How Nanotechnology Could Change the World

 

Nanotechnology is one of the most exciting and promising technologies available today. It drives innovation in a variety of sectors and allows industrial designers to create entirely new properties through the controlled manufacture and structuring of materials.Of late, the technology has been applied in many sectors, and it has opened the doors of implementation in many other areas where it will play a significant role in shaping the future and growth of the world.As scientists continue to experiment the many new ways nanotech will bring about a positive outcome, we look at some of the applications that will have the most impact in the world.

What is Nanotechnology?

Despite the hype surrounding it and its perceived potential for many diverse fields of science, nanotechnology can be difficult to comprehend. This is not surprising considering it’s a wide field. Nanotechnology refers to a technology that involves working with materials at the scale of one billionth of a meter. In other words, it relates to a technology that is between 1 to 100 nanometers in size. The prefix “nano” refers to one billionth. Nanotechnology scientists use atoms and molecules to make amazing new technologies that help improve electronics and nearly all aspects of modern life.

Benefits and Applications

Nanotechnology has several advantages and applications across a range of industries:

  1. Treating spinal cord injuries

Nanotechnology has shown significant potential in the treatment of spinal cord injuries. Scientists at the Institute of BioNanotechnology in Medicine at Northwestern University have shown that nanotechnology can be used to stimulate the body to heal itself by injecting “molecules that were designed to self-assemble into nanostructures in the spinal tissue.” When injected into the bloodstream with a syringe, these molecules repair damaged neurons, preventing the damage caused by inflammation and scarring.

  1. Heal injuries and restore organ function

In addition to being a breakthrough in the treatment of spinal cord injuries, nanotechnology offers exciting results when it comes to repairing injuries and restoring aging tissues. Scientists at The Ohio State University developed a new technique, called tissue nanotransfection, which helps to turn skin cells into other types of functional cells that can then be used to repair or restore function to damaged tissues such as nerves, blood vessels, and organs, among others.

The procedure uses a tiny device that is placed on the surface of the skin to replace injured or compromised organs by incorporating some new genes into them. Using the technology, the researchers successfully fixed mice that had lost blood flow to their legs within 14 days. Plans are underway to start clinical trials in humans as soon as possible.

  1. Generating electricity from motion

Researchers at Vanderbilt University developed an ultrathin device that produces electrical current from human movement. The device, which is made up of layers of very thin black phosphorus and is powered by battery technology, harvests energy when it is pressed or bent during human motion.

When the black phosphorous nanosheets are bent or pressed, this action produces an electrical current that is then tapped and stored in the battery. This has been made possible by the thin size of the sheets, which makes it easier to incorporate them into clothing as well as the ability of the nanosheets to harvest energy at low frequencies. The nanosheets can generate electric current at movement speeds as low as 0.01 Hz.

This means that energy can be harvested from one movement cycle every 100 seconds from everyday activities such as walking, sitting, and standing. The Future is in Nanotechnology Globally.

The 5 Most Important Skills of an App Developer

How Important is App Development For You and Your Business

When it comes to the world of app development, it is safe to say that app developers work in one of the most fast paced and evolving industries. Their skill set is required to evolve continuously and only the very best are considered to be at the forefront of innovation in such a competitive field. While in the past app development involved a more specialised focus, today our applications developers tend to be penned as needing to be a jack of all trades. While understanding how things are developed is essential, there is also the added fact that they must understand app security and a range of other services too.

User experience

User experience can be attributed to a range of different factors and what is becoming more significant is the fact that the expectations of users has increased dramatically in recent years. Today users have become more used to apps and the way that they work and this, alongside the fact that they have options, is precisely why app developers are faced with additional challenges with their work.

 

Javascript

The argument for which programming language is most important and significant when it comes to app development is something that has been under much contention since the time when app building began. Java programmers will argue that PHP not as effective whereas the latter will argue otherwise. Learning Javascript is among one of the most popular options for app developers which is why this skill is so worthwhile to learn if you are looking to become an app developer yourself. You can enrol on a Javascript course easily and learn while on the job. There is even support in the form of an essay writing service if your course requires you to test your theory skills alongside the practical aspect of the course.

Agile Experience

One of the other important skills that an app developer will need to be familiar with is that of working under an agile methodology. Agile is essentially a software development method that offers a continuous and adjusting stream of responses to various problems that may crop up along the process of a project. These solutions are established through the use of self-organised teams that work in a cross functional manner, thus forming strong collaborations as a result.

A degree

While it is not the be all end all to have a degree in order to become an app developer you will most certainly need to have some form of academic qualifications, whether this is collected through experience working for a company or completing short courses, this is something that is vital to get into such a highly competitive industry. Essentially, the most important thing is to be able to ‘wow’ your hiring manager with a range of skills that will really highlight that you know your stuff when it comes to creating apps that are of a high standard.

App developer jobs are highly sought after, so if you are looking to find work in an exciting and constantly evolving industry and are highly computer literate, then this may be the position for you!

What is the Antikythera Mechanism

Learn About the Incredible Antikythera Mechanism

As far as science and technology go, the Antikythera Mechanism is one of the biggest and most intriguing stories ever told. But what exactly is the Antikythera Mechanism and what makes it such a significant discovery?

What is the Antikythera Mechanism?

The Antikythera Mechanism is a device used to monitor and forecast solar cycles. The mechanism, which is often described as the world’s “first analogical computer,” is believed to have been used by early astronomers to mark the calendar as well as predict solar and lunar eclipse by tracking the movements of the sun, moon, and planets.

The Antikythera Mechanism was also used to plan a four-year athletics tournament cycle like the Olympic Games. Technically, you would be right to call it a calculator, as it was used to add, multiply, divide, and subtract. In addition, the relic could align different cycles and show the position of the sun and moon in the zodiac.

The device, a complex system, comprises over 30 sophisticated bronze gears held in a wooden and bronze case that’s about the same size as a shoebox. These gears were used to control dials tracking the moon, sun, planets, eclipses, as well as the schedule for the Olympics.

When Was the Antikythera Mechanism Discovered?

In 1900, a boatload of Greek sponge divers was blown off course by a storm, forcing them to take shelter by the small Mediterranean island of Antikythera, per LiveScience. The following day, they went diving off the tiny island and found the wreck of an ancient trading ship believed to be 2,000-years-old.

The divers later retrieved three flat pieces of corroded bronze from the submerged ship, which many believe sank between 70 BC and 60 BC on its way to Rome from Asia. Researchers say the device was first made sometime between the second and early first century.

Two years after the discovery, Greek politician, Spirydon Stais, who spearheaded the ship’s underwater excavation, visited the museum where the treasures from the wrecked cargo ship were kept. While sifting through the items, Stais was attracted by some fascinating pieces of bronze, which would later be known as the Antikythera Mechanism.

The Antikythera Mechanism’s True Purpose Finally Discovered

In the decades past, scientists have made several attempts to find the actual purpose of the Antikythera Mechanism using X-rays and CT scans to look inside the device. Despite several efforts, it wasn’t until 1951 that Derek J. de Solla Price found the real purpose of the “computer.”

Assisted by Greek nuclear physicist Charalampos Karakalos, Price took a complete X-ray and gamma-ray images of the device’s 82 fragments. His research showed that the mechanism’s primary gear represented the calendar year, while the smaller, unconnected gears were designed to serve as the celestial bodies, cites an Independent article.
