Recent Advances in the Selective Transport and Recovery of Metal Ions using Polymer Inclusion Membranes
Authors: Wang Baoying , Wang Yaoming , Xu Tongwen 
Published: October 2023

AbstractPolymer inclusion membranes (PIMs) have gained significant attention in the field of metal separation and recovery due to their high selectivity, long service life, high stability, flexible design and low cost. Over the past 10 years, interest around PIMs has increased considerably; hence, the number of research papers has grown exponentially. This review provides the preparation methods and composition of PIMs, presents an overview of studies on PIMs reported since 2012, and discusses the relationship between the physicochemical properties of different types of membrane components and the microstructure, selectivity, transport performance and stability of prepared PIMs. This review also elucidates the metal transport mechanism at the interface and interior of PIMs and summarizes the modification and separation intensification methods of PIMs. Additionally, the structure and stability of PIM relative to other liquid membranes are also discussed. Finally, the existing challenges and perspectives of PIMs in the field of metal separation and recovery are proposed and highlighted. Notably, the need for highly selective and low‐cost carriers, a deeper understanding of membrane microstructure and separation mechanisms, and strategies for promoting widespread adoption of polymer inclusion membrane‐electrodialysis technology deserve particular consideration, which are of guiding significance for accelerating the industrialization process of PIMs.

AbstractControlling the handedness and absorptive characteristics of chiral materials is essential for exploring new advances in the field of chiral sensors and catalysts. The deliberate architecture of the building blocks and their self‐assembly process are critical factors for fabricating chirally active structures from achiral nanoscale components. Herein, the fabrication of multicomponent gel structures comprising magnetoplasmonic core–shell Au@FexOy nanowires embedded in a macroscopic titania nanocrystal network is demonstrated, which shows broadband absorption covering the ultraviolet–visible light spectrum while maintaining excellent porosity in the aerogel state. The effect of externally applied helical magnetic field is exploited to induce self‐assembly of the magnetoplasmonic nanowires into chirally active superstructures. Furthermore, a second vector of symmetry is observed when the chiral hydrogel unit is rotated up to 45° around the z‐axis perpendicular to the light path, in which the measured circular dichroism intensity is modulated up to ±102% compared to those at 0°. This study serves as a concept of designing optically active chiral 3D superstructures, applicable to optical filters, sensing devices, and chiral photocatalysts.

AbstractAlthough the MAPK/MEK/ERK pathway is prevalently activated in colorectal cancer (CRC), MEK/ERK inhibitors show limited efficiency in clinic. As a downstream target of MAPK, ELK4 is thought to work primarily by forming a complex with SRF. Whether ELK4 can serve as a potential therapeutic target is unclear and the transcriptional regulatory mechanism has not been systemically analyzed. Here, it is shown that ELK4 promotes CRC tumorigenesis. Integrated genomics‐ and proteomics‐based approaches identified SP1 and SP3, instead of SRF, as cooperative functional partners of ELK4 at genome‐wide level in CRC. Serum‐induced phosphorylation of ELK4 by MAPKs facilitated its interaction with SP1/SP3. The pathological neoangiogenic factor LRG1 is identified as a direct target of the ELK4‐SP1/SP3 complex. Furthermore, targeting the ELK4‐SP1/SP3 complex by combination treatment with MEK/ERK inhibitor and the relatively specific SP1 inhibitor mithramycin A (MMA) elicited a synergistic antitumor effect on CRC. Clinically, ELK4 is a marker of poor prognosis in CRC. A 9‐gene prognostic model based on the ELK4‐SP1/3 complex‐regulated gene set showed robust prognostic accuracy. The results demonstrate that ELK4 cooperates with SP1 and SP3 to transcriptionally regulate LRG1 to promote CRC tumorigenesis in an SRF‐independent manner, identifying the ELK4‐SP1/SP3 complex as a potential target for rational combination therapy.
Synthesis of α‐Branched Enones via Chloroacylation of Terminal Alkenes
Authors: Kim Jungwon , Müller Sven , Ritter Tobias 
Published: October 2023

