Sarfus is a digital platform that connects vehicle owners with available parking spaces. It helps users find parking spots, often in real-time, and can facilitate the booking and payment processes. The platform aims to alleviate parking challenges in urban areas by optimizing the use of available spaces, reducing congestion, and providing convenience to drivers.
Scanning helium microscopy (SHeM) is a form of microscopy that employs a beam of helium atoms to image surfaces at the nanoscale. This technique is noted for its unique ability to achieve high-resolution images with minimal sample damage, making it particularly advantageous for delicate materials and biological specimens. In SHeM, a fine beam of low-energy helium atoms is scanned across the sample surface.
Scanning probe lithography (SPL) is a set of techniques used to create nanostructures on surfaces with high precision and resolution. It employs a scanning probe, which is a sharp tip or a small device that can manipulate materials at the nanometer scale. The key principle involves scanning a probe over a substrate to induce changes in materials, allowing for the fabrication of nanoscale patterns or structures.
Selective leaching is a process commonly used in metallurgy and mineral processing to extract specific metals or minerals from ores or concentrates. In this technique, certain components of a solid material are dissolved and removed while leaving others relatively intact. This selective dissolution is achieved by using suitable solvents or chemical agents that preferentially interact with the target material. The main features of selective leaching include: 1. **Targeted Dissolution**: The process aims to extract a specific metal (e.g.
Selective organ targeting (SOT) is a strategy used in drug delivery systems, particularly in the field of nanomedicine, to enhance the therapeutic efficacy of drugs while minimizing side effects. The main goal of SOT is to direct therapeutic agents—such as nanoparticles, biologics, or small-molecule drugs—to specific organs, tissues, or cells within the body.
Silanization is a chemical process involving the modification of surfaces, such as silicon and mica, using silane compounds. This process is particularly useful for enhancing surface properties, improving adhesion, and creating hydrophobic (water-repellent) surfaces. Here's an overview of the silanization processes for silicon and mica: ### Silanization of Silicon 1.
Silicon nanowires are nanoscale structures made of silicon that have diameters typically ranging from a few nanometers to several hundred nanometers and lengths that can be several micrometers or longer. These one-dimensional structures exhibit unique electrical, optical, and mechanical properties that differ significantly from bulk silicon due to their reduced dimensionality and increased surface-to-volume ratio.
A single-molecule electric motor is a nanoscale device that mimics the function of a macroscopic motor but operates at the level of individual molecules. These motors utilize electric energy to induce motion within a single molecule, often allowing it to perform mechanical work or exert force at the nanometer scale.
Nanotechnology refers to the manipulation of matter on an atomic and molecular scale, typically at dimensions of 1 to 100 nanometers. Its societal impact is significant and multifaceted, encompassing a range of sectors including healthcare, environmental sustainability, energy, electronics, and consumer products. Below are some key aspects of the societal impact of nanotechnology: ### 1.
Structural coloration is a phenomenon whereby colors are produced not by pigments, but rather by microstructure that interacts with light. This occurs when the physical structure of a material reflects and refracts light in specific ways, resulting in vivid colors that can change based on the angle of observation, the angle of light, and other environmental factors.
Synthetic setae refer to artificial structures designed to mimic the hair-like projections found on various organisms, particularly insects. These projections, or setae, often serve various functions such as sensing environmental stimuli, aiding in movement, or providing adhesion. In the context of synthetic setae, researchers and engineers create materials or devices that replicate these biological features for use in applications such as robotics, adhesives, and biomimetic design.
TectoRNA is a class of RNA molecules that are engineered to exhibit specific three-dimensional structures, often for various applications in synthetic biology, biochemistry, and nanotechnology. The term "Tecto" suggests a connection to the concept of building or assembling, as these RNA molecules can be designed to form complex, nanostructured shapes or frameworks.
Teeny Ted from Turnip Town is a fictional character from an indie game called "Teeny Ted from Turnip Town." The game is a unique and humorous title developed for the **Nintendo Game Boy**, and it gained some notoriety due to its absurd premise and the way it played with the conventions of video gaming.
Thermal scanning probe lithography (tSPL) is a specialized nanofabrication technique that combines scanning probe microscopy with thermal processes to create nanostructures on a substrate. This technique typically involves a sharp tip, similar to that used in atomic force microscopy (AFM), which is heated to a temperature sufficient to induce changes in the material it contacts, such as polymers or other thermally responsive materials.
Thermochemical nanolithography is a specialized nanofabrication technique used to create nanostructures with high precision. It combines thermal and chemical processes to pattern materials on a nanoscale. ### Key Aspects of Thermochemical Nanolithography: 1. **Temperature Control**: The process typically involves a scanning probe that applies localized heat to a surface. This localized heating can cause specific chemical reactions or changes in the material beneath the probe.
The thermodynamics of nanostructures deals with the principles and behaviors of thermal energy in materials at the nanoscale, typically involving structures that are on the order of 1 to 100 nanometers in size. This field is particularly important because materials at the nanoscale can exhibit unique physical and chemical properties that differ significantly from their bulk counterparts due to high surface area-to-volume ratios, quantum effects, and increased significance of surface energy.
Tissue nanotransfection is a novel biomedical technique that allows for the delivery of genetic material, such as DNA, RNA, or proteins, into specific cells within tissues using nanoscale technology. This method is particularly notable for its potential applications in regenerative medicine and gene therapy. The process typically involves the use of a small device or nanoparticle that can perforate the cell membrane to facilitate the entry of genetic material into the target cells.
Tunable resistive pulse sensing (TRPS) is an advanced analytical technique used to characterize nanoscale and microscale particles, such as biological cells, viruses, and synthetic nanoparticles. It is primarily employed in fields like biophysics, diagnostics, and material science. The core principle of TRPS involves monitoring changes in ionic current as particles pass through a nanopore or a microchannel.
Utility fog is a theoretical concept coined by researcher J. Storrs Hall in the early 1990s. It refers to a swarm of tiny autonomous robots, often imagined as nanobots or microscopic machines, that can work together to create a dynamic, shape-shifting mass of matter. This "fog" could be utilized for various purposes, such as altering its shape and texture to create objects, providing environmental control, or enabling new forms of interaction between humans and machines.
