AbstractTheir outstanding electrical and optical properties make semiconducting single‐walled carbon nanotubes (SWCNTs) highly suitable for charge transport and emissive layers in near‐infrared optoelectronic devices. However, the luminescence spectra of SWCNT thin films on commonly used glass and Si/SiO2 substrates are often compromised by broadening of the main excitonic emission and unwanted low‐energy sidebands. Surface passivation with a commercially available, low dielectric constant, cross‐linked bis‐benzocyclobutene‐based polymer (BCB) enhances the emission properties of SWCNTs to the same level as hexagonal boron nitride (h‐BN) flakes do. The presence of BCB suppresses sideband emission, especially from the Y1 band, which is attributed to defects introduced by the interaction of the nanotube lattice with oxygen‐containing terminal groups of the substrate surface. The facile and reproducible deposition of homogeneous BCB films over large areas combined with their resistance against common solvents and chemicals employed during photolithography make them compatible with standard semiconductor device fabrication. Utilizing this approach, light‐emitting (6,5) SWCNT network field‐effect transistors are fabricated on BCB‐treated glass substrates with excellent electrical characteristics and near‐intrinsic electroluminescence. Hence, passivation with BCB is proposed as a standard treatment for substrates used for spectroscopic investigations of and optoelectronic devices with SWCNTs and other low‐dimensional emitters.

AbstractAcetaminophen (APAP) overdose is a leading cause of drug‐induced liver injury and acute liver failure, while the detection, prognosis prediction, and therapy for APAP‐induced liver injury (AILI) remain improved. Here, it is determined that the temporal pattern of circulating cell‐free DNA (cfDNA) is strongly associated with damage and inflammation parameters in AILI. CfDNA is comparable to alanine aminotransferase (ALT) in predicting mortality and outperformed ALT when combined with ALT in AILI. The depletion of cfDNA or neutrophils alleviates liver damage, while the addition of cfDNA or adoptive transfer of neutrophils exacerbates the damage. The combination of DNase I and N‐acetylcysteine attenuates AILI significantly. This study establishes that cfDNA is a mechanistic biomarker to predict mortality in AILI mice. The combination of scavenging cfDNA and reducing oxidative damage provides a promising treatment for AILI.

AbstractUncontrolled hemorrhage is still the most common cause of potentially preventable death after trauma in prehospital settings. However, there rarely are hemostatic materials that can achieve safely and efficiently rapid hemostasis simultaneously. Here, new carbonized cellulose‐based aerogel hemostatic material is developed for the management of noncompressible torso hemorrhage, the most intractable issue of uncontrolled hemorrhage. The carbonized cellulose aerogel is derived from theAgaricus bisporusafter a series of processing, including cutting, carbonization, purification, and freeze‐drying. In vitro, the carbonized cellulose aerogels with porous structure show improved hydrophilicity, good blood absorption, and coagulation ability, rapid shape recoverable ability under wet conditions. And in vivo, the carbonized aerogels show effective hemostatic ability in both small and big animal serious hemorrhage models. The amount of blood loss and the hemostatic time of carbonized aerogels are all better than the positive control group. Moreover, the mechanism studies reveal that the good hemostatic ability of the carbonized cellulose aerogel is associated with high hemoglobin binding efficiency, red blood cell absorption, and platelets absorption and activation. Together, the carbonized aerogel developed in this study could be promising for the management of uncontrolled hemorrhage.

AbstractThe Zn anode in aqueous zinc‐ion batteries (AZIBs) is severely impeded by uncontrolled dendrite growth and promiscuous water‐induced side reactions, resulting in low Coulombic efficiency (CE) and poor lifetime. Herein, a versatile Zn‐based laponite (Zn–LT) interface is constructed for uniform and rapid Zn deposition for long‐life AZIBs. The combined experimental results and theoretical simulations reveal that the abundant negatively charged channels in the Zn–LT layer permit cation penetration but shield anions to uniformly modulate Zn deposition. Moreover, Zn–LT not only acts as a desolvation layer to promote Zn deposition kinetics, but also effectively inhibit harmful Zn anode corrosion. Therefore, the functional Zn–LT interface enables the anode to deliver an average CE as high as 99.8% at 1 mA cm−2 and a long lifespan of >830 h at 10 mA cm−2 and 5 mA h cm−2. Moreover, the assembled MnO2||Zn–LT@Zn full battery exhibits prominent rate performance (123 mA h g−1 at 2 A g−1) and long‐term cycling stability (80.4% capacity retention at 1 A g−1 after 700 cycles). Furthermore, the fabrication of this Zn‐LT@Zn anode can be extended to rolling method, reflecting the industrial manufacturing potential.

