Unveiling key impact parameters and mechanistic insights towards activated biochar performance for carbon dioxide reduction.

Chemically activated biochar is effective in supercapacitors and water splitting, but low conductivity hinders its application as a carbon support in carbon dioxide reduction reaction (CORR). Based on the observed CORR performance from potassium hydroxide (KOH)-activated biochar, increased microporosity was hypothesized to enhance the performance, leading to selection of potassium carbonate (KCO) for activation. KCO activation at 600℃ increased microporosity significantly, yielding a total Faradaic efficiency of 72%, compared to 60% with KOH at 800℃.

Revealing the "Yin-Jing" mystery veil of Platycodon grandiflorum by potentiating therapeutic effects and lung-oriented guidance property.

Unlabelled: ETHNIC PHARMACOLOGICAL RELEVANCE: "Yin-Jing" medicine (YJM) has been widely used by both ancient and modern Chinese medicine practitioners during long-term clinical practice. However, it remains unclear how to best guide other medicines to the targeted organs in a traditional Chinese medicine (TCM) prescription. Here, in an attempt to explain the scientific connotation of the YJM property (YJMP) attributed to a basic TCM theory, Platycodon grandiflorum (PG) was chosen as a case study to reveal the mystery of YJMP theory.

Fructooligosaccharides and fructans from Platycodon grandiflorum: Structural characterization, lung-oriented guidance and targetability.

Platycodon grandiflorum (PG) has been widely applied as a conductant drug by ancient and modern traditional Chinese medicine practitioners during long-term clinical practice. However, determining how to guide other medicines to the targeted lungs in traditional Chinese medicine (TCM) prescription remains unclear. An ethanol soluble fraction (Fr.

[Carbon sequestration characteristics and regional differences of typical warm and tropical grasslands in Henan Province, China.].

In this study, we examined the vegetation and soil carbon density characteristics and carbon distribution differences of four typical grasslands in two climatic zones, including warm-tempe-rate tussock (WT), warm-temperate shrub tussock (WS), tropical tussock (TT), and tropical shrub tussock (TS) in Henan Province. The results showed that the average aboveground biomass of grasslands was significantly higher in Northwest Henan (327.4 g·m) than that in South Henan (221.

Stabilization of lead in incineration fly ash by moderate thermal treatment with sodium hydroxide addition.

Municipal solid waste (MSW) incineration fly ash (IFA) can be potentially reused as a substitute for some raw materials, but treatment for detoxification is indispensable owing to high contents of heavy metals in fly ash. In the present work, due to excessive leaching concentration of lead (Pb), a moderate thermal treatment with sodium hydroxide (NaOH) addition was employed to stabilize Pb in IFA. The moderate thermal treatment was performed under relatively low temperature ranging from 300 to 500°C and at retention time from 1 to 3 h with NaOH addition in a range of 1 to 9%.

Effects of pre-pregnancy body mass index and gestational weight gain on neonatal birth weight.

To evaluate the effects of maternal pre-pregnancy body mass index (pre-BMI) and gestational weight gain (GWG) on neonatal birth weight (NBW) in the population of Chinese healthy pregnant women, attempting to guide weight control in pregnancy. A retrospective cohort study of 3772 Chinese women was conducted. The population was stratified by maternal pre-BMI categories as underweight (<18.

Advanced development in phytochemicals analysis of medicine and food dual purposes plants used in China (2011-2014).

In 2011, we wrote a review for summarizing the phytochemical analysis (2006-2010) of medicine and food dual purposes plants used in China (Zhao et al., J. Chromatogr.

Detection of the cell viability and proliferation using two-signal electrochemical method.

Two electrochemical signals of the MCF-7 cell were simultaneously detected by using multiwall carbon nanotubes and room temperature ionic liquid composite film modified electrode. The signal at +0.726 V due to the oxidation of xanthine and guanine, was obviously improved.
