A study of the reaction of cellulose nitrate with various reducing agents
Cellulose nitrate does not react with diphenyl or diethyl zinc dissolved in toluene, nor does it react with diethyl tin in liquid ammonia solution. In the latter case the cellulose nitrate is converted to cellulose amine by the ammonolytic effect of the ammonia. Powdered sodium borohydride added to …

THE DEVELOPMENT OF ALTERNATIVE STRATEGIES FOR USING CHEMICAL OXIDIZING AND REDUCING AGENTS IN FLOURS AS A MEANS OF CONTROLLING GLUTEN STRENGTH PRIOR TO DEVELOPING DOUGH
… in relation to the control. The effect of a reducing agent (L-cysteine), commonly used in the baking industry was also investigated. The optimization of the production time vs. quality of bread is crucial for the industry. Therefore, reducing agents can be used in stronger wheat cultivars as …

Chemical reduction and oxidation combined with biodegradation for the treatment of a textile dye wastewater
… textile dye wastewater was accomplished using reducing agents. The reducing agents studied were sodium hydrosulfite, thiourea dioxide, and sodium borohydride. Preliminary tests were conducted using just the reducing agents. Although there was color reduction, the reduced wastewater was …

A Mechanistic-Based Approach to Reduce Biological Adhesion
… to defeat adhesion with the incorporation of reducing agents into a variety of coatings to inhibit oxidative chemistry and glue formation. Literature also supports that with lower surface energy coatings, adhesion strength decreases. Therefore, we have investigated what effect lowering the …

FUNCTIONAL STUDIES OF THE FE-S CLUSTER BIOGENESIS BY SUF SYSTEM
… are partially protected from the action of reducing agents such as DTT and glutathione. Under these conditions, the reaction profile shows a biphasic behavior, where the second phase of the reaction is associated with the accumulation of persulfurated/polysulfurated forms of SufE. In B. …

Engineering streptavidin and its target ligands with both infinite binding affinity and reversible binding capability
… Incubation with biotin in the presence of reducing agents allows stripping off tagged proteins from streptavidin.

Factors Affecting the Toxicity and Metabolism of Organic Arsenicals (Roxarsone, Copper, Cysteine)
… arsenicals and compounds which can act as reducing agents. It was concluded that cysteine exacerbates roxarsone toxicity by reducing it to the more toxic trivalent state.

Precursors And Processes For The Growth Of Metallic First Row Transition Metal Films By Atomic Layer Deposition
… lack of suitable metal precursors and powerful reducing co-reagents that can convert precursors in positive oxidation states to the metals. In this dissertation, the development of new transition metal precursors, solution phase reaction screening for powerful reducing agents, and ALD growth of …

Birch reduction of cinnamic acid
<p>The use of alkali and alkaline earth metals as reducing agents in liquid ammonia solvent for aromatic and conjugated systems has been investigated by chemists at least since the early 1900's, e.g., Lebau and Picon (1). By subsequent additions of a proton source, the system yielded the first …

Purification of Global Regulator, Spx, and RNA Polymerase from Staphylococcus aureus for Use in In Vitro Transcription of Redox Genes
… the gene encoding thioredoxin reductase, without reducing agents. RNA polymerase was partially purified from S. aureus, and the enzyme was active, catalyzing transcription of rpsD, but not trxB.

Design and Synthesis of Doxorubicin Conjugated Gold Nanoparticles as Anticancer Drug Delivery System
… of the most widely used and effective anticancer agents to treat a wide spectrum of tumors. But its success in cancer therapy is greatly compromised by its cumulative dose-dependent side effects of cardiotoxicity and tumor cell resistance. For the purpose of addressing these side effects, a gold …

Discovery and Delivery of Bioactive Natural Products
… of native drug can be achieved by the action of reducing agents, and that reductive drug release gave the cleanest drug release.

Characterization of Attachment and Receptor Isolation of Infectious Pancreatic Necrosis Virus to Chse-214 Cells
… the monolayer with various proteolytic enzymes, reducing agents and specific blocking agents. IPNV attached optimally at a pH of 7.2-7.4 within 10 to 15 seconds at 23°c. Treatment of the monolayer with chyrotrypsin and neuraminidase decreased viral attachment at all concentrations tested. …

The design and construction of a novel pipe flow apparatus for exploring polymer drag reduction
… the slimes produced by fishes are effective drag reducing agents per unit weight; the slime of the Pacific Hagfish (Eptatretus stout), in particular, contains both long, flexible fibers and high molecular weight mucin polymer chains.

The importance of the antiperiplanar effect in the nucleophilic addition of hydride to a carbonyl group.
… effects, the study indicates, for all three reducing agents, a series of inconsistent results. The plots of log ($\rm k\sb{R}\sp{app}/k\sb{H}$) and ($\rm k\sb{R}\sp{ac}/k\sb{H}$) versus $\sigma\sb1$ do not exhibit a strong correlation. For all three reducing agents, the data for the methoxy …

Plasmonic hot carrier-driven electrochemistry
… electrons, which are powerful solution phase reducing agents. This fundamental insight reveals the opportunity for new reaction pathways for plasmon-induced reactions by moving the reaction site away from the particle surface.

The Comprehensive Study of High Viscosity Friction Reducers in High-TDS and High-Temperature Environments
… and increasing in use, not only as friction-reducing agents but also as proppant carriers. Reusing of produced water has also been driven by both environmental and economic benefits. Currently, most friction reducers on the market are anionic friction reducers, which are fully compatible with …

Cyclic nitrones: oxidation studies and the synthesis of a heterocyclic nitrone
… with the N-O-C repeating unit. Typical nitrone-reducing agents have been shown to be effective towards the heterocyclic nitrone. Arylhydrazines oxidised the heterocyclic nitrone with cleavage of the ether band, yielding glyoxal osazones. The same nitrone was very rapidly oxidised to …
