Ukusasazwa kwehydrogen ngeentsimbi kumaqondo obushushu aphezulu sisihloko esibalulekileyo kwiinkqubo ze-tritium kunye nezithuthi ezisebenzisa i-hydrogen. Ukufundisa ukusasazeka kwilebhu yezinto eziphantsi kwe-undergraduate kunceda kumava okuqala ngemilinganiselo ye-osmotic. Uvavanyo lwenziwe ukubonisa ukungena kwe-hydrogen ngetyhubhu yentsimbi engagqwali. Injongo yalo msebenzi yayikukufumanisa ukuba iziphumo zolu vavanyo zivumelana njani namaxabiso abalaseleyo oncwadi lwe-diffusion coefficient kunye nokunyibilika kwe-hydrogen kwintsimbi engagqwali. I-Hydrogen kunye ne-argon zaxutywa kwi-tank efudumeleyo equlethe ityhubhu ebhityiweyo yentsimbi engagqwali engama-316. Igesi ye-argon purge ecocekileyo yadluliselwa kwityhubhu ukuya kwi-mass spectrometer apho ii-compositional transients zeentlobo zegesi ezifanelekileyo zarekhodwa khona. Ukufaka imodeli yotshintsho lwethiyori kwidatha yovavanyo kwavelisa i-diffusion coefficient kunye nokunyibilika kwe-hydrogen kwintsimbi engagqwali. Uvavanyo lwenziwe ngoxinzelelo olusebenzayo lwe-hydrogen ukusuka kwi-0.01 ukuya kwi-0.5 atm. kunye namaqondo obushushu ukusuka kwi-700 ukuya kwi-783 K. Imodeli yethiyori ihambelana kakuhle nemilo yedatha yokungena ye-transient. Amaxabiso abonwayo okusasazeka kunye nokunyibilika kwehydrogen kwintsimbi engagqwaliyo evela kwezi transients afana namaxabiso oncwadi kunye nomahluko othile. Olu mahluko lunokuchazwa ngeziganeko ezaziwayo. Iziphumo zale ndlela yovavanyo zisondele kakhulu kumaxabiso okusasazeka kunye nokunyibilika apapashiweyo, okuqinisekisa ukuba uvavanyo lungasetyenziswa njengoncedo lokufundisa. Le ndlela inokwandiswa kwezinye izixhobo zophando okanye zokubonisa.

Umhlaza webele ovuvukalayo (IBCC) lolona hlobo lomhlaza webele lunobundlongondlongo nolubulalayo. I-IBC yayikhe yaba sisifo esibulalayo kwihlabathi liphela, kodwa namhlanje ukusinda kweminyaka emi-5 yi-30-40% (Bond, Connoly, & Asci, 2010). I-IBC yayikhe yaba sisifo esibulalayo kwihlabathi liphela, kodwa namhlanje izinga lokusinda kweminyaka emi-5 liyi-30-40% (Bond, Connoly, & Asci, 2010). Когда-то ИБК был смертельно опасным заболеванием, но сегодня 5-летняя выживаемость составляет 30-40% (Bond, Connoly, & Asci, 2010). I-IB yayikhe yaba sisifo esibulalayo, kodwa namhlanje izinga lokusinda kweminyaka emi-5 liyi-30-40% (Bond, Connoly, & Asci, 2010). Когда-то ИБК был смертельно опасным заболеванием, но сегодня 5-летняя выживаемость составляет 30-40% (Bond, Connoly & Asci, 2010). I-IB yayikhe yaba sisifo esibulalayo, kodwa namhlanje izinga lokusinda kweminyaka emi-5 liyi-30-40% (Bond, Connoly & Asci, 2010).I-IBC ibandakanya i-1% ukuya kwi-6% yazo zonke izifo ezixilongwa ngomhlaza webele. Ukunqaba kuyinto eyahlukileyo kugqirha nakwisigulane (Molckovsky et al., 2009). Uninzi lwezigulane lubona ugqirha wazo oyintloko (PCP) kuqala. I-IBC idla ngokuchongwa gwenxa njenge-breast cellulitis okanye i-mastitis. Uninzi lweencwadi ezikwi-IB zipapashwa kwiijenali ze-oncology.

