Engineering strategy of yeast metabolism for higher alcohol production

open access: yesMicrobial Cell Factories, 2011
Background While Saccharomyces cerevisiae is a promising host for cost-effective biorefinary processes due to its tolerance to various stresses during fermentation, the metabolically engineered S. cerevisiae strains exhibited rather limited production of

Utilisation de produits organiques oxygénés comme carburants et combustibles dans les moteurs. Deuxième partie : Les différentes filières d'obtention des carburols. Analyse technico-économique Using Oxygenated Organic Products As Fuels in Engines. Part Two: Different Systems for Producing Alcohol Fuels. Technico-Economic Analysis

open access: yesOil & Gas Science and Technology, 2006
Parmi les produits à même d'être substitués aux hydrocarbures pour la constitution des carburants, les composés organiques oxygénés occupent une place prépondérante à cause de leurs caractéristiques favorables à la combustion dans les moteurs, qu'ils ...

A Simplified Method for Butanol-Extractable Iodine and Butanol-Insoluble Iodine

open access: yesClinical Chemistry, 1966
Abstract A simplified method is presented for the determination of butanol-extractable iodine(BEI). The results compare favorably with the original method as described by Man et al. Also available, as part of the procedure for BEI, is a direct chemical determination for butanol-insoluble iodine (Bll) from the same specimen of serum ...

Ligand‐Mediated Shape Engineering of SWIR InAs Colloidal Quantum Dots for Photodetector Applications

open access: yesAdvanced Materials, EarlyView.
The table of contents: A robust ligand‐engineering strategy is introduced for SWIR InAs CQDs synthesized from amino‐arsine precursors. Bulky OA ligands induce controlled shape evolution, allowing access to >1700 nm absorption under mild conditions. Halide‐based inkification enables photodetectors with 19.1% EQE at 1300 nm and detectivity exceeding 1010

Intrinsically Stretchable Piezoelectric Nanocomposites for Artificial Ultrasonic Sensory Synapse

open access: yesAdvanced Materials, EarlyView.
Applying ultrasonic stimulations to a soft‐stretchable underwater piezoelectric sensor based on the soft‐stretchable nanocomposite from the thermal cross‐linking between the ─C─F group of P(VDF‐TrFE) and the ─NH2 group of (PEG‐diamine) with incorporating amine‐terminated BTO@APTES nanofillers on the soft PDMS substrates generated high piezoelectric ...

Hydrophobic MFI‐Type Zeolites via Alkali‐Cation‐Induced Defect Healing: Implications for Adsorbent and Catalyst Design

open access: yesAdvanced Materials, EarlyView.
Sub‐stoichiometric amounts of Na+ or K+ enhance defect healing during Silicalite‐1 (MFI) and TS‐1 calcination by promoting Si–O–Si annealing and healing framework vacancies. The resulting defect‐free zeolites are more hydrophobic and show improved butanol/water separation and improved activity and selectivity in the epoxidation of 1‐hexene, offering a ...

PRMT1‐Mediated LDHA Methylation Drives STAT3 Lactylation to Orchestrate Intestinal Inflammation and Tumorigenesis

open access: yesAdvanced Science, EarlyView.
This study identifies an immunometabolic axis wherein SAM‐driven PRMT1 methylates LDHA, enhancing its activity. The resultant lactate induces STAT3 K709 lactylation, which stabilizes an active conformation to promote STAT3 phosphorylation and IL‐10 expression.
