Wetting transitions of liquid hydrogen films
Calculations are presented of the wetting properties of liquid hydrogen films on various substrates. The well depth D for the adsorption potential is even smaller for alkali metal substrates than for noble gas surfaces. A simple model calculation leads to the prediction that wetting transitions should then occur at a temperature T(w) about 20 K. Quartz microbalance data obtained for H-2 on Rb are consistent with this result. Specifically, T(w) is found to be 17.89 +/- 0.04 K. The wetting phase diagram is found to be in good agreement with thermodynamic expectations

Molecular engineering of copolymers with donor-acceptor structure for bulk heterojunction photovoltaic cells toward high photovoltaic performance
A series of donor-acceptor (D-A) conjugated copolymers with benzo[1,2-b:4,5-b-]dithiophene (BDT) as donor and two different electron-accepting groups bithiophenevinyl-2-pyran-4-ylidenemalononitrile (TVM) and benzothiadiazole (BT) moieties as acceptors is designed and synthesized. The optical and electrochemical properties show that the band gaps of the copolymers are in the range of 1.70-1.84 eV, and the HOMO and LUMO energy levels can be tuned effectively by controlling the varied ratios between TVM and BT because of the change of the ICT interaction between donor and acceptor, the electron delocalization degree, and the electron cloud density distribution of the copolymers. Bulk heterojunction photovoltaic devices are fabricated by using the copolymers as donors and (6,6)-phenyl-C61-butyric acid methyl ester (PC61BM) or (6,6)-phenyl-C71-butyric acid methyl ester (PC71BM) as acceptors. The optimized photovoltaic performances show that the open-circuit voltage (Voc) was gradually increased from 0.7 to 0.94 V when decreasing the HOMO energy levels of copolymers, and the short-circuit current density (Jsc) is greatly improved by increasing the absorption spectrum in the visible region, increasing the hole mobility and optimizing the morphologies of blend films between copolymers and PCBM. The optimized photovoltaic performance with a Voc of 0.78 V, J sc of 5.47 mA/cm2, fill factor (FF) of 0.40, and power conversion efficiency (PCE) of 1.67% under simulated AM 1.5 solar irradiation of 100 mW/cm2 is obtained by the copolymer PM50 (PM50:PC 61BM, 1:3 w/w, in CB solution). This is due to its high hole mobility and interpenetrating network morphology of PM50:PC61BM blend film. The photovoltaic device based on PM50:PC71BM shows a Jsc of 8.32 mA/cm2 and a PCE of 2.89%
The Impacts of Lymph on the Adipogenesis of Adipose-Derived Stem Cells
Background: The pathophysiology of adipose proliferation or differentiation in extremity lymphedema has not been thoroughly studied. This study investigated the impacts of the lymph harvested from lymphedematous limbs on the adipogenesis of adipose-derived stem cells (ASCs). Methods: ASCs were isolated from the adipose tissue of normal extremities and cultured with lymph collected from Cheng lymphedema grade III to IV patients or adipogenic differentiation medium (ADM) and further subjected to differentiation and proliferation assay. The expression of adipogenesis genes was examined by real-time polymerase chain reaction to investigate the effect of lymph on ASCs. The level of adipogenic cytokines in the lymph was also evaluated. Results: The adipocytes were significantly larger in lymphedema fat tissue compared with that in normal fat tissues (P < 0.00). The adipogenesis of ASCs cultured in lymph was significantly enhanced compared with in ADM (P = 0.008) on day 10, suggesting that the adipogenesis of ASCs was promoted under the lymph-cultured environment. The expression of adipogenesis genes, peroxisome proliferator-activated receptor (P = 0.02), CAAT/enhancer-binding protein α (P = 0.008); fatty-acid binding protein (P = 0.004), and lipoprotein lipase (P = 0.003), was statistically elevated when the ASCs were cultured with lymph. The insulin content in lymph was statistically higher in lymph (P < 0.001) than in plasma. Conclusions: The adipogenesis of ASCs was promoted under the lymph-cultured environment with statistically increased adipogenesis genes of peroxisome proliferator-activated receptor, CAAT/enhancer-binding protein α, fatty-acid binding protein, and lipoprotein lipase. The excess lymph accumulated in the lymphedematous extremity contained a greater insulin/insulin-like growth factor-2. These adipogenic factors promoted the expression of early adipogenesis genes and led ASCs to undergo adipogenesis and differentiated into adipocytes. Clinical Relevance Statement: The accumulation of adipose tissue in the lymphedema region was contributed from the content of excess lymph

Characterization of the complete chloroplast genome of Carya hunanensis W. C. Cheng & R. H. Chang
Carya hunanensis W. C. Cheng & R. H. Chang is a tree of great economic importance in China. In this study, the complete chloroplast genome of C. hunanensis was determined and analyzed phylogenetically. The whole genome was determined to be 159,892 bp in length, presenting a typical quadripartite structure with a large single copy (LSC) region (89,466 bp), a small single copy (SSC) region (18,714 bp), and a pair of inverted repeat (IR) regions (25,856 bp each). There were 132 genes annotated in the genome, including 84 protein-coding genes, 40 tRNA genes, and eight rRNA genes. The overall GC content of C. hunanensis chloroplast genome was 36.24%. Phylogenetic analysis indicated that C. hunanensis was closely related to C. kweichowensis and Annamocarya sinensis
