Removal of trichloroethene from thin clay lenses by electrical resistance heating: Laboratory experiments and the effects of gas saturation

Removal of trichloroethene from thin clay lenses by electrical resistance heating: Laboratory experiments and the effects of gas saturation
The elimination of dissolved risky natural compounds (VOCs) from low-permeability lenses is necessary to restrict again diffusion at websites impacted by dense non-aqueous part liquids (DNAPLs). In situ thermal remedy (ISTT) applied sciences have the potential to deal with DNAPL-impacted websites by enhancing diffusion from low-permeability lenses throughout heating.
A sequence of two-dimensional laboratory tank experiments was carried out to research heating, gasoline formation, and trichloroethene (TCE) elimination from a clay lens surrounded by sand. Outcomes confirmed preferential heating of the clay and substantial TCE elimination, with post-heating relative concentrations lower than 0.06.
The extent of TCE elimination was not defined by solely a rise within the aqueous TCE diffusion coefficient with elevated temperature. Modelling estimates primarily based on 1D diffusion from the lens confirmed that diffusion by way of each gasoline and water phases was required to match observations.
Gasoline formation within the inside of the lens was additionally indicated by measured adjustments in bulk electrical conductivity of the clay throughout quiet down, with gasoline saturations estimated to be better than 0.21 on the finish of heating.
These estimates had been bigger than these wanted to match the noticed elimination by diffusion, and recommend that linked gasoline pathways had been created within the lens throughout heating, however that not all the gasoline produced was a part of these pathways.
These outcomes recommend that ISTT applied sciences could also be efficient in eradicating dissolved VOCs from skinny clay lenses, and that gasoline formation inside the clay needs to be thought of when predicting the extent and fee of elimination.

A technique for learning lipid adsorption to silicone hydrogel contact lenses

The goal of this research was to develop an experimental methodology to measure lipid deposition with contact lenses. Contact lenses had been incubated in a lipid resolution. The quantity and kinds of adsorbed lipids had been assessed utilizing mass spectrometry and confocal microscopy. The restoration of lipids from lenses various with lipid and lens kind.
Most non-polar and polar lipids had been desorbed from lenses throughout the first 5 min of extraction. Fluorescently labelled phosphatidylcholine sure inside the matrix of Senofilcon A lenses however to the floor of Lotrafilcon B lenses, whereas fluorescently labelled cholesteryl ester was discovered all through each lenses.
The efficacy of extraction of lipids from contact lenses varies for various lipid courses and completely different lens supplies. Variations within the quantity and time of lipid desorption in all probability resulted from the energy of the bond between lipid and lens polymer and the depth of adsorption of lipid within the polymer.

Electrically tunable polarization unbiased liquid crystal lenses primarily based on orthogonally anisotropic orientations on adjoining micro-domains

Polarization dependency is an intrinsic property of liquid crystals (LC) gadgets however main drawback is optical effectivity. We demonstrated a polarization unbiased liquid crystal part modulation primarily based on the orthogonal nematic LC (OLC) mode whereby the optics axes of nematic liquid crystal molecules are set orthogonally to adjoining sub-domains for the primary time.
Such an OLC mode contains sub-domain with anisotropic orientations however collectively presents a functionality of a polarizer-free optical part modulation. An OLC mode cell supplies a tunable optical part of ∼3.35π radians for unpolarized gentle and completely different linearly polarized gentle. Among the many polarizer-free LC mode, the proposed OLC mode is single-layered with giant tunable optical part.
We additionally demonstrated a polarizer-free LC micro-lens. We anticipate this novel LC mode present options know-how roadmap for upcoming optical functions, reminiscent of electrically tunable ophthalmic lenses and optical programs for augmented actuality.

Optical nano-imaging through microsphere compound lenses working in non-contact mode

Microsphere lens for nano-imaging has been broadly studied due to its superior resolving energy, real-time imaging attribute, and extensive applicability on various samples. Nevertheless, the additional growth of the microsphere microscope has been restricted by its restricted magnification and small field-of-view.
On this paper, the microsphere compound lenses (MCL) which permit enlarged magnification and field-of-view concurrently in non-contact imaging mode have been demonstrated. A theoretical mannequin involving wave-optics results is established to information the design of MCL for various magnifications and imaging configurations, which is extra exact in contrast with frequent geometric optics concept.
Experimentally, utilizing MCL to picture the specimen with a tunable magnification from 2.8× to 10.3× is realized. Because of the enlarged magnification, a high-resolution goal with 137 nm line width will be resolved by a 10× goal. In addition to, the field-of-view of MCL is bigger than that of a single microsphere and will be additional elevated by way of scanning working method, which has been demonstrated by imaging a pattern with ∼76 nm minimal function measurement in a big space.
Prospectively, the well-designed MCL will develop into irreplaceable parts to enhance the imaging performances of microsphere microscope identical to the compound lens within the typical macroscopic imaging system.

Color compound lenses for a transportable fluorescence microscope.

On this article, we demonstrated a handheld smartphone fluorescence microscope (HSFM) that integrates dual-functional polymer lenses with a smartphone. The HSFM consists of a smartphone, a field-portable illumination supply, and a dual-functional polymer lens that performs each optical imaging and filtering.

Subsequently, in contrast with the prevailing smartphone fluorescence microscope, the HSFM doesn’t want any further optical filters. Though fluorescence imaging has historically performed an indispensable function in biomedical and scientific functions resulting from its excessive specificity and sensitivity for detecting cells, proteins, DNAs/RNAs, and many others., the cumbersome parts of typical fluorescence microscopes make them inconvenient to be used in point-of-care analysis.
The HSFM demonstrated on this article solves this drawback by offering a multifunctional, miniature, small-form-factor fluorescence module. This multifunctional fluorescence module will be seamlessly hooked up to any smartphone digital camera for each bright-field and fluorescence imaging at cellular-scale resolutions with out the usage of further cumbersome lenses/filters; the truth is, the HSFM achieves magnification and light-weight filtration utilizing a single lens.
