New “FACE” of world of chemicals

Worldofchemicals new Design

Hello Good Morning Everyone

We are very happy to announce Today we have launched,

New “FACE” of worldofchemicals.com

With bliss, we bring in our new “FACE,” of worldofchemicals.com As pioneers in chemistry we connect the world chemically, we continue to do so in a best way possible.

The new “FACE” is more user-friendly and well optimized for smart phones and tablets. The new “FACE” comes with a very efficient search, providing information with just a click.

The other features still remain the same – chemicals, academics, media, library, equipments, services, jobs, articles and TWIRL. We need your ever-lasting support. Your support will encourage us for providing a wide array of chemistry information.

Continue learning chemistry with us…

Energy storage, DNA pyramid, killing antibiotic bacteria, killing cancer cells

Study of mechanics of photosynthesis promises efficient energy storage system

Biophysics researchers at the University of Michigan have used short pulses of light to peer into the mechanics of photosynthesis and illuminate the role that molecule vibrations play in the energy conversion process that powers life on our planet… Read more

 

Tiny DNA pyramids kill bacteria more efficiently

Bacterial infections usually announce themselves with pain and fever but often can be defeated with antibiotics – and then there are those that are sneaky and hard to beat. Now, scientists have built a new weapon against such pathogens in the form of tiny DNA pyramids that can flag bacteria and kill more of them than medicine alone… Read more

 

New method to kill antibiotic resistant bacteria

The infection causing bacteria have mechanisms that resist drugs, just like our bodies resist bacteria. This is the reason why doctors increase the dosage of medicine each for the same infection. A research team from Bangalore, India have developed a novel way to attack these bacteria, which gives the organisms little chance of developing resistance… Read more

 

New formulation of chemotherapy drug to kill cancer cells effectively

University of Georgia researchers have developed a new formulation of cisplatin, a common chemotherapy drug that significantly increases the drug’s ability to target and destroy cancerous cells. It is an effective drug, but many cancerous cells develop resistance to the treatment… Read more

10 Resaons why you need more Magnesium

 

Magnesium is important for more than 300 chemical reactions in the human body. The standard American diet is very low in magnesium and high in refined carbohydrates which will increase the need for this vital mineral. If you have sugar cravings, are stressed out and or have low energy there is a good chance you need more magnesium. The body can not make magnesium so it it vital to supply it everyday in adequate amounts. Read complete story here

Artificial enzyme imitates the natural mechanism of liver cells

Scientists at Johannes Gutenberg University Mainz have discovered that molybdenum trioxide nanoparticles oxidize sulfite to sulfate in liver cells in analogy to the enzyme sulfite oxidase… Read more

 

New technique to detect environmental levels of oestrogen

Victoria University of Wellington researchers have developed a new technique that can detect environmental levels of oestrogen at the equivalent of detecting one pinch of salt in an olympic-sized swimming pool… Read more

 

Squid’s teeth may find use in reconstructive surgery

Tentacles of squid are loaded with hundreds of suction cups, or suckers, and each sucker has a ring of razor-sharp “teeth.” The protein present in the teeth will some day form the basis for a new generation of material for reconstructive surgery… Read more

 

19,000 protein producing genes in humans, finds new study

In a new research, scientists have found the number of protein generating genes in humans to be 19,000 – 1,700 fewer than the most recent annotation and well below the initial estimations of 100,000 genes… Read more

 

New laser technology to identify chemical hazards

A portable laser device is being developed at Heriot-Watt that can instantly identify chemical hazards, increasing the safety of emergency services and military personnel… Read more

 

 

 

 

 

Sodium Benzoate Dangers

There’s a great deal of buzz on the internet about sodium benzoate dangers. The question is how much of what you read is fact and how much is fiction. The purpose of this post is to give you the facts.

Chemical properties – Scandium symbol, electronic configuration, density

Scandium is a transition metal. It was discovered in 1879 by spectral analysis, of the minerals euxenite and gadolinite from Scandinavia. The main application of scandium by weight is in aluminium-scandium alloys for minor aerospace industry components. Some items of sports equipment, which rely on high performance materials, have been made with scandium-aluminium alloys. It is also used to make high-intensity discharge lamps.

Imaging flow of nanofluids

Nanofluids, fluids containing nanometer-sized particles, do not always behave as our experiences with the macro-world might lead us to expect. Water, for example, seems to flow much faster within carbon nanotubes than classical physics says should be possible. Now, researchers have found a way to directly image nanofluids… Read more

 

Researchers develop magnetically controlled liquid crystals

Chemists at the University of California, Riverside have constructed liquid crystals with optical properties that can be instantly and reversibly controlled by an external magnetic field. The research paves the way for novel display applications relying on the instantaneous and contactless nature of magnetic manipulation… Read more

 

Water cleaning catalyst converts biodiesel waste into useful chemicals

Michael Wong, Chemical Engineer, Rice University found evidences that palladium-gold nanoparticles are excellent catalysts for cleaning polluted water, but even he was surprised at how well the particles converted biodiesel waste into valuable chemicals… Read more

 

New ‘supercooling’ technique to preserve organs for longer

Scientists have developed a new supercooling technique to increase the amount of time human organs could remain viable outside the body. According to researchers, if it succeeds in humans, it would enable a worldwide allocation of donor organs, saving more lives and allow for more time to prepare the patient and ease logistics at the donor hospital site… Read more

 

New material helps faster healing of wounds

As many patients know, treating wounds has become far more sophisticated than sewing stitches and applying gauze, but dressings still have shortcomings. Now scientists are reporting the next step in the evolution of wound treatment with a material that leads to faster healing than existing commercial dressings and prevents potentially harmful bacteria from sticking… Read more
