AbstractPurposeMedical physics residents (MPRs) will define and shape the future of physics in medicine. We sought to better understand the residency experience, as related to resilience and well‐being, through the lens of current MPRs and medical physicists (MPs) working with residents.Methods and materialsFrom February–May 2019, we conducted 32, 1‐h, confidential, semi‐structured interviews with MPs either currently enrolled in an accredited residency (n = 16) or currently employed by a department with an accredited residency (n = 16). Interviews centered on the topics of mentorship, work/life integration, and discrimination. Qualitative analysis methods were used to derive key themes from the interview transcripts.ResultsWith regard to the medical physics residency experience, four key themes emerged during qualitative analysis: the demanding nature of medical physics residencies, the negative impacts of residency on MPRs during training and beyond, strategies MPRs use to cope with residency stress, and the role of professional societies in addressing residency‐related change.ConclusionsResidency training is a stress‐inducing time in the path to becoming a board‐certified MP. By uncovering several sources of this stress, we have identified opportunities to support the resiliency and well‐being of MPs in training through recommendations by professional societies, programmatic changes, and interventions at the department and residency program director level for residency programs, as well as strategies that MPRs themselves can use to support well‐being on their career journey.

Published: February 2022

AbstractAutoimmune glial fibrillary acidic protein astrocytopathy (GFAP‐A) is a steroid‐responsive meningoencephalomyelitis, sometimes presenting with atypical clinical signs such as movement disorders or psychiatric and autonomic features. Beyond clinical presentation and imaging, diagnosis relies on detection of GFAP‐antibodies (AB) in CSF. Using quantitative behavioral, serologic, and immunohistochemical analyses, we characterize two patients longitudinally over 18–24 months who presented with rapidly progressive neurocognitive deterioration in the context of GFAP‐AB in CSF and unremarkable cranial MRI studies. Intensified immunotherapy was associated with clinical stabilization. The value of GFAP‐AB screening in selected cases of rapidly progressive dementias is discussed.

Published: February 2022

AbstractA novel and versatile shape memory ink system allowing 4D printing with light at the macroscale as well as the microscale is presented. Digital light processing (DLP) and direct laser writing (DLW) are selected as suitable 3D printing technologies to cover both regimes. First, a system based on monofunctional isobornyl acrylate and two crosslinkers consisting of a soft and a hard diacrylate is identified and proven to be compatible with both printing techniques. Employing DLP, a large variety of structures exhibiting distinct complexity is printed. These structures range from simple frames to more demanding 3D geometries such as double platform structures, infinity rings, or cubic grids. The shape memory effect is demonstrated for all the 3D geometries. Excellent shape fixity as well as recovery and repeatability is shown. Furthermore, the formulation is adapted for fast 4D printing at the microscale using DLW. Importantly, the 4D printed microstructures display remarkable shape memory properties. The possibility of trapping and releasing microobjects, such as microspheres, is ultimately demonstrated by designing, smart box‐like 4D microstructures that can be thermally actuated—evidencing the versatility and potential of the reported system.

AbstractThe eye is one of the most complex organs in the human body, containing rich and critical physiological information (e.g., intraocular pressure, corneal temperature, and pH) as well as a library of metabolite biomarkers (e.g., glucose, proteins, and specific ions). Smart contact lenses (SCLs) can serve as a wearable intelligent ocular prosthetic device capable of noninvasive and continuous monitoring of various essential physical/biochemical parameters and drug loading/delivery for the treatment of ocular diseases. Advances in SCL technologies and the growing public interest in personalized health are accelerating SCL research more than ever before. Here, the current status and potential of SCL development through a comprehensive review from fabrication to applications to commercialization are discussed. First, the material, fabrication, and platform designs of the SCLs for the diagnostic and therapeutic applications are discussed. Then, the latest advances in diagnostic and therapeutic SCLs for clinical translation are reviewed. Later, the established techniques for wearable power transfer and wireless data transmission applied to current SCL devices are summarized. An outlook, future opportunities, and challenges for developing next‐generation SCL devices are also provided. With the rise in interest of SCL development, this comprehensive and essential review can serve as a new paradigm for the SCL devices.
Recent Trends in Waterborne and Bio‐Based Polyurethane Coatings for Corrosion Protection
Authors: Salzano de Luna Martina 
Published: February 2022

