Context.—Obtaining diagnostic concordance for squamous intraepithelial lesions in cytology can be challenging.Objective.—To determine diagnostic concordance for biopsy-proven low-grade squamous intraepithelial lesion (LSIL) and high-grade squamous intraepithelial lesion (HSIL) Papanicolaou test slides in the College of American Pathologists PAP Education program.Design.—We analyzed 121 059 responses from 4251 LSIL and HSIL slides for the interval 2004 to 2013 using a nonlinear mixed-model fit for reference diagnosis, preparation type, and participant type. We evaluated interactions between the reference diagnosis and the other 2 factors in addition to a repeated-measures component to adjust for slide-specific performance.Results.—There was a statistically significant difference between misclassification of LSIL (2.4%; 1384 of 57 664) and HSIL (4.4%; 2762 of 63 395). There was no performance difference between pathologists and cytotechnologists for LSIL, but cytotechnologists had a significantly higher HSIL misclassification rate than pathologists (5.5%; 1437 of 27 534 versus 4.0%; 1032 of 25 630; P = .01), and both were more likely to misrepresent HSIL as LSIL (P &lt; .001) than the reverse. ThinPrep LSIL slides were more likely to be misclassified as HSIL (2.4%; 920 of 38 582) than SurePath LSIL slides (1.5%; 198 of 13 196), but conventional slides were the most likely to be misclassified in both categories (4.5%; 266 of 5886 for LSIL, and 6.5%; 573 of 8825 for HSIL).Conclusions.—More participants undercalled HSIL as LSIL (false-negative) than overcalled LSIL as HSIL (false-positive) in the PAP Education program, with conventional slides more likely to be misclassified than ThinPrep or SurePath slides. Pathologists and cytotechnologists classify LSIL equally well, but cytotechnologists are significantly more likely to undercall HSIL as LSIL than are pathologists.

Кинетика слияния однослойных везикул, вызванная добавлением диметил-(ДМСО) и диэтилсульфоксидов (ДЭСО) с мольными долями 0.1 и 0.2, изучена в жидкокристаллической фазе с помощью малоуглового рассеяния нейтронов. Мультислойные везикулы, образованные в результате частичного слияния однослойных везикул 1,2-димиристоил-sn-глицеро-3-фосфадилхолина (ДМФХ) при добавлении ДМСО (ХДМСО = 0.1, 0.2) и ДЭСО (ХДЭСО = 0.2), стабильны в течение длительного времени. Процесс охлаждения-нагревания не влияет на стабильность образованных систем. Присутствие ДМСО и ДЭСО с мольной долей 0.2 приводит к исчезновению риппл-фазы. Добавление ДЭСО к однослойным везикулам ДМФХ в D2O с мольной долей 0.1 не влияет на структуру однослойных везикул в течение 5-15 мин после добавления сульфоксида в жидкокристаллическую фазу. Спустя три часа формируется стабильная система, состоящая из однослойных везикул с липидным бислоем толщиной = 27.3(2) и мультислойных везикул с периодом повторяемости d = 43.6(2) . При охлаждении мультислойные везикулы разрушаются в области основного фазового перехода = 24.8(9)°C для исследуемой системы), и образуются однослойные везикулы.

Проведен синтез гидридных фаз интерметаллических соединений GdNi3 и DyNi3 при комнатной температуре и 273 К и давлении водорода 1-30 бар. Методом рентгеновской дифракции установлен фазовый состав полученных образцов и определены параметры решетки гидридных фаз. При комнатной температуре и давлении ~1 бар синтезируются кристаллические фазы. При температуре 273 К и давлении 30 бар образуются аморфизированные гидриды. Десорбция водорода из аморфизированных гидридов при T = 573 К приводит к формированию хорошо закристаллизованных образцов исходных интерметаллидов. Образование аморфизированных фаз связано с упорядочением атомов водорода в металлической матрице гидрида при низкой температуре.

