But what if concrete could heal itself? Or asphalt, or even metal? It would be possible to save billions of pounds on repairs and restoration work alone, not to mention reducing harm to the environment that comes from replacing damaged materials.
Transparent wood is quite flexible, as it contains natural cellulose. In order to achieve transparency, balsa wood is soaked in a special solution and then epoxy resin is added to the structure. Transparent wood or wooden glass can be used instead of traditional glass units or other elements in building structures that have to be transparent, but also durable, eco-friendly, and energy-efficient.
Innovative building materials are not always materials with innovative physical properties like strength or safety. These can also be materials which integrate technology to deliver spectacular decoration and the implementation of the most extravagant design ideas. A new type of finishing building material is a sensitive tile with acrylic fiber which reacts to your movements, touch, or light sources. The optical fiber transmits light and reacts: the tile can twinkle, light up, catch and scatter neighboring colours on its surface. Decorating with this material provides new opportunities in architecture and interior design.
In addition to this bio-technology, there is another alternative from Korean researchers in which capsules of a certain polymer are added to concrete. Under the influence of moisture and sunlight, it also begins to react, swelling and filling the crack.
Traditional concrete is a very reliable and well-established building material, but it loses its properties when cracked. Many materials science specialists around the world are working on giving the base material a modern upgrade.
These days, almost all construction is based on concrete. We already mentioned that one of the problems of concrete is its fragility if it chips and cracks. Additionally, while concrete is extremely strong, it is limited in the load it can bear. Back in 2014, Singaporeans were able to not only improve the strength and reduce the weight of concrete by eliminating reinforcement in concrete structures, but they also added flexibility, which is not a characteristic property of traditional concrete.
Due to a unique additive, the new concrete ConFlexPave has gained flexibility and strength that is up to 3 times higher than that of traditional concrete. The thinnest polymer microfibres are mixed into the solution, distributing loads across an entire slab of concrete. This helps it to become as strong as metal and twice as strong as regular concrete when it is subjected to bending.
The patented Concrete Canvas solution is used for a wide range of construction tasks and more. It allows concrete structures to be built with minimal installation and specialist training. Installation is usually ten times faster: just unfold a prepared roll and add water.
This is an ancillary material that facilitates a number of pre-construction works and is also used in the preparation of infrastructure facilities: canals, repairing and protecting surfaces and slopes and strengthening reservoirs and pipes.
In Flexicomb, thousands of polypropylene tubes are tightly connected into a flexible matrix, which can be given different shapes. These structures are translucent, so they are often used for the manufacture of decorative lighting elements.
This provides a perfectly pure white with a reflective effect. According to the test results, the implementation of the paint leads to incredible results: painting a 90 m2 roof delivers a cooling capacity of 10 kW. This figure is higher than the typical power of home air conditioners.
Berlin-based startup Made of Air has developed a special non-toxic bioplastic made of biochar from forest and agricultural waste. It captures carbon and can be used for everything from building facades, furniture, interiors, transport and urban infrastructure.
Researchers from Rensselaer Polytechnic Institute in the USA have invented a hemp alternative to steel reinforcement, which they claim avoids the problem of corrosion and reduces carbon emissions during construction.
Hemp reinforcement can be used to support concrete structures in the same way as steel and other reinforcement is used today, but with less environmental impact due to both the composition of the material and its durability.
Currently, the rusting of steel reinforcement is the main reason for the premature demolition of structures such as bridges, roads, dams and buildings. Innovative hemp reinforcement will provide three times the durability and protection against corrosion. Moreover, unlike glass fibre reinforcement in structures that are particularly susceptible to corrosion, hemp reinforcement does not require so much energy consumption to produce and install, which makes it an environmentally friendlier solution.
This list is a just a small fraction of the developments that are already in use in the construction industry. Each of the materials is being improved every year, or one solution is replaced by another, even better option. Construction is an area where technologically advanced materials and innovative digital solutions can revolutionise the way projects are run and create truly futuristic objects.
