Expenditure from provincial environmental protection and water management funds vs. pollution reduction

open access: yesRozwój Regionalny i Polityka Regionalna
The aim of this study is to examine the factors influencing changes in the emission of gaseous pollutants in the voivodeships in Poland in the years 2014–2023. The work uses the logarithmic mean method of the Divisia index, also referred to as the LMDI (

On the Capability of Logarithmic-Power Model for Prediction of Hot Deformation Behavior of Alloy 800H at High Strain Rates

open access: yesHigh Temperature Materials and Processes, 2019
In this study, the logarithmic-power model has been used to predict hot deformation behavior of alloy 800H at high temperatures. This is for the first time that the logarithmic-power model is examined to model the flow stress curves with negligible flow ...

Molecular Cross‐Linking of MXenes: Tunable Interfaces and Chemiresistive Sensing

open access: yesAdvanced Functional Materials, EarlyView.
In this study, Ti3C2Tx MXenes are initially functionalized using oleylamine ligands to form stable dispersions in an organic solvent. Subsequently ligand exchange with α,ω‐diaminoalkanes enables cross‐linking, along with precise tuning of interfaces. This structural control translates into tunable charge transport and responsive VOC sensing, showing ...

An effective and economic estimation of population mean in stratified random sampling using a linear cost function

open access: yesHeliyon
Improvement in the estimation of population mean has been an area of interest in sampling theory. So many estimators have been suggested for elevated estimation of the population mean in stratified random sampling, but there is still a gap for more ...

Single Solid‐State Ion Channels as Potentiometric Nanosensors

open access: yesAdvanced Functional Materials, EarlyView.
Single gold nanopores functionalized with mixed self‐assembled monolayers act as solid‐state ion channels for direct, selective potentiometric sensing of inorganic ions (Ag⁺). The design overcomes key miniaturization barriers of conventional ion‐selective electrodes by combining low resistivity with suppressed loss of active components, enabling robust

On Some Cauchy Type Mean-Value Theorems with Applications

open access: yesCommunications in Advanced Mathematical Sciences
Some Cauchy-type mean-value theorems for Chebychev’s inequality, Steffensen’s inequality, midpoint rule, and Simpson’s rule are presented. Furthermore, we give some applications for the obtained results using the exponential and logarithmic functions ...

Endothelial Cells Angiogenesis in Sulfated Glycosaminoglycan (GAG) Hydrogels Enhanced by Bioactive Glass‐Released Ions

open access: yesAdvanced Functional Materials, EarlyView.
A mechanically tunable hydrogel composed of gelatin, chondroitin sulfate and laminin promotes angiogenesis in vitro without the supplement of growth factors. Endothelial cells morphogenesis was further enhanced by medium conditioned with bioactive glass 58S‐released ions (Ca and Si), thus offering a promising strategy to vascularize 3D tissue ...

The Effect of Amino Acids on the Formation of Amorphous Calcium Carbonate Nanoparticles

open access: yesAdvanced Functional Materials, EarlyView.
Biomineral formation often proceeds via the assembly of amorphous calcium carbonate (ACC) nanoparticles with narrow size distributions. Using in situ SAXS coupled to a stopped‐flow device, we follow synthetic ACC formation with a 10 ms time resolution and show that amino acids narrow the size distribution at low supersaturation, highlighting their key ...

Dual‐Functional Li2B4O7 Coating on Carbon Fibers for Enhanced Li+ Transport and Stability in Sulfide All‐Solid‐State Batteries

open access: yesAdvanced Functional Materials, EarlyView.
A dual‐functional Li2B4O7 coating on carbon fibers is designed to resolve the critical interfacial degradation in sulfide all‐solid‐state batteries. The conformal layer acts as a physical barrier to suppress parasitic reactions while its unique dielectric properties simultaneously facilitate Li+ transport.
