Superlubricity and Corrosion Inhibition Properties of Solvate Ionic Liquids in Hybrid Carbon Fiber Reinforced Plastic–Steel Interfaces

open access: yesAdvanced Engineering Materials, EarlyView.
Solvate ionic liquids lubrication reduced the coefficient of friction by ∼60% compared to dry sliding, reaching steady‐state values as low as 0.04–0.05. Corrosion weight‐loss measurements in 1 M HCl further demonstrated significant inhibition behavior, with only 100 ppm of [Li(G3)][TFSI] (∼68.5 μL/L) reducing corrosion‐product weight loss by 63 ...

Chondroid Syringoma: A Rare Lower Lid Tumor

open access: yesDelhi Journal of Ophthalmology
Chondroid syringoma is a very rare primary skin tumor that accounts for just 0.01%–0.1% of all skin malignancies. Although it is highly common in the head-and-neck region, eyelid involvement is extremely unusual.

FastNano Liquid: An Automated Platform for Small‐Angle X‐ray Scattering‐Based Materials Discovery

open access: yesAdvanced Engineering Materials, EarlyView.
We present FastNano Liquid, an automated small‐ and wide‐angle X‐ray scattering platform for the combined synthesis and characterization of (nano)materials. The platform is coupled to varied reactor workflows for both in situ studies of reaction kinetics and ex situ screening of synthesis conditions to support machine learning‐guided exploration ...

High‐Speed Photoresponse of CVD‐Grown Lateral TMD Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
Internal electric fields generated by p‐n junctions and asymmetric Schottky barriers enhance the photoresponse speed in CVD‐grown monolayer TMD lateral heterostructures. This results in a 1.5‐2 orders of magnitude reduction in rise and fall times for optimized device configurations compared to homogeneous single‐material devices, enabling bandwidths ...

شبیه‌سازی رواناب سطحی شهری و اولویت‌بندی روش‌های توسعه‌کم‌اثر با استفاده از مدل SWMM (مطالعه موردی: شهر نیشابور) [PDF]

open access: yesمدیریت آب و آبیاری
اخیرا تغییر خصوصیات هیدرولوژیک و پاسخ حوضه شهری نسبت به بارش و سیلاب‌ها از نظر کمی و کیفی در زندگی بشر و منابع مشهودتر شده است. جلوگیری از اتلاف این هرزآب‌ها و به تبع آن جبران کمبود منابع‌آبی،‌ گامی موثر در این خصوص است.

Distinct Cytokine Profiles Correlate with Disease Severity and Outcome in Longitudinal Studies of Acute Hepatitis B Virus and Hepatitis D Virus Infection in Chimpanzees

open access: yesmBio, 2020
Historical studies conducted in chimpanzees gave us the opportunity to investigate the basis for the different severities of liver damage and disease outcome associated with infection with wild-type hepatitis B virus (HBV) versus a precore HBV mutant ...

An Integrated Oxygen‐Supplying Device and Predictive Multiphysics Model for Extended Ambient Transport of Insulin‐Producing Cells

open access: yesAdvanced Functional Materials, EarlyView.
Cell therapies typically rely on cold‐chain logistics and cryopreservation, limiting access and compromising cell quality. Here, a dual‐chamber device separates an oxygen‐supplying chamber from a hyaluronic acid cargo chamber, sustaining oxygen delivery for over 70 h and enabling ambient‐temperature shipment.

ATP‐Mediated Bidirectional Communication Between Natural and Artificial Cells for Controlled Bioreactions

open access: yesAdvanced Functional Materials, EarlyView.
Establishment of bidirectional communication behavior between natural and artificial cells. The first type of communication from natural dendritic cells to artificial polymeric cells was achieved via ATP release after cell lysis. The released ATP was taken up via gated UV‐controlled permeability increase of the polymeric membrane for performing ...
