The noxious gas sensors were developed successfully using flame-spray-made SnO2 nanoparticles as the sensing materials. The functionalized nanoparticle properties were further analyzed by XRD, BET and TEM analyses. The SnO2 nanoparticles (SSABET: 141.6 m2... see more

Three guns based on different thermal spray technologies—namely, gas flame spray, wire arc spray, and wire plasma spray—were operated at each best cost–performance condition, and the resulting spray droplets and deposited coating qualities were investigat... see more

TiO2 is used extensively as a gas sensing material due to its change in electrical conductivity under analyst gas exposure. Gold (Au) is a good catalyst that promotes chemical reactions by reducing the activation energy between sensing film and particular... see more

Combustion-assisted flame spraying (“CAFSY”) has been used to produce catalytically active nickel aluminide coatings on ceramic substrates. Their catalytic activity was studied in CO2 (dry) reforming of methane, which is particularly significant for envir... see more

Piston yang bergerak bolak-balik mengakibatkan keausan pada dinding cylinder liner bagian dalam, hal ini akan menimbulkan penambahan kelonggaran antara torak dan silinder, sehingga dapat menyebabkan kebocoran gas, tekanan kompresi berkurang dan tenaga yan... see more

Technological developments in diesel engines require improvements to the fuel injection system to meet the criteria for economical, high-power and efficient combustion and meet environmental regulatory standards. One method that has a lot of interest is c... see more

Nosel roket merupakan bagian roket yang mengatur laju, masa, arah dan tekanan fluida yang keluar dari ruang bakar. Nosel harus dapat menahan energi kinetik dan panas dari  fluida yang berasal dari ruang bakar.Material yang digunakan pada penelitian i... see more

While a premixed flame front would consume an unburnt matter with a constant speed SL, such a flame occurs extremely seldom in the reality, where flames are curved and characterized by another velocity, Sw, and it is oftentimes conventionally assumed that... see more

Tin oxide-based thin films are deposited by ultrasonic spray pyrolysis technology, in which Cu addition is introduced to enhance the gas sensing performance by H2S detection. The thin films are porous and comprise nano-sized crystallites. One of the Cu-co... see more
