ICSYNTH – demo available; proprietary software; A computer aided synthesis design tool that enables chemists to generate synthetic pathways for a target molecule, and a multistep interactive synthesis tree; at its core is an algorithmic chemical knowledge base of transform libraries that are automatically generated from reaction databases.

SCIgen is a paper generator that uses context-free grammar to randomly generate nonsense in the form of computer science research papers. Its original data source was a collection of computer science papers downloaded from CiteSeer. All elements of the papers are formed, including graphs, diagrams, and citations.
Litmus paper after being used. The main use of litmus is to test whether a solution is acidic or basic, as blue litmus paper turns red under acidic conditions, and red litmus paper turns blue under basic or alkaline conditions, with the color change occurring over the pH range 4.5–8.3 at 25 °C (77 °F). Neutral litmus paper is purple. [2]
The SPAAC vs SpANC reaction. Because this reaction is metal-free and proceeds with fast kinetics (k2 as fast as 60 1/Ms, faster than both the CuAAC or the SPAAC) SPANC can be used for live cell labeling. Moreover, substitution on both the carbon and nitrogen atoms of the nitrone dipole, and acyclic and endocyclic nitrones are all tolerated.
Scientific papers published as late as 2008 in the field of organocatalysis use either the 1985, 2001 or 2002 names of the reaction. A June, 2014 search limited to the years 2009–2014 by Google Scholar returns 44 hits for Hajos-Parrish reaction, 3 for Hajos-Parrish-Wiechert reaction and 184 for Hajos–Parrish–Eder–Sauer–Wiechert reaction.
Kraft pulp is darker than other wood pulps, but it can be bleached to make very white pulp. Fully bleached kraft pulp is used to make high-quality paper where strength, whiteness, and resistance to yellowing are important. The kraft process can use a wider range of fiber sources than most other pulping processes.
