Bir tasarım yaparken malzeme seçiminde kullandığımız chartlardan sadece birisi. Bunun gibi 20 tane daha var. Eğer orgazma ulaştıracaksa detay vereyim, orada yazan tüm malzemelerin tüm türlerini, mikro ve makro yapılarını ve bu yapıların kazandırdığı kimyasal ve mekanik özelliklerini, grafiklerini, grafikleri etkileyen faktörleri ve üretim yöntemlerini, bu grafiklerde özellikleri tanımlanmayan semiconductor malzemeleri ve bu malzemelerde kullandığımız katı hal fiziğini gereken tüm formülleriyle biliyoruz.

Project idea

High school students are not often exposed to the field of biomaterials. We have developed and implemented several interactive biomaterials activities for high school students. The activities performed at two events (Vanderbilt Summer Academy and Biomaterials Day) will be described during this presentation. 11th and 12th grade students at the Vanderbilt Summer Academy completed a biomaterials design project requiring them to create polyurethane scaffolds that could be used to deliver a drug and provide mechanical support for a given tissue. Students participated in hands-on activities that involved making polyurethane scaffolds, measuring release kinetics and determining release mechanism of dye from various scaffolds, and performing tensile tests to create stress-strain curves and determine mechanical properties of the scaffolds. Students worked on the design project for a total of ~20 h over the course of three days. High school students attending Biomaterials Day participated in a networking lunch, poster session, and hands-on activities. The activities lasted half an hour each and included extracting your own DNA, measuring the strength and Young's modulus of biomaterial scaffolds, and making your own lab-on-a-chip.

New material is expected to convert 15 to 20% of waste heat into useful electricity - nearly 30% more efficient than modern-day technologies

Bubbles are dangerous and should be handled with caution! New research involving the Lotus leaf helps prevent bubble formations. Take that, bubbles!

Everyone knows when water is hot when you are boiling water, you can tell from the water bubbling at the surface -this phenomena is when the water is bouncing off of a cushion of air or the Leidenfrost regime- or if you are inexperienced in this you can tell by sticking your finger in the water which is usually followed by you immediately regretting that decision.

Now scientists have made a material that prevents the bubble formation when the liquid begins to boil. This is achieved through using a nanomaterial that is extremely hydrophobic, meaning "water hating". The nano-material was developed earlier in April from inspiration from the Lotus leafs natural water repellent properties and is sprayable onto surfaces. The water repellent spray turns water droplets on the surface into almost perfect spheres as a result of the water trying to minimize contact with the hydrophobic surface.

This new nanomaterial maximizes the amount of surfaces bumps, increasing the surface area in which the hydrophobic regions are exposed, meaning the water will have less area to interact with, which is why they form into spheres. Because of this the water completely avoids going into the bubble phase when boiling.

Some applications for this hydrophobic coating are; anti-fog purposes, preventing bubbles beneath boats which cause damage to the surface when they explode (kind of like how the pistol shrimp defends itself) and even reducing drag on the ship. This may be useful in nuclear power plants as well, by preventing explosions. Explosions in a nuclear power plant are definitely a bad thing, so that's good.

Fizik Araştırma Konusu

Research and study topics on properties of special materials involved in physics (i.e. physical quantities, properties) and the relationships about the mechanics of materials such as tensile, strength, stress etc. support your ideas with with well-known physical examples/applications.

Hoca bu ödevi verdi ancak biz şimdiye kadar malzemeye dair neredeyse hiçbir şey öğrenmedik. Yani benim malzeme bilgim diğer malzemeciler gibi sıfır.

Ayrıca bu ödevi yapmak için deney yapmak gerekiyor diye düşünüyorum ve okulumda laboratuvar yok, olsa bile deney araçlarını kullanmasını bilmiyorum.

Keşke 100 soru verseydi de çözmemizi isteseydi.
