An AIE-based fluorescent probe was developed for monitoring food spoilage<italic>via</italic>its response toward hydrogen sulfide.

α-ZrP was combined with polyphosphazene and formed a core–shell structure, which has significant synergistic flame retardant performance in polypropylene.

Molybdenum disulfide (MoS 2 ) with two‐dimensional (2D) lamellar structure was functionalized melamine‐cyanuric acid (MCA) hybrids via a facile way. A core‐shell composite particle (MoMA) obtained. Acting as one kind of synergistic flame retardant, it mixed traditional intumescent retardant (IFR) to prepare the poly(lactic acid) composites by melt blending. UL‐94 V‐0 rating and LOI value 29.8% for PLA were achieved while total amount retardants 12 wt%, optimal weight ratio IFR MoMA 3:1. The...

The working environment of agricultural knives is bad, which makes the wear out easily. A resistant layer AlCoCrFeNi high entropy alloy (HEA) reinforced by tungsten carbide (WC) was prepared laser cladding on one side cutting edge a 65 Mn silage knife. Both effects WC addition microstructure and mechanical properties (WC)x (x = 0, 0.1, 0.2 0.3 in mass percentage) alloys were investigated. All experimental displayed crystalline structure simple body centered cubic (BCC). hardness increases...

Viscosity is an important quality parameter for fluid drinks, which can serve as indicator the extent of food spoilage, since viscosity drinks varies during spoilage process. In this study, a near-infrared fluorophore based on tetranitrile-anthracene (TPAEQ) was designed determination via aggregation-induced emission (AIE). With increased viscosity, TPAEQ showed enhanced at around 759 nm with large Stokes shift 195 in water. The probe successfully used to monitor changes process drinks....

Heat shock response (HSR) is a ubiquitous cellular mechanism that copes with variety of stresses. This mediated by family transcriptional activators, heat factors (HSFs), which are under tight regulation. HSF binding protein 1 (HSBP1) negative regulator HSR and reported to bind specifically the active trimeric form HSF1, thus inhibiting its activity. HSBP1 contains heptad-repeats in primary sequence was believed stay trimer solution. We report crystal structure trimerization domain M30I/L55P...

Al1.8CrCuFeNi2 high-entropy alloy coatings with different TiC contents were prepared using laser cladding. The effect of on the microstructure, hardness and wear resistance was investigated. It found that phase structure coating 10 wt.% a single BCC no other precipitated phase. When 20 added, content increased to 30 wt.%, more TiC-reinforcing formed. With increase in content, enhanced loss clearly decreased, which closely related change structure. addition alloys plays role fine-grain...

Viscosity is one of the most important physical parameters in a liquid, noninvasive, and effective viscosity inspection method toward liquid safety that needs to be developed urgently. In this study, two kinds novel molecular sensors, namely, DPBID DPTMID, were strategically constructed by triphenylamine indanedione derivates; rotatable conjugate structure was utilized as recognition site fluorescence quencher. This couple sensors synthesized one-step facile manner. DPTMID displayed longer...

ABSTRACT A new kind of flame retardant (ZS) with layered α‐zirconium phosphate disks (α‐ZrP) as the core and inorganic (gel‐silica, GS) to shield solid acid sites on surface α‐ZrP shell, was synthesized via a facile method. The incorporation effects ZS silicone resin thermal properties retardance PC composites were investigated. presence could improve stability matrix. With addition contents increased 3 wt %, limiting oxygen index (LOI) composite 32.3% vertical burning (UL‐94) test reached...

Liquid safety is considered a serious public health problem; convenient and effective viscosity determination method has been regarded as one of the powerful means to detect liquid safety. Herein, kind triphenylamine-modified cinnamaldehyde-based fluorescent sensor (3-(4'-(diphenylamino)-[1,1'-biphenyl]-4-yl)acrylaldehyde (DPABA)) developed for sensing fluctuations in system, where cinnamaldehyde derivative was extracted from natural plant cinnamon acted an acceptor, which combined with...

As the main substate participating during liquid metamorphism processes, abnormal micro-environmental viscosity is closely associated with occurrence and development of objective circumstance degradation. Thus, it great importance to establish convenient detection method toward monitoring. This work focused on extracting one kind erucic acid-based molecular probe (EAd) for sensing fluctuations in liquids. The electron donor phenolic hydroxyl group acceptor carboxyl have established this...

Naphthalene anhydride triphenylamine as a viscosity-sensitive rotor was designed for carrying out fluorescence investigations on beverage deterioration.

In this paper, the effects of different melt spinning speeds on mechanical properties (TiZr)0.5(Ni0.6Cr0.1V0.1)2.1 amorphous ribbons were studied. Tensile tests specimens used to investigate behavior and ribbons. The cooling rate glass transition temperature was discussed. correlation between microstructure serrated flow in stress-strain curves also evaluated. addition, when speed 45 m/s, a large number dense uniform dimples appeared fractured surface specimens. Furthermore, characteristics...
