AbstractThe performance of organic photovoltaics (OPVs) has rapidly improved over the past years. Recent work in material design has primarily focused on developing near‐infrared nonfullerene acceptors with broadening absorption that pair with commercialized donor polymers; in the meanwhile, the influence of the morphology of the blend film and the energy level alignment on the efficiency of charge separation needs to be synthetically considered. Herein, the selection rule of the donor/acceptor blend is demonstrated by rationally considering the molecular interaction and energy level alignment, and highly efficient OPV devices using both‐fluorinated or both‐nonfluorinated donor/acceptor blends are realized. With the enlarged absorption, ideal morphology, and efficient charge transfer, the devices based on the PBDB‐T‐F/Y1‐4F blend and PBDB‐T‐F/Y6 exhibit champion power conversion efficiencies as high as 14.8% and 15.9%, respectively.

AbstractFlexible strain sensors have captured a lot of attention since first being proposed. Most studies are focused on adopting new materials or developing novel structures to detect strain, temperature, and even to realize multifunction. The reliability of flexible strain sensors in harsh environments such as at low and high temperatures, however, has so far received little attention because traditional bendable or stretchable substrates, including polyethylene terephthalate, polyimide, polydimethylsiloxane, paper, silk, and cotton, cannot withstand high temperature. The poor thermostability limits their potential applications in harsh conditions such as in interstellar probes, polar exploration, petrochemical, and metal smelting. Here, a heat‐resisting flexible strain sensor is shown, consists of a BaNb0.5Ti0.5O3 film on top of a 4.5 µm thick mica substrate. The device exhibits excellent thermal stability in a wide temperature range from 20 to 773.15 K. Owing to the ultrathin mica substrate and low resistance, the device demonstrates low power consumption (0.96 µW cm−2), is lightweight (2.06 g cm−3), together with having high stability over 5000 bending cycles. This work opens a path for pressure sensors applying ceramic materials that can be used from an ultralow to a high temperature.

Published: September 2019

AbstractMetasurfaces provide an unprecedented capability in manipulating electromagnetic waves. In this work, a millimeter‐wave (mmW) digital coding metasurface based on nematic liquid crystals (NLCs) is proposed and realized. By tuning the bias voltage loaded on the NLCs, the effective permittivity of the NLCs substrate is changed, thus providing different reflection phases. As a proof of concept, mmW beam splitting and mmW beam steering at mmW frequencies are demonstrated using a single metasurface platform. The experimental results are in good agreement with numerical simulations. The proposed digital coding metasurfaces have promising applications on planar mmW devices, such as multi‐beam antennas, beam‐scanning antennas, and wave controllers.

Published: September 2019

AbstractThe fast and reversible switching of plasmonic color holds great promise for many applications, while its realization has been mainly limited to solution phases, achieving solid‐state plasmonic color‐switching has remained a significant challenge owing to the lack of strategies in dynamically controlling the nanoparticle separation and their plasmonic coupling. Herein, we report a novel strategy to fabricate plasmonic color‐switchable silver nanoparticle (AgNP) films. Using poly(acrylic acid) (PAA) as the capping ligand and sodium borate as the salt, the borate hydrolyzes rapidly in response to moisture and produces OH− ions, which subsequently deprotonate the PAA on AgNPs, change the surface charge, and enable reversible tuning of the plasmonic coupling among adjacent AgNPs to exhibit plasmonic color‐switching. Such plasmonic films can be printed as high‐resolution invisible patterns, which can be readily revealed with high contrast by exposure to trace amounts of water vapor.
Hoarding: A multifactorial understanding
Authors: Akhtar Salman 
Published: September 2019

AbstractThe syndrome of hoarding has remained largely unaddressed by psychoanalysts. This is because grotesque forms of it do not appear at the clinician's door and the public focus on such gross pathology draws attention away from the subtler forms of hoarding in our patients. This paper delineates a thorough phenomenological profile of the hoarding disorder, distinguishing it from collecting and from obsessive–compulsive disorder with which it is frequently confused. It traces the phylogenetic basis of hoarding to animal survival techniques, the sociogenetic basis of the producers' induction of false needs in consumers, and ontogenetic basis to object‐hunger consequent upon childhood loss. The paper recommends a large‐hearted differential therapeutics to help individuals suffering from this syndrome.