Published: August 2018

AbstractRecent work that establishes a picture of the driving forces that govern material transformations and degradation in electrochemical environments to enable the ab initio design of electrochemical materials is highlighted. Select prototype systems are used to describe how the interplay between materials properties such as crystal field splitting, band edge energies, surface termination, material length scale, dielectric constant, and isoelectric point, and electrolyte properties such as pH and ion type, impacts electrochemical behavior—i.e., redox potentials, reaction enthalpies, reactivity, and decoupled ionic/electronic processes. Ab initio modeling of charged defects and intercalants within the grand canonical unified electrochemical band‐diagram (UEB) framework is shown to enable the quantitative prediction of electrochemical materials behavior. UEB combines electrochemical theory, charged defect theory, and band diagram descriptions and can be used both for materials discovery and development. First, a pedagogical description of the UEB framework is presented, and then the application of this framework to reveal mechanisms for high rate electronic charge storage in cation incorporated α‐MnO2 and λ‐MnO2, high desalination efficiency of thin‐film NaMn4O8, and the flat charge/discharge profile of FePO4 is reviewed. Finally, new prospects for the application of the UEB framework to electrolyte design, interfacial engineering, and catalysis are suggested.

Published: August 2018

AbstractDielectric capacitors, which store electrical energy in the form of an electrostatic field via dielectric polarization, are used in pulsed power electronics due to their high power density and ultrashort discharge time. In pursuit of developing high‐performance dielectric capacitors, special attention has been given to the improvement of their energy density and storage efficiency, which would make them useful for an even wider variety of applications. Among the different dielectric materials studied so far, including polymers, glasses, and both bulk and film‐based ceramics, dielectric ceramic films, which are of particular interest for miniature power electronics and mobile platforms, have demonstrated the greatest energy storage performances. In this regard, several interesting approaches involving physical, chemical, and microstructural modifications of the dielectric ceramic films are adopted. In addition to a brief discussion of the polymers, glasses, and ceramics used in dielectric capacitors and key parameters related to their energy storage performance, this review article presents a comprehensive overview of the numerous efforts made toward enhancing the energy storage properties of linear dielectric, paraelectric, ferroelectric, relaxor ferroelectric, and anti‐ferroelectric ceramic films for their applications in pulsed power capacitors.

AbstractCapillary‐fed boiling of water from microporous metal surfaces is promising for low thermal resistance vapor chamber heat spreaders for hot spot management. Vapor transport through the void spaces in porous metals enables high heat fluxes at low evaporator superheat. In this work, the critical heat fluxes of capillary‐fed boiling in copper inverse opal (IO) wicks that consist of uniform pores with 3D periodicity is investigated. Template sintering is used to enlarge the “necks”, or hydraulic vias, that bridge adjacent IO pores of diameters from 0.6 to 2.1 µm. The enhanced neck size increases the hydraulic permeability for vapor extraction by an order of magnitude, and subsequently the CHF from 100 to 1100 W cm−2. Modeling of the boiling limit accounts for the vapor pressure drop through an IO wick using Darcy's law at a given bubble departure rate. This work links the effect of wick structure design on the boiling crises phenomenon in microporous surfaces and demonstrates material capabilities for ultrathin and low superheat thermal management solutions for high‐power‐density electronic devices.

AbstractElectromagnetic wave (EM) absorption materials with broader effective absorption bandwidth (EAB), lightweight, and thinness characteristics are highly desirable in areas of wearable device and portable electronics. However, there are still many obstacles to simultaneously satisfy the above critical requirements required by new high‐performance EM absorption materials. Herein, for the first time, Ti3C2TX MXenes are selected as the dielectric mediator to prepare reduced graphene oxide (RGO)/Ti3C2TX hybrids foam with hollow core–shell architectures and controllable complex permittivity via self‐assembly and sacrificial template processes, under the guidance of theoretical calculations. RGO is grafted flatly on the outer surface of the Ti3C2TX spheres‐core, forming a unique heterostructure. The RGO/Ti3C2TX foam possesses excellent EM absorption performance superior to all reported foam‐based counterparts, the EAB covers the whole X‐band at 3.2 mm while the density is merely 0.0033 g cm−3, and its specific EM absorption performance (SMAP = RL (dB)/Thickness (cm)/Density (g cm−3)) value exceeds 14 299.2 dB cm−2 g−1, verifying the above theoretical results. This study is expected to guide future exploration on designing high‐performance EM absorption materials, and the RGO/Ti3C2TX foam can be promising candidates in energy storage, sensors, and wearable electronics fields.

