“…The maximum emission intensity is obtained for the sample annealed at 1000 °C for 2 hours. The authors have also measured the lifetime corresponding to (5)S(2) → (5)I(8) transition and found that lifetime values follow the trend of upconversion intensity. …”

“…In addition, we show that the detection limits are sufficient to also observe subtle spectroscopic signatures in XAS spectra with integration times of about 1–2 hours using a bright undulator beamline. This novel setup opens new research opportunities for studying the nucleation of new phases in multicomponent aerosol systems in situ, and for investigating (photo-) chemical reactions on airborne matter, as relevant to both atmospheric science and also for general chemical application.…”

“…We demonstrate unassisted (bias‐free) water splitting by wiring Si|IO‐TiO(2)|H(2)ase to a modified BiVO(4) photoanode in a photoelectrochemical (PEC) cell during several hours of irradiation. Connecting the Si|IO‐TiO(2)|H(2)ase to a photosystem II (PSII) photoanode provides proof of concept for an engineered Z‐scheme that replaces the non‐complementary, natural light absorber photosystem I with a complementary abiotic silicon photocathode.…”

“…According to respondents, various forms of sexual harassment included: (1) inappropriate staring or leering in a sexual manner; (2) sexually suggestive comments/jokes/name-calling; (3) intrusive questions about your sex life/physical appearance that were offensive; (4) someone showing his/her private parts/half or fully-naked body offensively; (5) unwelcome touching, hugging, kissing or other inappropriate physical contact; (6) sexually explicit calls or messages; (7) repeated or inappropriate invitations to dates; (8) sexually explicit pictures, posters or other material; (9) actual or attempted rape or sexual assault; (10) video/photo taking of survivors of a sexual nature; (11) requests or pressure for sex or other sexual acts; and/or (12) other forms of sexual harassment. 56.2% of the sample (513 women) insisted that they had experienced at least one of the aforementioned forms of sexual assault, while 11.7% (107 women) confirmed that they had experienced sexual assault, but weren't willing to describe their experiences in detail. …”
