Have you ever heard of self-healing materials?

It may sound like science fiction, but this innovative technology is now a reality. Self-healing materials have the ability to repair damage to themselves without any external intervention. This technology has the potential to revolutionize a wide range of industries, from aerospace to construction.

Self-healing materials are made up of tiny capsules that contain a healing agent, such as a resin or polymer. When the material is damaged, the capsules rupture and release the healing agent, which then fills in the cracks or other damage. The healing process can happen automatically, without any need for external intervention or repair.


One of the most promising applications of self-healing materials is in the aerospace industry. Aircraft components are subject to high stresses and are often damaged during flight or normal use. Repairs can be expensive and time-consuming, but self-healing materials have the potential to reduce maintenance costs and improve safety. For example, self-healing composites could be used in aircraft wings to repair damage caused by stress or impact.

Self-healing materials also have potential applications in the construction industry. Concrete, for example, is subject to cracking and degradation over time. Self-healing concrete could potentially repair these cracks and prolong the lifespan of the structure. This could have significant implications for infrastructure projects, as well as for reducing the environmental impact of construction.

Another potential application of self-healing materials is in consumer electronics. Many electronic devices are subject to wear and tear over time, leading to damage or malfunction. Self-healing materials could potentially repair these devices automatically, without the need for costly repairs or replacement.

While self-healing materials are still in the early stages of development, the potential applications are numerous and exciting. This technology could potentially reduce the need for costly and time-consuming repairs, improve safety in high-stress industries, and even reduce the environmental impact of construction. As self-healing materials continue to evolve and improve, we can expect to see them being used in a wide range of industries and applications. The future of self-healing materials is bright, and we can't wait to see where this innovative technology will take us.

How the Advantages Outweigh the Disadvantages


 Painting from Photos

BY NANCY TANKERSLEY

(NancyTankersley.com)

Nancy Tankersley is on the workforce for Plein Air Live, a virtual craftsmanship meeting occurring April 15-17, 2021, with a novice's day on April 14. Register early and save!


Since the coming of photography in the mid nineteenth 100 years, craftsmen have involved the camera as a device in picture making. The Photorealists recognized the advanced world's large scale manufacturing and multiplication of photos, and deliberately duplicated photos. Yet, for craftsmen educated in the custom of working from life, the utilization of photograph reference was viewed as "cheating." I went gaga for the painterliness of Commander, Degas, and Zorn right off the bat, and recognize that most frequently their work was painted from life; yet I've been painting from photos since I originally got a brush. Like the painters who were early clients of photography, I was dependably a piece humiliated about my utilization of the photograph.


My earliest preparation started with examples on drawing, concealing, and point of view from "Figure out how to Draw" by craftsman Jon Gnagy, which I "acquired" from my more seasoned sibling. From the primary example, I can't escape the possibility that I might actually figure out how to draw as well as Gnagy. I followed his activities and started to portray things I saw around me, yet when I got a paintbrush to endeavor to paint the top of a youthful Vietnamese youngster whose photograph I found in Public Geographic, my long undertaking with the photo was making excellent progress so far. Sometimes I drew pictures from life of my companions and family members, who might stand by for 30 minutes, however Public Geographic gave fascinating photographs of individuals I had never met and puts I had never been.




Years after the fact, when I started my expert vocation as a craftsman while living in Jacksonville, Florida, I arranged many picture commissions of kids and grown-ups, every one of them from photos I took. Shooting huge number of photographs while chasing after youngsters in 90-to 100-degree intensity and moistness, I frequently felt more like a picture taker than a painter.


Yet, I was looking for that one articulation that was generally valid for every youngster, and with the assistance of the guardians we were normally ready to see as the right one. Frequently, while working from life, the subject falls into a represent that is more serious than they typically look, however the photograph can catch that momentary articulation that is so normal for the person.


Simultaneously, I was taking picture examples at night from Cleve Mill operator (a contemporary and companion of David Leffel), where we just worked from life. I additionally painted still life in my studio whenever I got the opportunity. Yet, as a mother with small kids at home, and a flourishing representation business, the undeniable benefits to working from photographs in the comfort of my home studio couldn't be disregarded.


In those years, which were loaded up with raising my family and regular moves as a Naval force spouse, the photograph was as yet my essential reference source. By then I was showing my metaphorical work and, surprisingly, a periodic scene in displays. In 2000, be that as it may, when I previously joined the Washington Society of Scene Painters and started painting en plein air consistently, I started to completely acknowledge where I had been going wrong.


I tracked down the experience of interfacing with what is straightforwardly before you, without any channels or mechanical devices changing your discernments, to be a significant and fundamental one. Drawing and painting from life works on your capacity to see unpretentious contrasts in tone and temperature. All things considered, while working from life you are seeing items in their aspects; with a photograph you are all working with two aspects as it were.


