By definition, wafer is something that is small and thin. When wafer is used as an electronics term, it refers to a small thin circular slice of semiconductor material. Generally, when wafer is mentioned in electronics industry, silica wafers would be the first thing to be thought of. Therefore, now we are going to talk [...]
In science, density is defined as mass per unit volume. When a material has high density, it will have greater mass in smaller volume. This explains why mercury and lead are very heavy materials; both of them have high density.
A very simple analogy to describe density is cotton; with cotton we measure its weight, we [...]
Every day, millions of people visit the beach, building sandcastle with the sand on the beach, but they have over-looked the power and abilities of the sand. Did you know anything about sand or at least its uses?
Being a naturally occurring granular material, sand is consisted of finely divided rock and some mineral particles. The [...]
Silica tablets are desiccants which can absorb water molecules to control humidity. In other words, they are drying agents. Due to their high surface area, more moisture can adsorb on the tablet surface for better drying effect. These tablets are very useful in various applications and packaging to protect against degradation of products like drugs, [...]
Vacuum food packing is a method of storing food by air-tight sealing it for the purpose of ceasing the touch of oxygen on food. The vacuumed environment removes atmospheric oxygen, protecting the food from spoiling by limiting the growth of aerobic bacteria or fungi, and preventing the evaporation of volatile components.
Vacuum packing is commonly used [...]
Humidity increases when the weather is getting hot and hotter and eventually speeding the rate of evaporation. Silica gel in general is used to absorb moisture in an enclosed area and can take the relative humidity in a closed container down to about 40 percent. Do you know what damages are likely to occur due [...]
The levels of Silica decline in our body as time passes by. At the time when we are young and cheerful, tissues absorb and maintain a high level of silica and simultaneously our bodies remain flexible, resilient, and energetic with soft supple skin. When we age, our Silica level decreases correspondingly and begin to exhibit [...]
In recent days, the rising greenhouse effects force the globe to suffer greater heat. Besides making an effort to go green, some appliances are invented to give extra comforts to human beings in such torturing weather. Air-conditioning may be good to cool the indoor air however it does no good to the environment at the [...]
