Google Nexus 10 vs. Apple iPad (4th generation ... - Know Your Cell

The much-anticipated Google Nexus 10 has finally arrived and it's looking pretty sweet. With such an awesome screen and Android 4.2 Jelly Bean, the tablet looks nearly perfect. Besides some nice specs, what else does Google's tablet have to offer? Is it able to match Apple's new 4th generation iPad?

To answer these questions fully, we?re comparing the Google Nexus 10 with the new iPad below. Read on to find out who wins!

Design

The design found on the Nexus 10 and iPad is quite different, but let's start with the iPad. The iPad is very thin and extremely light. It is really all display in a single aluminum unibody and not much bezel. The iPad looks and feels sexy.

The Google Nexus 10, meanwhile, features a more clunky design in comparison. It has a considerable amount of bezel and a light, black unibody frame. It feels very light in the hand, yet durable.

Winner -- Apple iPad! Both devices have amazing designs, but the aluminum unibody of the iPad is much more attractive. It's also a design consumers recognize instantly.

Specs

As mentioned in previous posts, Apple?s 4th generation iPad runs on an A6x quad-core Cortex-A15 processor. This CPU is a real beast and offers an amazing GPU for great gaming. It also makes the iPad extremely smooth. The iPad also comes in three flavors: 16GB, 32GB and 64GB, but offers no support for removable memory.

The Google Nexus 10, on the other hand, is powered by an equally powerful Exynos 5 CPU. The 5 series of Exynos processors are usually reserved for Apple products, so it's interesting to see it show up in the Nexus 10. In comparison to the A6x, it's pretty equal.

Like the 4th gen iPad, the Google Nexus also features 16GB and 32GB storage variants, though a 64GB version is not there. The Nexus 10 also doesn't have any removable memory support.

Winner -- Draw! The A6x and the Exynos 5 are equally matched.

Screen

The iPad features a 9.7-inch retina display that operates at a pixel density of 326PPI. From my own tests, the display offers great color reproduction and images look extremely crisp and clear. All in all, the display on the iPad is great.

In comparison, the Google Nexus 10 sports a dazzling 2560 x 1600 high resolution display. HD movies are more vivid and photos will look as clear as the day you took them on the device. Does the Nexus 10 screen match the iPad's display? Absolutely.

Winner -- Draw!

Software

Apple's iPad is powered by iOS 6, and while the operating system is still the most polished in the land, it is a bit one dimensional and a little boring. It is extremely easy to use though, so it definitely has that going for it.

The Google Nexus 10 features Android 4.2, Google's all new mobile OS. The new OS is similar to Jelly Bean, offering just a few more tweaks, including a new Google Now app and home screen UI. It is equal to, if not better than iOS 6.

So who wins in terms of software? Apple, of course, as it holds the app store advantage. The company has hundreds of thousands of iPad apps in its store, whereas the Nexus 10 probably doesn't even have 5,000. Apple always wins when it comes to apps.

Winner -- Apple iPad.

And the overall winner is...

4th generation Apple iPad.

The devices are, in most areas, evenly matched, but the design and OS on the iPad is just better. The Google Nexus 10 is a big step in the right direction for Google, but it has a little more improvement to go, especially with regards to apps.

Maybe next year, Google.

Get rid of bodyweight. Obesity, or maybe carrying around only a few extra pounds, will surely have numerous adverse health and fitness effects. Certainly one of these consequences is undoubtedly an greater inclination to snore. The more substantial you might be, the greater most likely your airway should be to develop into restricted by surplus fat and flesh. Drop the lbs . to alleviate the challenge.

One of several best strategies to halt Enter via this link is to cease alcoholic beverages use. Any time you take in alcohol, the muscle mass from the again of your throat become too calm. This condition of relation can boost your likelihood of snoring. In case you really need to consume, only have a couple of.

Should you have been accused of snoring and keeping your associate awake in the evening, resist the impulse to state "I tend not to snore", like most people do. Possibilities are, if an individual states you need to do, it is true. Try out as an alternative to empathize using your liked a single and offer you to view a doctor to rule out slumber apnea or another diseases.

