Abstract Wood is commonly used in construction, but often perceived as being less safe than structures made from non-combustible materials. With the advancement of wood products and treatment, construction techniques, protective systems, this may not be case any longer. Using retrospective data fire departments across Canada, study aimed to determine whether type material (combustible or non-co...

MQ-6 Semiconductor Sensor for Combustible Gas detection is a Sensitive sensor. The sensitive material of this gas sensor SnO2, which works with lower conductivity in clean air. When the target combustible exist, sensors higher along concentration rising. As increases current circuit results resistance. This change used to correspond, output signal concentration. has high sensitivity Methane, Pr...

Reactive materials, such as thermite-like metal-metal oxide mixtures, intermetallic mixtures and combustible metals are being studied as candidates for binary energetic materials. During the past decade, there are several studies to use these reactive materials to design dual functional structuralenergetic materials. Most of the earlier studies resulted in low strength, low density structural e...

Carbonization is a kind of pyrolysis process to produce char from organic materials under an inert atmosphere. In this work, chars derived from various solid wastes were characterized from the standpoint of fuel recovery and pretreatment of waste before landfilling. Sixteen kinds of municipal and industrial solid wastes such as residential combustible wastes, non-combustible wastes, bulky waste...

The increased use of terrestrial crops for biofuel production and the associated environmental, social and ethical issues have led to a search for alternative biomass materials. Terrestrial crops offer excellent biogas recovery, but compete directly with food production, requiring farmland, fresh water and fertilizers. Using marine macroalgae for the production of biogas circumvents these probl...

Recent and future explorations of Mars and lunar surfaces through rovers and landers have spawned great interest in developing an instrument that can perform in-situ analysis of minerals on planetary surfaces. Several research groups have anticipated that for such analysis, Raman spectroscopy is the best suited technique because it can unambiguously provide the composition and structure of a ma...

Mixtures of single-base propellant with chlorine and bromine-containing polymers in different ratios, applied in mines and quarries abroad, were investigated. The exoeffects: maximum temperature of the peak, quantity of released heat and loss of mass were determined by a differential scanning calorimetry, after a standard aging of 120 and 240 hours under conditions imitating the sunshine. Combu...
