Biochar as a Catalyst

Abstract: Biochar is pyrogenic carbon rich material generated from carbon neutral sources ( i.e. , biomass). Being an environmentally benign means for soil amendment, it also offers principle strategies for carbon capture and storage (CCS). In addition, recent recognition of biochar as versatile media for catalytic applications has brought forth initial research exploring the catalytic capacity of biochar and mechanistic practices in various routes. Thus, to provide comprehensive information on the catalytic applications of biochar in the field of catalysis, this review focuses on the catalytic challenges and practices of biochar, e.g. , biodiesel production, tar reduction in bio-oil and syngas (synthetic gas: H 2 and CO), enhanced syngas production, conversion of biomass into chemicals and biofuels, deNO x reactions, and microbial fuel cell electrodes. This review also provides an in-depth assessment on the catalytic properties of biochar with respect to production recipes at the fundamental level. Lastly, the performance of various biochar catalysts is also evaluated in this review.

C-H activation: a complementary tool in the total synthesis of complex natural products.

Abstract: The recent advent of transition-metal mediated CH activation is revolutionizing the synthetic field and gradually infusing a “CH activation mind-set” in both students and practitioners of organic synthesis. As a powerful testament of this emerging synthetic tool, applications of CH activation in the context of total synthesis of complex natural products are beginning to blossom. Herein, recently completed total syntheses showcasing creative and ingenious incorporation of CH activation as a strategic manoeuver are compared with their “non-CH activation” counterparts, illuminating a new paradigm in strategic synthetic design.

Analyzing Online Information Privacy Concerns: An Information Processing Theory Approach

Abstract: The advent of the Internet has made the transmission of personally identifiable information common and often inadvertent to the user. As a consequence, individuals worry that companies misuse their information. Firms have tried to mitigate this concern in two ways: (1) offering privacy policies regarding the handling and use of personal information, (2) offering benefits such as financial gains or convenience. In this paper, we interpret these actions in the context of the information processing theory of motivation. Information processing theories, in the context of motivated behavior also known as expectancy theories, are built on the premise that people process information about behavior-outcome relationships. We empirically validate predictions that the means to mitigate privacy concerns are associated with positive valences resulting in an increase in motivational score. Further, we investigate these means in trade-off situation, where a firm may only offer partially complete privacy protection and/or some benefits

Ultrasonography and the Ultrasound-Based Management of Thyroid Nodules: Consensus Statement and Recommendations

Abstract: The detection of thyroid nodules has become more common with the widespread use of ultrasonography (US). US is the mainstay for detecting and making the differential diagnosis of thyroid nodules as well as for providing guidance for a biopsy. The Task Force on Thyroid Nodules of the Korean Society of Thyroid Radiology has developed recommendations for the US diagnosis and US-based management of thyroid nodules. The review and recommendations in this report have been based on a comprehensive analysis of the current literature, the results of multicenter studies and from the consensus of experts.
