A Miniature Rotary Electrostatic Clutch for Assigning Multi‐Degrees of Freedom to Insect‐Scale Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
Insect‐scale crawling robots can traverse confined environments; nevertheless, their functionalities are predominantly restricted to sensing because of challenges in integrating actuated degrees of freedom. Herein, a miniature rotary electrostatic clutch is presented by incorporating cutting patterns in the clutch layer.

A Multimodal Laser‐Induced Graphene‐Based Flexible Sensor for Soft Robotic Hand Environmental Perception

open access: yesAdvanced Intelligent Systems, EarlyView.
A multimodal laser‐induced graphene (LIG)‐based flexible sensor is developed to detect proximity and contact signals. Integrated into a soft robotic hand, it enables vision‐free object searching and grasping. Combined with a convolutional neural network, the system achieves accurate material and texture recognition, enhancing the capability of ...

THE PHENOMENON OF PVC FILM DEFORMATION, NAMELY WAVINESS OF PVC FILM CAUSED BETWEEN TWO SOFT PVC FILMS FORMED BY DIFFERENT COMPOUNDS. CHAPTER I INFLUENCE OF RAW MATERIALS

open access: yesNIPPON GOMU KYOKAISHI, 1965
異種配合の軟質塩化ビニルフィルム二層間において起る変形現象について物理的な影響を観察し次の知見をえた.1) フィルムの厚みの影響.シートと同種の可塑剤 (DOP) の場合, 厚みの影響はほとんどあらわれていないが, DBPの場合はフィルムの厚みが厚いほどDBPの移行は少なくなっている.2) 塩化ビニル樹脂に他の樹脂をブレンドした場合, 市販品の各樹脂をブレンドしたが, 30%以下のブレンドでは, ほとんど効果がなかった.3) 二枚の塩化ビニルフィルム (またはシート) 問に異種の樹脂フィルム各種をそれぞれ挿入した場合, 0.03mm程度のフィルムの挿入ではほとんど効果はなかった.4) 塩化ビニルフィルムの加工条件の差.加工条件はかえてみても一定の傾向はえられなかった.

Evaluating the Impact of Cellulose Nanocrystals on the Performance of Polycarbonate Thin‐Film Nanocomposite Membranes for Treating Oily Wastewater

open access: yesAsia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A new type of thin‐film nanocomposite (TFN) membrane was synthesized by incorporating cellulose nanocrystals (CNCs) into a polyvinyl alcohol (PVA) top layer on a polycarbonate (PC) substrate via dip‐coating. The synthesized TFC and TFN membranes (PC/PVA TFC and PC/PVA‐CNC TFN membranes) were evaluated using contact angle measurement, field ...

Surfactant‐Enhanced Electrospun Nanofiber Filters for Efficient Viral and Bacterial Inactivation

open access: yesJournal of Applied Polymer Science, EarlyView.
In this work, electrospun polyacrylonitrile (PAN) nanofibrous filters functionalized with surfactants (CTAB, CPC, and SDS) were developed for air filtration applications. The PAN nanofiber mats enable efficient particulate matter capture while simultaneously providing antimicrobial and antiviral activity against bacteria (E. coli and S.
