Microwave assisted fabrication of a nanostructured reduced graphene oxide (rGO)/Fe2O3 composite as a promising next generation energy storage material

Abstract: Herein, we report a facile two-step process involving homogenous precipitation followed by microwave assisted reduction to fabricate a rGO–Fe2O3 composite. The applicability of the composite as an electrode material for supercapacitors has been evaluated by a cyclic voltammetry (CV) and galvanostatic charging–discharging (GCD) study. The composite displays excellent supercapacitor performance compared to bare rGO and generates a high specific capacitance of 577.5 F g−1, at a current density of 2 A g−1. A high rate performance is also observed by retaining a specific capacitance of 437.5 F g−1, at a high current density of 10 A g−1. Finally, the electrodes have been analyzed through electrochemical impedance spectroscopy (EIS) to probe the charge transfer characteristics and the results have been found to be consistent with other electrochemical measurements. The remarkable electrochemical performance of the rGO–Fe2O3 composite can be attributed to the positive synergistic effects between rGO platelets and Fe2O3 nanoparticles.

Spectroscopic investigation of interaction between bovine serum albumin and amine-functionalized silicon quantum dots

Abstract: We have investigated the dynamics and mechanistic details of the interaction between bovine serum albumin (BSA) and allylamine-capped silicon quantum dots (Si QDs) by means of fluorescence spectroscopy, circular dichroism (CD), and FTIR spectroscopy. The intrinsic fluorescence of BSA gets quenched in the presence of Si QDs due to ground-state complex formation. The binding stoichiometry and various thermodynamic parameters have been evaluated by using the van't Hoff equation. It has been observed that the association process is driven by a favourable negative enthalpy change with an unfavorable negative entropy change. These results have been explained by considering specific hydrogen bonding interactions between amine moieties (–NH2) of Si QDs and carboxylate groups (–COO−) of aspartate (Asp) and glutamate (Glu) residues of BSA. Circular dichroism (CD) and FTIR spectroscopy revealed nominal changes in the secondary structure of the adsorbed proteins due to partial unfolding of the native protein upon surface adsorption while the overall tertiary structure remains close to that of the native state.

An Overview of Hardware Security and Trust: Threats, Countermeasures, and Design Tools

Abstract: Hardware security and trust have become a pressing issue during the last two decades due to the globalization of the semiconductor supply chain and ubiquitous network connection of computing devices. Computing hardware is now an attractive attack surface for launching powerful cross-layer security attacks, allowing attackers to infer secret information, hijack control flow, compromise system root-of-trust, steal intellectual property (IP), and fool machine learners. On the other hand, security practitioners have been making tremendous efforts in developing protection techniques and design tools to detect hardware vulnerabilities and fortify hardware design against various known hardware attacks. This article presents an overview of hardware security and trust from the perspectives of threats, countermeasures, and design tools. By introducing the most recent advances in hardware security research and developments, we aim to motivate hardware designers and electronic design automation tool developers to consider the new challenges and opportunities of incorporating an additional dimension of security into robust hardware design, testing, and verification.
