Abstract. The Global Positioning System – Radio Occultation (GPS-RO) observations from FormoSat-3 ∕ COSMIC are used to comprehend the global distribution of equatorial plasma bubbles which are characterized by depletion regions of plasma in the F region of the ionosphere. Plasma bubbles that cause intense scintillation of the radio signals are identified based on the S4 index derived from the 1 Hz raw signal-to-noise ratio measurements between 2007 and 2017. The analyses revealed that bubbles influenced by background plasma density occurred along the geomagnetic equator and had an occurrence peak around the dip equator during high solar activity. The peak shifted between the African and American sectors, depending on different solar conditions. Plasma bubbles usually developed around 19:00 local time (LT), with maximum occurrence around 21:00 LT during solar maximum and ∼22:00 LT during solar minimum. The occurrence of bubbles showed a strong dependence on longitudes, seasons, and solar cycle with the peak occurrence rate in the African sector around the March equinox during high solar activity, which is consistent with previous studies. The GPS-RO technique allows an extended analysis of the altitudinal distribution of global equatorial plasma bubbles obtained from high vertical resolution profiles, thus making it a convenient tool which could be further used with other techniques to provide a comprehensive view of such ionospheric irregularities.

Abstract. Fragility curves (FCs) are key tools for seismic probabilistic safety assessments that are performed at the level of the nuclear power plant (NPP). These statistical methods relate the probabilistic seismic hazard loading at the given site to the required performance of the NPP safety functions. In the present study, we investigate how the tools of non-stationary extreme value analysis can be used to model in a flexible manner the tail behaviour of the engineering demand parameter as a function of the considered intensity measure. We focus the analysis on the dynamic response of an anchored steam line and of a supporting structure under seismic solicitations. The failure criterion is linked to the exceedance of the maximum equivalent stress at a given location of the steam line. A series of three-component ground-motion records (∼300) were applied at the base of the model to perform non-linear time history analyses. The set of numerical results was then used to derive a FC, which relates the failure probability to the variation in peak ground acceleration (PGA). The probabilistic model of the FC is selected via information criteria completed by diagnostics on the residuals, which support the choice of the generalised extreme value (GEV) distribution (instead of the widely used log-normal model). The GEV distribution is here non-stationary, and the relationships of the GEV parameters (location, scale and shape) are established with respect to PGA using smooth non-linear models. The procedure is data-driven, which avoids the introduction of any a priori assumption on the shape or
form of these relationships. To account for the uncertainties in the mechanical and geometrical parameters of the structures (elastic stiffness, damping, pipeline thicknesses, etc.), the FC is further constructed by integrating these uncertain parameters. A penalisation procedure is proposed to set to zero the variables of little influence in the smooth non-linear models. This enables us to outline which of these parametric uncertainties have negligible influence on the failure probability as well as the nature of the influence (linear, non-linear, decreasing, increasing, etc.) with respect to each of the GEV parameters.

Identification of Eigen-Frequencies and Mode-Shapes of Beams with Continuous Distribution of Mass and Elasticity and for Various Conditions at Supports
Authors: K. Makarios Triantafyllos 
Published: May 2020

In the present article, an equivalent three degrees of freedom (DoF) system of two different cases of inverted pendulums is presented for each separated case. The first case of inverted pendulum refers to an amphi-hinge pendulum that possesses distributed mass and stiffness along its height, while the second case of inverted pendulum refers to an inverted pendulum with distributed mass and stiffness along its height. These vertical pendulums have infinity number of degree of freedoms. Based on the free vibration of the above-mentioned pendulums according to partial differential equation, a mathematically equivalent three-degree of freedom system is given for each case, where its equivalent mass matrix is analytically formulated with reference on specific mass locations along the pendulum height. Using the three DoF model, the first three fundamental frequencies of the real pendulum can be identified with very good accuracy. Furthermore, taking account the 3 × 3 mass matrix, it is possible to estimate the possible pendulum damages using a known technique of identification mode-shapes via records of response accelerations. Moreover, the way of instrumentation with a local network by three accelerometers is given via the above-mentioned three degrees of freedom.
DCLK1 and DNA Damage Response

