4D printing and the Its current Scenario

4D Printing is a self re-configuring printing technique that utilizes special material to enable changes upon time. The fourth dimension of 4D Printing refers to the material that are able to change and mutate over time. The changes may occur upon exposure of water or air or change in temperature.

4D Printing

The technique of this type of technology enables designers to define characteristics of the material they are made from. To enable specific attribute and functionality the printed material goes through sophisticated chemical calibration.

Principle of 4D printing:

Different material properties when programmed into each of the various particles of the designed geometry and harnesses, the different energy/element absorbing properties of the materials triggers to activate the self-assembly process.

Application of 4D Printing:

  • Fun toy like self-folding origami, self-folding Furnitures
  • Designs of complex structures, Space shuttle or even the International Space Station
  • Smart Water Pipes, with Self Healing Characteristics
  • Medical Use and Organ Replacement
  • Smart Bricks, Smart Rods that have healing capacity.

Future Remarks:

4D printing is expected to be used extensively in the future. In the developing stage , the ideas include the development of clothing that responds to environmental stimuli to maximize wearer comfort. The medical industry is also expected to make use of 4D printing as shape changing 4D prints are expected to be more compatible with the body than rigid metal supports.

The 4D Printing technique is an emerging market potential whose efficiency is expected to increase. This printing technology is still in the early phase and software and hardware are not yet to be established. The trend of 4D printing will be increase when industry sector and health sector will start using it.

Xiaomi, the Chinese smartphone manufacturer, recently unveiled its new Redmi note 3- a midrange device with quality features and affordable price. So today we will point out the pros and cons of the Xiaomi Redmi Note 3 which will help u decide if the phone is right for you or not.

Pros of the Xiaomi Redmi Note 3

  1. Full Metal Body:

The redmi note is very well designed with full metal body. The metal gives the phone a sturdy and premium look. The looks of the phone is similar to its predecessor redmi note 2 but the material in note 3 is aluminum metal. It’s certainly great to see Xiaomi bringing full metal body design to its midrange device.

  1. Fingerprint scanner:

Fingerprint scanner has become a must for most people. We can see many devices having it and Xiaomi offering this feature in redmi note 3 will certainly attract people towards it. The fingerprint scanner here is located at the back and is quick and responsive; the scanner unlocks the phone in 0.3 seconds.

  1. Battery:

Redmi note 3 has a huge 4,000mah battery. So with such large battery, the battery life of the phone is great. Some tests suggest that the note 3 offers around 264 hours of talk time over the 3G network. Redmi note 3 will last you one day and a half with good usage.

  1. Processor:

Xiaomi has opted for 64-bit MediaTek helio x10 processor clocked at 2gHz. There are two variants of this phone one with 2gb ram with 16gb of storage and another 3gb ram with 32gb of storage. The helio x10 is a great performer inside such an affordable phone and the chipset can handle all tasks on redmi note 3’s 1080p screen.

  1. Camera:

Redmi note 3 features a13MP rear camera with dual tone flash and a 5MP front camera. The rear camera has a hybrid autofocus system that helps in faster and more accurate focus. The picture taken is of good quality although not comparable to the likes of flagships. Nonetheless, the picture and video quality is great for a midrange device.

Cons of the Xiaomi Redmi Note 3

  1. No microSD slots:

With only 16gb and 32gb of storage to choose from some people will be disappointed, as people wouldn’t be able to expand the storage with an external microSD card.

  1. Average 1080P display with No scratch resistant screen:

The 1080 display here is an average unit. The contrast ratio, color accuracy as well as the sunlight legibility is average. Moreover, the screen is not scratch resistant as it doesn’t have gorilla glass or dragon trail glass. So if you are not careful with it, the screen can get scratch easily.

All in all, despite having some few cons, it is still one of the best phones to buy for $200 and we totally recommend you to go for it as it has a nice metal design, a big screen, fast CPU and a decent camera.

