    Abstract: Solar-to-hydrogen generation is a promising approach to generate clean and renewable fuel. Nanohybrid structures such as CdSe@CdS-Pt nanorods were found favorable for this task (attaining 100% photon-to-hydrogen production efficiency); yet the rods cannot support overall water splitting. The key limitation seems to be the rate of hole extraction from the semiconductor, jeopardizing both activity and stability. It is suggested that hole extraction might be improved via tuning the rod’s dimensions, specifically the width of the CdS shell around the CdSe seed in which the holes reside. In this contribution, we successfully attain atomic-scale control over the width of CdSe@CdS nanorods, which enables us to verify this hypothesis and explore the intricate influence of shell diameter over hole quenching and photocatalytic activity towards H2 production. A non-monotonic effect of the rod’s diameter is revealed, and the underlying mechanism for this observation is discussed, alongside implications towards the future design of nanoscale photocatalysts.

    Abstract: The use of photosystem II (PSII) in hybrid bio-photoelectrochemical cells for conversion of solar energy to electrical current is hampered by PSII's narrow absorption cross-section and the generally poor electrical connection between isolated complex and different anode materials. Here, we merge isolated market-grade spinach PSII with 25 nm cystamine-2,6-dichlorobenzoquinone (cys-DCBQ) modified Au-nanoparticles (PSII–AuNP Cys-DCBQ ) to obtain one of the highest reported photocurrent values to date (35 mA cm −2 mg −1 chlorophyll), retaining the native oxygen evolution properties of PSII. More than 80% of the PSII in solution assembles stably onto the AuNP Cys-DCBQ . Spectroscopic studies show strong functional association in these hybrid particles. Mechanistic investigations reveal a dual role of the quinone-modified AuNPs, harvesting and transference of the excitation energy to PSII (resulting in ∼10-fold enhancement of anodic photocurrent in the 500–550 nm irradiation range) and simultaneously improving the electron transfer from PSII into the graphite anode (by almost 6-fold over the entire visible range of light).

    Abstract: Theodor Buchmann, better known as eodore Bibliander (1505-64), was Zwingli's immediate successor to the chair of Professor of Old Testament at the theological school in Zurich. An ardent orientalist, who was the first to edit a Latin translation of the Koran and a professed Hebraist, Bibliander could boast a well-articulated theology based on and around the knowledge of languages in general and of Hebrew in particular. In light of the contemporary prevalent notions of harmonia linguarum and concordia mundi, Bibliander sought to promote the study of Hebrew as an essential means to achieving a universal salvation. His treatise, De ratione omnium linguarum et literarum (Zurich, 1548), dedicated to the exposition of the said universalist theology, is the subject of this article. A full annotated translation of the De ratione communi is due to appear in the new series Corpus Reformatorum Minorum (Droz, Geneva).
