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 ...

Impact of kilobar pressures on ultrafast triazene and thiacyanine photodynamics
Very short fluorescence lifetimes evidence ultrafast deactivation of photoexcited molecules. To unveil the underlying mechanism for two compounds exhibiting (sub)picosecond emission dynamics, we combine femtosecond fluorescence upconversion with high-pressure liquid-phase spectroscopy. For the triaz...

Growth of nanodroplets on a still microfiber under flow conditions
Surface droplets in the microscale are of great interest for their relevance in broad droplet-based technologies. Derived from the Ouzo effect, the solvent exchange process is a simple bottom-up approach to produce surface nano-/micro-droplets by the nucleation and growth mechanism. The oil oversatu...

Preparation and reactivity of half-sandwich dioxygen complexes of ruthenium
Dioxygen complexes [Ru(η5-C5Me5)(η2-O2){P(OEt)3}2]BPh4 (1) and [Ru(η5-C5Me5)(η2-O2)(PPh3){P(OR)3}]BPh4 (2, 3) [R = Me (2), Et (3)] were prepared by allowing chloro-complexes RuCl(η5-C5Me5)[P(OEt)3]2 and RuCl(η5-C5Me5)(PPh3)[P(OR)3] to react with air (1 atm) in the presence of NaBPh4. Substitution of...

Structural and homotop optimization of neutral Al–Si nanoclusters
The geometry and stability of aluminum–silicon alloys up to 13 atoms are investigated using electronic structure methods. The results agree well with available experimental data, while also predicting new potential candidates for detection. The exploration of the potential energy hypersurface of suc...

Towards Mapping Electrostatic Interactions between Kdo2-Lipid A and Cationic Antimicrobial Peptides via Ultraviolet Photodissociation Mass Spectrometry
Cationic antimicrobial peptides (CAMPs) have known to act as multi-modal weapons against Gram-negative bacteria. As a new approach to investigate the nature of the interactions between CAMPs and the surfaces of bacteria, native mass spectrometry and two MS/MS strategies (ultraviolet photodissociatio...

A novel 3-hydroxychromone fluorescence probe for hydrogen sulfide based on an excited-state intramolecular proton transfer mechanism
Hydrogen sulfide (H2S) is a signaling gasotransmitter that plays important roles in modulating the functions of different systems. We have designed and synthesized a 3-hydroxychromone-based fluorescence probe A for H2S detection. Probe A is based on a H2S-induced thiolysis reaction as well as an exc...
