designed, successfully synthesized, and fabricated into resistive random‐access memory devices (RRAM). The urea‐based molecule showed binary write‐once‐read‐many (WORM) storage behavior, whereas the thiourea‐based molecule demonstrated ternary storage behavior. Atomic‐force microscopy (AFM) and X‐ray diffraction (XRD) patterns show that both molecules have smooth morphology and ordered layer‐by‐layer

A new series of diaryl urea derivatives bearing N-acylhydrazone moiety were designed and synthesized. All the target compounds were evaluated for their antiproliferative activities against human leukemia cell line (HL-60), human lung adenocarcinoma epithelial cell line (A549) and human breast cancer cell line (MDA-MB-231) in vitro by standard MTT assay. The pharmacological results indicated that some compounds exhibited promising antitumor activities. Compound 1j showed the most potent antiproliferative activity against the tested three cell lines with IC50 values of 0.13 mu mol/L, 0.7 mu mol/L and 0.5 mu mol/L, respectively. (C) 2012 Ping Gong.
