Acetaminophen (APAP) is an extensively consumed over-the-counter and prescribed medication and a constituent of many active pharmaceutical compounds as well as personal care products. Its wide-scale prevalence in the environment due to inefficient treatment technologies has classified APAP as a contaminant of emerging concern. Thus, it is imperative to explore efficient and sustainable methods for remediation of contaminated environments.

Polyetheretherketone (PEEK) is a high-performance polymer material for developing varying orthopedic, spine, cranial, maxillofacial, and dental implants. Despite their commendable mechanical properties and biocompatibility, the major limitation of PEEK implants is their low affinity to osseointegrate with the neighboring bone. Over the last two decades, several efforts have been made to incorporate bioactive components such as bioceramic particles in PEEK to enhance its osseointegration capacity.

Objective: Previous studies on muscle fibers, myofibrils, and myosin revealed that the release of inorganic phosphate (P) and the force-generating step(s) are reversible, with cross-bridges also cycling backward through these steps by reversing force-generating steps and rebinding P. The aim was to explore the significance of force redevelopment kinetics (rate constant ) in cardiac myofibrils for the coupling between the P binding induced force reversal and the rate-limiting transition for backward cycling of cross-bridges from force-generating to non-force-generating states.
Methods: and force generation of cardiac myofibrils from guinea pigs were investigated at 0.

Inorganic anions such as chloride (Cl), nitrate (), sulfate (), carbonate (), bicarbonate (), dihydrogen phosphate (), fluoride (F) are ubiquitous in water matrices, play a significant role in the degradation of organic pollutants by Fenton process. In the present study, the performance of Fenton process in the presence of these anions was studied using phenol as a model compound along with the underlying mechanism and their tolerance limit. The presence of these anions affects the rate constant of the Fenton process and decreases in the following order, ---Cl > > > > F.

The adsorption of phosphate in the collected water is crucial to alleviate the crisis of phosphorus resources, which is in line with the concept of green and sustainable development of resources. In this study, based on the calcium modification technology of pyrolysis combined with chemical modification, a new type of calcium modified coal gangue (CaMCG) was prepared by using coal gangue as raw material and calcium chloride as modifier for the removal of phosphate.The optimum preparation conditions of CaMCG were obtained by response surface test: m:m=1, calcination temperature 735℃, calcination time 135 min.