Ukufezekisa le njongo, ii-photocatalytic [2+2] cycloaddition reactions ze-alkenes kunye ne-isocyanates ekukhanyeni okubonakalayo zisetyenzisiwe ukulungiselela ii-antibiotics ze-monocyclic lactam. Umsebenzi wokuqala ugxile ekuphuhliseni iimeko zempendulo yemveliso phakathi kwe-phenylisocyanate kunye ne-transstilbene. Uvavanyo lwakutshanje lugxile ekwandiseni i-reactivity ye-photocatalyst ngokongeza isixa se-stoichiometric se-oxidative quencher. Xa kuhlalutywa imixube ye-reaction equlethe izongezo ze-oxidizing, kufunyenwe iimveliso ezintsha ezininzi. Okwangoku sisebenza ekuhlukaniseni nasekuchazeni ezi mveliso zintsha.
I-Taricha granulosa yi-salamander ekhupha i-neurotoxin tetrodotoxin (TTX) eluswini lwayo. Ii-Salamanders zisebenzisa i-tetrodotoxin njengendlela yokuzikhusela kwizilwanyana ezizingelayo. Abantu abadala, ii-larvae kunye nee-embryo ze-Taricha torosa zibonakalisiwe zine-TTX. Besifuna ukulinganisa ubungakanani be-TTX echithwe zii-salamander kumanqanaba ahlukeneyo obomi bazo, kubandakanya ii-embryos, ii-larvae (ngaphambi nasemva kokubonakala kwemilenze yangasemva), kunye nee-salamander zabantu abadala. Siza kusebenzisa i-gas chromatography edibene ne-mass spectrometry (GCMS) kunye ne-capillary zone electrophoresis (CZE) kunye ne-microarray fluorescence detection ukumisela uxinzelelo lwe-TTX. Injongo yophando lwethu yayikukuqinisekisa ukuba i-capillary zone electrophoresis liqonga elifanelekileyo lokulinganisa i-tetrodotoxin. Ukusetyenziswa kolu phononongo kukufumana amanqanaba asisiseko e-tetrodotoxin ukunceda uphando olongezelelweyo.
Ngokufunda indlela eyaziwayo neyaziwayo yokusabela kweFischer-Indole, iindlela ezinokubakho zokwenziwa kwe-indole kunye ne-carbazole zichongiwe. Le ndlela icetyiswayo yokusabela ibandakanya ukwenziwa kwezinto ezifanayo nezikwinkqubo yeFischer. Ukuba oku kudibana nengeniso eqhelekileyo ephakathi njengoko bekulindelwe, indlela ecetywayo yokusabela kufuneka inike imveliso efanayo nenkqubo yeFischer. Ukuba oku kuyinyaniso, kuya kuchongwa indlela entsha yokusabela kwamakhemikhali.
Impendulo ecetywayo yokwenziwa kwee-indoles (kwaye ekugqibeleni ii-carbazoles) ibandakanya ukuhlanganiswa kwee-compounds ze-aromatic nitroso kwi-cyclic amine moieties kwindlela entsha ye-mechanistic. Isicwangciso esingezantsi sibonisa impendulo entsha ecetywayo. Ukulula kwale mpendulo kuya kubonakala kwisidingo samanyathelo ambalwa kwaye kubize kancinci kwaye kulula ukuphatha ii-reagents kunezinye iindlela zokwenziwa. Eyona nzuzo inkulu kukuba i-hydrazine enobuthi obuphezulu efunekayo ukusebenzisa indlela yeFisher ayifuneki.
Le mpendulo iphandwe phantsi kweemeko ezahlukeneyo zempendulo, kuquka izinyibilikisi ezahlukeneyo, amanqanaba e-pH ahlukeneyo, iindlela ze-microwave kunye neendlela zesiqhelo zempendulo, kwanokusetyenziswa kwee-catalysts ezahlukeneyo.
Le mpendulo iye yafundwa, kodwa ngelishwa ayiphumelelanga. Isizathu soku asikaqinisekiswa. Kufuneka uphando olongezelelekileyo ukuze kuchongwe ukuba kutheni le mpendulo ingaphumelelanga ukuza kuthi ga ngoku kunye nendlela olu lwazi olunokusetyenziswa ngayo ngempumelelo.

