Catalytic Deconstruction of Commercial and End-of-Life Polyurethane with Heterogeneous Hydrogenation Catalyst.

Polyurethane (PU), as a thermoset polymer, is extensively utilized in various applications, such as refrigerator foams, sponges, elastomers, shoes, etc. However, the recycling of post-consumed PU poses significant challenges due to its intricate and extensive crosslinking structures. Catalytic hydrogenation is one of the most effective methods for recycling PU waste, nevertheless, there is currently a lack for a hydrogenation catalyst that is both high-performing, recyclable, and cost-effective for breaking down post-consumed PU materials.

Catalysis pyrolysis debromination from waste printed circuit boards: Catalysts selection, parameter effects, products, and mechanisms.

As a typical e-waste, waste printed circuit boards (WPCBs), are the most valuable and hazardous components containing all the basic and precious metals as well as toxic substances such as heavy metals, brominated epoxy resins (BERs) and brominated flame retardants (BFRs). Due to their high toxicity and carcinogenicity, effective treatment of BERs and BFRs is the key to achieve the environmental-friendly recycling of WPCBs. Recently, catalysis pyrolysis has proven an efficient and promising approach to removing and recovering bromides from WPCBs.

Evaluation of the Psychometric Properties of the Translated Physical Self-Perception Profile Among Chinese Breast Cancer Survivor.

Purpose: The purpose of this study was to translate the original English version of the Physical Self-Perception Profile into Cantonese Chinese, while considering linguistic and socio-cultural characteristics, and to evaluate its psychometric properties among Chinese breast cancer survivors in Hong Kong, China, thus providing a valid, culturally relevant tool for assessing physical self-esteem among this population.

Existing evidence lacks a comprehensive review of the effectiveness of body image interventions for pregnant and postpartum women.

Ni-based catalysts supported on Hbeta zeolite for the hydrocracking of waste polyolefins.

Polyolefin plastics are the most popular polymer materials worldwide, and the catalytic degradation of post-consumer polyolefins has attracted increased attention as a viable process. In this study, two types of Ni-based catalysts supported on Hbeta zeolite, Ni-Hbeta and NiS-Hbeta, have been successfully synthesized for the hydrocracking of waste polyolefin. The experimental results indicated that the synergistic effect between Ni or NiS and the acidic sites of Hbeta zeolites can significantly enhance the tandem cracking and hydrogenation of polyolefin plastics, which suppresses the formation of gas products and coke.

Study on anionic-nonionic mixed surfactant for enhanced oil recovery in a hypersaline reservoir.

Hypersaline reservoirs are characterized by high salinity and high calcium and magnesium concentration. In order to enhance oil recovery of the hypersaline reservoirs, a specialized ternary mixed surfactant system composed of nonionic alkanolamide surfactants and anionic surfactant was developed in this study. Through careful analysis and optimization, lauric acid diethanolamide (LDEA), octanoic acid diethanolamide (ODEA), and sodium dodecyl sulfonate (SDS) were identified as promising candidates for the surfactant compounding system, and formed a ternary surfactant system composed of LDEA, ODEA, and SDS with the mass ratio of 4.

high-valued transformation of nonmetals in waste printed circuit boards into supercapacitor electrodes with excellent performance.

Nonmetals in waste printed circuit boards after metal separation containing brominated resin and fiberglass are considered hazardous and low-recoveryvalue e-waste. However, if these nonmetals are not treated or are improperly treated, they can cause serious environmental pollution. Therefore, there is an urgent and significant need to develop an efficient recycling process for these nonmetals.

Nickel Sulfide/Hierarchical Porous Carbon from Spent Residue Hydrocracking Catalyst as Electrocatalyst for the Oxygen Evolution Reaction.

Spent residue slurry-phase hydrocracking catalyst coated with coke have been classified as hazardous solid waste, presenting serious economic and environmental issues to refiners. Herein, the spent catalysts with a nickel sulfide nanoparticle/coke hierarchical structure (NiS /C) from our previous work were used to prepare nickel sulfide/hierarchical porous carbon (NiS /HPC) for the oxygen evolution reaction (OER) through the method of carbonization, activation, and sulfurization. The results indicate that the NiS /C converts into Ni/HPC after carbonization and activation, and then transform into NiS /HPC by sulfurization.

The effects of message framing on self-management behavior among people with type 2 diabetes: A randomized controlled trial.

Background: Message framing describes how information is communicated and demonstrated to influence its effect on future attitudes and behaviors. Message content can be structured as 'gain-framed', emphasizing the benefits of engagement as recommended, whereas 'loss-framed' describes the negative consequences of not engaging as recommended. However, the impact of message framing on behavior change in people with chronic diseases like diabetes is not well understood.

Effects of message framing on self-management behaviour among patients with type 2 diabetes: a randomised controlled trial protocol.

Introduction: Accumulating evidence has indicated successful diabetes health education can potentially help to improve blood sugar levels in people with diabetes. However, with a rapid rise in the number of people with diabetes cases and the increasing burden on healthcare, it is often difficult for healthcare providers to find suitable time to provide health education to meet their needs. Thus, more novel and effective ways are needed to conduct education.

In-situ debromination mechanism based on self-activation and catalysis of Ca(OH) during pyrolysis of waste printed circuit boards.

Completely and deeply removed bromide from waste printed circuit boards (WPCBs) is necessary due to their toxicity and carcinogenicity. To achieve this purpose, calcium hydroxide (Ca(OH)) as a debromination agent was added during pyrolysis process of WPCBs. The results showed that hydrogen bromide (HBr), 4-bromophenol, 2-bromophenol and 2,4-dibromophenol were the main bromide species in pyrolysis products.
