2018Co-Authors: Harish K Krishnamurthy, Sheldon Weng, George E Matthew, Krishnan Ravichandran, James W Tschanz, Vaibhav Vaidya, Pavan Kumar, Rinkle Jain, Nachiket Desai, Vivek DeAbstract:A fully integrated digitally controlled two-phase buck voltage regulator (VR) with on-die solenoid inductors with a planar Magnetic Core is demonstrated in 14-nm tri-gate CMOS for fine-grained power delivery/management domains of high power density in system-on-chips while enabling ultra-thin (z-height) packages. The VR achieves 1-A/mm2 power density for 400-mA load current with a measured peak efficiency of 84% at 100-MHz switching frequency including a digital PWM with >9 bits (8 ps) of resolution.

Magnetic Core shell structured and surface molecularly imprinted polymers for the rapid and selective recognition of salicylic acid from aqueous solutions
2018Co-Authors: Zulei Zhang, Jianlin Shi, Dechao NiuAbstract:Abstract In this work, a novel kind of Magnetic, Core-shell structured and surface molecularly imprinted polymers (MMIPs) for the recognition of salicylic acid (SA) was facilely synthesized through a surface imprinting and sol-gel polymerization approach. The as-synthesized MMIPs exhibit uniform Core-shell structure and favorable Magnetic properties with a saturation magnetization of 22.8 emu g −1 . The binding experiments demonstrated that MMIPs possessed high binding and specific recognition capacity, as well as fast binding kinetics and phase separation rate. The maximum binding capacity of MMIPs is around 36.8 mg g −1 , nearly 6 times that of the Magnetic non-imprinted polymers (MNIPs). Moreover, the selectivity experiments show that all the relative selectivity coefficients towards SA over its structure analogs are higher than 18, further indicating the markedly enhanced binding selectivity of MMIPs. Furthermore, the MMIPs were successfully applied for the determination of SA in environmental water samples with the recovery rates ranging from 94.0 to 108.0 %. This strategy may provide a versatile approach for the fabrication of well-defined molecularly imprinted polymers on nanomaterials for the analysis of complicated matrixes.

au capped Magnetic Core mesoporous silica shell nanoparticles for combined photothermo chemo therapy and multimodal imaging
2012Co-Authors: Hangrong Chen, Yu Chen, Xia Wang, Feng Chen, Xiangzhi Cui, Jianlin ShiAbstract:Uniform Au NRs-capped Magnetic Core/mesoporous silica shell nanoellipsoids (Au NRs-MMSNEs) were prepared by coating a uniform layer of Au NRs on the outer surface of a Magnetic Core/mesoporous silica shell nanostructure, based on a two-step chemical self-assembly process. This multifunctional nanocomposite integrate simultaneous chemotherapy, photo-thermotherapy, in vivo MR-, infrared thermal and optical imaging into one single system. The obtained multifunctional nanoellipsoids showed very low cytotoxicity, and the cancer cell uptake and intracellular location of the nanoellipsoids were observed by confocal laser scanning microscopy and bio-TEM. Importantly, the prepared multifunctional nanoellipsoids showed high doxorubicin loading capacity and pH value-responsive release mainly due to the electrostatic interaction between DOX molecules and mesoporous silica surface. Besides, a synergistic effect of combined chemo- and photo-thermo therapy was found at moderate power intensity of NIR irradiation based on the DOX release and the photothermal effect of Au NRs.

fabrication of uniform Magnetic nanocomposite spheres with a Magnetic Core mesoporous silica shell structure
2005Co-Authors: Wenru Zhao, Lingxia Zhang, Hangrong Chen, Jianlin ShiAbstract:A novel kind of Magnetic Core/mesoporous silica shell nanospheres with a uniform particle diameter of ca. 270 nm was synthesized. The inner Magnetic Core endues the whole nanoparticle with Magnetic properties, while the outer mesoporous silica shell shows high enough surface area and pore volume. The synthesized material is expected to be applied to targeted drug delivery and multiphase separation. The storage and release of ibuprofen into and from the pore channels of the mesoporous silica shell, as a typical example, are demonstrated.
