AbstractThe storage capacity of carbon dioxide (CO2) on the wet SBA‐15 material can be greatly improved by forming gas hydrates. The presence of generous polar groups (hydroxyl groups) on the surface of SBA‐15 hinders the formation of CO2 hydrates. In order to further improve its CO2 adsorption capacity, the polar surfaces of SBA‐15 material are changed into non‐polar carbon surfaces by covering with carbon film, and Si−C composite is obtained. Compared with the SBA‐15 material, the pore size and pore volume of the Si−C composite material reduces but its morphology and structure are unchanged. Whether pre‐adsorbed water or not, the experiment results showed that the Si−C composite material is more conducive to the adsorption of CO2 than the SBA‐15 material. In a comparison of the Si−C composite material and the SBA‐15 material at 2.5 MPa, the CO2 adsorption capacity increased from 3.8 mmol/g to 8.5 mmol/g with dry samples, and the CO2 adsorption capacity increased from 20.1 mmol/g to 26.9 mmol/g with wet samples at Rw=2.0.

AbstractElectrochemical sodium‐ion storage technologies have become an indispensable part in the field of large‐scale energy storage systems owing to the widespread and low‐cost sodium resources. Molybdenum carbides with high electron conductivity are regarded as potential sodium storage anode materials, but the comprehensive sodium storage mechanism has not been studied in depth. Herein, Mo2C nanowires (MC‐NWs) in which Mo2C nanoparticles are embedded in carbon substrate are synthesized. The sodium‐ion storage mechanism is further systematically studied by in/ex situ experimental characterizations and diffusion kinetics analysis. Briefly, it is discovered that a faradaic redox reaction occurs in the surface amorphous molybdenum oxides on Mo2C nanoparticles, while the inner Mo2C is unreactive. Thus, the as‐synthesized MC‐NWs with surface pseudocapacitance display excellent rate capability (a high specific capacity of 76.5 mAh g−1 at 20 A g−1) and long cycling stability (a high specific capacity of 331.2 mAh g−1 at 1 A g−1 over 1500 cycles). The assembled original sodium ion capacitor displays remarkable power density and energy density. This work provides a comprehensive understanding of the sodium storage mechanism of Mo2C materials, and constructing pseudocapacitive materials is an effective way to achieve sodium‐ion storage devices with high power and energy density.

AbstractOral cancer has a high mortality rate, and its treatment often causes debilitating complications. More than 90% of oral cancers are oral squamous cell carcinomas (OSCCs) that may develop from clinically recognizable oral premalignant lesions (OPLs). To eradicate OPLs before they turn into cancers, a non‐invasive topical formulation is developed based on a novel combination of synergistically acting oxaliplatin (OXP) and mycophenolate (MPS) embedded in a controlled‐release mucoadhesive patch fabricated by computer‐aided 3D printing. After multiple rounds of testing and optimization, a v6.4 ChemoPatch is designed, which shows sustained release of OXP and MPS in vitro, minimal side leakage of drugs, an average elastic modulus of 2.38 MPa, and suitable drug stability at 4 °C or below for up to 12 months. In vivo analyses show almost all patches adhere to the dorsal tongue surface for 4 hours, and display a sustained release of OXP and MPS to tongue tissue for 3–4 hours. When applied in the 4‐nitroquinoline‐1‐oxide‐induced OPL rat model, the OXP‐MPS patch significantly ablates dysplastic lesions with no damage to normal epithelial cells and minimal systemic absorption and side effects. This study reports the design of a novel mucoadhesive ChemoPatch as a noninvasive therapy to treat OPLs.

Published: May 2022

AbstractElectrochemical overall water splitting using renewable energy input is highly desirable for large‐scale green hydrogen generation, but it is still challenged due to the lack of low‐cost, durable, and highly efficient electrocatalysts. Herein, 1D nanowires composed of numerous 2 nm Co0.85Se‐NiSe nanograin heterojunctions as efficient precious metal‐free bifunctional electrocatalyst are reported for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) in alkaline solution with the merits of high activity, durability, and low cost. The abundant microinterface among the ultrafine nanograins and the presence of lattice distortion around nanograin interface is found to create a superhydrophilic surface of the electrocatalyst, which significantly facilitate the fast diffusion of electrolytes and the release of the formed H2 and O2 from the catalyst surface. Furthermore, synergic effect between Co0.85Se and NiSe grain on adjusting the electronic structure is revealed, which enhances electron mobility for fast electron transport during the HER/OER process. Owing to these merits, the rationally designed Co0.85Se‐NiSe heterostructures display efficient overall water splitting behavior with a low voltage of 1.54 V at 10 mA cm−2 and remarkable long‐term durability for the investigated period of 50 h.

