A small number of previous studies focused on cooktop fire sources and considered multi-detector sensing of pre-ignition signatures in a kitchen environment. Johnsson conducted a series of experiments investigating the feasibility of distinguishing between
This paper provides a report of the discussions held at the first workshop on Measurement and Computation of Fire Phenomena (MaCFP) on June 10-11 2017. The first MaCFP workshop was both a technical meeting for the gas phase subgroup and a planning meeting

Steel buildings subjected to structurally significant fires experience thermal assault comprising elevated temperatures and non-uniform thermal gradients, which may induce both temperature-dependent degradation and large unanticipated loads in the steel
The structural performance of a set of ASCE 7 code-compliant archetypical reinforced concrete moment frame buildings is assessed using Tier 3 analysis procedure in ASCE 41.In recent years, practicing engineers increasingly use ASCE 41 as an standard to
The anticipated performance of 4- and 8-story reinforced concrete (RC) buildings designed in accordance with ASCE/SEI 7-10, is assessed using ASCE/SEI 41. Engineering practitioners are increasingly using ASCE/SEI 41, as the guideline to implement the
A kinetic model for 2,3,3,3-tetrafluoropropene (HFO-1234yf) high temperature oxidation and combustion is proposed. It is combined with the GRI-Mech-3.0 model, with the previously developed model for 2-bromo-3,3,3-trifluoropropene (2-BTP), and with the NIST
Screening methods for refrigerant blend flammability from metrics that can be easily calculated are of great interest to the refrigerant industry. Existing flammability metrics such as heat of combustion are not adequate for hydrofluorocarbon blends
Due to their high global warming potentials, many existing working fluids for heating, cooling and refrigeration equipment are being phased out. Their replacements will often be flammable or slightly flammable, and the burning velocity of refrigerant-air

As the structural engineering industry transitions towards performance based design methods, a better understanding of the performance of structures as full systems, especially under extreme loading conditions like fire, becomes a must. Full scale testing

The Net Zero Energy Residential Test Facility (NZERTF) was constructed at the National Institute of Standards and Technology (NIST) to support the development and adoption of cost-effective net zero energy designs and technologies. The 250 m2 two-story
The engineering design practice may include fire protection design of steel structures in large volumes. Prescriptive methods in fire codes are based on the concept of fire compartmentation and might be inapplicable to large volumes. As an alternative
The response of structural systems to fire loads is typically assessed through performing standard tests under constant mechanical boundary conditions. Such tests are usually performed on the individual elements. Full scale tests showed differences in

We report a family of flame-retardant electrolytes for lithium batteries based on ionic nanocomposites. The nanocomposites are synthesized in one pot by dispersing SiO2 nanoparticles charge-balanced by both Li ions and mono-amino-terminated polyether (PEO

A series of cooking fire experiments were conducted by the National Institute of Standards and Technology (NIST) to examine the hazard associated with cooking oil fires. First, a series of experiments were conducted on a free-standing stove situated in the
NIST hosted workshop, Future Needs for Reducing the Fire Hazard of Materials, provided an opportunity for worlds experts to come together to discuss the challenges associated with reducing the fire hazards of existing and future products that compose the
Due to their high global warming potentials, many existing working fluids for heating, cooling and refrigeration equipment will be phased out. Their replacements will be flammable or slightly flammable, and the burning velocity of refrigerant-air mixtures
The general purpose of underground gas storage (UGS) is to meet varying demand for natural gas (methane, CH4) over daily to seasonal time scales in the face of constant rate gas production and limited pipeline transport capacity. In California, UGS is used
