Carbon Anodes for Low‐Temperature Nonaqueous Alkali Metal‐Ion Batteries

EcoEnergy, EarlyView.
This review summarizes recent progress in carbon anodes for low‐temperature nonaqueous alkali‐metal ion batteries. Fundamental thermodynamic and kinetic limitations are examined, alongside a systematic discussion of graphite, hard carbon, and emerging carbon architectures.

Transient Charging Dynamics in Stacked Ga2O3/ZnO Photovoltaic Units Governing Wavelength‐Selective Polarity Switching

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work reveals a “Photovoltaic‐Capacitance” coupling mechanism in stacked Ga2O3/ZnO devices, defining the ZnO/graphene interface as a novel Photovoltaic Dynamic‐Capacitor (PDC). The wavelength‐selective bipolar response enables a physical layer secure communication protocol based on ternary optical logic (“1,” “0,” “−1”).

Numerical Simulation Research on Cutting Rock with a PDC Cutter Assisted by an Impact Force

, 2022
Extensive studies have been carried out on cutting rock with a PDC cutter, but cutting rock assisted by impact force is rarely studied. In this paper, cutting rock using conical and cylindrical PDC cutters assisted by impact force were researched with ...

Human Umbilical Cord Mesenchymal Stem Cell–Derived Exosomes Attenuate Renal Fibrosis by Suppressing Fibroblast Activation via the INHBA/PI3K/AKT Pathway

Pediatric Discovery, EarlyView.
MSC‐Exo derived from human umbilical cord (HucMSC‐Exo) downregulates INHBA expression, consequently modulating the PI3K/AKT signaling cascade. This regulation attenuates renal fibroblast activation and extracellular matrix deposition, thereby exerting a renoprotective effect against fibrosis.

Allergen‐Functionalized Microfluidic Immunoadsorption Platform for Selective Depletion of Peanut‐Specific Antibodies From Whole Blood

Journal of Polymer Science, EarlyView.
We present a microfluidic immunoadsorption platform functionalized with a layer‐by‐layer (LbL) nanofilm composed of poly(diallyldimethylammonium chloride) (PDDA) and protein extract (PE) for selective capture of peanut‐specific antibodies directly from the whole blood obtained from a peanut allergy mouse model.

Universal Confinement Length Governs Radical Depolymerization Kinetics in Nanoconfined Polymers

Small, EarlyView.
Analysis of PMMA depolymerization kinetics identifies a critical threshold under extreme nanoconfinement where segmental mobility saturation prevents further increases in depolymerization temperature. ABSTRACT Thermal depolymerization is typically studied in bulk, yet many systems involve polymers confined within nanoscale geometries. Understanding how

Numerical Simulation and Field Test of a PDC Bit with Mixed Cutter Arrangement to Break Non-Homogeneous Granite

, 2023
As the depth of petroleum drilling increases, the strata environment becomes more complex. The efficiency and lifespan of Polycrystalline Diamond Compact (PDC) drill bits fail to meet current drilling demands.

Spatial Transcriptomics Identifies Characteristic Immunological Niches in Atopic Dermatitis

Allergy, EarlyView.
Spatially organized immune niches containing mature migratory dendritic cells (mmDCs) and CD4+ T cells in atopic dermatitis lesions support localized T cell activation and may contribute to disease persistence. Spatial transcriptomics identifies conserved immune niches in atopic dermatitis lesions, characterized by close co‐localization of CD4+ T cells

Study of the Cutter Design of PDC Drill Bits on Effect of Back Rake Angle and Size of the Cutter on Wear Rate [PDF]

, 2015
In the oil and gas industry, drilling is one of the most important aspects due to the economics and high demand. Reduction in drilling time is required to minimize the cost of operations.

A Real Mathematical Model to Compute the PDC Cutter Wear Value to Terminate PDC Bit Run

, 2011
Drilling operations became more expensive and complicated day by day due to many reasons affecting directly the daily drilling cost. One of the most effective cost reductions was the fixed cutter bit solution which effectively achieved higher drilling ...
