Evidence of enhanced photocurrent response in corannulene films
Nadya Patukhova, Layla Martin Samos, Egona Pavlica, Gvido Bratina, 2017, izvirni znanstveni članek

Opis: Photoconductivity spectra measured in non-crystalline corannulene thin layers are compared to optical absorption in solution phase and thin films. The unexpected enhanced photoconductivity is correlated with GW–BSE theoretical predictions of corannulene gas-phase excitonic spectra. Theoretical analysis reveals a consistent contribution involving transitions to Super Atomic Molecular Orbitals (SAMOs), a unique set of diffuse orbitals typical of curved conjugated constructs. Results suggest SAMO population via direct photoexcitation as a potential mechanism towards exploiting these diffuse orbitals as conducting channels in suitably assembled quantum nanostructures or solids.

Španska gripa na Goriškem v letu 1918
Martin Batagelj, 2020, diplomsko delo

Opis: V uvodu diplomske naloge bom najprej utemeljil razloge za izbrano temo ter s pomočjo literature opisal bolezen in njene značilnosti ter natančno predstavil simptome. V nadaljevanju se bom posvetil orisu problematike na globalni ravni, torej začetku širjenja pandemije po svetu, saj naj bi bolezen aprila 1918 z okuženimi ameriškimi vojaki začela svoj smrtonosni pohod po Evropi, kjer se je razširila po bojnem polju in med civilisti. Seveda bom na tem mestu predstavil tudi vlogo bolezni pri odvijanju vojne ter na kakšen način je pandemija vplivala na njen razplet. Ob tem bom izpostavil posameznika, ki je pri iskanju rešitve problema namenil veliko truda ter kot načelnik zdravstvene službe v Manchestru z daljnovidnimi nasveti in ukrepi preprečil, da bi bolezen terjala še večji davek. To je bil škotski zdravnik dr. James Niven, pri opisu njegovega prispevka proti pandemiji pa mi bodo pomagala tudi poročila njegovih opažanj obolelih. V osrednjem delu diplomske naloge se bom najprej posvetil širjenju španske gripe na področju današnje Slovenije. Na tem mestu bom predstavil odziv medijev na pojav in smrtonosnost gripe; predvsem v časopisih Slovenec, Slovenski narod, Štajerc in še drugih. V veliko pomoč mi bodo tudi šolske, župnijske in ostale kronike, ki so jih ljudje pisali v tistih dneh. Največjo pozornost pa bom namenil pojavu in posledicam pandemije na Goriškem. Na tem mestu bom na kratko orisal tudi stanje v regiji po soških bitkah, stanje beguncev in vrnitev vojakov s front ter obširno predstavil pojav in širjenje bolezni ter odziv nanjo. Pri tem si bom pomagal z lokalnimi in župnijskimi kronikami ter časopisnimi članki. Nazadnje bom predstavil resnično zgodbo o tem, kako se moji predniki soočali s špansko gripo. Diplomsko delo bom zaključil s sklepom, v katerem bom povzel celotno temo diplomske naloge, poudaril glavna spoznanja pri njeni izdelavi in predstavil medicinske raziskave povezane s špansko gripo v 21. stoletju.

Trace detection of C2H2 in ambient air using continuous wave cavity ring-down spectroscopy combined with sample pre-concentration
Orr-Ewing Andrew, Damien Martin, Iain White, Roberto Grilli, Ruth Lindley, Manik Pradhan, 2008, izvirni znanstveni članek

Opis: Continuous wave cavity ring-down spectroscopy (cw-CRDS) coupled with sample pre-concentration has been used to measure acetylene (C2H2) mixing ratios in ambient air. Measurements were made in the near-infrared region (λ∼1535.393 nm), using the P(17) rotational line of the (ν1+ν3) vibrational combination band, a region free from interference by overlapping spectral absorption features of other air constituents. The spectrometer is shown to be capable of fast, quantitative and precise C2H2 mixing ratio determinations without the need for gas chromatographic (GC) separation. The current detection limit of the spectrometer following sample pre-concentration is estimated to be 35 parts per trillion by volume (pptv), which is sufficient for direct atmospheric detection of C2H2 at concentrations typical of both urban and rural environments. The CRDS apparatus performance was compared with an instrument using GC separation and flame ionization detection (GC-FID); both techniques were used to analyze air samples collected within and outside the laboratory. These measurements were shown to be in quantitative agreement. The indoor air sample was found to contain C2H2 at a mixing ratio of 3.87±0.22 ppbv (3.90±0.23 ppbv by GC-FID), and the C2H2 fractions in the outside air samples collected on two separate days from urban locations were 1.83±0.20 and 0.69±0.14 ppbv (1.18±0.09 and 0.60±0.04 ppbv by GC-FID). The discrepancy in the first outdoor air sample is attributed to degradation over a 2-month interval between the cw-CRDS and GC-FID analyses.