AbstractPolyurethanes (PUs) have been extensively exploited for the production of protective coatings thanks to the versatility of their chemistry, which allows to adjust the coating properties depending on the final application. In the last decade, the concerns on the negative impact on the environment and human health of traditional petroleum‐based and solvent‐borne PUs have fostered the research on more environmentally friendly alternatives. This review article provides an overview of the recent approaches that have been profitably pursued for the development of green PUs coatings for the protection of metal surfaces from corrosion. In particular, waterborne and bio‐based polyurethane coatings are addressed, highlighting the main strategies adopted to enhance their anticorrosion ability. Finally, relevant data on the protective performances of green PU coatings are collected and critically discussed.

Published: February 2022

AbstractIcing accretion on aircraft surfaces has threatened the flight safety so far. Slippery liquid infused porous surface (SLIPS) is an emerging anti‐icing method. Many studies have found that SLIPS has self‐repairing phenomena. However, there is almost no systematic research on the number of self‐repairs in service, which determines the durability of anti‐icing. Herein, the self‐repairing performance of SLIPS is studied through icing‐repairing and abrasion‐repairing cycles. A stable and smooth lubricating layer of SLIPS is obtained by infiltrating a silanized porous surface with silicone oil, and the porous surface is constructed by anodization. The SLIPS exhibits low ice‐adhesion strength even after frosting and the ice accumulation on the SLIPS can slide off under gravity. The self‐repairing properties are evaluated under the condition that the ice‐adhesion strength does not exceed 100 kPa. The SLIPS can withstand ≈150 icing/deicing cycles via 5 times of 1 h self‐repair and 100 abrasion cycles via 4 times of 1 h self‐repair. The results show that the SLIPS has durable anti‐icing properties. Therefore, the prepared SLIPS are promising in the field of durable aircraft anti‐icing materials.

Published: February 2022

AbstractHighly active and low‐cost anodic hydrogen oxidation reaction (HOR) catalysts play a significant role in the large‐scale application of anion exchange membrane fuel cells (AEMFCs). Herein, a novel anodic HOR electrocatalyst with RuP nanoparticles loaded on N, O codoped porous hollow carbon (RuP/NOC) is prepared. The catalyst exhibits high catalytic activity toward HOR, achieving a kinetic mass activity of 3.25 mA µg–1PGM at 50 mV, 13 times higher than that of Ru/NOC and even superior to that of Pt/C. Density functional theory (DFT) calculations demonstrate that the transfer of electrons from ruthenium to phosphorus shifts down the d‐band center of Ru, weakening the hydroxyl binding energy and decreasing the reaction energy barrier for HOR, thus enhancing the catalytic activity of Ru.

AbstractInterface engineering has become one of the most important research strategies to harness the full potential of perovskite solar cells. Photovoltaic community seems to herald the imminent development of 30% efficient perovskite devices with competitive lifetimes, subject, among other aspects, to clarify “what happens under the interfaces.” One of the most powerful techniques to characterize the intermixing ionic‐electronic processes that take place at perovskite interfaces is the Impedance Spectroscopy. It is a real fact that this methodology reveals the characteristic phenomenology attributed to interfacial phenomena, in form of complex spectra that interfere with a proper identification of dominant mechanisms. This article presents approaches to characterizing the non‐ideal electrical properties associated with the appearance of an interfacial capacitance distribution, identifying major sources of intrinsic/extrinsic origin and so, providing further progress in the understanding of phenomenological mechanisms of photovoltaic perovskites. Importantly, the study addresses the evolution of dispersive capacitance's characteristic parameters with light intensity (and bulk thickness), obtaining a useful alternative way of determining the ideality factor and thus, the recombination of charge carriers. The results are discussed in light of critical importance exhibited by the interactions between ionic and electronic species, with the aim of advancing in device efficiency and stability.

