Published: March 2023

AbstractWhile functional materials with both light transmitting and electromagnetic shielding are highly desirable and have made rapid advancements, only very few of them meet the stringent electromagnetic interference (EMI) shielding criteria for optoelectronic systems. Achieving high optical transparency and superior EMI shielding in a broad frequency spectrum is a remaining challenge in both academic and industrial areas. Herein, a design strategy of shorted micro‐waveguides (SMWs) array to decouple the light transmission and EMI shielding is proposed and experimentally demonstrated. The array of SMWs, consisting of cutoff metallic micro‐waveguides and shorting indium tin oxide (ITO) continuous conductive film, exhibits high optical transmittance of 90.4% and superior EMI shielding effectiveness of 60.8 dB on average over ultra‐wide frequency spectrum (0.2–1.3 GHz & 1.7–18 GHz). Compared to previously reported works, an improvement of 17 dB in average shielding effectiveness is achieved under the same level of light transmission, and the shielding frequency spectrum is significantly expanded. The working principle is explained in depth and factors influencing the performance are investigated for design optimization. These outstanding properties enable the transparent shielding material based on SMWs to excel in future applications of EMI shielding for optoelectronic systems.

AbstractThe development of solid‐state proton conductors with high proton conductivity at low temperatures is crucial for the implementation of hydrogen‐based technologies for portable and automotive applications. Here, we report on the discovery of a new crystalline metal acid triphosphate, ZrH5(PO4)3 (ZP3), which exhibits record‐high proton conductivity of 0.5–3.1×10−2 S cm−1 in the range 25–110 °C in anhydrous conditions. This is the highest anhydrous proton conductivity ever reported in a crystalline solid proton conductor in the range 25–110 °C. Superprotonic conductivity in ZP3 is enabled by extended defective frustrated hydrogen bond chains, where the protons are dynamically disordered over two oxygen centers. The high proton conductivity and stability in anhydrous conditions make ZP3 an excellent candidate for innovative applications in fuel cells without the need for complex water management systems, and in other energy technologies requiring fast proton transfer.
Site‐Selective C−H Alkenylation of N‐Heteroarenes by Ligand‐Directed Co/Al and Co/Mg Cooperative Catalysis**
Authors: Saito Yuri , Kikuchi Jun , Wang Chen , Yoshikai Naohiko 
Published: March 2023

AbstractWe report herein the design and development of Co/Al and Co/Mg bimetallic catalysts, supported by a phosphine/secondary phosphine oxide (PSPO) bifunctional ligand, for the site‐selective C−H alkenylation of nitrogen‐containing heteroarenes with alkynes. These catalysts enable the alkenylation of pyridine, pyridone, and imidazo[1,2‐a]pyridine derivatives at the C−H site proximal to the Lewis basic nitrogen or oxygen atom, which represents a selectivity profile distinct from that of the previously developed cobalt‐diphosphine/aluminum catalyst. The alkenylated products were obtained in moderate to good yields using various heterocycles and differently substituted internal alkynes. Kinetic isotope effect experiments suggest the irreversibility of the C−H activation step, the relevance of which to the rate‐limiting step depends on the reaction conditions. Density functional theory calculations indicate that ligand‐to‐ligand hydrogen transfer is the common mechanism of C−H activation.
Type I Photosensitizer Targeting G‐Quadruplex RNA Elicits Augmented Immunity for Cancer Ablation

