In vitro culture, cryopreservation, and field reintroduction of the endangered Mingan thistle
Abstract Current plant conservation efforts are hindered by, for example, poor seed germination, low viability, and insufficient propagation and preservation technologies. To address these problems, we devised an approach to plant conservation that integrates conservation, preservation, and restoration (CPR), which uses advanced in vitro techniques. We

ABSTRACT MCrAlX coatings are widely used as bond coats in thermal barrier coating systems to protect turbine blades from high‐temperature oxidation. However, their oxidation resistance is often restricted by uncontrolled microstructures, surface roughness, and aggregation of reactive elements (REs). In this study, high‐repetition‐rate femtosecond laser

Study on the Removal of Nitrogen Oxide from Diesel Engine Exhaust by Non-thermal Plasma Facilitated with Conventional Denitrification Process [PDF]
氮氧化物(NOx)是重要的大气污染物之一,有N2O、NO、N2O3、NO2、N2O5等多种形态,柴油器尾气中的NOx主要以NO和NO2的形态存在。大气中的NOx主要来源于燃煤电厂、水泥行业和内燃机的废气排放,会造成光化学烟雾、酸雨等大气污染现象,刺激人的眼、鼻、喉、肺,危害人类健康。作为内燃机中的主要机型,柴油发动机广泛应用于发电机组、工农业机械和交通运输等领域,产生的废气是大气中NOx的重要来源之一。目前用于降低柴油机尾气中NOx含量的技术主要是燃油高压喷射、增压中冷、废气再循环等机内控制技术 ...

Study on Preparation and Application of Adhesive for Polyolefin Film [PDF]
由于具有较高的机械强度、良好的化学稳定性、较好的电绝缘性、优良的加工性等优势,聚烯烃塑料广泛应用于社会生活中。在众多的聚烯烃塑料制品中,最为常见的产品是薄膜制品,包括聚乙烯薄膜、聚丙烯薄膜、多层共挤聚烯烃薄膜等。为了获得更优异的性能,实际应用中一般将聚烯烃薄膜与自身或者其他薄膜(如铝箔、聚酰胺薄膜、聚酯薄膜等)进行复合使用。目前,在复合过程中常用的聚烯烃薄膜粘结剂存在以下两个问题:1、环保问题:目前国内广泛使用的酯溶型聚氨酯粘结剂可能含有异氰酸酯单体的残留,而水性粘结剂由于干燥速度慢 ...

ABSTRACT Ceramic capacitors are critical components in advanced electronic devices, primarily due to their multi‐functionalities in energy/information storage and conversion. However, poor temperature stability remains a long‐standing challenge for practical applications, especially at extremely high‐ or low‐temperature conditions (e.g., > 200°C or ...
