Anisotropic Contraction in a Magnetically Hard but Mechanically Ultra‐Soft Foam for Precise Drug Delivery
Authors: Zong Zisheng , Zhang Shuo , Wu Zhigang 
Published: January 2023

AbstractHard magnetic soft materials (HMSMS) have been recently intensively explored in soft robots, owing to its native advantages such as untethered, rapid and reversible actuation, as well as large shape changes. However, in the existing studies, HMSMS is majorly applied by a magnetic field to produce bending, folding, and even twisting, that is, shape morphing, to realize multimodal locomotion. Meanwhile, such as contraction deformation, which may be employed in precise drug delivery, has been neglected in a long term. Here, an anisotropic contraction in a porous structure, hard magnetic foam (HMF), which is mechanically ultra‐soft (with a shear modulus of 4.5 kPa) but magnetically hard (with a residual magnetic flux density of 12 mT), is reported. The investigation of HMF structures indicates that anisotropic contraction is dominated by the magnetodeformational effect and the magnetic body‐force against support constraint. By adjusting the magnetic fields directions, the relationship between these two factors can be regulated to achieve a maximum contraction of 43% (synergy) or negligible deformation (antagonism). Finally, HMF is utilized to realize precision drug delivery since it has the advantages of no leakage during moving, precisely adjustable drug release rate (from 0.008 to 0.62 mL min−1), and no residues after leaving.

Published: January 2023

AbstractProtonic ceramic electrochemical cells (PCECs) have been intensively studied as the technology that can be employed for power generation, energy storage, and sustainable chemical synthesis. Recently, there have been substantial advances in electrolyte and electrode materials for improving the performance of protonic ceramic fuel cells and protonic ceramic electrolyzers. However, the electrocatalytic materials development for synthesizing chemicals in PCECs has gained less attention, and there is a lack of systematic and fundamental understanding of the PCEC reactor design, reaction mechanisms, and electrode materials. This review comprehensively summarizes and critically evaluates the most up‐to‐date progress in employing PCECs to synthesize a wide range of chemicals, including ammonia, carbon monoxide, methane, light olefins, and aromatics. Factors that impact the conversion, selectivity, product yield, and energy efficiencies are discussed to provide new insights into designing electrochemical cells, developing electrode materials, and achieving economically viable chemical synthesis. The primary challenges associated with producing chemicals in PCECs are highlighted. Approaches to tackle these challenges are then offered, with a particular focus on deliberately designing electrode materials, aiming to achieve practically valuable product yield and energy efficiency. Finally, perspectives on the future development of PCECs for synthesizing sustainable chemicals are provided.

Published: January 2023

AbstractStructural colors materials are profoundly explored owing to their fantastic optical properties and widespread applications. Development of structural color materials bearing flexible morphologies and versatile functionalities is highly anticipated. Here, a droplet‐confined, magnetic‐induced self‐assembly strategy for generating rotary structural color spindles (SCSPs) by fast solvent extraction is proposed. The as‐prepared SCSPs exhibit an orderly close‐packed lattice structure, thus appearing brilliant structural colors that serve as encoding tags for multiplexed bioassays. Besides, benefitting from the abundant specific surface area, biomarkers can be labeled on the SCSPs with high efficiency for specific detection of analytes in clinical samples. Moreover, the directional magnetic moment arrangement enables contactless magnetic manipulation of the SCSPs, and the resultant rotary motions of the SCSPs generates turbulence in the detection solution, thus significantly improving the detection efficiency and shortening the detection time. Based on these merits, a portable point‐of‐care‐testing strip integrating the rotary SCSPs is further constructed and the capability and advantages of this platform for multiplexed detection of tumor‐related exosomes in clinical samples are demonstrated. This study offers a new way for the control of bottom‐up self‐assembly and extends the configuration and application values of colloidal crystal structural colors materials.

AbstractHighly sensitive and reliable hydrogen detection is prerequisite for the large‐scale implementation of green energy hydrogen. It remains a tough challenge to get a highly selective H2 sensor to low concentration H2 gas with low working temperature. In this work, high performance flexible hydrogen sensor using ultrathin SnO2 film decorated by Pd nanoparticles (NPs) on polyimide (PI) was developed based on versatile atomic layer deposition (ALD) and cluster beam deposition (CBD). The influence of Pd NPs loading amount and operating temperature on the performance of hydrogen sensors was studied. The sensors obtain an extremely high response over 20000 to 30 ppm H2 at the relatively low operating temperature of 75–125 °C. The Pd NPs@SnO2/PI sensor achieves a wide detection range of 0.1‐5000 ppm with the limit of detection (LOD) of 100 ppb at 125 °C. A low LOD of 250 ppb can still be achieved at room temperature. The sensors also exhibit outstanding sensing selectivity for hydrogen over interfering gases and excellent mechanical resistance after 2000 bending cycles. The mechanism for improved sensing performance of ALD ultrathin film with CBD‐derived noble metal NPs decoration may be a feasible strategy for the construction of highly sensitive, selective, and flexible hydrogen sensors.

