Published: July 2022

AbstractThe development of efficient and cost‐effective electrocatalysts toward the oxygen evolution reaction (OER) is highly desirable for clean energy and fuel conversion. Herein, the facile preparation of Ni single atoms embedded hollow S/N‐doped carbon macroporous fibers (Ni SAs@S/N‐CMF) as efficient catalysts for OER through pyrolysis of designed CdS‐NiSx/polyacrylonitrile composite fibers is reported. Specifically, CdS provides the sulfur source for the doping of polyacrylonitrile‐derived carbon matrix and simultaneously creates the hollow macroporous structure, while NiSx is first reduced to nanoparticles and finally evolves into single Ni atoms through the atom migration‐trapping strategy. Benefiting from the abundantly exposed single Ni atoms and hollow macroporous structure, the resultant Ni SAs@S/N‐CMF electrocatalysts deliver outstanding activity and stability for OER. Specifically, it needs an overpotential of 285 mV to achieve the benchmark current density of 10 mA cm−2 with a small Tafel slope of 50.8 mV dec−1.

AbstractThe electrocatalytic water splitting is greatly affected by overpotential, stability, and accessibility of active sites. Designing appropriate active components and tailoring their microstructure are crucial to improve electrocatalytic performance. Herein, using metal organic framework (MOF) as template, novel Ni2P@C composites are prepared as bifunctional catalysts for hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). The best Ni2P@C‐350 sample has a small onset overpotential (η) of 57 mV, and up to 148 and 285 mV to afford 10 and 250 mA cm–2 for HER. It only needs η = 326 mV at 10 mA cm−2 for OER, better than usual RuO2 electrode. Moreover, Ni2P@C‐350||Ni2P@C‐350 cell can work for overall water splitting more efficiently than common Pt/C||RuO2 cell, running stably within 30 h without obvious degradation. The excellent performance is attributed to its porous structure with easily accessible active sites, short ions transfer path, and superior structural stability, which enable a significant improvement on molecule level, e.g., the turnover frequency (TOF) of Ni2P@C‐350 at η = 250 mV is up to 0.84 s−1, while that of pristine Ni2P is only 0.55 s−1. These results highlight the effect of structure engineering, inspiring for electrode design of HER and OER.

Published: July 2022

AbstractIn this work, a chiral functionalized bis‐benzoxanethonyl unit is introduced into three conjugated polymer backbones (S‐/R‐BP, S‐/R‐WP1, and S‐/R‐WP2) as the emitting layers (EMLs) of organic light‐emitting diodes (OLEDs) to construct full‐color circularly polarized electroluminescence (CP‐EL) by solution‐processing. Interestingly, standard white CP‐EL based on the monodispersed S‐/R‐WP2 achieves a high color rendering index of 95 at CIE coordinates of (0.33, 0.34). The CP‐OLED performances show the turn‐on voltage of ≈5.8 V, high maximum luminance of ≈3000 cd m−2, and stable gEL value of 10−3 in the wavelength range of 425–760 nm. This work is the first example to realize standard white CP‐OLEDs by intramolecular chirality transfer mechanism from chiral blue‐color moiety to achiral red‐color dye through polymer chain, which provides a valuable strategy to develop white CP‐EL for potential lighting and full‐color 3D displays.
Acid‐Catalyzed Synthesis of Diverse Indol‐3‐Yl‐Substituted Tetrahydropyridines through Three‐Component Reactions
Authors: Zhu Hongmei , Chen Lei , Bai Rongxian , Gu Yanlong 
Published: July 2022

AbstractTwo classes of indole‐tetrahydropyridine hybrid molecules were synthesized via three‐component reactions of: (i) 1‐amino‐3,3‐diethoxypropane, diethyl acetylenedicarboxylate and indole; and (ii) ethyl 3‐aminocrotonate, acrolein and 2‐methylindoles. These one‐pot reactions provided straightforward ways to access indole‐tetrahydropyridine hybrid molecules with enriched molecular diversity. The reactions were most likely triggered by Michael addition, and the generated adducts were trapped by the indole component, leading to the formation of indol‐3‐ylimine intermediate. The obtained indol‐3‐yl‐substituted tetrahydropyridines could be converted into indole‐pyridine hybrid molecules with the aid of DDQ.magnified image

