This paper describes a proposal on intelligent wearable sensor suit intended for being used by firemen. The main purpose of the suit is to monitor an internal health state of the fireman who wears the suit as well as parameters of external environment where the fireman is situated. As external parameters, inflammable and toxic gases are mainly considered thus the fireman can avoid danger from b...

We have developed a simple colorimetric sensor array that detects a wide range of volatile analytes and then applied it to the detection of toxic gases. The sensor consists of a disposable array of cross-responsive nanoporous pigments with colours that are changed by diverse chemical interactions with analytes. Although no single chemically responsive pigment is specific for any one analyte, th...

Multidimensional polypyrrole nanotubes (MPPy NTs) were successfully fabricated as chemiresistors on a sacrificial nanofiber template by vapor deposition polymerization (VDP) and used to discriminate volatile organic compounds (VOCs) and toxic gases.

This work reveals that furfural and 2-thenaldehyde can readily react with melamine via "one-step" polycondensation to yield hyper-cross-linked sulfur-, nitrogen- and oxygen-rich microporous polyaminals with promising applications in adsorption of gases and toxic organic vapors.

Introduction Activated carbon has long been used as a gas adsorbent for respirator applications. Untreated activated carbon poorly adsorbs low molecular weight, highly polar gases such as HCN, SO2 and NH3. The addition of impregnants such us metal oxides, metal chlorides and metal carbonates have been known to react with specific challenge gases within the activated carbon pores facilitating th...

Occupational neurotoxic diseases have become increasingly common in Taiwan due to industrialization. Over the past 40 years, Taiwan has transformed from an agricultural society to an industrial society. The most common neurotoxic diseases also changed from organophosphate poisoning to heavy metal intoxication, and then to organic solvent and semiconductor agent poisoning. The nervous system is ...

A fire experiment conducted in a British 1950s-style house is described. Measurements of temperature, smoke, CO, CO2 , and O2 were taken in the Lounge, stairwell, and front and back bedrooms. The front bedroom door was wedged open, while the door to the back bedroom was wedged closed. Contrary to expectations and despite the relatively small fire load, analysis and hazard calculations show perm...