5 Reasons to Buy Lenovo K4 Note, 2 Reasons to Pass

0

Lenovo’s latest midrange flagship is a wonderful phone and offers a lot for an asking price of Rs.27,499. Despite packing some great features, the phone has some downsides to it too. So, here are the 5 pros and 2 cons of the Lenovo K4 Note.

PROS OF LENOVO K4 NOTE

1. Display:

The K4 Note has a 5.5-inch Full HD IPS display with a 1080 x 1920 pixels resolution and 403ppi pixel density. Apart from being a full HD display, the K4 Note screen offers good brightness and contrast. The K4 Note display comes with Gorilla Glass 3 protection and is scratch resistant. The display is quite bright and is easily visible in the outdoors during the daytime. Since the phone is mid-ranged, having a 1080p screen sounds good for the price.

2. Audio:

The Lenovo K4 Note also comes equipped with two front-facing speakers alongside Dolby Atmos audio system. I believe due to the stereo speakers, the phone offers a significantly better and louder sound output. The front facing speakers are great when watching movies, playing games or even listening to some music. It’s nice to see Lenovo bring this feature to an affordable smartphone like the Vibe K4 Note.

3. Battery:

The Lenovo K4 Note boasts of a large non-removable 3300mAH battery. The battery should easily last you one full working day. It has around 5hrs to 7hrs of the screen on time. K4 note charges from 0 to 100% in about 2 hours 15 minutes. With a 1080p display and average processor, the k4 note provides good battery life.

4. Fingerprint scanner:

It’s nice to see Lenovo throwing in a fingerprint scanner into the mix which is fast becoming an industry standard. The scanner is quick and responsive. Apart from being a security feature in a phone, the scanner can also act as a shortcut for the home button.

5. Price:

The smartphone is bang for the buck and you will definitely enjoy the positive features of the smartphone. Only at around $199 you get a phone with good looks, metallic frame, front facing speakers and fingerprint scanner. The phone comes with good specs for a mid range phone. Overall, I think that getting those good features at such an affordable price is a good deal.

CONS OF LENOVO K4 NOTE:

1. Processor:

Lenovo has decided to go for the 64-bit MediaTek MT6753 octa-core processor clocked at 1.3GHz and it is combined with the GPU Mali –T720. The processor is coupled with 3GB RAM. While the 3GB RAM is very well enough for day-to-day usage and multitasking, but high-end games such as Asphalt 8, modern combat lags. So if you like playing games with good graphics this phone is not for you but if you don’t then the processor can easily handle simple tasks thrown at it.

2. Heating problem:

The phone may not heat up that frequently but you will definitely feel the phone getting warmer during playing games and multitasking. The phone feels slightly warm on the back with normal usage but it is not a major problem. Also, while using 3g the phone gets warmer.

Mobile phone and it’s adverse effects: should you start worrying?

Mobile phones, from a long time are associated with the root of various complications in the body. Despite that, the growth of mobile phone user is increasing day by day. Mobile phones have become more advanced that almost every work that was only done on desktop or laptop is now done on them. It has become an integral part of many people’s life. The radiations of mobile phones are said to be strong enough to damage soft tissue but weak to alter the DNA.

Low count of sperm in men is a problem which is on a rise these days. Various scientific research suggests that men who put their mobile phones in their trouser’s pocket are likely to have lower sperm count than those who don’t. Experts are warning men to decrease the use of the phone as it is associated with “cooking sperm” and causing lower sperm count which will affect while a couple tries to conceive a baby.

Whereas there are no any published studies about the effects of mobile phone radiation on women’s reproductive health. The study by specialists suggests that men who keep their phone in their pocket are seriously affected in 47% cases compared to 11% in general population.

The risk of eye vision problem is also associated with the use of mobile phones. It is said that due to smaller displays in mobile phones you are squinting and likely straining your eyes while using them which decreases the vision. So it’s best to use them as little as possible or prefer larger displays for doing many tasks.