Published: July 2022

AbstractWater is one of the most important elements for life on earth. Water's rapid phase‐change ability along with its environmental and biological compatibility also makes it a unique structural material for 3D printing of ice structures reproducibly and accurately. This work introduces the freeform 3D ice printing (3D‐ICE) process for high‐speed and reproducible fabrication of ice structures with micro‐scale resolution. Drop‐on‐demand deposition of water onto a −35 °C platform rapidly transforms water into ice. The dimension and geometry of the structures are critically controlled by droplet ejection frequency modulation and stage motions. The freeform approach obviates layer‐by‐layer construction and support structures, even for overhang geometries. Complex and overhang geometries, branched hierarchical structures with smooth transitions, circular cross‐sections, smooth surfaces, and micro‐scale features (as small as 50 µm) are demonstrated. As a sample application, the ice templates are used as sacrificial geometries to produce resin parts with well‐defined internal features. This approach could bring exciting opportunities for microfluidics, biomedical devices, soft electronics, and art.

AbstractWell dispersible and stable single atom catalysts (SACs) with hydrophilic features are highly desirable for selective hydrogenation reactions in hydrophilic solvents towards important chemicals and pharmaceutical intermediates. A general strategy is reported for the fabrication of hydrophilic SACs by cation‐exchange approach. The cation‐exchange between metal ions (M = Ni, Fe, Co, Cu) and Na+ ions introduced in the skeleton of metal oxide (TiO2 or ZrO2) nanoshells plays the key role in forming M1/TiO2 and M1/ZrO2 SACs, which efficiently prevents the aggregation of the exchanged metal ions. The as‐obtained SACs are highly dispersible and stable in hydrophilic solvents including alcohol and water, which greatly facilitates the catalysis reaction in alcohol. The Ni1/TiO2 SACs have been successfully utilized as catalysts for the selective C=C hydrogenation of cinnamaldehyde to produce phenylpropanal with 98% conversion, over 90% selectivity, good recyclability, and a turnover frequency (TOF) of 102 h−1, overwhelming most reported catalysts including noble metal catalysts.

Published: July 2022

AbstractIntegration of complementary logic circuits using 2D layered MoS2 can overcome the fundamental device limitations of silicon‐based Complementary metal–oxide–semiconductor (CMOS) technology. For the high functionality of complementary MoS2 logic circuits, realizing high‐current p‐channel MoS2 field‐effect transistors (p‐FETs) is essential yet quite challenging. Herein, passivation of surface defects of MoS2 by atomic oxygen is proposed theoretically by ab initio simulations in favor of mitigating the Fermi level pinning. Experimentally, an atomic layer passivation (ALP) technique combined with a slow metal‐deposition strategy is developed to reduce contact resistance to p‐channel MoS2 and report a more than tenfold increase in the contact hole conductance. The fabricated p‐channel MoS2 FETs achieve a record high saturation current of 45 µA µm−1 with a 0.7 µm channel length under a VDS of −1 V. With these techniques, an electron–hole pairing in MoS2 similar to the Si counterpart is achieved for complementary circuit applications. An on‐chip integrated MoS2 inverter with Pt electrodes is demonstrated with a high gain of 20 at 3 V supply.

Published: July 2022

AbstractLong‐lived luminescent materials possess wide application prospects in various areas, but their constructions still face a huge challenge, especially the achievement in solution. Manipulating aggregate is an effective method to attain intriguing luminescence, thus it is expected to build long‐lived materials in solution. In this work, a series of new gold(I) complexes were developed by employing unique carbazole and phosphine as the ligands, and these resulting systems exhibited rare long lifetimes of milliseconds in the aggregate state. It was well unveiled that these complexes emitted blue thermally activated delayed fluorescence (TADF) with the lifetimes of several microseconds in dilute solution; while orange‐red phosphorescence with much longer lifetimes of several milliseconds were achieved in the aggregate state. To our knowledge, this is the first implementation of aggregation‐induced conversion from TADF to phosphorescence. Based on their excellent luminescent properties, we successfully applied these complexes in cell imaging and inhibition of cancer cells.
Reinterpreting a “Roman villa” site: First results of nondestructive archaeological research in Dračevica (Donji Radišići, Bosnia and Herzegovina)

