A Morphological Study Of Nanomaterials And Biomolecules Using Atomic Force Microscopy, Ravi A. Patel

Ravi A Patel

Understanding the morphologies of molecules and particles has played a key role in understanding key concepts such as mechanisms of formation, interaction and application. In the current work, atomic force microscopy (AFM) techniques are used to emphasize the importance of topography in the field of nanomaterials and biochemistry. The intriguing relationship between graphene oxide and the copolymer Pluronic F-127 is investigated for its potential use in biological applications. Additionally, the importance of characterizing and calculating size distributions in semiconducting quantum dots as it relates to conduction efficiency is also described. AFM is similarly used in determining binding characteristics of two …

Fluorescence-Guided Optical Coherence Tomography Imaging For Colon Cancer Screening: A Preliminary Mouse Study., Arun K. Iyer

Arun Iyer

A new concept for cancer screening has been preliminarily investigated. A cancer targeting agent loaded with a near-infrared (NIR) dye was topically applied on the tissue to highlight cancer-suspect locations and guide optical coherence tomography (OCT) imaging, which was used to further investigate tissue morphology at the micron scale. A pilot study on ApcMin mice has been performed to preliminarily test this new cancer screening approach. As a cancer-targeting agent, poly(epsilon-caprolactone) microparticles (PCLMPs), labeled with a NIR dye and functionalized with an RGD (argenine-glycine-aspartic acid) peptide, were used. This agent recognizes the α(ν)β(3) integrin receptor (ABIR), which is over-expressed by …

Hydrogen Production From Biogas By Oxy-Reforming: Reaction System Analysis, Aleksandra Terlecka, Wojciech M. Budzianowski

Wojciech Budzianowski

Oxy-reforming is emerging as an interesting alternative to conventional methods of hydrogen generation. The current article characterises this process through analysis of individual reactions: SMR (steam methane reforming), WGS (water gas shift) and CPO (catalytic partial oxidation). Analyses relate to optimisation of thermal conditions thus enabling cost-effectivenes of the process.

Ch 21. 'Future Perspectives On Solar Fuels', Thomas A. Faunce

Thomas A Faunce

This chapter opens by examining whether the research and development of molecular solar fuels will be characterized in future by its promotion of fundamental societal virtues such as equality and environmental sustainability. As a thought experiment, it presents a vision of some important elements of such a future world—one where energy is primarily not only a matter of global artificial photosynthesis (GAP), but of such virtues. Central to the future perspective presented here is nanotechnological construction with enhanced efficiency of each aspect of the natural photosynthetic process into units capable of inexpensive mass production for domestic use. This involves a …

Governing Planetary Nanomedicine: Environmental Sustainability And A Unesco Universal Declaration On The Bioethics And Human Rights Of Natural And Artificial Photosynthesis (Global Solar Fuels And Foods)., Thomas A. Faunce

Thomas A Faunce

Environmental and public health-focused sciences are increasingly characterised as constituting an emerging discipline—planetary medicine. From a governance perspective, the ethical components of that discipline may usefully be viewed as bestowing upon our ailing natural environment the symbolic moral status of a patient. Such components emphasise, for example, the origins and content of professional and social virtues and related ethical principles needed to promote global governance systems and policies that reduce ecological stresses and pathologies derived from human overpopulation, selfishness and greed— such as pollution, loss of biodiversity, deforestation and greenhouse gas emissions, as well as provide necessary energy, water and …

Challenges To Australia’S National Health Policy From Trade And Investment Agreements, Thomas A. Faunce

Thomas A Faunce

Recent federal trade policy commitments concerning the Trans-Pacific Partnership Agreement (TPPA) negotiations (against changes to the Pharmaceutical Benefits Scheme (PBS) and against inclusion of an investor state provision) could protect Australia’s tobacco control legislation and Australia's sovereign capacity to regulate public health and environmental policy

The Proposed Ban On Certain Nanomaterials For Electrical And Electronic Equipment In Europe: Global Security Implications, Thomas A. Faunce, Hitoshi Nasu

