Ok, just commenting on the colored oxidation question.The "colored" films form at less than one micron thickness. They indicate the VERY early stages of oxidation.
I hope your well on your way to a full recovery! That is some scary stuff alright! Yes, the only living force of nature that can potentially take out the most advanced force of nature the planet has ever known, is naturally the simplest one. It's an arms race between mind and mutation. Still I see things every now and then like the following, that I find rather cool and encouraging.
Scientists Hit Antibiotic Pay Dirt Growing Finicky Bacteria In Lab : Shots - Health News : NPR
I absolutely agree. Even failures are valuable. They teach us what doesn't work for whatever we were trying to accomplish..but
I had a professor in a lab course who said all failures need to be examined carefully because they illuminate facts and all facts are good for something. He said our job was to find out what our failures were good for and work like hell to take advantage of them.
I guess these guys were trying to make bacteria live and when they didn't live they were smart enough to find out why ...and they "invented" a new antibiotic.??
A remarkable development I hadn't fully appreciated from blips on "growing bacteria in soil" of other accounts. Excellent article. Thank you.
Good luck.![]()
I have to disagree with the idea that nicotine is not addictive. I think at this point it is well accepted in the medical community that nicotine "lights up" specific nicotine receptors in the brain and that it also "lights up" reward pathways that are really hard to extinguish. Because of the way brain chemistry self-regulates, using nicotine changes brain chemistry and it takes a good while for it to adjust to cessation of nicotine use. Nicotine, from a neurological standpoint, can be more addictive than *******. There are other really biologically active alkaloids in tobacco that are also addictive, but nicotine is the big one. BT did enhance the natural nicotine content of tobacco (along with the other addictive alkaloids) but it's the nicotine they were after to feed addiction.
Luckily, and I think this is where some confusion may stem from in the public, nicotine is not particularly harmful in small quantities. Nicotine does produce an insulin response and long term nicotine use is linked to type II diabetes. Most sweets have a similar effect so unless the govt plans to ban sweet foods and certain fruits, no show stopper here. Otoh, nicotine is being studied as a treatment to delay Parkinson's and other disease of the brain. It might actually be good for some of us. One issue hampering some of this research is the link in the public's mind between nicotine use and smoking tobacco. Two very different things but the media keeps demonizing nicotine.
Coffee is also an addictive alkaloid (most people get headaches if they stop drinking a regular dose of morning coffee). I'd bet if we smoked coffee instead of drank it, it would end up being a much stronger addiction than it is (the faster a delivery method gets to the brain, the more addictive the substance tends to be).
I have not done any studies on my own to reach the above conclusions but I've just read the results of studies I think are valid. Just throwing out a counterpoint.
That was pretty much in line with my own personal experience, and like I said they have research that suggests that some people's brains are more receptive to nicotine and these people are way more addicted to it than others. I know that I personally can't resist the urge to smoke or vape anymore than I can resist the urge to use the bathroom after drinking a 6 pack of beer (which I don't do very often) One thing I have noticed since I started vaping is that the nicotine gums actually work for me now. When I was smoking, I could chew five pieces of it at once and it wouldn't help much. Yet I have seen plenty of people quit cold turkey like it was nothing.
Gene Variant May Affect Nicotine Receptors in Lung, Brain or Both
Orion,
Poor wicking - for the last few months I have been building 4.5mm ID coils. Most Attys have trouble if the coil it too long but 4.5 mm ID fits all of my RTAs. IMHO 4.5 mm wicks are the gift that just keeps giving. I have never had one not keep up with my use. I run 8 turns 26 Ga Ni200 which comes out about 0.12 ohms.
It really works I am also trying it with Ti that Tony sent me only I forgot that Ti is higher in resistance so with the 28 or 30 Ga he sent me and 8 turns it comes out about 0.7 ohms but still works fine. I just don't have a clue what temperature I am running at. it kind of idles around 235F and I set the TP at 250. I really don't know what I SHOULD set the TP at but it is working fine (???).
I think that some people are more susceptible to nicotine addition than others. The same is true of many substances, alcohol, chocolate, soda and a long list of them. Even certain "behaviors" are addicting to some people which would lead one to think that they are more susceptible to anything even remotely addictive. I am not disparaging addiction in any way, especially having been addicted to cigarettes for fifty years myself.
The fact that cigarettes were/are modified, chemically, to enhance the effects of nicotine on the brain could easily result in someone who is slightly more susceptible to become "dependent". Again, if it was the highly addictive substance it is normally portrayed as, what ethical research group or peer review team would even consider, let alone permit, using it in research on humans except maybe in a totalitarian regime?
On another note, I got shipping notification of the titanium I ordered and am waiting, impatiently, for it to get here. I'm trying, hard, to hold off rebuilding with Ni200 again.
I think setting your temp limit based on your "idle temp" is a good idea. E-liquid knows where it wants to balance out the heat in /heat out and we know that's a good safe temp point..so add a few degrees for the limit temp and go for it. Makes sense to me.Orion,

So back to the issue of dry burning coils. This morning I took one of my pre coiled tensioned micro contact coils (that's a mouth full) and set my IPV mini to its lowest setting of 5 watts pulse fired it just enough to glow a dark orange so I could compress the coil and work out the hotspots. That was the cleanest tasting vape I have ever had.

I like big fat coils too but I've been aiming around 4mm. I might have to find a bigger mandreland try your 4.5. One problem I'm going to have to face though is fitting the largest diameter coils in my newest atty. It's a 14mm diameter bottom feeder I picked up to explore squonking. I think I'll have to get something bigger. My fingers/thumbs are just way to big to coil that puppy no matter how good the vape.

I remember the first time I got that coil fart I dropped my mod, broke the glass in the atty and cursed 7 blue streaks. It still startles me to this day but I hold my mods tighter.I got my mandrel from Tony. He was kind enough to send me an M5 CCW & CW eye bolts from a metric turnbuckle. I searched all over this country and could find anything that was CCW which works perfectly on my Lemo 2.
I don't know if my belief is a placebo effect but I swear ever since I decided to try it works as I imagined it would. I don't care how many hits in a row you take you just can't dry that puppy out. One negative that some people may find offensive is with the thick wick at 25 watts is it will occasionally cause a gas bubble in the wick to form and when it lets go it really pops. Doesn't bother me put it might be a problem Vaping around other people especially when they start ducking for cover.![]()
Well, I listened to it. Relevant discussion as the OP states doesn't start until the 43 min mark. There is a Q&A afterwards. Nowhere in there does any Pedro make a statement. Nowhere is there any statements attributed to any Pedro. Much ado about nothing. The only thing I can glean from it all, and I'm no PhD, is that it is grossly irresponsible for someone who DOES have a PhD to condemn anyone or anything without at least the most basic of research before they make a statement. Wouldn't you agree, Dr.?