AbstractThe O3‐type Ni‐rich NaNixCoyMn1−x−yO2 (x ≥ 0.6) oxides are regarded as one of the most promising cathodes for high‐capacity Na‐ion batteries (NIBs), however, they still suffer from severe structural/morphological degradation induced by complicated phase transitions, as well as sluggish de‐/sodiation kinetics. For this, a multi‐level structural/compositional modification strategy, including “core–shell” design, bulk heteroatom doping, and surface coating, is purposefully explored to construct an advanced NaNi0.6Co0.2Mn0.2O2 cathode (denoted as T‐CSN6@A). The Ni‐rich core guarantees the high capacity, and the Mn‐rich surface region coupled with bulk Ti doping and surface Al2O3 coating reinforces the structural stability. This well‐designed architecture not only effectively inhibits the bulk and sur‐/interface structural fractures caused by repeated lattice volume variations upon cycling, but also dramatically boosts the de‐/sodiated kinetics, thus resulting in high chemomechanical stability and improved electronic/ionic transport for efficient sodium storage. When utilized as a competitive cathode, the T‐CSN6@A‐based quasi‐solid‐state NIBs are endowed with remarkable wide‐temperature‐tolerance Na‐storage behaviors within practicable working temperatures from −20 to 50 °C, along with an attractive material‐level energy density of ≈255 Wh Kg−1 at 25 °C. The feasible modification here provides a new avenue for advanced O3‐type Ni‐rich cathodes toward large‐scale industrialization of next‐generation NIBs.

AbstractSeasonal changes in the human cardiovascular system are known to play an important role in the onset of many diseases. Confounding variables include behavioral and environmental factors; failing to address such variables makes measuring the true temporal impact of these diseases difficult. On the other hand, numerous clinical studies imply that only specific groups of people are more seasonal sensitive and that their maladaptation might contribute to various illnesses. As a result, it is critical to evaluate the etiological and seasonal sensitive patterns of cardiovascular diseases (CVD), which impact the majority of the human population. The hypothesis for this study formulated that cardiovascular and associated illnesses had substantial connections with seasonal and etiological variations. Thus in the present study, 4519 systematic screen‐eligible studies were analyzed using data mining to uncover 852 disease association relationships between cardiovascular and associated disorders. A disease ontology‐based semantic similarity network (DSN) analysis was performed to narrow down the identified CVDs. Further, topological analysis was used to predict the seven CVDs, including myocardial infarction (MI), in three clusters. Following that, Mann–Kendall and Cox–Stuart analyses were used to investigate the seasonal sensitivity and temporal relationship of these seven CVDs. Finally, temporal relationships were confirmed using LOESS and TBATS, as well as seasonal breakdown utilizing autocorrelation and fast Fourier transform results. The study provides indirect evidence of a severe etiological association among the three cardiovascular diseases, including MI, atrial fibrillation, and atherosclerosis, which are winter season sensitive in most of the world population. Hypertension has two seasonal falls and peaks due to its seasonal nature, that is, summer and winter hypertension. While, heart failure was also identified, with minor temporal trends. Hence, all five diseases could be classified as seasonal cardiovascular comorbid diseases (SCCD). Furthermore, these diseases could be studied for potential common risk factors such as biochemical, genetic, and physiological factors.
Progress of Catalytic Mitsunobu Reaction in the Two Decades
Authors: Zhang Kui , Chen Yang , Song Liangliang , Cai Lingchao 
Published: January 2023

AbstractAn important goal of modern synthetic chemistry is the development of highly efficient and selective processes that minimize the formation of waste, which are desirable for economy and environmental requirements. The classic Mitsunobu reaction has been adopted widely for converting alcohols into numerous functional groups and undergoes an inversion of stereochemistry in SN2 reaction when secondary alcohols are employed. However, the reaction is far from ideal in terms of its environmental impact, requiring stoichiometric amounts of a phosphine (III) and an azodicarboxylate, and producing stoichiometric amounts of hydrazine and phosphine oxide wastes. The first attempt to access the catalytic Mitsunobu reaction dates back to 2006 by Toy's group and since then, several groups including Taniguchi, O'Brien, Aldrich, Denton and their co‐workers have opted for this promising alternative. Generally, the substantial progress has been made in the development of catalytic Mitsunobu reaction involving redox‐driven and redox‐neutral processes. The elegant redox‐driven catalytic system applies either external reductants or oxidants to recycle azo or phosphine reagents, while the preeminent redox‐neutral catalytic system is undergoing the activation step to proceed. This review summarizes the related developments in the recent two decades and presents the future research direction.
Evaluating barriers and strategies to sustainable supply chain risk management in the context of an emerging economy

