AbstractFunctionalized fullerene nanostructures are a distinct class of materials that exhibit the combined properties of both fullerene and nanostructures including excellent optoelectronic features, modified band edges, high electron affinity, fast charge transfer capabilities, and tunable structural and textural properties. These fascinating properties allow for their utilization in many applications such as polymer solar cells, photovoltaics, photocatalysis, photodynamic therapy, electrocatalysis, environmental remediation, and drug and gene delivery. Numerous synthesis methods and anchoring groups are employed for functionalized fullerenes with nanostructures by using convergent bottom‐up and top‐down strategies. The supramolecular self‐assembly and functionalization of fullerenes through robust chemistry approaches such as surface oxidation, grafting, polymer coating, doping of metals/nonmetal heteroatoms, noncovalent modification with 2D materials and nanoparticle attachment result in achieving fine control over its surface and bulk properties, including increased solubility, wettability, electron transport, acid–base properties, adsorption, electronic conductivity, and light absorption. This review analyzes the salient developments in the fabrication of nanostructured fullerenes and their functionalized derivatives for many applications including adsorption, catalysis, sensors, energy storage, solar cells, drug delivery, magnetic and superconducting devices. The contents of this review will allow the readers to cherish exciting possibilities and opportunities in field of functionalized nanofullerenes.

AbstractThe utilization of low‐grade and abundant thermal sources based on thermoelectric (TE) materials is crucial for the development of a sustainable society. However, high‐performance thermoelectric materials with biodegradable, mass‐productive, and low‐cost features are rarely reported. Here, from the perspective of sustainable development, natural polymer (bacterial cellulose, BC), and “green” solvent (ionic liquids, ILs) are combined to achieve a transparent, flexible, and robust ionogel (BCIGs) by using a facile and versatile modified co‐solvent evaporation method. The proposed BCIGs with 95 wt% 1‐ethyl‐3‐methylimidazolium dicyanamide ([EMIm][DCA]) can have high tensile strength (3.05 MPa), skin‐like mechanical stretchability (40.99%), and obvious adhesivity. The BCIGs are thermally stable up to 250 °C. They also exhibit a high ionic conductivity (2.88 × 10−2 S cm−1), high ionic thermovoltage (18.04 mV K−1), and low thermal conductivity (0.21 W m−1 K−1), resulting in the great ionic figure of merit (ZTi) of 1.33 at room temperature. Through the model of mesoscopic confined ion transportation under a thermal gradient, it is attributed the great thermoelectric properties to the synergistic effect between ion–cellulose interaction and ion–ion interaction. Moreover, a flexible ionic thermoelectric capacitor (ITEC) device is also demonstrated, showing the potential of the BCIGs in wearable energy supply.

Published: October 2021

AbstractDisplay devices show great application prospects in various fields. Among them, the flexible display which can quickly produce customizable patterns has attracted the attention of researchers. In this study, two types of electroluminescent devices, which introduce liquid metal printed patterns as the electrodes for electrical input, are proposed, theoretically analyzed, and experimentally characterized. One type is to stack the liquid metal electrode, the emissive layer and the transparent electrode in a sandwich configuration. The other is to construct two patterned liquid metal electrodes on one side of the emissive layer and then emit light from the edge of the liquid metal patterns. Compared with the traditional materials, the liquid metal can be quickly patterned so that the obtained liquid metal electroluminescent devices can display customized and erasable luminous patterns. This new display device is easy to access in virtue of various liquid metal printed methods. For practical illustrations, a wristband for monitoring human body temperature and a programmable 8 × 8 pixels flexible screen with double layer liquid metal printed circuits are further designed and demonstrated. This study opens the door to quickly fabricate personalized displays in low quantities based on liquid metal and shows significant potential in flexible electronics.

