Previous experimental work has shown that microcapsule walls, made by solidification of a molten wax, are unexpectedly permeable. The hypothesis was that this was due more to the structure of the wall than the material itself.

Cuticular wax is the main transpiration barrier against uncontrolled water loss for all aerial plant organs. This study presents water permeability and chemical composition of the cuticle on the petal...
While hydraulic fracturing technology, aka fracking (or fraccing, frac), has become highly developed and astonishingly successful, a consistent formulation of the associated fracture mechanics that wo...
Racemic and highly enantioenriched 3-methoxycarbonyl, 3-carboxy and 3-hydroxymethyl derivatives of dibenzohelicene were prepared. The Langmuir layers of these helicenes were formed at the air-water...
Thin film composite (TFC) polyamide membranes set the golden standard for reverse osmosis technology, but tuning their permeability and selectivity remains a major challenge because of the inherent pe...
Assessing physical stability of drugs is important both in the development as well as in the production phase in the pharmaceutical industry. We used nanomechanical infrared (NAM-IR) spectroscopy base...
Natural killer T (NKT) cells are a unique subset of lymphocytes that present a mixed T-NK phenotype. Our hypothesis is that Natural killer T cells may decrease the tumor burden and improve...
In this double blind, crossover study participants will consume a cranberry beverage and a cranberry-flavored beverage for 2 weeks each. Gut permeability will be assessed weekly using aspi...
In rodents, obesity is associated with changes in tight junctions' structure in small intestine, which impacts intestinal permeability and results in metabolic complications. Few data exis...
In this double blind, crossover study participants will take a placebo for 3 weeks each. Gut permeability will be assessed weekly using food-grade sugar molecules. On the second week, part...
Increased intestinal permeability is one of the main pathophysiological mechanisms involved in irritable bowel syndrome. The expression of some intestinal tight junction proteins is decrea...
A mass of organic or inorganic solid fragmented material, or the solid fragment itself, that comes from the weathering of rock and is carried by, suspended in, or dropped by air, water, or ice. It refers also to a mass that is accumulated by any other natural agent and that forms in layers on the earth's surface, such as sand, gravel, silt, mud, fill, or loess.

The thin serous membrane enveloping the lungs (LUNG) and lining the THORACIC CAVITY. Pleura consist of two layers, the inner visceral pleura lying next to the pulmonary parenchyma and the outer parietal pleura. Between the two layers is the PLEURAL CAVITY which contains a thin film of liquid.
A mixture of several dental waxes, usually containing paraffin wax, ceresin, beeswax, resins, and other natural and synthetic waxes. It is used for making patterns to determine the shape of the metallic framework and other parts of removable partial dentures. (From Jablonski's Dictionary of Dentistry, 1992, p868)
The use of a quartz crystal microbalance for measuring weights and forces in the micro- to nanogram range. It is used to study the chemical and mechanical properties of thin layers, such as polymer coatings and lipid membranes; and interactions between molecues.
Chromatography on thin layers of adsorbents rather than in columns. The adsorbent can be alumina, silica gel, silicates, charcoals, or cellulose. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)
