(B) At the level of
molecules:
The nucleus of an atom is
surrounded by orbits where electrons are revolving around
the nucleus. Electrons responsible for reactions are
revolving in a band called valence band.
There is a band outside the valence band referred to as the
conduction band.
In TiO2, as it is a compound consisting of different atoms,
the valence and conduction bands are complicated, but the
principles involved are the same. When the energy of light
is applied externally electrons in the valence band are
excited and rise to the conduction band. Then positive holes
are formed and left behind the rising electrons in the
valence band. At this time the MVX is photo excited. The
resulting positive holes show sufficient oxidative power.
As MVX is TiO2 dissolved in water, water is oxidized by
positive holes forming hydroxyl radicals (OH-) which has a
strong oxidative decomposing power.
Also, Oxygen of the air is reduced by the rising electrons
resulting in the production of super oxide anions (O2-)
which is capable of attacking bacteria. Both super oxide
anion and hydroxyl radicals are the main reactants
responsible for the functions of MVX.


Functions of Sterilization " MVX "
1) Antibacterial & Detoxification Action
MVX has excellent
bactericidal effects even without ultra violet rays, furthermore,
when U.V. rays are irradiated,
MVX also can decompose the remnants of dead bacteria.

MVX Antiviral effect avian flu
MVX has strong effect on killing almost
all kinds of viruses including SARS & Avian flu ( H5N1
).
Effect against
influenza viruses
The amount of antibodies in normal
blood uninfected by viruses is approximately 2 µgm/ml which was
defined as HA value = 2, when blood is infected by a virus, hem
agglutinin occurs, causing antibodies to increase in number. The HA
value of 1280 for the untreated samples means that the virus caused heamgglutination and increased the number of antibodies by 640
times.
-On the other hand, the samples treated with the MVX inhibited
heamagglutination by destroying the virus.

MVX Anti Fungal Effect
MVX has a good antifungal effect on
different types of fungi e.g. Aspergillums Niger & Candida albicans
reducing their concentration by 34.65% after 2 hours of contact.
MVX Deodorizing Effect
MVX produces a noticeable difference in deodorizing character. The
smell of very high concentrations of ammonia gases (40 ppm) in a 2
hour period will dissipate up to 99.6%.
MVX Anti Dirt Effect
MVX gives relative charges to the surface it's
coated with when exposed to every source of light, also fine dust
carries negative charges so, both the surface & the dust carry
negative charge and they repel with each other so, surface clear
without accumulation of dust.
MVX Hydrophilic effect
M character due to the presence of (OH-) radicals, with
very high
affinity to water, and self cleaning effect is generated
by waterfall.
THE ACTIVITY OF " MVX "
MVX produces long lasting
disinfection remains for 5 years and certainly we have a very good
visible proof for the validity of MVX functions as a sterilizing
material for surfaces. As we have known that the mechanism of action
of MVX depends on the presence of (OH-) & (O2-) radicals.
So, we have 2 tests ensuring the presence of
these two radicals.
(1) Silver nitrate
: is a colorless solution turns black in color due to the presence
of O2- radicals .
(2) Methelene blue : is a blue colored
liquid when oxidized, its color fades within 30 minutes due to the
presence of (OH-) radicals.

1.What is titanium dioxide? What is a
photo catalyst ?
Titanium dioxide (TiO2) is an anti-microbial
metal created by a process which crystallizes titanic iron ore
into a nano liquid form. When exposed to normal light, TiO2 becomes
a photo catalyst
oxidizer (PCO) as well which creates hydroxyl radicals and
superoxide ions which are two times stronger disinfectants than
chlorine and 1.5 times stronger a disinfectant than ozone. TiO2 is
safe and widely used in many household products such as toothpaste,
food, and teeth whitening solutions
The advent of nanotechnology, in other words making tiny particles
out of metals that can penetrate most surfaces,
has lead to several Japanese patents utilizing this nano TiO-2 photo
catalytic solution which has many wide ranging applications and has
experienced years of successful use in the Japanese marketplace
For instance the government uses this solution in some public
bathrooms to keep them smelling fresh and more importantly
maintenance free. TiO2 coatings are applied to some highway guard
rails to keep them looking new amidst constant bombardment from
hydrocarbons and VOC's from vehicle exhaust
The outside of some Japanese high rises are treated with TiO2
solution to make the glass and metal maintenance free, no more need
to clean the windows, they resist water and grime. TiO2 coatings are
also widely used in the healthcare, food, janitorial, auto, and
construction business. Many homeowners treat their mini-blinds,
windows, furniture, bathrooms, showers, carpets, flooring, etc with
similar TiO2 solutions to reap the benefits of VOC free, clean,
fresh indoor air on top of the huge benefit of maintenance free
surfaces. When microorganisms, smog, viruses, VOC, or any organic
material comes in contact with the TiO2 treated surface, it also
becomes oxidized. Even fabrics treated with this revolutionary
substance will not retain odors. Car interiors treated with Nano
TiO2, even when submitted to second hand smoke from several people
for prolonged periods of time, will not retain any tobacco
odor.
