First-principles calculation of X-ray photoelectron spectroscopy binding energy shift for nitrogen and phosphorus defects in 3C-silicon carbide
Authors: Matsushima Naoki , Yamauchi Jun 
Published: April 2019

Abstract
We systematically investigated the formation energies and the core-level X-ray photoelectron spectroscopy binding energy (XPSBE) shifts of nitrogen (N) 1s and phosphorus (P) 2p for defects including N and P in 3C-SiC by a first-principles calculation using the generalized gradient approximation, whose reliability for n-type defects was confirmed by some tests using the HSE06 hybrid functional. XPSBEs were separated into the local potential average around the impurity and the relaxation energy of the wave function to analyze the relationship between the XPSBE shift and the defect structures. It is difficult to understand the relaxation energy intuitively. The electrons localized around the impurity atom, which have energy levels in energy gaps, make a large contribution to the relaxation energies. Considering the formation energies, we predicted some XPS peaks expected to be found.

Published: April 2019

AbstractElectronic device versions of the neural functions of the human retina have high potential for use in artificial vision. This study demonstrates halide perovskite artificial human photoreceptors with specific photoresponses to red, green, and blue colors, which are consistent with human retinal photoreceiving cones and rods. In contrast to the current programmable spectral‐response technologies, a novel microcavity structure is combined in this study with a perovskite absorber to achieve a targeted spectrum without using external optical filters. The fabricated artificial photoreceptors exhibit excellent performance including a high detectivity of more than 1013 Jones, a large linear dynamic range of 154 dB, and a short response time of 580 ns. These values are equal to or better than those of the natural human retina. These devices can easily be monolithically integrated on a single flexible substrate by using vacuum deposition, and a true proof‐of‐concept full‐color image reconstruction is demonstrated.

Published: April 2019

AbstractMethylammonium lead iodide perovskite, CH3NH3PbI3, has attracted particular attention due to its fast increase in efficiency for solid‐state solar cells application. However, little is known about the influence of dipole moments of organic molecules on the electronic structures. In this study, first principles calculations are carried out to investigate the stability and electronic property of series structures with the different distributions of organic molecules and vacancy defects. The calculated results suggest that the configurations with the opposite dipole moments of MA+ toward the PbI2 layers can greatly enhance the charge separation, which is caused by the local electric fields of dipole MA+ ions. The direction and interval of localized charge are greatly dependent on the distribution of the MA+ ions. Furthermore, the configurations with the opposite dipole of the MA+ ions facing the PbI2 can be stabilized by vacancy defects.

AbstractThe protonation and magnetism effects on the spin transport properties of benzo[b]phenazine (BPE) and bis(o‐phenylenediamine) manganese (IV) complex (Mn‐OPD) molecules in series and in parallel are theoretically investigated using density functional theory (DFT) combined with nonequilibrium Green's function method (NEGF). The spin‐resolved current‐voltage curves show that the magnetic field mainly regulate the spin‐polarized direction of current, and the protonation effect will significantly reduce the magnitude of spin‐polarized current. Moreover, under two orthogonal inputs, the molecular combinational circuits can behave as AND and OR spin logic gates, suggesting the application potential of integrating logic operations for future spin‐based nanoelectronics. In addition, we have observed the Fano resonance phenomenon in the parallel molecular junction, and the Fano resonance feature can be canceled by protonation effect. This work proposes a feasible way to construct a complex single‐molecule spin logic gate device.

Published: April 2019

BackgroundVentricular septal perforation (VSP) can be caused by a penetrating cardiac injury. Diagnosis of VSP tends to be delayed because a shunt might not be detected by color flow Doppler at an early stage following injury.Case presentationA 60‐year‐old man with depression was admitted to the emergency center after a knife injury in the chest. A focused assessment with sonography for trauma revealed cardiac tamponade. Shortly after an open cardiac massage and a pericardiotomy, his spontaneous circulation returned. At a later stage, follow‐up computed tomography, echocardiography, and left ventriculography showed traumatic ventricular septal perforation. Conservative therapy was chosen because the pulmonary blood flow/systemic blood flow ratio was 1.42.ConclusionThe initial contrast computed tomography shows a septal hematoma. Its presence could be perceived as a perforation site in the interventricular septum.

