Highly-selective Chemiresistive Sensing and Analysis of Vapors Using Functionalized Nanotubes
… array of nanostructured gas-sensors comprised of selectively, novel surface-functionalized carbon nanotubes (for analyte selectivity by virtue of functionality). Harnessing carbon nanotubes with various electron withdrawing and donating groups help in determining their affinity toward certain …

Underrepresented Students at Highly Selective Universities: Are Institutions Supporting Students’ Aspirations?
Highly selective universities have long played a role as one of the gatekeepers to privileged positions in society. For the last century underrepresented students have been systematically excluded from these institution, resulting in social reproduction (Karabel, 2006; Bastedo & Jaquette, 2011; …

Macroscopic graphene membranes with tunable nanopores for highly selective mass separation
… mechanism to separate water from salts, where selective transport of species arises from their solubility and diffusivity in polymer phase. Despite the remarkable progress in materials, structure, and separation process over the past few decades, today's membranes are subjected to intrinsic …

Preparing the public secondary school student for highly selective college admission
… school students when seeking admission to highly selective colleges. This study has identified the characteristics that distinguish college guidance and school-wide programs at public secondary schools perceived to be the strongest (distinguished) from other public secondary schools. School …

Highly Selective Attentional Modulation of Task-Appropriate Neural Populations in Primary Visual Cortex
… this simple attentional mechanism is in fact highly specific: attentional modulations are only present within task-appropriate neurons or neuron groups, and it is the location (and not nature) of these modulations which defines the observer’s current attentive state. We present the results of …

The preparation and characterisation of highly selective adsorbents for fission product removal from acid solutions
… Pu. This research focuses on the synthesis of highly stable and selective materials which could be used as a stationary phase in a continuous chromatographic separation for short lived fission products (Cs, Sr); a technique patented by UCLan. The objectives of this project were to synthesis …

In Vitro Selection and Characterization of Highly Selective Metal -Dependent DNAzymes With Potential Biosensor Applications
A separate in vitro selection experiment was carried out in the presence of Pb2+ in order to compare the secondary structures of the resulting DNAzymes with the structure of the 8-17-like DNAzymes, which were selected through three independent experiments in the presence of: (1) Zn2+, (2) Mg2+, and …

Discovery of novel highly selective Rho kinase (ROCK) inhibitory peptides and evaluation of their biological activities
… conformation and since the ATP binding site is highly conserved in kinases, these inhibitors can cause many side effects associated with their nonspecific binding and inhibition of other kinases such as PKA and PKC. In order to overcome this poor-selectivity limitation, targeting allosteric …

Parental Influence on Graduate School Aspirations among First Generation and Non-First Generation College Students Attending Highly Selective Institutions
… and non-first generation students attending highly selective institutions. Three dimensions of capital were explored in this study: (a) human, (b) cultural, and (c) social. Additionally, this study was designed to determine whether there are differences in the degree of these forms of capital …

I. In vitro selection of aptamers for perchlorate and melamine II. Towards crystallization of DNAzymes III. A highly selective lead sensor based on a classic lead DNAzyme
… Based on the GR-5 DNAzyme, a much more selective and slightly more sensitive sensor for Pb2+ has been developed.

The Locus of Preparation and Privilege: College Choice and Social Reproduction
… who are academically qualified to succeed at a highly selective college or university, but who come from low income families. Such variations in enrollment at highly selective colleges and universities aligned with family income and not academic merit raise important social justice and …

Empowering Connections: The Role of Significant Individuals and Social Networks on the Persistence and Validation of First-Generation Latinx College Students
<p>While attending a highly selective institution provides for greater support and services, the experiences of Latinx college students within this context have not been fully studied. Only recently has the collegiate success of first-generation Latinx college students become a focal point of …

Analytical Potential Of Polymerized Liposomes Bound To Lanthanide Ions For Qualitative And Quantitative Analysis Of Proteins
… of biological systems is the prevalence of highly selective and often very strong interactions among different cellular components. Such interactions play a variety of organizational, mechanical, and physiological roles at the cellular and organism levels. Antigen-antibody complexes are …

Analysis of and process development for high-frequency indium gallium phosphide/gallium arsenide heterojunction bipolar transistors
… These properties include the availability of highly selective etches, an energy band alignment favorable for high injection efficiency devices, and the absence of DX centers.

Reactive ion etching of indium phosphide-based heterostructures and field-effect transistors using hydrogen bromide plasma
A new highly selective reactive ion etching process based on HBr plasma for the removal of InGaAs over InAlAs has been developed and the results are presented. The etch selectivity at a self-bias voltage of $-$100 V is over 160, which is the highest that has been reported for this material system …

The deconstruction of ambition: Campus climate, stereotype threat, and the motivational goals of African American students at a selective small liberal arts college
… students face many challenges when they attend highly selective, predominantly White institutions. Lack of support for or belief in their academic success on the part of White faculty and peers may contribute to a climate in which it becomes increasingly difficult for African American students …

Asymmetric Lithiation-Substitution Sequences of Functionalized Allylic and Benzylic Amines Mediated by (-)-Sparteine
… products were obtained which participated in highly selective Diels-Alder cyclizations. Methyl substitution at the beta-position gave a substrate suitable for mechanistic studies. The addition of a heteroaromatic ring on the allyl backbone provided a substrate that behaved very similarly to …
