trehalose(tre)is a non-reducing disaccharide found in many species,including bacteria,fungi,invertebrates,yeast,and even plants,where it acts as an osmoprotectant,energy source,or protein/membrane *** relatively small amounts in plants,tre concentrations increase following exposure to abiotic ***-6-phosphate,a precursor of tre,has regulatory functions in sugar metabolism,crop production,and stress *** the various abiotic stresses,temperature extremes(heat or cold stress)are anticipated to impact crop production worldwide due to ongoing climate *** small amounts of tre can mitigate negative physiological,metabolic,and molecular responses triggered by temperature *** also interacts with other sugars,osmoprotectants,amino acids,and phytohormones to regulate metabolic reprogramming that underpins temperature stress *** plants expressing tre-synthesis genes accumulate tre and show improved stress ***-wide studies of tre-encoding genes suggest roles in plant growth,development,and stress *** review discusses the functions of tre in mitigating temperature stress—highlighting genetic engineering approaches to modify tre metabolism,crosstalk,and interactions with other molecules—and in-silico approaches for identifying novel tre-encoding genes in diverse plant *** consider how this knowledge can be used to develop temperature-resilient crops essential for sustainable agriculture.

Cultivated peanut (Arachis hypogaea) is an allotetraploid crop planted in Asia, Africa, and America for edible oil and protein. to explore the origins and consequences of tetraploidy, we sequenced the allotetraploid A. hypogaea genome and compared it with the related diploid Arachis duranensis and Arachis ipaensis genomes. We annotated 39 888 A-subgenome genes and 41 526 b-subgenome genes in allotetraploid peanut. the A. hypogaea subgenomes have evolved asymmetrically, with the b subgenome resembling the ancestral state and the A subgenome undergoing more gene disruption, loss, conversion, and transposable element proliferation, and having reduced gene expression during seed development despite lacking genome-wide expression dominance. Genomic and transcriptomic analyses identified more than 2 500 oil metabolism-related genes and revealed that most of them show altered expression early in seed development while their expression ceases during desiccation, presenting a comprehensive map of peanut lipid biosynthesis. the availability of these genomic resources will facilitate a better understanding of the complex genome architecture, agronomically and economically important genes, and genetic improvement of peanut.

We describe the design and x-ray emission properties(temporal,spatial,and spectral)of Dry Pinch I,a portable X-pinch driver developed at Imperial College *** Pinch I is a direct capacitor discharge device,30033003700 mm3 in size and∼50 kg in mass,that can be used as an external driver for x-ray diagnostics in high-energy-density physics *** key findings,the device is shown to reliably produce 1.1±0.3 ns long x-ray bursts that couple∼50 mJ of energy into photon energies from 1 to 10 *** average shot-to-shot jitter of these bursts is found to be 10±4.6 ns using a combination of x-ray and current *** spatial extent of the x-ray hot spot from which the radiation emanates agrees with previously published results for X-pinches-suggesting a spot size of 10±6μm in the soft energy region(1–10 keV)and 190±100μm in the hard energy region(>10 keV).these characteristics mean that Dry Pinch I is ideally suited for use as a probe in experiments driven in the laboratory or at external facilities when more conventional sources of probing radiation are not *** the same time,this is also the first detailed investigation of an X-pinch operating reliably at current rise rates of less than 1 ka/ns.

Additive manufacturing of Sm-Fe-N magnets

引用

Journal of Rare Earths 2019年第10期37卷 1078-1082页

作者： J.A.b.Engerroff A.b.baldissera m.D.magalhaes P.h.Lamarao P.A.P.Wendhausen C.h.Ahrens J.m.mascheroni Department of mechanical Engineering Federal University of Santa CatarinaFlorianopolisBrazil Alkimattecnologia Sao JoseBrazil

Isotropic Sm-Fe-N bonded magnets were obtained by additive manufacturing(Am). the technique used was the so-called powder bed fusion(PbF) and the feedstock was composed of a polymeric binder(PA-12) and Sm-Fe-N flake particles(Nitroquench-P). the Am set-up equipment uses a computer-controlled CO2 laser beam to melt the binder and constructs magnets layer-by-layer. In order to develop this study, a cylinder with 10 mm of both height and diameter was selected as the shape of samples. Specimens were analyzed by scanning electron microscopy(SEm) and X-ray diffraction(XRD). magnetic properties were measured in a hysteresis graph. XRD results indicate that there is no degradation of the main magnetic phase(SmFe7 Nx). In the Am component, porous regions were identified on SEm micrographs, as well as magnetic particles and polymeric binder. Remanence values(br) as great as 0.3 t are achieved, while intrinsic coercivities remain in the range from 616 up to 642 ka/m. An additional isostatic compression of the parts results in greater remanence, which is directly proportional to the density increase. Coercivity is also sensitive to the porosity decrease, probably due to a better interlocking of particles. Current results indicate Am as a promising route for near net-shape manufacturing of Sm-Fe-N permanent magnets, a market niche yet to be widely explored.