Published: February 2022

AbstractWastewater containing oil and surfactant pollution causes health, environment, and resource issues. Surfactant‐stabilized emulsion separation is conventionally achieved by modified sponges, membranes and micro‐nanoparticles, still, with relevant limitations in low durability, high energy consumption, and discontinuity. Inspired by nasal cavity, a superhydrophobic/superoleophilic nanowires decorated cone array tube with penetrated pores is demonstrated for oil recovery in micron‐sized oil‐in‐water emulsions. The experimental results reveal that the separation efficiency can reach 99.84% and the oil recovery efficiency can achieve 92% at the same time. Oil droplets are captured by cones under the synergy of superwettability and gradient structure, and then transport driven by the force of Laplace pressure. The whole process of oil recovery in wastewater is continuous, durable, and versatile for different oil/surfactant contents. This work will effectively control wastewater pollution and facilitate oil resource recovery, and opens the possibility of phase separation in various applications, such as chip microfluidics, beverage refining, and drug screening.

AbstractIn this study, the radiation effects of electron beam (e‐beam) on field‐effect transistors (FETs) using transition‐metal dichalcogenides (TMD) as a channel are carefully investigated. Electron‐hole pairs (EHPs) in SiO2 generated by e‐beam irradiation induce additional traps, which change the surface potential of the TMD channel, resulting in strong negative shifts of transfer characteristics. These negative shifts, which remind one of n‐doping effects, are highly affected not only by the condition of e‐beam irradiation, but also by the gate bias condition during irradiating. As a result of the e‐beam irradiation effect, band bending and contact resistance are affected, and the degree of formation of oxide traps and interface traps varies depending on the gate bias conditions. In the case of VG > 0 V application during e‐beam irradiation, the negative shifts in the transfer characteristics are fully recovered after ambient exposure. However, the interface traps increase significantly, resulting in variations of low‐frequency (LF) noise and time‐dependent current fluctuations.

AbstractThe insect resistance of Bacillus thuringiensis (Bt) transgenic rice (Oryza sativa L.) is mainly determined by the transcription of the CRY1C gene and the translation process of the Cry1C protein. With this in mind, we analyzed CRY1C expression and Cry1C protein content in a transgenic Bt insect‐resistant restorer line and its F1 hybrids, evaluated the resistance to Chilo suppressalis of various lines of rice, and determined the 50% lethal concentration (LC50) of Cry1C for C. suppressalis. In four transgenic rice lines, the relative expression of CRY1C was highest at the heading stage in most tissues. Among different tissues from the same developmental stage, CRY1C expression was highest in leaves, followed by stems and panicles. The relative expression of CRY1C was higher in the parent restorer line than in the F1 hybrids. The LC50 of the Cry1C protein for C. suppressalis was 4.016 μg g−1, and the Cry1C protein expression level of transgenic insect‐resistant rice exceeded this threshold at the heading stages and in stems. We next analyzed the lethality of each strain toward C. suppressalis. After 48 h, the mortality rate of second‐instar C. suppressalis larvae feeding on transgenic stem tissue was higher at the heading stage than at the tiller stage and varied from 66.7 to 91.7%. By documenting the temporal and spatial expression of CRY1C and evaluating C. suppressalis resistance to Bt transgenic rice, the risk of pests and diseases during the rice production process can be greatly reduced.
From FAIR to FAIRS: Data security by design for the global burden of animal diseases
Authors: Stacey Deborah , Wulff Kenneth , Chikhalla Nidhip , Bernardo Theresa 
Published: February 2022

AbstractSolving complex global problems involving data and data analysis can require data from both the public and private sectors. The sharing of data has traditionally been restricted to open data. To facilitate the use of both open and private data, a new data‐sharing framework has been constructed as an extension to the popular Findable‐Accessible‐Interoperable‐Reusable (FAIR) framework. The “Secure by Design” approach has been taken to define the FAIRS data‐sharing framework where S stands for Secure. A Cloud infrastructure architecture is proposed that would allow data brokers to implement FAIRS. This architecture is being constructed for the Global Burden of Animal Diseases (GBADs) to facilitate the sharing of livestock data.