AbstractThe intercalation of protons represents a notable component for energy storage in aqueous zinc‐ion batteries. However, the mechanism of proton transport in metal oxide cathodes, especially related to how the cation distribution modulates the proton‐conducting lanes, remains far from consensus due to the lack of suitable model materials. Here, taking spinel ZnMn2O4cathode as a prototype, it is disclosed that a deficiency of one half of lattice Zn ions can triple its specific capacity at high rates, which is predominantly contributed by proton storage. This promotion can be rationalized by the emergence of facile concerted proton transport in the Zn‐deficient sample, contrasting with the stoichiometric one, where proton intercalation undergoes a slow consecutive process. Furthermore, the restricted Zn motion in spinel phase causes high structural stability during cycling, preventing the recombination of external Zn ions with Zn vacant sites that readily accommodate protons. This work highlights the key role of controlled off‐stoichiometry in optimizing proton transport and storage for aqueous batteries.

Published: April 2023

AbstractNonaqueous carbonate electrolytes are commonly used in commercial lithium‐ion battery (LIB). However, the sluggish Li+diffusivity and high interfacial charge transfer resistance at low temperature (LT) limit their wide adoption among geographical areas with high latitudes and altitudes. Herein, a rational design of new electrolytes is demonstrated, which can significantly improve the low temperature performance below −20 °C. This electrolyte is achieved by tailoring the chemical structure, i.e., altering the fluorination position and the degree of fluorination, of ethyl acetate solvent. It is found that fluorination adjacent to the carbonyl group or high degree of fluorination leads to a stronger electron‐withdrawing effect, resulting in low atomic charge on the carbonyl oxygen solvating sites, and thus low binding energies with Li+ions at LT. The optimal electrolyte 2,2,2‐trifluoroethyl acetate (EA‐f) shows significantly improved cycle life and C‐rate of a NMC622/graphite cell when cycled at −20 °C and −40 °C, respectively. In addition to superior LT performance, the electrolyte is nonflammable and tolerant for high voltage charging all owing to its fluorine content. This work provides guidance in designing next‐generation electrolytes to address the critical challenge at subzero temperatures.

Published: April 2023

AbstractThe practical deployment of lithium metal anodes in rechargeable batteries has been significantly restricted by poor electrochemical performance, which largely stemms from their high susceptibility to corrosion. Inan effort to complete the real picture of Li corrosion pathways, in this contribution, a dynamic galvanic corrosion mechanism under realistic working conditions is described, through which an extended solid electrolyte interphase (SEI) is progressively generated on the successively exposed copper substrate during the dynamic Li removal process. As determined by the titration gas chromatography method, the dynamic galvanic corrosion reaction is unveiled to induce an unfavorable extra Li loss and hence a reduced cell reversibility, especially at sluggish Li stripping rates. Systematic investigations reveal that three critical factors, including total step length of Li stripping, dynamic corrosion current (icorrosion) degradation speed, and SEI chemistry, are responsible form odulating the extent of dynamic galvanic corrosion in practical batteries. This work provides an important complement to current knowledge regarding the corrosion processes of working Li metal anodes, affording fresh insights into the design strategies toward high‐reversibility Li cycling.

AbstractAntimony chalcogenides (Sb2(SxSe1−x)3, 0 < x < 1) have recently gained popularity due to their excellent photoelectric properties. As a newcomer to thin‐film solar cells, the quality of the as‐prepared absorb layer remains the most difficult challenge, owing to its distinct crystal structure. Here, a solvent‐assisted hydrothermal deposition (SHD) technique is developed for direct deposition of high‐quality Sb2(S,Se)3 films; it is realized that the addition of ethanol can regulate the reaction kinetics by regulating the concentration of the Sb source during the deposition procedure. Impressively, under such conditions, the deposition rate of the target absorb layer slows dramatically, resulting in more suitable features, such as large grain size, smooth surface, and proper bandgap, which are beneficial for constructing high performance solar devices. More importantly, using this newly developed SHD strategy, the defect (SbS1) density of the prepared films decreases by more than one order of magnitude, which is believed to benefit carrier transport. As a result, Sb2(S,Se)3 solar cells based on the SHD strategy significantly improve fill factor and short‐circuit current density, yielding a high efficiency of 10.75%. This research offers fresh insights into how to make Sb2(S,Se)3 films and solar cells of higher quality.