AbstractAlthough metallic ruthenium (Ru) is a potential electrocatalyst for the hydrogen evolution reaction (HER) to replace platinum (Pt) at a cost of only ≈4% of Pt, the persistent dissolution of Ru under operation conditions remains a challenge. Here, it is reported that agglomerates of large ruthenium phosphide (RuP) particles (L‐RP, ≈32 nm) show outstanding HER performance in pH‐universal electrolytes, which particularly demonstrates a surprisingly higher intrinsic activity and durability than small nanoparticles of RuP (S‐RP, ≈3 nm) or metallic Ru on carbon supports. This is especially true in basic media, achieving electrocatalytic activity comparable to or even outperforming that of Pt/C, as reflected by lower overpotential at 10 mA cm−2, smaller Tafel slope, larger exchange current density, and higher turnover frequency while maintaining 200 h stable operation. Calculations suggest that ΔGH* of RuP is much closer to zero than that of metallic Ru, and phosphorous doping is proven to enhance the rate of proton transfer in HER, contributing in part to the improved activity of RuP. The better performance of L‐RP than that of S‐RP is ascribed largely to the stabilization of the P species due to the lowered surface energy of large particles. Furthermore, the relatively low‐cost materials and facile synthesis make L‐RP/C a highly attractive next‐generation HER electrocatalyst.

AbstractA surge in interest of oxide‐based materials is testimony for their potential utility in a wide array of device applications and offers a fascinating landscape for tuning the functional properties through a variety of physical and chemical parameters. In particular, selective electronic/defect doping has been demonstrated to be vital in tailoring novel functionalities, not existing in the bulk host oxides. Here, an extraordinary interstitial doping effect is demonstrated centered around a light element, boron (B). The host matrix is a novel composite system, made from discrete bulk LaAlO3:LaBO3 compounds. The findings show a spontaneous ordering of the interstitial B cations within the host LaAlO3 lattices, and subsequent spin‐polarized charge injection into the neighboring cations. This leads to a series of remarkable cation‐dominated electrical switching and high‐temperature ferromagnetism. Hence, the induced interstitial doping serves to transform a nonmagnetic insulating bulk oxide into a ferromagnetic ionic–electronic conductor. This unique interstitial B doping effect upon its control is proposed to be as a general route for extracting/modifying multifunctional properties in bulk oxides utilized in energy and spin‐based applications.

AbstractExploring highly efficient and low‐cost electrocatalysts for electrochemical water splitting is of importance for the conversion of intermediate energy. Herein, the synthesis of dual‐cation (Fe, Co)‐incorporated NiSe2 nanosheets (Fe, Co‐NiSe2) and systematical investigation of their electrocatalytic performance for water splitting as a function of the composition are reported. The dual‐cation incorporation can distort the lattice and induce stronger electronic interaction, leading to increased active site exposure and optimized adsorption energy of reaction intermediates compared to single‐cation‐doped or pure NiSe2. As a result, the obtained Fe0.09Co0.13‐NiSe2 porous nanosheet electrode shows an optimized catalytic activity with a low overpotential of 251 mV for oxygen evolution reaction and 92 mV for hydrogen evolution reaction (both at 10 mA cm−2 in 1 m KOH). When used as bifunctional electrodes for overall water splitting, the current density of 10 mA cm−2 is achieved at a low cell voltage of 1.52 V. This work highlights the importance of dual‐cation doping in enhancing the electrocatalyst performance of transition metal dichalcogenides.

