Make‐Use‐Remake: Toward Indefinite Low‐Temperature Material Loops

Advanced Functional Materials, EarlyView.
We introduce a regenerable materials platform built from microparticles bound by a temperature‐responsive polymer shell, enabling strong, processable structures from diverse feedstocks. The material is shaped at low temperatures (80°C) using common manufacturing methods and reprocessed repeatedly in the presence of water, demonstrating stable ...

Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, EarlyView.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

Sand Burning in Ceramic Sand Mold for Iron and Steel Casting [PDF]

Journal of the Korea Foundry Society, 2011
3.1 Al2O3 및 SiO2의 영향 Fig. 1의 Al2O3-SiO2계 평형상태도에 의하면 0% < Al2O3< 71.8% 범위의 조성범위에서 1597C가 공융점으로, 이 온도 이 상에서는 융액을 생성하기 시작한다. 71.8wt% < Al2O3< 100wt%의 조성범위에서의 공융점은 1843 C 로 이 온도 이하에서는 융액을 생성하지 않고 뮬라이트와 코 런덤이 안정적으로 존재한다. 그러나 실제 열간하중연화온도는 이 온도보다 500C 이상 낮아질 수 있으므로 주의를 해야 한다. 다음은 세라믹샌드의 불순물 특히, 알칼리에 의한 영향을 기 술하고자 한다. 3.2 Na2O의 영향 Al2O3-SiO2계 내화물은 1597 C까지 액상을

Iron anode mediated transformation of selenate in sand columns [PDF]

Water Research, 2013
Removal of aqueous selenate by iron electrolysis is investigated using sand-packed column experiments under a flowing condition. An iron anode generates ferrous ions, while cathode produces hydroxide, thus producing ferrous hydroxide capable of reducing selenate to elemental selenium.

Material Before Morphology: Substrate‐Dependent Mechanical Tuning of Radular Teeth

Advanced Materials Interfaces, EarlyView.
Substrate‐dependent material tuning in Clausilia radular teeth. Closely related taxa retain a conserved gross tooth morphology, but differ in elemental composition and mechanical properties according to feeding substrate. Rock‐associated taxa show increased Ca–Si enrichment and higher stiffness and hardness, especially in the central radular region ...

Coating‐Free Nanoscratching for Liquid‐Crystal Alignment on PCB‐Compatible Millimeter‐Wave Reflective Unit Cells

Advanced Materials Technologies, EarlyView.
Direct nanoscratching with a 500 nm diamond lapping film creates groove‐guided liquid‐crystal alignment interfaces on PCB‐compatible Cu‐patterned RF substrates within minutes, eliminating polymer coating and high‐temperature baking. The coating‐free process enables optical/molecular alignment validation and voltage‐programmable 28 GHz reflection‐phase ...
