4D‐Printed Magneto‐Plasmonic Microrobots for Programmable Spatiotemporal De‐Icing

open access: yesAdvanced Functional Materials, EarlyView.
A 4D‐printing strategy is introduced to achieve programmable de‐icing devices. By aligning gold–magnetite nanofillers within a photosensitive resin, the printed structures exhibit dual magnetic and plasmonic functionalities, enabling precise spatio‐temporal ice removal through thermoplasmonic effects.

Synthesis and properties of mixed iron and bismuth vanadates [PDF]

open access: yes, 2014
The solvothermal method for the synthesis of mixed iron and bismuth vanadates was proposed. Physicochemical properties of the obtained samples: oil absorption, pH of the aqueous extract, particle size, density, – were determined. Electrochemical studies

Metal–Organic Frameworks for Gaseous Pollutant Management: From Capture to Neutralization and Reutilization

open access: yesAdvanced Functional Materials, EarlyView.
This review maps how MOFs can manage hazardous gases by combining adsorption, neutralization, and reutilization, enabling sustainable air‐pollution control. Covering chemical warfare agent simulants, SO2, NOx, NH3, H2S, and volatile organic compounds, it highlights structure‐guided strategies that boost selectivity, water tolerance, and cycling ...

Imports as a Cause of Injury: The Case of the U.S. Steel Industry [PDF]

open access: yes
Recently, the United States International Trade Commission conducted a Section 201 or "escape clause" hearing to determine whether imports have been the most significant cause of injury to the U.S. steel industry.

Where Most Frameworks Degrade: Flexible Bimetallic Phosphonate Crystals as pH‐Universal Supercapacitor Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Plastically flexible single crystals of the bimetallic phosphonate framework [Cu(2,2′‐bpy)VO(O3PC6H5)2] combine mechanical adaptability with robust pseudocapacitive charge storage. The material delivers about 140 Fg−1 at pH 4 and pH 10 and remains stable across pH 2‐12, enabling energy storage under comparatively mild electrolyte conditions.

Uji Karakteristik Sponge Iron Hasil Reduksi Menggunakan Burner Las Asitelin Dari Pasir Besi Pantai Asemdoyong Pemalang [PDF]

open access: yes, 2015
Iron sand is sand deposits containing particles of iron ore (magnetite) found along the coast. Sponge iron is obtained from direct reduction of iron ore at a temperature below its melting point, using natural gas or gas reductant of coal or solid ...

The Floor‐Ceiling‐Chip, or 2 × 2D = Pseudo‐3D—Approaching 3D Cell Morphology and Organization between Two Opposing 2D Substrates with Cell‐Adhesive Protein Micropatterns

open access: yesAdvanced Healthcare Materials, EarlyView.
Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...

The Eighth Vibration. Asmara and Dek’emhare, Cities of Work, Cities of Leisure [PDF]

open access: yesDiacronie. Studi di Storia Contemporanea, 2015
The case of Asmara was emblematic. In 1934 Asmara had a population of about 3,500 Italians and 12,000 Africans. In 1939 Italians had risen to 48,000 whilst Africans were 36,000.

Targeting the ARRDC3–DRP1 Axis via hUMSC‐Derived Exosomal CRYAB for Neuroprotection in Cerebral Ischemia/Reperfusion Injury

open access: yesAdvanced Healthcare Materials, EarlyView.
Intranasally administered hUMSC‐derived exosomes modulate the CRYAB–ARRDC3–Drp1 axis, alleviating mitochondrial dysfunction and ferroptosis, enhancing neuronal survival, reducing oxidative stress, and promoting functional recovery in ischemia‐reperfusion injury, offering a promising therapeutic strategy for ischemic stroke.
