Carbon dioxide flooding is considered to be one of the most effective enhanced oil recovery methods for the light oil reservoirs. Depending on the operating pressure, the process might be miscible or immiscible. Minimum miscibility pressure (MMP) is the most important parameter for assessing the applicability of any miscible gas flood for an oil reservoir. The miscibility condition is determine...

The measurement of the minimum miscibility pressure (MMP) is one of the most important steps in the project design of miscible gas injection for which several experimental and modeling methods have been proposed. On the other hand, the standard procedure for compositional studies of miscible gas injection process is the regression of EOS to the conventional PVT tests. Moreover, this procedure d...

Spatial Light Interference Microscopy (SLIM) is a novel method developed in our laboratory that provides quantitative phase images of transparent structures with 0.3 nm spatial and 0.03 nm temporal accuracy owing to the white light illumination and its common path interferometric geometry. We exploit these features and demonstrate SLIM's ability to perform topography at a single atomic layer in...

The minimum miscibility pressure (MMP) is one of the crucial and substantial parameters in the gas injection projects for enhanced oil recovery (EOR). This parameter indicates the minimum pressure at constant temperature and composition conditions for reaching 100 percent of the oil production recovery which leads to a huge economic income. Therefore, an inaccurate prediction of the MMP may lea...

The creation of drag-reducing surfaces in deformed tubes is vital importance to thermal management, energy, and environmental applications. However, it remains a great challenge tailor the surface structure wettability inside slim complicated feature. Here, we describe an electrochemical anodization strategy achieve uniform superhydrophobic coating TiO2 nanotube arrays throughout inner deformed...

Site-directed, Ligase-Independent Mutagenesis (SLIM) is a novel PCR-mediated mutagenesis approach that can accommodate all three sequence modification types (insertion, deletion and substitution). The method utilizes an inverse PCR amplification of the template by two tailed long primers and two short primers in a single reaction with all steps carried out in one tube. The tailed primers are de...

A postlarva of Nanaloricidae (Loricifera) was found in the deep sea of the Guinea Basin. This postlarva belongs to a new species, Culexiregiloricus trichiscalida, which also represents a new genus. It inhabits clayish sediments with a high amount of calcitic multi-chambered shells of recent planktonic foraminiferans of 0.25 to 1.5 mm in size. This is the third report of a species of Nanaloricid...
