Resolving the Nanostructure of Carbon Nitride‐Supported Single‐Atom Catalysts

Small, EarlyView.
This study investigates the nanostructure of Ni‐based single‐atom catalysts supported on carbon nitride. By combining synthesis, advanced characterizations, and DFT calculations, the study reveals a new architecture for the nickel active sites, challenging previous models.

Facile Preparation of Carbon Nanotube‐Based Skin‐Like Pressure Sensors

Small, EarlyView.
This work demonstrates the use of a conjugated polymer with a self‐immolative linker on the sidechain as an intermediate to first enhance solution processability of single‐walled carbon nanotubes (SWNT), then generate low‐resistance SWNT materials upon sidechain removal.

Localized Microrobotic Delivery of Enzyme‐Responsive Hydrogel‐Immobilized Therapeutics to Suppress Triple‐Negative Breast Cancer

Small, EarlyView.
In response to enzymatic activity within the tumor microenvironment, remotely actuated microrobots designed for localized delivery of stimuli‐responsive hydrogels engineered to release chemotherapeutics (ChemoBots) are developed. The system leverages magnetic navigation for targeted localization and prolongsed drug release, achieving marked tumor ...

Evaluation of Alternative Lithium Salts for High‐Voltage Lithium Ion Batteries: Higher Relevance of Plated Li Morphology Than the Amount of Electrode Crosstalk

Small, EarlyView.
High voltage (>4.5 V) LiNixCoyMnzO2 (NCM)||graphite cells show rollover failure in the course of electrode crosstalk, i.e., transition metal (TM) dissolution from NCM and deposition on graphite. Interestingly, oxidatively less stable Li salts enhance the cycle life despite higher electrode crosstalk, as the morphology of plated Li has a lower surface ...

Numerical Modeling of Direct Current Plasma Versus Natural Gas‐Heated Steelmaking Ladles: Validation via Full‐Scale Industrial Measurements

steel research international, EarlyView.
This study explores using DC plasma torches with nitrogen as a carrier gas for preheating large steelmaking ladles. Numerical models simulate ladles preheated by 0.7 and 1.5 MW plasma torches, compared to natural gas heating. Results show plasma torches achieve significantly higher bottom temperatures, validated by industrial measurements on full‐sized

An Accuracy Comparison of Minimally Invasive Transclavicular‐Transcortical Drilling with Free‐Hand, C‐Shape and Assembly‐Type Guide Device: An In Vitro Study

Orthopaedic Surgery, Volume 14, Issue 12, Page 3390-3399, December 2022., 2022
The assembly guide device designed in our study could accurately locate the tunnel path. The concentric circle sliding arc was designed to make the guiding angle adjustable and matching the various drilling angles. The center of the concentric arc coincides with the midpoint of the hook, which could ensure the preset tunnel path pass through the ...

Reduction of Basic Iron Ore Sinter under Blast Furnace Wall and Center‐Simulated Conditions in CO–CO2–H2–H2O–N2 Gas

steel research international, EarlyView.
This study investigates the reduction of iron ore sinter in hydrogen and water vapor‐containing gas. It reveals differences in reduction behavior between blast furnace center and wall regions. Results highlight the role of temperature, gas composition, and microstructure in reduction efficiency.

Solid‐State Synthesis of Phase‐Pure Micron‐Sized Patrónite Vanadium Tetrasulfide toward Practical Magnesium Batteries

Small Structures, EarlyView.
An upscalable solid‐state approach is refined to obtain phase‐pure vanadium tetrasulfide (VS4), a promising magnesium battery cathode material. After optimization of the cathode processing and electrolyte formulation, the simultaneous cationic and anionic redox principle, enabling fast diffusion within VS4, is confirmed by theorical computations and ...

Europe's contribution to the evaluation of the use of systemic antimicrobials in the treatment of periodontitis

Periodontology 2000, EarlyView., 2023
Abstract This narrative review celebrates Europe's contribution to the current knowledge on systemically administered antimicrobials in periodontal treatment. Periodontitis is the most frequent chronic noncommunicable human disease. It is caused by dysbiotic bacterial biofilms and is commonly treated with subgingival instrumentation.