AbstractThe following study was done to assess the glucose utilizing efficiency of Indoloquinoxaline derivative incorporated keratin nanoparticles (NPs) in 3T3‐L1 adipocytes. Indoloquinoxaline derivative had wide range of biological activities including antidiabetic activity. In this view, Indoloquinoxaline moiety containing N, N‐dimethyl (3‐fluoro‐6H‐indolo [3,2‐b] quinoxalin‐6‐yl) methanamine compound was designed and synthesized, and further it is incorporated into keratin nanoparticles. The formulated NPs, drug entrapment efficiency, releasing capacity, stability, and physicochemical properties were characterized by various spectral analyzer and obtained results of characterizations were confirmed the properties of NPs. The analysis of mechanism underlying the glucose utilization of NPs was examined through molecular docking with identified target, and observed in silico study reports shown strong interaction of NPs in the binding pockets of AMPK and PTP1B. Based on the in silico screening, the formulated NPs was performed for in vitro cellular viability and glucose uptake studies on 3T3‐L1 adipocytes. Interestingly, 40 μg of NPs displayed 78.2 ± 2.76% cellular viability, and no cell death was observed at lower concentrations. Further, the concentration dependent glucose utilization was observed at different concentrations of NPs in 3T3‐L1 adipocytes. The results of NPs (40 μg) on glucose utilization have revealed eminent result 58.56 ± 4.54% compared to that of Metformin (10 μM) and Insulin (10 μM). The identified results clearly indicated that Indoloquinoxaline derivative incorporated keratin NPs significantly increased glucose utilization efficiency and protect the cells against the insulin resistance.
Reflecting on Maltese school‐based counselling practices: An autoethnographic collaborative writing project

Published: September 2019

AbstractMaltese counsellors working in schools are, at times, just making ends meet due to lack of human resources and work schedules. ‘Why do our students/children have to repeat the same story to so many professionals?’ teachers/parents angrily query. This autoethnographic study voices our professional experiences as authors and participants. This empowers us to be advocates for our young clients. Collaborative autoethnography (CAE) methodology best fits our research question as we ‘seek to discover and systemically analyze (graphy) personal experience (auto)…understand cultural experience (ethno)’ (Ellis, Adams, & Brochner, 2011, p. 273). Our writing and reflections conclude that best practices include counsellors who work, at least, in pairs within transdisciplinary teams at one school for cycles of five years, with clarity of roles across professionals.

Published: September 2019

AbstractThe progression of diabetic cardiomyopathy is related to cardiomyocyte dysfunction and apoptosis. Our previous studies showed that asporin (ASPN) was significantly increased in the myocardium of db/db mice through proteomics, and grape seed procyanidin B2 (GSPB2) significantly inhibited the expression of ASPN in the heart of db/db mice. We report here that ASPN played a critical role in glycated low‐density lipoproteins (gly‐LDL) induced‐cardiomyocyte apoptosis. We found that gly‐LDL upregulated ASPN expression. ASPN increased H9C2 cardiomyocyte apoptosis with down‐regulation of Bcl‐2, upregulation of transforming growth factor‐β1, Bax, collagen III, fibronectin, and phosphorylation of smad2 and smad3. However, GSPB2 treatment reversed ASPN‐induced impairments in H9C2 cardiomyocytes. These results provide evidence for the cardioprotective action of GSPB2 against ASPN injury, and thus suggest a new target for fighting against diabetic cardiomyopathy.

