Abstract: Naringenin (NRG), a flavonoid compound, had been reported to exhibit extensive pharmacological effects, but its water solubility and oral bioavailability are only ~46±6 µg/mL 5.8%, respectively. The purpose of this study is design develop NRG-loaded solid lipid nanoparticles (NRG-SLNs) provide prolonged sustained drug release, with improved stability, involving nontoxic nanocarriers, increase the by means pulmonary administration. Initially, group contribution method was used...

A novel Ni-Fe bimetal with high dechlorination activity for 4-chlorophenol (4-CP) was prepared by ball milling (BM) in this study. Increasing Ni content and time greatly enhanced the activity, which mainly attributed to homogeneous distribution of nanoparticles (50-100 nm) bulk Fe visualized scanning electron microscopy/energy dispersive X-ray spectrometry (SEM/EDS) image mapping. In comparison a chemical solution deposition (CSD) process, milled possessed stability before being used up....

Zirconia ceramic foams with ultra‐high porosity of 96%–98% have been fabricated using sodium dodecyl sulfate ( SDS ) as the particle stabilizer zirconia particles for first time. The wet stabilized by are ultra‐stable due to partially hydrophobic modified . exhibit close cells thin cell wall and small grain size. Increasing concentration favors foamability suspension, further increases foams. 98.1% compressive strength 0.26 ± 0.05 MPa. Decreasing solid loading leads could be improved...

A simple and effective one-step method is proposed for the fabrication of hollow periodic mesoporous organosilica spheres (HPMOSs). The obtained HPMOSs possess well-defined spherical morphology, uniform tunable particle size, adjustable void structure, radially oriented mesochannels in their shells.

Recent developments in the fabrication of hollow spheres have allowed our group to prepare a new type macroporous ceramics: sphere ceramics ( HSC s). Alumina were first produced by centrifugal spray‐drying particle‐stabilized foam slurry. The obtained sintered together form at high temperatures. effect sintering temperature on linear shrinkage, porosity and compressive strength samples was investigated. When increased from 1400°C 1600°C, shrunk increasingly decreased 59% 42%, which lead an...

In this study, we developed a lipid-coated hollow calcium phosphate (LCP) nanoparticle for the combined application of two chemotherapeutic drugs to human lung cancer A549 cells. Hydrophilic doxorubicin (DOX) was incorporated into structure (HCP), and lipid bilayer containing hydrophobic paclitaxel (PTX) subsequently coated on surface HCP. The study combinational effects demonstrated that combination DOX PTX at mass ratio 12:1 showed synergistic effect against particle size, zeta potential,...

Ultralight Si 3 N 4 ceramic foams have been successfully prepared through particle‐stabilized method, which is based on the adsorption of in situ hydrophobized particles to liquid/air interface foams. Here, we firstly used a long‐chain surfactant cetyltrimethylammonium chloride render partially hydrophobic. By tailoring concentration and pH values suspensions, wet were stabilized avoid coarsening coalescence. SEM results show that possess single strut walls with elongated β‐Si grains...

Biological soil crusts are important components of dryland ecosystems, showing variations in appearance, morphology, and function across developmental stages. However, the methods for recording biocrust stages have not been simplified standardized. In this study, three grades both cyanobacterial crust moss were defined based on visual indicators such as color, thickness, height. A field survey was conducted precipitation regions northern China, during which visually recorded. Key indicators,...

Direct coagulation casting of alumina suspension via controlled release high valence counter ions ( DCC – HVCI ) using calcium citrate as coagulating agent was reported. Hydrolysis glycerol diacetate shifts the pH to weakly acidic region which helps decompose and ions. The effect concentration on viscosity investigated at 25°C 60°C, respectively. suspensions with decreases 8.6 7.5 treated It is indicated that achieved by adding 2 vol% 0.5 wt% enough coagulate suspension. Green body...

Porous Si3N4 ceramics were prepared by aqueous gelcasting using poly-hollow microspheres (PHMs) as pore-forming agent. The effects of solid loading slurry and PHM content on the properties porous investigated. Only β-Si3N4 phase is observed in ceramics, PHMs distribute uniformly both green samples ceramics. Results show that could considerably influence With increase (decrease content), distributing state changes from contacting with each other to just embedding matrix, thus their porosity...

Alumina green bodies were prepared by direct coagulation casting via increasing high valence counter ions ( DCC ‐ HVCI ) method. Influence of calcium iodate concentration, temperature, and the solid loading on compressive strength coagulated was investigated. The results show that wet‐coagulated display higher than dried ones. wet is above 2.0 MPa which about one order method, whereas in range 1.0 MPa. body shows elastic deformation, exhibits typical brittle failure behavior. mechanism...

Mechanical instabilities of periodic soft nanostructures and their interaction with the deformation a base could lead to collective buckling. Our theoretical calculations suggest multiple modes buckling associated distinctive potential energies. This discovery allowed us selectively promote certain through experiments as an unusual approach for nanolithography. One typical example includes reducing feature size in buckled grating from pitch 200 130 nm.
