Aim: The objective of pulpotomy is to preserve the pulp vitality. However, the assessment of pulpal status following pulpotomy is often overlooked. This retrospective analysis aimed to compare the pulp responses to EPT (Electric pulp test) and cold test in mature permanent molars that have undergone either complete pulpotomy (CP) or partial pulpotomy (PP) for managing carious pulpal exposure and symptomatic irreversible pulpitis (SIP) and completed 12 months follow-up.

Harnessing ionic gradients to generate electricity has inspired the development of nanofluidic membranes with charged nanochannels for osmotic energy conversion. However, achieving high-performance osmotic energy output remains elusive due to the trade-off between ion selectivity and nanochannel membrane permeability. In this study, we report a homogeneous nanofluidic membrane, composed of sulfonated nanoporous carbon (SPC) and TEMPO-oxidized cellulose nanofibers (T-CNF), engineered to overcome these limitations.

Utilizing cellulose nanocrystals (CNCs) to mimic biological skin capable of converting external stimuli into optical and electrical signals represents a significant advancement in the development of advanced photonic materials. However, traditional CNC photonic materials typically exhibit static and singular optical properties, with their structural color and mechanical performance being susceptible to water molecules, thereby limiting their practical applications. In this study, CNC-based conductive elastomers with dynamic mechanochromism, fluorescence responsiveness, and enhanced water resistance were developed by incorporating carbon quantum dots (C QDs) and hydrophobic deep eutectic solvents (HDES) into CNC photonic films via an in-situ swelling-photopolymerization method.

The growing demand for sustainable infrastructure has increased interest in eco-friendly design solutions such as porous asphalt (PA) pavements, which manage stormwater runoff and mitigate urban heat islands, and warm mix asphalt (WMA), which reduces energy consumption and emissions during production. This study evaluates the mechanical and environmental performance of four warm mix porous asphalt (WPA) mixtures incorporating recycled materials and by-products: reclaimed asphalt pavement (RAP), aramid pulp fibres, and electric arc furnace (EAF) steel slag. A Life Cycle Assessment (LCA) with a cradle-to-cradle approach was conducted to comprehensively assess environmental impacts.
