Sikong, Lek Vo, VanTruong Keywords:  Hybrid electrochromic materials;Sol–gel methods;Electrochromism;Hybrid oxides;Nanomaterials Issue Date:  2017 Publisher:  H. : ĐHQGHN Series/Report no.:  Volume 2;Issue 3 Abstract:  This short review revisits the progress achieved in the last 10–15 years in the field of hybrid electrochromic materials, synthesized through sol–gel methods. New research directions in the field of electrochromism (EC), together with novel applications of many electrochromic hybrid oxides are discussed here. Among them, the discoveries in the field of synthesis of nanomaterials enabled to expand the materials and connect the morphological features of nanoparticles to the electrochromic properties at the macro level. The development of novel hybrid m...

We aimed to determine the relationship between dioxin congeners in maternal breast milk and maternal glucocorticoid levels with newborn birth weight after nearly 45 years of use of herbicides in the Vietnam War. The study subjects comprised 58 mother–infant pairs in a region with high dioxin levels in the soil (hotspot) and 62 pairs from a control region. Dioxin levels in maternal breast milk were measured by HRGC-HRMS. Salivary glucocorticoid levels were determined by LC-MS/MS. Dioxin congener levels in mothers from the hotspot were found to be two to fivefold higher than those in mothers from the control region. Birth weight was inversely correlated with 2,3,7,8-TeCDD and 2,3,4,7,8-PeCDF congener levels. The rate of newborns whose birth weight was less than 2500 g was threefold higher in the hotspot (12 %) than in the control region (4 %). Salivary glucocorticoid levels in mothers with low birth weight infants were significantly higher than those in the normal birth we...
