Summary: This study investigates the efflorescence patterns on sintered copper particle wicks with different particle sizes. It is found that smaller particles lead to earlier and wider spread of efflorescence due to their lower porosity, while larger particles limit efflorescence to certain areas. A scaling analysis explains the observed patterns by considering the nonuniform porosity and permeability induced by particle size, which reduces the advective flux and results in an exclusion distance where efflorescence does not occur.

Summary: Experimental studies on evaporation, crystallization, and heat transfer in a droplet of NaCl/H2O solution have shown that supersaturation and heating of the wall significantly affect the process. Four characteristic modes of evaporation and crystallization are distinguished, with the ratio of the crystallization rate to the evaporation rate being highly variable and regulated by Marangoni convection. The data obtained provide insights for the development of high-temperature crystallization concepts in the presence of intense Marangoni flow.

Summary: Porous capacitive electrodes are used in supercapacitors and capacitive deionization. The equilibrium potential energy of ions in the pores can be obtained from isothermal calorimetric measurements. A model for the time-dependent heat production at any charging or discharging rate is introduced, which depends on the time-dependent electric potential drop across the double layer. The results provide insight into the electrical double layer and a new way to describe and predict the time-dependent generation of heat from porous capacitive electrodes.

Summary: This study investigates the influence of grain orientation and textured surfaces on droplet evaporation and the wettability of graphene coatings. The results show that on a heated textured graphene substrate, a jump in the contact line of the water droplet is observed in the final stage of evaporation, resulting in an abrupt increase in the contact angle by almost two times. Molecular-dynamic modeling reveals that wettability depends on grain orientation and annealing duration.

Summary: The dissociation and combustion behavior of double gas hydrates in a tubular muffle furnace were studied to improve combustion efficiency and reduce gas emissions. The experiments and simulations showed that double gas hydrates have more stable combustion and their dissociation rate increases with temperature. The presence of heavy hydrocarbons in double gas hydrates reduces unburned CH4 emissions, but increases CO2 emissions. Furnace temperature and gas hydrate composition also impact anthropogenic gas emissions.

Summary: This study investigates the non-isothermal decomposition of mixed methane-ethane hydrate in a furnace and develops a mathematical model to describe the dissociation and combustion process. It is found that increasing the furnace temperature enhances the dissociation rate of methane-ethane hydrate. The combustion of methane-ethane hydrate generates lower emissions of nitrogen and carbon oxides compared to high-potential and conventional fuels. The results suggest that the combustion of methane-ethane hydrate can contribute to reducing anthropogenic gas emissions.
