Summary: Developing high-performance air purifiers for removing carcinogenic volatile organic compounds, such as formaldehyde, from indoor air is of great practical interest. A portable air purifier system was designed using honeycomb ceramic filters loaded with diaminopropane-appended activated carbon. The system showed high removal efficiencies against formaldehyde, with the best performance achieved using 30% DAP/AC. However, the removal efficiency decreased with an increase in relative humidity. The clean air delivery rate of the system reached a high value, and isotherm analysis demonstrated the complex adsorption behavior of formaldehyde. The superior adsorption properties of DAP/AC can be attributed to both covalent and non-covalent interactions.

Summary: In this study, a 3D composite catalyst was designed, which used nanosheets manganese oxide (MnO2) encapsulating N-doping graphene sphere (GS), to effectively remove indoor formaldehyde. The catalyst had a larger specific surface area and uniform dispersion, which facilitated exposing more active sites and achieving fast transport kinetics for efficient catalytic reaction, converting formaldehyde into harmless substances. Moreover, through chemical adsorption, formaldehyde could be enriched and rapidly degraded even at low concentrations. This study provides inspiration for the potential application of 3D composite materials in fields such as environmental engineering and energy industry.

Summary: Chitosan, especially from snow crabs, was found to be more effective in HCHO removal compared to chitosan from red crabs, due to the higher amino content in the molecule. The protonation of amino groups was identified as the reason for decreased adsorption capacity at low pH. The optimum pH for purification efficiency was around 6, with a static adsorption efficiency of 89.6% and 34.8% in dynamic conditions.

Summary: Minimal use of noble metals is ideal in developing catalytic systems against carcinogenic formaldehyde (FA) in air. A highly dispersed platinum ensemble on titanium dioxide was synthesized and validated to achieve high conversion of FA. The role of surface lattice oxygen in the overall reaction was supported by the prominence of Mars van Krevelen kinetics. The density functional theory simulation distinguished the roles of different Pt catalysts.

Summary: UV-PCO air filters have low concentrations of typical byproducts for most pollutants, but are not recommended for buildings with high ethanol levels. A new exposure-based evaluation standard was developed based on formaldehyde generation, with 32.5% of cases identified as suitable for residential and commercial HVAC system applications and all cases suitable for industrial buildings. Parameters such as challenging compound types, inlet concentrations, and air velocity were found to be the main factors affecting the applicability of UV-PCO.

Summary: This study compared transformative leadership from previous presidents towards the present president, Joko Widodo, through literature studies and examined the presence of leadership style for each president. During a crisis, transformational leadership is necessarily required to manage the economy, politics, and society in Indonesia. Successful transformative leadership indicators include striving to advance the nation, avoiding prioritizing their group for the sake of national unity and sovereignty, understanding subordinates' problems, motivating them to seek new approaches in performing their duties, listening attentively to subordinates' input, and paying attention to their needs.
