This document discusses various applications of chemistry in everyday life. It describes how medical implants are made using techniques like electron beam melting of titanium powder to create prosthetics. It also discusses how polymers are used in sports equipment to increase protection and performance, through materials like polycarbonate in goggles and helmets and polyurethane in balls and flooring. Finally, it mentions uses of graphene in solar cells, fabric panels in stadium construction, and auto-cleaning technologies in household gadgets.

1. CHEMISTRY
IN
EVERYDAY LIFE

2.  As a replacement or reconstruction of the
human skeleton
 However, implants have short service time
and become loose in the long run.
 Some adverse effects of the use of implants
are inflammation and bacterial infection
due to bioincompatability.
MEDICAL IMPLANTS/PROSTHESIS

3.  Uses powdered Titanium (Ti) to be
melted on the surface of the cast
under vacuum and high temperature
electron beam exposure.
 It effectively melts Ti powder without
altering its properties creating a
dimensionally accurate prosthesis.
ELECTRON BEAM MELTING
(EBM)

4.  Production of prosthesis that is
unique to one patient
 Involves titanium and zirconium
deposition to create a surface that is
porous and fibrous similar to that of
the bone to increase
biocompatability.
COMPUTER NUMERICALLY CONTROLLED
(CNC) PROCEDURES

5.  Sports equipment and facilities use materials such as
POLYMERS to increase sports efficiency and decrease
sports-related injuries.
 POLYMER – a large molecule that is made up of
repeating smaller molecules.
 POLYCARBONATE – thermoplastic; has a good thermal
resistance and highly amorphous, which allows light
transparency
- used as a protective sports equipment
such as:
goggles, helmets, sunglasses, visors
SPORTS EQUIPMENT

6. POLYURETHANE – a thermoplastic
characterized by its versatility in form; can be
made into a rigid platform or flexible coating.
- used in layering composition of balls,
in mattings used in martial arts and as flooring
materials
- used in different sports equipment
such as surfboards, rollerblades and sports
apparel.

7. GRAPHENE – an allotrope of
carbon
- has unique combination of
electrical conductivity and optical
transparency, which makes it a good
candidate for use in solar cells
ELECTRONIC DEVICES

8. FABRIC PANELS – used in London
Olympic Stadium in the 2012 Olympics,
which served as the finishing touch of
the stadium
-used as roofing insulation
in the stadium which offered moisture
resistance and structural strength
CONSTRUCTION SUPPLIES FOR BUILDINGS AND FURNITURE

9. AUTO-CLEANING – can kill bacteria
and germ through radiation and
UV light exposure
