first_imgA brilliant innovation by graduate students of the University of California, Irvine. The CodeGenie will cut down on hours of painstaking search and filter. It is an Eclipse plugin that searches Open Source code and its results are amazing. The Donald Bren School of Information and Computer Science at the University of California, Irvine has added another prestigious award for innovation. Graduate students Sushil Bajracharya, Joel Ossher combined with the efforts of visiting Brazilian student Otavio Lemos have captured the OOPSLA Award in Montreal, Canada. The innovation CodeGenie is an Eclipse plugin that uses test cases as the interface for searching open source code on the Internet.Eclipse is an open universal platform for tool integration, IDE and an open source community. It is royalty free and offers developers choice in multi-languages, multi-platform, multi-vendor supported environment that can be supported by multi-vendors. Eclipse has been noticed by and the subject of interest for developers in Windows, Linux, Solaris, HP-UX, AIX and Mac OS. It is an invaluable source for academic research and design.The abstract of CodeGenie explains that the tool allows developers to test cases first for a desired feature. This is comparable to a Test-driven development. The distinctive feature of CodeGenie is that instead of implementing the feature from scratch, it automatically searches for an existing implementation based on information available for the test. CodeGenie automatically checks the suitability of candidate results and compares the local context. Then the result is automatically woven into the developer’s project and tested again using the original test. This allows the developer to reuse the most suitable results. Following this set of functions the developer is at liberty to unweave the reused code at will during the course of the project. CodeGenie relies on Sourcerer, an Internet-scale source code infrastructure for code searching and wrapping facilities. Sourcerer was also developed by the UCI team.The purpose of the innovation is to free up developers from the laborious task of formulating code queries, filtering the results, and weaving them into the developers project. Open Source code is vast and while it promises almost limitless possibilities for developers the task of getting to suitable results has been daunting and painstakingly slow. CodeGenie plugin has cut out some of the busy work.The OOPSLA Award for the graduate students achievement in developing CodeGenie in Professor Crista Lopes’ lab entitles them to compete in the finals of the ACM Student Research Competition.

first_imgTo demonstrate structural transformation of bidimensional ZnSb polymorphs during 2-D-LiZnSb formation, the scientists conducted synchrotron XRD – during the electrochemical reaction. They observed peaks corresponding to Li alloying of 3-D-ZnSb at pure 2-D-LiZnSb formation, followed by the final product of 2-D-ZnSb. During the electrochemical reaction, the Li atoms selectively penetrated into 3-D-ZnSb to break the Zn-Sb and Sb-Sb bonds. At the level of electron transfer, the hybridized bonding state changed from sp3 in 3-D-ZnSb to sp2 in 2-D-LiZnSb to form the puckered honeycomb lattice. The outcome of Li alloying based 2-D-LiZnSb transformation yielded the 2-D-ZnSb product, which did not return to its 3-D form. Song et al. showed that once formed, the layered 2-D-ZnSb was a stable material with a honeycomb architecture, validating the stable bidimensional polymorphic transition. The scientists anticipate applications of the new material in sustainable alkali ion batteries. In this way, Junseong Song and co-workers performed rigorous experimental and theoretical studies to demonstrate the creation of 2-D layered Zintl phases by manipulating the structural dimensionality. The new method is a first to establish the bidimensional polymorphic family in Zintl phases at ambient pressure, to allow new phase transformations as a general route of synthesis. This work provides a rational design strategy to explore new 2-D layered materials and unlock further properties of interest within materials, such as 2-D magnetism, ferroelectricity, thermoelectricity and topological states for further applications. The discovery of new families of two-dimensional (2-D) layered materials beyond graphene has always attracted great attention, but it remains challenging to artificially recreate the honeycomb atomic lattice structure with multi-components such as hexagonal boron nitride in the lab. In a new study now published on Science Advances, Junseong Song and colleagues at the departments of Energy Science, Nanostructure Physics, Environmental Science and Materials Science in the Republic of Korea developed an unprecedented structure of the Zintl phase. In new materials discovery, transformation of a crystal structure is a widely recognized key factor. Where the temperature-pressure and electrostatic-doping induced structural phase transitions are core to explore a new crystal structure or to switch 2-D materials properties. For instance, most transition metal dichalcogenides exhibit polymorphic phase transition to access inherently diverse properties including superconducting and topological states. The transition has led to promising applications including electronic homojunction, photonic memory devices and catalytic energy materials. Crystal structure of 2D layered ZnSb. (A and B) Atomic resolution STEM-HAADF (high-angle annular dark-field) images of 2D-LiZnSb along the [110] (A) and [001] (B) zone axes, respectively. (C) Atomic resolution STEM-EDS elemental mapping for 2D-LiZnSb along the [110] (top) and [001] (bottom) zone axes.

The atomic distances of 2D-ZnSb are compared with those of 3D-ZnSb and 2D-LiZnSb. From the observation at [211] zone axis of 2D-ZnSb, the honeycomb lattice is slightly tilted. For the detection of lithium, the STEM–EELS (electron energy-loss spectroscopy) technique was used, showing the clear existence and absence of lithium in 2D-LiZnSb and 2D-ZnSb. (G) Cohesive energy (ΔEcoh) calculation of predictable 2D-ZnSb structures.