Published: March 2023

AbstractType I photodynamic therapy (PDT) represents a promising treatment modality for tumors with intrinsic hypoxia. However, type I photosensitizers (PSs), especially ones with near infrared (NIR) absorption, are limited and their efficacy needs improvement via new targeting tactics. We develop a NIR type I PS by engineering acridinium derived donor‐π‐acceptor systems. The PS exhibits an exclusive type I PDT mechanism due to effective intersystem crossing and disfavored energy transfer to O2, and shows selective binding to G‐quadruplexes (G4s) via hydrogen bonds identified by a molecular docking study. Moreover, it enables fluorogenic detection of G4s and efficient O2⋅− production in hypoxic conditions, leading to immunogenic cell death and substantial variations of gene expression in RNA sequencing. Our strategy demonstrates augmented antitumor immunity for effective ablation of immunogenic cold tumor, highlighting its potential of RNA‐targeted type I PDT in precision cancer therapy.
Generative systemic‐constructionist psychotherapy in the face of crisis in the context of armed violence in colombia: Case of MM, Montes de María – Department of Sucre
Authors: Sánchez‐Jiménez Maria Hilda 
Published: March 2023

AbstractThis article aims to show a process of systemic‐constructionist and generative therapy in the face of crisis situations experienced by MM. MM is a woman victim–survivor from the region of Los Montes de María in Colombia, a territory hard hit by armed violence between 1990 and 2008. Methodologically, the fragments presented are those that are repeated in three sessions. Psychotherapeutic work is a combination of dialogical and interactive resources, opportunities, and capacities that combine three kinds of time in MM's daily life. These are: first, the past of the violence; second, the present comprised of the presence of memories of violence, social and family interactions, together with psychiatric diagnoses; and third, the sense of a future based on the hope of reducing their suffering and taking action against the violence. Analysis and interpretation are hermeneutical constructions carried out throughout the psychotherapeutic process and in the midst of generative dialogues. On the one hand, the scientific and everyday knowledge that helps to process and transform the crisis is recognised. On the other hand, it shows a form of knowledge that distances itself from the parameters of science and positivist approaches. In conclusion, this article is an opportunity to question traditional positions within the field of mental health in the light of moments constructed with MM in the framework of systemic‐constructionist therapy, seen as a relational space where generative contexts are built.
The outside and family therapy: A perspective from the relational thinking of Gilles Deleuze
Authors: Argüello Rogelio 
Published: March 2023

AbstractThis article was inspired by a reflection on what unfolded with the COVID‐19 virus, especially how it brought to light the interconnectedness of individual and collective well‐being. This calls for a reassessment of the family therapy approach, which has traditionally focussed on the internal dynamics of the family to explain problems faced by individuals inside the family system without taking into account social, political and historical aspects. This approach, which is referred to in the article as ‘familialism,’ is challenged using the relational philosophy put forward by Gilles Deleuze and Félix Guattari, and a fresh viewpoint is also given from the concept of the ‘outside.’ This outside perspective seeks to prevent the family system from closing in on itself, allowing for the creation of open systems. By doing so, it is argued, it is possible to incorporate different elements of the social, political and historical order in therapeutic practice and prevent underestimating the complexity of the human experience.
Facile preparation of highly crystalline poly(L‐lactide) films with inversed wettability and their potential application in oil–water separation
Authors: Chen Li , Pang Xiujiang 
Published: March 2023

AbstractHighly crystallized poly(L‐lactide) (PLLA) films with enhanced hydrophobicity are easily prepared by casting PLLA solution into a poor solvent like isopropyl alcohol (IPA). The crystallinity of the PLLA film can be controlled by PLLA's concentration, the kind of poor solvent, and the volume ratio of poor solvent dichloromethane (DCM). Results show the addition of poor solvents obviously accelerate the crystallization of PLLA film and enhance the crystallinity up to 48.7%. A lower volume ratio of IPA/DCM at higher PLLA concentration as well as a higher volume ratio of IPA/DCM at lower PLLA concentration is conducive to raising the crystallinity of the PLLA film. In the meanwhile, microscopy observation and wettability tests confirm the PLLA films present multidimensional microstructure including fibrils, lamellas, and flower‐like stacks or spherulite‐like superstructure, and display high porosity as well as enhanced hydrophobicity. Despite the volume ratio of IPA/DCM, the PLLA films prepared at lower concentrations display higher crystallinity, porosity as well as hydrophobicity than those prepared at higher concentrations. The highly crystalline PLLA films with enhanced porosity and hydrophobicity are supposed to be applied in oil–water separation, and so forth.