Published: May 2022

AbstractTetralogy of Fallot with atresia of the pulmonary artery (ToF‐PA) is a rare congenital cardiac malformation. The life expectancy of affected canine individuals is short: in fact, only puppies or young adults with ToF‐PA are described in literature. Typically, these patients require general anaesthesia for diagnostic procedures, and are considered at high risk for anaesthesia‐related complications. The present report describes successful anaesthesia for dental surgery of a 12‐year‐old dog affected by ToF‐PA and an extracardiac shunting vessel connecting aorta and pulmonary artery. The echocardiographic findings are described and the anaesthetic protocol and the complications encountered during anaesthesia are discussed.

Published: May 2022

AbstractThe growing demands to mitigate climate change and environmental degradation stimulate the rapid developments of rechargeable lithium (Li) battery technologies. Fast Li transports in battery materials are of essential significance to ensure superior Li dynamical stability and rate performance of batteries. Herein, the Li transport mechanisms in solid‐state battery materials (SSBMs) are comprehensively summarized. The collective diffusion mechanisms in solid electrolytes are elaborated, which are further understood from multiple perspectives including lattice dynamics, crystalline structure, and electronic structure. With the exponentially improving performance of computers, atomistic simulations have been playing an increasingly important role in revealing and understanding the Li transport in SSBMs, bridging the gap between experimental phenomena and theoretical models. Theoretical and experimental characterization methods for Li transports are discussed. The design strategies toward fast Li transports are classified. Finally, a perspective on the achievements and challenges of probing Li transports is provided.This article is categorized under:

Published: May 2022

AbstractUrban agriculture provides a promising, comprehensive solution to water, energy, and food scarcity challenges resulting from the population growth, urbanization, and the accelerating effects of anthropogenic climate change. Their close access to consumers, profitable business models, and important roles in educational, social, and physical entertainment benefit both developing and developed nations. In this sense, Urban Water Resource Reclamation Facilities (WRRFs) can play a pivotal role in the sustainable implementation of urban agriculture. Reclaimed water as a recovered resource has less supply variability and in certain cases can be of higher quality than other water sources used in agriculture. Another recovered resource, namely, biosolids, as byproduct from wastewater treatment can be put to beneficial use as fertilizers, soil amendments, and construction material additives. The renewable electricity, heat, CO2, and bioplastics produced from WRRFs can also serve as essential resources in support of urban agriculture operation with enhanced sustainability. In short, this review exhibits a holistic picture of the state‐of‐the‐art of urban agriculture in which WRRFs can potentially play a pivotal role.Practitioner Points

Published: May 2022

AbstractAs an inexpensive and non‐toxic binary layered compound, SnS shows great potential in thermoelectric applications. In this work, we performed a systematical study on how minute co‐doping of Ag, Sb and Se in a mole ratio of 1 : 1 : 2 (namely AgSbSe2) affects thermoelectric transport properties of p‐type SnS. It is found that AgSbSe2 has a high solid solution limit (at least 4 mol %) in the matrix, and the band gap of SnS gets reduced upon Ag, Sb and Se co‐doping. The strong anharmonic chemical bonding and reinforced point defect scattering synergistically contribute to a low thermal conductivity of ∼0.88 W m−1 K−1 at room temperature for the sample Sn0.92Ag0.04Sb0.04S0.92Se0.08. An abnormal decrease of hole concentration in the co‐doped SnS is established, which is attributed to the generation of more Sn4+ ions in the lattice. Fine tuning of Ag/Sb ratio might populate more charge carriers and yield higher thermoelectric performance.
Numerical solution of magnetohydrodynamics radiative flow of Oldroyd‐B nanofluid toward a porous stretched surface containing gyrotactic microorganisms
Authors: Khan Muhammad Riaz , Mao Shipeng 
Published: May 2022

