The objective of this research was to evaluate the effect of low concentrations of a rhamnolipid biosurfactant on the in situ biodegradation of hydrocarbon entrapped in a porous matrix. Experiments were performed with sand-packed columns under saturated flow conditions with hexadecane as a model hydrocarbon. Application of biosurfactant concentrations greater than the CMC (the concentration at ...

We describe a general synthesis of conductive gold thin films doped with entrapped organic molecules, and demonstrate, for the first time, the immobilization of a redox couple within an electrode in a single step. The resulting film is of dual properties: conductivity arising from the gold, and redox behavior originating from the entrapped molecule. Faster electron-transfer rates are found for ...

<p class="abstract">Amidst the growing tentacles of coronavirus SARS2 in densely populated Delhi (India), healthcare workers and other essential service providers are working day night to keep city going. All with a fear, fear getting entrapped any moment. Here is personal account myself, worker who got entrapped, thankfully not strangulated, having recovered early without trolled physica...

The knowledge about the solid forms landscape of Bilastine (BL) has been extended. crystal structures two anhydrous have determined, and relative thermodynamic stability among three known polymorphs established. Moreover, chloroform solvates with variable stoichiometry identified characterized, showing that S3CHCl3-H2O SCHCl3 can be classified as transient which transform into new solvate SCHCl...

In the present study, a novel laccase from ascomycete Gliomastix murorum was produced in agro-industrial wastes and entrapped galactomannan beads for Reactive Blue 2 (Rb-2) decolorization. The maximum production agave bagasse-based medium occurred at 72 h (1798.6 UL−1). Entrapped decolorized ˃80% of 0.5 mM Rb-2 without addition redox mediator. Km substrate 1.42 mM, with Vmax 1.19 µmol min−1 lac...

The central venous catheter (CVC) is associated with numerous complications more so during the process of insertion. We report for the first time how an indwelling catheter was entrapped by a replacement catheter on the same side, after being speared by the introducer needle and guidewire. The diagnosis was made when there was difficulty in removing the old catheter. Subsequently, interventiona...

?-Carotene (vitamin A precursor) and ?-tocopherol, the utmost energetic form of vitamin E (VE), are known to be fat-soluble vitamins (FSVs) essential nutrients needed enhance growth metabolic functions human body. Their deficiencies linked numerous chronic disorders. Loading FSVs within nanoemulsions could increase their oxidative stability solubility. In this research, VE (BC) were successfull...

A highly sensitive, fast and stable biosensor for determination of nitrite was developed using hemoglobin immobilized on a poly (N-isopropylacyamide-co-3methacryloxypropyltrimethoxysilane) (PNM) modified glass carbon electrodes. The matrix provided a biocompatible microenvironment for retaining the native structure and activity of the entrapped hemoglobin. Nitrite could be reduced by the electr...

Proton-detection in solid-state NMR, enabled by high magnetic fields (>18 T) and fast magic angle spinning (>50 kHz), allows for the acquisition of traditional (1)H-(15)N experiments on systems that are too big to be observed in solution. Among those, proteins entrapped in a bioinspired silica matrix are an attractive target that is receiving a large share of attention. We demonstrate that (1)H...
