牛仔水洗条件与靛蓝沾色的关系

模拟生产实际情况，收集纯靛蓝牛仔布水洗残液进行靛蓝染料的再沾色试验。通过测定白衬布的R值，定量分析沾色的程度，研究了水洗温度、pH值、纤维素酶种类、表面活性剂以及水洗时间对沾色的影响。结果表明，影响靛蓝再沾色的主要因素是纤维素酶种类、表面活性剂以及水洗时间，而温度、pH值的影响较小。     

纯棉机织物生物酶前处理

采用退浆酶CTA-AL1和煮练酶A、B对纯棉机织物进行前处理,对退煮漂三步法和退煮-浴后氧漂工艺中酶的选择,及其用量、pH值、温度、时间等工艺参数进行正交试验分析。试验表明,退浆酶和煮练酶的相容性好,退煮-浴法和退煮漂三步法生物前处理效果与传统方法基本相当。退煮-浴法的煮练酶用量1.0g/L,退浆酶CTA-AL1用量3.0g/L,精练漂白剂ST-09用量1.0g/L,在pH值为8.0下处理50min,而后进行漂白;退煮漂三步法则先用退浆酶CTA-AL13.0g/L处理20min,而后用1.0g/L的煮练酶B处理50min,最后进行漂白。

A modified spray-winding approach to enhance the tensile performance of array-based carbon nanotube composite films

A carbon nanotube (CNT) array based spray-winding approach for CNT film fabrication was developed by adding a post hot-pressing process, and an epoxy solution was used to fabricate CNT/epoxy composite film. It showed that the hot-pressing process benefited the load transfer within CNT films by reducing the porosity among CNT bundles and was more efficient in improving the tensile properties of few wall CNT films. The epoxy modified multi-wall CNT film exhibited a tensile strength and modulus of 1540 MPa and 59 GPa, respectively. From the results of scanning electron microscopy and measurements of contact angle, Raman spectroscopy and thermogravimetric analysis, the main mechanism of the improvement was attributed to good wettability of CNT film with epoxy, high degree of CNT alignment, and high CNT load in the CNT film.     

An amendment to the classical model of internal oxidation: Model-inherent transition characteristics

An analytical method based on the flux balance at the inter-region boundary is explored for the evolution of a binary alloy in the corresponding Rhines pack atmosphere where the solute forms only one type of oxide. This alloy may undergo an exclusive external oxidation, an exclusive internal oxidation or a mixed oxidation. The assumption of zero solubility-product is very restrictive for a complete analysis of the mixed oxidation. Nevertheless, an analysis of the exclusive internal oxidation, improved upon the classical theory, gives the transition characteristics and hence a domain of the existence of this possibility.     

Highly selective reductive cleavage of aromatic carbon–oxygen bonds catalyzed by a cobalt compound

A cobalt catalyst has been demonstrated, for the first time, to be effective for the reductive cleavage of inert aromatic CO bonds with high selectivity. Compared with previous Ni catalysts, the cobalt catalyst reported here is more commercially available and air-stable.
