“…The high strain energy caused by plastic deformation and nanocrystalline boundary energy provided the driving force of the transformation 16. In particular, it should be noted that there still existed residual Al 2 Cu crystalline peaks, and it was generated by the reaction of Cu 9 Al 4 and Al (Cu 9 Al 4 +Al→Al 2 Cu) 17. The temperature rise caused by grain breakage and deformation made the thermal motion of atoms increase, while the system tended to keep stability through reducing the internal energy.…”

Mechanical alloying of Al 65 Cu 20 Ti 15 powder blend has been carried out by high energy vibrating ball mill. The process of amorphisation in the mechanically alloyed Al 65 Cu 20 Ti 15 powder and the stability of the amorphous phase during ball milling were investigated. Almost completely amorphous powder was achieved after 25 h ball milling. Examination of the microstructural constituents using X-ray diffraction and transmission electron microscopy shows that the amorphisation process was controlled by the transformation of both Al based solid solution and intermetallic compounds (Al 2 Cu, Cu 9 Al 4 and AlCu 2 Ti). However, that prolonging the ball milling time to 30 h led to the appearance of Cu 9 Al 4 , the Al 65 Cu 20 Ti 15 composite comprising nanocrystalline and amorphous phases could be stable after 50 h ball milling.

In the present work, the taxonomic relationship between Streptomyces griseomycini and Streptomyces griseostramineus was reevaluated by a comprehensive comparison of phenotypic, chemotaxonomic and genomic characteristics, as well as phylogeny. Phylogenetic analysis based on 16S rRNA gene sequences and whole-genome sequences indicated that Streptomyces griseostramineus JCM 4385T was clustered together with Streptomyces griseomycini JCM 4382T, suggesting they were closely related to each other. However, the average nucleotide identity (ANI) and digital DNA–DNA hybridization (dDDH) values between their genomes were 99.7 and 97.5 %, respectively, much larger than the recommended threshold values of 96.7 % ANI and 70 % dDDH for Streptomyces species delineation. In addition, the morphological, cultural, physio-biochemical and chemotaxonomic features of these two species further demonstrated that they belonged to the same genome species. Based on the above data and the principle of priority in nomenclature, it is proposed that S. griseostramineus (Preobrazhenskaya et al. 1957) Pridham et al. 1958 (Approved Lists 1980) is a later heterotypic synonym of S. griseomycini (Preobrazhenskaya et al. 1957) Pridham et al. 1958 (Approved Lists 1980).

“…to determine if a fire has occurred. Conventional fire detection sensors have long fire response times (>100 s) and do not provide the best response time for timely fire extinguishing and evacuation 1–6 . And conventional fire detection sensors usually have only a single fire response mode, which often leads to false fire alarms.…”

“…In recent years, nanoparticle temperature sensors with a thermally induced response, represented by graphene oxide (GO), have provided the possibility of shorting fire response time 1,2,11–20 . Its fire warning mechanism is based on the significant decrease in resistance due to the thermal reduction of GO to sense the change in temperature at the fire site.…”

Expandable graphite embedded in flexible polymer surfaces for fire detection in multiple modes

Fire detection sensors are a necessary facility to ensure fire safety. The long fire response time and the false fire alarms caused by a single fire response mode are urgent problems for fire detection sensors. Here, a strategy of embedding expandable graphite (EG) in the sample surface of a styrene‐butadiene‐styrene block copolymer/intumescent flame retardant is used to endow the sample with fire detection in multiple modes and early warning functions, thus shortening the fire warning time and preventing the false fire alarms. The EG improved the flame retardancy of the samples from failing to V‐0 in the vertical burning rating test. The EG also gave the samples the ability to sense tensile and bending deformation. The negative temperature effect of the EG resistance gave the sample an early warning capability for fires with warning temperatures as low as 200°C. The rapid expansion of EG exposed to flame into graphite worms was used for the rapid response of the sample to fire (response time < 1 s). The Seebeck effect with response voltage of up to 0.3 V was used for fire detection of samples based on the temperature difference of EG on the sample surface caused by the flame. This study has potential application prospects for rapid fire warning in buildings.