Published: July 2022

AbstractThe article presents the results of archaeological prospection of site Dračevica (Donji Radišići, Ljubuški municipality, West Herzegovina Canton, Bosnia and Herzegovina) which was partly excavated in the late 19th century and so far has been interpreted as a Roman villa, possibly with a special function (road station) and a name attested in ancient sources (Bigeste). Through the use of various nondestructive prospecting methods (aerial photogrammetry, fieldwalking survey, magnetic susceptibility, magnetometry, earth resistance), precise location with RTK GNSS and integration of the data in GIS, the site was restudied and reinterpreted. It was established that the structures are not isolated, as was assumed in the earlier research but rather were a part of a much larger Roman settlement. The research proves that the internal spatial division of the site is more complicated than previously thought, consisting of several building complexes located along a road, as well as land division systems. Such settlement pattern suggests similar, average‐sized land plots and farms. The importance of the research lies also in the methodological approach and the outcome of the geophysical research. Our research was the first application of nondestructive methods of archaeological prospection on Roman sites in the karst landscapes of West Herzegovina, proving the usefulness of the applied methodology in these specific and difficult conditions. We have found dependencies in between the geological background (thin layer of low resistive, colluvial soil on shallow limestone bedrock and the occurrence of highly magnetic terra rossa, formed on weathered limestone) and the geophysical responses registered by various instruments, that is, moderate to good magnetic and electric contrasts between the features and their surroundings, with relatively strong anomalies from geological features. The most important was finding relationships between particular magnetic and electrical anomalies and the presence of very shallow bedrock or faint archaeological remains (e.g. limestone walls). Our methodology, as well as some of our interpretations, will be helpful as a reference for further surveys in the region.

AbstractBackgroundIn Japan, the government designates hospitals specialized in cancer care, requiring them to perform 400 surgeries annually without requiring surgical volume per cancer site. This study aimed to estimate the site‐specific minimum surgical volume per year based on its associations with 5‐year survival probability.MethodsThe data of 64,402 patients who had undergone surgery for six types of cancers (including esophageal, stomach, colorectal, pancreatic, lung, and breast cancers) at designated cancer care hospitals in Osaka between 2007 and 2011 were analyzed. The hospitals were categorized by the average annual surgical volume per cancer type (e.g., 0–4, 5–9, 10–14…). We estimated the adjusted 5‐year survival probability per surgical volume category using multivariable Cox proportional hazard regression. Furthermore, we identified inflection points for the trend of adjusted survival probability per increase of five surgical volumes using the joinpoint regression model and considered them as the suggested minimum surgical volume.ResultsThe estimated minimum surgical volumes were 35–39, 20–25, 25–29, 10–14, 10–14, and 25–29 for esophageal, stomach, colorectal, pancreatic, lung, and breast cancers, respectively. The percentage change in the adjusted 5‐year survival probability per increase of five surgical volumes before and after the suggested surgical volume were +2.23 and +0.39 for the esophagus, +9.68 and +0.34 for the stomach, +8.11 and +0.05 for the colorectum, +3.82 and +0.87 for the pancreas, +9.46 and +0.23 for the lung, and +1.27 and +0.03 for the breast.ConclusionsThe suggested surgical volume based on the association with survival probability varies with cancer sites, some of which are close to the existing surgical volume standards used in Japan. These evidence‐based minimum surgical volumes may help improve the quality of cancer surgeries.
Disentangling audio content and emotion with adaptive instance normalization for expressive facial animation synthesis

Published: July 2022

Abstract3D facial animation synthesis from audio has been a focus in recent years. However, most existing literature works are designed to map audio and visual content, providing limited knowledge regarding the relationship between emotion in audio and expressive facial animation. This work generates audio‐matching facial animations with the specified emotion label. In such a task, we argue that separating the content from audio is indispensable—the proposed model must learn to generate facial content from audio content while expressions from the specified emotion. We achieve it by an adaptive instance normalization module that isolates the content in the audio and combines the emotion embedding from the specified label. The joint content‐emotion embedding is then used to generate 3D facial vertices and texture maps. We compare our method with state‐of‐the‐art baselines, including the facial segmentation‐based and voice conversion‐based disentanglement approaches. We also conduct a user study to evaluate the performance of emotion conditioning. The results indicate that our proposed method outperforms the baselines in animation quality and expression categorization accuracy.

Published: July 2022

AbstractIn essentially one‐pot, using Ir‐ and Pd‐catalysis, tris(arene)‐functionalized cationic [4]helicenes are synthesized with full regioselectivity and enantiospecificity starting from a trivial precursor (17 examples). This poly‐addition of aryl groups improves key optical properties, that is, fluorescence quantum yields and lifetimes. Electronic circular dichroism and circularly polarized luminescence signatures are observed up to the far‐red domain, in particular with additional arenes prone to aggregation.

