Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A novel Pd (0) nanoparticles anchored over cyano modified SBA-15 was synthesized and characterized with different physicochemical techniques like Transmission Electron Microscopy (TEM), Field Emission Scanning Electron Microscopy (FESEM), Energy Dispersive X-ray Spectroscopy (EDX), N 2 adsorption-desorption isotherm, X-ray elemental mapping and X-ray Photoelectron Spectroscopy (XPS). Pd content on the catalyst surface was determined to be 0.12 mmol/g by induced coupled plasma atomic emission spectroscopy (ICP-AES). The composite surface material was described as a novel heterogeneous nanocatalyst for the ligand-free C–C bond formation using Suzuki-Miyaura coupling at room temperature in air without the use of inert atmosphere. It afforded excellent yields in short reaction time. The catalyst was recovered and recycled 12 times without a significant loss of catalytic activity. To survey the cytotoxicity and anti-human lung cancer properties of catalyst, MTT assay was used on the common human lung cancer cell lines i.e., moderately differentiated adenocarcinoma of lung (LC-2/ad), poorly differentiated adenocarcinoma of lung (PC-14), and well-differentiated bronchogenic adenocarcinoma (HLC-1). The catalyst had high anti-human lung cancer and very low cell viability potentials dose-dependently against LC-2/ad, PC-14, and HLC-1 cell lines. The best result of anti-human lung cancer effects was observed in the case of the PC-14 cell line. After approving the above results in the clinical trial studies, catalyst may be used as a chemotherapeutic drug for the treatment of human lung cancer.