AbstractObjectivesWe sought to evaluate mortality predictors and the role of new‐generation drug‐eluting stents (NG‐DES) in stent thrombosis (ST) management.BackgroundNo data are available regarding the outcome of patients with ST after interventional management that includes exclusively NG‐DES.MethodsPatients with definite ST of DES or BMS who underwent urgent/emergent angiography between 2015 and 2018 at our institution were considered for the study. After excluding patients who achieved TIMI‐flow<2 after intervention or received an old‐generation stent, 131 patients were included. Management classification was stent or non‐stent treatment (medical management, thromboaspiration, balloon‐angioplasty). Follow‐up was performed to document all‐cause death (ACD) and target‐lesion‐revascularization (TLR) that was used for censorship.ResultsMode of presentation was STEMI in 88% and UA/NSTEMI in 12%. Type of ST was early, late, and very late in 11, 4, and 85%, respectively. Eighty four patients received stent and 47 non‐stent treatment. After 926 ± 34 days, 21 ACDs, 7 TLRs and no cases of definite, recurrent ST were observed. Univariate predictors of in‐hospital mortality were LVEF and presentation with shock or cardiac arrest. For patients discharged alive, non‐stent treatment (HR 4.2, p = .01), TIMI‐2 flow (HR 7.4, p = .002) and GFR < 60 mL/min (HR 3.8, p = .01) were independent predictors of ACD. The stent‐treatment group had significantly better ACD‐free survival after discharge, both unadjusted (p = .022) and adjusted (p = .018).ConclusionsAfter ST management, different predictors were observed for in‐hospital mortality and mortality in patients discharged alive. The better outcome with NG‐DES treatment is a novel observation, warranting further studies to elucidate if it is associated with stent‐related or patient‐related factors.
S‐Scheme Heterojunction TiO2/CdS Nanocomposite Nanofiber as H2‐Production Photocatalyst

Published: September 2019

AbstractOne‐dimensional (1D) nanostructured photocatalyst is a promising candidate for hydrogen (H2) generation, which can be used to deal with the energy crisis. Herein, novel 1D TiO2/CdS well‐hybridized nanofibers (NFs) were synthesized via in situ electrospinning method. These 1D hybrid NFs showed a high H2‐production rate of 2.32 mmol h−1 g−1 with an apparent quantum efficiency of 10.14 %, which was 35‐fold higher than that of pristine TiO2 NFs. X‐ray photoelectron spectroscopy (XPS) analysis and density functional theory calculation implied that the electrons transferred from CdS to TiO2 upon hybridization and created an internal electric field (IEF) pointing from CdS to TiO2. This IEF drove the photoexcited electrons in TiO2 to transfer toward CdS upon light irradiation as revealed by in situ irradiated XPS analysis, suggesting that a step‐scheme (S‐scheme) heterojunction was formed in the TiO2/CdS nanohybrids and greatly promoted the separation of electron‐hole pairs to foster efficient H2 photogeneration. The significant enhancement of photocatalytic activity was also benefited from the easy transfer for electrons in the 1D well‐distributed nanostructure of nanohybrids. This work presents a method for in situ preparing well‐distributed 1D NFs with high photocatalytic activity for H2 production via the S‐scheme pathways.
New Insights in Frustrated Lewis Pair Chemistry with Azides

Published: September 2019

AbstractThe geminal frustrated Lewis pair (FLP) tBu2PCH2BPh2 (1) reacts with phenyl‐, mesityl‐, and tert‐butyl azide affording, respectively, six, five, and four‐membered rings as isolable products. DFT calculations revealed that the formation of all products proceeds via the six‐membered ring structure, which is thermally stable with an N‐phenyl group, but rearranges when sterically more encumbered Mes−N3 and tBu−N3 are used. The reaction of 1 with Me3Si−N3 is believed to follow the same course, yet subsequent N2 elimination occurs to afford a four‐membered heterocycle (5), which can be considered as a formal FLP‐trimethylsilylnitrene adduct. Compound 5 reacts with hydrochloric acid or tetramethylammonium fluoride and showed frustrated Lewis pair reactivity towards phenylisocyanate.

