Research in the miniaturization of planar chromatography led to various approaches in manufacturing ultrathin-layer chromatography (UTLC) layers of reduced thickness (<50 µm) along with smaller instrumentation, as targeted in Office Chromatography. This novel concept merges 3D print &amp; media technologies with miniaturized planar chromatography to realize an all-in-one instrument, in which al...

Proper motor function requires the precise matching of motoneuron and muscle fiber properties. The lack of distinguishing markers for early motoneurons has made it difficult to determine whether this matching is established by selective innervation during development or later via motoneuron-muscle fiber interactions. To examine whether chick motoneurons selectively innervate regions of their ta...

All-optical signal processing is the focus of much research aiming to obtain effective alternatives to existing data transmission platforms. Amplification of light in fiber optics, such as in Erbium-doped fiber amplifiers, is especially important for efficient signal transmission. However, the complex fabrication methods involving high-temperature processes performed in a highly pure environmen...

The use of reactive dyes has increased rapidly due to outstanding properties, growing consumption of cellulosic fibers, and decrease in the production of other application classes of dyes for cellulosics because of cost and health hazards. However, reactive dyes cause the greatest effluent problems for the dye industry. This study explored reusing these dyes in which the residual dyeings were d...

In Bangladesh, there are thousands of textile-dying industries spread across the country’s many regions, majority which involve knitting and dying. The dyeing industry uses an enormous quantity water, as well colors chemicals. After dying process has been completed, they also release a significant amount wastewater. Cotton, wool, polyester fiber typically dyed with textile dyes such reactive, a...

The extraction and separation of dyes present on textile fibers offers the possibility of enhanced discrimination between forensic trace fiber evidence. An automated liquid sample handling workstation was programmed to deliver varying solvent combinations to acid-dyed nylon samples, and the resulting extracts were analyzed by an ultraviolet/visible microplate reader to evaluate extraction effic...

Organic dyes commonly used for planar laser-induced fluorescence (PLIF) are susceptible to photobleaching under laser excitation. Previous work has shown that photobleaching can induce significant errors in laser-induced fluorescence measurements made with single-point techniques. This paper presents an analytical model and experimental results that quantify the extent of photobleaching in the ...

The discrepancy between the structural longitudinal organization of the parallel-fiber system in the cerebellar cortex and the functional mosaic-like organization of the cortex has provoked controversial theories about the flow of information in the cerebellum. We address this issue by characterizing the spatiotemporal organization of neuronal activity in the cerebellar cortex by using optical ...

The paper presents our new results about efficiency of wastes based on hydrolyzed polyacrylonitrile textile fibers (HPAN) as sorbents in removal of some dyes from textile effluents. The effect of some experimental variables such as initial dye concentration, sorbent mass, pH, temperature, and contact time were investigated. The sorbent dye sorption systems are described using Freundlich, Langmu...

Luminescence-based sensing schemes for oxygen have experienced a fast growth and are in the process of replacing the Clark electrode in many fields. Unlike electrodes, sensing is not limited to point measurements via fiber optic microsensors, but includes additional features such as planar sensing, imaging, and intracellular assays using nanosized sensor particles. In this essay, I review and d...
