AbstractRegeneration of cathode materials from spent lithium‐ion batteries (LIBs), as an efficient short‐range recycling strategy, is gradually becoming a research hotspot. However, due to the unavoidable influence of impurities in the recycling process, the regenerated material suffers from severe performance degradation during the recycling process. Surface coating is an effective routine to improve cycling stability. Here, regenerated Li(Ni0.8Co0.1Mn0.1)O2 cathode material is successfully wet‐coated by an appropriate amount of MoO3. The study finds the material loading 2.0 wt% MoO3 exhibits even better properties. After 100 cycles, the capacity retention efficiency is significantly improved from 70 % to 86.5 % in the range of 2.8∼4.3 V. It is confirmed that the MoO3 coating effectively stabilized the cathode/electrolyte interface, thus reducing the occurrence of side reactions and improving the electrochemical stability of the battery. In addition, the MoO3 had great electrical conductivity, keeping the lithium diffusion even at a stable level upon cycling. To sum up, our work provides a simple and available modification strategy for nickel‐rich cathode materials recovered from spent LIBs.

AbstractAqueous Zn‐ion batteries (AZIBs) have attracted lots of attention due to good eco‐friendly, safety and high energy density. However, the dendritic growth and side reactions on Zn anodes have affected the safety and stability of AZIBs. In this paper, an artificial interface protective layer on the Zn anode has been fabricated by a convenient and straightforward replacement reaction of Bi(CF3SO3)3 with Zn anode in dimethoxyethane (DME) solution at room temperature. The Ar+ etching X‐ray photoelectron spectrometer (XPS) proves that the protective layer is composed of metal Bi, ZnS and ZnSO3, suggesting the success of replacement reaction. This artificial protective layer is propitious to control nucleation sites of Zn2+ and favorable Maxwell‐Wagner polarization, resulting in uniform Zn stripping/plating. In addition, the scanning electron microscope (SEM), Tafel plots and X‐ray diffraction (XRD) demonstrate that the interface layer can effectively suppress side reactions and dendrite growth. Therefore, the symmetric cells with modified Zn anode exhibit superior cycling stability at diverse current densities with a fixed capacity of 1 mAh cm−2 and higher coulombic efficiency (CE) than half‐cells with pristine Zn anode. Simultaneously, modified Zn/NH4V4O10 full‐cells present higher specific capacity, superior cycling stability and rate capability. This simple method provides a new way to modify the Zn anodes for the development of industrialization of aqueous rechargeable ZIBs.

Ionic Liquids Mediated One‐Pot Synthesis of Second Generation 5‐Ethoxymethylfurfural (5‐EMF); A Potent Biofuel Candidate
Authors: Naz Sadia , Uroos Maliha 
Published: May 2022

Abstract5‐Ethoxymethylfurfural (5‐EMF) is a promising fuel alternative and biofuel additive due to its high energy potential. Principal method for its synthesis is etherification of hydroxyl group of 5‐hydroxymethylfurfural (5‐HMF), produced by the dehydration of fructose. Currently existing methods for the synthesis of 5‐EMF are not industrially feasible due to the issues associated with their starting materials; either they are highly expensive (such as 5‐HMF), or compete with food (sugars such as fructose and glucose). Herein, we are reporting a one‐pot protocol for the synthesis of 5‐EMF using non‐food indigenous agricultural waste material, thus completely eliminating the both issues. Cost is also very much reduced due to the utilization of cheap pyridinium based ionic liquids. Energy, time and solvents use is also reduced, as reaction is happening in a single pot. The process is optimized first for fructose (73 % 5‐EMF yield) and glucose (16 % 5‐EMF), and was then extended for real biopolymeric cellulose (16 % 5‐EMF) and wheat husk biomass (15 % 5‐EMF). Product was characterized via HPLC and 1HNMR spectroscopy.
Structural, Electrochemical and Catalytic Elucidation of Cyclooctadiene Ru(II)‐Nitrile Complexes of the Type [RuCl2(cod)(NCR)2]
Authors: Malan Frederick P. 
Published: May 2022

