AI Article Synopsis
- The study presents the creation and testing of cantilevered glass probe arrays, featuring probes with tapered shafts that measure 175 micrometers square at the base and 200 nanometers square at the tip.
- Each array can include up to eight probes that are 10-20 mm long, spaced 450 micrometers apart, and are made from one glass wafer using dicing and chemical etching techniques.
- The optical signal loss for these probes is approximately 1 dB/cm, indicating their potential use in high-density data storage and efficient page-oriented information retrieval.
Article Abstract
We describe the fabrication and characterization of cantilevered glass probe arrays. Individual probes have tapered shafts that are 175 microm square at the base and 200 nm square at the pyramidal tip. Each array contains as many as eight probes 10-20 mm long at 450-microm center-to-center spacing, fabricated from a single glass wafer by a combination of dicing and chemical etching. Optical signal losses of individual probes were measured to be of the order of 1 dB/cm. High-density data storage and page-oriented retrieval are the potential applications of the arrays.

Polyimides (PIs) have been extensively used in thin film and micro-electromechanical system (MEMS) processes based on their excellent thermal and mechanical stability and high glass transition temperature. This research explores the development of a novel multilayer and multifunctional polymer composite electro-piezomagnetic device that can function as an energy harvester or sensor for current-carrying wires or magnetic field sensing. The devices consist of four layers of composite materials with a polyimide matrix.

We present a low-temperature magnetic force microscope (MFM) incorporating a piezoresistive cantilever and a dual-range scanner for experiments across a wide temperature range from cryogenic levels to room temperature. The piezoresistor-based MFM eliminates the need for optical readjustment, typically required due to thermal expansion at varying temperatures, thereby providing a more stable and precise measurement environment. The integration of a dual scanner system expands the versatility of scanning operations, enabling accurate sample positioning for detailed exploration of magnetic and superconducting properties under diverse thermal conditions.

Unicellular organisms such as yeast can survive in very different environments, thanks to a polysaccharide wall that reinforces their extracellular membrane. This wall is not a static structure, as it is expected to be dynamically remodeled according to growth stage, division cycle, environmental osmotic pressure and ageing. It is therefore of great interest to study the mechanics of these organisms, but they are more difficult to study than other mammalian cells, in particular because of their small size (radius of a few microns) and their lack of an adhesion machinery.

Objectives: The objective of this review was to assess clinical trials that have examined the materials, design, and bonding of ceramic cantilevered resin-bonded fixed dental prostheses (RBFDPs) as a potential option for replacing missing anterior teeth. The evaluation primarily focuses on the rate of restoration failure and clinical complications.
Materials And Methods: A thorough search of databases including PubMed/MEDLINE, Scopus, and the Cochrane Library, was conducted.