AbstractThe electrochemical CO2reduction reaction (CO2RR) is an attractive method to produce renewable fuel and chemical feedstock using clean energy sources. Formate production represents one of the most economical target products from CO2RR but is primarily produced using post‐transition metal catalysts that require comparatively high overpotentials. Here a composition of bimetallic Cu–Pd is formulated on 2D Ti3C2Tx(MXene) nanosheets that are lyophilized into a highly porous 3D aerogel, resulting in formate production much more efficient than post‐transition metals. Using a membrane electrode assembly (MEA), formate selectivities >90% are achieved with a current density of 150 mA cm−2resulting in the highest ever reported overall energy efficiency of 47% (cell potentials of −2.8 V), over 5 h of operation. A comparable Cu‐Pd aerogel achieves near‐unity CO production without the MXene templating. This simple strategy represents an important step toward the experimental demonstration of 3D‐MXenes‐based electrocatalysts for CO2RR application and opens a new platform for the fabrication of macroscale aerogel MXene‐based electrocatalysts.

Published: April 2023

BackgroundNeurofibromatosis type I is rarely associated with vascular abnormalities. Here, we report a case of rapid airway stenosis caused by a ruptured occipital artery that was treated with surgical airway management.Case PresentationA 40‐year‐old woman, with no medical history, presented with a chief complaint of a sudden neck pain on the left side. She had a prominent mass in the outer left side of the neck. After arrival at the emergency room, the patient complained of severe dyspnea and experienced a rapid drop in oxygen saturation. Supplemental ventilation was ineffective, and tracheal intubation was attempted; however, laryngeal expansion could not be observed because of the enlarged cervical mass. Therefore, to manage the surgical airway, a cricothyrotomy was first carried out, which resulted in an immediate increase in oxygen saturation. Two percutaneous embolizations and one surgical procedure were carried out, and the patient was discharged without any complications.ConclusionFor a sudden onset cervical mass, airway management should be undertaken, keeping in mind the possibility of worsening rapid airway narrowing due to bleeding.

ObjectiveAcute dizziness/vertigo is usually due to benign inner‐ear causes but is occasionally due to dangerous neurologic ones, particularly stroke. Because symptoms and signs overlap, misdiagnosis is frequent and overuse of neuroimaging is common. We assessed the accuracy of bedside findings to differentiate peripheral vestibular from central neurologic causes.MethodsWe performed a systematic search (MEDLINE and Embase) to identify studies reporting on diagnostic accuracy of physical examination in adults with acute, prolonged dizziness/vertigo (“acute vestibular syndrome” [AVS]). Diagnostic test properties were calculated for findings. Results were stratified by examiner type and stroke location.ResultsWe identified 6,089 citations and included 14 articles representing 10 study cohorts (n = 800). The Head Impulse, Nystagmus, Test of Skew (HINTS) eye movement battery had high sensitivity 95.3% (95% confidence interval [CI] = 92.5–98.1) and specificity 92.6% (95% CI = 88.6–96.5). Sensitivity was similar by examiner type (subspecialists 94.3% [95% CI = 88.2–100.0] vs non‐subspecialists 95.0% [95% CI = 91.2–98.9],p = 0.55), but specificity was higher among subspecialists (97.6% [95% CI = 94.9–100.0] vs 89.1% [95% CI = 83.0–95.2],p = 0.007). HINTS sensitivity was lower in anterior cerebellar artery (AICA) than posterior inferior cerebellar artery (PICA) strokes (84.0% [95% CI = 65.3–93.6] vs 97.7% [95% CI = 93.3–99.2],p = 0.014) but was “rescued” by the addition of bedside hearing tests (HINTS+). Severe (grade 3) gait/truncal instability had high specificity 99.2% (95% CI = 97.8–100.0) but low sensitivity 35.8% (95% CI = 5.2–66.5). Early magnetic resonance imaging (MRI)‐diffusion‐weighted imaging (DWI; within 24–48 hours) was falsely negative in 15% of strokes (sensitivity 85.1% [95% CI = 79.2–91.0]).InterpretationIn AVS, HINTS examination by appropriately trained clinicians can differentiate peripheral from central causes and has higher diagnostic accuracy for stroke than MRI‐DWI in the first 24–48 hours. These techniques should be disseminated to all clinicians evaluating dizziness/vertigo. ANN NEUROL 2023;94:295–308