Credit: Science Advances, doi: 10.1126/sciadv.aax0390 For example, they synthesized the polycrystalline and single crystalline 2-D-LiZnSb intermediate substrate by first alloying Li into polycrystalline 3-D-ZnSb, followed by Li ion etching to form a 2-D-ZnSb crystal. The scientists easily cleaned the Li-etched 2-D-ZnSb crystals using adhesive tape exfoliation as mechanical cleaving to exhibit a typical flat surface as reported for 2-D materials.To understand the effect of the manufacturing process, they examined the role of Li alloying and etching on structural transformations using X-ray photoelectron spectroscopy (XPS) measurements to reveal the difference between the 2-D and 3-D crystals. To further validate their findings, Song et al. used X-ray diffraction spectroscopy (XRD) patterns, transmission electron microscopy (TEM) observations and scanning tunneling electron microscopy (STEM) combined with energy-dispersive spectroscopy (EDS) elemental mapping to confirm the atomic structure of 2-D-ZnSb.Based on the results, the scientists interpreted the stretchable interlayer distances between both Zn-Zn and Sb-Sb atoms as weak interlayer bonds and verified that the 2-D-ZnSb could be exfoliated as a layered material. The newly evolved layered structure of 2-D-ZnSb in the present work, completed the first discovery of bidimensional polymorphism in Zintl phases at ambient pressure.

Previous studies on polymorphic transitions between 3-D and 2-D structures in Zintl phases were only observed under high pressure. The present results on bidimensional polymorphism between 3-D-ZnSb and 2-D-ZnSb emphasized the potential and broad availability of such an electron transfer to transform the crystal structure. Song et al. next investigated electrical transport properties of bidimensional ZnSb polymorphs and 2-D-LiZnSb crystals alongside first principles calculations of their electronic energy band structure. In contrast to the semiconducting nature of 3-D-ZnSb, both 2-D-LiZnSb and 2-D-ZnSb showed metallic conduction behavior. When they decreased the temperature, the electrical mobilities of both 2-D-LiZnSb and 2-D-ZnSb increased to a value higher than that of 3-D-ZnSb. The scientists credited the observed enlarged bandwidths for 2-D-ZnSb to the enhanced sp2 nature of honeycomb-structured layers with weakened interlayer interactions that formed the semi-metal. They used theoretical calculations to confirm that 2-D-ZnSb could be mechanically exfoliated into the bilayer to exist in an energetically stable form as a 2-D material, while the monolayer of 2-D-ZnSb was energetically unfavorable. © 2019 Science X Network These polymorphic transitions only occurred between different layered structures in the same two dimensions and remain to be realized between different dimensions of a crystal structure at ambient pressure. To reach ultimate crystal engineering and alter the structural dimension of multicomponent compounds is a promising next frontier in materials science beyond the allotropes of carbon. In the present work, Song et al. established bidimensional polymorphism via the discovery of 2-D layered structures in Zintl phases containing a large number of chemical compositions. Due to the sp2 hybrid orbital bonding of honeycomb-structured 2-D atomic crystals such as graphene and hexagonal boron nitride, the scientists expected the 3-D structured Zintl phases (with sp3 hybrid orbital bonding) to transform to sp2 honeycomb structured 2-D layered materials, as well, via electron transfer. As a proof-of-concept, Song et al. selected a 3-D orthorhombic ZnSb (3-D-ZnSb) Zintl phase and created the unprecedented, 2-D layered structure of ZnSb (2-D-ZnSb).In the new method, Song et al. first synthesized layered AZnSb (2-D-AZnSb) ternary compounds; where A referred to an alkali metal such as Na, Li and K. The materials contained a layered structure of ZnSb by transforming 3-D-ZnSb via A alloying, although the phases could be independently synthesized. Song et al. performed selective etching of A ions to create the 2-D-ZnSb in two different processes, including (1) chemical reaction in deionized water-incorporated solutions, and (2) electrochemical ion etching reaction in alkali-based electrolyte. Electronic properties of 2D layered ZnSb. (A to C) Temperature dependence of electrical resistivity (A), Hall mobility (B), and carrier concentration (C) for 3D-ZnSb, 2D-LiZnSb, and 2D-ZnSb. The bidimensional polymorphs of 3D-ZnSb and 2D-ZnSb show the metal-insulator transition. (D to F) Electronic band structures of 3D-ZnSb (D), 2D-LiZnSb (E), and 2D-ZnSb (F). The band structures of 3D-ZnSb (D) and 2D-LiZnSb (E) indicate that both are semiconductors with a well-defined indirect bandgap of 0.05 and 0.29 eV, respectively. A low electrical resistivity and a high carrier concentration of 2D-LiZnSb indicate a heavily doped semiconducting behavior. Credit: Science Advances, doi: 10.1126/sciadv.aax0390 They constructed the material by staking sp2-hybridized honeycomb ZnSb layers and via the dimensional manipulation of a crystal structure from the sp3-hybridized 3-D-ZnSb state. The materials scientists combined structural analysis with theoretical calculations to form a stable and robust layered structure of 2-D-ZnSb. This phenomenon of bi-dimensional polymorphism was not previously observed at ambient pressure in Zintl families. Therefore, the new work provides a rational design strategy to search and create new 2-D layered materials in various compounds. The new results will allow the unlimited expansion of 2-D libraries and their corresponding physical properties. The advent of Dirac physics of graphene triggered an explosive interest in research on two-dimensional (2-D) materials with varied applications in electronics, magnetics, energy and chemistry to quantum physics. At present, 2-D research is primarily focused on a few 2-D materials containing a single or several atomic layers exfoliated from their mother compounds, in contrast to 2-D atomic crystals such as silicone. This can restrict the method of 2-D materials development to two approaches of exfoliation and chemical vapor deposition. It is therefore highly desirable to expand on 2-D materials research to artificially create a new 2-D material with a new synthetic approach and form a variety of material groups. Creation of 2D layered ZnSb. (A) Schematic illustration of the dimensional manipulation of a crystal structure from 3D-ZnSb to 2D-ZnSb via Li alloying and etching processes.

