Metal-Coordination-Induced Fusion Creates Hollow Crystalline Molecular Superstructures

“…These observations indicate that the TPEPA crystals indeed constitute the building blocks of the superstructures. Additional peaks with 2θ values of 11.6, 12.5, and 23.3 are compatible with d spacings of Cu salts, such as Cu 2 (NO 3 )­(OH) 3 and (NH 4 )­CuCl 3 . , Cu 2 (NO 3 )­(OH) 3 was observed by PXRD when solubilizing Cu­(NO 3 ) 2 in DMF/CHCl 3 (3:1 v/v) . The formation of a copper chloride salt is consistent with the EDS and XPS data (Figure , Chart 2A; Figure S12).…”

The anti SARS-CoV-2 activity of nanofibrous filter materials activated with metal clusters

“…4 ). In the case of material electrospun using a solution of 28 wt% PVDF + DMA +2 wt% Cu(NO 3 ) 2 ·2.5H 2 O there are reflections at 2 θ ∼12.9° and ∼25.8° not corresponding to the Cu(NO 3 ) 2 ·2.5H 2 O but to the “basic copper nitrate” Rouaite (Cu 2 (NO 3 )(OH) 3 ) that is a dehydration product of Cu(NO 3 ) 2 ·2.5H 2 O obtained at ∼ 80 °C ( Cseri et al, 1996 ; Richardson, 2000 ; Sumathirathne and Euler, 2021 ). The decomposition of Cu(NO 3 ) 2 ·2.5H 2 O to “basic copper nitrate” is probably caused by the high electric field strength applied in the electrospinning process.…”

Limitation of Plant Biopesticides

“…Applications to crop protection (stored product pests), mosquito repellency (citronella oil), control of domestic pests (cockroaches, ants, fl eas, etc. ), Varroa mite control, as aphicides and acaricides (cinnamon oil) and urban insect control (eugenol-based products from basil or clove) have been reported (Regnault-Roger et al 2005 ) A range of insecticide products may be also blends of plant oils, such as rosemary, clove, peanut oil, thyme, lemon grass, cinnamon or pennyroyal as components (Isman 2000 ). Other used botanical insecticides approved for use in specifi c countries are presented in Table 17.1 .…”

“…monoterpenes). However, s tability in the environment and prolonged persistence time have been studied recently and in some cases even addressed in various formulations of the BIs (Regnault-Roger et al 2005 ;Isman 2006 ;Pavela 2012 ).…”
