Using Industrial Mining Solid Waste through Conversion to Phase-Change Materials for Thermal Energy Storage.

The mining industry produces a large amount of industrial solid waste every year. Among them, fly ash (FA), slag and tailings are the three main solid wastes, which can cause soil pollution, air pollution, water pollution and serious threat to human health if not handled properly. At present, the treatment methods of industrial solid waste mainly include direct landfill, recovery of high-value components, production of construction materials, etc.

Facile Ester-based Phase Change Materials Synthesis for Enhanced Energy Storage Toward Battery Thermal Management.

With the increasing demand for thermal management, phase change materials (PCMs) have garnered widespread attention due to their unique advantages in energy storage and temperature regulation. However, traditional PCMs present challenges in modification, with commonly used physical methods facing stability and compatibility issues. This study introduces a simple and effective chemical method by synthesizing seven ester-based PCMs through chemical reactions involving lauric acid (LA) and seven different alcohols.

Comparative genomics analysis of the reason for C heavy-ion irradiation in improving FeO nanoparticle yield of Acidithiobacillus ferrooxidans.

The FeO nanoparticle synthesized by Acidithiobacillus ferrooxidans have a broad practical value, while the low yield limits their commercial application. Herein, we employed a C heavy-ion beam to induce mutagenesis of A. ferrooxidans BYM and successfully screened a mutant BYMT-200 with a 1.

Establishment of a CRISPR-Based Lentiviral Activation Library for Transcription Factor Screening in Porcine Cells.

Transcription factors play important roles in the growth and development of various tissues in pigs, such as muscle, fat, and bone. A transcription-factor-scale activation library based on the clustered, regularly interspaced, short palindromic repeat (CRISPR)/CRISPR-associated endonuclease Cas9 (Cas9) system could facilitate the discovery and functional characterization of the transcription genes involved in a specific gene network. Here, we have designed and constructed a CRISPR activation (CRISPRa) sgRNA library, containing 5056 sgRNAs targeting the promoter region of 1264 transcription factors in pigs.

Reproducibility and repeatability of 18F-(2S, 4R)-4-fluoroglutamine PET imaging in preclinical oncology models.

Introduction: Measurement of repeatability and reproducibility (R&R) is necessary to realize the full potential of positron emission tomography (PET). Several studies have evaluated the reproducibility of PET using 18F-FDG, the most common PET tracer used in oncology, but similar studies using other PET tracers are scarce. Even fewer assess agreement and R&R with statistical methods designed explicitly for the task.
