Other research groups were not able to replicate the results and suggested that impurities in the material led to spurious effects mimicking phenomena associated with superconductivity. Copper(I) sulfide , a compound produced in the synthesis process, turned out to be a close match for the claimed properties of LK-99, and pure samples of LK-99 ...
Steven S. Rosenfeld (US), a former Harvard undergraduate, forged letters of recommendation for himself in the name of David Dressler, whose laboratory he used. His research on transfer factor, on which two articles were published in the Proceedings of the National Academy of Sciences and one article in Annals of Internal Medicine, could not be ...
A scientist at a research laboratory in Australia got infected with Dengue through a mosquito bite in the laboratory. [51] 2012 Anthrax United Kingdom The UK's Animal and Plant Health Agency sent out live samples of anthrax by mistake. Its Surrey lab was subject to a Crown Prohibition Notice (CPN), closing it until improvements were made. [52 ...
Research integrity or scientific integrity became an autonomous concept within scientific ethics in the late 1970s. In contrast with other forms of ethical misconducts, the debate over research integrity is focused on "victimless offence" that only hurts "the robustness of scientific record and public trust in science".

Schön's topic of research was condensed matter physics and nanotechnology. [3] He received his PhD from the University of Konstanz in 1997. During late 1997, he was hired by Bell Labs, where he worked on electronics in which conventional semiconducting elements (such as silicon) were replaced by crystalline organic (meaning carbon-based) materials.
For example, an experimental uncertainty analysis of an undergraduate physics lab experiment in which a pendulum can estimate the value of the local gravitational acceleration constant g. The relevant equation [ 1 ] for an idealized simple pendulum is, approximately,
AQC is achieved through laboratory control of analytical performance. Initial control of the complete system can be achieved through specification of laboratory services, instrumentation, glassware, reagents, solvents, and gases. However, evaluation of daily performance must be documented to ensure continual production of valid data.
The Sheri Sangji case is the first criminal case resulting from an academic laboratory accident. [1] [2] [3]The case arose from a fatal accident that occurred in the chemistry laboratory of Patrick Harran at the University of California at Los Angeles (UCLA).