AbstractTechniken der molekularen Absorptionsspektroskopie liefern einzigartige Informationen über die innere Zusammensetzung biologischer Materie, indem sie die charakteristischen Infrarot‐Vibrationsbanden der beteiligten Moleküle detektieren. Durch den Einsatz von nanophotonischen Antennen und Metaoberflächen lässt sich einfallendes Licht auf der Nanoskala bündeln, was zu starker Licht‐Materie‐Wechselwirkung führt und es erlaubt, dieses Sensorkonzept bis hin zur Detektion weniger Moleküle auszudehnen. In diesem Kurzaufsatz werden wir neuartige Metaoberflächen‐basierte Ansätze der molekularen Biosensorik vorstellen und mit traditionellen Konzepten vergleichen. Ein besonderes Augenmerk liegt auf der kürzlich eingeführten Kombination von dielektrischen Metaoberflächen mit bildgebender Detektion, sowie auf dem Potential von künstlicher Intelligenz für das Design nanophotonischer Sensoren und die Datenanalyse. Solche Methoden erlauben die Messung molekularer Signaturen ohne Verwendung klassischer IR‐Spektrometer oder durchstimmbarer Laserquellen und stellen somit einen Durchbruch für miniaturisierte Sensoren in der Umweltanalytik und der patientennahen Labordiagnostik dar.

Published: April 2019

AbstractAlthough carborane‐based luminescent materials have been studied for years, no persistent phosphor has been reported so far. Herein, we describe boron‐cluster‐based persistent phosphors obtained by linking a σ‐aromatic carboranyl cage to the π system of a carbazolyl group. The carboranes were found to promote intersystem crossing from a singlet to a triplet state. The rigid boron cluster was able to stabilize the ultralong triplet excitons through multiple nonclassical hydrogen bonds, such as B−H⋅⋅⋅π interactions, thus leading to a long lifetime of up to 0.666 s and an absolute phosphorescence quantum yield of 7.1 %, which is outstanding for an organic phosphor without heavy atoms. These phosphors can be excited by visible light and show dynamic emission behavior, including thermochromism and mechanochromism. This study demonstrates that non‐metal/heavy‐atom boron clusters can be used to develop multifunctional high‐performance phosphors for potential applications.

Published: April 2019

AbstractMolecular spectroscopy provides unique information on the internal structure of biological materials by detecting the characteristic vibrational signatures of their constituent chemical bonds at infrared frequencies. Nanophotonic antennas and metasurfaces have driven this concept towards few‐molecule sensitivity by confining incident light into intense hot spots of the electromagnetic fields, providing strongly enhanced light‐matter interaction. In this Minireview, recently developed molecular biosensing approaches based on the combination of dielectric metasurfaces and imaging detection are highlighted in comparison to traditional plasmonic geometries, and the unique potential of artificial intelligence techniques for nanophotonic sensor design and data analysis is emphasized. Because of their spectrometer‐less operation principle, such imaging‐based approaches hold great promise for miniaturized biosensors in practical point‐of‐care or field‐deployable applications.

Published: April 2019

AbstractFunctional precision polymers based on monodisperse oligo(N‐substituted acrylamide)s and oligo(2‐substituted‐α‐hydroxy acid)s have been synthesized. The discrete sequences originate from a direct translation of side‐chain functionality sequences of a peptide with well‐studied properties. The peptide was previously selected to solubilize the photosensitizer meta‐tetra(hydroxyphenyl)chlorin. The resulting peptidomimetic formulation additives preserve the drug solubilization and release characteristics of the parent peptide. In some cases, superior properties are obtained, reaching up to 40 % higher payloads and 27‐times faster initial drug release.
Intrinsic flame‐retardant epoxy resin composites with benzoxazine: Effect of a catalyst and a low curing temperature

