for 3 days at room temperature. To calculate the amount of loaded DOX, the contents of original DOX and the supernatant were determined by NanoDrop 2000/2000c spectrophotometer (Thermo Fisher Scientific) at 480 nm. The DOX loading efficiency (LE) can be calculated by the following formula: ...
Metalloporphyrin and gold nanoparticles modified hollow zeolite imidazole Framework-8 with excellent peroxidase like activity for quick colorimetric determination of choline in infant formula milk powder 具有优异的过氧化物酶活性的金...
Over the years, bacterial infections have become a threat to global health and the economy. In response to this, there has been the development of various antibacterial drugs. Increased use of such antibacterial drugs has resulted in the genetic drift within the microbial body, leading to the ...
ZIF-8 MOF with chemical formula of Zn[MeIM]2, where MeIM stands for 2-methylimidazole and the sodalite (SOD) topology represents cuboctohedral structure is viewed as a promising ZIF for CO2 separation [24]. Indeed, its aperture pore size (3.4 Å) is between the kinetic diameters of CO2...
Based on EDS and FTIR results, the chemical formula of Zn-5(HMIM)(4)(MIM)(6)(OH)(4) for the building unit of such substance is proposed consisting of four partially hydrolyzed and one undisturbed secondary ZIF-8 building units. The ZIF-8 phase shift substance is crystalline with a ...
The FAME yield was calculated by the following formula: FAME yield (\% )=mi×AsAi×ms×100 where mi and ms represent the mass of internal standard and sample, respectively, Ai and As represent the GC peak area of internal standard and FAMEs, respectively. All data are from triplicated ...
(PSS + SSS) were analyzed towards obtaining the particle radiusRby nonlinear regression. The reported standard errors for the derived parameters are estimated according to the Error Propagation formula by the OriginPro fitting software. Note that for AR-SHS measurements of polarization combinations...

QF is calculated by the following formula:(2)QF=−ln(1−η)/ΔP 2.4. Efficient filtration at high face velocity A diaphragm vacuum pump was used to simulate industrial high pressure rapid filtration of particulate matter. The air flow rate is 20 L/min, which is converted into a face ...
The impedance of the CPE was computed by the following formula [49]:ZCPE=1Y0jωnwhere Y0 represents the proportional factor, ω is the angular frequency, and n is an adjustable parameter (0 ≤ n≤ 1). The equivalent-circuit model based on the Bode diagram is shown in Fig. 11. Fig....
