CTE of CNT Epoxy Composite
The document discusses a novel process for creating aligned carbon nanotube-polymer composites with extremely low coefficients of thermal expansion. It involves two key steps: 1) in situ functionalization of the carbon nanotubes to enhance bonding with the polymer matrix, and 2) microwave curing of the composite to selectively heat the interface and further strengthen bonding. Composites created with this combined process showed a 90% reduction in through-thickness thermal expansion above the glass transition temperature compared to the polymer alone. This represents an important advance toward using such composites as thermal interface materials.
PASS-CATCH Presentation
Physical activity improves elementary school students' achievement test scores. A study found that students who received 60 minutes per day of physical activity through enhanced PE, classroom activities, and recess saw significantly greater gains in math scores over time compared to students in non-active classrooms. These effects were particularly pronounced for students identified as having difficulties adapting to school. The active students also showed significantly higher reading scores compared to their less-active peers. The study demonstrates that physical activity can improve academic performance, especially for students struggling in school.

EPD Resin Clay Composite
This document discusses the preparation of acrylic anodic electrophoretic resin (AAER)/clay nanocomposite films through an aqueous electrodeposition process. Key findings include:
1) Polymer/clay nanocomposite films with well-dispersed montmorillonite platelets were prepared using an aqueous suspension of AAER and sodium montmorillonite.
2) Characterization methods like XRD, SEM, and TEM indicated an intercalated or exfoliated morphology with mono-disperse hexagonal clay platelets at low clay loadings.
3) The aqueous compatibility between AAER and clay, along with the water-based electrodeposition process, contributed to the ideal clay dispersity
Worldcup2010 gs report
1) The World Cup provides an opportunity to raise awareness and funds for the 1GOAL campaign to ensure 72 million children in Africa receive a primary school education. Education has significant social and economic benefits by reducing poverty, disease, and increasing long-term economic growth.
2) Studies show that every extra year of quality schooling increases a country's annual GDP growth by 1% on average. Education also boosts individual earning potential and national innovation.
3) Investing in primary education, especially for the poorest countries, has one of the highest rates of return. Ensuring all children can attend primary school would require an additional $12 billion annually from governments worldwide.
E Mails And Twitter By Tat[1]
E-mails and Twitter discusses the advantages and disadvantages of using electronic communication tools like email and Twitter in education. Some advantages of email include communicating with students and teachers, posting questions online, and collaborating on projects with other classrooms. Twitter allows students to follow people in careers they admire and improve their writing. However, overreliance on computers can make children lazy and less imaginative as they don't have to work as hard to find information. Computers also provide a cold way of teaching compared to live instruction.

The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive function. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms for those who already suffer from conditions like anxiety and depression.
nanographite Composites
This document summarizes a study that models the thermal conductivity of graphite nanosheet (GNS)/epoxy composites. An effective medium model is used to analyze how the thermal conductivity of these composites is affected by the aspect ratio and orientation of the GNS, as well as the interfacial thermal resistance between the GNS and polymer matrix. The model predicts that the interfacial thermal resistance between GNS and polymers is about one order of magnitude lower than between carbon nanotubes and polymers, potentially explaining the high thermal conductivity observed experimentally for GNS/epoxy composites.
CNT-polymer interface
This document summarizes and critiques a recent study on stress transfer within double-walled carbon nanotubes (DWNTs). The study found that only the outer wall of DWNTs shifted under strain, indicating poor stress transfer between walls. However, this document argues that:
1) The assumption that Raman shift rate correlates with modulus does not necessarily hold for CNTs due to differences in microstructure compared to carbon fibers.
2) Interface effects are more important for CNT/polymer composites and could explain Raman response differences instead of intrinsic modulus differences.
3) The concept of "effective modulus" was used confusingly in the original study. The document argues there is no evidence DWNTs have

Teori teori organisasi & komunikasi organisasi
Komunikasi merupakan proses penting dalam organisasi. Terdapat dua jenis komunikasi utama yaitu komunikasi formal yang berkaitan dengan tugas dan kepentingan organisasi, serta komunikasi informal yang lebih bersifat sosial antar anggota. Komunikasi efektif memerlukan pengertian mengenai arah, jaringan, dan hambatan komunikasi dalam organisasi.