Published: April 2019

ABSTRACTThree kinds of inherent flame‐retardant epoxy resin (EP) composites with 20 wt % benzoxazine (BOZ) were prepared with different curing processes with 2‐methyl‐1H‐imidazole (MI) as a catalyst or/and changes in the curing temperature. The effects of the curing process on the flame retardancy, thermal stability, mechanical properties, and curing behaviors were investigated. The composite with added MI cured at low temperature (EBM–LT) had the best properties. It possessed a 35.3% limiting oxygen index and achieved a UL 94 V‐0 rating. Thermogravimetric analysis indicated that EBM–LT had the best thermal stability among the three kinds of EP composites with BOZ. The EP composites with BOZ mainly displayed a condensed‐phase flame‐retardant mechanism. The mechanical properties improvement was attributed to the formation of a heterogeneous network. Differential scanning calorimetry indicated that MI reacted with EP and catalyzed the homopolymerization of BOZ, and EP reacted with BOZ. Fourier transform infrared spectroscopy analysis indicated that curing at lower temperature caused the formation of more homopolymers of BOZ. The relationship of the curing process, network structure, and properties of EP composites with BOZ was established; this could help with the design of high‐performance EP composites with BOZ. © 2019 Wiley Periodicals, Inc.

Published: April 2019

ABSTRACTPolyethylene glycol (PEG) and pH‐sensitive polymers have been widely utilized in anticancer drug delivery systems due to their characteristics of prolonging circulation time and tumor‐responsive drug release. However, the effect of PEG molecular weight on the delivery of anticancer drug‐encapsulating pH‐sensitive polymer micelles has been poorly studied. Therefore, a simple method was used to prepare pH‐sensitive doxorubicin (DOX)‐loaded micelles (DOX/POD) based on polyethylene glycol‐2‐(octadecyloxy)‐1, 3‐dioxan‐5‐amine (POD) polymers, and the influence of PEG molecular weights (1 K, 2 K, and 5 K) on in vitro drug release and antitumor effect was further studied. Interestingly, as the molecular weight increased, the release amount of DOX was augmented. While the cytotoxicity and cellular uptake were increased, the molecular weight was decreased. It is reasonable to speculate that the high molecular weight of PEG may promote the dissolution rate of DOX, and their micelles with uncompact structure are being prone to disassembly in an acid environment. However, the low molecular weight of PEG may contribute to the formation of compact POD micelles, which make it easier to be uptaken by tumor cells resulting in the enhanced antitumor effect. Taken together, the results indicate that pH‐sensitive POD micelles with low molecular weight can achieve the efficient delivery of drugs, and PEG molecular weight in pH‐sensitive nanocarriers may influence the antitumor effect. © 2019 Wiley Periodicals, Inc.

Published: April 2019

AbstractResidual pollutants in the water treatment process restrict the advanced treatment and purification of wastewater, because most of them have stable structures, and some are not easily to be enriched. Photocatalytic oxidation technology can directly use solar energy to drive a series of chemical reactions, which has advantages such as low energy consumption, mild reaction conditions and rarely secondary pollution. It is an effective way to solve the organic pollution problem in wastewater treatment. The key to this process is to find and design efficient photocatalysts. The current photocatalytic materials mainly include inorganic semiconductors and metal organic frameworks (MOFs). They have been studied for pollutants degradation, hydrogen evolution, CO2 reduction, and organic transformation. But, most of these catalysts have not been used in real application. In this paper, recent research advances in MOFs photocatalysts and the key factors affecting their photocatalytic efficiency were critically reviewed. It is believed that the pursuit of more efficient photocatalyst needs to be considered from the adsorption‐photocatalytic mechanism, redox‐free radical mechanism, valence‐level regulation mechanism and energy transfer mechanism of photocatalysis. It is very necessary to research and develop nanoscale and quantum level mixed valence MOFs photocatalysts, which are constructed by strong electron‐donating groups.

Published: April 2019

AbstractOxygen reduction is a significant cathodic reaction in the state‐of‐art clean energy devices such as fuel cell and metal–oxygen battery. Here, ZIF‐incorporated hybrid polymeric fibres have been fabricated by using a dual‐phase electrospinning method. These are then transformed into Co3O4‐nanoparticle‐decorated porous N‐doped carbon fibres (ZIF‐Co3O4/NCF) through multi‐step annealing treatment. The resultant ZIF‐Co3O4/NCF is interweaved into a self‐supported film and can be used as a bi‐functional catalyst for catalysing oxygen reduction in both aqueous and non‐aqueous electrolytes. Electrochemical tests demonstrate that ZIF‐Co3O4/NCF displays a high catalytic activity for oxygen reduction with a half‐wave potential (E1/2) of 0.813 V (vs. RHE) and an almost favourable four‐electron reduction pathway in alkaline medium. ZIF‐Co3O4/NCF catalyst only shows 4 mV negative shift of E1/2 after 5000 continuous CV cycles. In addition, the ZIF‐Co3O4/NCF can be applied as the cathode catalyst of non‐aqueous Li–O2 battery, exhibiting a remarkable ORR activity in LiPF6 contained 1,2‐dimethoxyethane electrolyte. The excellent electrocatalytic performance of ZIF‐Co3O4/NCF is probably due to the abundance of active sites of graphitic carbon‐wrapped Co3O4 nanoparticles, as well as the cross‐linked fibrous nitrogen‐doped carbon texture.

