Nano technology

There is a huge amount of interest in the development and use of nanomaterials, across a wide range of sectors. The properties of the micro-sized particles are perfect for application in everything from medical and pharmaceutical to clothing creation and the manufacture of filters, produced using the method of electrospinning.

Electrospinning, sometimes known as EHDP is method for the production of nano and micro-structures, and has huge benefits in industry. It can also be used for a range of materials to suit the intended purpose.

What are the benefits of using nano materials?

There are many benefits to electrospinning processes to produce nanomaterials. For example the surface area to volume ratio of nanofiber, due to the nanodimension of the fibers, is very high. Different materials, such as polymers, metals and ceramics can be spun together to give excellent results.

There is also a huge cost saving benefit. Although at the forefront of modern technology, setting up a lab or a clean room to carry out electrospinning is very cheap when compared with the set up of other industrial processes. Several companies have even scaled up the production of the nanofibrous membrane, to enable mass production at low cost. And setting up an electrospinning company is surprisingly simple, as staff can be upskilled quickly and efficiently to manage the process. Especially as there are machines now with incredibly easy user controls.

How does it work in practice?

If those who are are unfamiliar with the method behind electrospinning of nanomaterials can understand the process relatively simply. It involves using an electrical force to pull charged threads of polymer melts or solutions.

The solution of polymers, solvents and the other components is prepared. At this stage molecular chair entanglement takes place. Next is the electrospinning itself. The solution is fed through the capillaries and a high voltage is applied which creates a jet. The jet is then whipped and stretched into fibers. It is at this point the solvent is evaporated.

Finally the dry fiber is formed into a membrane or material, depending on the intended use. This can be quite wide ranging, and so although the science behind it all remains exactly the same, the electrospinning machines must be correct for the type of usage as defined by the manufacturer.

What are nanomaterials actually used for?

The materials are huge versatile. The limit for future innovations is only as small as the next person’s imagination.  It is currently used across medicine, for example growing artificial tissues that can mold with living tissue for example in place of a skin graft, or to create a barrier around an organ. It is also used in biomedical implants that sit under the skin and release a slow stream of drugs into the body.

They are of course also used in the production of fabric, particularly whether that fabric needs to be lightweight and breathable. In fact the initial development of electrospinning and micro or nano materials was initially developed by the textile industry. Especially where the wearer needs to be protected by toxic substances. It is the perfect way to make seamless non-woven garments.

It is also often used as coatings for other items, for example furniture, or pharmaceutical drugs. The process helps give products protection from the environment around it but also maintain the quality of the interior product within.

This is because of the properties of nanofiber. The previously mentioned high surface to volume ratio, and the fact that due to the electrospinning process at a molecular level the material is virtually defect free.

It is vital that, in order to achieve outstanding results, the chosen manufacturer of machinery is of the highest quality. It is very important. Particularly when trusting the machinery to produce highly technical fibers, with the right polymers, but the right equipment.

Nano materials bring to humanity technological advances that revolutionize industries, such as medicine, that greatly benefit the health of human beings. At the forefront of modern technology and its development and production, the potential for vastly improving human quality of life is huge. Even the current uses are just the tip of the iceberg as to what could be achieved in the future.

How Will Roads Change As Logistics Become Automated?

Published

road network automated

There have been a lot of big developments to be found inside the automated vehicle space over the last few years. With countless car companies throwing their hats into the ring, it’s only a matter of time until cars that don’t need drivers are able to spend more time on the road. Of course, though, personal transport is only one side of this, and the automated driving scene is much more likely to impact logistics in the short-term. But how exactly will this change the way that transport companies operate, and how will the roads you use be impacted by changes like this?

Increased Safety

Currently, many truck drivers have to push themselves to their limits to be able to get their work done. Long drives can easily be held up, but important deadlines can’t be missed without throwing off an entire schedule, and this leaves drivers having to miss sleep and drive long distances without breaks. A tacho card will usually be used to monitor this, making sure that drivers don’t break the law. Automated transport promises to solve problems like this, with digital machines never tiring and being able to work for days on end without having to take a break.

Greater Efficiency

Many transport companies have to use the roads at the same time as normal drivers to make sure that they can make their deliveries without pushing drivers too hard. This sort of approach wouldn’t need to be taken with automated vehicles, instead giving transport operators the chance to choose the quietest times to have their machines on the road. Alongside this, route planning can be more dynamic, with plans being changed on the fly to make up for things like traffic issues. Of course, though, as a big part of this, normal drivers may experience some strange behavior from the automated trucks that they see, especially when they are first starting to hit the road.

Convoys

While it may be something that changes in the future, transport companies are often more interested in systems that use convoys of trucks rather than simply sending trucks out on their own. This involves having a lead truck that is driven by a normal person, with several other trucks that tail safely behind it. This can make it much easier to have trucks follow specific routes without having to rely on GPS systems can lose signal or be disrupted in other ways. Of course, though, as a big part of this, many transport companies simply can’t afford the technology like this, and it could be a few more years until they start to be spotted when you’re out and about.

