Published: June 2023

Motherese has been studied particularly in its prosodic features. The scientific literature has underlined the importance of this type of communication on the infants’ vocal responsiveness. However, we still know little about the role of motherese on preterm infants’ vocal responsiveness. We intend to know the prosodic and communicative characteristics of motherese in preterm dyads and particularly to understand its relationship with the preterm infant’s vocal responsiveness. At NICU, mothers (N = 38) were asked to speak and to sing without words (humming) to their preterm infants in kangaroo care during five periods of three minutes alternating voice and silence, controlling the order effect (silence – speech or humming – silence – humming or speech – silence). A microanalytical study about prosodic and communicative/affectionate features of motherese was performed using ELAN, MAXQDA, and PRAAT software. According to results, tonal contours (sinusoidal, U-shaped and falling) and infants’ vocalizations seem to contribute for preterm dyads’ vocal modulation. A high use of phatic and conative functions, interrogative utterances, infants’ positive aspects, infants designated by affectionate words, and utterances connected with infants' needs were observed. This study contributed to explore the role of the communicative/affectionate and prosodic features of the motherese on preterm infants’ vocal responsiveness during the kangaroo care in NICU. Still, more studies are needed to deepen these preliminary results.

AbstractObjectiveNo efficacious treatments exist to improve or prolong bulbar functions of speech and swallowing in persons with amyotrophic lateral sclerosis (pALS). This study evaluated the short‐term impact of dextromethorphan/quinidine (DMQ) treatment on speech and swallowing function in pALS.MethodsThis was a cohort trial conducted between August 2019 to August 2021 in pALS with a confirmed diagnosis of probable‐definite ALS (El‐Escorial Criteria‐revisited) and bulbar impairment (ALS Functional Rating Scale score ≤ 10 and speaking rate ≤ 140 words per minute) who were DMQ naïve. Efficacy of DMQ was assessed via pre‐post change in the ALS Functional Rating Scale‐Revised bulbar subscale and validated speech and swallowing outcomes. Paired t‐tests, Fisher's exact, and χ2 tests were conducted with alpha at 0.05.ResultsTwenty‐eight pALS enrolled, and 24 participants completed the 28‐day trial of DMQ. A significant increase in ALSFRS‐R bulbar subscale score pre‐ (7.47 ± 1.98) to post‐ (8.39 ± 1.79) treatment was observed (mean difference: 0.92, 95% CI: 0.46–1.36, p < 0.001). Functional swallowing outcomes improved, with a reduction in unsafe (75% vs. 44%, p = 0.003) and inefficient swallowing (67% vs. 58%, p = 0.002); the relative speech event duration in a standard reading passage increased, indicating a greater duration of uninterrupted speech (mean difference: 0.33 s, 95% CI: 0.02–0.65, p = 0.035). No differences in diadochokinetic rate or speech intelligibility were observed (p > 0.05).InterpretationResults of this study provide preliminary evidence that DMQ pharmacologic intervention may have the potential to improve or maintain bulbar function in pALS.

Published: June 2023

AbstractSilicon (Si) is becoming one of the most promising candidates for lithium‐ion batteries (LIBs) owing to its high theoretical capacity, ultralow lithiation/delithiation voltage, non‐flammability, abundant natural reserves, etc. However, Si particles undergo violent volume expansion/contraction during the charge/discharge cycles, resulting in a series of serious problems such as Si particle pulverization, solid electrolyte interphase film overgrowth, and electrode structure collapse, which severely hinders the application of silicon‐based LIBs. Herein, a composite binder crosslinked by polyacrylic acid and p‐toluene sulfonic acid protonated polyaniline is proposed to improve the electrochemical performance of Si‐based anodes. The cross‐linked composite binder processes 3D networks, fast self‐healing features, and excellent mechanical strength, which can alleviate the damage caused by the expansion of Si particles to the electrodes and protect the structural integrity of the Si‐based electrodes. As a result, the Si‐based anodes with the composite binder present excellent cycle stability (2092.9 mAh g−1 after 300 cycles at 400 mA g−1). In addition, the novel binder reveals well compatibility with commercial Si microparticles. More importantly, the self‐healing Si anode is firstly equipped in an all‐solid‐LIB with solvate ionic liquid‐based quasi‐solid electrolyte and shows excellent cycling stability as well as rate capability.
Template Pore Size and A‐Site Cation Management Dictate Luminescence Efficiency, Stability, and Wavelength in Confined Perovskite Nanostructures

