To reduce the lattice oxygen content of Si3N4 green bodies, samples were prepared using an N,N-dimethylacrylamide (DMAA) system. The endothermic and exothermic peaks are related to decomposition organic matter reaction between pyrolytic carbon impurity oxides in sintering process. Multi-step heat preservation during thermal degreasing process reduced defects. α→β phase transformation aspect ratio grains changed from 89.2% 4.84:1 at 1640 °C 96.3% 7.80:1 1700 °C, respectively. relative...

Oral delivery of nanoparticles possesses many advantages for active pharmaceutical ingredients (APIs) to the gastrointestinal tract. However, poor physical stability in liquid state is often a challenge. Removing water from nanosuspensions and transforming into solid particulate matter form of, e.g., tablets could be potential approach increase nanoparticles. The aim this study was transform compacts investigate redispersion as well dissolution behavior these compacts....

The estimation of inhalation flow rate (IFR) using acoustic devices has recently received attention. While existing work often assumes that the microphone is placed at a fixed distance from device, this assumption does not hold in real settings. This leads to poor IFR since energy varies significantly with distance. Despite fact source passive and only one used, we show paper can be estimated by exploiting inhaler actuation sound, generated when releasing medication. Indeed, sound used as...

A new toxin from Xanthomonas retroflexus could cause a series of physiological responses on seedlings redroot pigweed. The experimental results revealed that respiratory ratio first increased 106% after treatment with the CFS (concentrated centrifugal fermentation supernatants) X. for 2 h, and decreased 3 h; peroxidase (POD) activity 30% 50% 1 h respectively; Malon dialdehyde (MDA), soluble protein mitotic indices appeared not to be affected by toxin. Ultrastructure observation indicated...

Plasticizers are essential additives in the processing of polyvinyl chloride (PVC), with phthalate plasticizers being widely used. However, these conventional have been shown to be harmful human health and environmentally unfriendly, necessitating exploration eco-friendly bio-based alternatives. In this study, <i>Camellia oleifera</i> seed oil, a specialty resource China, was utilized as raw material reacted 4,4′-Methylenebis(N,N-diglycidylaniline) (AG-80) synthesize Phenyl Camellia Oil...
