Abstract:

In this manuscript we report a small molecule that can selectively bind to the bacterial lipid phosphatidylethanolamine and consequently functions as an antibacterial agent against certain Gram-positive bacteria.

Abstract:

We report studies toward a small-molecule-catalytic approach to access atropisomeric diaryl ethers that proceeds through a C(sp2)–H alkylation using nitroalkanes as the alkyl source. A quaternary ammonium salt derived from quinine, containing a sterically hindered urea at the C-9 position, was found to effect atroposelective C(sp2)–H alkylation with moderate to good enantioselectivities across several naphthoquinone-containing diaryl ethers. Products could then be isolated in >95:5 er after one round of trituration. For several substrates that were evaluated, we obtained nitroethylated prod

Abstract:

Water-soluble cellulose ethers are widely used as stabilizers, thickeners, and viscosity modifiers in many industries. Understanding rheological behavior of the polymers is of great significance to the effective control of their applications. In this work, a series of cyanoethylcellulose (CEC) samples with different molecular weights were prepared with cellulose and acrylonitrile in NaOH/urea aqueous solution under the homogeneous reaction. The rheological properties of water-soluble CECs as a function of concentration and molecular weight were investigated using shear viscosity and dynamic rh

Various types of hydrogen bonds exist in polyether polyurethane, polyurethane-urea and polyurea (PUA) and can cause microphase separation. The morphology, properties and applications of polyether PUA are determined by the microphase separation. All kinds of hydrogen bonds make it difficult to assignments of Fourier transform infrared spectroscopy (FTIR) peaks of ether linkage, amine and carbonyl group. This affects the calculation of the hydrogen bonding degree of the hard segments for estimating the degree of microphase separation. This paper summarized hydrogen bonding structures between pro

Full-length AGMO could not be expressed in three different E. coli expression strains, three different expression vectors and several induction systems.

Abstract:

Two experiments were conducted to investigate the effects of slow-release urea (SRU) on in vitro rumen fermentation parameters, growth performances, nutrient digestibility, and serum metabolites of beef cattle. The single factor design was applied in both experiments. Three diets with different nitrogen sources including soybean meal (Control group), slow-release urea (SRU group), and common urea (Urea group) was designed (concentrate to forage ratio was 4:6). The diets were formulated to be isoenergetic and isonitrogenous, 75% of the soybean meal in the control diet was replaced by 1.41% SRU

Abstract:

An experiment of treated and ensiled wet rice straw with urea and molasses was performed to explore the chemical composition, physical quality, in vitro digestibility and its potentiality as a quality feed for ruminants. In this experiment, plastic containers were used to preserve chopped wet rice straw under airtight condition based on the treatment as T1 (wet rice straw only), T2 (straw with 5% molasses), T3 (straw with 5% urea), T4 (straw with 5% urea and 5% molasses) and T5 (straw with 10% urea and 5% molasses) to analyze chemical composition, physical quality, metabolizable energy (ME) co
