Carbon dioxide (CO2) hydrogenation to value-added molecules is an attractive way reduce CO2 emission via upgrading. Herein, non-thermal plasma (NTP) activated over Ru/MgAl layered double hydroxide (LDH) catalysts was performed. The catalysis under the NTP conditions enabled significantly higher conversions (∼85 %) and CH4 yield (∼84 at relatively low temperatures compared with conventional thermally catalysis. Regarding catalyst preparation, it found that reduction temperature can affect...
For large segmental bone defects, porous titanium scaffolds have some advantages, however, they lack electrical activity which hinders their further use. In this study, a barium titanate (BaTiO3) piezoelectric ceramic was used to modify the surface of Ti6Al4V scaffold (pTi), characterized by scanning electron microscopy, energy dispersive spectroscopy, X-ray photoelectron and roughness water contact angle analyses. Low intensity pulsed ultrasound (LIPUS) applied in vitro vivo study. The...
ZSM-5 zeolite nanoboxes with accessible meso-micro-pore architecture and strong acid sites are important in relevant heterogeneous catalysis suffering from mass transfer limitations weak acidities. Rational design of parent zeolites concentrated non-protective coordination Al species can facilitate post-synthetic treatment to produce mesoporous nanoboxes. In this work, a simple effective method was developed convert MFI tetrahedral extra-framework into Al-enriched low silicon-to-aluminium...
Plasma-catalysis systems are complex and require further understanding to advance the technology. Herein, CO poisoning in CO2 hydrogenation over supported ruthenium (Ru) catalysts a nonthermal plasma (NTP)-catalysis system was investigated by combined kinetic diffuse reflectance infrared Fourier transform spectroscopy–mass spectrometry (DRIFTS–MS) study compared with thermal catalytic system. The relevant findings suggest coexistence of Langmuir–Hinshelwood Eley–Rideal mechanisms...

Bone defect repair at load-bearing sites is a challenging clinical problem for orthopedists. Defect reconstruction with implants the most common treatment; however, it requires implant to have good mechanical properties and capacity promote bone formation. In recent years, piezoelectric effect, in which electrical activity can be generated due deformation, of native bone, promotes formation, has been increasingly valued. Therefore, effects also attracted great attention from this study, we...
Developing bioactive materials for bone implants to enhance healing and growth has years been the focus of clinical research. Barium titanate (BT) is an electroactive material that can generate electrical signals in response applied mechanical forces. In this study, a BT piezoelectric ceramic coating was synthesized on surface TC4 titanium alloy, forming BT/TC4 material, low-intensity pulsed ultrasound (LIPUS) then as stimulus. The combined effects biological responses MC3T3-E1 cells were...
