-
(American Physical Society, 1993)Multifragmentation, following the formation of toroidal and bubble nuclei, is observed with an improved Boltzmann-Uehling-Uhlenbeck model for central Mo-92 + Mo-92 collisions. With a stiff equation of state, simultaneous ...
-
(2021-07-08)In this study, thymine dimers were detected, for the first time, in both thymine and DNA aqueous solutions using Raman spectroscopy. Thymine dimers, formed by UV radiation of DNA, inactivate bacteria by inhibiting their ...

(2020-06-12)The formation and evolution of Mesozoic-age oceanic lithosphere documents the processes leading to the modern distribution of continents and ocean basins starting with the breakup of Pangaea, and plays an important role ...
-
(2023-07-11)In February of 2021, a series of winter storms moved across the southern continental United States, resulting in extreme cold temperatures on land and in coastal waters. The Texas Automated Buoy System (TABS) network ...
-
(2019-05-22)In this study, research has been conducted to investigate the formation and impacts of aerosols in the atmosphere. Experimental studies were performed to elucidate the role of organic functionality in the nucleation and ...

(Texas A&M University. Libraries, 1977)The reaction of phenyllithium-pyridine intermediate, 1-lithio-2-phenyl-1,2-dihyropyridine, with pentacarbonyliron gave an anionic pyridinylcarbonyl iron complex. Although the isolation of the complex was unsuccessful, the ...
-
(Texas A&M University. Libraries, 1991)Over La2O3 and the transition metal oxide catalysts LiNiO2 and NaMnO4/MgO it was demonstrated that the coupling of the surface-generated gas-phase Ch4 radicals constitutes a major pathway for the formation of C2+ hydrocarbons ...
-
(Texas A&M University. Libraries, 1977)Chelate formation and amide deprotonation reactions of 1:1 cobaltous complexes of glycyl-L-histidine, glycylhistamine, glycyl-L-aspartic acid, L-histidyl-L-histidine, L-histidylglycine, and L-aspartylglycine have been ...
-
(2019-11-19)Matrix acidizing is an effective stimulation technique for carbonate reservoirs and it has been practiced for years in the industry. By injecting acid below the formation fracturing pressure, highly permeable paths called ...
-
(2009-05-15)Constructing and maintaining a formation is critical in applications of cooperative control of multi-agent systems. In this research we address the formation control problem of generating a formation for a group of ...
-
(2012-10-25)Carbon dioxide (CO2) sequestration is defined as the removal of gas that would be emitted into the atmosphere and its subsequent storage in a safe, sound place. CO2 sequestration in underground formations is currently being ...
-
(2013-07-11)Iron precipitation during matrix acidizing treatments is a well-known problem. During matrix acidizing, successful iron control can be critical to the success of the treatment. Extensive literature review highlighted that ...
-
(2012-02-14)Iron control during acidizing plays a key role in the success of matrix treatment. Ferric ion precipitates in the formation once the acid is spent and the pH exceeds 1-2. Precipitation of iron (III) within the formation ...
-
(2016-05-09)Formation damage due to iron precipitation continues to be a major problem in the oil field. Research has established that as the pH of injected acid increases, iron (III) ions start to precipitate and block the pores in ...
-
(2020-12-07)Viscoelastic surfactants (VES) have been successfully applied in well stimulation treatments, including acid-diversion and hydraulic fracturing. However, high temperature, interactions of VES with metallic cations, ...
-
(Texas A&M University, 2003)Formation damage has long been recognized as a potential source of reduced productivity and injectivity in both horizontal and vertical wells. From the moment that the pay zone is being drilled until the well is put on ...
-
(Texas A&M University, 2000)Tests were conducted to evaluate the effect of lubricants in formation damage. Two types of lubricants were tested along with two types of drill-in fluids. The DIF's tested included a sized-calcium carbonate (SCC) and a ...
