Functionalized lignin nanoparticles prepared by high shear homogenization for all green and barrier-enhanced paper packaging

Resources Chemicals and Materials
Paper-based materials made from cellulose have been sought after as a sustainable and inexpensive packaging option. However, the porous structure and high hydrophilicity of paper-based materials result in inadequate water and oil repellency, as well as a

Understanding the paradox of primary teacher shortage in low‐income countries: Insights from Malawi

British Educational Research Journal, EarlyView.
Abstract Malawi faces a persistent and chronic teacher shortage, particularly at the primary school level, with much of the challenge attributed to teacher supply constraints. While the causes of teacher shortages are known to be complex and context‐dependent, there remains a lack of in‐depth, country‐specific research to guide effective policies ...

Quiver Subtractions

, 2018
We study the vacuum structure of gauge theories with eight supercharges. It has been recently discovered that in the Higgs branch of $5d$ and $6d$ SQCD theories with eight supercharges, the new massless states, arising when the gauge coupling is taken to

A Chandra Study of the Lobe/ISM Interactions Around the Inner Radio Lobes of Centaurus A: Constraints on the Temperature Structure and Transport Processes [PDF]

, 2007
We present results from deeper {\em Chandra} observations of the southwest radio lobe of Centaurus A, first described by Kraft et al. (2003). We find that the sharp X-ray surface brightness discontinuity extends around $\sim$75% of the periphery of the ...