AbstractHN0037 is a helicase‐primase inhibitor developed to treat herpes simplex virus (HSV) infection. This study evaluated the safety, tolerability, and pharmacokinetics of HN0037, following oral administration in healthy volunteers. This double‐blind, placebo‐controlled, phase 1 study comprised two parts. In part 1, a single escalating dose of 10, 30, 60, 120, 200, 300, and 400 mg was assessed, and the food effect was evaluated in the 200‐mg cohort. In part 2, a multiple dose evaluation involving 30 and 100 mg once a day was conducted for 14 days. Following single oral doses, the systemic exposure of HN0037 increased in a proportional manner over the lower dose range (10–120 mg) and in a subproportional manner over the higher dose range (200–400 mg). Following multiple oral doses, significant drug accumulation of systemic exposure was found at steady state, and the half‐life ranged 50.4‐61.0 h. The food effect study results indicated that a high‐fat meal had a marginal impact on HN0037's pharmacokinetics. No differences were observed in the incidence of adverse events between HN0037 and placebo groups in either study. These results demonstrate that HN0037 is safe and well‐tolerated, supporting further clinical development.
A new method for task scheduling in fog‐based medical healthcare systems using a hybrid nature‐inspired algorithm
Authors: Wang Bingxian , Wu Peng , Arefzaeh Maryam 
Published: July 2022

SummaryThe goal of the healthcare system is to offer a dependable and well‐organized solution for improving human's wellbeing. Examining a patient's history can assist clinicians in considering the patient's wants when building a healthcare system and providing service, resulting in increased patient satisfaction. Thus, healthcare is becoming a more competitive sector. Massive data volume, latency, response time, and security susceptibility are all difficulties resulting from this substantial increase in healthcare systems. As a famous distributed structure, fog computing might thus aid in the resolution of such problems. Processing parts are situated among end devices and cloud components in a fog computing infrastructure and run programs. This design is well suited to real‐time and low‐latency applications, like healthcare systems. Because task scheduling is an NP‐hard optimization issue in fog‐based medical healthcare systems, this work proposes a hybrid genetic algorithm and particle swarm optimization (GA‐PSO) strategy. A powerful single‐objective optimization technique is the GA‐PSO. Individuals in a novel generation are formed in GA‐PSO through mutation and crossover operations in GA‐PSO, which uses a redefined local optimization swarm. Hence, it may avoid local minimums and perform well in global searches. The study's goal in fog‐based medical healthcare systems is to lower the makespan and overall response time. The suggested technique is simulated in MATLAB and compared to the GA and PSO methods. The empirical findings confirmed the improved makespan, making the approach appropriate for medical and real‐time systems applications.

Published: July 2022

AbstractTechnical artifacts such as clogging that occur during the data acquisition process of flow cytometry data can cause spurious events and fluorescence intensity shifting that impact the quality of the data and its analysis results. These events should be identified and potentially removed before being passed to the next stage of analysis. flowCut, an R package, automatically detects anomaly events in flow cytometry experiments and flags files for potential review. Its results are on par with manual analysis and it outperforms existing automated approaches.

AbstractBackgroundThe potential loss of CD19 during targeted treatment of B cell precursor acute lymphoblastic leukemia (BCP‐ALL) can hamper flow cytometric minimal residual disease (MRD) monitoring. In the current study, we present expression data for antigens that are candidates for CD19 substitution: surface CD22, CD24, CD10, and intracellular (i) CD79a.MethodsBone marrow samples from 519 consecutive children (below 18 y.o.) with primary BCP‐ALL were studied with a focus on expression of CD19, CD10, CD22, CD24, and iCD79a. As these antigens are planned to be used as substitutions for CD19 for primary B cell gating, only total expression on the leukemic population (≥95% cells) was considered appropriate.ResultsIt was found that each of these antigens is totally expressed in nearly 90% of patients. For each single marker, a subgroup of patients without complete positivity presented with BCP‐ALL harboring diverse cytogenetic and molecular genetic aberrations. Based on expression data, we have developed algorithm of simultaneous application of these antigens for initial B‐lineage compartment gating, that is applicable for nearly all patients after CD19 targeting.ConclusionWe conclude that the addition of CD22, CD24, and iCD79a to the conventional antibody panel and their application together with CD10 allow for the identification of B‐lineage compartment including residual tumor blasts, for MFC‐MRD searching in virtually all patients with BCP‐ALL after CD19‐directed treatment.
