“…Wang et al characterized, by using electrochemical impedance spectroscopy (EIS) and CV, an LNT (LaNi 0.5 Ti 0.5 O 3 ) -modified carbon electrode (MCE), which represented the starting point in the construction of an electrochemical sensor used for detecting 4 amino acids: L-cysteine (L-Cys), L-tryptophan (L-Trp), L-alanine (L-Ala) and L-Phe. The amino acid sensor showed good reproducibility, long-term stability and fast amperometric response [63]. A low LOD and a high sensitivity were obtained as compared to those previously reported in the domain-specific research.…”

Phenylalanine is an amino acid found in breast milk and in many foods, being an essential nutrient. This amino acid is very important for the human body because it is transformed into tyrosine and, subsequently, into catecholamine neurotransmitters. However, there are individuals who were born with a genetic disorder called phenylketonuria. The accumulation of phenylalanine and of some metabolites in the body is dangerous and may cause convulsions, brain damage and mental retardation. Determining the concentration of phenylalanine in different biologic fluids is very important because it can provide information about the health status of the individuals envisaged. Since such determinations may be made by using electrochemical sensors and biosensors, numerous researchers have developed such sensors for phenylalanine detection and different sensitive materials were used in order to improve the selectivity, sensitivity and detection limit. The present review aims at presenting the design and performance of some electrochemical bio (sensors) traditionally used for phenylalanine detection as reported in a series of relevant scientific papers published in the last decade.

“…For spallation, the early researches were focused on the effect of the microstructure of materials in single‐phase alloys, such as grain, grain boundary, and inclusion . For example, Furnish and Chhabildas discovered that the void nucleation position of the tantalum samples was related to the initial grain size of the samples—the samples with a grain size of 20 μm had a wider void distribution area than the samples with a grain size of 40 μm.…”

“…The results showed that intermetallic particles initiated microstructural damage during shock loading and reduced spall strength. Similarly, Yang et al took high‐purity oxygen‐free copper as the object of study and discussed the effects of grain boundary type, grain orientation, and grain size on the spallation behavior of high‐purity copper. However, the influence of phase interface on the nucleation and evolution of dynamic damage in multiphase alloys is still unclear.…”

The dual‐phase steel sample obtained by step quenching (SQ) of AISI 1020 steel is shock loaded using one‐stage light‐gas gun experiments. The free surface particle velocity is measured by Doppler pin system (DPS) during the loading experiment. The effect of phase interface on spallation damage nucleation and evolution in dual‐phase steel is investigated with optical microscopy (OM), nanoindentation, and electron backscatter diffraction (EBSD) techniques. The evolution mechanism of spallation damage in dual‐phase steel is systematically analyzed. The results show voids nucleated within martensite rather than at the martensite/ferrite interface under dynamic loading. The nucleation of voids in martensite was not random, the martensite block boundaries with a great Taylor Factor (TF) mismatch and a large angle to the impact direction were the preferred nucleation positions of the voids. Voids nucleate, grow and further coalesce into microcracks. Most of the microcracks propagate across the phase interface and the propagation direction hardly deflects. Due to the existence of many martensite blocks with high‐angle grain interface boundaries inside the martensite, the resistance of microcracks propagation in martensite is greater than that in ferrite. Furthermore, the size of microcracks is related to the angle between the direction of martensite blocks and shock direction.

“…Several studies [17] have been devoted to devising an efficient way to improve the electrochemical sensitivity of semiconductor sensor. For example, Wang et al [18,19] built a sensitive electrochemical sensor for amino acids based on perovskite LaNi 0.5 Ti 0.5 O 3 modified carbon paste electrode. The reported sensor was applied to the detection of cysteine, tryptophane, alanine and phenylalanine.…”
