MnO/NiO Nanoparticles Decorated on Carbon Nanofibers as an Enzyme-Free Electrochemical Sensor for Glucose Detection.

Transition metal oxides have garnered a lot of attention in the field of electrocatalysis along with their unique crystal structure and excellent catalytic properties. In this study, carbon nanofibers (CNFs) decorated with MnO/NiO nanoparticles were made using electrospinning and calcination. The conductive network constructed by CNFs not only facilitates electron transport, but also provides landing sites for nanoparticles, thus reducing nanoparticle aggregation and exposing more active sites.

Axillary uniportal video-assisted thoracoscopic surgery for bullae is a cosmetically superior approach to primary spontaneous pneumothorax: a case report.

Background: Bulla is a common cause of primary spontaneous pneumothorax. Video-assisted thoracoscopic surgery (VATS) through the lateral chest wall is a common surgical approach and an effective treatment for this condition, but postoperative incision scars affect the aesthetic outcome. VATS via axillary approach can hide the scar in the axilla, and the wound in its natural state is invisible; this greatly improves the cosmetic appearance.

[Spatial variation of carbon density in Pinus massoniana forest in Jiangxi Province, China].

Carbon density is one of the important indicators for carbon sequestration capacity in forest ecosystems. The analysis of spatial variation in forest carbon density can provide scientific basis for management of forest carbon sink. We investigated the carbon density of Pinus massoniana forest in Jiangxi Province.

[Carbon density distribution characteristics and influencing factors in aerially seeded Pinus massoniana plantations].

The distribution characteristics of carbon density under aerially seeded Pinus massoniana plantations in Ganzhou City of Jiangxi Province were studied. Total 15 factors, including site, stand, understory vegetation, litter and so on were selected to establish a relationship model between stand carbon density and influencing factors, and the main influencing factors were also screened. The results showed that the average carbon density was 98.

[Study on the optimal extraction process of polysaccharide from Baphicacanthus cuaia (Nees) Bremek with the uniform design].

Objective: To study the optimal extraction process of polysaccharide from Baphicacanthus cuaia (Nees) Bremek.

Methods: The optimal extraction process was selected with uniform design and statistical analysis system (SAS). The content of polysaccharide in the extract was determined to investigate the influence of temperature of extraction, the time of extraction and the solid-liquid ratio on it.
