This study replicates the research conducted by Pérez-Paredes, Ordoñana Guillamón and Aguado Jiménez (2018) on language teachers’ perceptions on the use of OER language processing technologies in mobile-assisted language learning. It expands the initial research study by adding Polish, Portuguese, and Turkish educational contexts, surveying 239 English as a foreign language teachers in these three countries. The main findings indicate that there are several differences among the three countries, including institutional support regarding the use of mobile devices and the training provided to the teachers. Based on the data collected in these countries, it was found that mobile devices are mainly used for teaching and learning on online platforms. Smartphones were one of the most used devices in English language teaching, while computer labs at schools seem to have lost their popularity. Regarding the technologies available, the results of the study reveal that the participants are most familiar with online dictionaries, spell checkers, and online collocation dictionaries, and the participants’ qualifications are linked to certain differences in familiarity and use of technologies in the classroom. Variables such as gender, age, and years of experience do not show any difference in the familiarity or frequency of use of those technologies. The main findings of the study point out the importance of institutional support and training regarding the use of mobile devices and open educational resources, which are no longer a choice but a necessity in education.

Recent trends in the area of catalytic applications of metal–organic framework (MOF)-derived nanocarbons are covered. These highly porous nanostructures, convenient for the green chemistry processes, are generally formed by the direct carbonization of a variety of MOF, mainly MOF-5, ZIF-8, ZIF-67, UiO-66-NH2, MIL-101-NH2 at 700–1000 °C in argon or nitrogen flow. Differences between conventional porous carbons and MOF-derived carbons are in pore volumes, surface area, and presence of ad-atoms. The morphology of the MOF-derived nanocarbons can be adjustable with uniform dopant distribution. Resulting nanocarbons are widely applied in heterogeneous catalysis, photocatalysis and are very promising as electrocatalysts, having excellent performance in oxygen evolution reaction, oxygen reduction reaction, and hydrogen evolution reaction. Catalytic applications for environmental purposes are also discussed. Good catalytic performance is related with highly dispersed heteroatoms, density of catalytic active sites, controllable porosity, and high surface area. Opportunities for further research are indicated, in particular, the creation of low pH-stable electrocatalysts and novel strategies for the preparation of 1÷3D single-atom catalysts.