The brain activity is also likely affected due to mobile phones. A scientific study concluded that acute cell phone exposure affects the brain’s metabolic activity however the study didn’t say anything about possible carcinogenic effects of the mobile phone. The electromagnetic interference can also can mobile phones to interfere with the operation of pacemakers and some hearing aids while the interference is said to be reduced on 3G and newer systems.

stats-mobile-brain

The electromagnetic interference can also can mobile phones to interfere with the operation of pacemakers and some hearing aids while the interference is said to be reduced on 3G and newer systems. Since mobile phone cannot be completely avoided to be safe from all of its adverse effects, what we can do from our side is to lower the use of them and look for their alternatives.

CAT S60 announced with thermal camera and strong build

1

CAT, a company that produces huge machines mainly for construction works and other heavy works, has developed a phone with a rigid and sturdy build, as expected from such a company, which has an integrated FLIR thermal camera. Running on Android 6.0 Marshmallow, the CAT S60 offers other feature like water resistant and the ability to withstand a few drops.

The built of the phone is purely rugged and bulky. The S60 has strengthened die cast metal frame and carbon fiber look-alike toughened plastic on the rear. According to the manufacturers, the handset can hold out against drops onto concrete from up to 1.8 meters. In addition to that, the phone is dust-proof and waterproof. The S60 can be used up to 5m of depth underwater for an hour with all of the switches closed for speakers and microphones. Without the switches closed, the phone can only withstand 2m of depth underwater.

Thermal cam CAT
FLIR Thermal Camera

Well, we have already seen add-on thermal camera modules for iPhones and Android but this is the first phone that has FLIR thermal camera built in. so, there are basically two rear cameras; one normal 13MP camera and the other very special thermal camera. The thermal camera records the heat data and with the help of the app, a simple tap on the screen gives the approximate temperature of the object.

Looking at the physique and features of the C60, it looks like it’s made to be used by a construction worker, plumber, electrician or someone who has to work under harsh environment. Normal users would like to stay away from its midrange processor and its bulky built. The physical aspect isn’t that appealing as well. But the dustproof and waterproof feature would certainly attract people who have to work around lakes, ponds, or places where there are too much of dust. The phone’s thermal camera could certainly be a plus point for an electrician to find the heat dissipation in circuits and other circuit elements. Also, people who work with fires like in factories, and people who constantly need to check the temperature of certain objects and machines can benefit from the thermal camera on this phone for easy measurement and convenience. The camera can see through smoke with the help of its thermal sensors, and this can be useful for a person who needs to deal with smoke in their work or for any case of that matter. And this can be used in search and rescue missions where bodies might be hidden by smoke. Again, the thermal camera would not be that much beneficial for normal users but they certainly can win the bragging rights among friends by showing off the awesome feature.

Other specs of the phone include:

  • 4.7-inch 720p display with wet finger and glove support
  • Screen is shielded with 1mm gorilla glass 4
  • 13MP main camera with dual-LED flash and 5MP front-facing camera
  • Snapdragon 617 octacore processor (1.5 GHz) coupled with Adreno 405
  • 3GB of RAM and 32GB of internal storage, expandable using microSD
  • Wi-Fi, Bluetooth, 4G LTE connectivity
  • Large battery of 3,800mAh capacity

CAT S60

So, CAT S60 was announced at MWC 2016 and it will be made available later this year for $599 in the U.S. People might be overwhelmed with the pricing for the smartphone with such midrange specs but keep in mind, it features the ruggedness from CAT and a built in FLIR thermal camera.

CG launches EON Edge Smartphone

0

CG smartphones have been in the Nepali market for less than a year and we can already see the wide customer base it has created. It is safe to say that CG has got a fair market share on mid-range smartphones with decent performing hardware at a reasonable price.

No doubt CG smartphones are one of the most good looking phones in its price category. They feel great on hand and, for the most part, doesn’t feel cheap. Now, CG has introduced yet another mid-range phone to their EON line up, CG EON Edge for Rs.11,999.CG EON Edge

What’s inside CG EON Edge?

