Effects of deposition angle and axial distance on the structural and mechanical properties of niobium nitride synthesized by a dense plasma focus(DPF) system are studied.The x-ray diffraction(XRD) confirms that the deposition parameters affect the growth of multi-phase niobium nitride.Scanning electron microscopy(SEM)…
Poly(ethyl α-cyanoacrylate)(PECA) hollow nanofibers were fabricated directly by means of onepot monomer solution casting method. The diameter of the PECA nanofibers was 50—100 nm. The whole process was simple,rapid and took place at room temperature. Three solution systems ECA/Ti Cl4/ CHCl3,ECA/HCl/acetone and ECA/HCO…
The synergistic inhibition effect of MoO42-and NO2-on pitting corrosion of mild steel was studied by polarization curve, electrochemical impedance spectroscopy(EIS), Mott-Schottky plot, and X-ray photoelectron spectroscopy(XPS). The results showed that the metastable pitting potential(Em) and the pitting breakdown pot…
By using liquid exfoliation method with sonication in appropriate stripping solvent,ultrasonic time,ultrasonic power,MoS2 hybrid-nanosheets suspension with different lateral dimension and uniform dispersion nanosheets were obtained. Under 360 nm excitation,the suspension shows both the luminescence properties of monol…
103 surface sediment samples in 71 water bodies,such as lakes with different salinity,swamps,shallow puddles and rivers on the Qinghai-Tibetan Plateau(QTP),were collected to study the ecological distribution of living ostracods and their environmental implications. Total of 12 genus and 45 species living ostracods are…
인체에 무해하고 대표적인 친환경소재로서 잘 알려진 Polylactic Acid (PLA)는 최근 기후 변화로 인한 저탄소 시대 실현 요구를 충족시킬 친환경소재로서, 또한 기존의 범용 석유화학제품의 대안으로서 많은 주목을 받아왔고 다양한 제품응용 개발을 위한 연구가 진행되어 왔다. 하지만, PLA는 우수한 생분해성으로 선순환적자원순환에 기여할 수 있지만, 낮은 내열성으로 인해 범용 석유화학제품들을 대체하기 위한 활용성에 많은 제약을 받아왔다. CJ제일제당은 이러한 PLA의 물성적 한계를 개선하고 제품 응용분야 확대를 위해 고내열성 PLA(ex. Sc-PLA)의 원료…
一系列 monomethoxy (乙烯乙二醇)(mPEG ) poly， grafted copolyglutamates (PmPEGs ) 通过按化学跟随的戒指洞聚合(ROP ) 被综合。超分子的 hydrogels 基于在 PmPEG 和 -cyclodextrin 之间的聚合物包括建筑群(IC )(-CD) 在水的答案被准备。rheological 大小显示他们的冻结性质被几个因素包括 mPEG 长度，接枝密度和样品集中影响。这些 hydrogels 由于可逆 mPEG 和 CD 包括 complexation 在适当条件下面显示了 thermo 敏感的胶化大音阶的第五音转变。这些 hydrogels 也由于羧基的酸方面组…

Electronically complementary, low molecular weight, low viscosity polymers that can self-assemble through tuneable π-π stacking interactions have been developed for inkjet printing applications.1 To this end, three printing techniques have been used to successfully deposit supramolecular materials, resulting in facile…
We investigate the unique properties of current-induced heat generation in nanojunctions,such as failed Q α I relation(where Q is the heat generation and I the current),threshold voltage required to generate heat,etc.By employing the lead-quantum dot(QD)-lead system,we find these unique properties stem from(i) the dis…
Molecular dynamics(MD) simulations were performed to stretch the rectangular graphene sheets doped with silicon, nitrogen or boron atoms. Young’s modulus, ultimate stress(strain) and energy absorption were measured for the graphene sheets with the doping concentration(DC) ranging from 0 to 5%. The emphasis was placed…
C 在低镍的生铁与增加的锰内容被观察。在 erosioncorrosion 测试下面，生铁的重量损失率与增加时间增加。穿戏一个更重要的角色比在决定重量损失的腐蚀。为有高、低的镍内容的生铁的重量损失的过程是不同的，这被显示。包含 7.29wt% 镍和 6.94wt% 锰的生铁的侵蚀抵抗等价于包含 13.29wt% 镍的生铁的。
The phosphorus-containing PODIPY 1 as a chemosensor can detect Hg2+ by a color change from pink to violet red without the use of any instrumentation. PODIPY 1 was selective to Hg2+with a remarkable absorption change, and addition of other relevant metal ions caused almost no absorption change. The new PODIPY dye 1 was…
In order to tackle the shortcomings of high brittleness,hard graphitization,and poor oxidation resistance resulted from carbonization of phenolic resin of Mg O- C refractories, effects of 2 mass% spherical Ni, and2 mass% spherical Ni plus 7. 5 mass% Al composite powder on microstructure of the secondary carbon in Mg O…
显著地被增加，当 10-OH-NBP 的显示出忽视然而并非统计上重要的增加时。有 NBP 的老鼠大脑 homogenate 的孵化产出 3-OH-NBP 然而并非 10-OH-NBP .Conclusion : 越过老鼠的 BBB 的 10-OH-NBP 和 3-OH-NBP 的异构体选择的分发主要在血浆和大脑蛋白质绑定和 3-OH-NBP 的流出运输被归因于差别。丰富的 10-OH-NBP 没在老鼠大脑被产生。
The aero turbine is spun by high-temperature and high-pressure burning gases. The practice has proven that the directional solidification(DS) turbine blade with perfect column grains has still excellent high-temperature performance in this kind of working environment. This means that the size and orientation of column…