Ii-membranes zeeseli kunye neeproteni zazo zidlala indima ebalulekileyo kubomi bemihla ngemihla kwaye zinomdla kakhulu kwabo bafunda ngobomi. Inani elikhulayo lezifundo ligxile kwindima yezi proteni kunye nee-membranes kunye nokusebenzisana kwazo kuphando lwezonyango kunye nethiyori. Kutshanje, ii-bilayers ze-lipid ezixhaswayo (ii-SLBs) zisetyenzisiwe ukucoca iiproteni ze-membrane kusetyenziswa indlela ebizwa ngokuba yi-electrophoresis/electroosmotic focusing (EEF). Nangona le ndlela iqondwa kakuhle ekuqaleni nasekupheleni kokwahlulwa kwe-lipid/protein, ukuziphatha kwezi lipids/proteins phakathi akuqondwa kakuhle. Sizama ukwenza ukulinganisa ikhompyutha okuya kusenza sikwazi ukulinganisa ukuziphatha kwe-lipids kunye neeproteni kuzo zonke izigaba zokwahlulwa. Oku kwenzelwe ukunceda ukuqonda ukusebenzisana kweproteni-lipid kuphando oluzayo.
Iimines ziludidi olubalulekileyo lweekhompawundi ze-organic eziqulathe amaqela asebenzayo (CH=N)). Zikwabizwa ngokuba ziziseko zeSchiff, emva kweSchiff enkulu eyazenza ngo-1864. Zenziwa ziimpendulo zokuxinana phakathi kwee-aldehydes okanye ii-ketones kunye nee-amines. Iimines ezininzi zibonisa umsebenzi obalulekileyo webhayoloji njengomsebenzi wokulwa neentsholongwane, ii-antiviral, kunye nowokulwa nomhlaza. Injongo yethu yayikukwenziwa kweemines ezintsha ngokusabela kwee-N-heterocyclic aldehydes kunye nee-amines. Ezi imines zinokusebenza njengee-bidentate ligands kwaye zenze izakhiwo zendandatho ezizinzileyo ezineemetal eziguqukayo. Enye injongo yeprojekthi yethu kukuhlanganiswa kweemines ezintsha ngeemetal ze-d8 (oko kukuthi i-nickel, iplatinum kunye ne-palladium). Sinethemba lokuba i-platinum complex eyenziweyo iya kuba yi-analogue ye-cisplatin yeziyobisi ezichasene nomhlaza. Emva kokwenziwa ngempumelelo, ii-metal complexes ziya kuvavanywa ukuba zifuna lo msebenzi webhayoloji.
Siye savelisa iimines ezintsha ze-5-aminouracil kunye nee-aldehydes ezintathu ezahlukeneyo ze-N-heterocyclic. Idatha ye-1H-NMR kunye ne-IR ibonisa ukuba siye savelisa iimines ezifunekayo. Umsebenzi uyaqhubeka ekuhlukaniseni iimveliso ezicocekileyo kunye nokuhlanganiswa kwee-complexes zazo zesinyithi. Ipropati eluncedo yeemines zethu ezisandula ukwenziwa kukuba zikhanya kakhulu kwindawo eluhlaza okwesibhakabhaka yokukhanya okubonakalayo.
Ii-Alkylamines (RNH2) ziludidi olubalulekileyo lweemolekyuli zendalo, kuquka iimveliso zendalo ezisebenzayo kwibhayoloji kunye namayeza. Zifumaneka kwiikhompawundi ezininzi ezibalulekileyo ezifana ne-morphine, i-dopamine kunye nazo zonke iiproteni. Ke ngoko, ukuveliswa kwee-alkylamines kubaluleke kakhulu ekuvelisweni kwamayeza amatsha nangcono. Lo msebenzi uzinikele ekusebenziseni ii-alkylborane intermediates ekwakhiweni kweebhondi ze-nitrogen-carbon ze-alkylamines. Ukufakelwa kwee-alkenes nge-borane (BH3) kulandelwa yi-oxidation nge-hydrogen peroxide (H2O2) kuyaziwa. Sicebisa ukusetyenziswa kwale alkylborane intermediate kulandelwe kukusetyenziswa kwee-nitrogen equivalent ze-hydrogen peroxide ukubonelela ukufikelela kwi-alkylamines ezivela kwi-alkenes. Ukukhetha indawo ye-anti-Markovnikov kufana ne-hydroboroxidation. Impendulo yokulawula i-oxidation yi-hydroboration yenziwe ngempumelelo kwi-transstilbene. Iimeko zovavanyo eziphumelelayo zeempendulo ezifunekayo ziyaphuhliswa okwangoku.