Don’t get fooled by the name. By no means, this phone has a curved edge display like the Samsung Galaxy Edge series. Instead, it is rocking a 5 inch 720p IPS display with the resolution of 720*1280. It is powered by 1.3GHz processor (Unspecified) backed up by 2GB of RAM. EON Edge comes with 16GB Internal storage with the option to expand via Micro SD card up to 32GB. As far as the camera is concerned it has 13MP Rear Camera with auto focus and 5MP Front-facing Camera. The device being launched in 2016 still runs on Android Lollipop 5.1 with no signs of future updates. Powering this device is a 2000mAh battery which should give a decent battery backup keeping account of the hardware configuration. The only turn off for this phone can be its single SIM capability as most of the mid-range phones come with the option of dual SIM.

To conclude, CG EON Edge doesn’t bring anything new to the table. It has the same hardware configuration like the Moto E, Gionee P5W, Huawei Honor Holly, Colors Elite E10 and almost all smartphones at its price range. But design wise this phone is ahead of every other product in its price category.

Samsung Galaxy S7 set to launch in Nepal on March

0

Integrated Mobility Solutions (IMS), the authorized distributor of Samsung smartphones in Nepal, has confirmed via its official Facebook page that the new Galaxy S7 will arrive in Nepal next month. The Samsung Galaxy S7 was recently launched at the Mobile World Congress and offers a 5.1-inch Quad HD display, 4GB of RAM, and 12MP camera.

Key Highlights of the Samsung Galaxy S7: 

  • Android 6.0 Marshmallow
  • 5.1-inch Super AMOLED screen with 2,560 x 1,440 Pixel Resolution
  • Either 32 or 64 GB of storage, Micro SD card slot expandable up to 200GB
  • 12 Megapixel Camera with f/1.7 aperture and smart OIS
  • 5 Megapixel Front Shooter

  • 3,000 mAh battery
  • Qualcomm Snapdragon 820 processor (or Samsung’s Exynos chipset in some regions)
  • 4GB LPDDR4 RAM
  • Colors: Black onyx, Gold Platinum, Silver Titanium

Pricing in Nepal: 

We can expect the base variant of the Galaxy S7 to launch for around Rs. 80,000, considering a global pricing of $750. We might not see Samsung launching the 64GB version since the phone now offers microSD card support up to 200GB.

There is no confirmation from IMS on whether Samsung Galaxy S7 Edge will be launched or not. The Galaxy S7 Edge is a bigger variant of the Galaxy S7 that features a 5.5-inch display and rounded edge on the sides. Unlike last year when only the Galaxy S6 was launched, we hope that the Edge variant is made available, since it offers bigger yet compact display, a larger battery of 3600mAh and will cost only around Rs.10,000 more.

Enhanced Features in the Samsung Galaxy S7

  • Water and Dust resistant design: Both the Samsung Galaxy S7 and Galaxy S7 edge are water Resistant. With an IP68 rating, the device can withstand up to 5 feet of water for around 30 minutes.
  • Advanced Camera: The Samsung Galaxy S7 and Galaxy S7 edge feature technology that allows for faster autofocus and captures high-quality low-light photos.
  • Fast wireless charging: Its now possible to wireless charge and fast-charge your device at the same time with a wireless Fast Charging stand.
  • For the Galaxy S7 Edge: A new Task Edge screen offers one-tap access application, quick user’s favorite activities, favorite contacts, instant publishing tools, as well as activities for third parties, such as the news and sports results.
  • Dedicated Gaming Feature makes it easier to record sessions and screenshots. A do-not-disturb mode blocks incoming notifications and lets the user play games without interruption
  • “Always-on” display, a familiar feature of Nokia phones for years, the display shows time, calendar or images from the lock screen. This Screen is customizable apart from LG G5 which does not possess that customizable feature. The Always on screen is a SuperAMOLED screen which consumes only 1 percent of battery in an hour.
