Deep frying might not simply be a method for the making of tasty chicken-- according to S. Korean researchers it might also be key in the making of batteries and supercapacitors with enhanced power storage capabilities.

In this case the "deep frying" consists of spraying graphene oxide droplets into a hot (160℃) blend of acid and organic solvent. The process evaporates the water inside the material, causing it to clump into 3-dimensional "pom-poms."

The 3D pom-poms are important, as battery electrodes require a large material surface area for the exchange of electrons. To test such capabilities the researchers built 1 x 1cm electrodes full of 3D graphene, which they say show a capacitance of 151 farad per gram compared with 118 F/g for the plain graphene electrode.

Kensington launches the KeyFolio Thin X3 Plus for iPad Air 2at CES 2015-- an upgraded version of the KeyFolio iPad case featuring a 4500mAh battery and a companion PowerLift power management app.

According to the company the battery can charge an iPhone 2-3 times, as charges an iPad by up to 50%. The case also features an integrated Bluetooth keyboard with 6 rows of high-performance scissor keys within a form-fitting hard shell complete with aluminium accents.

The keyboard automatically switches on and off when engaged or disengaged from the magnetic stand, while a "QuickFold" design allows easy transition between typing and viewing modes.

If there's one product category that is more than well represented at CES 2015 that's the smartwatch, with offerings in all shapes and sizes launched by companies perhaps less known for dabbling in such technology.

One such example is Garmin, who revealed not one, not two, but three smartwatches. These are the Vivoactive (the company's first dedicated smartwatch), the rugged Fenix3 and the GLONASS-enabled Epix. All feature the usual email/text/social media notification features, as well as Garmin-powered navigation and a newly launched Connect IQ app store.

Meanwhile budget mobile maker Alcatel presents an affordable smartwatch-- the Onetouch Watch, a sub-€100 device previously known as the "Wave." Available in either plastic or all-metal versions, the Watch features a round 1.2-inch display and runs on proprietary software.

Griffin Technology releases four mobile device charging accessories at CES 2015-- the PowerDock Pro 5-slot charging slot, the 3-port PowerBlock 3 wall charger, the PowerBlock Wall Dock and the 12V PowerJolt Premium car charger.

The PowerDock Pro features 5 slots and ports for customers to store and charge multiple devices from a single power source, with 12W of power and what Griffin calls "ChargeSensor" circuitry to optimise charging for each device. The charging slots carry devices without need for removing from cases, and a built-in cord management system complete with hidden compartment takes care of cables.
