In the title compound, C(10)H(8)ClNO(3), the molecular conformation is stabilized by two intra-molecular hydrogen bonds. The first is a short O-H⋯O hydrogen bond within the maleamic acid unit and the second is a C-H⋯O hydrogen bond which connects the amide group with the phenyl ring. The maleamic acid unit is essentially planar, with an r.m.s. deviation of 0.044 Å, and makes a dihedral angle of...

Τhis study focuses on the exploitation of food-industry wastes as a source for hydrogen production. The wastes which were used were out of date solid baby foods at seven different flavors (solid wastes) and a glucose-based syrup (liquid waste). Preliminary batch hydrogen experiments at mesophilic conditions and initial carbohydrates concentration of 5 g/L were performed to assess the hydrogen p...

BACKGROUND Hydrogen sulphide is a gas signalling molecule which is produced endogenously from L-cysteine via the enzymes cystathionine beta-synthase (CBS) and cystathionine gamma-lyase (CSE). The possible role of hydrogen sulphide in reproduction has not yet been fully investigated. It has been previously demonstrated that hydrogen sulphide relaxes uterine smooth muscle in vitro. The aim of the...

The stringent COx-free hydrogen requirement for the current low temperature fuel cells has motivated the development of COx-free hydrogen production alternatives to the conventional hydrogen production technologies. Recently, our group has investigated step-wise reforming of hydrocarbons and catalytic decomposition of ammonia for COx-free production of hydrogen. These investigations have employ...

Coal and biomass are abundant in supply but contain carbon which, to avoid greenhouse gas emissions, needs to be sequestered after the primary energy conversion. A comparison is reported here of the performance of four different coals and biomass in an iron oxide-based direct chemical looping combustion system. The principal aim is to identify the coal and biomass with the highest H2 to CO2 rat...

-Putrefactive hydrogen sulfide production in the upper 4 cm of sediment in two small freshwater and eutrophic Southeast Michigan, U.S.A., lakes ranged from 0.13 to 1.51 with an average of 0.46 mg S l-~ day-~. Sulfate reductive production of hydrogen sulfide at the same sites ranged from 0.7 to 3.2 with an average of 1.54 mg S 1~ dayt. Putrefactive hydrogen sulfide production represented 5.1-53°...

Oxygen free radicals, including hydrogen peroxide, may mediate oxidative stress in target organ tissues and contribute to cardiovascular complications in hypertension. To examine heritability of hydrogen peroxide production, we investigated this trait in a family-based cohort consisting of family members (n=236) ascertained through probands (n=57) with essential hypertension. Significant effect...

Great attention has been paid to the increasing amount of municipal sludge generated from wastewater treatment plants due to its potential risks to the surrounding environment. The municipal sludge, which mainly composed of polysaccharides, proteins as well as abundant groups of microorganisms, has been proved to be a promising biological material for hydrogen production by anaerobic fermentati...