Published: February 2022

AbstractThe liquid thermal conductivity of the ionic liquid (IL), 1‐hexyl‐3‐methyl‐imidazolium bis(trifluoromethylsulfonyl)amide ([HMIm][Tf2N]), saturated with compressed vapor and supercritical carbon dioxide was measured over three isotherms (298.15, 323.15, and 348.15 K) and pressures up to approximately 20 MPa using a transient hot‐wire technique. Pure [HMIm][Tf2N] thermal conductivity was also measured over a temperature range of 293.15–353.15 K at ambient pressure and with hydrostatic pressure to approximately 20 MPa. Literature vapor–liquid equilibrium data were used to predict the liquid CO2 composition at the conditions investigated. Initially, the liquid thermal conductivity slightly decreased with pressure/composition of CO2 followed by a gradual increase that is mainly attributed to hydrostatic pressure effects. Simple composition‐based mixing rules for mixture properties are not qualitatively nor quantitatively accurate. These data could be used to engineer heat transfer equipment required for a variety of proposed IL applications in CO2 capture, absorption refrigeration, biphasic CO2/IL reaction platforms, etc.

AbstractThe application of photochemistry in polymer synthesis is of interest due to the unique possibilities offered compared to thermochemistry, including topological and temporal control, rapid polymerization, sustainable low‐energy processes, and environmentally benign features leading to established and emerging applications in adhesives, coatings, adaptive manufacturing, etc. In particular, the utilization of photochemistry in controlled/living polymerizations often offers the capability for precise control over the macromolecular structure and chain length in addition to the associated advantages of photochemistry. Herein, the latest developments in photocontrolled living radical and cationic polymerizations and their combinations for application in polymer syntheses are discussed. This Review summarizes and highlights recent studies in the emerging area of photoinduced controlled/living polymerizations. A discussion of mechanistic details highlights differences as well as parallels between different systems for different polymerization methods and monomer applicability.

Published: February 2022

AbstractThe rational development of an anion templation strategy for the construction of macrocycles has been historically limited to small anions, but large polyoxoanions can offer unmatched structural diversity and ample binding sites. Here we report the formation of a {Mo22Fe8} macrocycle by using the Preyssler anion, [NaP5W30O110]14− ({P5W30}), as a supramolecular template. The {Mo22Fe8} macrocycle displays selective anion binding behavior in solution. In the solid state, the 1 : 2 host–guest complex, {P5W30}2⊂{Mo22Fe8}, transports protons more effectively, through an extended hydrogen‐bonding network, than a related 1 : 1 complex where the guest is completely encapsulated. The results highlight the great potential this anion templation approach has in producing macrocyclic systems for selective anion recognition and proton conduction purposes.

Published: February 2022

AbstractMelt electrospinning writing (MEW) has proven its potential to direct‐write complex and multiscaled architectures and structures, which are widely used in the biomedical fields such as 3D printing of porous scaffolds. For the resolution of the microstructure is characterized by the diameter of the melt electrospun fiber, uniform spinning fiber with predictable diameter is of great significance for precise fabrication of the microstructure. In this paper, the Kriging model was introduced to explore the scaling laws of the fiber diameter to several processing parameters (including temperature, tip‐to‐collector distance, flow rate, and collector speed). The Latin hypercube sampling was adopted for experiment design. The prediction results of the Kriging model were cross‐validated with the response surface model to compare the prediction accuracy of the two methods. The root‐mean‐square error, maximum absolute error, and mean absolute percentage error of the Kriging model (0.49%, 0.73%, and 3.52%, respectively) are all lower than the response surface model (0.81%, 1.25%, and 4.74%, respectively), indicating that the prediction accuracy of the Kriging model is superior to the response surface model. The present paper provides a new idea for the modeling of the complex nonlinear system of MEW. Moreover, the implementation of the Kriging model minimizes the number of experimental trials required from 31 to 27, resulting in the reduction of the fabrication time and materials wastage.
