New surfaces repel most known liquids!! ~ Chemistry&Technology | Chemistry & Technology | Scoop.it

In an advance toward stain-proof, spill-proof clothing, protective garments and other products that shrug off virtually every liquid — from blood and ketchup to concentrated acids — scientists are reporting development of new “superomniphobic” surfaces. Their report on surfaces that display extreme repellency to two families of liquids — Newtonian and non-Newtonian liquids ....

لا تهمل هذه الأطعمة الحمراء فهي مفيدة للصحة!

من المعروف أن اللون الأحمر هو لون الحب، وأن المعدة هي الطريق الأسهل للوصول إلى "القلب"، لذا ينصح الكثير من خبراء التغذية بضرورة تناول الأطعمة الحمراء، وفي هذا التقرير نستعرض خمسة أنواع من هذه الأطعمة وفوائدها على الصحة.

 

تكثر الأطعمة التي تتميز بلونها الأحمر.وسواء أكان اللون الأحمر غامقا أو فاتحا، إلا أن الأطعمة الحمراء تعتبر من الأطعمة المفيدة جدا للصحة، ويعود سبب ذلك إلى أن هذه الأطعمة تكتسب اللون الأحمر من الكميات العالية لمضادات الأكسدة الموجودة فيها. ولتناول هذه الأطعمة أثراً إيجابياً على الصحة، فتناول الفواكه الحمراء يقلل من خطر الإصابة بالسرطان، بينما تقلل الخضروات الحمراء من خطر الإصابة بالسكتة الدماغية.

وفيما يلي نستعرض 5 أطعمة حمراء وفوائدها الصحية:

Fuel cell breakthrough to low-cost nickel-based catalyst ~ Chemistry&Technology | Chemistry & Technology | Scoop.it
Tamer ramzy Abd-Elsadek's insight:

The two most promising current candidates for cars are fuel cells, which convert the chemical energy of hydrogen to electricity, and rechargeable batteries.

The University of Delaware's Yushan Yan believes that fuel cells will eventually win out.

"Both fuel cells and batteries are clean technologies that have their own sets of challenges for commercialization," says Yan, Distinguished Engineering Professor in the Department of Chemical and Biomolecular Engineering.

Tamer ramzy Abd-Elsadek's insight:

For the study, an international team of researchers created a digital audio platform that allowed them to covertly alter the emotional tone of people's voices while they were talking to make them sound happier, more sad or more fearful.

Then, the researchers asked 109 participants to read a short story aloud while listening to themselves through a headset.

Purify mining water in hours, not years!! ~ Chemistry&Technology | Chemistry & Technology | Scoop.it

Cleaning up the water left over from mining operations can literally take generations—25 to 50 years on average—leaving billions of gallons of the precious resource locked up and useless.

Now, researchers have figured out how to trim that time dramatically—to just two to three hours. The advance could be a potential boon to mining companies, the environment, and global regions where water is scarce.

العلوم والتكنولوجيا: ألام الظهر والعمود الفقري وضعف النظر والصداع وتجنبها!! | Chemistry & Technology | Scoop.it
Tamer ramzy Abd-Elsadek's insight:

 

متاعب مهنية يمكن تجنبها

ألم في الظهر وضعف في النظر وصداع..أعراض يعرفها من تتطلب طبيعة عملهم الجلوس طويلا أمام شاشة الكمبيوتر وقد يتطور 

الأمر لأمراض تحتاج لشهور عديدة في علاجها، فهل من طريقة لتجنب الآثار الجانبية لساعات الجلوس الطويلة؟

 
 

آلام الظهر وضعف النظر من المتاعب المرتبطة بالمهن التي تحتاج لساعات جلوس طويلة، وقد تتسبب مع الوقت في إصابات مؤلمة تحتاج لعلاج طويل. الحرص على بعض الأمور أثناء العمل يقي من هذه المخاطر أو على الأقل يخفف من حدتها.

 

 

وتعتبر طريقة الجلوس أمام الكمبيوتر في مكان العمل من أبرز أسباب مشكلات الظهر، وهنا يحذر الخبراء من الاقتراب الشديد أو الابتعاد الشديد عن الشاشة، فالوضع المثالي يتمثل في أن تكون الرأس والجزء العلوي من الجسم على استقامة واحدة وبشكل طبيعي.

 

 

وللحفاظ على النظر، ينصح الخبراء وفقا لصحيفة "برلينر تسايتونغ" الألمانية، بألا تقل المسافة بين العين وشاشة الكمبيوتر عن 50 سنتيمترا، يفضل أن تصل لـ 70 سنتيمترا مع الشاشات الكبيرة في الحجم. ولتجنب الإشعاعات يجب

How Full Moon Could Affect Winter Storm Jonas!!! ~ Chemistry&Technology

How Full Moon Could Affect Winter Storm Jonas!!! ~ Chemistry&Technology | Chemistry & Technology | Scoop.it

A full moon occurs when the Earth, sun and moon form one straight line, with the Earth in between, so that the moon is fully illuminated by the sun. When this happens, the moon's gravitational pull on the Earth's tides increase, because the gravity of the sun reinforces the moon's gravity.

 

 

As a result, during the full moon, the high tides are higher and low tides are lower than at other times in the month. These high tides are known as astronomically high tides and can be about 5.5 feet (1.7 meters) tall, according to Patrick Maloit, a meteorologist at the National Weather Service (NWS) office in New York.

Does it rain on the Sun, what's the Difference? ~ Chemistry&Technology | Chemistry & Technology | Scoop.it
Tamer ramzy Abd-Elsadek's insight:

Sometimes the most familiar things can be the most surprising. So how about this? Our Sun (that big ball of nuclear fire in the sky) has long-lost siblings – and it rains on the Sun.

Right now, our Sun is pretty lonely – over four light years from its nearest neighbour, Alpha Centauri. But its birth wasn't solitary. Like most stars, our Sun condensed from a vast molecular cloud of dust and gas (mostly hydrogen and helium, but with other trace elements). Around 4.6 billionyears

A team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has created a super-strong yet light structural metal with extremely high specific strength and modulus, or stiffness-to-weight ratio. 
 
The new metal is composed of magnesium infused with a dense and even dispersal of ceramic silicon carbide nanoparticles. It could be used to make lighter airplanes, spacecraft, and cars, helping to improve fuel efficiency, as well as in mobile electronics and biomedical devices.

This is believed to be the first study of "random projection," the core component of the researchers' theory, with human subjects.
 
Humans learn to very quickly identify complex objects and variations of them. We generally recognize an "A" no matter what the font, texture or background, for example, or the face of a coworker even if she puts on a hat or changes her hairstyle.
