The COVID-19 pandemic caused drastic changes in education, which had to adapt to changing scenarios (online, face-to-face, hybrid teaching). Within physical education (PE), strategies such as 'do not use or share equipment' were proposed to avoid infections. These strategies fit with an emerging pedagogical model called the Self-made Material Model (SMM), which involves students creating their own PE equipment. The objectives of the present study were: (a) to analyse PE teachers' beliefs about the use of self-made material in their classes, (b) to evaluate teachers' perceptions of the impact of the use of self-made material in PE lessons during the pandemic and (c) to examine gender/age differences. A quantitative, snowball research design was followed. The ( Méndez-Giménez and Fernández-Río, 2011) comprising two scales (41 items) was adapted: scale and scale. In total, 1093 in-service teachers (443 women, 40.5%; = 41.39, SD = 9.54) from 13 Ibero-American countries participated. Descriptive statistics were calculated, Student's test was conducted for comparisons by gender and one-way analysis of variance (ANOVA) was run for comparisons by age ranges. Overall, the scores were high, emphasising the potential to promote recycling and students' creativity and respect for the material. Women scored higher in items such as promoting interdisciplinarity, equality, attention to disability and education in values. In total, 833 (76.21%) teachers used self-made material during the pandemic and reported high levels of satisfaction, expectations of use, usefulness and profitability. No gender differences were found. In the COVID-19 era, the SMM is playing a relevant role as a meaningful framework and a helpful teaching methodology in different educational scenarios.

The purification of polysaccharides is an essential preliminary step in determining their chemical structure, although it presents significant challenges. In this research, a macro-porous monolith of quaternary chitosan cryogel was synthesized for the purification of a neutral polysaccharide from Boletus auripes. A homogeneous neutral polysaccharide (BAP-1a1) with a weight-average molecular weight of 4.

Mesoporous carriers have gained significant attention for enhancing the solubility and bioavailability of Biopharmaceutics Classification System (BCS) Class II drugs. However, the contribution of mesoporous carriers with varying morphologies to the physical stability of these drugs is not well-defined. In this work, mesoporous carbon nanoparticles (MCN) and hollow carbon mesoporous nanoparticles (HMC) were prepared, while the weakly acidic Indomethacin (IMC) and alkaline Celecoxib (CXB) were incorporated into these carriers in the amorphous state by the solvent evaporation method.

In colorimetric analysis, nanozymes are invaluable tools due to their simple production, long-lasting stability, and adaptable enzymatic activity, which enable them to induce changes in substrate color. In this study, a simple nanozyme-based colorimetric sensor was developed to detect cannabidiol (CBD) by using the laccase activity of the self-made MOF with copper and cobalt loading (Cu/Co@MOF) nanozyme, which was synthesized using a one-pot microwave method. The Cu/Co@MOF has the ability to catalyze the coupling reaction between 4-AP and various phenolic substrates, thereby converting colorless phenolic substrates into red substances.

Purpose: The prevention of preterm birth is a challenging task for obstetricians. Cervical cerclage, used as both a primary and secondary prevention method for spontaneous preterm birth, is a crucial surgical intervention. It is essential that obstetricians can learn this procedure in a simulated environment before performing the stitches on high-risk patients.

Zinc ion capacitor (ZIC) is regarded as a new generation of energy storage device because of high redox potential of zinc anode, eco-friendly and safety. Herein, using hemicellulose as precursor and self-made cubic CaCO as template, the porous carbon spherical micron-cage (MCs) were prepared by template method assisted physical activation method. The prepared MCs are mainly rich in mesopores and micropores.
