Direct visualization of diffuse unoccupied molecular orbitals at a rubrene/graphite interface
Spectroscopic and nanoscale imaging investigations concerning the spatial extent of molecular orbitals at organic/substrate interfaces have been of intense interest to understand charge dynamics. Here, the spatial extent of unoccupied molecular orbitals of ultrathin rubrene [5,6,11,12-tetraphenyltet...

Stereoselective synthesis of 3-spiropiperidino indolenines via SN2-type ring opening of activated aziridines with 1H-indoles/Pd-catalyzed spirocyclization with propargyl carbonates
3-Spiropiperidino indolenines have been synthesized via novel Lewis acid-catalyzed SN2-type ring opening of activated aziridines with 1H-indoles followed by Pd-catalyzed dearomative spirocyclization with propargyl carbonates in up to 88% yields. The step and pot-economic transformation comprises seq...

Spontaneous separation of on-surface synthesized tris-helicenes into two-dimensional homochiral domains
The on-surface Ullmann coupling of 2,3-dibromo[4]helicene molecules is studied on Au(111) and Cu(111) surfaces. Bis-helicene and tris-helicene are identified with scanning tunnelling microscopy and X-ray photoelectron spectroscopy as reaction products. The produced star-shaped tris-helicenes self-as...

Electro-analytical investigation of potential induced degradation in mc-silicon solar cells: case of sodium ion induced inductive loop
Potential induced degradation of shunt type (PID-s) in multi-crystalline silicon (mc-Si) solar cells is becoming critical for performance reduction of solar panels in large scale photovoltaic (PV) power plants. In this article PID-s has been investigated by applying high voltage stress on mc-Si sola...

Large area efficient interface layer free monolithic perovskite/homo-junction-silicon tandem solar cell with over 20% efficiency
Monolithic perovskite/silicon tandem solar cells show great promise for further efficiency enhancement for current silicon photovoltaic technology. In general, an interface (tunnelling or recombination) layer is usually required for electrical contact between the top and the bottom cells, which incu...

Total Synthesis of the Proposed Structure of Talarolide A
The proposed structure of talarolide A, a cycloheptapeptide featuring a hydroxamate moiety within the peptide backbone, was successfully synthesized. An initial attempt to synthesize a linear peptide precursor containing a C-terminal N-benzyloxy glycine residue was problematic due to an an unreporte...

Redox-enhanced hemilability of the tris(tert-butoxy)siloxy ligand at cerium
The stabilizing effect of the tris(tert-butoxy)silyoxy ligand on cerium(IV) is revealed by electrochemical and computation methods as well as targeted redox chemistry. Ceric homoleptic complex Ce[OSi(OtBu)3]4 was obtained by the reaction of [Et4N]2[CeCl6] with NaOSi(OtBu)3 at ambient temperature in ...

Complex coacervation of natural sophorolipid bolaamphiphile micelles with cationic polyelectrolytes
Complex coacervation of polyelectrolytes with surfactant micelles is a promising system for a wide range of applications. However, the development of “green coacervates” from bio-based surfactants and biopolymers has not yet been explored. Herein, complex coacervation of micelles from a bolaform sop...

Arene-Tethered Silylene Ligand Enabling Reversible Dinitrogen Binding to Iron and Catalytic Silylation
The arene-tetherd silylene ligand L (L = PhC(tBuN)2SiCH2C(tBu)NAr, Ar = 2,6-iPr2C6H3) allowed the synthesis of the three-coordinate Fe(II) silylamido and piano-stool Fe(0) dinitrogen complexes LFe[N(SiMe3)2]2 (3) and LFe-N2 (4), which not only exhibit interesting bonding but also enabled catalytic s...

Precursor-mediated synthesis of Cu2?xSe nanoparticles and their composites with TiO2 for improved photocatalysis
The direct synthesis of copper selenide nanoparticles from the reaction of ditertiarybutyl selenide tBu2Se with copper(ii) trifluoroacetate Cu(TFA)2 under mild conditions is reported. The isolation of a molecular species during the course of this reaction, established as [Cu2(TFA)2(tBu2Se)3], by spe...

Intramolecular Strong Electronic Coupling in a Discretely H-Aggregated Phthalocyanine Dimer Connected with a Rigid Linker
Preparation of an accurate assembly of phthalocyanines is rather difficult because of the high aggregation property of phthalocyanines. In this study, a novel discrete phthalocyanine dimer was prepared in which the relative configuration of each component was tightly and accurately fixed in an H-agg...

Effects of Nd-modification on the activity and SO2 resistance of MnOx/TiO2 catalyst for low-temperature NH3-SCR
MnOx/TiO2 (MnTi) and Nd-modified MnOx/TiO2 (MnNdTi) were prepared via a coprecipitation method. The used samples were obtained by exposing the fresh catalysts to 50 ppm SO2 stream at 210 oC for 3 h and 6 h, respectively. Comparative investigations were performed on the fresh and used catalysts to id...

Developing near-infrared long-lasting phosphorescence of Yb3+ through medium: energy-transfer insight in novel material Zn1.98Li0.02P2O7:Yb3+
Near-infrared (NIR) long-lasting phosphorescence (LLP) phosphors have potential applications in biological and military fields. However, these phosphors are far from enough to satisfy demand. Herein, we report a series of novel LLP phosphors Zn1.98-xLi0.02P2O7:xYb3+ with strong NIR LLP. By investiga...

Biodegrabability of several antipsychotic drugs: manual and automatic assessment
The present work aims to assess the 5-days biochemical oxygen demand (BOD5) levels of several typical and atypical antipsychotic (AP) drugs to evaluate the biodegradability degree of them. Since the consumption of APs have seen a huge increase nowadays, the BOD5 could be a good parameter to evaluate...

Continuum of Covalent to Intermolecular Bonding in the Halogen-Bonded Complexes of 1,4-Diazabicyclo[2.2.2]octane with Bromine-Containing Electrophiles
A gradual change of Br···N bond lengths and strengths from the values typical for intermolecular associates to that characteristic of a covalent bond was observed in the series of the halogen-bonded complexes. This continuum reveals fundamental relationship between the limiting types of bonding and ...