With all of this in mind, you should have a much better idea of how the automated logistics market is going to change roads over the next few years. The way that you drive will almost certainly change as time goes by, with more and more automated driving options becoming available all the time.

Matica’s CEO Sandro Camilleri speaks about security in digital payments

Published

secure digital payments

One thing is for sure: the COVID-19 pandemic accelerated many behaviors and trends that once were holding their pace. A great example can be found in digital payments and online shopping. According to Rakuten Intelligence, from March through mid-April, e-commerce spending in the United States increased more than 30% compared to the same period last year. When it comes to worldwide scores, it reaches the surprising increase of 74%.

Although books and cleaning products led the ranks mapped by Rakuten, specialists argue that digital payments and online shopping are here to stay, as much as it has already been observed in Asian countries. In this sense, securing financial transactions and protecting consumer data became a mandatory issue to be addressed both by companies and the government.

As a leading European company in the processing and printing of cards and identification documents for security systems, Matica Technologies is dedicated to granting safety and technological solutions to businesses dealing with financial transactions online. According to the CEO and founder of Matica, Sandro Camilleri, the advent of digital payments is a revolution similar to that which technology has caused and is currently causing in other areas, such as transports. “It is an inevitable revolution, which citizens will have to get used to, and which must therefore be managed in order not to risk unintended consequences, being the key issue obviously safety,” he argues.

Camilleri stresses that there are two different phases when it comes to digital payment security. A first one is about information and personal data storage, one of the greatest topics of our time and also a potentially enormous market sector. The second, less discussed though equally important, is guaranteeing strength and security for the financial transaction itself — and this is a purely technological issue. “The use of chips that are equipped with incredible memories, high precision lasers and holograms makes it extremely difficult, not to say impossible, for any attacker to clone a card produced by us. Secondly, the transaction must be secure thanks to specific and constantly updated software,” explains Matica’s CEO.

Now, when it comes to privacy, Camilleri states that people must be aware of what is at stake when data is leaked and why such occurrences are so alarming. With more and more appliances being automated and connected to computers and to the internet, such as is the case for cars and home security systems, cyberattacks could lead to consequences that are not only terrible, but tragic. 

In such situations, Matica’s CEO believes that only biometric data could spare individuals from having their systems hacked, though this data must be filed with care and used only for strictly necessary purposes. In any case, Camilleri argues that using biometrics is becoming day by day more inevitable with the increasing rhythm of automation, and this is a feature that can already be found in some of Matica’s available systems, such as is the case of the passport series.

Are You Aware Of Your Children’s Online Activity?

Published

on

There’s a big, wide, scary, often strange world out there, and it’s the task of any individual to grow into an adult and begin to contend with it. However, most responsible parents understand that showing the raw facts of life, or being introduced to bad influences is simply not suitable for a young child. They must learn slowly, with care, and appropriately to the degree we’re able to foster that environment. Parents cater to this by controlling what friends their children make, or what hours they may be allowed to spend time with them.

However, a growing cause for concern is the fact that many parents fail to keep their children safe online. The internet may as well be its own world, and it reflects our reality, both the good and the bad, the trustworthy and the terrible. This means that as a parent, it’s important to stay aware of your child’s online activity. If you can do that, you can better control the content they see, what they’re allowed to access, and the influences they are moved by.

Use Worthwhile Content Filters

It’s important to use the best content filters and parental controls you can. Some offer you access to limit internet time, while others help you block certain websites or content from being seen. With the best cyberbullying safety services, you can also ensure that your children are equipped to handle the unfortunate likelihood of encountering abuse online. The more you can engage in good habits now, and regulate their usage, the less likely they are to come to harm within the wild west that is the online world.

Understand The Trends

Understand the trends that occur and know how to deal with them. For instance, you might block access to certain apps or sites, but your child’s friend’s parents may not have the same philosophy. If you know the trends through paying attention to what they’re saying, you will be able to assess if they’re healthy or not. For instance, TikTok is now seen as a negative influence on many young children due to how poorly they moderate their content, and how limited content filters are in place. When you make decisions to help them stay secure, you are in effect limiting the vulnerable pathways in which they could become less safe.

Stay Alert

It’s important to say, but stay alert. If you notice your child is finding it hard to engage with social media, or they follow a risky YouTuber, you are within your right to restrict access or to observe more closely. It’s a tough job, but ultimately you cannot completely banish your child from the internet for the entirety of their childhood. It’s best to help them build healthy habits now and also know how to stay safe online than to pretend it doesn’t exist. To that end, you’ll be making the right choices.

With this advice, we hope you can better stay aware of your children’s online activity, and manage it as appropriately.
