TL;DR: In this article, the optimal pore size of nanoporous carbon electrodes is discussed in terms of the maximal stored energy density. But, the authors focus on the choice of the optimal size of the pore and not on the effect of size dispersion.
Abstract: This paper focuses on the choice of the optimal pore size and the effect of pore size dispersion, which is important for the rational design of nanoporous supercapacitors. Optimization of the pore size of nanoporous carbon electrodes is discussed in terms of the maximal stored energy density. By applying a previously developed theory, and supporting it by newly performed experiments, we find that the energy density is a non-monotonic function of the pore size of monodisperse porous electrodes. The ‘optimal’ pore size that provides the maximal energy density increases with increasing operating voltage and saturates at high voltages. We also analyse how the pore size distribution affects the voltage dependent capacitance and the stored energy density, and show that the latter is maximized for monodisperse electrodes.

TL;DR: Nanoimmunity by design can help to design materials for immune modulation, either stimulating or suppressing the immune response, which would find applications in the context of vaccine development for SARS-CoV-2 or in counteracting the cytokine storm, respectively.
Abstract: The COVID-19 outbreak has fueled a global demand for effective diagnosis and treatment as well as mitigation of the spread of infection, all through large-scale approaches such as specific alternative antiviral methods and classical disinfection protocols. Based on an abundance of engineered materials identifiable by their useful physicochemical properties through versatile chemical functionalization, nanotechnology offers a number of approaches to cope with this emergency. Here, through a multidisciplinary Perspective encompassing diverse fields such as virology, biology, medicine, engineering, chemistry, materials science, and computational science, we outline how nanotechnology-based strategies can support the fight against COVID-19, as well as infectious diseases in general, including future pandemics. Considering what we know so far about the life cycle of the virus, we envision key steps where nanotechnology could counter the disease. First, nanoparticles (NPs) can offer alternative methods to classical disinfection protocols used in healthcare settings, thanks to their intrinsic antipathogenic properties and/or their ability to inactivate viruses, bacteria, fungi, or yeasts either photothermally or via photocatalysis-induced reactive oxygen species (ROS) generation. Nanotechnology tools to inactivate SARS-CoV-2 in patients could also be explored. In this case, nanomaterials could be used to deliver drugs to the pulmonary system to inhibit interaction between angiotensin-converting enzyme 2 (ACE2) receptors and viral S protein. Moreover, the concept of "nanoimmunity by design" can help us to design materials for immune modulation, either stimulating or suppressing the immune response, which would find applications in the context of vaccine development for SARS-CoV-2 or in counteracting the cytokine storm, respectively. In addition to disease prevention and therapeutic potential, nanotechnology has important roles in diagnostics, with potential to support the development of simple, fast, and cost-effective nanotechnology-based assays to monitor the presence of SARS-CoV-2 and related biomarkers. In summary, nanotechnology is critical in counteracting COVID-19 and will be vital when preparing for future pandemics.

TL;DR: The use of ribosomal RNA as a probe for molecular epidemiology of bacterial pathogens demonstrates that this method is a widely applicable system for determining the molecular Epidemiology of genetically diverse gram-negative organisms.
Abstract: We investigated the use of ribosomal RNA (rRNA) as a probe for molecular epidemiology of bacterial pathogens. The chromosomal DNA of Escherichia coli, Pseudomonas cepacia, and nontypable Haemophilus influenzae was digested with EcoRI. Agarose gel electrophoresis, Southern blotting, and hybridization by 32P-labeled rRNA revealed eight to 13 bands. The P. cepacia and H. influenzae banding patterns, observed by using an E. coli rRNA probe, were identical to those produced with homologous rRNA probes. Polymorphism of several hybridization bands distinguished all E. coli isolates, nine of 10 H. influenzae isolates, and seven of eight P. cepacia isolates. Two to four bands were common to all P. cepacia and E. coli isolates. The banding patterns of H. influenzae isolates cultured from the trachea and blood of an infant and from the mother's cervix were identical. These data demonstrate that this method is a widely applicable system for determining the molecular epidemiology of genetically diverse gram-negative organisms.

TL;DR: In this article, the role of price and customer satisfaction at different stages on customers' intention to return was investigated in the e-retail industry and the findings indicated that after-delivery satisfaction has a much stronger influence on both overall customer satisfaction and overall satisfaction.
Abstract: Purpose – Compared with the emphasis that service quality research has received in online marketing, much less work has been done on the role of price perception, service attribute‐level performance and satisfaction that unfolds over time, and their effects on customer retention. This paper seeks to fill this gap in the literature.Design/methodology/approach – This paper builds propositions about the role of price and customer satisfaction at different stages on customers' intention to return. Research hypotheses are developed based on theory from the combined literatures of services, product pricing, and behavioral decision theory. Data from the e‐retailing industry related to two specific periods of shopping experience (at checkout and after delivery) are used in the empirical tests. Structural equation modeling is employed to test the hypothesized relationships.Findings – The findings of this study indicate that after‐delivery satisfaction has a much stronger influence on both overall customer satisfac...
