The evolution of mine waters quality at the locality of Smolník [PDF]
Acta Montanistica Slovaca, 2006 At the present time, acid mine drainage (AMD) is considered to be one of the worst environmental problems associated with the mining activity. AMD originates as a result of natural oxidation of sulphide minerals, mainly pyrite when exposed to the ...

Mechanisms of IgE‐mediated food allergy and the role of allergen‐specific B cells
FEBS Letters, EarlyView.Food allergy arises when allergen‐specific B cells preferentially produce immunoglobulin E (IgE) antibodies against harmless foods. This article explains the mechanisms driving IgE‐mediated reactions, highlights the central role of these B cells, and discusses how natural tolerance (NT) and oral immunotherapy (OIT) can reshape allergic immune responses.

Advanced Functional Materials, EarlyView.Edible electronics needs integrated logic circuits for computation and control. This work presents a potentially edible printed chitosan‐gated transistor with a design optimized for integration in circuits. Its implementation in integrated logic gates and circuits operating at low voltage (0.7 V) is demonstrated, as well as the compatibility with an ...

Advanced Functional Materials, EarlyView.A bimetallic Mn–Ca nanoreactor (MCC) is developed as a non‐nucleotide STING nanoagonist for cancer metalloimmunotherapy. MCC induces Ca2+ overload and hydroxyl radical generation, resulting in mitochondrial damage and mtDNA release. The released mtDNA cooperates with Mn2+ to robustly activate cGAS–STING signaling.

Alkali Ion‐Incorporated HfO2 Dielectrics for Reconfigurable Neuromorphic Computing
Advanced Functional Materials, EarlyView.This work presents an indium gallium zinc oxide (IGZO) transistor with an alkali cation‐integrated hafnium dioxide (HfO2) dielectric exhibiting synaptic behavior via ion retention. The solution‐based film fabrication strategy overcomes the limitations of atomic layer deposition (ALD) and precursor coating, enabling the control of synaptic retention ...

Advanced Functional Materials, EarlyView.A charge injection layer is introduced via RIE to decouple the dual functions of the source electrode: lowering contact resistance through doping to enhance charge injection, while SAM modification on the top surface minimizes leakage current. This strategy enables OSBTs to achieve a high on/off ratio with improved stability and performance.

Role of Histidine‐Containing Peptoids in Accelerating the Kinetics of Calcite Growth
Advanced Functional Materials, EarlyView.Amphiphilic histidine‐containing peptoids mimic carbonic anhydrase (CA) to accelerate calcite step growth. In the presence of Zn2+, they promote the deprotonation of HCO3−, the desolvation of Ca2+, and the reorganization of interfacial hydration layers, thereby reducing the activation barrier for calcite growth.