Published: March 2023

AbstractOrganic light‐emitting diodes (OLEDs) using thermally activated delayed fluorescence (TADF) materials to sensitizing conventional fluorescence dopants (CFDs) have attracted intensive research interest due to the extraordinary device performances. Herein, a cyan luminogen (TCz‐BP‐SFAC) with TADF and aggregation‐enhanced emission (AEE) character is developed as a sensitizing host for CFDs. TCz‐BP‐SFAC owns excellent thermal and electrochemical stabilities, prefers horizontal dipole orientation and demonstrates violent delayed fluorescence with high photoluminescence quantum yields in neat and doped films. It exhibits preeminent electroluminescence (EL) performances with maximum external quantum efficiencies (ηexts) of 25.1% and 30.0% and very low efficiency roll‐offs. TCz‐BP‐SFAC also performs well as a sensitizing host for CFDs of different colors. When TCz‐BP‐SFAC sensitizing green emitter TTPA and orange emitter TBRB, the devices achieve high ηexts of 16.9% and 17.1% as well as very low efficiency roll‐offs of 2.4% and 1.2%, respectively. Moreover, TCz‐BP‐SFAC can serve as a sensitizing host for two‐color all‐fluorescence white OLEDs, resulting in high ηexts of ∼18% and very low efficiency roll‐offs of ∼5%. The outstanding EL performances predict the great potential of TCz‐BP‐SFAC as emitter and host in practical display and lighting devices.
Beyond conventional aqueous electrolytes: Recent developments in Li‐free “water‐in‐salt” electrolytes for supercapacitors
Authors: Kim Jongyoon , Lee Subin , Lee Dongwook , Yoo Seung Joon 
Published: March 2023

AbstractWater‐in‐salt electrolyte (WiSE) is an extremely high‐concentration aqueous solution where the salt outnumbers the solvent by weight and/or volume. Supercapacitors (SCs) incorporating lithium‐free WiSE are promising energy storage systems due to their wide electrochemical stability window (ESW), high‐ionic conductivity, low cost, and ecofriendliness. This review provides an overview of WiSE‐based SCs, focusing on physicochemical properties, recent progress, and prospects of non‐lithium WiSE‐based SCs. The mechanisms of how WiSEs exhibit expanded ESW, high‐ionic conductivity, and low‐temperature tolerance are elaborated. Then, we summarized the current strategies for the lithium‐free WiSE‐based SCs categorized by cations (Na+, K+, other metallic cations, and non‐metallic cations). In addition, the utilization of redox additives in WiSE‐based SCs is presented. Finally, current challenges and perspectives for the application of Li‐free WiSE into SCs are provided.

AbstractBackgroundChronic total occlusion (CTO) revascularization is a major source of radiation for both patients and physicians. Therefore, efforts to minimize radiation during CTO percutaneous coronary intervention (PCI) are highly encouraged.AimsTo evaluate the impact of an Ultra Low fluoroscopic Dose Protocol (ULDP), based on 3.75 frames per second for the fluoroscopy and 7.5 frames per second for the cine acquisition, during CTO PCI.MethodsOne hundred fifty consecutive patients who underwent CTO PCI were retrospectively enrolled. Eighty‐five underwent standard dose protocol (SDP) and 65 ULDP. Radiation exposure and acute clinical outcomes were compared between groups. Results were stratified according to lesion complexity.ResultsPatients undergoing ULDP, as compared to those undergoing SDP, showed a significant reduction of kerma area product, both for simple lesions (6861.0 vs. 13236.0 mGy × cm2; p = 0.014) and complex lesions (CL) (8865.0 vs. 16618.0 mGy × cm2; p < 0.001). Similarly, Air Kerma (AK) was lower when ULDP was used (1222.5 vs. 2015.0 cGy in SL, p = 0.134; 1499.0 vs. 2794.0 cGy in CL, p < 0.001). No significant differences were reported regarding procedural success and in‐hospital major adverse cardiovascular events between groups. Notably, there was not any crossover from ULDO to SDP due to poor quality images. Interestingly, fluoroscopy time, procedural time and contrast volume was significantly lower in patients undergoing ULDP only for CLs.ConclusionsULDP significantly reduces radiation exposure in the setting of high complexity procedures such as CTO PCI. This reduction seemed to be greater with increased procedural complexity and did not impact acute success or adverse clinical events.
Degradation Mechanisms of Platinum Group Metal‐Free Oxygen Reduction Reaction Catalyst based on Iron Phthalocyanine
Authors: Honig Hilah C. , Elbaz Lior 
Published: March 2023

