Top Research Papers on Nanotechnology

The present review provides an overview of the recent advances of nanotechnology in the aspects of imaging and drug delivery.

Even if nanotechnology is no more than a small mutation in the industrial ecosystem, it is recognized that production of “nanostuff” itself requires energy and possibly toxic chemicals. . . . [And] if there are concerns over the impacts of nanomaterials in the environment, then this provides an incentive for one of the main goals of industrial ecology: “closed loop” use of materials. human production– consumption systems with natural systems. It supports the design and governance of these systems to form an integrated industrial ecosystem that has “ecological integrity and provides humans with...

A multidisciplinary field that strives to comprehend the interactions of cellular components, molecular components and engineered materials at the nanoscale, wherein unique phenomena enable novel applications.

This paper outlines cement and concrete properties that challenge engineers and discusses the benefits that could be derived from changes in the smallest structure of cementitious and other concrete materials. Concrete is the most widely used building material in the world. Roman concrete structures still exist today. Even with concrete's versatility and durability, certain properties continue to pose challenges. The ability to modify essential molecular building blocks provides the potential to make great strides in reducing or eliminating numerous mechanisms that can compromise the life of c...

Nanomaterials have been the object of numerous public and private initiatives aiming to manage their risks and maximise their benefits. Proponents of nanotechnology programmes argue that their potential negative impacts need to be dealt with appropriately, and wish to integrate these concerns early in the industrial development of these substances. Science policy programmes do not provide a clear definition of the term “nanomaterials”. Defining nanomaterials, however, has become a central concern. It is called for by manufacturers who wish to sell the “nano” quality of their products as well a...

With the advances in the field of nanotechnology, manufacture of nanorobot is expected to be created in the next 10 years and this automatic molecular machine can swim in human blood, can view full cellular details, can monitor levels of different compounds, and can store that information.

Nanotechnology is a hot topic in most science and technology libraries. The literature of nanotechnology is widely scattered across traditional disciplines. This paper provides an introduction for the non-expert to key terminology, reference works and indexes to the literature of nanotechnology. [ABSTRACT FROM AUTHOR]

This article attempts to address some of misconceptions about nanotechnology, and explain why scientists, businesses and governments are spending large amounts of time and money on nanoscale research and development.

Nanotechnology-assisted drugs can penetrate the blood-brain barrier and reach the target tissue, however, further research is required in this field, to ensure the safety and efficacy of drug-loaded nanoparticles.

A recently derived framework for definitions of these terms is discussed and it is suggested that nanotechnology-related terms such as “nanofiltration” and “silicon-spotting” should be considered as separate categories.

Challenges for translation of these advanced nano-based techniques for clinical applications and their green synthesis are highlighted.

Food packaging is a critical technology addressing the ever-increasing demands for convenience, freshness, ease, shelflife, safety and security of food products. The main purpose of food packaging is to protect the food from microbial and chemical contamination, oxygen, water vapour and light. The type of packaging used therefore has an important role in determining the shelf-life of the food. Nanotechnology can be intervened to achieve the purpose of food packaging and it will become one of the most powerful forces for innovation in the food packaging industry. Nanoscience and nanotechnology ...

In this study, flower-like In2S3 hierarchical nanostructures were successfully prepared via a facile solution-phase route, using thioacetamide as both sulfur source and capping agent and photocatalytic activity studies revealed that the prepared indium(III) sulfide(In2S 3) nanoflowers exhibit an excellent photocatalyst performance, degrading rapidly the aqueous pharmaceutical solution of Lisinopril under visible light irradiation.

This review focuses on the use of NMs in disease management through three different mechanisms: 1. as antimicrobial agents, 2. as biostimulants that induce plant innate immunity, and 3. as carriers for active ingredients such as pesticides, micronutrients, and elicitors.

This review delves into the application of nanotechnology in diagnosing and treating ASD and shedding light on the promising role of nanoparticles, allowing for the more targeted and efficient administration of medications.

The purpose of this review is to investigate different nanoparticles for the detection and effects of antibacterial, anti‐biofilm, and anti‐infestation assays against the human pathogen S. agalactiae.

This article provides an overview of nano-electromechanical (NEMS) and micro-electromechanical (MEMS) systems and discusses ongoing research activities exploring potential applications for these systems. Advances in nano- and microtechnology have made it possible to manufacture small, intelligent, low-cost wireless devices that can be placed in concrete during mixing to provide real-time monitoring of workability and early-age properties. These devices also have potential application in detecting environmental and structural damage. A pilot study was conducted to investigate the feasibility of...

This paper is intended to provide a history of web exceptionalism from 1989 to 2009, a period chosen in order to explore its roots as well as specific cases up to and including the year in which descriptions of “Web 2.0” began to circulate.

The article proposes to orient and expand legal doctrinal studies of law–making and law enforcement operations — the “atoms” of legal activity and the creation of structures from them, from which the social and legal-technical adequacy of normative legal acts, legal certainty, uniform law enforcement, and the ordering of public relations should arise. Natural sciences penetrate into smaller and smaller particles of nature — up to billionths of objects (nano). From small sizes, due to changes in the structure of materials, new properties arise — the results of technological progress. Nizhny Nov...

Nanotechnology is an Interdisciplinary and integrates the science and technology. This technology is the materials at nanodimension. The approach at nanodimension towards manufacturing and fabrication will responds to the challenge for future competitiveness of much of the economy. Preparation of materials at nanodimension supports the growth of nanotechnology and which routes the nanotechnological applications. The emerging research materials are in the research stage and would be used in nanometer scale devices. Development of characterization technology is needed to understand the compositi...
