Determination of Copper and Chromium in the Cartridges of Permanent Marker Pen and Ink by ICP-AES;

Application of polymers in ink manufacture;

Application of surfactants in ink manufacture;

In our society, Forensic examination often involves questioned documents and requires to determine the date of writing inks.

But until now, questioned documents and dating writing inks is one of difficult problem in forensic science due to the complex composition and detection interfere of ink.

A Study on BOD/DO Water Quality Model of Moshui Lake;

Assessment on pollution status of heavy metal in sediment of Moshui Lake in Wuhan;

Moshui Lake is a representative of urban lakes heavily polluted by heavy metals in China.

The carbon black dispersion for aqueous ink was prepared by sand mill.

Dye disposed by membrane separation as colorant, diethylene glycol (DEG) as solvent and selecting other additives such as surfactant, lubricant, pH-adjusting agent, rust preventive, aqueous ink whose physical properties index and writing properties approach or reach import ink was made.

Preparation of electrophoretic ink using urea-formaldehyde oligomer;

Preparation and performance of green encapsulated electrophoretic ink;

Study on preparation and curing of urea-formaldehyde resin microcapsule for electrophoretic ink;

Different kinds of dispersants were tested and the carbon black dispersion for gel ink was prepared.

This paper analyzes the connection between dye decentralization and stability of gel ink, expounds the stability mechanism of gel ink, plus, it excogitate an experiment methods which could accurately evaluate the stability of gel ink at short notice.

China is the largest producer of Gel ink ball-point pen, with its output in recent years has been ranking first in the world, but this should be a relatively neutral pen manufacturing is the core material - Gel-ink still rely mainly on imports.
