Moessbauer study of synthetic hematite aggregates.
2009Synthetic hematite aggregates that result from a process that may have industrial and environmental relevance are studied by Mossbauer spectroscopy at room temperature and liquid nitrogen temperature. The Mossbauer results are compared to measurements involving chemical analysis, scanning electron microscopy, and X-ray diffraction on the same samples ...

Small molecule modulators of aggregation in synthetic melanin polymerizations
Bioorganic & Medicinal Chemistry Letters, 2012There are numerous potential applications for melanin-binding compounds, and new methods are of interest to identify melanin-binding agents. A portion of the polymerization to eumelanin, the black to brown pigment in humans, is thought to be supramolecular aggregation of nanoparticles derived from dihydroxyindoles.

Self-aggregation of synthetic multi-hydroxylated zinc chlorophylls
Tetrahedron, 2010Abstract A series of zinc 3-hydroxymethyl-131-oxo-(bacterio)chlorins possessing additional hydroxy group(s) on the B-ring were synthesized as models of bacteriochlorophylls-c/d/e, self-aggregative light-harvesting pigments of green photosynthetic bacteria.

Thixotropic Changes with Aging of Synthetic Soil Aggregates
Soil Science Society of America Journal, 1970Abstract Artificially prepared aggregates held at constant water content increased in relative stability with time. The increase is analogous to a thixotropic sol‐gel transformation and to an increase in strength of packed soil with aging. Aggregates were not perceptibly stable to wet sieving at time of formation.

Self-Aggregates of Synthetic Bacteriochlorophyll-F Derivatives
1998Bacteriochlorophyll(=BChl)s-c, -d and -e have been found in an extramembranous antenna of green photosynthetic bacteria. Additionally, the structure of the putative BChl-f has been reserved, which has been neither found nor isolated from any natural photosynthetic bacteria yet.

Biochimica et Biophysica Acta (BBA) - General Subjects, 1966
Abstract The change in physical state of biopolymer can be a general method of enhancing its ability to elicit antibody formation. The formation of an electrostatic aggregate between a negatively charged, non-immunogenic synthetic polypeptide and methylated bovine serum albumin renders the molecule immunogenic. Aggregate formation enhances the amount

Aggregate Demand, Aggregate Supply, and Endogenous Growth: A Synthetic neo-Kaleckian Model [PDF]
, 2010 This paper develops a neo-Kaleckian endogenous growth model that incorporates aggregate supply - demand balance and balance between labor force and employment growth. The paper explicitly models income distribution which is a critical channel whereby unemployment affects investment and growth. The model generates a growth unemployment rate trade-off. A

Alkali aggregate reactivity in dense concretes containing synthetic or porous natural aggregate
Cement and Concrete Research, 1989Studies have been made into the relative importance of pore solution dilution, accommodation of gel pressures and potential reactivity of porous aggregate in the suppression of alkali aggregate expansion in concretes containing a pessimum proportion of thames valley sand.

Spruce Beetle Aggregated by the Synthetic Pheromone Frontalin
Canadian Journal of Forest Research, 1973Frontalin, a synthetic attractant developed from the southern pine beetle (Dendroctonusfrontalis Zimm.), induced spruce beetle (D. rufipennis Kirby) attacks on preselected spruce trees destined for harvest, and adjacent trees. If baited trees were treated with insecticide, spruce beetles and predators (Thanasimusundatulus Say) were killed.