Iimpendulo ezikhuthazwa ziimetali zotshintsho zingasetyenziswa kwi-organic synthesis yamayeza, izinto (iiplastiki), kunye namafutha. Ulwakhiwo kunye nee-elektroniki ze-phosphine ligands ezidityaniswe neziko le-transition metal zinokuchaphazela kakhulu i-reactivity yee-catalysts. Olu phando luzinikele ekuhlanganisweni kwee-phosphine ligands ezintsha ze-reactions ezintsha ezikhuthazwa ziimetali zotshintsho. I-trialkylphosphine ligand ephendula kakhulu i-diethyl tert-butylphosphine yenziwe kwaye yakhuseleka njenge-borane adduct evela kwi-phosphorus trichloride kunye nee-Grignard reagents ezifanelekileyo kwisivuno esipheleleyo se-66% (amanyathelo ama-4). Kufunyenwe ukuba iziphumo ze-steric kunye ne-elektroniki zee-Grignard reagents zinempembelelo ebalulekileyo kwi-reactivity kunye nokukhetha kwe-reaction yamanyathelo amathathu yokongezwa kwe-nucleophilic kumaziko e-phosphorus (III). Umsebenzi wexesha elizayo uza kugxila ekuphuhliseni inkqubo ngokubanzi yokulungiselela i-trialkylphosphine borane adducts ezifunwayo ezivela kwi-phosphorus trichloride kwisivuno esiphezulu.

I-Osteoporosis sisifo esiqhelekileyo apho kuqhawuka amathambo amaninzi. Ixhaphake kakhulu emqolo, esinqeni, okanye esihlahleni kwaye inokubangela ukwenzakala okanye ukufa okukhulu. Ukuxhaphaka kwe-osteoporosis eMelika kuqikelelwa ukuba kuya kwanda ukusuka kwizigidi ezili-10 ukuya ngaphezulu kwezigidi ezili-14 ngo-2012 (ngokusekwe kwidatha yoBalo lwabantu luka-2000). Njengoko uxinano lwamathambo luphezulu besebancinci, umngcipheko we-osteoporosis uyancipha. Ukuthatha inxaxheba kwimisebenzi yomzimba, efana nemidlalo yezemidlalo ehleliweyo, kudla ngokunxulunyaniswa nokwanda koxinano lwamathambo.
Iprojekthi yophando iphande le mibuzo ilandelayo: Ngaba uxinano lwamathambo omntu luyatshintsha xa ethatha inxaxheba kwimisebenzi yomzimba?
Olu phononongo lufumanise unxibelelwano oluhle phakathi komsebenzi womzimba wobomi bonke kunye noxinano lweeminerali zamathambo, nto leyo ebonisa ukuba abantu ababesebenza ngokomzimba ubomi babo bonke babenoxinano olukhulu lwamathambo kunabantu ababenomsebenzi ophantsi wobomi bonke. . Abantu abangazange basebenze ngokomzimba banamathuba amaninzi okuba noxinano oluphantsi lwamathambo (malunga ne-10% yabemi bethu) kunabantu abanemisebenzi ephantsi, ephakathi nephezulu. Izifundo zibonise ukuba njengoko amanqanaba omsebenzi esanda, amathuba okuba noxinano oluqhelekileyo okanye oluphezulu lwamathambo ayanda.

Ukubonisa ubukho bebhaktheriya ye-E. coli kwisampulu nganye yamanzi kuya kukuvumela ukuba ujonge umgangatho wamanzi asebhotileni nawasempompini. IiColiforms zizinto eziphilayo ezibonisa ubukho bebhaktheriya enye efumanisa ubukho bezifo ezininzi. Akukhuthazwa ukujonga ezinye iintsholongwane ukuba zikhona ezinye izifo eziyingozi ngenxa yendawo yazo eyahlukileyo. (Byamukama kunye noKanshiime et al., 1999). I-E. coli inokuphila emanzini okusela iiveki ezi-4 ukuya kwezi-12 kuxhomekeke kwiimeko zendalo (Rice, Karlin, Allen, 2012). Iimpawu ezilishumi ezahlukeneyo zamanzi asebhotileni ziya kuvavanywa iibhaktheriya ze-E. coli, kunye namanzi asepomponi avela kumakhaya alishumi ahlukeneyo. Uhlobo ngalunye lwamanzi asebhotileni kunye namanzi asepomponi okusetyenziswa ekhaya luvezwa kathathu. Kwangaxeshanye, inani elikhulu leesampuli zamanzi libekwa kwi-incubator ukuze kuhlalutywe kwaye kukhuthazwe ukukhula kwebhaktheriya. Oku kuya kumisela ubumsulwa besampulu nganye. Iisampuli ziya kubekwa kwigumbi elimnyama apho ukukhanya kwe-UV kuya kusetyenziswa ukukhanyisa iisampuli ukuze kubonwe ubukho be-E. coli. (Rice, Carlin, Allen, 2012).