AbstractThe facile synthesis of a range of eleven cyclooctadiene Ru(II) complexes of the type [RuCl2(cod)(NCR)2] featuring different nitrile ligands using two synthetic routes is reported. The solid‐state characterization (SCXRD) of twelve complexes is also described. Complex instability in solution led to spontaneous dimerization to yield a dimeric complex. Using these complexes, varied catalytic activity was observed in six different transformation reactions, of which the transfer hydrogenation of ketones was the highest (yields of 99 % after 30 minutes, TOF=156 h−1). The electrochemical (CV), DFT, and catalytic properties of the complexes evaluated showed that while the majority of the characteristics of the complexes are comparable, three complexes stood out with the lowest catalytic activity (16 % and lower), the highest (most positive) formal redox potentials for RuII/RuIII (E0′ of up to +1.4 V), as well as exhibiting some of the smallest energy gaps (as small as 1.21 eV) in the series.
A blessing and a curse: How chief executive officer cognitive complexity influences firm performance under varying industry conditions
Authors: Malhotra Shavin , Harrison Joseph S. 
Published: May 2022

AbstractResearch SummaryHow CEO cognitive complexity influences firm outcomes raises an intriguing theoretical tension. While more cognitively complex CEOs can potentially bolster firm performance through their more elaborate and multifaceted information processing, those tendencies can also hurt performance because they require more time and energy, delaying decision making. We posit and show a nuanced effect of CEO cognitive complexity on firm performance, contingent on industry conditions. CEO cognitive complexity benefits performance under more complex, stable, and munificent industry conditions, but hurts performance under simpler, more dynamic, and more constrained conditions. Post‐hoc analyses further show that these effects are similar when considering firm‐level factors reflecting munificent and dynamic internal conditions. Our study highlights the boundary conditions under which CEO cognitive complexity may be beneficial or detrimental for firms.Managerial SummaryCEOs have different cognitive styles that can impact how they approach decision making. Whereas some exhibit greater cognitive complexity, that is, by engaging in broader and deeper information search and considering more differentiated and nuanced perspectives and alternatives, others engage in simpler and less comprehensive information processing when making decisions. While it seems intuitive to assume that CEOs' cognitive complexity should be beneficial for firms, collecting and processing a large amount of complex information can also complicate and delay decision‐making. Our results show that S&P 1500 CEOs who are more cognitively complex improve firm performance when their firms operate in more complex, stable, and resource‐rich environments but hurt firm performance when their firms operate in simpler, more dynamic, and resource‐constrained environments.

Published: May 2022

AbstractMicro/nanorobots represent a new generation of micromachines that can accomplish various tasks, such as loading and transporting specific targets or pharmaceuticals for a given application. Biohybrid robots consisting of biological cells (bacteria, sperm, and microalgae) combined with inorganic particles to control or propel their movement are of particular interest. The skeleton of these biohybrid robots can be used to load biomolecules. In this work, the authors create biohybrid robots based on tomato plants by coculturing ferromagnetic nanoparticles (Fe3O4) with tomato callus cells. The tomato‐based biohybrid robots (Tomato‐Biobots) containing Fe3O4 nanoparticles are driven by a transversely rotating magnetic field. In addition, biohybrid robots are used to load vitamin C, to generate clones of tomato cells. It is shown that the presence of Fe3O4 does not affect the growth of tomato callus. This study opens a wide range of possibilities for the use of biohybrid robots@Fe3O4 to deliver conventional agrochemicals, including fertilizers, pesticides, and herbicides, and allows for a gradual and sustained release of nutrients and agrochemicals, leading to precise dosing that reduces the amount of agrochemicals used. This conceptually new type of micromachine with application to plants and agronomy shall find broad use in this field.

SummaryDue to creep and shrinkage of concrete, the long‐term structural deformation is one of the hottest topics in the study of super high‐rise structures. For the frame–eccentrical core tube structure, its long‐term deformation includes both vertical deformation and obvious horizontal deformation, which will have an inevitable influence on the structural verticality. The horizontal deformation and its formation mechanism in frame–eccentrical core tube structure are studied in this paper. Based on the finite element software ETABS, a refined finite element model combining with the time‐dependent material model of concrete is established base on a subsistent structure. According to the actual construction conditions, construction analysis is conducted, and the construction deformation and the long‐term deformation after completion are subsequently studied. Based on the results of construction analysis, the effects of elastic modulus, creep, and shrinkage on structural horizontal deformation are analyzed; furthermore, the horizontal deformation characteristics of different structural members in different periods are compared. The results show that the horizontal deformation is related to the vertical deformation of the component, and creep and shrinkage exert opposite effects on the structural horizontal deformation. Besides, the creep and shrinkage are the dominant factors of the horizontal deformation in the later stage. These results are supported by real deformation data obtained from real‐time deformation monitoring during construction, which proves the effectiveness of the method adopted in this paper.

