Mechanism Study of the Cross-Linking Reaction
The mechanism of the cross-linking reaction between hydrolyzed polyacrylamide (HPAM) and chromium acetate in formation water was systematically studied by viscometry, ultraviolet-visual absorption spectrometry, and core flow experiments. The results show that the process and outcome of the cross-linking reaction between HPAM and chromium acetate is significantly affected by salinity.

Methylphenidate (MPH) is widely used in the treatment of Attention Deficit Hyperactivity Disorder. Several lines of evidence support that MPH can modulate learning and memory processes in different ways including improvement and impairment of test performances. A relevant factor in the efficacy of treatment is whether administration is performed once or several times.
Intensive research efforts have been pursued to remove arsenic (As) contamination from water with an intention to provide potable water to millions of people living in different countries. Recent studies have revealed that iron-based adsorbents, which are non-toxic, low cost, and easily accessible in large quantiti
Pancreatic cancer: a mechanobiology approach - IOPscience
For many years, research in the field of pancreatic cancer focused on targeting cancer cells, but during the last decade the PDAC tumour microenvironment has attracted significant attention. PDAC is characterised by an extensive desmoplastic reaction or fibrosis that surrounds the tumour comprising up to 90% of the total tumour mass [ 3 ].
Chelating agents, because of their metal specificity, can function as effective mineral processing reagents. A brief review of the work carried out in this area is presented. Some of the salient features of mineral flotation and flocculation with chelating-type reagents, such as bulk vs. surface chelation, the role of pH, mineral solubility, solution chemistry of reagents, and temperature, are

These nanocomposites were utilized for aqueous Cr(VI) elimination via solgel technique with no additional crosslinking agent. The proposed mechanism of this process is illustrated in Figure 18. The maximal adsorption capacity (69.8 mg/g) was reached at pH 5.0 and 200C. Cr (VI)-loaded NIOC could be effectively regenerated by alkaline solutions.
Invasive and contractile properties of cancer cells can be correlated in vitro using invadopodia and traction force assays based on polyacrylamide gels (PAAs) of different rigidities. While some variations between the two assays exist, the protocol presented here provides a method for creating PAAs that can be used in both assays and are easily