Published: May 2020

Genome integrity is constantly monitored by sophisticated cellular networks, collectively termed as the DNA damage response (DDR). The DDR is a signaling network that includes cell cycle checkpoints and DNA repair and damage tolerance pathways. Failure of the DDR or associated events causes various diseases, including cancer. DDR is primarily mediated by phosphatidylinositol-3-kinase-like protein kinase (PIKKs) family members ataxia-telangiectasia mutated (ATM) and ataxia telangiectasia and Rad3-related protein (ATR). However, one of the many unanswered questions regarding these signal-transduction pathways is: how does the cell turn the DDR signals on? There was no conclusive demonstration of the involvement of a specific sensory kinase in DDR signals until our recent research on the DCLK1 role in regulating ATM after genotoxic injury. Currently, various studies are demonstrating the importance of DCLK1 in DNA damage response. Here, we discuss the novel insights into the role of DCLK1 in DNA damage response.
Schools for Thought

Schools for Thought provides a straightforward, general introduction to cognitive research and illustrates its importance for educational change.
If we want to improve educational opportunities and outcomes for all children, we must start applying what we know about mental functioning—how children think, learn, and remember in our schools. We must apply cognitive science in the classroom. Schools for Thought provides a straightforward, general introduction to cognitive research and illustrates its importance for educational change.
Using classroom examples, Bruer shows how applying cognitive research can dramatically improve students' transitions from lower-level rote skills to advanced proficiency in reading, writing, mathematics, and science. Cognitive research, he points out, is also beginning to suggest how we might better motivate students, design more effective tools for assessing them, and improve the training of teachers. He concludes with a chapter on how effective school reform demands that we expand our understanding of teaching and learning and that we think about education in new ways. Debates and discussions about the reform of American education suffer from a lack of appreciation of the complexity of learning and from a lack of understanding about the knowledge base that is available for the improvement of educational practice. Politicians, business leaders, and even many school superintendents, principals, and teachers think that educational problems can be solved by changing school management structures or by creating a market in educational services. Bruer argues that improvement depends instead on changing student-teacher interactions. It is these changes, guided by cognitive research, that will create more effective classroom environments.

Authors: Yan Shuangqian , Zeng Xuemei , Wang Yu , Liu Bi‐Feng 
Published: May 2020

AbstractBiomimetic mineralization of live organisms shows extraordinary promise in biotechnology. However, their therapeutic applications have been insufficiently explored. Herein, it is demonstrated that metal–organic framework (MOF)‐engineered bacteria are powerful carriers for tumor‐targeted therapeutic delivery. Specifically, Escherichia coli (MG1655) is coated with a zeolitic imidazolate framework‐8 layer coloaded with a photosensitizer and chemical drug through a one‐step in situ method. The as‐prepared bacteria@MOF hybrid preserves its viability and tumor selectivity. It exhibits high therapeutic efficacy both in vitro and in vivo in a combined chemo‐photodynamic manner. To the best of knowledge, this is the first report of engineered bacteria@MOFs for in vivo tumor treatment. This study opens a new horizon for the bioapplications of biomineralized organisms and may provide novel strategies against tumors.

Published: May 2020

AbstractThis work presents a facile method to fabricate composite encapsulation bilayer films with ultrahigh barrier performance for the blue organic light‐emitting diodes (OLEDs). The encapsulation film is composed of the SiNx and Al2O3 layers prepared via incorporation of plasma enhanced chemical vapor deposition (PECVD) and spatial atomic layer deposition (S‐ALD) methods. It is found that the hybrid bilayer films possess excellent barrier performance with water vapor transmission rate (WVTR) of ≈10−6 g m−2 day−1 and a long lag time. No black spots are found when applied to the blue OLEDs for more than 1000 h under the accelerated aging condition. The improved stability of the composite barrier originates from introduction of the nanoscale Al2O3 to SiNx layer, leading to the decrease of the stored strain energy. Besides, the Al2O3 layer could help decouple the pinholes on the SiNx surfaces, which blocks permeation of the moisture to degrade the OLEDs. The interface toughness between the OLED and barrier remains stable, which hinders the delamination of the SiNx layer in the severe environment completely.

