Advanced Heterogeneous Catalysts For Size- And Shape-selective Reactions

Metal-organic frameworks (MOFs) are a unique class of porous materials constructed using metal nodes and organic linkers, they exhibit many noticeable features which make them as strong candidates for the incorporation of active phases to enable catalytic applications. In particular, heterogeneous catalysts, which are composed of nanoparticles (NPs) incorporated into MOFs, have attracted significant attention

The Kinetics Of Melting And Recrystallization Using Normal Differential Scanning Calorimeter

The Differential scanning calorimeter (DSC) is a widely applied tool to study the thermal behavior of various materials, including melting and recrystallization. However, it is not an easy task to interpret the DSC results of polymer lamellar crystals since they will melt, recrystallize and remelt during heating. Consequently, the endothermal and exothermal peak are combining

Mechanical Production Of Ice Crystals In Clouds

Above about four kilometers up in the atmosphere, clouds begin to contain both liquid droplets and ice crystals. Because two phases of water coexist, a variety of interesting small-scale processes can occur in the cloud: droplets can coalesce and ice crystals can aggregate or droplets can collide with ice crystals and freeze or ice crystals

Wind Energy Pros And Cons

Wind energy pros and cons can be separated into renewable, low operating cost, and energy independence for wind energy pros compared to intermittent energy, large geographic footprint, and limited geographic implementation for wind energy cons. Combating global warming has been on the many people’s mind for decades. Although this remains a controversial topic for some,

Life Cycle Of A Frog: From Tadpole To Frog

The life cycle of a frog, known as metamorphosis, is the transition of a tadpole to an adult frog. The life cycle starts with an egg, which hatches into a tadpole, the tadpole eventually gains hind and front legs, turns into a froglet as it begins to leave the water, then eventually turning into an adult
