Helm­holtz-Zen­trum Dres­den-Ros­sen­dorf e.V.

Through cut­ting-edge research in the fields of ENERGY, HEALTH and MAT­TER, Helm­holtz-Zen­trum Dresden-Rossen­dorf (HZDR) solves some of the press­ing soci­etal and indus­trial chal­lenges of our time. Join our 1.500 employ­ees from more than 50 nations at one of our six research sites and help us mov­ing research to the next level!

The Insti­tute of Resource Eco­logy (IRE) per­forms research to pro­tect humans and the envir­on­ment from haz­ards caused by pol­lut­ants res­ult­ing from tech­nical pro­cesses that pro­duce energy and raw mater­i­als. One major goal is gain­ing a bet­ter under­stand­ing of fun­da­mental pro­cesses defin­ing trans­port and accu­mu­la­tion of radi­otoxic ele­ments in the geo- and bio­sphere includ­ing the food chain.

The Depart­ment of Sur­face Pro­cesses is look­ing for a

PhD stu­dent (f/m/d) Tech­ne­tium inter­ac­tion with meta­bol­ites and Fe(II) min­er­als

PhD stu­dent (f/m/d) Tech­ne­tium inter­ac­tion with meta­bol­ites and Fe(II) min­er­als

The pos­i­tion will be avail­able from 1 April 2023. The employ­ment con­tract is lim­ited to three years.

Tc is the light­est ele­ment with only radio­act­ive iso­topes. Its molecu­lar inter­ac­tions in the envir­on­ment are poorly under­stood. The Ph.D. stud­ies will focus on the inter­ac­tion of Tc with meta­bol­ites and with Fe(II) min­er­als. Moreo­ver, the impact of meta­bol­ites on min­eral dis­sol­u­tion will be stud­ied. The inter­ac­tions will be com­pre­hens­ively quan­ti­fied and char­ac­ter­ized to iden­tify the Tc molecu­lar struc­ture in solu­tion and the mech­an­ism respons­ible for Tc remo­val by min­er­als.

The PhD stud­ies are part of the BMBF fun­ded young invest­ig­ator group (02NUK072) “Wech­sel­wir­kung von Tech­ne­tium mit Mik­roor­gan­is­men, Meta­bol­iten und an Min­eral-Was­ser Gren­zflä­chen – Radi­oöko­lo­gis­che Betrach­tun­gen” (“Inter­ac­tions of Tech­ne­tium with microor­gan­ism, meta­bol­ites and at the min­eral-water inter­face – radi­oeco­lo­gical con­sid­er­a­tions”). The aim of the young invest­ig­ator group is to char­ac­ter­ize the inter­ac­tion of Tc with occur­ring mater­ial in the bio­sphere (microor­gan­isms, meta­bol­ites and min­er­als) under com­plex con­di­tions using a vari­ety of spec­tro­scopic tech­niques as well as wet chem­istry and elec­tro­chem­istry.”

Working field:

  • Determ­in­a­tion of Tc com­plex form­a­tion con­stants with meta­bol­ites
  • Syn­the­sis and char­ac­ter­iz­a­tion of Fe(II) min­er­als
  • Quan­ti­fic­a­tion of Fe(II) min­eral dis­sol­u­tion rates in pres­ence of meta­bol­ites
  • Tech­ne­tium reten­tion exper­i­ments with Fe(II) min­er­als
  • Char­ac­ter­iz­a­tion of the Tc struc­tural envir­on­ment both in solu­tion (Tc-meta­bol­ite com­ple­xes) or in the solid phase (Tc-Fe(II) min­eral inter­ac­tion) by spec­tro­scopic (e.g. UV-vis, Raman, infra­red, nuc­lear mag­netic res­on­ance, X-ray absorp­tion spec­tro­scop­ies) and micro­scopic (e.g., scan­ning and trans­mis­sion elec­tron micro­scopy) tech­niques
  • Pre­sent­a­tion of res­ults at inter­na­tio­nal con­fer­ences and their pub­lic­a­tion in peer-reviewed journ­als

Requirements:

  • Very good uni­ver­sity degree in nat­ural sci­ence, pre­fer­ably in chem­istry, bio­chem­istry, or geo­sci­ence (mas­ter or dip­loma)
  • Exper­i­ence in spec­tro­scopy (Raman, infra­red, X-ray pho­to­elec­tron spec­tro­scopy, nuc­lear mag­netic res­on­ance) and other phy­sico-chem­ical char­ac­ter­iz­a­tion tech­niques (X-ray dif­frac­tion, elec­tron micro­scopy) is help­ful
  • Exper­i­ence in exper­i­men­tal lab work, high motiv­a­tion, and self-ini­ti­ation
  • Will­ing­ness to handle open radio­act­ive mater­i­als in a radi­ation safety con­trol­led lab is requi­red
  • Abil­ity to com­mu­nic­ate and con­duct work in an inter­dis­cip­lin­ary rese­arch team (radio­chem­istry, bio­chem­istry, geo­chem­istry, phys­ical chem­istry) and will­ing­ness to par­ti­cip­ate in sci­ent­i­fic con­fer­ences and work­shops
  • Excel­lent flu­ent com­mu­nic­a­tion skills in (sci­ent­i­fic) Eng­lish. A basic Ger­man know­ledge is an advant­age

  • An excit­ing work­ing envir­on­ment on an attract­ive rese­arch cam­pus and a work­place in the middle of nature
  • Sci­ent­i­fic excel­lence and extens­ive pro­fes­sio­nal net­work­ing oppor­tun­it­ies