Published: October 2021

AbstractA simple method for the synthesis of new bio‐based silane coupling agents (SCAs) with a terpene aromatic core by the functionalization of cheap, natural eugenol and its sulfur derivatives using the hydrosilylation of the C=C bonds with HSi(OEt)3, followed by nucleophilic substitution reactions of OH/SH groups is presented. The obtained alkoxysilanes possess different polymer‐reactive functionalities (alkenyl, epoxide, thiirane, thiocarbamoyl, thioester, thioether moieties). This new group of biogenic SCAs was fully characterized using 1H, 13C, 29Si NMR, FT‐IR, GC‐MS, and HRMS or elemental analysis. Examples of their application as additives to tire rubbers and their influence on several factors are also discussed.magnified image

AbstractOptical‐field driven electron tunneling in nanojunctions has made demonstrable progress toward the development of ultrafast charge transport devices at subfemtosecond time scales, and have evidenced great potential as a springboard technology for the next generation of on‐chip “lightwave electronics.” Here, the empirical findings on photocurrent the high nonlinearity in metal–insulator–metal (MIM) nanojunctions driven by ultrafast optical pulses in the strong optical‐field regime are reported. In the present MIM device, a 14th power‐law scaling is identified, never achieved before in any known solid‐state device. This work lays important technological foundations for the development of a new generation of ultracompact and ultrafast electronics devices that operate with suboptical‐cycle response times.

Published: October 2021

AbstractTo realize the continuous development of information and communication equipment, it is also important to develop devices with new operating principles that overcome the functional and performance limitations of conventional electronics devices, such as transistors made of semiconductor materials. One group of devices that hold this promise is nanoionics devices that operate by using local ion transport and electrochemical reaction in solids. A number of nanoionics devices that control nanoelectrochemical phenomena through the use of ionic nanoarchitectonics have been created. Here the use of ionic nanoarchitectonics to locally control ion transport and electrochemical reactions through the use of ion conductors or mixed conductors as device materials is described. Further, the structures of nanoionics devices created by using the nanoarchitectonics, as well as their various electrical, magnetic and optical functionalities are introduced. It is expected that such nanoionics devices will complement conventional electronics devices, and make possible the further development of information and communication technologies.

Published: October 2021

AbstractA key factor in improving semi‐transparent organic photovoltaics (ST‐OPVs) performance is achieving high light utilization efficiency (LUE). However, device performance can also be limited by the lack of understanding of light transmission and reflection within the device architecture, and the transmission of the top electrode in particular. Here, highly efficient ST‐OPVs are reported via the rational design of silver nanowire (Ag NW) top electrodes via 3D optical simulation. Due to its careful consideration for the ST‐OPV of the effect of the Ag NW networking structure, estimated average visible transmission (AVT) and ideal short‐circuit current density values from 3D optical simulation closely match those from actual measurements. Optimized ST‐OPVs with Ag NW porosity of 20% and active layer thickness of 150 nm exhibit LUE of 4.15% with a power conversion efficiency of 9.7% and AVT of 42.82%. This work achieves a record‐high LUE in ST‐OPVs reported to date and the first report introducing a 3D optical simulation study.

Published: October 2021

AbstractTo achieve high efficiency perovskite solar cells (PSCs) based on α‐phase formamidinium lead iodide (FAPbI3), addition of methylammonium chloride (MACl) in the precursor solution is commonly used, mainly because of phase stability and improvement of grain size and crystallinity. However, the instability of MA in the perovskite limits the device long‐term stability. In this report, n‐propylammonium chloride (PACl) is proposed as an alternative to MACl for more stable and efficient FAPbI3‐based PSCs. Perovskite grain size is increased after addition of PACl. Unlike the MA cation, the propylammonium cation passivates the grain boundary rather than being incorporated into the perovskite lattice due to larger ionic size, which minimizes the change in bandgap. Carrier lifetime is significantly increased by more than five times from 405 to 2110 ns with the PACl additive with negligible trap‐mediated recombination, while only four times longer carrier lifetime is observed by MACl additive. As a result, a power conversion efficiency over 22.2% is achieved by 20 mol% PACl additive, which is one of the best efficiencies among the MA‐free and Br‐free PSCs. In addition, stability against moisture is much better for PACl than for MACl due to an in situ formed barrier at the bulk perovskite.