AbstractPlatinum group metal‐free catalysts have been considered the most promising alternative for platinum‐based catalysts for the oxygen reduction reaction in fuel cells. Despite the significant advancement made in activity, their viability as fuel cell catalysts is still questionable due to their low durability. So far, deciphering the degradation mechanisms of this class of catalysts has been hampered by their undefined structure. Herein, we used a molecular model catalyst, iron‐phthalocyanine, featuring Fe−N4 active sites with resemblance to those in the more active Fe−N−C catalysts, and studied their degradation mechanisms. Based on X‐ray photoelectron spectroscopy and the electrochemical measurements, three main demetallation processes were identified: at potentials higher than 0.65 V vs. RHE, where the metal center is Fe3+, an electrochemical oxidation of the ligand ring is occurring, between 0.6 and 0.2 V vs. RHE, Fenton reagents are produced and attack the catalyst and support, and at lower voltages, where peroxide is produced by the catalyst and the carbon support. The combination of the different iron oxidation states together with the oxygen species directs to different degradation mechanisms. The decay rates obtained in the stability measurements establish what is mainly causing the loss of activity. Thereby, this model molecule can aid in understanding the degradation mechanisms of other platinum group metal‐free oxygen reduction reaction catalysts.

Published: March 2023

SummaryCloud computing is currently one of the prime choices in the computing infrastructure landscape. In addition to advantages such as the pay‐per‐use bill model and resource elasticity, there are technical benefits regarding heterogeneity and large‐scale configuration. Alongside the classical need for performance, for example, time, space, and energy, there is an interest in the financial cost that might come from budget constraints. Based on scalability considerations and the pricing model of traditional public clouds, a reasonable optimization strategy output could be the most suitable configuration of virtual machines to run a specific workload. From the perspective of runtime and monetary cost optimizations, we provide the adaptation of a Hadoop applications execution cost model extracted from the literature aiming at Spark applications modeled with the MapReduce paradigm. We evaluate our optimizer model executing an improved version of the Diff Sequences Spark application to perform SARS‐CoV‐2 coronavirus pairwise sequence comparisons using the AWS EC2's virtual machine instances. The experimental results with our model outperformed 80% of the random resource selection scenarios. By only employing spot worker nodes exposed to revocation scenarios rather than on‐demand workers, we obtained an average monetary cost reduction of 35.66% with a slight runtime increase of 3.36%.
Atypical anorexia nervosa diagnosis should exclude those with lifetime anorexia nervosa: Commentary on Walsh, Hagan, and Lockwood (2022)
Authors: Eddy Kamryn T. , Breithaupt Lauren 
Published: March 2023

AbstractAtypical anorexia nervosa (AN) is not well‐defined. Walsh, Hagan, and Lockwood (2022) review the data on atypical AN published in the last decade demonstrating overwhelming clinical similarities between atypical AN and AN. As written, atypical AN includes at least three clinical presentations that may not have the same underlying illness, and in turn, may have different prognoses and treatment needs: (1) higher‐weight AN; (2) prodromal AN; and (3) partial remission from AN. While useful for the first two presentations, we suggest that the atypical AN diagnosis is not appropriate for those in partial remission from AN. Extant data document symptom fluctuation is part of illness course in AN rather than crossover to a distinct disorder. Further, lifetime AN carries the greatest risk for relapse to low‐weight, premature death, and medical morbidities. Finally, emerging data support unique biobehavioral mechanisms in AN suggesting its combination with atypical AN is premature. Therefore, at this time, we recommend that the atypical AN diagnosis be reserved for those without lifetime AN. We encourage research to test and validate operational definitions of atypical AN and partial remission from AN, and further suggest documentation of lifetime AN across the eating disorders given its prognostic value.