AbstractIn this article, we explore an incompressible steady flow of Oldroyd‐B nanofluid near a plan porous stretched surface considering the influence of thermophoresis, Brownian motion, and thermal radiation. Moreover, the constant magnetic field of intensity B0 is implemented with a low Reynolds number as well as the induced magnetic effect and the electric fields are ignored. The suitable similarity variables are applied to the governing partial differential equations (PDEs) which yield the dimensionless ordinary differential equations (ODEs). The MATLAB function bvp4c has been used to resolve the resulting ODEs. The attributes of various flow parameters on the transfer rate of mass, heat, density number of motile microorganisms, motile density, temperature, velocity, and nanoparticles concentration have been explored. It is determined that the boosting values of Prandtl number, solutal stratified, and the radiation parameter supports the boosting of heat transfer rate, and their reduction is assisted by the boosting values of thermal stratified and Brownian motion parameter. Moreover, the higher values of Brownian motion parameters and Schmidt number are more effective in the boosting of Sherwood number, although an opposite behavior is spotted for the boosting values of the thermophoresis and solutal stratified parameter. In the same way, the fluid velocity declines with the escalation of Deborah numbers, Hartmann number, and porosity parameter as well as the fluid temperature minimizes for the inclination of Prandtl number and thermal stratified parameter although it is magnified for the inclination of radiation parameter.

AbstractTactile sharing with others facilitates improving communications and augmenting cooperative tasks. An increase of persons sharing tactile sensations increases the effectiveness whereas the area of tactile stimuli given should be investigated for intuitive perception. This study investigated the effect of spatial correspondence between tactile and visual stimuli in identifying tactile stimuli. In the experiment, participants viewed simultaneously two videos of other agents’ hands each rubbing one of three textures and felt their vibrotactile stimuli in two locations. The videos were presented at different locations on the screen (Scene 1$$:$$:left-right side or Scene 2 & 3$$:$$:top-bottom) and the vibrotactile stimuli were presented either at the wrists of the left and right hand (Scene 1) or at the upper arm and the wrist of the right arm which either rested on the table (Scene 2) or was hanging down along the body (Scene 3). For each scene, visual and tactile stimuli were either spatially aligned (left and right video with tactile stimuli at the left and right wrist, and top and bottom video with top and bottom location on the right arm) or not. The result showed shorter response times for left-right spatial correspondence and for far (top) and close (bottom) visual stimuli corresponding to distal (wrist) and proximal (upper arm) locations on the body. This implied that the body schematic is an important factor for spatial compatibility of visual and tactile stimuli.

AbstractThe sense of touch plays a strong role in the perception of the properties and characteristics of hollow objects. The action of shaking a hollow container to get an insight of its content is a natural and common interaction. In this paper, we present a multi-modal rendering approach for the simulation of virtual moving objects inside a hollow container, based on the combination of haptic and audio cues generated by voice-coils actuators and high-fidelity headphones, respectively. We conducted a user study. Thirty participants were asked to interact with a target cylindrical hollow object and estimate the number of moving objects inside, relying on haptic feedback only, audio feedback only, or a combination of both. Results indicate that the combination of various senses is important in the perception of the content of a container.
A Database of Vibratory Signals from Free Haptic Exploration of Natural Material Textures and Perceptual Judgments (ViPer): Analysis of Spectral Statistics
Authors: Toscani Matteo , Metzger Anna 
Published: May 2022

AbstractWe recorded vibratory patterns elicited by free haptic exploration of a large set of natural textures with a steel tool tip. Vision and audio signals during the exploration were excluded. After the exploration of each sample, participants provided judgments about its perceptual attributes and material category. We found that vibratory signals can be approximated by a single parameter in the temporal frequency domain, in a similar way as we can describe the spatial frequency spectrum of natural images. This parameter varies systematically between material categories and correlates with human perceptual judgements. It provides an estimate of the spectral composition of the power spectra which is highly correlated with the differential activity of the Rapidly Adapting (RA) and Pacinian Corpuscle (PC) afferents.
Neutral Point in Haptic Perception of Softness
Authors: Metzger Anna , Lotz Anna , Drewing Knut 
Published: May 2022

AbstractHaptic perception of objects’ softness plays an important role in the identification and interaction with objects. How softness is represented in the brain is yet not clear. Here we investigated whether there is a neutral point in the perceptual representation of haptically perceived softness relative to which the objects are represented as being “soft” or “hard”. We created a wide range of softness stimuli, varying from very hard (ceramic) to very soft foam with differently soft foam and silicone stimuli in between. Participants were assigned to one of three different stimulus set conditions: full set (18 stimuli), soft set (13 softest stimuli) or the hard set (13 hardest stimuli). They categorized each stimulus as “hard” or “soft” and we estimated the neutral point as the point of subjectively equal categorization as “hard” or “soft”. We found that neutral points were different from the middle stimulus of each set. Furthermore, during the course of the experiment neutral points rather moved away from the middle of the stimulus set than towards it. Our results indicate that there might be a neutral point in the representation of haptically perceived softness, however range effects may play a role.
Holographic complexity in dSd+1

