Rare earth magnets

== Description ==
A general name for highly magnetic films made from rare earth elements. The strength of rare earth magnets exceeds those of ferrite magnets by approximately 10-fold. Additionally, they are lightweight, as thin as 0.06 inches, and are resistant to corrosion and demagnetization. Rare earth magnets are divided into two categories, that is, the SmCo-type (samarium-cobalt) rare earth magnets and the NdFeB-type (neodymium-iron-boron) magnets (also called Nd magnets). More than 98% of the rare earth magnets are the Nd magnets
== Risks ==
* Rare earth magnets are extremely strong. Handle with caution as they can fly together and pinch fingers and art (AIC Wiki).
* Rare earth magnets are brittle and subject to corrosion so they are usually plated or coated.

Rathgen-Forschungslabor

= Rathgen-Forschungslabor (Rathgen Research Laboratory) =
The Rathgen-Forschungslabor is believed to be the oldest museum’s laboratory in the world. It was founded in 1888 as the Chemical Laboratory of the Königliche Museen zu Berlin and was later renamed in honor of its first director Friedrich Rathgen, a chemist who was specialized in the conservation and analysis of historical objects.
As the scientific arm of the Staatliche Museen zu Berlin, the Rathgen-Forschungslabor provides support and advice on issues related to conservation, art technology and archaeometry. It not only offers its services to the museums in Berlin but also to institutions and organisations across the globe. The laboratory investigates museum objects and materials of all kinds, and conducts research on the preservation of historical monuments and archeological sites.

== Description ==
Any tall, slender stem from climbing palms of the genera Calamus, Plectomia, Desmoncus, or Daemonorops native to tropical Asia. Rattan stems are long, tough, flexible and durable. They are split lengthwise and woven shiny side up to make the backs and seats of chairs, umbrella handles, whips, baskets and baby carriage bodies. Rattan caning became popular about 1660 in England and was widely used during the Victorian period. Rattan has also been used for papermaking in the far East.

Reactive dye

== Description ==
A water-soluble synthetic dye that reacts with molecular groups in a fiber to form a covalent bond. For example, a fiber-reactive dye with an azo group can bind to the hydroxyl groups in cellulose. Reactive dyes were first discovered in 1954 by Rattee and Stephens at ICI and they were marketed as Procion dyes in 1956. Since then, over one hundred varieties have been patented. Fiber reactive dyes have bright colors that are both lightfast and washfast. They are most commonly used on Cellulose fibers but also react with the hydroxyl or amino groups found in wool, silk, Nylon, Acrylic, and Acetate fibers.
== Synonyms and Related Terms ==
fiber reactive dyes; fiber-reactive dyes; fibre-reactive dyes (Br.); colorante reactivo (Esp.); corante reactivo (Port.) 
Examples include: Procion [ICI]; Cibacron [Ciba-Geigy]; Drimarene

Recycling

==Description== 
The process of converting waste materials into new materials and objects. Recycling depends on a materials ability to first, be separated from other materials and secondly, to reacquire properties that make it into a useful product. In our society of high water, recycling is a key component for waste reduction. The types of recyclable materials include many kinds of glass, paper, cardboard, metal, plastic, tires, textiles, batteries, and electronics. In addition, composting is the reuse of biodegradable waste from foods and plants.
Some common recycling types are listed below:
Item; Plastic Designation Number 	Yes for recycle bin 	No for recycle bin 	Comments 	Recycled products produced
Paper/cardboard 	Newspaper, magazine, mail (even with plastic windows), food containers, boxes 	Gift wrap with shiny surfaces; food particles (spatula clean food containers to recycle) 	 	More paper and cardboard
Polyethylene terephthalate (PET); #1 	Food and beverage containers 	Remove plastic labels (not recyclable) and caps (recyclable but different material) 	 	New bottles, clothing like polar fleece, carpets and sleeping bags
High density polyethylene (HDPE); #2 	Bottles for milk, laundry detergent, household cleaners; dairy tubs and cartons 	 	 	Pipes, floor tiles, plastic sheeting; crates
Polyvinyl chloride (PVC); #3 	None 	Some cooking oil and shampoo bottles, cling film; shower curtains; structural boards and boxes, vinyl fabrics	Some can be shredded/melted and reformed (downcycled); As waste, they can release toxic materials; PVC is on many DO NOT USE lists	Plastic wood, insulation; cables
Low density polyethylene (LDPE); #4 	None 	Grocery bags, bread bags, squeeze containers (toothpaste); cellophane wrap used in packaging 	In-store recycle locations; can be shredded/melted and reformed 	Envelopes, floor tiles, trash can liners; plastic wood
Polypropylene (PP); #5 	Medicine containers, bottle caps; ketchup bottles; some food bags like for cereal	 	 	brooms, brushes, plastic trays, ice scrapers
Polystyrene (PS); #6 	None (banned for use in some cities) 	Bubble wrap, Styrofoam, packing peanuts; hot beverage cups 	Can be shredded/melted and reformed (downcycled); non-biodegradable but falls apart with age and spreads throughout ecosystems 	Plastic wood, insulation, crown molding
Other; #7; includes Acrylic, nylon, polycarbonate,	 	 	 	
Glass 	Food and beverage containers 	Metal caps 	 	More glass containers
Aluminum 	Cans, foil 	Do not crush cans 	 	More aluminum containers
