CaO2 reacts with water (H2O) to produce calcium ion (Ca2+), oxygen (O2), and hydrogen peroxide (H2O2), where Ca2+ is suitable for calcium death caused by calcium overload, O2 is suitable for...

Apr 15, 2018 · In a similar study involving PEG-synthesized CaO 2 NPs, transmission electron microscopy (TEM) images showed the particle sizes were around 15–25 nm (Khodaveisi et al., 2011). More recently, CaO 2 NPs also had a good remediation efficiency of benzene in groundwater ( Mosmeri et al., 2017 ).

Calcium peroxide (CaO2), which can effectively generate hydrogen peroxide (H2O2) in the absence of oxygen, offers a potential solution to this issue. Many methods have been reported for the preparation of CaO2 powders with micrometer and nanometer sizes.

Jun 19, 2018 · Herein, we report a facile, template-assisted synthesis approach to yield a highly effective, MgO-stabilized, CaO-based CO 2 sorbent that relies on environmentally benign precursors. The...

The CaO2 nanoparticles show a very dark image of HR-TEM because CaO2 nanoparticles possess a higher electron density. The particles were shown as single and isolated because of presence of...

Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) images of CaO 2 @DOX@ZIF-67 revealed monodisperse nanospheres with a mean diameter of 200 nm ( Figure 1 a,b). This...

Nov 11, 2021 · Here, we report a porphyrin-based metal–organic framework combined with hyaluronate-modified CaO 2 nanoparticles (PCN-224-CaO 2 -HA) to target and enhance PDT efficacy. CaO 2 reacts with H 2 O or weak acid to produce O 2, overcoming the hypoxia problem.

Dec 1, 2022 · CaO 2 NPs efficiently regulated the TME and improved the antitumor effect of doxorubicin under hypoxia conditions in vitro.

Dec 25, 2024 · The morphology and shell structure of CuO@CaO 2 NSs were analyzed by transmission electron microscopy (TEM, Technai, FEI, Thermo Fisher Scientific, Oregon, U.S.A.). The crystalline structure was evaluated by X-ray diffraction (XRD) spectrophotometer (Rigaku Ultima-IV, Japan).

Sep 5, 2016 · In this research, a novel productive method to synthesize high-purity nanoparticle was reported. Ca (NO3) 2 was used as an effective precursor under mild conditions. High-purity CaO 2 with nanosized spherical particle was observed.