AbstractHere, we show the conversion of unactivated alkenes into α‐branched enones via regioselective chloroacylation with acyl chlorides. The method relies upon the initial in situ generation of chlorine radicals directly from the acyl chloride precursor under cooperative nickel/photoredox catalysis. Subsequent HCl elimination provides enones and α,β‐unsaturated esters that are not accessible via the conventional acylation approaches that provide the other, linear constitutional isomer.
Controllable Topological Transformations of 818 Molecular Metalla‐knots by Oxidation of Thiazole‐Based Ligands
Authors: Zhang Hai‐Ning , Jin Guo‐Xin 
Published: October 2023

AbstractBy exploiting coordination‐driven self‐assembly, high yields of two 818 molecular metalla‐knots could be obtained using a thiazole‐moiety‐containing asymmetric dipyridyl ligand 2‐(pyridin‐4‐yl)‐5‐(pyridin‐4‐ylethynyl)benzo[d]thiazole (L1), as confirmed using X‐ray crystallographic analysis, electrospray ionization‐time‐of‐flight/mass spectrometry (ESI‐TOF/MS), and detailed liquid‐state nuclear magnetic resonance (NMR) spectroscopy. To modulate the self‐assembled structures, m‐chloroperbenzoic acid (m‐CPBA) was utilized to oxidize thiazole‐based ligand L1 to N‐thiazole‐oxide‐based ligand 2‐(pyridin‐4‐yl)‐5‐(pyridin‐4‐ylethynyl)benzo[d]thiazole 3‐oxide (L2), which enabled the selective construction of the corresponding tetranuclear macrocycles. Notably, two molecular metalla‐knots could be topologically transformed from 818 knots to simple monocycles because the L1 alkyne bond was inert toward m‐CPBA, as confirmed by liquid‐state NMR spectroscopy, ESI‐TOF/MS, and elemental analysis.

AbstractPhotocatalytic water splitting is a simple means of converting solar energy into storable hydrogen energy. Narrow‐band gap oxysulfide photocatalysts have attracted much attention in this regard owing to the significant visible‐light absorption and relatively high stability of these compounds. However, existing materials suffer from low efficiencies due to difficulties in synthesizing these oxysulfides with suitable degrees of crystallinity and particle sizes, and in constructing effective reaction sites. The present work demonstrates the production of a Gd2Ti2O5S2 (λ<650 nm) photocatalyst capable of efficiently driving photocatalytic reactions. Single‐crystalline, plate‐like Gd2Ti2O5S2 particles with atomically ordered surfaces were synthesized by flux and chemical etching methods. Ultrafine Pt‐IrO2 cocatalyst particles that promoted hydrogen (H2) and oxygen (O2) evolution reactions were subsequently loaded on the Gd2Ti2O5S2 while ensuring an intimate contact by employing a microwave‐heating technique. The optimized Gd2Ti2O5S2 was found to evolve H2 from an aqueous methanol solution with a remarkable apparent quantum efficiency of 30 % at 420 nm. This material was also stable during O2 evolution in the presence of a sacrificial reagent. The results presented herein demonstrates a highly efficient narrow‐band gap oxysulfide photocatalyst with potential applications in practical solar hydrogen production.

AbstractIn topological materials, shielding of bulk and surface states by crystalline symmetries has provided hitherto unknown access to electronic states in condensed matter physics. Interestingly, photoexcited carriers relax on an ultrafast timescales, demonstrating large transient mobility that can be harnessed for the development of ultrafast optoelectronic devices. In addition, these devices are much more effective than topologically trivial systems because topological states are resilient to the corresponding symmetry‐invariant perturbations. By using optical pump probe measurements, the relaxation dynamics of a topologically nontrivial chiral single crystal, PtAl, is systematically described. Based on the experimental data on transient reflectivity and electronic structures, it is found that the carrier relaxation process involves both acoustic and optical phonons with oscillation frequencies of 0.06 and 2.94 THz, respectively, in picosecond time scale. PtAl with a space group ofP213 allows only one non‐zero susceptibility element, i.e.,d14, in second harmonic generation (SHG) with a large value of 468(1) pm V–1, which is significantly higher than that observed in standard GaAs(111) and ZnTe(110) crystals. The intensity dependence of the SHG signal in PtAl reveals a non‐perturbative origin. The present study on PtAl provides deeper insight into topological states that will be useful for ultrafast optoelectronic devices.

