Developing conducting polymer nanocomposites with carbon nanomaterials for molecular detection and fuel cell applications
No full textConducting polymers are attractive for chemical sensors because their conductivity and electrochemical activity is extremely sensitive to molecular interactions. The inherent specificity of the conducting polymer based sensors stems from the fact that only certain chemicals can trigger a dramatic conductance change. It can be made more specific by further chemical functionalization of the polymer. The use of conducting polymers (CPs) as low-cost electrocatalysts was also investigated in the early history of conducting polymer research and applications. However, their low environmental stability, low conductivity, and electrochemical activity limit their practical industrial applications. Inspired by the remarkable electronic and superior mechanical properties of carbon nanomaterials, especially carbon nanotubes (CNTs) and the relatively new material graphene, tremendous efforts have been made over the past decade to fabricate conducting polymer and CNT composites with an aim of synergistically combining the merits of each individual components. In this thesis, a series of novel conducting polymer nanocomposites with these remarkable carbon nanomaterials will be designed and developed with an ultimate goal of sensitive and selective detection of warfare agents for homeland security and low-cost metal free electrocatalysts for fuel cell applications. Experimental results demonstrate that the composite shows dramatically improved performance compared to each of the individual components. The results obtained from these studies combined with an introduction of the state of the art of the development in this field and future prospects will be presented through 6 chapters of this thesis.Ph.

Here we identify Nupr1 as a mechanosensitive protein involved in the regulation of tumor cell plasticity and Sox2 expression. We monitored Nupr1 and Sox2 expression over time in cells cultured in soft 3D fibrin matrices. Using both untreated and Nupr1-siRNA treated cells, we find that high Nupr1 expression prevents increase in Sox2 levels. Further, we find that Nupr1 expression is sensitive to substrate stiffness and dependent on ligand type, as Nupr1 expression increased with substrate stiffness on polyacrylamide substrates coated with col-1 but not fibrinogen. Finally, we find that Nupr1 is sensitive to stiffness in 3D culture as well, and is downstream of Cdc42-mediated cytoskeletal softening. Together, our data shows that Nupr1 responds to the physical properties of its surroundings and can regulate tumor cell plasticity via delay of Sox2 expression in 3D.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2017-08-01The student, Rishi Singh, accepted the attached license on 2015-07-21 at 15:33.The student, Rishi Singh, submitted this Thesis for approval on 2015-07-21 at 15:37.This Thesis was approved for publication on 2015-07-22 at 08:44.DSpace SAF Submission Ingestion Package generated from Vireo submission #8542 on 2015-09-29 at 15:06:3
In vivo and In vitro Estimation of Colchicine in Gloriosa superba L. by High Pressure Liquid Chromatography
No full textThe presence of Colchicine in Gloriosa superba was confirmed by Thin Layer Chromatography (TLC) and High Pressure Liquid Chromatography (HPLC) in which a spot coinciding with the authentic sample of Cochicine in Rf value (Colchicine 0.70) appeared. The maximum amount of Colchicine was found in flower (20.7 mg/gdw) and minimum amount was found in stem (7.4 mg/gdw).The In vitro studies showed the maximum amount of Colchicine in 6 week old cultures (22.6 mg/gdw)) and minimum amount in 2 weeks old cultures (15.3 mg/gdw).

Characterizing material properties of cement-stabilized rammed earth to construct sustainable insulated walls
No full textAbstractUse of local materials can reduce the hauling of construction materials over long distances, thus reducing the greenhouse gas emissions associated with transporting such materials. Use of locally available soils (earth) for construction of walls has been used in many parts of the world. Owing to the thermal mass of these walls and the potential to have insulation embedded in the wall section has brought this construction material/technology at the forefront in recent years. However, the mechanical properties of the rammed earth and the parameters required for design of steel reinforced walls are not fully understood. In this paper, the author presents a case study where full-scale walls were constructed using rammed earth to understand the effect of two different types of shear detailing on the structural performance of the walls. The mechanical properties of the material essential for design such as compressive strength of the material including effect of coring on the strength, pull out strength of different rebar diameters, flexural performance and out-of-plane bending on walls was studied. These results are presented in this case study
Unlearning The Basics: _A New Way of Understanding Yourself and the World_
No full textUNLEARNING THE BASICS is a non-sectarian philosophical introduction to Buddhist thought and practice. The fundamentals of Buddhadharma are explored in their original contexts and in conversation with both psychoanalytic developmental theory and existential-phenomenological thought on finitude and ‘authentic’ ways of living. That being said, this is not a book ‘for scholar’s only’. Its writing is accessible to any educated persons with an interest in the subject.
⮕ MU SOENG (review)
“An exciting read. Sativihari's book is in many ways a model for how the teachings of the
Buddha could and should be talked about in a psychologically mature and sophisticated
environment and offers his own innovative insights into what the Buddha was trying to
convey in his explication of the four noble truths. This is an important book and I hope it
gets the wide audience it deserves. It adds much to the current discourses and also brings
us much closer to a more nuanced understanding of the Buddha's own thought processes.”

"An exhilarating and lucid introduction to Buddhist thought. Sativihari begins with a
sophisticated reading of the Four Noble Truths as a sacred poem and ends with a plea for
more compassionate culture and politics. In between there is wisdom spiked on every page.”

⮕ GILLES MONGEAU (review)
“As a practitioner trained in Christian forms of meditation, I am deeply grateful for Rishi
Sativihari's achievement in ‘Unlearning The Basics.’ His translation of Buddhist wisdom into
Western language and images is practical and concrete. Often, attempts to help Westerners
understand Buddhism rely too heavily on idealist philosophies, leading to a kind of
mystification of the four noble truths. Because Dr. Sativihari appeals consistently to
experience and is sophisticated in his understanding of Western philosophy and theology,
he can present the four noble truths with profound spiritual realism. The work is very
reader-friendly, showing the fruits of extensive reflection on pedagogical practice.
There is genuine spiritual maturity at work in this text.”
