Abstract Background Identification of protein complexes is crucial for understanding principles cellular organization and functions. As the size protein-protein interaction set increases, a general trend to represent interactions as network develop effective algorithms detect significant in such networks. Results Based on study known networks, this paper proposes new topological structure complexes, which combination subgraph diameter (or average vertex distance) density. Following approach...

Semicarbazide (SEM) is a widespread carcinogenic and neurotoxic food contaminant, originating from the metabolite of antibiotic nitrofurazone, which used in aquaculture, or thermal decomposition byproduct flour blowing agent azodicarbonamide. Although optical detection technologies are powerful tools considering advantages fast response visualization detection, there few nanosensors for highly sensitive visual assays SEM due to no luminescence UV absorbance SEM. Herein, an upconversion...

Mesna is an important regional antidote for protecting the urinary system of chemotherapy patients, which requires monitoring its level in real time to ensure curative effect. The fluorescence method a powerful tool real-time detection with advantages fast response and visualization. However, background interference limits application biological sensing. Here, we developed portable sensing platform using upconversion-based nanosensor visual quantitative mesna real-time/on-site conditions....

Effects of various factors on zeta potential air bubbles in aqueous solution were studied. It was found that the water pH, surfactants types and concentration, temperature had significant roles bubbles. Increase pH caused a great decrease (more negative) The concentration not only affecting intensity but also determining nature bubble surface charges. In addition, have an obvious effect

Rationally design of highly efficient and stable electrocatalysts for alkaline hydrogen evolution reaction (HER) toward anion exchange membrane water electrolyzer (AEMWE) is urgently needed but remains quite challenging. Herein, we...

Premature seal failure induced by the unevenness of interstage pressure distribution in multi-stage brush seals significantly compromises sealing efficiency Air-Turbo Rocket (ATR) engines operating under high-pressure (megapascal-level) differential conditions. Conventional equalization designs for such often result significant leakage rate increases. This study addresses imbalance phenomenon four-tooth three-stage composite through a novel fractal–geometric porous-media model, rigorously...

When using the water‐based extraction processes (WBEPs) to recover bitumen from weathered oil sands, very low recovery arisen poor liberation of sand grains is always obtained. Application microbial enhanced (MEOR) technology in WBEPs solve processability ore was proposed. It found that microbial‐treated greatly improved. The improved attributed biosurfactants production culture solution, alteration solids wettability, degradation asphaltene component, and decrease viscosity, which...

Water-assisted solvent extraction processes (WASEPs) were developed by introducing a water layer between the oil sands and to extract bitumen from sands. The condition was well investigated using naphtha as solvent. Considering cost, advised for industrial application conducted under stirring at temperature of 50–60 °C 30 min ratio in 1:1:0.5 (wt/wt/wt). At such conditions, recovery about 72–74% obtained on processing weathered ore. In case some types ore, surfactant needs be added aqueous...

Bright and efficient white-polymeric light-emitting diodes (WPLED) were fabricated using poly(2-(2'-ethylhexyloxy)-5-methoxy-1,4- phenylenevinylene) (MEH-PPV) doped in poly(fluorene) (PF) with an architecture of ITO/PEDOT/MEH-PPV : PF(0.6 wt%)/Ba/Al. At low doping levels, blue emission from PF yellow MEH-PPV co-existed photoluminescence (PL) spectra, because incomplete energy transfer the to MEH-PPV. When weight ratio is set at 0.6%, device exhibits stable white electroluminescence (EL) CIE...

Through an optimized synthetic strategy, a series of novel alkylpyridinium cobalt tetracarbonyl salts, [C(1)Py][Co(CO)(4)] (), [C(4)Py][Co(CO)(4)] () and [C(16)Py][Co(CO)(4)] (C(n)Py = N-C(n)H(2n+1)-pyridinium), were successfully prepared in good yields, using water-organic biphasic system. All the three compounds melt well below 100 degrees C could be classified as ionic liquids.
