Khaldi Mohammed Elhadi submitted the phtitration package. Version: 1.0.0 2026-08-16 License: mit Summary description: Draw highly accurate pH titration curves using TikZ and pgfplots Announcement text: ------------------------------------------------------------------------ I am pleased to announce the initial release (v1.0.0) of the phtitration package. This package provides LaTeX macros to render highly accurate pH-metric titration curves using TikZ and pgfplots. By employing exact mass and charge balance parametric equations, it ensures smooth, continuous curves without the visual breaks typical of piecewise approximations. Key features: - Supports 8 standard acid-base titration types (including polyprotic). - Automatically draws the tangent method (méthode des tangentes) at equivalence points. - Highly customizable styles, coordinate labels, and units. Thank you! ------------------------------------------------------------------------ The package’s Catalogue entry can be viewed at https://ctan.org/pkg/phtitration The package’s files themselves can be inspected at https://mirrors.ctan.org/graphics/pgf/contrib/phtitration/ ------------------------------------------------------------------------ Thanks for the upload.

New on CTAN: biblatex-apa-zh
by CTAN Announcements via ctan-ann 15 Aug '26

Che Cheng submitted the biblatex-apa-zh package. Version: 0.2.0 2026-08-15 License: lppl1.3c Summary description: APA 7 citation rendering for Traditional Chinese prose Announcement text: -------------------------------------------------------------------------------- biblatex-apa-zh adapts APA 7 citation rendering to Traditional Chinese prose. It is a companion package for biblatex-apa, which ships localisation files for more than twenty languages, but none for Chinese. The package separates two things that are easy to conflate. The language of the running text determines citation punctuation, and is set by a package option: Chinese prose takes full-width parentheses and commas. The language of each cited work determines its name strings and the punctuation of its bibliography entry, and is read from the langid field of that entry, so a single reference list may mix Chinese and Western works. Unlike the autolang mechanism of biblatex, it does not require babel or polyglossia, which makes it usable in the common xeCJK setup. The strings and bibliography punctuation follow the traditional Chinese academic convention as used in Taiwan. Simplified Chinese conventions differ and are not covered by this release. The package ships a test suite that asserts on the rendered output and exits non-zero on any mismatch. -------------------------------------------------------------------------------- This package is located at https://mirrors.ctan.org/macros/latex/contrib/biblatex-contrib/biblatex-apa… More information is at https://ctan.org/pkg/biblatex-apa-zh -------------------------------------------------------------------------------- Thanks for the upload.