Published: January 2023

AbstractWith increasing awareness about society and the environment, industries are urged to develop and implement sustainable supply chain (SSC) processes. However, the risk of non‐compliance against these SSC processes to manage overall business risks, namely, avoiding reputational damage and managing financial losses, is increasingly receiving senior management attention. Given these shortcomings, the objective of this research is twofold, namely, (i) to identify and evaluate barriers adopting sustainable supply chain risk management (SSCRM) processes and (ii) to prioritize SSCRM strategies to overcome these barriers in an emerging economy, namely, Bangladesh. To achieve the objectives, this study develops a framework by integrating the technique for order of preference by similarity to ideal solution (TOPSIS) and VIsekriterijumska optimizacija i KOmpromisno Resenje (VIKOR). The results show that the “information‐related barriers” are most prevalent among the categories of barriers, and “lack of coordination and collaboration” has been identified as the most significant barrier. Evaluating the strategies, “top management commitment” is the best strategy. These findings can help managers develop strategies to overcome the most significant barriers to adopting SSCRM. The proposed framework, which integrates quantitative and qualitative approaches, can be used by decision‐makers to make accurate, prompt, and systematic decisions compliant with SSCRM business processes.

Published: January 2023

AbstractPhotocatalytic hydrogen production via solar energy is considered one of the most strategic ways to produce renewable energy. However, expensive Pt is normally used as the cocatalyst during photocatalysis, which prevents commercialization. Therefore, extensive research has been performed to seek abundant and low‐cost alternative catalysts. In this work, MoS2 quantum dots (QDs) synthesized by a hydrothermal method are incorporated with graphitic carbon nitride to form a heterostructure for photocatalytic hydrogen evolution. MoS2 QDs/g‐C3N4 heterostructure containing 5% and 10% MoS2 QDs exhibited a high hydrogen production of 140 and 152 µmol h−1g−1, respectively, demonstrating the potential of MoS2 as an effective economic cocatalyst. Detailed investigations indicate that incorporating MoS2 QDs with carbon nitride to form heterostructure reduces the bandgap, suppresses the recombination, and enhances electron kinetic energy resulting from the anti‐Stoke effect, thus leading to better performance for hydrogen evolution.
Citral Hydrogenation over Dilute Alloy Catalysts

Published: January 2023

AbstractDilute alloy CuPt and NiPt catalysts are studied in the hydrogenation of citral, a model α,β‐unsaturated aldehyde. In situ and ex situ characterization is used to demonstrate that the Pt species within these nanoparticles are well dispersed and approach a single atom alloy structure. The distribution of Pt varies between the two host metal systems; under a hydrogen environment, the nanoparticle surface and near‐surface region of the NiPt nanoparticles is Pt rich, while the Pt is more uniformly distributed throughout the CuPt nanoparticles. When used for citral hydrogenation reactions, a rate enhancement is observed upon the addition of Pt to the Cu or Ni host catalysts, however this enhancement is determined to be due to the presence of additional metal and not a synergistic effect of the two metals. The Pt structure does, nonetheless, influence the observed selectivity trends. NiPt/SiO2 catalysts have high selectivity to the unsaturated aldehyde citronellal while the CuPt/SiO2 catalysts have increased selectivity to unsaturated alcohol products. This increased selectivity is attributed to a combination of hydrogen dissociation over Pt sites and a decrease in size of Cu ensembles due to the presence of Pt, which favors binding and hydrogenation of C=O rather than C=C bonds.

Published: January 2023

AbstractFacile sulfation of TiO2 semiconductor photocatalyst was achieved by a simple grinding and calcination method using elemental sulfur from desulfurization of petroleum. The successful sulfation of the prepared visible‐light‐active photocatalyst was also proved by infrared and X‐ray photoelectron spectroscopic measurements. Photocatalytic tests revealed that the most efficient member of the series has higher photocatalytic activity than TiO2 in the photodegradation of formic acid under both UV and visible‐light activation. Moreover, the improved electrokinetic and water dispersibility behaviors of the sulfur‐modified photocatalyst allowed the preparation of polyacrylate‐based photoreactive thin films with increased photocatalytic activity, strong antimicrobial properties, and improved mechanical behavior.

