Arthur T Knackerbracket has found the following story:

Scientists have theorized that organometallic halide perovskites -- a class of light harvesting "wonder" materials for applications in solar cells and quantum electronics -- are so promising due to an unseen yet highly controversial mechanism called the Rashba effect. Scientists at the U.S. Department of Energy's Ames Laboratory have now experimentally proven the existence of the effect in bulk perovskites, using short microwave bursts of light to both produce and then record a rhythm, much like music, of the quantum coupled motion of atoms and electrons in these materials.

[...] Research thus far hypothesized that the materials' extraordinary electronic, magnetic and optical properties are related to the Rashba effect, a mechanism that controls the magnetic and electronic structure and charge carrier lifetimes. But despite recent intense study and debate, conclusive evidence of Rashba effects in bulk organometallic halide perovskites, used in the most efficient perovskite solar cells, remained highly elusive.

[...] "Our discovery settles the debate of the presence of Rashba effects: They do exist in bulk metal halide perovskite materials." said Jigang Wang, senior scientist at Ames Laboratory and professor of physics at Iowa State University. "By steering quantum motions of atoms and electrons to engineer Rashba split bands, we achieve a significant leap forward for the fundamental discovery of the effect which had been hidden by random local fluctuations, and also open exciting opportunities for spintronic and photovoltaic applications based on quantum control of perovskite materials."

    Still sore @ me kicking yer ass publicly tranny freak https://soylentnews.org/comments.pl?noupdate=1&sid=33430&page=1&cid=889582#commentwrap [soylentnews.org] ? Yes, OBVIOUSLY (lol).

    You did that all to yourself since you are incompetent & STUPID & a TWISTED ABOMINATION sick in the head TRANNY weirdo LOSER (but you sure TRY to "play smart" but vs. me you FELL FLAT ON YOUR FACE publicly, lol - no denying it loser).

    You also threw a raged shitfit there, calling for the PUNK SITE OWNER HERE (help me mommy, lmao) to burn your account in due to your BLUNDERING shame publicly vs. me you can't hide, hehehe!

    THEN YOU IMPERSONATED ME making it look like I APOLOGIZED TO YOU https://soylentnews.org/comments.pl?noupdate=1&sid=35327&page=1&cid=937346#commentwrap [soylentnews.org] you fucking DECEITFUL disgusting LYING TRANNY weirdo LOSER?

    Bullshit I did!

    Why WOULD I after LIES about me you spew (just a few below prove it you FUCK) & after I BLEW YOUR DUMB ASS AWAY in the link above?

    Hahahahaha - OH, the PUBLIC HUMILIATION for you, lol!

    Doubtless due to ALL THE DRUGS YOU ARE ON (& YES, I KNOW that you are) & you SHOULD have had your account deleted.

    You need to be DELETED from this LIFE you sick in the head FREAK "TrAnStEsTiCuLaR MONSTROSITY".

    Barbara Hudson LIKES TO TELL LIES ABOUT ME (projecting "its" OWN issues in being a SAW OFF ITS OWN COCK & BALLS useless loser "self DISABLED" TRANNY FREAK, lol - that's no disability, it's INSANITY clearly!)

    You lie saying I don't work OR that I haven't in "25 yrs" etc.?

    WRONG!

    I've said it MANY TIMES to YOU directly, LYING FUCK YOU ARE, that I still contract idiot but I don't HAVE to as I run my own show in other business!

    FACT: Still - I haven't HAD to work for ANYONE but myself really since 2007 freak.

    I've told you before I RUN MY OWN BUSINESS & actually have WORTH + real estate holdings galore!

    (That's MY real worth, & you barbara TOM hudson don't have SHIT, you USELESS LEECH WELFARE SUCKING "DISABLED" total BULLSHIT ARTIST twisted TRANZOID loser (by SAWING OFF YOUR COCK & BALLS since you are an INSANE whacko that did that to yourself too, OMG, lol) - truer words were NEVER spoken about you, loser).

    You "VOLUNTEER"? LOL - doing what??

    Barbara Hudson's SUCK SERVICE for OLD HOMOS @ the VA Hospital??

    LMAO - probably.

    (Some "Essential Service", lmao).

    * I hope this shithole waste of a site closes off ANON POSTS - why? Barely ANYONE comes here as is, do that, this place will go to ZERO & have to go away (& thus, so will you freak, lol)

    Most of all - you & your sockpuppet "friends" (just you most likely using multiple accounts) ARE REDUCED TO IMPERSONATING ME since you can't manage to prove me wrong in that TOPMOST LINK to your UTTER PUBLIC HUMILIATION vs. myself, in IMPERSONATIONS of ME like e.g. https://soylentnews.org/comments.pl?noupdate=1&sid=37178&page=1&cid=985582#commentwrap [soylentnews.org] (since I didn't write the post you replied to)!

    It proves EVERYTHING that needs proving here along w/ my FACTUAL STATEMENTS here too about you, scumbag TRANSTESTICLE FREAK!

    All in addition to your MULTIPLE SELF-DEFEATS vs. me in the TOPMOST LINK above you CAN'T STAND since you were SO STUPID blundering mistake after mistake vs. me in its points...

    APK

    P.S.=> Lastly: FREAK, I've done MORE THAN YOU EVER HAVE or EVER WILL you USELESS no skills BULLSHIT ARTIST LAZY STUPID piece of TWISTO TRANNY CRAP FREAK ABOMINATION & you, + most likely MOST here, KNOW already!

    Anyone can see the link I posted above as to that much & they'll see results I produced that did well vs. threats online w/ @ LEAST 1/4 MILLION USERS OF MY WORK TO DATE

    + TONS MORE that YES, you ARE AWARE OF in publications in computing I have to MY NAME!

    (You don't & NEVER will loser)

    That's all in addition to my being paid well for code I wrote that SELLS TO THIS VERY DAY from a certified Microsoft partner that placed as a FINALIST @ Microsoft TechEd 2000-2002 in its HARDEST CATEGORY SQLServer Performance Enhancement 2 yrs. in a ROW you DO-NOTHING INCAPABLE imcompetent FAILURE LOSER you TRULY are!

    So, & I've asked this of you before (to SHAME your LAZY incompetent ass): YOU'VE DONE MORE/BETTER? Hell no!

    (& a LOSER you KNOW you ARE never can or will, freak (& we all know it - prove otherwise - YOU CAN'T since you haven't EVER DONE SHIT of ANY worth whatsoever you USELESS mentally TWISTED trantesticular MONSTROSITY abberration abomination). I do well in all things - whereas YOU do nothing but "CHATTER ONLINE" like the FUCKING FOOL FREAK TRANNY LOSER you are TWISTO - everyone KNOWS what YOU are, lol & it is DISGUSTING you RIDICULOUS ABOMINATION))... apk