Image of the galaxy IRAS F11119+3257, an Ultra-Luminous InfraRed Galaxy (ULIRG) hosting an active black hole at its centre. ULIRGs are systems undergoing a galactic merger between two gas-rich progenitors, on the way to becoming an elliptical galaxy.
The background is an image from the Sloan Digital Sky Survey, while the inset is a red-filter image from the University of Hawaii's 2.2 m-diameter telescope. The inset shows faint features that may be tidal debris, a sign that this object is undergoing a galactic merger.
Astronomers studying the supermassive black hole at the centre of this galaxy have found proof that the winds blowing from the black hole are sweeping away the host galaxy's reservoir of raw star-building material.
This finding was made using ESA's Herschel space observatory, together with the Japanese/US Suzaku X-ray astronomy satellite. Combining these data, the astronomers detected the winds being driven by the central black hole in X-rays, and their global effect, pushing the galactic gas away, at infrared wavelengths.
There is a lot of good information about fly tying out there. Between books, magazines, and the Internet, there is no shortage of adequate instruction and advice on almost all aspects of fly tying. Except for the apparent stepchild of fly tying: thread. Much of what's been written about this important tool is false or misleading.
Note that I used the word "tool" rather than material. In my mind, thread is a tool chosen to perform a specific task. I own no less than 1,000 spools of thread in a huge range of sizes, colors, and configurations, and while every one of them is good for something, none are good for everything. A large selection lets me choose the right tool for the job in every instance. You don't need 1,000 spools of thread, but hopefully I can help clear up the details of why threads are different, and what those differences mean to you.
Before I get started on thread differences, let's talk wax. Almost all tying thread comes from the factory waxed, and if you want unwaxed thread you'll have to use silk, GSP, Kevlar, or a specialty thread like unwaxed 3/0 Danville's Monocord. Waxed thread is not a substitute for dubbing wax, and is applied to the thread in the manufacturing process merely to keep the thread from fraying and unwinding wildly when it breaks.
Size is another major source of confusion for many consumers. Historically, fly-tying thread was sized using the archaic aught system that came originally from sizing silk surgical sutures, and is still used today for that purpose. Using a zero as a baseline and additional zeros to denote smaller sizes, the aught number described relative size based on a range of diameters and worked nicely in an age of organic materials where exactness was not always possible. Many tying threads are still measured this way today, as an example, 000000 or 6/0 (six aught) being smaller than 000 or 3/0 (three aught) thread.
The Danville Chenille Company used this system for tying thread for 50 years with no issues, but in the 1990s, UNI Products entered the tying market. While UNI also used the aught system to distinguish its larger and smaller threads, the company used a different baseline diameter, and that's where everything went to hell. Using the aught system, tiers assumed that the new 8/0 UNI-Thread was smaller than 6/0 Danville's. And 6/0 UNI-Thread seemed much stronger than 6/0 Danville's. Despite the numbers on the spool, those comparisons weren't fair because the two threads aren't the same size at all.
There is no constant baseline used by all manufacturers to clearly and accurately label their threads. As tiers, we should all know that 70-denier UTC Ultra Thread, 6/0 Danville's Flymaster, and 8/0 UNI-Thread are all about the same weight, but we should also know that these three threads are still very different because of both the materials used to make them, and the configuration (round or flat when viewed in cross section).
Danville's and UTC Ultra Thread are both made of nylon. Nylon has a fair amount of stretch, (25 to 30 percent), naturally lies flat, and has a silky smooth finish and a glossy sheen. Nylon threads allow dubbing to slide more than polyester threads and while still perfectly usable for dubbing, you should expect poorer adhesion to a slicker thread.
Both of these threads are flat and wrap on the hook like a ribbon. They are configured with multiple strands held together with a binder strand twisted around the center strands to hold the thread together. UTC Ultra Thread lies flatter on the hook because it is held together with a binder strand that twists around the main core at a rate of only one revolution per inch. This open twist allows the thread to spread out and lie flat on the hook shank. Danville's has a binder strand with more revolutions than UTC Ultra Thread so it doesn't lie quite as flat.
