LK-99 Perpetual Review: A Collaborative Effort to Curate a Living Document on the Discovery of LK-99

Greetings, fellow enthusiasts of scientific breakthroughs! We are excited to kickstart an initiative focused on gathering resources and creating a comprehensive living document about LK-99.

The material has been claimed to exhibit superconductivity at room temperature, a potential game-changer in the world of physics and technology. The news of such a discovery has stirred lots of conversation, both online and offline, generating interest among scientists and the general public. However, following the publication of the discovery, conflicting reports have started to surface online, creating confusion about whether we are indeed witnessing a potential breakthrough or not.

ResearchHub aims to be the place where researchers and science enthusiasts can openly share, discuss, and create scientific content that can be consumed openly. Thus, by collaborating and pooling our collective knowledge, we aim to create a living document that will serve as an up-to-date reference for researchers, enthusiasts, and curious minds alike.

Objective:

The primary goal of this effort is to compile a diverse range of resources related to LK-99, including research papers, tweets, articles, videos and any other relevant content. By curating an extensive collection of information, we can create a running document where anyone interested in the topic can access the latest findings and developments.

How to Contribute:

Share Research Papers: If you come across scientific papers, preprints, or conference proceedings related to LK-99, please provide the title, authors, publication details, and a link (if available). This will help us build a robust collection of scholarly research.
Curate Tweets and Social Media Updates: Twitter and other social media platforms often serve as a valuable source of real-time updates and discussions. If you encounter tweets, threads, or posts from reputable scientists, researchers, or organizations discussing LK-99, share the relevant links, screenshots, or summaries.
Submit Articles and News Coverage: News articles, blog posts, and magazine features can provide valuable insights into the latest developments surrounding LK-99. If you come across any noteworthy pieces, kindly share the title, author, publication, and a link.

Guidelines for Contributions:

Ensure the resources you share are authentic, reliable, and from reputable sources.
Include proper citations or attributions for research papers, articles, and other scholarly content.
Respect intellectual property rights and avoid sharing copyrighted materials without permission.
Keep the discussions and interactions respectful and focused on the topic.

Let's Build the Future Together:

By collaborating and harnessing the power of collective intelligence, we can foster a community-driven effort to compile a comprehensive and up-to-date list of resources on LK-99. Together, we can accelerate scientific progress and enable easier access to knowledge for researchers, students, and enthusiasts worldwide. To incentivize participation and express gratitude to contributors, we will be awarding RSC to individuals whose submissions are deemed helpful and relevant. These tokens can be used to support future research initiatives.

Join us in this exciting endeavor by contributing your resources and spreading the word. Together, let's unlock the immense potential of open science and pave the way for future collaborations across different disciplines.