The hunt for electron holes: A molecular glance on solar water splitting

ScienceDaily (Oct. 30, 2012) ? Hydrogen production by solar water splitting in photoelectrochemical cells (PEC) has long been considered the holy grail of sustainable energy research. Iron oxide is a promising electrode material. An international team of researchers led by Empa, the Swiss Federal Laboratories for Materials Science and Technology, have now gained in-depth insights into the electronic structure of an iron oxide electrode -- while it was in operation. This opens up new possibilities for an affordable hydrogen production from solar energy.

Hematite, the mineral form of iron oxide (or trivially, rust), is a promising anode material for photoelectro-chemical cells (PEC) because of its affordability, availability, high stability and good spectral match to the solar spectrum. Although it has the potential of a 15% solar-to-hydrogen energy conversion efficiency, its actual efficiency is lower than that of other metal oxides. This is due to hematite's electronic structure, which only allows for ultrashort electron-hole excited-state lifetimes.

Helpful holes in hematite

Electrons are well-known (negative) charge carriers, indispensable in our daily lives, but they do not play this role alone. When an electron leaves its assigned place, it leaves behind a hole that can effectively behave like a positive charge carrier, provided that the electron and hole remain separated and do not recombine. In modern semiconductor electronics, holes are important charge carriers, without which devices like batteries, capacitors, fuel cells, solar cells, and PEC could not operate. PEC electrodes typically form electron-hole pairs when struck by sunlight. In PEC photoanodes made of hematite, the generated holes must diffuse to the semiconductor surface, where they can oxidize water and form oxygen.

However, the electronic structure of hematite is such that the photo-generated holes tend to recombine with the electrons before reaching the surface. As a result, the resulting photocurrent is limited by the relatively few holes that actually do reach the surface. Recent efforts to optimize the nanostructured morphologies of hematite photoanodes have led to significant improvements in performance, but in spite of these efforts, the overall energy conversion efficiency in hematite remains at only about a third of its potential. An intelligent management of electron and hole transport is, therefore, critical for a better materials performance.

In this context, a better understanding of hole states at the hematite surface has been the subject of much interest as well as debate. It has long been suspected that in hematite, two types of holes with different water-splitting power are formed. The existence of different types of holes with disparate reactivity toward water oxidation has broad implications for the ultimate performance of hematite. But it is quite difficult to detect such holes, and studies of this phenomenon are complicated by numerous technical constraints. Moreover, the holes are transitional and quite elusive.

Not all holes are created equal

In a recent study published in the Journal of Physical Chemistry C, Empa researchers Artur Braun and Debajeet Bora and their colleagues from EPF Lausanne, the University of Basel, China and the US studied the nature of photoelectrically generated holes in a PEC that had been specially designed for gathering data while the cell is in operation ("operando"). They recorded soft X-ray absorption spectra under simulated sunlight and in the dark and identified two new spectral signatures corresponding to two different hole transitions, an O 2p hole transition into the charge-transfer band and an Fe 3d-type hole transition into the upper Hubbard band. According to Braun, this is the first time that the electronic structure of a PEC photoanode has been analyzed while it was in real water splitting action, i.e. in contact with electrolyte, under anodic bias and illuminated by visible light. "The preparations for this extremely complex experiment took us three years," says Braun. "After all, soft X-ray spectroscopy works only in ultra-high vacuum, and photoelectrochemistry works only in liquids. Combining both was technically a great advancement. Yet, I would say we were very fortunate to discover the two electron holes in an operating PEC."

Their groundbreaking experiment demonstrated the formation of two different types of electron holes at the semiconductor-liquid interface under the exact conditions, at which the photocurrent arises. Quantitative analysis of their spectral signatures revealed that both types of holes, contrary to earlier speculation and historical perception, contribute to the resulting photocurrent. "This is a milestone in the understanding of solar water splitting and encouraging news for researchers worldwide who are working to optimize hematite for PEC photoanodes," says Braun.
