    In this study, we have successfully fabricated Y 1 receptor ligand (NPY)-modified bubbles, and examined their therapeutic efficacies as size-dependent functions with or without NPY targeting. To achieve this, four types of micro-scale bubbles (MBs or MBs-NPY) and nano-scale bubbles (NBs or NBs-NPY) were comprehensively evaluated.

    The ISCC–NBS System of Color Designation is a system for naming colors based on a set of 12 basic color terms and a small set of adjective modifiers. It was first established in the s by a joint effort of the Inter-Society Color Council, made up of delegates from various American trade organizations, and the National Bureau of Standards, a US government agency. Program on Methods of Measurement for Semiconductor Materials, Process Control, and Devices. It summarizes work on a wide variety of measure-ment methods that are being studied at the National Bureau of Standards. Since the Program is a continuing one, the results and conclusions report-ed here are subject to modification and refinement. 1.

    NBS: Materials measurements. By. Abstract. Measurements in an Auger spectrometer of surface impurity concentrations on liquid gallium showed that the principle impurities were oxygen and carbon. The impurities showed a tendency to collect into plates or clumps. In Pb rich Pb-Sn off eutectic alloys, macrosegration caused by solutal convection. NBS is a global leading technology platform that combines the best content and connectivity for anyone involved in the design, supply and construction of the built environment. Thousands of users interact daily with our tools to create specifications, find products and develop their digital models.

NIST's activities are organized into laboratory programs that include nanoscale science and technology, engineering, information technology, neutron research Agency executive: Walter Copan, Under Secretary.

The NBS/NIST Special Publication series, first published as the NBS Miscellaneous Publication series, is comprised of material that, because of its character or size, does not fit into any of the other regular publication series. The Miscellaneous Publications series was published from means it’s official.

This reference material (RM) is intended for normalization of stable hydrogen (δ. H) and carbon (δ. C) measurements of unknown oils and similarly-behaving hydrogen- and carbon-bearing. This RM consists of µL of NBS 22 oil [1] sealed in a silver tube [2].

This RM is issued in quantities of 50 sealed silver tubes per bottle. 1. Introduction. The need for a large-area, low-intensity alpha test source for large face area ion chambers triggered memories: first, site and area measurements with sensitive radiation monitors at the National Institute of Standards and Technology (NIST) and its predecessor agency, the National Bureau of Standards (NBS) had indicated that the general radiation level was higher in an.

matrix material. The measurement geometry is still the same as that shown in Figurebut the absorption by the matrix material is an added factor in the measurement. Exhaustive summaries of the theory of this type of measurement have been published (Refs.

Title: Catalog of NBS standard reference materials Volume of NBS special publication: Author: National Measurement Laboratory (U.S.). Office of Standard Reference Materials. At NBS, our vision is to be the information platform for the construction industry.

Our mission is to use the power of connected data to add value and enable a safe, efficient, high-quality industry. In this article Dr Stephen Hamil, Innovation Director for NBS, takes us through the reasons behind the development our new platform NBS Source.

The book sizes and dimensions listed on this page and throughout most of our site are rounded measurements. These sizes are only guidelines to approximate sizing, and should not be used in order to design an actual book or magazine.

Material synthesis. Bulk NbS 2 (b-NbS 2) powders were synthesized by the conventional solid-state sulfidization reaction. 1 g Nb 2 O 5 and 5 g S raw materials were loaded into two individual boats, and were placed in the middle and upstream of.

The transport measurements on thin-layered 3R-NbS 2 with different thickness show that 3R-NbS 2 with thickness down to 2D limit (3L) is still metal, being consistent with DFT-based calculations. The synthetic methodology developed here can be easily applied to the growth of many other 2D layered metallic systems, and thus offers new fundamental.