Published: October 2023

AbstractThe aims of this study were to investigate the heavy metal pollution status and distribution and to analyze the relationships among metal concentrations of different links in the dairy production chain. Chromium (Cr), arsenic (As), cadmium (Cd), lead (Pb), copper (Cu), and zinc (Zn) levels in water, fodder, milk, blood, hair, and feces samples collected from cows from five dairy farms in China were measured. The concentrations of Cr, As, Cd, Pb, Cu, and Zn were 4.61–11.11, 0.06–0.46, 0.17–0.29, 2.84–4.23, 4.11–7.72, and 7.23–19.91 mg/kg in silage; 12.72–40.85, 0.76–2.40, 0.05–0.16, 4.73–9.16, 44.14–78.46, and 4148.51–4845.20 μg/L in milk; 33.59–60.73, 0.09–3.57, 0.29–1.78, 20.14–39.20, 821.34–1007.45, and 2665.10–4929.95 μg/L in blood; 0.59–1.06, 0.02–0.09, 0.08–0.11, 1.70–2.09, 6.45–8.64, and 9.73–1.56 mg/kg in hair; 31.75–296.35, 0.33–5.96, 0.18–0.53, 3.35–9.06, 12.27–41.39, and 56.54–196.34 mg/kg in feces, respectively. The concentrations of heavy metals in hair were higher than those in the other samples and when combined with the results from the silage and tissue samples, we can assume that cow's hair can be used as a biological indicator for heavy metal contamination in the dairy production chain.
Increasing leisure‐item engagement in individuals with autism

Published: October 2023

AbstractThe goal of the current study was to increase functional engagement with multiple leisure items for five individuals with ASD, who had limited leisure item engagement (i.e., they engaged with only one leisure item, and after that item was restricted, they exhibited no functional engagement with alternative activities). Response restriction (RR) preference assessments were conducted to assess pre‐ and post‐training performance to determine if training was necessary and if performance maintained following training. A component analysis that involved progressively adding intervention components (prompting alone; prompting plus differential reinforcement of alternative behavior), and targeting simple engagement prior to functional engagement, was conducted. For all participants, the progressive treatment approach was effective in increasing functional engagement to criterion levels for all trained items. However, the effective training component(s) varied across participants and items. During the final post‐training RR assessment, functional engagement maintained with all trained items for all participants.
How market competition influences organizational performance: Mediation in the interplay of management accounting system, enterprise risk management, and organizational innovation performance
Authors: Nu Minh Quyen Le , Khuong Nguyen Vinh 
Published: October 2023

AbstractThe purpose of this study is to examine the relationship between organizational performance (OP) in Vietnam and market competition (MC), enterprise risk management (ERM), management accounting system (MAS), and organizational innovation performance (OIP). We surveyed 397 individuals working in the company to elucidate the link between these variables. Data from the multiple factor survey were analyzed using PLS‐SEM software to illustrate the link between MC, MAS, ERM, OIP, and OP. The findings demonstrate a favorable association between direct and intermediary variables to OP, as predicted. Additionally, the intermediary factors have beneficial effects that help businesses in developing effective strategies in a competitive market, generating revenues, and achieving their objectives. The research results of the study show that, in a highly competitive market, organizational innovation efficiency is the top priority of organizations. To achieve this, companies must continuously adapt to the demands of the market.

