“Green” Aqueous Synthesis, Structural, and Optical Properties of Quaternary Cu2ZnSnS4 and Cu2NiSnS4 Nanocrystals

open access: yesphysica status solidi (b), EarlyView.
Novel Cu–Ni–Sn–S nanocrystals (NCs) stabilized with thioglycolic acid are synthesized in aqueous solutions. The structural and optical properties of Cu–Ni–Sn–S NCs are examined in colloidal solutions and thin films and compared to those of Cu–Zn–Sn–S NCs. The absorption coefficient is α > 104 cm−1 at 400 nm with an estimated Eg≈2.2 eV.

Mosaic CCD method: A new technique for observing dynamics of cometary magnetospheres [PDF]

open access: yes
On April 29, 1990, the plasma tail of Comet Austin was observed with a CCD camera on the 105-cm Schmidt telescope at the Kiso Observatory of the University of Tokyo. The area of the CCD used in this observation is only about 1 sq cm.

Psychedelic‐assisted treatment for substance use disorder: A narrative systematic review

open access: yesAddiction, EarlyView.
Abstract Background and aims This is the first systematic review of the extant literature on all major psychedelic‐assisted treatment for alcohol use disorder (AUD), tobacco use disorder (TUD) and other substance use disorders (SUD). We aimed to summarise the evidence for efficacy of psychedelic‐assisted treatment for AUD, TUD, and SUD; to evaluate its

Molecular ions in comet tails

open access: yesThe Astrophysical Journal, 1976
Band intensities of the molecular ions CH/sup +/, CO/sup +/, N/sub 2//sup +/, and H/sub 2/O/sup +/ have been determined on an absolute scale from tail spectra of comet Kohoutek (1973f) and comet Bradfield (1974b). Photoionization and photodissociation rates have been computed for CH, CO, and N/sub 2/.

Effectiveness and safety of repeated photodynamic therapy in recurrent central serous chorioretinopathy

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To evaluate anatomical and functional outcomes after a second photodynamic therapy (PDT) in patients with central serous chorioretinopathy (CSC), who had a recurrence of subretinal fluid (SRF) after a previously successful PDT. Methods In this multicentre retrospective cohort study, we included patients with CSC who underwent a second ...