Published: March 2023

AbstractActinyl‐actinyl interactions are particularly prevalent for the pentavalent neptunyl cation (Np(V)O2)+where these interactions appear either as aT‐ orD‐shape (diamond‐shape).T‐shaped interactions have been previously identified in high concentration Np(V) solutions containing simple anions (NO3−, ClO4−, Cl−) whereasD‐shaped have only been isolated in the solid‐state in the presence of carboxylate ligands. In this study, Density Functional Theory (DFT) calculations were paired with Raman spectroscopy to evaluate the formation ofD‐shaped interactions in the presence of aliphatic (R=H (formate), CH3(acetate), CH2CH3(propionate)) and aromatic (R=C6H5(benzoate), C6H4OH (4‐hydroxybenzoate), C5H4N (isonicotinate)) carboxylate ligands. DFT studies indicate that the ΔGto form hydratedT‐ andD‐shaped forms are not spontaneous but become so with the addition of the carboxylate ligands. Raman spectra of the Np(V) carboxylate solutions contained vibrational modes associated with theD‐shaped interactions, but spectral changes observed over time indicate a dynamic system. Crystallization experiments from the Np(V) carboxylate systems confirmed the presence ofD‐shaped dimers for the aromatic carboxylates, suggesting that the choice of the anion in solution favors actinyl‐actinyl interactions even at low concentrations (≤20 mM) of Np(V).

Published: March 2023

AbstractThe silver and gold L‐methionine capped nanoparticles (Ag and Au @LM NPs) were analyzed as prospective acetylcholinesterase (AChE) inhibitors to test their potential in the treatment of cognitive impairment in depression and Alzheimer's disease. The stability of NPs, and their ability to inhibit AChE were studied by UV‐Vis and FTIR spectrophotometry. At the same time, TEM and SEM measurements, DLS, and zeta potential measurements were employed in the structural characterization of NPs. Nearly spherical, negatively charged Ag and Au @LM NPs, with 17 nm and 31 nm in diameter, respectively, showed moderate inhibitory potential toward AChE in the given frame of investigated concentrations. For both NPs IC50 is not reached. Furthermore, the adsorption of enzyme molecules on the surface of Ag and Au @LM NPs was demonstrated. Hence, our assumption is that inhibition of AChE is caused by blockage of the enzyme‘s active site due to the steric hindrance of NPs.

Published: March 2023

AbstractA new fluorophore, α‐acrylaldehyde 3‐pyrrolyl BODIPY was synthesized by treating 3‐pyrrolyl BODIPY with a mixture of 3‐(dimethylamino) acrolein and POCl3 under Vilsmeier–Haack reaction conditions. The X‐ray structure revealed that the fluorophore was almost planar, and the appended pyrrole was in the same plane with a small deviation from the mean plane. We investigated the potential use of α‐acrylaldehyde 3‐pyrrolyl BODIPY for sensing thiol containing amino acids such as cysteine/homocysteine (Cys/Hcy). Our studies showed that the α‐acrylaldehyde‐ 3‐pyrrolyl BODIPY was found to be useful for exclusive sensing of Cys/Hcy and to exhibit different optical signaling responses to Cys and Hcy at physiological pH in aq. CH3CN (1 : 1 v/v, PBS) medium. The enhancement in optical properties for Cys and quenching in same properties for Hcy was attributed to different binding modes of Cys/Hcy with α‐acrylaldehyde 3‐pyrrolyl BODIPY.
