any Cool Ideas are welcomed
Dear friends I Know this post might be a little irrelevant to chemistry (yet it is not completely irrelevant ) ,But I have to mention that I made a
sputter coater Machine (it is not totally home built though) and I need any cool Idea of yours , to make it real with my machine .
U can see the machine here :
https://www.youtube.com/watch?v=AGiX8Rh-GGI
You can also have a look at this paper ,I think it will help you to come up with cool Ideas :-)

How about a cool pair of sunglasses?
Very cool machine by the way!

Thanks :-) ,
sunglasses sound cool But I prefer some other Ideas like this one that I came up with : "tiles coated with nano layer of Cu hopping its antibacterial
properties would make these tiles a good choice for being used in hospitals ! " I figured these tiles won't be applicable cuz coated layer could be
easily removed !
So if U have better ideas I would be happy to share them with me :-)
Many thanks

I couldn't read the paper so please excuse me if these were covered
maybe not super cool but,
I'm sure that an advert in your local astronomy forum would have a lot of amateur astronomers interested if you can do multi-coating for lenses
or even better, mirror coating or re-coating for reflectors.
Amateur physicists may want dielectric coatings for home made lasers,
sputter coatings for amateur electron microscopy samples/targets
simply announcing the availability of a cheap sputtering facility would probably interest amateur scientists with requirements that we may not think
of.
Specifically for this forum I imagine platinum or other inert coatings for electrolysis electrodes, or catalytic coatings.

Just rename the file adding .pdf at the end, as example I renamed it to Materials Letters Volume 128 issue 2014.pdf, it then opens properly.

ok, that worked, thanks.
I'd be more inclined to use silver/silver oxide than copper/copper oxide
because I think that;
.silver is a better anti-microbial agent than copper
.there are some health concerns with copper particulates inhalation

I guess one of the questions is how uniform are your coatings. For optics they would need to be very uniform.

By the moment of writing this reply I don't think my coatings are good for optics , but I am working on it ! Do U have any Ideas in the field of
optics ? I'd be happy if U share them with me :-)

Unfortunately no expertise. I think the simplest method might be to keep your sputtering target in motion.
And measuring the uniformity might be a trick too.
However, I love what you have done. I agree with Sulaiman where he says there might be a large number of people interested in Pt electrodes or
catalysts.

I am trying to keep my target in motion :-) but I have to solve some engineering problems , first .
Could U explain more about "Pt electrodes or catalysts" , what type of catalysts ? or maybe you can guide me to some scientific references :-)

Sure. I am no expert an I have no need for one at the moment.
Pt is extremely usefil as an electrode because it does not react. the problem is that it is freakisly expensive. One solution is to coat a thin layer
of Pt over a conducting substrate and then you have a functional substitute. This only works if coverage is complete. Bare patches or scratches
exposing the substrate will render the ekectrode useless.
Someone else will be along to tell you the best choice for substrate.
Likewise, Pt is peobably the mist versitile metallic catalyst there is. The normal goal is to have as high a surface area as possible. I can see
sputtering a thin layer as a very practical solution. Again, someone with actual experience wiil give guidance as to geometry and substrate
requirements.

What I can think of:
-Transparent conductive layers... Although sol-gel deposition is probably a cheaper way to get it done.
-Deposition of Beryllium coatings for (near)IR mirrors.
-Dielectric Mirror/lenses/thingies .
-Deposition of catalytic layers (only ever heard of transition metal oxides). For instance TiO2 can be deposited by reactive sputtering of Ti metal in
a oxidizing atmosphere and and it has got some cool photocatalitic properties. Other works that come in mind are the Ni-Fe thin film catalysts for
water splitting and the Manganese Oxide catalysts for oxidation of organic compounds.

Dear j_sum1 , I have Ideas for Using Pd , Pt , etc .... I also tried to make a porous sample with the most possible surface area U can see it here :
but I don't think sputtering is good choice some conventional methods like electroplating works fine :-) , yet if U have deeper knowledge in this
field and know something that I am not aware of , I'd be happy if U share it with me (I mean maybe some metals cannot be electroplated and one has to
use another method ).

Again, I have no specialist knowledge of these things. But at the level I am working at, if I needed a catalyst and wasn't sure what would be an
appropriate choice then I would love to have some Pt sputtered onto a microscope slide.
Actually, that would be good for the element collection too.

- Pt/Pd catalysts from vehicle catalytic converters is able to oxidize plenty of hydrocarbon compounds as well as hydrogen (that is pretty much the
extent of my awareness on the subject).
- First surface mirrors for lasers, telescopes, and other optics. Unless it is application critical, I doubt uniform thickness will matter
significantly.
- Coating organic or other specimens so it can go into an electron microscope
- Those "aura" type quartz crystals
- Surface preparation for electroplating
If you have enough equipment, particularly atmosphere control:
- Capacitors
- Novel batteries
- Rudimentary solar cells
- Chemical vapor deposition
- Make graphene and carbon nanotubes
- Vacuum/hydrogen brazing
- Custom ICs
I don't have any experience with any of this so I can't attest to the efficacy of any of these at the small scale. I do want to build a decent chamber
one day to do all of these things, but it will be a lot of work and expense. I already have a roughing pump and I have plenty of stuff to make an ion
pump with, now all I need is the rest of it.
Oh, and the "porous" nature of that catalyst you posted is more of a 'honeycomb' where the holes go straight through rather than something like an
open cell foam. It is that way for high flow rate applications like engine exhaust.
