As compared to only AM or DADMAC grafted onto PVP, grafted copolymer with highest DADMAC-to-AM ratio was found to be more effective in removing colloids from fresh unaltered cane juice. The mode of action of the synthesized flocculant was explained by synergistic bridging and charge neutralization...

of measured bonding strengths with four repeats. Full size image The occurrence of lignin self-crosslinking could be confirmed with the increased presence of C–C linkages in hot-pressed lignins, which was implied by decreased monomer yields and increased molecular weights of the resultant products...
Reaction condition: as mentioned in Table 1, Entry 1; ‡ K3PO4 was used instead of KHCO3. Full size image Furthermore, the potential utility of this synthetic strategy was also exemplified by varying the structure of alkenes (Fig. 2). In fact, 1,1-diarylethylenes bearing EWG (4a, 75...
Full size image The magnetic hysteresis loop readings for γ-Fe2O3-MgO@Ch.F., γ-Fe2O3-MgO @Ch.CN and γ-Fe2O3-MgO are 19, 20, and 25 emu·g−1, respectively, indicating saturation magnetization. The observed decrease in saturation magnetization (MS value) may be attributed to th...
The full catalytic reaction cycles can be completed energetically, and N-C60 fullerene recovers to its original structure for the next catalytic reaction cycle. N-C60 fullerene is a potential cathode catalyst for hydrogen fuel cells. 展开
The underlying chemistry in forming a PU foam is quite intriguing. The “one-shot” reaction to form PU foam consists of a liquid polyol, isocyanate and water along with additives such as chain extenders, surfactant, catalysts and others [1]. The formation of urethanes involves reaction between...
In addition to synthetic and semisynthetic compounds, natural products have received much attention as prolific sources of lead compounds with therapeutic effects on various diseases. In the process of screening the bioactivities of potential candidates,
Full size table In addition to plastic waste, various liquid chlorine-containing hydrocarbon wastes were evaluated as chlorination reagents (Table1). Chlorinated solvents and reagents are extensively used in chemistry and for cleaning purposes in many industries8,9,58. For example, dichloromethane (DCM...
Full size image Figure 5d compares the FEs (right) at 2.7 and 3.2 V vs. RHE of LaAlO3/FTO and the onset potential to attain 2 mA cm−2 (left) with previously reported metal oxide catalysts on FTO in the same electrolyte (4 M K2CO3/KHCO3). The LaAlO3 perovskite oxide ...