Published: May 2022

Abstract
We study the CV, CA, and CV2.0 approaches to holographic complexity in (d + 1)-dimensional de Sitter spacetime. We find that holographic complexity and corresponding growth rate presents universal behaviour for all three approaches. In particular, the holographic complexity exhibits ‘hyperfast’ growth [1] and appears to diverge with a universal power law at a (finite) critical time. We introduce a cutoff surface to regulate this divergence, and the subsequent growth of the holographic complexity is linear in time.
Indexing, enriching, and understanding Brazilian missing person cases from data of distributed repositories on the web

Published: May 2022

AbstractFor decision making in government, it is necessary to have well-structured sources of information. In several countries, it is difficult to access government data as the information are dispersed, disconnected, and poorly structured. For this reason, this work presents a framework to gather, unify, and enrich missing person data from distributed web sources. The framework allows inserting new tasks specific to the user’s domain to improve data quality. In this study, Brazilian missing person data from non-governmental organizations (NGOs) and governmental websites were collected and semantically enriched. To enhance the understanding of the gathered missing people cases, we create interpretive models using machine learning techniques to extract knowledge and to encourage the use of standards for publishing the data that are frequently ignored by organizations, hindering analysis and decision-making on data. After the collection and semantic enrichment process, there was an increase of approximately 11% in the data present in the base. Also, the mining process evidenced the disappearance and reappearance of a person in Brazil according to several factors such as age, state initiatives, skin tone, hair colors, etc.
Self-employment career patterns in the Netherlands: exploring individual and regional differences
Authors: Bay Franziska , Koster Sierdjan 
Published: May 2022

AbstractAlthough the self-employed represent 16.7% of the Dutch labor force (OECD 2020), their internal heterogeneity in profiles regarding motivations, characteristics and career trajectories remains unclear. Yet, understanding self-employment profiles and their spatial distribution may help understand differences in career progression of the self-employed. This study identifies and describes patterns in long-term career trajectories of the Dutch self-employed, and it explores spatial differences along the urban hierarchy. The study uses a life-course approach and register data of the whole population to find common patterns of careers among a sample of Dutch self-employed (N = 42,028) and their spatial distribution. We investigated careers through sequence and cluster analysis of individuals’ socio-economic statuses between 2003–2018. The analysis identifies 7 career clusters that collapse into three main career profiles: Mixed self-employment careers that combine self-employment with wage-employment, stable self-employment, and precarious self-employment. The clusters differ importantly in terms of the individual characteristics of the self-employed including age, gender, educational level and income. In terms of spatial distribution, the study shows that self-employment career profiles follow the urban hierarchy. Urban regions give way to all types of self-employment, while rural regions mainly exhibit stable self-employment. Precarious self-employment presents differently in urban and rural areas; in urban labor markets, we find self-employed individuals vulnerable to economic shocks, losing their jobs as a consequence of the financial crisis in 2007/08. In rural regions, formerly inactive workers become self-employed following the crisis.
Raman spectroscopy and multivariate analysis as potential tool to follow Alzheimer’s disease progression

Published: May 2022

AbstractRaman spectroscopy is an emerging tool in the research and diagnosis of different diseases, including neurodegenerative disorders. In this work, blood serum samples collected from healthy controls and dementia patients were analysed by Raman spectroscopy to develop a classification model for the diagnosis of dementia of Alzheimer’s type (DAT). Raman spectra were processed by means of multivariate tools for multivariate analysis. Lower concentration levels of carotenoids were detected in blood serum from patients, which allowed for a good discrimination with respect to controls, such as 93% of correct predictions on the test set with random forest. We also hypothesize that carotenoid levels might be informative about the severity and progression of the disease, since the intensity of carotenoid signals decreased from the early stage to more severe patients. These encouraging results suggest the possibility to use Raman spectroscopy for the analysis of alternative biofluids (e.g. saliva) and the unobtrusive diagnosis of other neurodegenerative disorders.
