are important in controlling the environmental fate of potentially toxic metals. However, little is known about the effects of LWMAAs on the interactions between biochars and potentially toxic metals. Herein, the influences of three aromatic acids, including benzoic acid (BA), p-hydroxy benzoic...

suppose you wanted to determine the moles of aspirin in a 250 mg aspirin tablet. Typing “aspirin” into the NIST database reveals that the drug’s chemical name is 2-acetyloxy-benzoic acid and its molecular formula is C9H8O4. This indicates that one aspirin molecule contains nine carbon ...
The molecular weight of purified IN was about 33 kDa, with a purity of about 95%. Figure 1. Expression of HIV-1 IN in E coli. Lane 1, cell suspension containing the empty vector of pET28(a) after IPTG induction; 2, cell suspension containing pET-IN before inducement; 3, cell suspen...
As AlbAS can tolerate a shortened building block A (para-hydroxy benzoic acid in compound 2, see Supplementary Figure 14), the steric demand of β-methoxy-l-Asn and its anticipated effect on the backbone conformation in building block C appears to hinder the stabilization of both domains. In...

Changes in the fluorescence of PAAc–EDANS hydrogels by FRET were investigated using aminated 4-(4¢-dimethylaminophenyl azo)- benzoic acid (amino-DABCYL) as a cationic quencher, which was synthesized by coupling DABCYL with ethylenediamine and adsorbed on the anionic polymer network. Because the...
