The four biological enzymes encompassing alkaline phosphatase (ALP), aminopeptidase N (APN), γ-glutamyl transferase (GGT), and Cathepsin B (CTB), play a pivotal role in a myriad of physiological and pathological processes. Hence, the detection of the five indexes could own an important value in the diagnosis of clinical diseases even the subsequent treatments, which is restricted by a traditional method

Metal organic frameworks (MOFs) are very exciting porous materials owing to their unique properties such as high surface areas, high pore volume, tunable functionalities and great thermal stabilities. The properties of MOFs can be diversely constructed by precise control of synthesis conditions. Amongst the thousands of MOFs that have been discovered to date, Fe-MOFs make up a percentage of these MOFs

In this study, the individual corrosion results of the dissimilar metals revealed that at the onset of exposure to simulated deep-sea environment of 5000 m sea depth, the corrosion potential of 304 SS (-148 mV vs Ag/AgCl) was more positive than that of TC4 (-191 mV vs Ag/AgCl). However, with the progress in exposure time beyond 37.3 ks, the corrosion potential of TC4 became more positive than that

Lithium-containing magnesium alloys are promising materials for high-demanding industrial applications. In the present contribution, three different AZ31 magnesium alloys AZ31-xLi (x = 4, 8, and 12 wt.%) were cast and their corrosion processes were examined in 0.05 M NaCl solution utilizing potassium permanganate as a potential corrosion inhibitor. The microstructure of the alloys was analyzed by scanning

Nanocatalytic medicine is an emerging and promising field involving catalysis, medicine and nanotechnology, displaying inimitable advantages over traditional drug therapeutics and imaging agents.

Photocatalysis has been regarded as “21st century dream technology” and inspired increasing scientific interest due to their environmental and economic applicability. Due to the bottlenecks of photocatalytic materials (PMs) faced, such as low carrier separation efficiency, insufficient active sites, and incompatibility between surface interface properties and targeted reaction, restricting its advance

Capacity decay due to vanadium cross-over is a key technical challenge for Vanadium Redox Flow Batteries (VRFBs). To mitigate this effect this study investigates an operating strategy based on the imbalance of electrolyte solutions State of Charge (SoC). The strategy was conceived starting from the analysis of a VRFB during charge-discharge cycles adopting through-plate Reference Hydrogen Electrodes

Layered double hydroxides (LDHs), as a typical inorganic two-dimensional layered material, have been widely studied in the fields of photoelectrocatalysis, energy, and environment due to their unique layered structure and excellent catalytic activity. In addition, the flexible and adjustable laminate composition of LDHs, the flexible anion exchange and column-supported exfoliation of the domain-limited

As an important industrial enzyme, chymosin has been widely used in cheese manufacturing. Fermentation with Kluyveromyces lactis has allowed recombinant chymosin production to fit the growing global demand for cheese consumption; yet improvements can be made to allow for stable and larger-scale production. In this work, various chymosin producing (CP) strains were constructed via targeted chromosomal

Manganese oxide(MnOx) with an ultra-high theoretical specific capacitance is a prospective material for supercapacitors. However, the poor conductivity degrades the capacitive performance of MnOx. Herein, MnOx/carbon cloth (MnOx/CC) with a porous structure and mixed valence was in-situ prepared by an electrodeposition-electrooxidation method. The loose and porous lamellar structure of MnOx/CC-R(V6T4800)-O(V2T1600)

This study investigates the effects of ozone pre-treatment on two types of organic wastes: secondary sludge (SS) and wine vinasse (WV). Ozone pre-treatment of SS, a semi-solid waste, significantly increased the Dissolved Organic Carbon (DOC) and Total Volatile Fatty Acids (TVFAs) through hydrolysis. Conversely, ozone pre-treatment of WV, a liquid organic waste, reduced the availability of soluble biodegradable

A short heat treatment (HT, 90 °C–100 °C, 5 min) was applied to two-phase anaerobic digestion (TPAD) of pig manure (PM) to investigate its effect on microbial inactivation in the acidified feedstock during the methanogenic phase.
