Zwitterionic ring expansion polymerization of tert-butyl glycidyl ether with B(C6F5)3 towards the generation of cyclic chains
(Wiley, 2024-06)
The synthesis of cyclic polymers via zwitterionic ring expansion polymerization is limited to a few number of monomer and catalyst pairs. Herein we report the synthesis of cyclic poly(tert-butyl glycidyl ether) through the ...
Association between self-perceived body image and body composition between the sexes and different age classes
(Elsevier, 2021-10-13)
Objectives: The aim of this study was to investigate the association between self-perceived body image and
body composition in the sexes and in different age classes.
Methods: The sample consisted of 632 young adults ...
The outstanding capacity of Prasiola antarctica to thrive in contrasting harsh environments relies on the constitutive protection of thylakoids and on morphological plasticity
(Wiley, 2024-06)
The determination of physiological tolerance ranges of photosynthetic species and of the biochemical mechanisms underneath are fundamental to identify target processes and metabolites that will inspire enhanced plant ...
Crystal-to-crystal polymerisation of monosubstituted [PW11O39Cu(H2O)]5− Keggin-type anions
(RSC, 2024-06)
The reaction between neutral bis(picolinate)copper(II) complexes and copper(II)-monosubstituted Keggin-type phosphotungstate anions formed in situ leads to the formation of the hybrid [C(NH2)3]10[{PW11O39Cu(H2O)}2{Cu(pic)2}]·10H2O ...
Raman imaging spectroscopic solutions for microplastics advanced analysis: Insights from Choqueyapu river basin (La Paz, Bolivia)
(Elsevier, 2024-06-17)
Microplastics (MPs) are causing global concern due to their role as vectors of environmental contaminants. Evaluating their impact on environmental compartments, particularly in sediment and freshwaters, remains challenging ...
Artificial Photosynthases: Single-Chain Nanoparticles with Manifold Visible-Light Photocatalytic Activity for Challenging “in Water” Organic Reactions
(ACS, 2024-04)
Photocatalyzed reactions of organic substances in aqueous media are challenging transformations, often because of scarce solubility of substrates and catalyst deactivation. Herein, we report single-chain nanoparticles, ...
Del compromiso al cumplimiento: La reforma de la Directiva 2012/29/UE sobre los derechos, el apoyo y la protección de las víctimas de delito
(Huygens, 2024-01-30)
La Directiva 2012/29/UE del Parlamento Europeo y del Consejo de la Unión Europea (UE), de 25 de octubre de 2012, por la que se establecen normas mínimas sobre los derechos, el apoyo y la protección de las víctimas de ...
Structural effects of oxidation on sugars: glucose as a precursor of gluconolactone and glucuronolactone
(RSC, 2024-05)
Although structural information on sugars is wide, experimental studies on the oxidation products of sugars in the gas phase, free from solvent interactions, have been rarely reported. We present an experimental work on ...
Escepticismo del profesorado de Primaria en formación hacia las pseudociencias: Influencia de las concepciones erróneas en el caso de la homeopatía.
(Universidad de Granada, 2017-09-01)
Es preocupante que en la sociedad actual haya un gran número de personas formadas y creyentes
en las pseudociencias. La educación, en especial la científica, tiene como objetivo formar a
ciudadanos críticos. Este estudio ...
Early childhood preservice teachers’ knowledge of microorganisms and cystitis
(Firtina Academy, 2024-03-31)
Health literacy should be developed from early ages, but students, including preservice teachers, hold misconceptions about micro-organisms. The objective of this study was to analyse the knowledge that a sample of 102 ...