AbstractThe synthesis of wafer‐scale single‐crystal graphene sheets has become essential to realize future electronic device applications. To synthesize large‐area boundary‐free graphene, it is effective to use chemical vapor deposition (CVD) on copper (Cu) surfaces that possess a thin oxide layer. In this study, we constructed machine learning (ML) modeling to design experimental CVD conditions for the formation of large‐area graphene. The constructed ML model predicted the graphene domain size from the experimental CVD growth conditions and the spectral information of the Cu surface. Furthermore, we demonstrated the formation of large‐area graphene domain on the Cu surface using the CVD conditions determined by the constructed ML model, which provided faster graphene growth compared to previously reported strategies.

Published: April 2023

AbstractQiufengN is a silkworm strain. During the feeding process of QiufengN, a mutant of black pupal cuticle QiufengNBP was found. Some silkworm pupae of the mutant were unable to easily molt during pupation, and some silkworm eggs produced by developed normally but larvae were unable to break out of the eggshells. These phenomena had not been observed in other black pupa mutants. Genetic analysis showed that the melanization trait of QiufengNBP is controlled by a recessive gene located on the autosome and follows Mendelian inheritance. Results of positional cloning and qRT‐PCR showed that the occurrence of black pupae was caused by the mutation of the ebony gene on chromosome 26. 2‐DE analysis of the pupal cuticle of QiufengN and QiufengNBP found that the 30K protein, the main storage protein for the growth and development of silkworms and an important energy substance for embryonic development, has changed significantly. In addition, the expression level of Bombyx mori hatching enzyme (BmHEL), which can soften the eggshell during the hatching process of silkworm, was significantly higher in the eggs of black pupae before and after hatching than in normal eggs. The mutation of ebony makes hatching difficult for silkworms, and increases in BmHEL is needed to soften the eggshell. This study showed that ebony may have important effects on the formation of silkworm pigment and egg hatching, and its formation mechanism is complex and deserves further study.
Leveraging baseline covariates to analyze small cluster‐randomized trials with a rare binary outcome

Published: April 2023

AbstractCluster‐randomized trials (CRTs) involve randomizing entire groups of participants—called clusters—to treatment arms but are often comprised of a limited or fixed number of available clusters. While covariate adjustment can account for chance imbalances between treatment arms and increase statistical efficiency in individually randomized trials, analytical methods for individual‐level covariate adjustment in small CRTs have received little attention to date. In this paper, we systematically investigate, through extensive simulations, the operating characteristics of propensity score weighting and multivariable regression as two individual‐level covariate adjustment strategies for estimating the participant‐average causal effect in small CRTs with a rare binary outcome and identify scenarios where each adjustment strategy has a relative efficiency advantage over the other to make practical recommendations. We also examine the finite‐sample performance of the bias‐corrected sandwich variance estimators associated with propensity score weighting and multivariable regression for quantifying the uncertainty in estimating the participant‐average treatment effect. To illustrate the methods for individual‐level covariate adjustment, we reanalyze a recent CRT testing a sedation protocol in 31 pediatric intensive care units.
World society and the convergence of consumer values: Buying patterns of eco‐certification in the UAE

Published: April 2023

AbstractEco‐certifications offer consumers the opportunity to vote with their money for more sustainable methods of production. While consumer‐facing eco‐labels are mostly recognized and consumed in western countries little is known about their performance in expat societies. This study applies world society theory to a sample of Arab, Western, and South Asian United Arab Emirates (UAE) residents to test whether globalization causes assimilation of familiarity, attitudes, and buying frequencies for major eco‐labels. The results show that respondents with Western ethnicities are more familiar with eco‐certifications. However, Arab, and South‐Asian citizens report similar or higher levels of importance for the purported benefits of eco‐certifications. Among respondents familiar with eco‐certification, we found no differences in buying frequency by ethnic group. Findings related to ethnicity support world society theory because social, environmental, and quality ideals converge among different ethnic groups in the UAE.
