📚 Semantic Scholar Search Scraper

This actor allows you to scrape academic papers from Semantic Scholar by providing a search keyword. It automatically handles pagination and extracts comprehensive research paper information including titles, authors, citations, abstracts, publication details, and more.

Features

• Keyword-based Search: Extract academic papers by providing search keywords or phrases
• Automatic Pagination: Automatically scrolls and loads more papers until reaching the end or max items limit
• Comprehensive Research Data: Extract detailed information about each paper including:
  • Paper title and abstract
  • Author information
  • Publication year and venue
  • Citation counts and influential citation metrics
  • Paper IDs (Semantic Scholar, DOI, ArXiv, PubMed, etc.)
  • Field of study classifications
  • TL;DR summaries (when available)

Input Parameters

Field	Type	Required	Description
keyword	string	Yes	Keyword or phrase to search for
maxItems	integer	No	Maximum number of papers to fetch (default: 100)
proxyConfiguration	object	No	Proxy settings for the crawler

		"text": "One challenge for the commercial development of solid oxide fuel cells as efficient energy-conversion devices is thermo-mechanical instability. Large internal-strain gradients caused by the mismatch in thermal expansion behaviour between different fuel cell components are the main cause of this instability, which can lead to cell degradation, delamination or fracture1–4. Here we demonstrate an approach to realizing full thermo-mechanical compatibility between the cathode and other cell components by introducing a thermal-expansion offset. We use reactive sintering to combine a cobalt-based perovskite with high electrochemical activity and large thermal-expansion coefficient with a negative-thermal-expansion material, thus forming a composite electrode with a thermal-expansion behaviour that is well matched to that of the electrolyte. A new interphase is formed because of the limited reaction between the two materials in the composite during the calcination process, which also creates A-site deficiencies in the perovskite. As a result, the composite shows both high activity and excellent stability. The introduction of reactive negative-thermal-expansion components may provide a general strategy for the development of fully compatible and highly active electrodes for solid oxide fuel cells. Highly active but durable perovskite-based solid oxide fuel cell cathodes are realized using a thermal-expansion offset, achieving full thermo-mechanical compatibility between the cathode and other cell components.",
