Scalable Upcycling of Spent Lithium‐Ion Battery Anodic Graphite to Electronic‐Grade Graphene

Advanced Science, EarlyView.
Graphite anodes from spent lithium‐ion batteries are upcycled into electronic‐grade graphene nanoplatelets for highly conductive screen printing inks (> 104 S m−1). Screen‐printed micro‐supercapacitors confirm the utility of the upcycled graphene (1.78 mF/cm2 capacitance for > 10 000 cycles). Life cycle assessment and techno‐economic analysis highlight

Mechanism of Contact between a Droplet and an Atomically Smooth Substrate

, 2017
When a droplet gently lands on an atomically smooth substrate, it will most likely contact the underlying surface in about 0.1 s. However, theoretical estimation from fluid mechanics predicts a contact time of 10 to 100 s.

Anorectal profilometry with the microtransducer

Journal of British Surgery, 1984
Abstract The reproducibility of anal sphincter manometry has been evaluated in 17 patients with a continuous pull-through technique using a miniature transducer mounted on a 2mm diameter Dacron catheter. Comparison was made with a conventional station pull-through technique using a 4mm diameter waterfilled microballoon connected to an ...

Solution‐Shearing of Highly Smooth Ion‐Gel Thin Films: Facilitating the Deposition of Organic Semiconductors for Ion‐Gated Organic Field Effect Transistors

Advanced Electronic Materials, Volume 11, Issue 6, May 2025.
A straightforward method is introduced to produce ion‐gel films with very low surface roughness by employing a solution‐shearing coating process. These ion‐gel films permit the growth of crystalline thin films of various small molecule organic semiconductor molecules directly on top of the ion‐gel layer, thereby enabling “inverted” small molecule ...

Laser interferometric measurement of ion electrode shape and charge exchange erosion [PDF]

A projected fringe profilometry system was applied to surface contour measurements of an accelerator electrode from an ion thrustor. The system permitted noncontact, nondestructive evaluation of the fine and gross structure of the electrode.

Co-Phased 360-Degree Profilometry of Discontinuous Solids with 2-Projectors and 1-Camera

, 2014
Here we describe a co-phased 360-degree fringe-projection profilometer which uses 2-projectors and 1-camera and can digitize discontinuous solids with diffuse light surface. This is called co-phased because the two phase demodulated analytic-signals from

Ion Charge Compensation upon Electrochemical Doping of Redox Polymer Films with Tunable Crosslinking Density

Advanced Electronic Materials, EarlyView.
The electrochemical doping of redox homo‐ and copolymers containing triphenylamine (TPA) as redox‐active units is reported. Electrochemical crosslinking leads to films with tetraphenylbenzidine (TPB) crosslinking units. Advanced electrogravimetric tools are applied to get insights into their mixed ionic‐electronic conducting characteristics: anion ...

Scalable Wheat Bran‐Algae Composites for Edible Electronics with Spray‐Coated Food‐Grade Conductive Inks

Advanced Electronic Materials, EarlyView.
A fully edible wheat bran–algae substrate is fabricated through scalable mould‐compression and spray‐coating, enabling robust, food‐grade platforms for sustainable electronics. A chitosan barrier improves water resistance and ink compatibility, while activated‐carbon conductive films form uniform electrodes with Ohmic behaviour.