AbstractComplex oxide interfaces have mesmerized the scientific community in the last decade due to the possibility of creating tunable novel multifunctionalities, which are possible owing to the strong interaction among charge, spin, orbital, and structural degrees of freedom. Artificial interfacial modifications, which include defects, formal polarization, structural symmetry breaking, and interlayer interaction, have led to novel properties in various complex oxide heterostructures. These emergent phenomena not only serve as a platform for investigating strong electronic correlations in low‐dimensional systems but also provide potentials for exploring next‐generation electronic devices with high functionality. Herein, some recently developed strategies in engineering functional oxide interfaces and their emergent properties are reviewed.

Published: August 2018

AbstractMechanochromic polymeric systems are intensively investigated for real‐time stress detection applications. However, an effective stress‐sensing material must respond to low deformation with a detectable color change that should be quickly reversible upon force unloading. In this work, mechanochromic nanofibers made by electrospinning are used to produce mechanochromic nanofiber/poly(dimethylsiloxane) (PDMS) composites with isotropic and anisoptropic response. Due to chain alignment of spiropyran copolymer chains within the nanofibers, only very small strains are required to yield a mechanochromic response. Composites with aligned and isotropic nanofibers show anisotropic and isotropic mechanochromic behavior, respectively. Due to the special substitution pattern of spiropyran in the copolymer, the mechanochromic response of these nanofiber/PDMS composites shows fast reversibility upon force unloading. The outstanding benefit of using highly sensitive mechanochromic nanofibers as filler in composite materials allows the detection of directional stress and strain, and it is a step forward in the development of smart, mechanically responsive materials.

AbstractSurface/interface design is one of the most significant and promising motivations to develop high‐performance catalysts for electrolytic water splitting. Here, the nature of cytomembrane having the most effective and functional surface structure is mimicked to fabricate a new configuration of Ni–N–O porous interface nanoparticles (NiNO INPs) with strongly interacting nanointerface between the Ni3N and NiO domains, for enhancing the electrocatalytic oxygen evolution reaction (OER) performance. The combination of transmission electron microscopy and electrochemical investigations, tracking the correlation between microstructure evolution and catalytic activity, demonstrate the strongly coupled nanointerface for an approximately sixfold improvement of electrolytic efficiency. Density functional theory simulates the electrocatalytic process with a maximum of 85% reduction of the energy barrier. Further investigations find that the real active site for the OER in the NiNO INPs is the strongly coupled Ni–N–O nanointerface, not the derived amorphous hydroxide, during the OER process. The determination of the correlation of constructed nanointerface with catalytic properties suggests a significant strategy toward the rational design of catalysts for efficient water electrocatalysis.

AbstractA variety of dopant‐free hole‐transporting materials (HTMs) is effectively applied in perovskite solar cells (PSCs); however, HTMs with the additional function of HTM/perovskite interfacial optimization that is crucial to their photovoltaic performance are really limited. In this work, the design of an HTM bearing an intensive exposure of its functional aromatic rings to perovskite layer via side‐chain engineering is attempted. With an edge‐on orientation and a short distance to perovskite, this HTM was expected to display an excellent ability to extract holes from and passivate defects in the perovskite layer. To demonstrate this strategy, an alternating copolymer was constructed with a 2,5‐di‐2‐ethylhexyloxy‐1,4‐phenylene unit and a bithiophene unit, and the PSC based on this polymer showed an ultrahigh short‐circuit current density of 25.50 mA cm−2, which was the highest so far presented by dopant‐free organic HTMs. A comparable power conversion efficiency of 19.68% (certified: 19.5%) to that of a control 2,2′,7,7′‐tetrakis(N,N‐di‐p‐methoxyphenylamine)‐9,9′‐spirobifluorene (spiro‐OMeTAD) device (19.81%) was thus obtained, which is the highest value ever reported for mesoporous PSCs based on dopant‐free polymeric HTMs.