2. Are TiO2 coating harmless to humans?
Is it harmless to pets ?
Nano TiO2 liquid is completely harmless to
human bodies and is actually used widely as a food additive. View
test results) Nano TiO2 liquid is made with a patented binding
process that makes it possible for(
this liquid to penetrate and form a permanent bond with surfaces. It
is not for human consumption in this nano liquid form of course.
However, after it dries to form a film on a substance, it becomes
one with the surface. Nano TiO2 liquid should not be applied
directly on pets or animals. It can and should be used however to
keep pet bedding from retaining odors
3. After applied, does it produce any
odor ?
No, it does not have any odor. If applied to
surfaces with for instance tobacco odors, those odors will go
away.
4. Does this Nano TiO2 liquid have a
shelf life ?
Basically, there is no shelf life . This
solution should be stored in a dark, cool environment long term
however.
5. How is this Nano TiO2 liquid applied
?
It can be brushed or sprayed onto surfaces.
When applied to fabrics via spray, a brush should be used
to work the solution into the fabric.
6. After it is applied, how long does it
last ?
The Titanium crystals in Nano TiO2 liquid
form bonds that are semi-permanent. In case of some
materials that may undergo a physical peeling off by some force
(such as carpets, mats, and clothing), it
is recommended to reapply the solution every 3 years. Generally
speaking TiO-2 PCO Solution has a
service life of 5-10 years or even longer on some surfaces that do
not have a lot of contact. Basically,
our solution will out-live many materials such as curtains, carpets,
shingles, etc.
7. Does Nano TiO2 liquid cause any
fabric discoloration or any streaking effects on solid surfaces?
Nano TiO2 liquid can be applied to fabrics,
curtains, carpets, woods, tiles, ceramics, glass, even metal
and painted surfaces. If the surface is exposed to direct sunlight,
do not apply to black or very dark
colored surfaces as the oxidation process can remove some pigments
from surfaces. Indoor light is not
strong enough to cause this oxidative reaction on fabrics and
surfaces however. When spraying any
surface with Nano TiO2 liquid, it is always advisable to spray a
small area first (test area) then allow to
dry to make sure the solution does not react with the surface. Do
not apply Nano TiO2 liquid to leather,
silk, or fine garments. Once you are confident that the fabric or
material can safely be treated, spray the
surface until it is completely moistened then brush in with any type
of brush to work the Nano TiO2 liquid
into the fabric. If applied to non fabric surfaces (plastic, metal,
glass, etc) the initial coat will leave a fine
milky residue. Allow the area to completely dry then wait several
hours and wipe the area with a damp
cloth.
8. How long does it take it to dry?
A film will have formed once the liquid has
completely disappeared. The time needed for this to occur
(evaporation time) will be varies with temperature, wind, and film
thickness. Generally speaking, it only
takes 5-15 minutes to dry on solid surfaces and around 1 hour or
longer to dry on fabrics. Use a blow
dryer to speed up the drying process as well as aid with the bonding
process.
9. How long does
Nano TiO2 liquid have be exposed to light before it released
oxidizers into the air to
get rid of indoor air pollution?
Studies have shown that this Nano TiO2 liquid
will actively begin creating hydroxyl radicals and
superoxide ions when exposed to ultraviolet rays in the sub 400nm
range. Regular house lights will even
activate the TiO2's disinfectant effect to a minor extent,
especially florescent type lamps such as those
found in many kitchens. However it's direct sunlight, UV radiation,
and black lights (UVA) that create the
most oxidizers Hydroxyl radicals and superoxide ions do not give off
a strong beech like ozone does but
they do aggressively go after odors and air pollution better than
ozone or chlorine.