AbstractGain of 1q22 at diagnosis portends poorer outcomes in multiple myeloma (MM), but the prognostic significance of acquired 1q22 gain is unknown. We identified 63 MM patients seen at Mayo Clinic from 1/2004 to 12/2019 without 1q22 gain at diagnosis who acquired it during follow up and compared them to 63 control patients who did not acquire 1q22 gain with similar follow up. We also compared outcomes in the acquired 1q22 gain group with outcomes in 126 patients with 1q22 gain present at diagnosis. The incidence of acquired 1q22 gain was 6.1% (median follow‐up 6.8 years); median time to acquisition was 5.0 years (range: 0.7–11.5 years). Abnormalities on baseline fluorescence in situ hybridization (FISH) included trisomies (54%) and monosomy 13 (39%); 16 (25%) had high‐risk (HR) translocations or del(17p). Median progression‐free survival with front line therapy was 29.5 months in patients with acquired 1q22 gain, versus 31.4 months in control patients (p = .34) and 31.2 months in patients with de novo 1q22 gain (p = .04). Median overall survival (OS) from diagnosis was 10.9 years in patients with acquired 1q22 gain, versus 13.0 years in control patients (p = .03) and 6.3 years in patients with de novo 1q22 gain (p = .01). Presence of HR FISH at baseline increased risk of 1q22 gain acquisition. We demonstrate that acquisition of 1q22 gain is a significant molecular event in MM, associated with reduced OS. Among HR patients for whom this clonal evolution is determined, a risk‐adapted approach and/or clinical trial should be considered.
Overview of age‐related changes in psychomotor and cognitive functions in a prosimian primate, the gray mouse lemur (Microcebus murinus): Recent advances in risk factors and antiaging interventions

Published: October 2021

AbstractAging is not homogeneous in humans and the determinants leading to differences between subjects are not fully understood. Impaired glucose homeostasis is a major risk factor for cognitive decline in middle‐aged humans, pointing at the existence of early markers of unhealthy aging. The gray mouse lemur (Microcebus murinus), a small lemuriform Malagasy primate, shows relatively slow aging with decreased psychomotor capacities at middle‐age (around 5‐year old). In some cases (∼10%), it spontaneously leads to pathological aging. In this case, some age‐related deficits, such as severe cognitive decline, brain atrophy, amyloidosis, and glucoregulatory imbalance are congruent with what is observed in humans. In the present review, we inventory the changes occurring in psychomotor and cognitive functions during healthy and pathological aging in mouse lemur. It includes a summary of the cerebral, metabolic, and cellular alterations that occur during aging and their relation to cognitive decline. As nutrition is one of the major nonpharmacological antiaging strategies with major potential effects on cognitive performances, we also discuss its role in brain functions and cognitive decline in this species. We show that the overall approach of aging studies in the gray mouse lemur offers promising ways of investigation for understanding, prevention, and treatments of pathological aging in humans.

Published: October 2021

AbstractSaccharomyces cerevisiae is an attractive chassis for the production of medium‐chain fatty acids, but the toxic effect of these compounds often prevents further improvements in titer, yield, and productivity. To address this issue, Lem3 and Sfk1 were identified from adaptive laboratory evolution mutant strains as membrane asymmetry regulators. Co‐overexpression of Lem3 and Sfk1 [Lem3(M)‐Sfk1(H) strain] through promoter engineering remodeled the membrane phospholipid distribution, leading to an increased accumulation of phosphatidylethanolamine in the inner leaflet of the plasma membrane. As a result, membrane potential and integrity were increased by 131.5% and 29.2%, respectively; meanwhile, the final OD600 in the presence of hexanoic acid, octanoic acid, and decanoic acid was improved by 79.6%, 73.4%, and 57.7%, respectively. In summary, this study shows that membrane asymmetry engineering offers an efficient strategy to enhance medium‐chain fatty acids tolerance in S. cerevisiae, thus generating a robust industrial strain for producing high‐value biofuels.