However, the Eexf of 2D-ZnSb is lower than that of antimonene, which can be exfoliated or grown into monolayer indicating that free-standing monolayer or few layers of 2D-ZnSb can be possible as conventional 2D vdW layered materials.

first_img“How Many Psychologists Does It Take … to Explain a Joke?” Many, it turns out. As psychologist Christian Jarrett noted in a 2013 article featuring that riddle as its title, scientists still struggle to explain exactly what makes people laugh. Indeed, the concept of humor is itself elusive. Although everyone understands intuitively what humor is, and dictionaries may define it simply as “the quality of being amusing,” it is difficult to define in a way that encompasses all its aspects. It may evoke the merest smile or explosive laughter; it can be conveyed by words, images or actions and through photos, films, skits or plays; and it can take a wide range of forms, from innocent jokes to biting sarcasm and from physical gags and slapstick to a cerebral double entendre. Even so, progress has been made. And some of the research has come out of the lab to investigate humor in its natural habitat: everyday life.

first_imgKolkata: Poignant pieces of verse kept the audience in a thrall as Kolkata organised the country’s first ‘Transgender Poets’ Meet’ here. Eight transgender poets and writers from West Bengal participated in Tuesday’s event, organised by Sahitya Akademi, the country’s national academy of letters under the Union Culture Ministry. “Ekti Patar Mrityu” (Death of a leaf) by Prosphutita Sugandha, “Bichched Ebong” (Separation) by Debdatta Biswas, “Chakravyuh” by Aruna Nath and “Shottikarer Naari” (Real Woman) by Debajyoti Bhattacharya were some of the poems heard on the occasion. Also Read – Rain batters Kolkata, cripples normal life Rani Majumder and Shankari Mondal (Naskar) completed the list of the invited poets, all of whom have accomplished academic qualifications. As a proof of the tremendous enthusiasm the meet had generated in the marginalised community, two transgender persons Anurag Maitrayee and Tista Das, though not invited, shared their poetic creativity on stage after successfully persuading the organisers to give them a chance. Shankari Mondal (Naskar) was earlier a part of that fragment of the transgender community who sing and dance for their living. But now she is a poet and actress. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killed “I have worked in Kaushik Ganguly’s film ‘Nagarkirtan’. It has won four National awards,” said Mondal, who recited her poem ‘Amar Anubhuti'(My Feelings).” Manabi Bandopadhyay, country’s first transgender principal, chaired the event by introducing the participants and also reading few lines of her own poetry. “I wish more and more third gender people come up with their poetry and creations. I am trying my best to organise more such events,” said Bandopadhyay. Eminent poet Subodh Sarkar, the convener of the Akademi’s Bengali advisory board, said: “This is a historic moment and it is our duty to see how literature is taking its own course and creating new assets from everyday life. According to him, the society does not accept new things easily, it takes time. Still, people like Manabi are gradually coming up and gaining acceptance into the mainstream. “However, the word mainstream is very vague and there is a huge debate surrounding the term. We suggested these poets, to speak openly, unabashedly without any inhibition as literary creativity cannot be curbed by any law,” said the Sahitya Akademi awardee. Talking about how Dalit literature has created a niche for itself, Sarkar said: “West Bengal did not see much of it but big names have come up from Maharashtra, Karnataka, Kerala, Tamil Nadu, Odisha and Assam. “Similarly, transgender poetry will find its own course. It is best for the people of the community to talk about themselves through literature as it will have real depth.” A Sahitya Akademi official expressed satisfaction over the response to the event. “This year when the Bengali Advisory Board decided to come up with the unique event, we had no idea that this was India’s first Transgender Poets’ Meet. I am excited to see the audience who appreciated our effort,” said Mihir Sahu, officer-in-charge of the eastern region of Sahitya Akademi. “Our sole purpose is to see how transgender people can share their plight through literature and what role literature plays in helping them to express themselves,” Sahu added.last_img read more