Iintaba zaseSan Francisco kumzantsi-ntshona we-Utah bezimbiwa kakhulu kwiminyaka embalwa edlulileyo. Ukwembiwa kugxile kakhulu kwi-quartz monzonites ze-Tertiary quartz, ii-Paleozoic limestones ezingenelelayo. Imithombo ebalulekileyo ivela kwiindawo ezimbini ezinkulu ezinengxaki ezityebileyo kwi-hydrothermal porphyry deposits, kodwa indawo ezidibana kuyo ezi ngxaki ayibhalwanga kakuhle ngenxa yokungabikho kakuhle kwamatye. Besebenza nenkampani yezemigodi yasekuhlaleni, abafundi baseSouthern Utah baqale ukwenza imaphu yokuqala ukuze bafumane kwaye bachaze le ndawo yokuwela iimpazamo ngaphambi kokuba baqhubeke nophando. Sidwebe indawo yee-fractures eziveziweyo sisebenzisa isixhobo se-Triton Juno GPS kwaye silinganise uxinano lwazo kunye nokuqhelana kwazo nee-fracture sisebenzisa i-Brenton balance kunye ne-compass. Iziphumo ze-rose diagrams, ii-stereograms kunye neemaphu zibonisa ukuba kukho iindawo ezidibanayo ngaphakathi kwendawo yophando. Uxinano lwee-fracture luyanda njengoko kusondela iindawo ezidibanayo, ngakumbi kwenye yeendlela zokuqhekeka, kwaye ngokuqhelekileyo iindawo ezidibanayo zeeminerali kwindawo ezidibanayo. Sicebisa ukuba kuhlolwe ngakumbi ngendlela yokumba i-core kwiindawo ezidibanayo zeeminerali ukuze kuchongwe ukuba kunokwenzeka na ukusetyenziswa kwezoqoqosho.
Iintaba zaseHuahua kufutshane neMinasville, eUtah, ziye zahlolwa ngeeminerali kwiminyaka embalwa edlulileyo. Izixhobo zigxile kwiimpazamo ze-hydrothermal eziguquliweyo yi-hydrothermal, ngokuqhelekileyo apho ii-quartz monzonites ze-tertiary zingena kwi-Paleozoic limestones. Ukongeza kwi-Tertiary magmatism, iintaba zaseHuahua zibonisa amandla abalulekileyo e-Late Cretaceous orogeny yaseSeville, zibeka amatye e-Paleozoic sedimentary phezu kwamatye e-Middle Cretaceous sedimentary. Ngexesha leprojekthi yemephu yesakhiwo kuloo ndawo, ilitye lesanti laseNavajo elisezantsi kweBlue Mountains Thrust lafunyaniswa ukuba liye lenza i-hydrothermal silicification, nto leyo eyenza ukuba lifane ne-quartzite. Emva kokuhlolwa ngokusondeleyo, kwafunyaniswa ezinye iimineralization ze-hydrothermal. Ezi ziphumo zitshintsha ingqwalasela yophando ukusuka ekubhaleni i-structural geology ukuya ekubhaleni utshintsho olukhethekileyo lwe-hydrothermal kwi-sandstones zaseNavajo.
Olu phononongo luquka ezi ndlela zilandelayo. Kwindawo yeeNtaba eziluhlaza okwesibhakabhaka, kukhangelwa iindawo ezikufutshane nexesha leSevier. Iisampulu zesanti zeJurassic Navajo zaqokelelwa kwaye kwenziwa amacandelo amancinci ukuhlalutya umxholo wesinyithi welitye. Iisampulu ezifunyenwe kufutshane nencam esempuma yeBlue Mountains Thrust Fault zaziqulethe i-quartz, i-hematite, kunye nezinye iintsimbi ezincinci. Ukwenziwa kweeminerali akutyebi kangako, kodwa ngobunzulu obukhulayo, iindawo zeesinyithi kwimithambo zinokuba zininzi ngakumbi. Uhlalutyo olongezelelweyo, olufana nohlalutyo lobunzima kunye nedatha engundoqo, luyafuneka ukuze kuchongwe ixabiso lokwenziwa kweeminerali.