Published: October 2021

AbstractBackgroundCervical cancer is the second most common cancer and the leading cause of cancer‐related death in Ethiopian women. About 77.6% of women died of 6294 new cases reported in 2019. Early screening for cervical cancer has substantially reduced morbidity and mortality attributed to it. In Ethiopia, most of the women visit the health facilities at the late stage of the disease in which the offered intervention is not promising. Therefore, we aimed to assess the level of cervical cancer screening uptake and its determinant among women of Ambo town, Ethiopia.MethodsCommunity‐based cross‐sectional study was conducted among 422 women aged 20–65 years. An interviewer‐administered questionnaire was used to collect the data. Data were analyzed using SPSS version 25. Estimates were presented using an odds ratio (OR) with 95% CI. Statistical significance was declared at a p value of <0.05.ResultsIn the present study, 392 women were participated giving a response rate of 93%. Only 8.7% (34) of the study participants were received cervical cancer screening in their lifetime. Being in the age group of 30–39 years (AOR = 3.2, 95% CI: 1.22, 8.36), having cervical cancer‐related discussions with a healthcare provider (AOR = 3.5; 95% CI: 1.17, 10.7), and knowing the availability of cervical cancer screening service (AOR = 2.8; 95% CI: 1.03, 7.87) were significantly associated with uptake of cervical cancer screening.ConclusionIn this study, cervical cancer screening uptake is very low. Our study identifies clues for determinants of cervical cancer screening uptake. Thus, further studies using a better study design might be helpful to explore determinants of low utilization of CC screening services and suggest an appropriate intervention that increases CC screening uptake in the study area.

Authors: Brauer Jan , Quraishi Elisabeth , Kammer Lisa Marie , Opatz Till 
Published: October 2021

AbstractA simple visible light photochemical, nickel‐catalyzed synthesis of ketones from carboxylic acid‐derived precursors is presented. Hantzsch ester (HE) functions as a cheap, green and strong photoreductant to facilitate radical generation and also engages in the Ni‐catalytic cycle to restore the reactive species. With this dual role, HE allows for the coupling of a large variety of radicals (1°,2°, benzylic, α‐oxy & α‐amino) with aroyl and alkanoyl moieties, a new feature in reactions of this type. With both precursors deriving from abundant carboxylic acids, this protocol is a welcome addition to the organic chemistry toolbox. The reaction proceeds under mild conditions without the need for toxic metal reagents or bases and shows a wide scope, including pharmaceuticals and complex molecular architectures.

AbstractOff‐target toxicity and insufficient hydroxyl radicals (.OH) generation limit the further clinical application of nanozymes in chemodynamic therapy (CDT). Herein, we designed and constructed a microRNA‐triggered nanozyme cascade platform for enhanced tumor‐specific chemodynamic therapy. The nanozyme‐based cascade reaction could be triggered successfully by the high expression of microRNA in cancer cells to generate more .OH, thus exhibiting excellent tumor‐specific therapeutic performance. Our work provides a new dimension for tumor‐specific chemodynamic therapy.

AbstractIntroductionSuicidal thinking is relevant in patients with First Episode Psychosis (FEP). However, longitudinal studies specifically examining treatment response for suicidal ideation in FEP are still relatively scarce, especially with long‐term design and in real‐world clinical settings. The aims of this research were (A) to longitudinally assess suicidal thoughts in people with FEP along a 2‐year follow‐up period and (B) to overtime investigate any significant association of suicidal ideation levels with the specific treatment components of an ‘Early Intervention in Psychosis’ (EIP) protocol along the 2 years of follow‐up.MethodsAt entry, 232 FEP participants (aged 12–35 years) completed the Brief Psychiatric Rating Scale (BPRS), including a ‘Suicidality’ item subscore. Multiple linear regression analysis was then performed.ResultsAcross the follow‐up, FEP subjects showed a relevant decrease in suicidal thinking levels overtime. This was specifically predicted by the total number of individual psychotherapy sessions offered within the 2‐year EIP protocol and antidepressant dose (at least as regards the first year of our intervention).ConclusionSuicidal ideation is clinically relevant in FEP but seems to improve overtime together with the provision of specific, patient‐tailored and integrated EIP treatments, especially individual psychotherapy.
Load torque control of an electromagnetic motor with a reduction gear and motor/load‐side encoders using a spring model including a dead zone

Published: October 2021

AbstractActuators with characteristics such as light weight, a high torque/weight ratio, and a high torque control performance are desired for contact tasks using robots. Although electromagnetic motors with gears have these features, friction in gears degrades the torque control performance. Therefore, in this study, the load torque control performance is improved by utilizing motor/load side angle information. Both the torque controller and the load torque observer in the proposed control system utilize motor/load side encoders and the spring model, which includes a dead zone. The dead zone model represents the backlash between the motor output shaft and the reducer output shaft. A simulation and experiment show the efficacy of the proposed control system.