Life perception additionally fabricates your visual memory and comprehension of how light influences structure. With enough involvement with working from life, a comprehension of essential shapes and light source, and the capacity to imagine to you, you in the end find you can create items and even individuals when expected to work on a piece.



In this painting I was attempting to convey a thought. The scene is the migration gateway at Philadelphia Global Air terminal. I added figures, changed the posture of the primary figure and adjusted the banner to add accentuation to my unique thought.




Figuring out that painters have involved photography as a guide since the camera was created was a disclosure and confirmation that I hadn't deferred my painterly improvement irreversibly! Starting around 2000, exhibition hall custodians and specialists have recognized the spot photography has had in a considerable lot of the extraordinary compositions of the most recent 150 years. It has been irrefutable that aces who in some cases utilized photograph reference incorporate Degas, Zorn, Picasso, Gaugin, Sorolla, Lautrec, Cezanne, and even Van Gogh.


Edgar Degas loved the camera and, surprisingly, quit painting for some time to explore different avenues regarding photography. Note that he printed a photo of similar ballet dancer in two ways, as she was caught by camera and furthermore in switch. So he had two superb signals that he could use in his organizations.


Anders Zorn was another expert who involved the photo in more than one way. He was known for taking photographs of his models clearly, and making etchings from the photographs, most likely to more readily grasp the upsides of a scene, and later forming the etchings into oil canvases. As a matter of fact, the demonstration of his works at the Petit Palais in Paris in 2017 finished with a wall put with his high contrast photographs of his models.


Burdens of Working with Photographs


As far as I might be concerned, the greatest burden is that the camera sees all things similarly, not at all like the natural eye, which sees specifically. At the point when you take a gander at a depiction you will see that nearly everything in the field of view is in equivalent concentration. A prepared photographic artist can control the camera to see as the eye sees, where the point of convergence is in sharp concentration and the irrelevant components are in delicate concentration or out of concentration.


I will quite often utilize the photographs that are shot rapidly with little thought to piece or point of convergence. It's later in my studio that I can take a gander at the photographs and a composition will strike a chord.


Values and varieties can be impacted by camera settings and the camera's failure to catch every one of the tones there are in nature. This was a genuine issue before computerized photography, since the lights were much of the time too light and the shadows were excessively dim.


Having the option to control values, varieties, and differentiation on our PCs has made this issue to a lesser extent an issue.


Working only from photographs can some of the time kill your innovativeness. I've seen numerous painters duplicate a photograph without thought to how they could change the game plan of objects to make a seriously fascinating piece, or dependably render something that loans no worth to the picture, essentially on the grounds that it was in the photograph.


Mutilation of structure can happen contingent upon how the camera is held, and the craftsman should have the option to perceive when that happens.


Just working enough from life will give you the ability to know when that occurs.


Benefits of Working with Photograph References


Photographs permit you to catch pictures that would be difficult to catch from life like rapidly moving articles (artists and competitors), and perspectives where it would be hard to set up an easel (like a bustling eatery kitchen). With the approach of computerized photography it is presently conceivable to snap a picture of a bustling scene, like a packed commercial center, and on your PC then broaden and detach part of the picture that would make a fascinating composition. My canvases are much of the time just little pieces of the first photograph.

My most memorable fruitful work of art from a photograph (other than representations) was taken from a little piece of a photograph I took with my most memorable computerized camera of a bustling New York café. At the point when I put the photograph on my PC and focused in on various pieces of the picture I found a situation that I could somehow have missed. I referred to it as "Confidential Discussion."

Photographs can animate your creative mind and memory. In your studio, you can try different things with plan, and consolidate photographs to make a seriously fascinating composition. You can choose a point of convergence and settle on plan choices in light of your determination. You can flip photographs (as Degas did above) and make the spans of the articles (figure, creature, tree, house, vehicle, farm truck, and so on) as enormous or as little as you want it for your sythesis.

"A Decent Take," 2015, oil on material, 40 x 30 in. For this situation I needed to show the connection between the man and the fish that were trapped in the net. I went with the choice to dispose of the subsequent man and extend the water and net in the forefront.

Veer off from all that the photograph is showing you, and figure out how to take from the photograph significant and helpful data like shape, worth, motion, and size connections. (For instance, how tall was that tree contrasted with the house? Or on the other hand, how tall was that man contrasted with the lady?) And, surprisingly, then, utilize your creative liberty! Do you believe that house should be more significant? Make it greater than the encompassing masses. Is that lady not elegant enough? Push her hip out a piece aside. Would you like to make that pink house pop? Dim the shades of the shrubberies encompassing it a piece.


These are imaginative choices you can make regardless of painting from photos.