Published: October 2023

AbstractBackgroundPatients with lung cancer surgery often suffer pain after discharge. However, there is limited evidence to describe the pain experience from the qualitative investigation. This study was designed to describe the pain experience of lung cancer patients during home recovery after surgery and to provide evidence for developing pain management strategies.MethodsThis qualitative descriptive study recruited 35 patients who had received lung resection and were discharged by purposive sampling from May to July 2022. Mobile phone interviews were conducted to collect views on patients' pain experience after discharge. The interviews were audio‐recorded and converted verbatim into standard text, and the data were iteratively thematic analyzed.ResultsA thematic framework was identified for three themes: perception and impact of pain, coping styles for pain, and unmet needs for pain. Whether short or long‐term after discharge, patients complain that they suffer from different degrees and types of pain, causing them a “double burden” physically and mentally. The lack of knowledge about pain may lead them to adopt very different coping styles and desire professional continuous pain management.ConclusionsThis study may help clarify the status of pain problems that patients face after lung cancer surgery and provides multiple dimensions of pain assessment and management objectives for quantitative research. We call on medical staff to pay attention to patients' perspectives and related needs after discharge and formulate targeted management strategies to reduce pain and improve their quality of life.
Mindfulness meditation and countertransference in the therapeutic relationship: A small‐scale exploration of therapists' experiences using grounded theory methods
Authors: Millon Guy , Halewood Andrea 
Published: October 2023

AbstractBackgroundDifficulties with containing or processing emotions brought up in the countertransference response have long been understood as having the potential to cause a rupture in the therapeutic relationship, often with damaging results for the client. As increasing numbers of psychotherapists are becoming interested in mindfulness meditation, and as evidence is building to suggest that mindfulness meditation is an effective way of relating to one's thoughts and emotions in a non‐judgemental and non‐reactive fashion, the effect this may be having on the processing of countertransference material seems a worthy area of investigation.MethodThis study explores the countertransference experiences of five psychotherapists who practised mindfulness meditation, using semi‐structured interviews. Data were analysed using a grounded theory methodology.ResultsA tentative conceptual understanding of the data was developed, indicating that therapists who practised mindfulness meditation were relating to countertransferential responses with an observing stance, a compassionately curious attitude and a holding of emotion, which brings them into the present moment, resulting in the experience of a deeper therapeutic relationship.DiscussionThe implications for training and practice are discussed, through the potential of practising mindfulness to cultivate a therapeutic attitude towards countertransference responses.

AbstractBackgroundWhile studies have shown the advantages of computed tomography angiography (CTA) over transesophageal echocardiography (TEE) in left atrial appendage closure (LAAC) preprocedural planning for WATCHMAN™ legacy and FLX devices, there has been no reported long‐term data for this approach.ObjectivesWe sought to evaluate long‐term outcomes using CTA‐based preprocedural planning for LAAC using the WATCHMAN™ device.MethodsA prospective analysis of 231 consecutive patients who underwent LAAC in a single, large academic hospital in the United States was conducted over a 5‐year period. CTA‐guided preprocedural planning was performed in all. Procedural success, adverse events, length of procedure, number of devices used, and length of stay were evaluated. Rates of death, cerebral embolism, systemic embolism, and major and minor bleeding were recorded. Adjusted predicted stroke and major bleeding rates were derived from CHA2DS2‐Vasc and HAS‐BLED scores, respectively.ResultsFrom January 26, 2017, to November 23, 2021, 231 patients underwent LAAC with CTA preprocedural planning by two operating physicians. The mean age of patients was 76.5 ± 8.4. 59.7% of patients were male. Mean CHA2DS2VASc and HAS‐BLED scores were 4.5 ± 1.4 and 3.9 ± 0.9, respectively. All procedures were performed with intracardiac echo (100%). The procedural success rate was 99.1%. The CTA sizing strategy accurately predicted the implant size in 93.5% of patients. Mean number of devices used was 1.10 ± 0.3. Peri‐procedural complication rate was 2.2%. 6 patients were lost to follow‐up. Mean follow‐up was 608.94 days with a total of 377.04 patient years. Median follow‐up period of 368 days (interquartile range: 209–1067 days). There were 51 deaths from all causes (13.52 per 100 patient‐years), 10 cases of cerebral embolism (2.65 per 100 patient‐years), 2 cases of systemic embolism (0.53 per 100 patient‐years), 17 cases of major bleeding (4.50 per 100 patient‐years), and 31 cases of minor bleeding (8.2 per 100 patient‐years). All‐cause mortality at 1, 2, and 3 years was 12.7%, 20.9%, and 29.2%, respectively. CV event rates at 1, 2, and 3 years were 2.1%, 6.6%, and 10.5%, respectively.ConclusionsCTA‐based preprocedural planning is accurate in predicting device size for LAAC and associated with excellent clinical outcomes at 5 years.