Published: January 2023

AbstractThis work demonstrates the in‐line monitoring of a flow photochemical reaction using 1D and ultrafast 2D NMR methods at high magnetic field. The reaction mixture exiting the flow reactor is flown through the NMR spectrometer and directly analyzed. In the case of simple substrates, suitable information can be obtained through 1D 1H spectra, but for molecules of higher complexity the use of 2D experiments is key to address signal overlaps and assignment issues. Here we show the usefulness of ultrafast 2D COSY experiments acquired in 70 s or less, for the in‐line monitoring of photochemical reactions, and the possibility to obtain reliable quantitative information. This is a powerful framework to, for example, efficiently screen reaction conditions.

AbstractControlling aspects of the μ2‐X− bridging anion in the metal–organic framework Ga‐MIL‐53 [GaX(bdc)] (X−=(OH)− or F−, bdc=1, 4‐benzenedicarboxylate) is shown to direct the temperature at which thermally induced breathing transitions of this framework occur. In situ single crystal X‐ray diffraction studies reveal that substituting 20 % of (OH)− in [Ga(OH)(bdc)] (1) for F− to produce [Ga(OH)0.8F0.2(bdc)] (2) stabilises the large pore (lp) form relative to the narrow pore (np) form, causing a well‐defined decrease in the onset of the lp to np transition at higher temperatures, and the adsorption/desorption of nitrogen at lower temperatures through np to lp to intermediate (int) pore transitions. These in situ diffraction studies have also yielded a more plausible crystal structure of the int‐[GaX(bdc)] ⋅ H2O phases and shown that increasing the heating rate to a flash heating regime can enable the int‐[GaX(bdc)] ⋅ H2O to lp‐[GaX(bdc)] transition to occur at a lower temperature than np‐[GaX(bdc)] via an unreported pathway.
Substrate‐Controlled Product Divergence in Iron(III)‐Catalyzed Reactions of Propargylic Alcohols: Easy Access to Spiro‐indenyl 1,4‐Benzoxazines and 2‐(2,2‐Diarylvinyl)quinoxalines
Authors: De Sukanya , Chowdhury Chinmay 
Published: January 2023

AbstractWe report herein unprecedented cascade reactions of O‐propargyl‐N‐tosyl‐amino phenols with 10 mol% FeCl3 in DCE at room temperature for 0.67–3 h to form spiro‐indenyl 1,4‐benzoxazines with 38–89 % yield. Replacing the substrates’ oxygen atom by a N‐tosylimine group followed by treatment with the same catalyst and solvent at 80 °C produced 2‐(2,2‐diarylvinyl)quinoxalines in 12–20 h with up to 62 % yield. Mechanistic understanding provided an insight into the transformations. The use of simple substrates and an environmentally benign low‐cost catalyst, broad substrate scope and tolerance of diverse functional groups makes the methodology inherently attractive.
Benign peripheral nerve tumors: Analysis of 89 FNA cases emphasizing diagnostic accuracy and their morphologic spectrum
Authors: Wakely Paul E. 
Published: January 2023

AbstractIntroductionBenign peripheral nerve tumors (BPNTs) are a heterogenous group of soft tissue tumors that include a variety of nerve sheath tumors, granular cell tumor (GCT), and ganglioneuroma. Only a few large studies exist on cytopathology and diagnostic accuracy using fine‐needle aspiration (FNA) biopsy for this set of neoplasms.Materials and methodsBoth surgical and cytopathology files were searched for cases of BPNT. FNA biopsy was performed using standard techniques.ResultsEighty‐nine cases from 88 patients (male:female = 1:1; age range: 16–85 years, mean age, 51 years) met inclusion criteria. FNA sites included extremities (58, 65%), head/neck (14, 16%), deep (9, 10%), and trunk (8, 10%). Aspirates were from primary neoplasms in all but one instance. There were 65 schwannomas, seven neurofibromas, seven perineuriomas, seven GCTs, and three ganglioneuromas/neuromas. Aspirates of schwannoma, GCT, neurofibroma (NF), and perineurioma (PN) were correctly diagnosed in 86%, 100%, 29%, and 0% of cases, respectively. Five tumors (6%) were interpreted as either a specific sarcoma or suspicious for sarcoma. Remaining aspirates were classified as spindle cell neoplasm, salivary gland neoplasm, and nondiagnostic. Cytologic features for schwannoma, NF, PN, and ganglioneuroma showed spindle cell–dominant smears arranged mainly in syncytial clusters. GCT aspirates contained a population of epithelioid cells harboring coarsely granular cytoplasm and bare nuclei. Immunohistochemical (IHC) staining in 55 (62%) cases showed S‐100 expression in 95%.ConclusionFNA biopsy coupled with IHC is reliable in correctly classifying schwannoma and GCT, but less so for NF. Perineurioma can be mistaken for sarcoma.
