Food Irradiation: Weaponizing meals or making them safe for the masses?

In this post we will discuss what food irradiation actually is and how it can be achieve and described through nuclear chemistry.  This "Xtranormal" video serves as a brief introduction to what food irradiation is and why not to be afraid of it:




Next, this "Prezi" contains all sorts of information about food irradiation, from the decay of cobalt-60 to create gamma rays needed for the process, to the risks and benefits of irradiating food.

Enjoy!!!

Chemical Engineering Is the Future of Technology

Sunday, April 3, 2011

In today's world, it is becoming increasingly necessary for man to be able to manipulate the world around him in order to thrive, and as we continue to thrive we have to learn how to undo the damage we have done in past years. Chemical engineers are the only tool we have for new research and development in almost every field, including the medical field, environmental science, research science, and a large portion of the research done in the technological fields.



Microelectronics involves itself in the development of technology that will aid those in the medical professions. They study plasma processes, which are used in a number of treatments, and laser technology, which enables doctors to perform surgeries faster, more safely, and more affordably that ever before. They also study super-molecular self-assembly and organization and colloidal systems, all for use in the continued study of the human body and how it grows and develops. These technologies are enabling doctors to treat patients quicker and cheaper, which is more than necessary when one considers the dramatic shortage of doctors and nurses and the ever-growing list of people needing medical treatment. These technologies help an entire host of issues; the decrease in cost leads to health insurance becoming more affordable and therefore more accessible to the everyday citizen. Easier recovery times and safer surgeries lead to a higher survival rate and a better standard of living.



Technological development is not the sole focus of chemical engineering, however. Biochemical engineering involves the study of mammalian tissues, virus removal from blood, protein manipulation, and a wide array of genetic engineering technologies. These research scientists are leading the way to a number of cures and treatments that will improve the health of America Imagine a day when HIV/AIDS, cancers, and a wide array of terminal and debilitating conditions have been eradicated or are easily treated.



The focus of chemical engineering spans more than just the medical field, however. Almost all students majoring in chemical engineering study the use of resources like oil and natural gas and can delve into research for more efficient methods of obtaining these fuels and exercising them to their full potential. In today's world, with gas prices fluctuating and the populous dissatisfied, no profession could be in higher demand.



The U.S. Military, as well, is interested in chemical engineers that specialize in polymer engineering, which is the study of the synthesis of different chemicals, and process engineering, the study of catalyst development and fault detection and control, as they can work with the military to develop weapons.



Chemical Engineers are closer than ever to finding cures for deadly diseases, defending our nation from hostile countries, and improving the standard of living for citizens. Those that invest their time and money in a chemical engineering program will not be disappointed, as there is an endless spectrum of meaningful, important careers, opportunities, and chances to shine.

Masters and Ph.D Students Wanted

Wednesday, March 23, 2011

Do you have intention to further study in Chemical Engineering? If you have a chemical engineering degree and would like to pursue your masters or Ph.D degree, now is your chance. My wife, Dr. Mazura Jusoh from Faculty of Chemical Engineering, Universiti Teknologi Malaysia, is searching for a few post graduate students and this is an opportunity for those who are interested.


The field is obviously Chemical Engineering which will focus on Separation Technology. To be more specific, you will explore the fundamental and science of Progressive Freeze Concentration, a field which is still not explored in Malaysia.

Financial assistance will be provided for the first few students only. So, to grab hold of this offer, you need to act fast.

Masters duration - Full time research - 2 years.
Ph.D duration - 3 years.

Interested candidate can write and send your CV to the following email address:

mazura[alias]cheme.utm.my.

Here is an example of a related study of this field...

Abstract : DEVELOPMENT OF A NOVEL DESIGN FOR PROGRESSIVE FREEZE CONCENTRATION PROCESS

Industrial wastewater may well be treated by freeze concentration, a process which freezes or crystallises out water content as pure ice crystals and leaves behind a highly concentrated solution in a smaller volume. In conventional suspension freeze concentration (SFC) whereice crystals formed as a suspension in the mother liquor, separation of the solid-liquid mixture is difficult and costly. The size of ice crystals is still very limited and the seeding process requires usage of scraped surface heat exchangers (SSFE), which is significantly expensive and accounted for approximately 30% of the capital cost. Progressive freeze concentration (PFC) invented later is believed to provide cost saving and simplify the subsequent ice-liquid separation as ice crystals are formed as a layer or a block on the cooling surface. Quest for a design providing convenience and good efficiencies continues, and in this study a helical structured copper crystalliser was developed and fabricated named Multi-wind Crystalliser (MWC). Effects of several operating conditions on the performance of MWC in context of wastewater treatment were then investigated including circulation flowrate, initial solution concentration, coolant temperature and circulation time. The performance of the design was evaluated by three dependent variables including the effective partition constant, K, calculated from the volume and concentration of the solid and liquid phase. Two other parameters were ice purity and solution volume reduction. A process optimisation was also performed thereafter employing STATISTICA to produce optimum conditions in favour of the stated independent variables. As the crystalliser designed involves heat transfer, the overall heat transfer coefficient was also calculated through temperature profiling subsequently generating a prediction model for ice crystal mass. At the end of the research, a new crystalliser design for PFC is established and an observation of how the operating conditions affect the performance of the system was obtained. Optimum operating conditions was determined by process optimisation and an overallheat transfer coefficients were also generated. Adequacy and reliability of the ice crystal mass prediction model produced was proven by error analyses revealing relatively small errors.

How about some "Creative Chemistry"?....Anyone?...

Saturday, February 5, 2011

So how about short "artsy" post to stimulate the mind? Maybe a Haiku and a cool slide show? What do you think?

Well, if I could actually hear your responses, I would hope that the answer would be, "Yes! Go for it!" So without further ado:

Here is a Haiku about why and how atoms form covalent bonds by sharing electrons:


Photobucket

Because the electron configurations of noble gasses (8 valence electrons and completely full outer shells) are the most stable of all configurations, when forming compounds, atoms strive to gain an octet.  Thus, they will share the number of electrons needed for all atoms to have eight electrons in their highest energy level shells.


The image to the left shows how two Group 17 (7A) elements (two atoms with 7 valence electrons) can combine to create one single bond and a diatomic molecule.

Now, here is a short Animoto (an juiced up slide show) about five or six of the simplest molecular geometries and some household items that resemble these shapes.  Enjoy!!
