vitamin D-3, the major circulatory form of vitamin D, at pregnancy ...
ROP and crystallization behaviour of partially renewable triblock aromaticaliphatic copolymers derived from L-lactide
(Elsevier, 2019-10-26)
Two series of partially biobased ABA triblock copolyesters were successfully prepared by ring-opening polymerization (ROP) of L-lactide initiated by two telechelic polyester polyols using an organic catalyst. B blocks were ...
Theory-guided enhancement of CO2 reduction to ethanol on Ag-Cu tandem catalysts via particle-size effects
(ACS, 2021-10-18)
In the CO2 reduction reaction, the design of electrocatalysts that selectively promote alcohols over hydrocarbons (e.g., ethanol over ethylene) hinges on the understanding of the pathways and specific sites that forms ...
Elucidating the Facet-dependent Selectivity for CO2 Electroreduction to Ethanol of Cu-Ag Tandem Catalysts
(ACS, 2021-04-07)
Despite being desirable high-value products of the electrochemical CO2 reduction reaction (CO2RR), alcohols are still obtained with lower selectivity compared to hydrocarbons and the reaction pathways leading to their ...
Monitoring Active Sites for Hydrogen Evolution Reaction at Model Carbon Surfaces
(RSC, 2021-03-25)
Carbon is ubiquitous as an electrode material in electrochemical energy conversion devices. If used as support material, the evolution of H2 is undesired on carbon. However, recently carbon-based materials are of high ...
Quantum structural fluxion in superconducting lanthanum polyhydride
(Nature Communications, 2023-03-25)
The discovery of 250-kelvin superconducting lanthanum polyhydride under high pressure marked a significant advance toward the realization of a room‐temperature superconductor. X-ray diffraction (XRD) studies reveal a ...