Published: June 2023

AbstractA‐site cation composition is a useful lever in optimizing the photophysical properties and stability of metal halide perovskites (MHPs). Independent of this, straightforward preparative routes to MHP nanostructures that employ a single solid‐state template with modest thermal requirements are also in demand. Here both strategies are employed in the fabrication and evaluation of luminescence properties of mixed formamidinium/cesium (CsxFA1−xPbBr3) and methylammonium/cesium (CsxMA1−xPbBr3) nanostructures formed within confining mesoporous silica of 4 and 7 nm average pore diameters. Use of such small‐pore oxide‐terminated templates produce perovskite nanostructures in the strongly confined regime, with broadly tunable emission from green to sky blue. It is found that the smallest nanostructures that are formamidinium rich exhibit the largest photoluminescence quantum efficiency values, but such values diminish by more than 50% in a 10 day period. In contrast, the same nanostructures formed within a 7 nm porous template retain their efficiency values over the same time window. The likely origins of this size‐dependent behavior are discussed in terms of pore‐size‐dependent capillary forces. Such routes may ultimately lead to improved light‐emitting diode designs composed of controlled quantum‐confined perovskites of greater intrinsic stability than other emitters such as ligand‐based colloidal nanocrystals.
Plasmonic Nanopyramid Array Enhancing Luminescence of MoS2 Investigated by Cathodoluminescence

Published: June 2023

AbstractTransition metal dichalcogenides (TMDs) like molybdenum disulfide (MoS2) have unique optical properties such as strong luminescence and a tunable bandgap. However, the small interaction distance due to the atomically thin nature of these materials is a limitation for applications. In this study, a significant enhancement of the A‐ and B‐exciton emission in MoS2 flakes through coupling with plasmonic Au nano‐pyramid arrays fabricated by a colloidal lithography technique is reported. This study experimentally maps local emission enhancement from the structure with a nanometer spatial resolution by cathodoluminescence (CL) technique. Strongly enhanced emission intensity within the MoS2‐Au pyramids is achieved due to the localized surface plasmon resonance confined in nano‐pyramids and its interaction with the periodicity‐based resonance of the array structure. The results provide an approach to significantly improve the luminescence intensity of MoS2 through optical interaction with the local plasmonic field, which is promising for applications in optoelectronic devices and nanophotonics.
Uncovering the Reactivity of Cobalt‐Catalyst Towards Regioselective Hydroarylation of 1,6‐Diyne via Weak‐Chelation Assisted C−H Bond Activation

Published: June 2023

AbstractHerein, we report the reactivity of cobalt(III)‐catalyst towards hydroarylative functionalization of 1,6‐diyne, which has never been explored before. The N‐aryl lactam is the prime substrate that undergoes sp2 C−H bond activation. C−Co(III) bond formation occurs through weakly coordinating lactam group. The reaction mechanism reveals the in‐situ formation of a six‐membered cobaltacycle which undergoes further functionalization with 1,6‐diyne. Also, radical quenching experiments suggest the involvement of the ionic pathway for this conversion. In addition, hydrogen scrambling and kinetic isotope experiments support the proposed mechanism. A wide range of electronically biased substrates and reacting partners work well with this method in a highly atom‐economical fashion.