Published: September 2019

AbstractThe [4+2] cycloaddition of 2‐(2′‐pyridyl)‐4,6‐diphenyl‐λ3‐phosphinine with the highly reactive dienophile hexafluoro‐2‐butyne has been studied and the first pyridyl‐functionalized 1‐phosphabarrelene was obtained and structurally characterized. Although monodentate CF3‐1‐phosphabarrelenes show only a poor coordination ability, the chelating nature of the novel P,N‐hybrid ligand gives access to various transition‐metal complexes. Upon irradiation with UV light, the pyridyl‐functionalized 1‐phosphabarrelene undergoes a rather selective di‐π‐methane rearrangement in the coordination sphere of the metal center, leading to the formation of a complex based on a hitherto unknown pyridyl‐functionalized 5‐phosphasemibullvalene derivative. DFT calculations provide first insights into the mechanism of this reaction.
Understanding the Localization of Berylliosis: Interaction of Be2+ with Carbohydrates and Related Biomimetic Ligands
Authors: Müller Matthias , Buchner Magnus R. 
Published: September 2019

AbstractThe interplay of metal ions with polysaccharides is important for the immune recognition in the lung. Due to the localization of beryllium associated diseases to the lung, it is likely that beryllium carbohydrate complexes play a vital role for the development of berylliosis. Herein, we present a detailed study on the interaction of Be2+ ions with fructose and glucose as well as simpler biomimetic ligands, which emulate binding motives of saccharides. Through NMR and IR spectroscopy as well as single‐crystal X‐ray diffraction, complemented by competition reactions we were able to determine a distinctive trend in the binding affinity of these ligands. This suggests that under physiological conditions beryllium ions are only bound irreversibly in glycoproteins or polysaccharides if a quasi ideal tetrahedral environment and κ4‐coordination is provided by the respective biomolecule. Furthermore, Lewis acid induced conversions of the ligands and an extreme increase in the Brønstedt acidity of the present OH‐groups imply that upon enclosure of Be2+, alterations may be induced by the metal ion in glycoproteins or polysaccharides. In addition the frequent formation of Be‐O‐heterocycles indicates that multinuclear beryllium compounds might be the actual trigger of berylliosis. This investigation on beryllium coordination chemistry was supplemented by binding studies of selected biomimetic ligands with Al3+, Zn2+, Mg2+, and Li+, which revealed that none of these beryllium related ions was tetrahedrally coordinated under the give conditions. Therefore, studies on the metabolization of beryllium compounds cannot be performed with other hard cations as a substitute for the hazardous Be2+.

AbstractHerein, an oxidization reaction of enones with a CuII complex that leads to a new type of regioselective [3+2] cycloaddition is reported. Highly functionalized cyclopentenes and spirocyclic compounds are obtained in moderate‐to‐good yields. This cycloaddition reaction occurred through the formation of γ‐enone radicals, providing a rarely explored reactivity pattern for enones.
Effect of Rotor Disc Diameter on Holdup, Axial Dispersion and Droplet Size in a Taylor‐Couette Disc Contactor
Authors: Grafschafter Annika , Siebenhofer Matthäus 
Published: September 2019

AbstractApplication of liquid‐liquid extraction is on a steady rise. Although there are considerable designs of extraction devices, equipment design and optimization is still on the research agenda. Utilization in the biorefinery industry or metallurgy requires robust technologies and equipment. The simple design and stable operation performance of the Taylor‐Couette disc contactor suffices the technical needs for these harsh operation conditions. The effect of different rotor disc diameter on the dispersed phase holdup, axial dispersion, and droplet size was investigated. It was shown that with smaller rotor disc diameter stable operation is still feasible but higher axial backmixing has to be expected.
