Transfer printing of high mobility inorganic nanostructures,using an elastomeric transfer stamp,is a potential route for highperformance printed *** this method to transfer nanostructures with high yield,uniformity and excellent registration over large area remain a ***,we present the‘direct roll transfer’as a single-step process,i.e.,without using any elastomeric stamp,to print nanoribbons(NRs)on different substrates with excellent registration(retaining spacing,orientation,etc.)and transfer yield(∼95%).The silicon NR based field-effect transistors printed using direct roll transfer consistently show high performance i.e.,high on-state current(Ion)>1 mA,high mobility(μ_(eff))>600 cm^(2)/Vs,high on/off ratio(I_(on)/_(off))of around 10^(6),and low hysteresis(<0.4 V).The developed versatile and transformative method can also print nanostructures based on other materials such as GaAs and thus could pave the way for direct printing of high-performance electronics on large-area flexible substrates.

Novel CMS lines in pigeonpea[Cajanus cajan(L.)Millspaugh]derived from cytoplasmic substitutions,and their effective restoration and deployment in hybrid breeding

The Crop Journal 2017年第1期5卷 89-94页

作者： abhishek Bohra Rintu Jha Indra Prakash singh Gaurav Pandey Shalini Pareek Partha Sarathi Basu Sushil Kumar Chaturvedi Narendra Pratap singh ICAR Indian Institute of Pulses Research(IIPR)Kanpur 208024India

The availability of stable cytoplasmic male sterile(CMS or A) lines coupled with a robust restoration system(R lines) is an essential prerequisite for efficient hybrid ***-enabled hybrid technology holds immense potential to enhance the long-stagnant productivity of pigeonpea. In the present investigation, cytoplasmic substitutions were made in the nuclear backgrounds of early-maturing pigeonpea varieties or lines. Three new CMS lines(ICPL 88039 A, Pusa 992 A, and DPP 3-2A) resulted from genetic crosses involving cytoplasmic donors from A2(GT 288A) and A4(ICPA 2089) categories. In addition to visual inspection of anthers, pollen-staining techniques and scanning electron microscopy(SEM)analysis were used to confirm pollen sterility. Further, given the relevance of the plant mitochondrial genome to CMS manifestation, 25 mitochondrion-specific DNA markers were assayed on these newly developed A lines and isogenic maintainer(B) lines. DNA polymorphism between Pusa 992 A and Pusa 992 B as revealed by the nad7a_del marker confirmed the successful combination of sterilizing cytoplasm(A4) and nonrestoring nuclear background(Pusa 992). Such cytoplasm-specific DNA markers are required for A2-CMS as well. Further, to assess restoration ability, potential restorers were crossed with these CMS lines, and as a consequence, promising A × R combinations exhibiting 100%pollen fertility could be identified. In parallel, we also analyzed the inheritance patterns underlying fertility restoration using ICPL 88039A-derived F2 and BC1F1populations,and established a monogenic dominant model to explain the phenomenon of A2-CMS restoration. In summary, we report the successful development of new CMS lines and describe their effective deployment in hybrid breeding of pigeonpea.

Patterning Nanoroads and Quantum Dots on Fluorinated Graphene

引用

Nano Research 2011年第1期4卷 143-152页

作者： Morgana A. Ribas abhishek K. singh Pavel B. Sorokin Boris I. Yakobson Department of Mechanical Engineering and Materials Science and Department of Chemistry Rice University Houston Texas 77005 USA Materials Research Centre Indian Institlzte of Science Bangalore 560012 India

Using ab initio methods we have investigated the fluorination of graphene and find that different stoichiometric phases can be formed without a nucleation barrier, with the complete ＂2D-Teflon＂ CF phase being thermody- namically most stable. The fluorinated graphene is an insulator and turns out to be a perfect matrix-host for patterning nanoroads and quantum dots of pristine graphene. The electronic and magnetic properties of the nanoroads can be tuned by varying the edge orientation and width. The energy gaps between the highest occupied and lowest unoccupied molecular orbitals （HOMO-LUMO） of quantum dots are size-dependent and show a confinement typical of Dirac fermions. Furthermore, we study the effect of different basic coverage of F on graphene （with stoichiometries CF and C4F） on the band gaps, and show the suitability of these materials to host quantum dots of graphene with unique electronic properties.
