Kunetsekana kuti magandanga anogona kuburitsa chimiro chitsva uye chine ngozi zvakanyanya chekuputika kunokonzeresa kuchengetedzwa kweshangu dzevatyairi panhandare yendege uye zvirambidzo pazvinwiwa zviri mumukwende hazvina hwaro, masayendisiti akashuma Kurume 24.

Ndichitaura paMusangano weNyika wechi237 weAmerican Chemical Society muS alt Lake City, Utah, Gerard Harbison, Ph.D., nevamwe vaaishanda navo vakatsanangura vachishandisa kuenzanisa kwekombuta kuongorora zvakasiyana-siyana zvingangoputika zvinoputika zveperoxide zvakafanana. Kemikari kirasi se triacetone triperoxide (TATP). Kuputika uku kwakasimba, kuri nyore kugadzira kwakashandiswa ne "bhomba reshangu," Richard Reid, mukuedza kwake kutadza kuputitsa ndege ye transatlantic muna 2001.TATP yakashandiswawo nemabhomba ekuPalestinian Intifada.

Chikwata chaHarbison chakashamiswa ne "Internet lore," mishumo inotenderera paWebhu ichiti kusikwa kwechimwe chinoputika - tetracetone tetraperoxide (TeATeP) - inodaidzwa kuti ihama inouraya kuTATP. Vakatanga vachishanda pakuona nzira dzekuona mabhomba eperoxide eDefence Advanced Research Projects Agency, boka rakatanga kuferefeta chimiro cheTeATeP kuona kuti ingangoshandiswa sei sechombo chegandanga.

"Ongororo yedu inoratidza kuti zvingangove zvitsva uye zvinoparadza zvinhu zvegandanga, izvo zvingaite mutero wedu wekuona, zvinogona kunge zvisina kugadzikana kuti tiite synthesis inoshanda," akadaro Harbison, chiremba wemakemikari paYunivhesiti yeNebraska-Lincoln. "Tinofunga kuti hazvigoneki kuti chero ipi zvayo yekare yakagadziriswa yakabudirira chaizvo, uye nhema dzeIndaneti pamusoro peTeATeP haisi chimwe chinhu kunze kweizvozvo. Saka mashoko akanaka ndeokuti ichi chinhu chatisingafaniri kunetseka nezvazvo."

Boka rakaongorora makumi maviri ezvimiro zvemamorekuru emhando dzakasiyana siyana dzeacetone peroxide uye vakawana kuti zvinhu zvese zvakakura kupfuura TATP zvinogona kunge zviri nyore kuti zvishandiswe sezvombo. "Masimba atiri kuona mukuongorora akawandisa zvakakwana," akadaro Harbison, achiwedzera kuti ongororo yezvakaitika kare TeATEP synthesis mishumo yakamutsa mibvunzo yakawanda. "Mukatarisa mabhuku chaiwo ari pamusoro pevanhu vanozviti vakagadzira TeATeP, hazvina kujeka. Tinofunga kuti pamwe zvakaitika vanhu vachifunga kuti vari kugadzira TeAteP ndezvekuti ivo vaigadzira TATP."

Ichi chikanganiso chekubatanidza chakajairika uye kazhinji chinouraya, Harbison akadaro. Paunenge uchiedza kugadzira TATP, hama isina kugadzikana, diacetone diperoxide, kazhinji inogadzirwa. "Chinhu chakanaka chekuita izvi pakombuta chekutanga chakachengeteka, uye mhedzisiro yedu iri padyo neyakayerwa kuyerwa zvekuti tine chivimbo chakanyanya nezvatiri kuita," akadaro Harbison."Isu tave pachinhanho chekuti tinogona kuongorora kutyisidzira - mamorekuru anogona kunge aine njodzi - uye tinogona kunyatso funga kuti mamorekuru aya achaunza njodzi mune ramangwana." Tinogona kuedza zvinhu nemakomputa. pamwero wekuvimbika unofananidzwa nekuita iwe pachako synthesis uye kuongorora zvinhu iwe pachako."

Kune kutsvagisa kwakawanda kunobata nekutyisidzira kunozivikanwa, Harbison akadaro. Asi tsvakiridzo yemapoka ake inotarisana nepfungwa yekuti kutyisidzira kuri kubuda kunogara kuripo. "Zvichida munoda kufungidzira kutyisidzira kusati kwauya. Isu tave kuzvisundira mberi zvishoma uye tichikurukura zvingangotyisidzira."

"Tichishandisa computational chemistry, tinokwanisa kudzikisira nzvimbo yenjodzi dzingangoitika, zvinhu zvinenge zvisisipo. Kuonekwa kwemudziyo asiwo izvo zvisingashande, uye isu hatifanirwe kuzviedza kunze (nekuedza).Takaita makore mashanu apfuura."
