Hi. Lets say i have a cylinder, capped at both ends. It is cut in the middle and, say a titanium foil of 15 um thickness is pressed in between the 2 halves creating 2 spaces. It is pressed fairly hard, and a soft grip, "perfect" seal is created in someway but not right at the inside of the...
I have a friend who was in a car accident causing full and permanent blindness. I've been looking to help him solve some of the issues he is running into. One of them is that he is tall, about 6'2" and the optimal length of a White Cane for moving quickly is 4 inches shorter than your height...
Industry standard right now is a copper alloy (usually an aluminum bronze) inner liner to promote heat transfer to the coolant channels and the walls of the channels and outer liner are usually made of an INCONEL alloy, usually either 625 or 718.
But INCONEL is VERY expensive and heavy. The...
I have about 40kg Titanium oxide. At least that is what I was told it is. There is a stretch of beach that is covered several cm with this black material. I would like to melt it and make... something with it.
Any ideas how I can melt it at home, as this seems the first step and much more...

Hello everyone, I am working with a writer on a book that is bordering on science fiction but set in modern day Earth.
Here is the issue. There is a titanium case with high-carbon steel pins in the hinges. (Think of a sophisticated military weapons style of container.) The characters in the...
I wanted to know the finer details of synthesis of Titanium Oxide Nano-particles coated in Graphene Oxide, what exactly does creation of these nano-particles entail?
Hello. I want to coat titanium metal, more preciselly grade 5 alloy with thick titanium coating. Can coating be done using electroplating method with chrome salt? I guess titanium surface will have to be somehow well prepared, removed from oxides so that chrome won't just peel off from titanium.
Homework Statement
A titanium disk (with ##E=107 ~GPa##, Poisson's ratio, ##v=0.34##) precisely ##l_0=8~mm## thick by ##d_0=30~mm## diameter is used as a cover plate in a mechanical loading device. If a ##P=20~kN## load is applied to the disk, calculate the resulting dimensions, ##l_{01}## and...
Hi all,
I sputtered titanium (10 nm) - gold (~ 100 nm) films at room temperature on
oxidized silicon substrates. The titanium acts as an adhesion promoter between the SiO2
and the gold film.
My Question:
What is the adhesion mechanism between the titanium and gold film at room temperature...
Hello fellow scientists.I am currently doing a project that requires me to make a stock solution of titanium dioxide which i will use to make different concentrations and measure absorbance and then plot a calibration curve which will be used to determine the concentration of Ti02 in an unknown...
Titanium's melting point is between 1,600 and 1,700 degrees Celsius. What sort of equipment would I require to melt it? Is there something I can buy and install in my own little area that could melt titanium? Would I be able to power it or can this only be pulled off in a factory?
Thanks.
What are the preferred, low-cost options for cutting & joining Titanium?
I'll explain my use case: There's a fabricator with long experience working with Carbon Steel & Stainless Steel but now we want to assign him a Heat Exchanger project where the tubesheet & tubes must be Titanium. He has...
What would be the possible options to join Titanium Heat Exchanger tubes to a PTFE / Teflon tubesheet? These are 38 mm tubes, 2 mm thick. 6 m total length. Seamless tubes.
Is this a reasonable design decision? Full titanium tubesheet would be excessively expensive & isn't needed since only...
I'm currently looking for an efficient water splitting water catalyst for my Chemistry project. Titanium Dioxide is the popular one, as it's cheap and abundant.
However, TiO2 is only most efficient when shined by UV light, not visible light ---> Which accounts for more than half of solar...
Hi all,
Does anybody have any experience with titanium and graphite in terms of friction and wear over time in a relatively high temperature environment?
I realize that galvanic corrosion shouldn't be too much of an issue, but I was wondering from a sort of tribological point of view.
Hope this...
Hello all,
Does anyone knows what is the exact energy gap of Titanium Nitride (TiN) film? Is it indirect band gap or direct band gap?
From literatures, I've found that the band gap for TiN is around 3.35-3.45eV. . May someone could suggest the specific band gap for TiN?
Thanks.
Hello I am trying to solve this integral 25-9x^2-25y^2/9 dydx integrating from 0 to sqrt(9-9x^2/25) and the limits of the second integration are 0 to 5. I can find tutorials on how to find the definite double integral of a single variable, but not for two variables. Any clues?
edit: so far...
I have a Ti-89 titanium and its not allowing me to enter text into an equation without writing over the equation. Is there a way I can change this? It seems like I could do this before, I thought maybe I accidentally pressed something without realizing it.
I was working with a much longer equation and receiving a result I didn't expect, and finally narrowed it down to the following section:
2(-2^3)-3(-2^2)
2(-2^3) is correctly calculated as -16 independently, and 3(-2^2) is correctly calculated as 12 (again, independently) for a difference...

Hi.
So, for the first time my younger sibling will need a graphing calculator for their classes so I'm giving them my TI-84 Plus and getting myself a new, better one. Right now I'm a Junior in high school taking ap-chemistry, ap-physics and ap-calculus AB. Next year I'll be taking calc BC (my...
I am not sure what I did, but a setting changed on my Ti-89 Titanium. I used to be able to go back to my input line and add new characters like a parenthesis or a missing number. This is one of the big advantages to a ti-89, however, somehow, When I go to insert new characters, they erase the...
There is something wrong with my TI-89 Titanium. When I enter factor(x^2-5x=6), it displays the answer as 6.17481 E12/ (2)^11 * (5)^13.
I've checked all the mode settings and they seem to be same as the initial settings. Any idea what could be wrong?
Can someone guide me toward using my TI-89 Titanium calculator for sequences?
I would like to be able to PUT IN a sequence of numbers and have it GIVE ME the formula. Not vice versa please. Thanks.

I recently bought a TI-89 Titanium and I want to put some of the programs on ticalc.org onto it. I downloaded the program and dragged it into the TI connect program and it transferred but didn't show up on my apps list. I tried it with other programs to and got the same result what am I doing wrong?
EDIT: I found the solution, it can be done using the TwoVar() function on the TI-89 and it gives you a whole lot more than just the expected value. thanks anyways

I use TI-89 Titanium normally.
It was not even a month since I changed my batteries.
One day I pressed on but did not turn on.
I tried out other batteries and found out that batteries were not the matter of problem.
What's wrong?
What should I do?
