Effect of transfer roller surface profile on discharge mark

Ryosuke Hamamoto、Yasuo Yoda、Hiroyuki Seki 等 6 位作者2011-01-01Technical programs and proceedings/Technical program and proceedings

In this report, we discuss the reason why transfer roller surface profile affects the discharge mark, and propose a new roller model for numerical simulation. Our observation has revealed that the discharge mark depends on the surface profile of transfer rollers, the conventional foam roller, smooth roller which has a…

Polymer Stabilized Pigment Dispersions for High Reliability Ink-Jet Printing

Tom Annable、Owen R. Lozman、Paul Ewing2011-01-01Technical programs and proceedings/Technical program and proceedings

Due to their excellent water and fade resistance properties and their low environmental impact, aqueous pigment dispersions are of growing importance in emerging high throughput aqueous ink jet markets. However, the physical durability (abrasion resistance) of pigment-based inks is often poor. In this paper we describ…

Computational and Experimental Study of Colloidal Stability of CuPc Aqueous Dispersions

Yan Zhao、Hou T. Ng、Eric G. Hanson 等 6 位作者2011-01-01Technical programs and proceedings/Technical program and proceedings

Dispersions of copper phthalocyanine (CuPc) pigments are commonly used in digital printing. Their colloidal stability is essential for fulfilling desirable shelf life and achieving good printing performance. In order to understand the role of electrostatic and van der Waals forces in their stability, a combined comput…

Technological advances in electrospinning of nanofibers

Ryuji Inai and Seeram Ramakrishna Wee-Eong Teo2011-01-01DOAJ (DOAJ: Directory of Open Access Journals)

Progress in the electrospinning techniques has brought new methods for the production and construction of various nanofibrous assemblies. The parameters affecting electrospinning include electrical charges on the emerging jet, charge density and removal, as well as effects of external perturbations. The solvent and th…

Mn-Co-Zn-O体系制备低阻高B型单层片式NTCR

贾素兰、陈朝阳、陶明德 等 4 位作者2011-01-01Acta Scientiarum Naturalium Universitatis Sunyatseni

研究了Mn-Co-O体系通过掺入适量ZnO,采用最佳的烧结温度,可制备低阻高B型NTCR(负温度系数热敏电阻),并通过XRD、SEM研究了样品Mn1.14Co1.83Zn0.03O4在不同烧结温度下的微观结构和电学特性。结果表明:Mn-Co-Zn-O体系在T=1100~1200℃很宽的温度范围可只存在尖晶石结构,同时具有高的激活能。样品Mn1.14Co1.83Zn0.03O4在烧结温度T=1100℃时存在最小电阻率,而B仍保持在4046K左右。因此,由其制成的单层片式NTCR可替代某些具有内电极的叠层器件。

时效对Cu-Ag-Fe合金组织及性能的影响

Yong Li、易丹青、柳瑞清2011-01-01材料热处理学报

研究了时效对Cu-0.15Ag-0.1Fe合金的显微硬度、抗拉强度和电导率的影响。结果表明:随着时效时间的增加和时效温度的升高,Cu-0.15Ag-0.1Fe合金的显微硬度和抗拉强度先急剧增加随后逐渐降低;合金经960℃×1 h固溶,在500℃时效2 h后可获得较好的显微硬度和抗拉强度,分别为124 HV和442 MPa;当时效时间增加到6 h,可获得较高的电导率,达到82.5%IACS。通过透射显微镜分析,该合金中的强化相是γ-Fe粒子,与以前报道的Cu-Fe系合金的析出强化相是α-Fe不同。

Biopolymer-based nanocomposites: effect of lignin acetylation in cellulose triacetate films

Lourdes Ballinas Casarrubias Laura Alicia Manjarrez Nevárez2011-01-01DOAJ (DOAJ: Directory of Open Access Journals)

We have prepared all-biopolymer nanocomposite films using lignin as a filler and cellulose triacetate (CTA) as a polymer matrix, and characterized them by several analytical methods. Three types of lignin were tested: organosolv, hydrolytic and kraft, with or without acetylation. They were used in the form of nanopart…
