Summary: This article aims to understand the Brazilian authoritarian legacy and its connection to recent cases of censorship in the arts and cultural production. The research conducted a survey of cultural productions that were censored or attacked by conservative groups in Brazil from June 2017 to March 2020. The analysis focused on cases that met three criteria: being targeted by conservative action or criminalization of art, receiving national media attention, and prompting reactions or mobilizations in defense of art and freedom of speech. The article argues that the current democratic crisis in Brazil has emboldened authoritarian movements, leading to several episodes of censorship. The study utilizes the concepts of authoritarianism, censorship, and freedom of expression, combined with content analysis, to develop this argument.

Summary: The article introduces a comoving camera system CoMo, consisting of two synchronized cameras and rotational stages, which allows for dynamic tracking of target flock motion. The system addresses calibration of external parameters, measures 3D distances, and achieves a relative error of approximately 1% in 3D tests. The novel approach used in the tests is also highlighted as a powerful tool for detecting and fixing calibration inaccuracies.

Summary: Finding efficient bifunctional electrocatalysts for water splitting is crucial for sustainable energy development. In this study, a novel heterostructure electrocatalyst composed of cobalt-molybdenum (CoMo) alloy particles and CoMoP nanosheets was designed and prepared. This electrocatalyst showed outstanding catalytic activity with low overpotentials for both the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER). The assembled electrode achieved high current density at a low battery voltage.

Summary: This study investigates the performance of chemical looping ammonia synthesis (CLAS) materials under traditional thermal heating and microwave heating, and finds that microwave heating outperforms traditional heating for Fe and CoMo materials. The study also generalizes the principles of microwave catalysis and the heating of metallic particles, and examines the deactivation and regeneration of the materials.

Summary: The positive effect of alumina surface graphitization by CVD with ethylene on the activity of CoMo catalysts in hydrodesulfurization has been demonstrated. The simple CVD approach allows selective modification of the surface of commercially available alumina supports with a layer of graphite-like carbon, improving the activity of conventional hydrotreating catalysts. The improved dispersion of supported sulfide component and enhanced promotion of MoS2 by cobalt contribute to the higher hydrodesulfurization activity of CoMoS/C@?-Al2O3 sample.

Summary: An efficient strategy for synthesizing nanostructured composite supports for CoMoS hydrotreating catalysts is proposed. The synthesis involves the growth of multi-walled carbon nanotubes (MWCNTs) on alumina crystallites modified with Fe2Co nanoparticles. By varying the Fe2Co content, the morphology and structural characteristics of the MWCNT@Al2O3 supports can be adjusted. Comprehensive analysis using advanced techniques identifies the optimal content and structural characteristics of MWCNTs that positively impact the morphology of the sulfide component in the composite supports.

Summary: Electrochemical water splitting for hydrogen production is an environmentally friendly and economical method, but the slow oxygen evolution reaction (OER) at the anode hampers the application of electrolysis technology. In this study, a two-dimensional CoMo Layered Double Hydroxide nanosheets were synthesized and deposited on conductive carbon nanotubes, resulting in a low-cost and efficient OER electrocatalyst.

The obtained catalysts showed the 3DP structure with metal oxides attached to the MF framework. The Co2.0Mo/MF catalyst exhibited high thiophene conversion due to its unique 3DP structure with rich meso-/macropores and low average stacking of crystalline MoS2.