AbstractThermodynamic behavior investigations on nanomaterials are of great scientific interest and possess technological implications for advancing nanoscience and nanotechnology. However, nanoscale thermodynamic studies on ceramic semiconductors are faced with great challenges due to their thermostability, and there lacks a percipient understanding of their atomistic thermal behaviors. Here, the atomic‐scale mechanism of the melting and coalescence processes of binary semiconductors, including rutile TiO2(R) and SnSe nanostructures, via real‐time electron beam (e‐beam) irradiation is reported. Under the e‐beam, the inelastic electron‐matter interactions and the low thermal conductivity of the samples cause a local temperature increase. The in situ melting process is recorded via high‐resolution TEM imaging, which exclusively shows a specific planar melting order of the (001), (011), and (100) for TiO2(R). This measurement provides direct evidence that matches the surface energy differences predicted by existing theoretical calculations and experiments. A similar phenomenon is induced and observed on SnSe, which derives a particular melting order of (210), (211), and (002). Furthermore, the in situ melting and coalescence analysis of ultrafine TiO2(R) nanoparticles suggests surface atom transfer and recrystallization as observed. The demonstration of e‐beam directed shape formation and tailoring reveals the possibility for nano/microscale processing of ceramic nanostructures, which are otherwise considered chemically stable and mechanically robust.
Multi‐Scale In Situ Tribological Studies of Surfaces with 3D Textures Fabricated via Two‐Photon Lithography and Replica Molding
Authors: Afshar‐Mohajer Mahyar , Zou Min 
Published: May 2020

AbstractSurface texturing not only decreases friction by reducing the real area of contact but also is crucial for achieving multifunctionality. However, texturing a surface might undermine its deformation resistance due to increased sliding contact pressure. High resolution, 3D control over texture shapes can potentially address this issue. Utilizing a micro/nano‐scale additive manufacturing method based on two‐photon polymerization, textures are fabricated with precise shape, dimension, and position control. This allows for a systematic investigation of the effects of texture three‐dimensionality by comparing 3D textures (truncated cones) with 2.5D textures (cylinders and rods). Moreover, macro‐ and micro‐scale tribological testing and in situ monitoring of the experiments using a digital microscope at macro‐scale and a scanning electron microscope (SEM) at micro‐scale provides unique insights into the multi‐scale tribological properties of the textured surfaces by real‐time monitoring of the interplay between the forces and the sliding surfaces down to a single micro‐scale structure level. Macro‐scale tests show that cones not only have a lower coefficient of friction due to their reduced area of contact but also slide more smoothly and are more durable. Micro‐scale tests shed new light on the relationship between friction and the microstructure deformation by in situ SEM monitoring of texture‐counterface interactions.

AbstractPhotodynamic therapy (PDT) is a promising treatment for cancer, but the hypoxic tumor microenvironment limits its therapeutic effect, especially in these oxygen‐dependent PDT‐II systems. Herein, a nanoporous MOF@POP composite, named UBP, is synthesized by template strategy to effectively integrate BODIPY‐contained porous organic polymers (POP) and MOF within one system. Such UBP possesses well dispersibility and pH‐triggered type I photodynamic performance, which shows a selected toxicity to cancer cells (HeLa cells) but less damage to normal cells (L929 cells).
Thermo‐Phototronic Effect Induced Electricity in Long Semiconducting ZnO Materials for Self‐Powered Light and Temperature Sensors
Authors: Gao Tiantian , Ji Yun , Yang Ya 
Published: May 2020

AbstractSelf‐powered multi‐functional sensors are expected to play an important role in the internet of things technology because they do not need external power and can monitor environmental variations. Previous investigations about sensors have mainly focused on the monitoring of one stimulus, while the simultaneous detection of temperature and light is still a challenge. Here, a two‐parameter sensor with Ohmic contact is reported, which realizes the functions of individually and simultaneously detecting light and temperature via the thermo‐phototronic effect of ZnO ceramic material. The output current signals of the sensor at a light intensity of 0.24 W cm–2 and under a temperature gradient of 9.5 K across the device are 7.14 µA and 45.61 µA, respectively, and the total current is 52.77 µA when the two conditions co‐exist at the same time. This study provides a new research direction into the thermo‐phototronic effect to realize multi‐functional self‐powered sensor systems via oxide semiconducting materials.

