Ammonium Salts as Curing Agents to Obtain Ionic Epoxy Resins With a Thermoplastic‐to‐Thermoset Transition

open access: yesAdvanced Materials, EarlyView.
Ionic epoxy networks are prepared using ammonium salts as hardeners, leading to a two‐stage curing process with a thermoplastic‐like intermediate. This uncommon behavior enables extrusion and fabrication of thermoplastic prepregs that can be cured into thermoset composites.

Measurement of Evaporation from Salt Water Pan

open access: yesPapers in Meteorology and Geophysics, 1980
信頼できる蒸発量の測定は気象をはじめ、多くの科学分野で重要である。世界の気象観測業務では一日間の蒸発量をクラスAパンなどの大型蒸発計を使って測定しているところが多い。この場合、蒸発量は皿の中の水深をフックゲージで測定して求めている。そのため、風が測定に影響を及ぼすし、とくに短時間の少ない蒸発量はこの方法では求めることは出来ない。 最近、塩分測定技術が電気伝導度法を用いることによって改良され、0.003‰の精度で塩分濃度を測定できるようになった。そこで電気伝導度法を用いた塩分測定技術を応用して短時間の蒸発量でも正確に測定し得る方法をここで提案する。この方法の検討結果は以下の通りである。 この方法による蒸発量測定の相対誤差は約2.5%以下にすることができる。標本抽出誤差は4×10-4‰以下であり ...

Using Intermediate-Luminosity Optical Transients (ILOTs) to reveal extended extra-solar Kuiper belt objects

open access: yes, 2016
We suggest that in the rare case of an Intermediate-Luminosity Optical Transient (ILOTs) event, evaporation of extra-solar Kuiper belt objects (ExtraKBOs) at distances of d ~ 500 - 10000AU from the ILOT can be detected. If the ILOT lasts for 1 month to a

A Solid State Zwitterionic Plastic Crystal With High Static Dielectric Constant

open access: yesAdvanced Materials, EarlyView.
Developing solid high dielectric constant materials has been a research focus in the energy storage field. In this research, we discovered a zwitterion with a plastic crystal phase. Due to the short‐range degree of freedom of the dipole moment for this zwitterion, a relatively high static dielectric constant has been achieved in its solid state ...

Remote‐Controllable Immune‐Priming Spot Formation Via Nanocomplexed Hydrogel‐Assisted Histotripsy: Immunoasis

open access: yesAdvanced Materials, EarlyView.
A novel immunotherapeutic strategy combines injectable, adjuvant‐loaded hydrogels with externally controlled histotripsy to create immune‐priming sites within tumors. This approach generates millimeter‐sized immune‐activated lesions with flexible, patient‐tailored treatment scheduling, enabling precise immune activation through tumor ablation‐mediated ...

Meteorological Factors Affecting Pan Evaporation in the Haihe River Basin, China

open access: yesWater, 2019
Pan evaporation (Epan) is an important indicator of regional evaporation intensity and degree of drought. However, although more evaporation is expected under rising temperatures, the reverse trend has been observed in many parts of the world, known as ...
