Defluoridation of Water Using Silica Based Aluminum Coated Adsorbents
… ions except bicarbonate. All sorbents followed pseudo-second-order kinetics and fit Langmuir and Freundlich isotherm models, indicating favorable adsorption. Sorbent regeneration and reuse were investigated through re-coating techniques using the original coating solutions. The re-coated …

Non-thermal Recovery of Heavy oil and Oil Sands Using Nanoparticle
… oil from these reservoirs because of their low efficiency and negative effects on the environment, particularly with respect to oil sands; there is room to improve efficiency and using new methods. A more efficient method that improves the recovery from heavy oil reservoirs with a smaller …

Chemistry in a new key: Surplus, soy, and the history of sustainable enterprise in the United States, 1934-1950
… calls that processes of industrial production be low-waste, renewable, even “green.” The tensions internal to this modernist doctrine of scientific praxis, which anchored innovation firmly in the soil, situate a North American genealogy of the logics by which today’s industries of sustainable …

ANALYSIS BY CAPILLARY ELECTROPHORESIS WITH LASER-INDUCED FLUORESCENCE DETECTION: FROM SMALL MOLECULES TO WHOLE CELLS
… include minimal solvent and sample requirements, low waste volumes, simple instrumentation, and diversity of analytes studied. CE is one of the most efficient separation techniques available for the analysis of both large and small molecules, but because few analytes are natively fluorescent, it …

Sustainable strategies for alcohol halogenation
… towards halogenation, with respect to halide waste generation. Though many organocatalytic routes to alcohol halogenation have been developed, these methods often require the use of polyhalogenated starting materials, generating a super-stoichiometric amount of halogenated waste. Reported …

Miniaturised analytical systems with chemiluminescence detection for environmental applications
… a method of measuring hydrogen peroxide in the low micromolar concentrations was achieved, producing a limit of detection of 4.7 nmol L⁻¹ with a small sample volume (10 μL min⁻¹). A small reagent consumption size (1.2 mL per hour) and a low waste production size (2.4 mL per hour) were also …
