Module 23

Projekportefeulje

Opdrag 1a:

LU/AS 2.2

Soek voorbeelde van verskillende soorte houers in tydskrifte en knip dit uit. Sommige voorbeelde van houers word slegs vir ‘n SPESIFIEKE DOEL gebruik, soos ‘n eierhouer, ‘n melkbottel en ‘n gereedskaphouer. Ander houers is vir ALGEMENE GEBRUIK, soos ‘n mandjie of ‘n tas. Plak ten minste vyf voorbeelde van elke tipe houer in die raampies en voltooi die vrae oor elke prentjie.

Vrae:

1. Vir wie/waarvoor word dit gebruik?

2. Waarvan is dit gemaak?

3. Is dit relatief duur of goedkoop?

4. Kan dit herhaaldelik gebruik word of slegs een keer?

5. Is dit voordelig /bio-afbreekbaar vir die omgewing of vergaan dit moeilik en besoedel die omgewing?

6. Is dit duursaam of kan dit maklik breek?

  • houers vir spesifieke doel

1.

2.

4.

5.

  • Houers vir algemene gebruik

Opdrag 1b:

Om ‘n lys te maak van verskillende soorte houers wat voordelig is vir mense. verduidelik.

LU/AS 3.2

Opdrag 1c:

Om ‘n lys te maak van verskillende soorte houers wat nadelig is vir die omgewing. verduidelik.

LU/AS 3.2

Ontwerpvoorstel

Ontwerp en maak ‘n juwele-kissie wat jy graag sal wil hou.

Opdrag 2:

Om die spesifikasies van jou produk neer te skryf

LU/AS 1.6

Skryf die spesifikasies van jou produk deur die volgende vrae te beantwoord:

1. Wat sal dit bevat? / Waarvoor sal dit gemaak word?

2. Watter vorm sal dit hê?

3. Hoe sal dit lyk?

4. Hoe sal die deksel aan die kassie vasgemaak word?

5. Sal dit elke dag gebruik word of slegs vir spesiale geleenthede?

6. Hoe sal die deksel oop en toemaak (sluitmeganisme)?

7. Watter indruk moet die houer maak? (Opwindend, eenvoudig, mooi, elegant, funksioneel)

8. Wat is die mees geskikte materiaal om vir ‘n luukse houer te gebruik?

  • Tipe papier: glad, blink, dik, dun, gekleurd.
  • Watter soort karton sal jy gebruik vir die versterking aan die binnekant?
  • Watter tipe hout sal jy gebruik vir die versterking en versiering aan die buitekant?
  • Watter tipe kledingstof wil jy gebruik om die binnekant mooi af te rond? (satyn, sy, fluweel, vilt).

MAAK/ VERVAARDIGING

Opdrag 3:

Om ‘n kissie te maak

LU/AS 1.9

Instruksies vir die maak van die kissie.

  1. Plaas die net, die deurslagpapier en die karton in dié volgorde onder mekaar.
  2. Gebruik ‘n potlood en ‘n liniaal en trek die 2D-vorm op die karton oor. Trek eers die aaneenlopende lyne en dan die stippellyne af. Loer of alles oorgetrek is en maak seker dat dit nie skuif nie.
  • Wat is die doel van die aaneenlopende lyne?
  • Wat is die doel van die strepieslyne?
  • Knip die 2D-vorm uit op die aaneenlopende lyne met ‘n skêr.
  • Keep die stippellyne op die kant waar die deurslagpapiermerke is met ‘n els / skêr en ‘n liniaal. Doen dit op ‘n geskikte oppervlakte. Oefen eers vooraf sodat jy nie die kepe te diep maak nie.
  • Vou op die strepieslyne met ‘n liniaal.
  • Gom die flappe met lym en vorm die 3D-houer. Hou stewig in posisie vas sodat die houer deeglik droog word. (Moenie te veel gom gebruik nie. Die oppervlak moet net taai wees.)

Opdrag 4a:

Om te beplan vir die maak van die produk

LU/AS 1.9

Voltooi die volgende tabel deur die instruksies deur te lees en al die gereedskap, materiale en aksies onder die korrekte kolom neer te skryf.

what is fullerene does it is used to make bukky balls
Devang Reply
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

what is the Synthesis, properties,and applications of carbon nano chemistry
Abhijith Reply
Mostly, they use nano carbon for electronics and for materials to be strengthened.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
s. Reply
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.

Do you know which machine is used to that process?

what is the application of nanotechnology?
Stotaw
In this morden time nanotechnology used in many field . 1-Electronics-manufacturad IC ,RAM,MRAM,solar panel etc 2-Helth and Medical-Nanomedicine,Drug Dilivery for cancer treatment etc 3- Atomobile -MEMS, Coating on car etc. and may other field for details you can check at Google
Azam
anybody can imagine what will be happen after 100 years from now in nano tech world
Prasenjit
after 100 year this will be not nanotechnology maybe this technology name will be change . maybe aftet 100 year . we work on electron lable practically about its properties and behaviour by the different instruments
Azam
name doesn't matter , whatever it will be change... I'm taking about effect on circumstances of the microscopic world
Prasenjit
how hard could it be to apply nanotechnology against viral infections such HIV or Ebola?
Damian
silver nanoparticles could handle the job?
Damian
not now but maybe in future only AgNP maybe any other nanomaterials
Azam
Hello
Uday
I'm interested in Nanotube
Uday
this technology will not going on for the long time , so I'm thinking about femtotechnology 10^-15