AbstractPorous materials are widely studied for water purification and treatment as they can function as efficient adsorbents for harmful chemical wastes with their high specific surface areas. Among various types of porous materials, metal‐organic frameworks (MOFs) have emerged as promising adsorbents for organic pollutants although the general powder form of MOFs largely limits their recyclability in practical applications. Herein, highly crystalline MOF particles are incorporated into agarose (AG) to fabricate highly recyclable MOF aerogels. Along with greatly improved recyclability, these MOF aerogels also achieve eco‐friendliness and cost‐effectiveness because AG is highly abundant in nature and can be easily modified. Typically, MOF aerogels are synthesized by uniformly dispersing MOF particles into the AG solution. The resulting MOF aerogels show significantly improved efficiency for dye adsorption. It is believed that this fabrication method for the preparation of MOF aerogels is highly versatile and it can be extended to other types of MOFs for different applications including environmental remediation, energy storage and conversion, and sensing.

AbstractThis work investigates the potential of glycosylation to actively target nanodrug delivery systems to adult solid tumors overexpressing glucose transporters. The highly hydrophobic fluorescent compound curcumin (CUR) is nanoencapsulated within polymeric micelles of pristine and glucosylated poly(ethylene oxide)‐poly(propylene oxide) block copolymers, and their interaction with breast cancer (BC) cells is investigated in vitro and in vivo. The aqueous solubility of CUR is increased more than 50 000‐fold and spherical nanoparticles display size in the 40 to 500 nm range, as determined by transmission electron microscopy and by dynamic light scattering, respectively. Uptake studies conducted in the BC cell line 4T1 in vitro demonstrate that glucosylation enhances nanoparticle internalization. Finally, the ability of unmodified and glucosylated polymeric micelles to accumulate in female BALB/c mice bearing 4T1‐induced tumors is compared by ex vivo bioimaging with auspicious results.

AbstractCatalyst support with good conductivity and stability is an eternal pursuit in the search for a high‐performance electrocatalyst. Here, an unusual catalyst support, laser‐modified boron nitride with C, O dopants (L‐BN), for the oxygen evolution reaction is reported. L‐BN exhibits unique advantages for electrocatalysis, namely, high corrosion resistance under oxidizing conditions, enhanced electrical conductivity arising from interlayer B–B dipolar interaction, and strong interaction with IrOx catalyst caused by NCN bonds. As an excellent substrate, L‐BN helps to achieve higher activity and stability than its carbon black counterpart.

AbstractTandem structure provides a practical way to realize high efficiency organic photovoltaic cells, it can be used to extend the wavelength coverage for light harvesting. The interconnecting layer (ICL) between subcells plays a critical role in the reproducibility and performance of tandem solar cells, yet the processability of the ICL has been a challenge. In this work the fabrication of highly reproducible and efficient tandem solar cells by employing a commercially available material, PEDOT:PSS HTL Solar (HSolar), as the hole transporting material used for the ICL is reported. Comparing with the conventional PEDOT:PSS Al 4083 (c‐PEDOT), HSolar offers a better wettability on the underlying nonfullerene photoactive layers, resulting in better charge extraction properties of the ICL. When FTAZ:IT‐M and PTB7‐Th:IEICO‐4F are used as the subcells, a power conversion efficiency (PCE) of 14.7% is achieved in the tandem solar cell. To validate the processability of these tandem solar cells, three other research groups have successfully fabricated tandem devices using the same recipe and the highest PCE obtained is 16.1%. With further development of donor polymers and device optimization, the device simulation results show that a PCE > 22% can be realized in tandem cells in the near future.
