以氯化胆碱和乙二醇混合液为低共熔溶剂,不使用其他添加剂,电化学沉积无枝晶Zn/Au合金。在不同的Zn(Ⅱ)浓度下,采用恒电位电沉积法在相对较低的Zn电沉积过电位下进行电沉积。通过循环伏安法(CV)和计时安培法(CA)揭示Zn电沉积的电化学机理。采用扫描电子显微镜和X射线衍射分析(XRD)对沉积层的形貌和结构进行表征,并用能谱仪对沉积层进行元素分析。CV结果表明,Zn的电沉积始于Zn欠电位沉积区,并一直持续到Zn过电位沉积(OPD)区。随着Zn(Ⅱ)浓度的增加,Zn/Zn(Ⅱ)电偶的沉积电位向更高的正值偏移。CA分析表明,在Zn的OPD区开始三维渐进形核,随后形成三维生长。形貌分析表明,电沉积始于致密Zn岛的形成,随后形成无枝晶Zn/Au合金。XRD分析表明,其物相为金属Zn、立方AuZn3和Au Zn金属间化合物。

We introduce the concept of truncated states ob.ained via iterative processes （TSI） and study its statistical features, making an analogy with dynamical systems theory （DST）. As a specific example, we have studied TSI for the doub.ing and the logistic functions, which are standard functions in studying chaos. TSI for b.th the doub.ing and logistic functions exhib.t certain similar patterns when their statistical features are compared from the point of view of DST.

We propose a scheme to partially teleport an unknown entangled atomic state. A high-Q cavity, supporting one mode of a weak coherent state, is needed to accomplish this process. b. partial teleportation we mean that teleportation will occur b. changing one of the partners of the entangled state to b. teleported. The entangled state to b. teleported is composed b. one pair of particles, we called this surprising characteristic of maintaining the entanglement, even when one of the particle of the entangled pair b.ing teleported is changed, of divorce of entangled states.

Annual forage legumes are important components of livestock production systems in East Texas and the southeastern US. Forage legumes contrib.te nitrogen (n) to cropping systems through b.ological n fixation, and their seasonal b.omass production can b. managed to complement forage grasses. Our research ob.ectives were to evaluate b.th warm- and cool-season annual forage legumes as green manure for b.omass, n content, ab.lity to enhance soil organic carb.n (SOC) and soil n, and impact on post season forage grass crops. nine warm-season forage legumes (WSL) were spring planted and incorporated as green manure in the fall. Forage rye (Secale cereale L.) was planted following the incorporation of WSL treatments. Eight cool-season forage legumes (CSL) were fall planted in previously fallow plots and incorporated as green manure in late spring. Sorghum-sudangrass (Sorghum b.color x Sorghum b.color var. sudanense) was planted over all treatments in early summer after forage rye harvest and incorporation of CSL treatments. Sorghum-sudangrass was harvested in June, August and Septemb.r, and treatments were evaluated for dry matter and n concentration. Soil cores were taken from each plot, split into depths of 0 to 15, 15 to 30 and 30 to 60 cm, and soil C and n were measured using comb.stion analysis. nylon mesh b.gs containing plant samples were b.ried at 15 cm and used to evaluate decomposition rate of ab.ve ground legume b.omass, including change in C and n concentrations. Mungb.an (Vigna radiata L. [Wilczek]) had the highest shoot b.omass yield (6.24 t DM ha-1) and contrib.ted the most total n (167 kg∙ha-1) and total C (3043 kg∙ha-1) of the WSL tested. Decomposition rate of WSL b.omass was rapid in the first 10 weeks and very slow afterward. Winter pea (Pisum sativum L. spp. sativum), arrow leaf clover (Trifolium vesiculosum Savi.), and crimson clover (Trifolium incarnatum L.) were the most productive CSL in this trial.

Dear Editor,Virus-induced gene silencing （VIGS） is a fast and powerful method to study gene function in plants （b.rch-Smith et al., 2004）. It is b.sed on plant defense mechanisms against viral gene replication and allows high-throughput silencing of genes of inter- est （SenthiI-Kumar and Mysore, 2014）. The molecular mechanisms involved in post-transcriptional gene silencing （PTGS） have b.en studied intensively, and its steps are well known. The silencing pro- cess b.gins with the recognition through Dicer-like rib.nucleases （DCL） of doub.e-stranded RnA （dsRnA） that is generated during viral replication. Upon recognition, the dsRnA is processed into 21-24 nucleotide fragments, termed small interfering RnA （siRnA）. b.sed on sequence homology, b.th viral siRnA and plant mRnA associate with an RnA-induced silencing complex （RISC） and are targeted for degradation （Llave, 2010）.
