Aim To familiarize oneself with some more common instances of corrosion. Reagents Hydrochloric acid 0.1 M; sulphuric acid 0.1 M; zinc and aluminium granules; copper wire; solution of copper(II) sulphate; solution of copper(II) chloride; solution of iron(II) sulphate; solution of potassium hexacyanoferrate(III); zinc-plated iron sheet; tin-plated iron sheet; iron paper clips; solid NaCl; urotropin. Equipment Test tubes, small beaker (50 cm3), centrifuge tube. Experiments 1. Making of a galvanic pair 1.1. Place a zinc granule on the bottom of the centrifuge tube and pour solution of hydrochloric acid on top. Write down the equation of reaction which occurs. Which compound is the oxidant, which is the reductant? Zn+2 HCl ZnCl 2 + H 2 -¿ H 2 Oxidant is H: +¿+2 e ¿ 2 H¿ 2+ ¿ ¿

It included: Platelet-rich plasma (PRP) PRP is an emerging treatment mainly used with elite athletes. It gained national attention in 2009 when used successfully to treat two Pittsburgh Steelers just weeks prior to their Super Bowl victory. PRP contains the plasma portion of your blood with concentrated platelets. Platelets are packed with growth and healing factors and are part of the body's normal tissue repair system. The PRP is prepared using a special centrifuge after whole blood is drawn from your arm, similar to getting blood drawn for lab work. Making platelet-rich plasma. PRP formed the base to which the following were added: Stem cell factor (SCF), flown in from Israel, which assists in blood cell production. Bone morphogenic protein 7 (BMP-7), which helps adult stem cells (mesenchymal) develop into bone and cartilage. In retrospect, I believe this to be the most dangerous