Thomas A Faunce

International collaboration on nanotechnology governance has so far paid little attention to security implications of regulating the use of nanotechnology. For example, the Coalition of Non-Governmental Organizations (initiated by the International Centre for Technological Assessment) developed 'Principles for the Oversight of Nanotechnologies and Nanomaterials' to provide a set of ethical standards for nanotechnology research and development (Kimbrell, 2009). Similar initiatives are observed at the national level, as has been seen in the Swiss Retailers Association Code of Conduct and the UK's Responsible NanoCode (Bowman and Hodge, 2009, pp.149-152). The Organization for Economic Co-operation and Development (OECD) has also been active …

Selective Recognition Of H2po4 By A Cholestane-Imidazole-Zinc Ensemble, Jyoti Ramesh Jadhav, Md Wasi Ahmad, Hong Seok Kim

Dr. Mohammad Wasi Ahmad (Md Wasi Ahmad)

A new facile amphiphile cholestane-based zinc complex 4 containing a 3-aminopropylimidazole moiety at the 3a and 7a positions of cholestane was designed and synthesized. Recognition selectivity of the new receptor 4 with various anions was assessed by 1H NMR titration. Dihydrogen phosphate showed the highest binding affinity among all the tested anions

Fluorescein-Polyethyleneimine Coated Gadolinium Oxide Nanoparticles As T1 Magnetic Resonance Imaging (Mri)–Cell Labeling (Cl) Dual Agents, Wenlong Xu, Ja Young Park, Krishna Kattel, Md Wasi Ahmad, Badrul Alam Bony, Woo Choul Heo, Seonguk Jin, Jang Woo Park, Yongmin Chang, Tae Jeong Kim, Ji Ae Park, Ji Yeon Do, Kwon Seok Chae, Gang Ho Lee

Dr. Mohammad Wasi Ahmad (Md Wasi Ahmad)

We report the synthesis, characterization and application of highly water-soluble fluoresceinpolyethyleneimine (PEI) coated gadolinium oxide (Gd2O3) nanoparticles to magnetic resonance imaging (MRI) and cell labeling (CL). The average particle diameter and average hydrodynamic diameter were estimated to be 3.92 and 7.5 nm, respectively. Fluorescein-PEI was prepared from EDC/NHS coupling method. The surface coating was characterized by the FT-IR absorption spectrum and the surface coating amount was estimated to be 22.42 wt% from a TGA analysis, corresponding to 0.65 nm22 grafting density. The fluorescein-PEI coated gadolinium oxide nanoparticles showed r1 and r2 of 6.76 and 20.27 s21mM21, respectively, and a strong …

Parallel Text Immersion, Daniel P. Becker Ph.D.

Daniel P. Becker

A new method of teaching foreign languages to beginning, intermediate, and advancing foreign language students is proposed involving reading out loud passages, chapters, and entire works of literature that are familiar to the student through required pre-reading in the students’ mother tongue. Testing is proposed to evaluate the success of the method.

Enhancement In The Photocatalytic Activity Of Au@Tio2 Nanocomposites By Pretreatment Of Tio2 With Uv Light, Mohammad Mansoob Khan Dr, M. H. Cho Dr

Dr. Mohammad Mansoob Khan

A novel, efficient and controlled protocol for the synthesis and enhanced photocatalytic activity of Au@TiO2 nanocomposite is developed. TiO2 (P25) was pretreated by employing UV light (λ = 254 nm) and the pretreated TiO2 was uniformly decorated by gold nanoparticles (AuNPs) in presence of sodium citrate and UV light. UV pretreatment makes the TiO2 activated, as electrons were accumulated within the TiO2 in the conduction band. These accumulated electrons facilitate the formation of AuNPs which were of very small size (2-5 nm), similar morphology and uniformly deposited at TiO2 surface. It leads to formation of stable and crystalline Au@TiO2 nanocomposites. …