Published: June 2023

AbstractIn dieser Arbeit berichten wir von der Synthese eines sterisch verzerrten Distibens ([4]2) und seiner den Übergansmetallen ähnelnden Reaktivität gegenüber den beiden bedeutenden Grundchemikalien H2 und Ethylen. Obwohl ein ungewöhnlich langer Sb=Sb‐Abstand und eine bemerkenswerte Verzerrung des Grundgerüstes im Festkörper vorliegen, zeigen NMR‐Daten, dass [4]2 auch in Lösung und bei höheren Temperaturen hauptsächlich als Dimer vorliegt. Es wird angenommen, dass die ungewöhnliche Reaktivität gegenüber H2 und Ethylen auf eine reversible Dissoziation von [4]2 in das instabile Stibiniden ([4]) zurückzuführen ist. Dies konnte mittels NMR‐Spektroskopie beobachtet werden.

Published: June 2023

AbstractChiral amines are broadly used compounds in pharmaceutical industry and organic synthesis, and reductive amination reactions have been the most appreciated methods for their syntheses. However, one‐step transfer hydrogenative direct asymmetric reductive amination (THDARA) that could expand the scope, simplify the operation and eliminate the use of additives has been challenging. In this work, based on the Xiao's racemic transfer hydrogenative reductive amination in 2010 and our recent work in novel chiral pyridine ligands, chiral half‐sandwich iridium catalysts were rationally designed and synthesized. Using the optimized catalyst and azeotropic mixture of formic acid and triethylamine as the hydrogen source, a broad range of α‐chiral (hetero)aryl amines, including various polar functional groups and heterocycles, were prepared in generally high yield and enantioselectivity under mild and operationally simple conditions. Density functional theory (DFT) calculation of the catalytically active Ir−H species and the key hydride transfer step supported the chiral pyridine‐induced stereospecific generation of the iridium center, and the enantioselection by taming the highly flexible key transition structure with multiple attractive non‐covalent interactions. This work introduced a type of effective chiral catalysts for simplified approach to medicinally important chiral amines, as well as a rare example of robust enantioselective transition‐metal catalysis.

Published: June 2023

AbstractIt is challenging to achieve stable and efficient radical emissions under ambient conditions. Herein, we present a rational design strategy to protect photoinduced carbonyl free radical emission through electrostatic interaction and spin delocalization effects. The host‐guest system is constructed from tricarbonyl‐substituted benzene molecules and a series of imidazolium ionic liquids as the guest and host, respectively, whereby the carbonyl anion radical emission can be in situ generated under the light irradiation and further stabilized by electrostatic interaction. More importantly, the anion species and the alkyl chain length of imidazolium ionic liquids show a noticeable effect on luminescence efficiency, with the highest radical emission efficiency is as high as 53.3 % after optimizing the imidazole ionic liquid's structure, which is about four times higher than the polymer‐protected radical system. Theoretical calculations confirm the synergistic effect of strong electrostatic interactions and that the spin delocalization effect significantly stabilizes the radical emission. Moreover, such a radical emission system also could be integrated with a fluorescent dye to induce multi‐color or even white light emission with reversible temperature‐responsive characteristics. The radical emission system can also be used to detect different amine compounds on the basis of the emission changes and photoactivation time.

AbstractSluggish oxygen evolution kinetics and serious charge recombination restrict the development of photoelectrochemical (PEC) water splitting. The advancement of novel metal–organic frameworks (MOFs) catalysts bears practical significance for improving PEC water splitting performance. Herein, a MOF glass catalyst through melting glass‐forming cobalt‐based zeolitic imidazolate framework (Co‐agZIF‐62) was introduced on various metal oxide (MO: Fe2O3, WO3 and BiVO4) semiconductor substrates coupled with NiO hole transport layer, constructing the integrated Co‐agZIF‐62/NiO/MO photoanodes. Owing to the excellent conductivity, stability and open active sites of MOF glass, Co‐agZIF‐62/NiO/MO photoanodes exhibit a significantly enhanced photoelectrochemical water oxidation activity and stability in comparison to pristine MO photoanodes. From experimental analyses and density functional theory calculations, Co‐agZIF‐62 can effectively promote charge transfer and separation, improve carrier mobility, accelerate the kinetics of oxygen evolution reaction (OER), and thus improve PEC performance. This MOF glass not only serves as an excellent OER cocatalyst on tunable photoelectrodes, but also enables promising opportunities for PEC devices for solar energy conversion.