Published: October 2023

AbstractWe present successful treatment of dissected thoracoabdominal aorta using combined thoracic endovascular aortic repair and transfemoral replacement of Amplatzer™ vascular plug in a 38‐year‐old patient. Computed tomography angiography revealed a false lumen from the left subclavian artery to the left common iliac trunk, with re‐entries connecting it to the true lumen of the aorta. We replaced the prosthetic endovascular graft just below the left subclavian artery to the top of the superior mesenteric artery. Amplatzer™ vascular plug was replaced below the diaphragm in a closed transfemoral procedure to prevent re‐entry. The patient was discharged in good condition and 2 years postoperation imaging showed complete pseudoaneurysm closure.
Reductive Coupling of a Diazoalkane Derivative Promoted by a Potassium Aluminyl and Elimination of Dinitrogen to Generate a Reactive Aluminium Ketimide

Published: October 2023

AbstractThe reaction of 9‐diazo‐9H‐fluorene (fluN2) with the potassium aluminyl K[Al(NON)] ([NON]2−=[O(SiMe2NDipp)2]2−, Dipp=2,6‐iPr2C6H3) affords K[Al(NON)(κN1,N3‐{(fluN2)2})] (1). Structural analysis shows a near planar 1,4‐di(9H‐fluoren‐9‐ylidene)tetraazadiide ligand that chelates to the aluminium. The thermally induced elimination of dinitrogen from 1 affords the neutral aluminium ketimide complex, Al(NON)(N=flu)(THF) (2) and the 1,2‐di(9H‐fluoren‐9‐yl)diazene dianion as the potassium salt, [K2(THF)3][fluN=Nflu] (3). The reaction of 2 with N,N’‐diisopropylcarbodiimide (iPrN=C=NiPr) affords the aluminium guanidinate complex, Al(NON){N(iPr)C(N=CMe2)N(CHflu)} (4), showing a rare example of reactivity at a metal ketimide ligand. Density functional theory (DFT) calculations have been used to examine the bonding in the newly formed [(fluN2)2]2− ligand in 1 and the ketimide bonding in 2. The mechanism leading to the formation of 4 has also been studied using this technique.

AbstractA simple sequential addition protocol for the reductive coupling of ketones and aldehydes by a potassium aluminyl grants access to unsymmetrical pinacolate derivatives. Isolation of an aluminium ketyl complex presents evidence for the accessibility of radical species. Product release from the aluminium centre was achieved using an iodosilane, forming the disilylated 1,2‐diol and a neutral aluminium iodide, thereby demonstrating the steps required to generate a closed synthetic cycle for pinacol (cross) coupling at an aluminyl anion.
Einfluss der Partikelgröße auf die Staubungsneigung von partikulären Recyclingbaustoffen
Authors: Teipel Ulrich , Schreiber Alex , Wolf Sebastian 
Published: October 2023

AbstractPartikuläre Recyclingbaustoffe weisen oft eine breite Partikelgrößenverteilung auf und neigen somit zur Staubentwicklung. Diese Staubfreisetzung in gasförmiger Umgebung ist in vielen Fällen unerwünscht, da sie oft mit einem Ressourcenverlust, einer Belastung der beteiligten Personen und der Umwelt verbunden ist. Im Rahmen dieser Arbeit wurden verschiedene mineralische Materialien mit unterschiedlicher Größenverteilung und identischem Feuchtegehalt auf ihre Staubungsneigung untersucht.
