Antimicrobial Activity of Single-Walled Carbon Nanotubes Suspended in Different Surfactants

We investigated the antibacterial activity of single-walled carbon nanotubes (SWCNTs) dispersed in surfactant solutions of sodium cholate, sodium dodecylbenzene sulfonate, and sodium dodecyl sulfate. Among the three surfactants, sodium chol...

Light Absorption and Emission by Defects in Doped Nickel Oxide

Nickel oxide is a versatile p‐type semiconducting oxide with many applications in optoelectronic devices, but high doping concentrations are often required to achieve necessary electrical conductivity. In contrast to many other transparent ...

Synergistic heterojunction effects in Ag3PO4/SnO2 nanocomposites: a photocatalytic study on isoproturon degradation

IntroductionPesticides such as isoproturon are widely employed and represent a considerable environmental concern. The development of sustainable and efficient degrading techniques is crucial. Photocatalytic degradation employing semiconduc...

Hybrid coatings for orthopaedic implants formed by physical vapour deposition and microarc oxidation

This study is focused on the preparation of new hybrid layers intended for surface modification of Ti-6Al-4V alloys for potential orthopaedic and dental applications. Combination of the technology of physical vapour deposition (PVD) and sub...

Comparative Study of Field-Effect Transistors Based on Graphene Oxide and CVD Graphene in Highly Sensitive NT-proBNP Aptasensors

Graphene-based materials are actively being investigated as sensing elements for the detection of different analytes. Both graphene grown by chemical vapor deposition (CVD) and graphene oxide (GO) produced by the modified Hummers’ method ar...

How interdisciplinary is nanotechnology?

Facilitating cross-disciplinary research has attracted much attention in recent years, with special concerns in nanoscience and nanotechnology. Although policy discourse has emphasized that nanotechnology is substantively integrative, some ...

Nanotechnology in Textiles

Increasing customer demand for durable and functional apparel manufactured in a sustainable manner has created an opportunity for nanomaterials to be integrated into textile substrates. Nanomoieties can induce stain repellence, wrinkle-free...

Nanotechnology in Drug Delivery

Nanotechnology and Cancer

The biological picture of cancer is rapidly advancing from models built from phenomenological descriptions to network models derived from systems biology, which can capture the evolving pathophysiology of the disease at the molecular level....

Photography and archaeology

Through photographs we preserve the past, and looking for the past is the very job of the archaeologist. But what are we looking at in an archaeological photograph? Archaeological photography is often largely deserted, to be scanned with a ...

Emotion in Archaeology

Despite the establishment of significant traditions of emotion research in many disciplines, there has been little discussion of the state and potential of the archaeological study of emotion. This paper aims to review archaeological approa...

Symmetrical archaeology

Symmetry is an epistemological and ethical principle developed in the social study of scientific practice. This essay connects a symmetrical archaeology to major trends in the discipline since the 1960s and to key components of archaeologic...

Ethnographic Archaeologies: Reflections on Stakeholders and Archaeological Practices

1 The Ethnographic Turn in Archaeology: Research Positioning and Reflexivity in Ethnographic Archaeologies 2 A Critical Assessment of Ethnography in Archaeology 3 A Dangerously Elusive Method: Disciplines, Histories, and the Limits of Refle...

Calvatone: gli scavi del vicus romano di Bedriacum

Da quasi trent’anni gli scavi dell’Università degli Studi di Milano a Calvatone (CR), diretti dalla prof. Maria Teresa Grassi, stanno riportando alla luce i resti dell’antico vicus romano di Bedriacum, importante centro strategico e commerc...

Analytical Chemistry Methods of Estimating the Original Firing Temperature of Bricks from a 19th Century Convent in the Philippines: Perspective of a Southeast Asian Country | Mga Pamamaraan ng Mapanuring-Kimika sa Pagtantya ng Orihinal na Temperatura ng Pagsunog sa Ladrilyo Mula sa Isang Ika-19 na Siglong Kumbento sa Pilipinas: Pananaw ng Isang Bansa sa Timog-Silangang Asya

Countries in Southeast Asia have a unique and diverse culture due to its varied ethnic groups having different traditions and beliefs. The process of manufacturing building materials such as brick masonry is one aspect where this distinctiv...
