Binary additives of polyamide epichlorohydrin-nanocellulose for effective valorization of used paper.

This paper presents a binary reinforcement system of polyamide polyamine epichlorohydrin with nanocellulose (PAE-NC) for effectively modification of the reclaimed fibres for paper production, and based on the improvement of physical and mechanical properties of cellulosic fibres together with PAE-NC self-crosslinking networks, the strengthening mechanisms of recycled papers are examined. The PAE-NC binary system was applied directly to old corrugated container (OCC) and softwood bleached kraft pulp (SWBKP), and handsheets are prepared with varying amounts of PAE/NC/PAE-NC, namely 0.05, 0.

Clinical analysis of an anchor nail combined with a titanium cable in the treatment of lower patella fractures.

Objective: This study was performed to evaluate the clinical effect of an anchor nail and titanium cable for lower patella fractures and identify an effective treatment.

Methods: Thirty-five patients with lower patella fractures were treated using anchor nail and titanium cable technology. The anchor was fixed to the main part of the patella; the lower patella was then fixed.
