AbstractMethods for forming high quality re-crystallizing polysilicon films are being actively studied due to their ability to provide significant improvement to polysilicon Thin-Film-Transistors (TFT). Recently, a simple Metal-Induced-Lateral-Crystallization (MILC) method with nickel, together with high temperature annealing, can result in single crystal like polysilicon film [1]. TFTs fabricated on this so-called Large-grain Silicon-On-Insulator (LPSOI) can achieve SOI MOSFET performance especially for making small dimension devices. This paper reports that the polysilicon grain quality can be further enhanced by crystallizing the polysilicon film into the shape of long-wire.The crystallization procedure started with a regular Nickel-Induced-Lateral-Crystallization (NILC) process at 560 °C as described in [1]. The film was then etched into narrow wires, which were parallel to the direction of nickel propagation. The NILC second anneal at 900 °C was then performed on these silicon wire. Through surface energy anisotropy stimulated grain expansion in the NILC high-temperature second annealing, enhanced grain quality beyond that on planar polysilicon film.Transistor fabricated on these wire is similar to gate-all-around structure as that of FinFET [2]. Much better scalability to the deep submicron region was observed for these wire transistors than regular planar TFTs formed on the same NILC film. Experimental results showed that a wide transistor formed by the parallel combination of the quantum wire transistors much higher current drive than a TFT on the same NILC film with equivalent width.

Cooking And Eating Quality

Grain quality is one of the key targets to be improved for rice breeders and covers cooking, eating, nutritional, appearance, milling, and sensory properties. Cooking and eating quality are mostly of concern to consumers and mainly determined by starch structure and composition. Although many starch synthesis enzymes have been identified and starch synthesis system has been established for a long time, novel functions of some starch synthesis genes have continually been found, and many important regulatory factors for seed development and grain quality control have recently been identified. Here, we summarize the progress in this field as comprehensively as possible and hopefully reveal some underlying molecular mechanisms controlling eating quality in rice. The regulatory network of amylose content (AC) determination is emphasized, as AC is the most important index for rice eating quality (REQ). Moreover, the regulatory mechanism of REQ, especially AC influenced by high temperature which is concerned as a most harmful environmental factor during grain filling is highlighted in this review.

With the intensification of global warming, rice production is facing new challenges. Field evidence indicates that elevated temperature during rice grain-filling leads to the further deterioration of grain quality. In order to clarify the potential regulatory mechanism of elevated temperature on the formation of rice quality, the DIA mass spectrometry method under the background of field warming was conducted to investigate the regulatory effects of high temperature on grain development and material accumulation pathways. The results showed that a total of 840 differentially expressed proteins were identified during the grain-filling process under elevated temperature. These differentially expressed proteins participated in carbon metabolism, amino acid biosynthesis, signal transduction, protein synthesis, and alternately affected the material accumulation of rice grains. The significant up-regulation of PPROL 14E, PSB28, granule-bound starch synthase I, and the significant down-regulation of 26.7 kDa heat shock protein would lead to the component difference in grain starch and storage proteins, and that could be responsible for the degradation of rice quality under elevated temperature. Results suggested that proteins specifically expressed under elevated temperature could be the key candidates for elucidating the potential regulatory mechanism of warming on rice development and quality formation. In-depth study on the metabolism of storage compounds would be contributed in further proposing high-quality cultivation control measures suitable for climate warming.
