The photocatalytic reaction involved in TiO2 photocatalysis was investigated using a microreactor coated with TiO2 film on the glass plate attached on one side of the microreactor. It was confirmed that the effect of H2O2 on the photocatalytic degradation efficiency of azo dyes (acid orange 7, acid red 151, and acid yellow 23) was dependent on the polymorphs (anatase and rutile) of TiO2 coated on the glass plate of the UV-irradiated microreactor. Scavengers of holes (KI) and electrons (p-benzoquinone) were added to [...]

One-pot synthesis of mesoporous hybrid material consisting of Mn-Co/CoO nanoparticles encapsulated in an N-doped graphene shell decorated with Mo2C nanoparticles (Mo2C-NC@Mn-Co/CoO) was reported. The Mn and Mo components synergistically refined the graphitized carbons due to the interactions with N and C atoms while promoting the stability of the Co/CoO nanoparticles. These components exhibited a beneficial effect on the dispersion of the active metal/metal oxide nanoparticles and the formation of a mesoporous stru [...]

Buildings account for a significant portion of global energy consumption, estimated at 30-40%, and also contribute to greenhouse gas emissions. Energy consumption in a building is mainly thermal (natural gas) and electrical. This energy is usually used for heating water, cooking, illumination, ventilation and air conditioning, powering appliances, floor heating, and other activities. These activities were examined, and their substitution by solar-based energy sources was reviewed. To achieve this objective, an exte [...]

The rising concerns of soil erosion, organic waste generation and global warming have shown the need to address them through multifaceted methods that transcend conventional linear models of resource utilization. Circular economy is a regenerative model that is anchored on caring about waste valorisation, resource effectiveness and environmental fortitude. In this paradigm, biochar has been developed as a multifunctional compound capable of integrating waste management, soil rehabilitation, climate control and rene [...]

The development and utilization of pharmaceuticals, notably antiretrovirals (ARVs), have significantly enhanced both human quality of life and life expectancy. Nevertheless, the excretion of these compounds into aquatic environments, often exacerbated by inadequate sanitation infrastructure, poses considerable risks to biota. This investigation evaluated the environmental impact of 14 ARVs consumed within the municipality of Belo Horizonte (BH), Brazil. The assessment employed the Environmental Risk Assessment (ERA [...]

The rising pollution levels in congested urban areas pose a serious threat to human health. Many solutions have been proposed to control and reduce gas emissions from road traffic, with results that are not entirely satisfactory. The adoption of new techniques and methodologies for early detection of pollutant emissions may enable effective management and control of road traffic contamination. The proposed method introduces an interactive protocol that facilitates communication between the traffic control center an [...]

This study proposes a novel creative tourism model integrating artistic creation with circular economy principles to foster regional revitalization in North Euboea, Greece. Employing a case study approach, it develops the concept of “Cultural Cells”—dedicated hubs for artists and art students specializing in painting and sculpture—designed to enhance tourism through immersive engagement. The methodology combines qualitative analysis of regional cultural and environmental assets with theoretical estimates of circula [...]

The management of healthcare waste (HCW) presents a significant environmental and public health challenge, aggravated by gaps in current Brazilian federal regulations. This study provides a comprehensive analysis of specific state and municipal legislation on HCW, comparing it with ANVISA Resolution No. 222/2018 and CONAMA Resolution No. 358/2005 to ascertain whether local regulations enhance management practices and can act as supplementary instruments to federal guidelines. The methodology was structured into thr [...]