10. Does Nano TiO2 liquid remove odors
from the air? From fabrics?
The surface area of titanium dioxide per gram is
about 300um (equivalent to that of activated charcoal).
When exposed to light, Nano TiO2 liquid will create -OH (hydroxyl
radical) and O- (super oxide ions)
which will decompose the substances which are creating the odor. The
principal difference between
titanium dioxide and other odor adsorbing substances including
activated carbons is that titanium
dioxide will repeats this disinfectant function semi-permanently vs.
activated carbon and other adsorbing
substances such as Zeolite which lose their effectiveness once
they're full of absorbed substances.
11.How does Nano TiO2 liquid prevent and
remove contamination from surfaces?
The reason why airborne contaminants such as
second hand smoke, car exhaust, molds, VOC's,
viruses, bacteria, etc cannot adhere to surfaces treated with Nano
TiO2 liquid is that they become
oxidized by the photo-catalytic oxidation and float away as harmless
substances.
12. Why does Nano TiO2 liquid have a
sterilizing and anti-microbial effect?
The old standard for killing airborne
microorganisms has been strong UVC radiation. (Over 20,000
microwatt's of UVGI per second) UVC germicidal radiation kills
microbes by destroying their DNA.
However, some microorganism, anthrax most notably, have very strong
DNA coatings and can resist
even 30,000 microwatt's of UVGI. Our Nano TiO2 liquid works in a
different way. Titanium dioxide
decomposes and destroys the cell membrane, not the DNA. Most
microbes are single celled organisms
so they die quickly when any part of them comes in contact with a
coated surface. Accordingly, titanium
dioxide even kills MRSA (Staphylococcus Aureus) a major cause of
hospital infections. Our TiO2
solution has also been proven to even kill other types of microbes
that are not even killed by antibiotics!
(TiO2 is not selective on types of microorganism it kills, it kills
them all). For this reason, Japanese
hospitals have shown great anti-bacterial results with our
particular patented brand of TiO2 solution. In
addition, our Nano TiO2 liquid decomposes toxins that are discharged
when microbes die (Verotoxins,
Enterotoxins), rendering them into harmless vapors.
13. Exactly what types of odors will
Nano TiO2 liquid eliminate?
It will remove virtually all and any type of
odor from surfaces as treated surfaces become resistant to
microorganisms, mold, bacteria, viruses, smoke, odors, etc. It
removes odors from the air when a treated
surface is exposed to certain light thus creating the photo
catalytic oxidative superoxide ion and hydroxyl
effect.
14. Does it work in cold environments
such as freezers?
Yes. Microbes that come in contact with a
treated surface will cease to exist.
15. Does Nano TiO2 liquid get rid of
cigarette odors from tar and nicotine that have penetrated surfaces?
Yes. If a second hand smoke contaminated surface
(second hand smoke is known to have over 400
known cancer causing chemicals) is treated with TiO2 PCO Solution,
the odor will soon disappear.
However, the discoloration caused by second hand smoke does not
disappear. It is therefore advisable
to first wash smoke contaminated surfaces that show discoloration
before treatment.
16. How does the intensity of light
effect the ability of this Nano TiO2 liquid to create friendly
oxidizers which purify the air?
As a characteristic of titanium dioxide, it
starts to produce friendly oxidizer en mass when exposed to
ultraviolet rays of 400nm range or lower. It is more affected by the
intensity of the ultraviolet rays rather
than the intensity of light itself per se. However, any air
pollution, VOC, or odor that comes in contact
with a surface treated with Nano TiO2 liquid will become oxidized.
17. What are some of the more popular
applications for Nano TiO2 liquid?
Bathrooms, floor tiles, sinks, showers, car
interiors, to remove and prevent tobacco odors, kitchen
counters, furniture and carpets (especially if you have pets),
curtains, mini-blinds, windows exposed to
light, ceiling fans, car rims, white outdoor furniture, house
gutters (keep them mold free), concrete or
brick that you want to keep mold free, the list goes on and on.
18. Can Nano TiO2 be applied to carpets?
Yes, and with great results! Carpets treated
with Nano TiO2 will resist not only odors and grime but also
pests such as fleas. Carpets will last much longer as well. For this
reason, carpets and fabrics in trains
and pubic transportation are now being treated with Nano TiO2 in
Japan with great results.
