The pristine points of zero charge (PZC) and isoelectric points (IEP) of metal oxides and IEP of other materials from the recent literature, and a few older results (overlooked in previous searches) are summarized. This study is an update of the previous compilations by the same author [Surface Charging and Points of Zero Charge, CRC, Boca Raton, 2009; J. Colloid Interface Sci. 337 (2009) 439; 353 (2011) 1; 426 (2014) 209]. The field has been very active, but most PZC and IEP are reported for materials, which are very well-documented already (silica, alumina, titania, iron oxides). IEP of (nominally) Gd₂O₃, NaTaO₃, and SrTiO₃ have been reported in the recent literature. Their IEP were not reported in older studies.

归纳了最新文献中金属氧化物的零电荷原始点（PZC）和等电点（IEP）以及其他材料的IEP，并总结了一些较旧的结果（在先前的搜索中被忽略）。这项研究是同一作者先前汇编的更新[表面充电和零电荷点，CRC，博卡拉顿，2009年；J.胶体界面科学。337（2009）439; 353（2011）1；426（2014）209]。该领域一直很活跃，但是据报道大多数PZC和IEP都是针对材料的，这些材料已被充分记录（二氧化硅，氧化铝，二氧化钛，氧化铁）。在最近的文献中已经报道了（名义上）Gd ₂ O ₃，NaTaO ₃和SrTiO _3的IEP 。他们的IEP在较早的研究中没有报道。
