Ringkasan Produk

Cellulose microfibril/nanofibril (CMNF) is

reinforcing material for composites is becoming

more and more attractive to researchers in

composites science because its potential

lightweight and high strength. A network of self-

bonding cellulose fibers within network structure

affects by chemical and mechanical treatment.

In this research we describe an approach to

synthesis CMNF from biosources. The width

of CMNF has been estimated. The true lateral

width of native cellulose microfibrils are smaller

than the presently accepted value and are not

yet justified by direct experimental evidence.

The particle sizes and its distribution were then

characterized by using ASVR AND X-100 size

analyzer.

Greenhouse gases such as carbon dioxide

are the major cause of global warming and

climate change. Development of adsorbents

derived from industrial and agriculture wastes

are attractive as they are abundant and cheap.

The objective of this study is to develop a low

cost and high performance of CO2 adsorbent

using alum sludge. The sludge was dried

in an oven and characterized by scanning

electron microscopy (SEM), electron dispersion

x-ray (EDX), Fourier transform infrared (FT-IR)

spectroscopy, thermogravimetric analysis

(TGA), and N2 adsorption-desorption

techniques. Sorption of CO2 was studied

using a self-assembled fixed bed column at

a pressure of 1 bar. The effects of adsorption

temperature, mass of adsorbent, flow rate of

gas and concentration of adsorbate on CO2

adsorption were investigated. The maximum

adsorption capacity of 34.75 mmol- CO2

/g-sorbent was found when the adsorption

of 10 g of alum sludge was conducted using

0.3 v/v % of CO2 at flow rate and adsorption

temperature of 90 ml/min and 303 K,

respectively. The results also revealed that

the alum sludge has a better CO2 adsorption

capacity than that of the adsorbents developed

by previous researchers. The highly correlated

Freundlich isotherm model ascertained the

applicability of carbon dioxide removal by alum

sludge. This study has demonstrated that the

alum sludge produced from a drinking water

plant could be converted into a useful CO2

adsorbent.

In the past decade, crime has been on a rise

in Malaysia and most people cannot protect

themselves because they either do not like or

are not allowed carrying projectile weapons.

To improvise on the situations on crime, we

formed an idea that can overcome the issue

at hand, which is the Gauss Gun. The gauss

gun does not kill the target but only injure the

target because the projectile does not have a

sharp end and does not travel at velocities high

enough to penetrate the human epidermis. The

gauss gun consists of a series of magnet stages

and ball bearings set in a uniform arrangement.

Its function is to launch a projectile at high

velocities. The physical mechanics involved

are velocity, acceleration, conservation of

momentum and energy
