Microbial fuel cells (MFCs) are a promising technology for obtaining energy in wastewater. Effective extracellular electron transfer is one of the key factors for its practical application. In this work, carbon dots (CDs) enriched with oxygen-containing groups on the surface were synthesized as an efficient anode modifier using a simple hydrothermal method and common reactants.

Although transition metal-nitrogen-codoped carbon materials are an important class of ORR catalysts, copper-nitrogen-codoped carbon is not considered a suitable MFC cathode catalyst due to the insufficient performance and especially instability. Herein, we report a three-dimensional (3D) hierarchical porous copper, nitrogen, and boron codoped carbon (3DHP Cu-N/B-C) catalyst synthesized by the dual template method.

Objective: To understand the characteristics of patients with mimicking specificity autoantibodies through the analysis of the causes of autoantibodies, specificity of antibodies, strategy of blood transfusion, effect of transfusion and distribution of antibodies in China and abroad.
Methods: A total of 23 patients who applied for blood in our hospital from January 2017 to June 2019 were identified as mimicking specificity autoantibodies by antibody identification or absorption-elution test. The causes of mimicking specificity autoantibodies, antibody specificity, blood transfusion strategy and blood transfusion effect were analyzed.
Background: The vital signs of trauma patients are complex and changeable, and the prediction of blood transfusion demand mainly depends on doctors' experience and trauma scoring system; therefore, it cannot be accurately predicted. In this study, a machine learning decision tree algorithm [classification and regression tree (CRT) and eXtreme gradient boosting (XGBoost)] was proposed for the demand prediction of traumatic blood transfusion to provide technical support for doctors.
Methods: A total of 1371 trauma patients who were diverted to the Emergency Department of the First Medical Center of Chinese PLA General Hospital from January 2014 to January 2018 were collected from an emergency trauma database.

Fruit and vegetable waste (FVW) is become a serious problem in developing countries. Enzymolysis is a potentially useful method for the treatment of FVW. In the present study, novel recycled magnetic molecular imprinting immobilised cellulases were prepared based on magnetic modified chitosan (MCTS) and FeO.

Objective: To evaluate the effects of the 25 Gy ⁶⁰Co irradiation on the physiological and biochemical properties and the functions of the platelets during storage.
Methods: A total of 15 bags of platelets were apheresis-collected from 15 healthy donors, and each bag of platelets were divided into 2 parts, then the platelets were divided into the control group (without 25 Gy ⁶⁰Co irradiation) and the irradiated group (with 25 Gy ⁶⁰Co irradiation) groups. The two groups of platelets were kept under the condition of (22 ± 2) °C and shaken.

This study was aimed to analyze the serological characteristics, efficacy and safety of incompatible RBC transfusion in patients with autoimmune hemolytic anemia (AIHA). The patients with idiopathic or secondary AIHA were analyzed retrospectively, then the serological characteristics and the incidence of adverse transfusion reactions were investigated, and the efficacy and safety of incompatible RBC transfusion were evaluated according to the different autoantibody type and infused different RBC components. The results showed that out of 61 cases of AIHA, 21 cases were idiopathic, and 40 cases were secondary.
