A new type of lanthanum‐based high entropy perovskite oxide (HEPO) electrocatalyst for the oxygen evolution reaction is reported. The B‐site lattices in the HEPO consist of five consecutive first‐row transition metals, including Cr, Mn, Fe, Co, and Ni. Equimolar and five non‐equimolar HEPO electrocatalysts are studied for their OER electrocatalytic performance. In the five non‐equimolar HEPOs, the concentration of one of the five transition metals is doubled in individual samples. The performances of all the HEPOs outperform the single perovskite oxides. The optimized La(CrMnFeCo2Ni)O3 HEPO exhibits an outstanding OER overpotential of 325 mV at a current density of 10 mA cm−2 and excellent electrochemical stability after 50 h of testing.
A 1-day, small group discussion education program can effectively improve nurses' knowledge and confidence in critical appraisal. Educators and administrators may replicate this education program to improve the quality of nursing care
In this paper numerous alternative treatments in addition to pharmacological therapy are proposed for their use in epileptic patients. Epileptic animal models can play a crucial role in the performance evaluation of new therapeutic techniques. The objective of this research is to first develop various epileptic rat models; second, develop a portable wireless closed-loop seizure controller including on-line seizure detection and real-time electrical stimulation for seizure elimination; and third, apply the developed seizure controller to the animal models to perform on-line seizure elimination. The closed-loop seizure controller was applied to three Long-Evans rats with spontaneous spike-wave discharges (non-convulsive) and three Long-Evans rats with epileptiform activities induced by pentylenetetrazol (PTZ) injection (convulsive) for evaluation. The seizure detection accuracy is greater than 92% (up to 99%), and averaged seizure detection latency is less than 0.6 s for both spontaneous non-convulsive and PTZ-induced convulsive seizures. The average false stimulation rate is 3.1%. Near 30% of PTZ-induced convulsive seizures need more than two times of 0.5 s electrical stimulation for suppression and 90% of the non-convulsive seizures can be suppressed by only one 0.5 s electrical stimulation.
The purpose of this study attempted to understand the psychological well-being of caregivers of individuals with schizophrenia and factors affecting the caregivers' psychological well-being. More specifically, quality of life and psychiatric morbidity were used to represent the psychological wellbeing. Personal interviews using questionnaires were administrated to 57 caregivers. Data regarding knowledge of schizophrenia, perceived causes of schizophrenia, quality of life and psychiatric morbidity was collected. Psychiatrists assessed the symptoms severity of the schizophrenic patients. Compared with the controls, the psychological well-being of caregivers of patients with schizophrenia was poorer. There was a significant association between the positive symptoms score and the psychological well-being of caregivers. Life quality and psychiatric morbidity were affected by caregivers' knowledge of schizophrenia and beliefs about the cause of schizophrenia. Health care providers should consider the patients and their caregivers as a whole and provide psychoeducaiton to reduce the negative psychological impact of caregivers.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
