Automation of Vertical Roller Mill for Bentonite Grinding

International Journal For Multidisciplinary Research
Bentonite is a key raw material in the production of Iron Ore Pellet making [1], where it is used as a binder. It is typically available in the form of solid lumpy mass. To utilize Bentonite in iron ore pellet production, it must be ground to fine powder. At Rungta Mines Ltd. Dhenkanal Steel Plant (RML-DSP), this grinding process is carried out using a

CO2‐to‐CO Conversion in a Gas‐Fed, Zero‐Gap, PEM Electrolyzer Enabled by Polycations and Nitrogen‐Doped Carbon‐Supported Cobalt Nanoparticles

Advanced Functional Materials, EarlyView.
A gas‐fed, zero‐gap, PEM CO2 electrolyzer is realized by incorporating PDDA+ ions onto the carbonaceous Co/N‐C electrocatalyst, with gaseous H2 and CO2 fed into the anode and cathode, respectively. Operating without an aqueous electrolyte, the system sustains a peak FECO of 65.1% at 100 mA cm−2. ABSTRACT Electrochemical carbon dioxide reduction (ECO2R)

A Magneto‐Mechanically Activated Nerve Guidance Conduit Promotes Peripheral Nerve Regeneration via TIMP1‐Mediated Membrane Tension Transfer

Advanced Functional Materials, EarlyView.
This study presents a magneto‐mechanical strategy that incorporates FP@MSCs into an aligned PCL/GelMA nerve guidance conduit. Magnetic stimulation increases membrane tension in FP@MSCs, triggering cytoskeletal remodeling, Schwann cell‐like differentiation, and TIMP1 secretion. TIMP1 activates ITGB1/CD63–FAK signaling in NE‐4C cells, increasing membrane

Unexpected Asymmetric Mn‐Sb Site Mixing and Reentrant Spin‐Glass State of MnSb2Te4

Advanced Functional Materials, EarlyView.
MnSb2Te4 is an intrinsic magnetic topological insulator. Its properties are extraordinarily sensitive to tiny defects, making structural studies essential for understanding how magnetism and topology work together. This work shows that Mn can be unevenly distributed within the crystal and how that disorder is linked to a newly reported spin‐glass state

Effect of Operating Parameters on Product Fineness Under Two-Sided Impact of Counter-Moving Grinding Media

Applied Sciences
Fine grinding is often associated with high energy consumption, and the choice of operating parameters has a direct effect on product fineness. This study examines dry particle size reduction under the two-sided impact of counter-moving grinding media. A

Formation of Vertical Pattern on Grinding Surface in High-Speed Reciprocation Profile Grinding (Continued report)

Journal of the Japan Society for Precision Engineering, 2003
This paper deals with the surface topography and grinding mark on the surface, which is ground by high-speed reciprocation grinder. The vibration of the wheel spindle forms the grinding mark. Therefore, the imbalance of grinding wheel, which causes the vibration, should be eliminated.

Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation

Advanced Functional Materials, EarlyView.
Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.
