Design of a Novel Polyvinyl Imidazole-Based Adsorbent for Efficient Textile Dye Removal

open access: yesNanomaterials
Textile dye effluents containing toxic organic compounds pose serious environmental challenges. In this study, novel Poly(1-vinyl imidazole)-Bis[2-(methacryloyloxy)ethyl] phosphate (PVIB) polymers were synthesized with crosslinker molar fractions ranging

Food Tastes in the United States: Convergence or Divergence?

open access: yesAgribusiness, EarlyView.
ABSTRACT This study investigates how food consumption tastes have changed in recent decades across the United States. Using NielsenIQ data for over 77 million transactions, there is evidence of divergence in food tastes across regions from 2007 to 2016 and across households of different income, education, and race/ethnicity groups.

Instability mechanism and failure characteristics of underground cavern in block system under the action of seismic waves

open access: yesDeep Underground Science and Engineering, EarlyView.
Seismic waves with tensile stress, high amplitude, and low frequency are most likely to trigger block instability and sliding. Blocks with a single sliding surface are more prone to movement than those with multiple constraints, and roof‐positioned blocks are especially vulnerable to slide.

Dual‐Phase In Situ Symbiosis Structures for Ultrahigh Capacitive Energy Storage

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A dual‐phase in situ symbiosis structure designed by introducing a linear‐like pyrochlore phase (P phase) into the ferroelectric Aurivillius phase (A phase) and precisely controlling its proportion provides a new strategy for optimizing dielectric energy storage.

Ancestral Sequence Reconstruction Enhances Thermal Stability of D-Allulose 3-Epimerase

open access: yesShipin gongye ke-ji
To solve the problem of poor thermal stability of the current D-allulose 3-epimerase (DAEase), the ancestor sequences of DAEase with different catalytic domains were reconstructed by big data mining, reasonable modification and ancestor sequence ...

Central tetrads and quantum spacetimes

open access: yes, 2016
In this paper, we perform a parallel analysis to the model proposed in [25]. By considering the central co-tetrad (instead of the central metric), we investigate the modifications in the gravitational metrics coming from the noncommutative spacetime of ...

Causal correlations between inflammatory proteins and heart failure: A two‐sample Mendelian randomization analysis

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1374-1385, April 2025.
Abstract Aims Inflammation plays a critical role in both the development and progression of heart failure (HF), which is a leading cause of morbidity and mortality worldwide. However, the causality between specific inflammation‐related proteins and HF risk remains unclear.
