Optimal Concentration of Light in Turbid Materials [PDF]
, 2010 In turbid materials it is impossible to concentrate light into a focus with conventional optics. Recently it has been shown that the intensity on a dyed probe inside a turbid material can be enhanced by spatially shaping the wave front of light before it enters a turbid medium.

Turbidity Control in Sedimentation Columns by Direction Dependent Models [PDF]
arXiv, 2023 Sedimentation is a crucial phenomenon in recovering water from slurries by separating solid-liquid. Thickeners and sedimentation columns are equipments widely used in the process industry to reclaim water from process slurries. This contribution addresses the problem of controlling the turbidity of the recovered water in a sedimentation column by ...

Artificial Receptor in Synthetic Cells Performs Transmembrane Activation of Proteolysis
Advanced Biology, EarlyView.Transmembrane signaling is the hallmark of living cells and is among the highest challenges for the design of synthetic cells. Herein, an artificial receptor based on the chemistry of self‐immolative linkers is used to communicate information across the lipid bilayer, for transmembrane activation of enzymatic activity. Abstract The design of artificial,

How Asian slum emissions impact local microclimates in polluted air masses
Atmospheric Science Letters, Volume 23, Issue 12, December 2022., 2022 Cook stove emissions over urban sprawl in South India and expected microphysical implications. Combustion‐mediated soot and black carbon from biomass burning in shantytowns modulate the local cloud cover. Abstract Urban sprawl comprising densely populated slums over South Asian cities yields copious amounts of soot and black carbon from archaic cooking

Event-Driven Imaging in Turbid Media: A Confluence of Optoelectronics and Neuromorphic Computation [PDF]
arXiv, 2023 In this paper a new optical-computational method is introduced to unveil images of targets whose visibility is severely obscured by light scattering in dense, turbid media. The targets of interest are taken to be dynamic in that their optical properties are time-varying whether stationary in space or moving.

The turbidity parameters in Athens [PDF]
Archiv für Meteorologie, Geophysik und Bioklimatologie Serie B, 1976 In this paper Angstrom's turbidity coefficient β0, wave-length exponent α0 and the decadic turbidity coefficientB after Schuepp have been computed in Athens from pyrheliometric measurements of direct solar radiation for the whole spectrum and of specified spectral regions using Schott filters for the period 1963–1972.

Tunable Thermoshrinkable Hydrogels for 4D Fabrication of Cell‐Seeded Channels
Advanced Functional Materials, EarlyView.A thermoresponsive polymer with methacrylate groups for photo‐cross‐linking, based on polyethylene glycol, N‐isopropylacrylamide, and 2‐hydroxyethyl acrylate is synthetized to yield hydrogels that shrink upon temperature increase. The new polymer enables the fabrication of cell‐laden perfusable channels with diameters below 200 µm by combining ...

Self-stratifying turbidity currents [PDF]
arXiv, 2022 Turbidity currents, seafloor flows driven by the excess density of suspended particles, are key conveyors of sediment, nutrient, and pollutant from the continental margins to deep ocean, and pose critical submarine geohazard risks. Due to their vast scale and extreme aspect ratio, extant models are constrained to highly simplified depth-averaged theory