Published: April 2019

AbstractLithium‐ion batteries (LIBs) are one of the most significant energy storage devices applied in power supply facilities. However, a huge number of spent LIBs would bring harmful resource waste and environmental hazards. In this study, a benign hydrometallurgical method using phytic acid as precipitant is proposed to recover useful metallic Mn ions from spent LiMn2O4 batteries. Besides Mn‐based cathodes, this recovery process is also applicable for other commercial batteries. More importantly, for the first time, the as‐obtained manganous complex is employed as a nanofiller in a polyethylene oxide matrix to largely improve Li+ conductivity and transference number. As a result, when applied in all‐solid‐state lithium batteries, high capacity and outstanding cyclic stability are achieved with capacity retention of 86.4 % after 60 cycles at 0.1 C. The recovery of spent lithium batteries not only has benefits for the environment and resources, but also shows great potential application in all‐solid‐state lithium batteries, which opens up a costless and efficient circulation pathway for clean and reliable energy storage systems.

AbstractDesiccant driven dehumidification for maintaining the proper humidity levels and atmospheric water capture with minimum energy penalty are important aspects in heat pumps, refrigeration, gas and liquid purifications, gas sensing, and clean water production for improved human health and comfort. Water adsorption by using nanoporous materials has emerged as a viable alternative to energy‐intensive industrial processes, thus understanding the significance of their porosity, high surface areas, vast pore volumes, chemical and structural features relative to the water adsorption is quite important. In this review article, important features of nanoporous materials are presented, including zeolites, porous carbons, as well as crystalline and amorphous porous organic polymers (POPs) to define the interactions between the water molecules and the polar/non‐polar functional groups on the surface of these nanoporous materials. In particular, focus is placed on the recent developments in POPs in the context of water capture as a result of their remarkable stability towards water and wide range of available synthetic routes and building blocks for their synthesis. We also highlighted recent approaches to increase the water sorption capacity of POPs by modifying their structure, morphology, porosity, and chemical functionality while emphasizing their promising future in this emerging area.

BackgroundPrevious studies have demonstrated an association between a diagnosis of cancer and the risk of suicide; however, they failed to account for psychiatric care before a cancer diagnosis, which may confound this relationship. The objective of this study was to assess the effect of a cancer diagnosis on the risk of suicide, accounting for prediagnosis psychiatric care utilization.MethodsAll adult residents of Ontario, Canada who were diagnosed with cancer (1 of prostate, breast, colorectal, melanoma, lung, bladder, endometrial, thyroid, kidney, or oral cancer) between 1997 and 2014 were identified. Noncancer controls were matched 4:1 based on sociodemographics, including a psychiatric utilization gradient (PUG) score (with 0 indicating none; 1, outpatient; 2, emergency department; and 3, hospital admission). A marginal, cause‐specific hazard model was used to assess the effect of cancer on the risk of suicidal death.ResultsAmong 676,470 patients with cancer and 2,152,682 matched noncancer controls, there were 8.2 and 11.4 suicides per 1000 person‐years of follow‐up, respectively. Patients with cancer had an overall higher risk of suicidal death compared with matched patients without cancer (hazard ratio, 1.34; 95% CI, 1.22‐1.48). This effect was pronounced in the first 50 months after cancer diagnosis (hazard ratio, 1.60; 95% CI, 1.42‐1.81); patients with cancer did not demonstrate an increased risk thereafter. Among individuals with a PUG score 0 or 1, those with cancer were significantly more likely to die of suicide compared with controls. There was no difference in suicide risk between patients with cancer and controls for those who had a PUG score of 2 or 3.ConclusionsA cancer diagnosis is associated with increased risk of death from suicide compared with the general population even after accounting for precancer diagnosis psychiatric care utilization. The specific factors underlying the observed associations remain to be elucidated.