AbstractMitogen‐activated protein kinase (MAPK or MPK) cascades consist of three protein kinase components, MAPK kinase kinases (MAPKKKs), MAPK kinases (MKKs and MPKs), which are indispensable for various plant physiological processes. The functions of MAPK families have been extensively studied in maize (Zea mays L.) and other plant species, but little is known about MAPK families in the elite Chinese maize line Huangzaosi (hzs). In this study, we observed that overall performance of Huangzaosi was substantially better than that of B73 under drought conditions at the seedling and V16 stages with a favorable root/canopy ratio. In silico analyses identified 72, 10, and 24 MAPKKKs, MKKs, and MPKs, respectively, in Huangzaosi. Examinations of phylogenetic relationships among Arabidopsis thaliana (L.) Heynh., rice (Oryza sativa L.), and maize (lines B73 and hzs), gene structures, conserved protein motifs, and chromosomal locations revealed their evolutionary relationships. The basal gene expression levels and tissue specificities of all three MAPK families in hzs reflected the diversity in the MAPK functions related to growth and development. The quantitative real‐time polymerase chain reaction (qPCR) assay indicated that certain MAPK genes with high basal expression levels in the primary and crown roots responded differentially to drought between B73 and hzs, suggesting that these genes may contribute to their distinct drought tolerance at different developmental stages. The important information regarding the evolution and expression of hzs MAPK family members generated in this study provides a new avenue for the better understanding on the regulatory mechanism of MAPK cascade in the core inbred line hzs, which may be useful to guide the development of new maize cultivars with desirable traits (e.g., drought resistance).

AbstractBackgroundHistorically sinonasal malignancies were always addressed via open craniofacial surgery for an oncologic resection. Increasingly esthesioneuroblastomas are excised using an exclusively endoscopic approach, however, the rarity of this disease limits the availability of long‐term and large scale outcomes data.ObjectiveThe primary objective is to evaluate the treatment modalities used and the overall survival of patients with esthesioneuroblastoma managed with exclusively endoscopic surgery.MethodsIn accordance with PRISMA guidelines, PubMed was queried to identify studies describing outcomes associated with endoscopic management of esthesioneuroblastomas.ResultsForty‐four out of 2462 articles met inclusion criteria, totaling 399 patients with esthesioneuroblastoma treated with an exclusively endoscopic approach. Seventy‐two patients (18.0%) received adjuvant chemotherapy and 331 patients (83.0%) received postoperative radiation therapy. The average age was 50.6 years old (range 6–83). Of the 399 patients, 57 (16.6%) were Kadish stage A, 121 (35.2%) were Kadish stage B, 145 (42.2%) were Kadish stage C, and 21 (6.1%) were Kadish stage D. Pooled analysis demonstrated that 66.0% of patients had Hyams histologic Grade Ⅰ or Ⅱ, while 34.0% of patients had Grade Ⅲ or Ⅳ disease. Negative surgical margins were achieved in 86.9% of patients, and recurrence was identified in 10.3% of patients. Of those with 5‐year follow‐up, reported overall survival was 91.1%.ConclusionExclusively endoscopic surgery for esthesioneuroblastoma is performed for a wide range of disease stages and grades, and the majority of these patients are also treated with adjuvant chemotherapy or radiation therapy. Reported overall recurrence rate is 10.3% and 5‐year survival is 91.1%.

AbstractObjectiveProficiency in endoscopic endonasal skull base surgery requires both substantial baseline training and progressive lifelong learning. Endoscopic simulation models continue to evolve in an effort to optimize trainee education and preoperative preparation and improve surgical outcomes. The current scoping review systematically reviews all available literature and synthesizes the current paradigms of simulation models for endoscopic skull base surgery training and skill enhancement.MethodsIn accordance with Preferred Reporting Items for Systemic Review and Meta‐Analyses guidelines, we systematically searched PubMed, Embase, CINAHL, and Cochrane databases. Studies were categorized according to the type of simulation models investigated.ResultsWe identified 238 unique references, with 55 studies ultimately meeting inclusion criteria. Of these, 19 studies described cadaveric dissection models, 17 discussed three‐dimensional (3D) printed models, 14 examined virtual surgical planning and augmented reality‐based models, and five 5 articles described task trainers.ConclusionsThere are a wide variety of simulation models for endoscopic skull base surgery, including high‐fidelity cadaveric, virtual reality, and 3D‐printed models. These models are an asset for trainee development and preoperative surgical preparation.

