NHC-Boranes: Air- and Water-tolerant Co-initiators for Type II Photopolymerizations
N-Hetereocyclic carbene (NHC) complexes of boranes are stable compounds that can be used as co-initiators for the type II photopolymerization of acrylates.

Liquid Crystal Elastomer Actuator Matrix for Large Area Applications
A scalable approach is used to manufacture a digitally‐controllable, 2D 5 × 5 actuator matrix. The elements of the matrix are produced by direct ink writing of a liquid crystal elastomer ‘artificial muscle’ on large‐area flexible thin‐film heaters. In optimizing the low‐power actuators, multiple heater designs and substrate materials are investigated ...

Comprehensive analysis of acrylates: industrial applications and potential health effects
Acrylates are a diverse group of chemical compounds valued for their transparency, flexibility, strength, hardness, and polymerisation capacity. They are widely used in medicine, dentistry, ophthalmic devices, antimicrobial materials, tissue engineering,

Microscale 3D‐Printed Digital Strain Switches for Embedded Mechanical Computation
Microscale 3D‐printed strain switches on flexible films convert deformation into native digital signals at geometry defined thresholds. A closed form model predicts switching from 3000 to 15 000 microstrain and is validated across 110 devices. Reliable ohmic closure and strain activated AND, OR, and XOR logic point toward low‐power mechanical ...

Metal-organic frameworks (MOFs) have emerged as exceptional materials for atmospheric water harvesting (AWH) due to their superior adsorption properties in low humidity conditions (≤ 20% RH), but most MOF adsorbents typically exist in powder form, thus ...

グリセリン浴およびエチレングリコール浴で紡糸したアクリル繊維未延伸糸を延伸し, 延伸による強伸度, 密度, X線による配向度および側間規則性, 顕微鏡による断面形状などの変化を調べた。1) エチレングリコール浴で紡糸した未延伸糸の密度は著しく小さい。延伸によってその密度は増加するが, 4倍以上の延伸ではその増加の程度が少ない。グリセリン浴で紡糸した未延伸糸の密度は大きく, 延伸による変化はほとんどない。2) 延伸によって強度および初期弾性率は大きくなるが, 同一延伸倍率ではグリセリン浴で紡糸した糸を用いた場合の方がこれらの値は大きく, X線的配向度も同じような傾向を示している.このような機械的性質に対しては分子の配向が支配的な影響をもっている. 3) 延伸によって配向度および側間規則性は良くなるが,

Late patch-test reaction to acrylates: a biochemical hypothesis.
Acrylates (acrylic and methacrylic compounds) are commonly used in dentistry as restorative materials, and their use is progressively increasing because of the concern for mercury-related health problems (allergic and nonallergic) due to their metal ...

Region‐specific profiling of the gut microbiome is achieved non‐invasively using electronics‐free ingestible sampling capsules that activate at defined intestinal sites through stimuli‐responsive coatings. Deployed in a porcine dietary intervention model, the capsules resolve spatially distinct, fiber‐driven shifts in microbial composition and short ...

Zero‐Waste Manufacturing of Ophthalmic Lenses by Direct Fluidic Shaping in Arbitrary Domains
Conventional ophthalmic lens manufacturing discards up to 97% of material through subtractive processes. The Cookie Cutter algorithm extends Fluidic Shaping to arbitrary rim geometries. The framework prescribes a spatially varying boundary height that, under neutral buoyancy and surface tension, shapes curable polymer into spherocylindrical lenses that
