A new and smooth approach towards alkynylphosphine derivatives is described. It relies on the unprecedented catalytic coupling of secondary phosphine boranes with alkynyl bromides using the CuI/1,10-phenanthroline couple.

The authors describe a framework, based on the Ogden-Richards semiotic triangle, for understanding the relationship between the Unified Medical Language System (UMLS) and the source terminologies from which the UMLS derives its content. They pay particular attention to UMLS's Concept Unique Identifier (CUI) and the sense of "meaning" it represents as contrasted with the sense of "meaning" repre...

La teoria di Dirac dell’elettrone fa uso, come è noto, di una funzione d’onda a quattro componenti delle quali, quando si considerino movimenti lenti, due hanno valori trascurabili mentre le altre due obbediscono in prima approssimazione all’equazione di Schrödinger. In modo analogo una particella con momento angolare intrinseco s h 2π (s = 0, 12 , 1, 3 2 , . . .) è descritta nella meccanica qu...

Hole transport material (HTM) plays an important role in the efficiency and stability of perovskite solar cells (PSCs). Spiro-MeOTAD, the commonly used HTM, is costly and can be easily degraded by heat and moisture, thus offering hindrance to commercialize PSCs. There is dire need to find an alternate inorganic and stable HTM to exploit PSCs with their maximum capability. In this paper, a compr...

Two types of secondary building units of CuI (Cu2I2 and Cu4I4) were shown to generate 2D-coordination networks of (4,4)-topology (non-interpenetrated and interpenetrated) with exo-bidentate ligands that contain diamide as spacer.

CuI-Based Nonvolatile Memory In article number 2211022, Sung Hun Jin, and co-workers explore the light mediated resistive switching of CuI based, random-access memory device in terms enhancement scheme for reliability, current conduction mechanism via low temperature study. This potentially opens a new paradigm nonvolatile technologies with high density multibit data storage.

An efficient methodology for the synthesis of highly functionalized ellipticinium and ellipticine derivatives starting from the corresponding 2-bromocarbazoles via an AgOTf or CuI catalyzed electrophilic cyclization of 2-alkynyl-3-carbazolylaldimines is reported.