AbstractObjectivesTo demonstrate three‐hundred and sixty degrees of maxillary sinus (MS) surgical approaches using cadaveric dissections, highlighting the step‐by‐step anatomy of each procedure.MethodsTwo latex‐injected cadaveric specimens were utilized to perform surgical dissections to demonstrate different approaches to the MS. The procedures were documented with macroscopic images and endoscopic pictures.ResultsDissections were performed to approach the MS medially (endoscopic maxillary antrostomy and ethmoidectomy), anteriorly (Caldwell–Luc), superiorly (transconjunctival/transorbital approach), inferiorly (transpalatal approach), and posterolaterally (preauricular hemicoronal approach).ConclusionA number of approaches have been described to address pathology in the MS. Surgeons should be familiar with indications, limitations, and surgical anatomy from different perspectives to approach the MS. This paper illustrates anatomic approaches to the MS with detailed step‐by‐step cadaveric dissections and case examples.

Published: May 2022

AbstractObjectiveEndoscopic repair of large anterior skull base (ASB) defects has excellent results when using multilayered repairs with a nasoseptal flap. However, in extensive intranasal tumors, a nasoseptal flap may not always be available. One alternative option is a flexible single‐layer ASB repair. Initial studies indicate low cerebrospinal fluid leak rates with a single‐layer repair. However, the level of frontal lobe support, particularly the propensity for a significant inferior displacement of the frontal lobe, is not known. The goal of this study is to determine the frontal lobe position after single‐layer acellular dermal allograft repair in large ASB defects.Study DesignRetrospective cohort study.SettingTertiary care medical center.Subjects and MethodsThis cohort study compares the frontal lobe position in adults who underwent endoscopic endonasal ASB tumor resection and single‐layer cadaveric dermal matrix repair (ASB cohort) with control subjects without intracranial abnormalities (control cohort). The ASB cohort includes subjects with an ASB defect of ≥5 cm anterior/posterior and ≥1.5 cm wide and who had imaging at least 2 months after surgery. The frontal lobe position is measured on sagittal CT/MRI using a reference line from the base of the sella to the nasion. A value of zero indicates that the inferior‐most aspect of the frontal lobe is at the level of the nasion−sellar line. A positive value indicates that the frontal lobe is inferior to the nasion−sellar line. The ASB cohort frontal lobe position is compared with the control cohort using the Mann−Whitney U test. A priori we set an absolute difference of 5 mm as a clinically significant difference.ResultsThe ASB cohort includes 47 subjects who are 57% male with an average age of 60 years (range: 31−89 years). The most common ASB pathology is esthesioneuroblastoma (n = 21) and 81% of the ASB cohort had postoperative radiation. The control cohort includes 20 subjects who are 60% male, with a mean age of 45 years (range: 19−74 years). The majority of controls underwent imaging for head trauma (n = 13). The ASB mean frontal lobe position is −0.2 mm superior to the nasion−sellar line (range: −9.2 to 10.4 mm), while the control's mean frontal lobe position is 1.1 mm inferior to the nasion−sellar line. This difference is not statistically significant (P = 0.13) and does not reach our a priori definition of clinical significance. The frontal lobe position of ASB subjects who had radiation is closer to the nasion−sellar line as compared with those who did not undergo radiation.ConclusionsSingle‐layer acellular dermal graft repair maintains frontal lobe support and position in large ASB defects.
The Draf III procedure: A review of indications and techniques
Authors: Noller Michael , Fischer Jakob L. , Gudis David A. , Riley Charles A. 
Published: May 2022

AbstractThe Draf Ⅲ procedure involves the creation of a common frontal sinus cavity. The most common indication for the Draf Ⅲ procedure is chronic rhinosinusitis of the frontal sinuses despite the failure of more conservative interventions such as bilateral Draf Ⅱa procedures. Primary Draf Ⅲ may be indicated in patients with a high risk of failures such as those with severe polyposis and those with a frontal sinus opening less than 4 mm on computed tomography imaging. Other indications for the Draf Ⅲ include access for tumor removal and repair of traumatic fractures of the frontal sinus. The “inside‐out” Draf Ⅲ procedure is the standard approach when the frontal recess anterior–posterior diameter is wide enough for instrument access, usually larger than 4–5 mm. The “outside‐in” Draf Ⅲ procedure can be done when the frontal recess is too narrow to safely accommodate instruments. Regular follow‐up with debridement should be done to prevent neo‐ostium stenosis.
