| Abstract | Superamphiphobic (both superhydrophobic and superoleophobic) surfaces on Al substrates are fabricated by the high speed wire electrical discharge machining (HS-WEDM) and chemical etching technology. The surface morphology, chemical composition and wettability of the sample surfaces are investigated using scanning electron microscopy, energy dispersive X-ray diffraction system and optical contact angle (CA) measurements. The results show that, after the HS-WEDM and chemical etching, the micrometer-scale craters and nanometer-scale acicular structures are present on the sample surfaces. The obtained sample surfaces show superamphiphobicity after fluorination. The CAs of water, ethylene glycol and peanut oil are 155.9°, 153.1° and 151.7°, respectively. The sliding angles of water, ethylene glycol and peanut oil are 2°, 3.5° and 5°, respectively. The micro/nanometer-scale rough structures and the low surface energy are essential to fabricate superamphiphobic surfaces. Compared with the other methods, the main advantages of the HS-WEDM and chemical etching technology are simple, safe, highly effective and low cost. In addition, superamphiphobic Al surfaces have potential applications in fields such as self-cleaning, oil capture, oil transportation and anti-smudge. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
