A bacterial gene-drive system efficiently edits and inactivates a high copy number antibiotic resistance locus. [PDF]

, 2019
Gene-drive systems in diploid organisms bias the inheritance of one allele over another. CRISPR-based gene-drive expresses a guide RNA (gRNA) into the genome at the site where the gRNA directs Cas9-mediated cleavage.

MXene‐Coated 3D Printed Horn Antennas for Ku Frequency Band

Advanced Materials Technologies, EarlyView.
An additive manufacturing approach to 3D printing horn antennas and coating them with Ti3C2Tx MXene is proposed. Rapid fabrication of lightweight, high‐performance antennas operating in the Ku‐band (12.4–18 GHz) has been demonstrated. The MXene‐coated antennas exhibit comparable electromagnetic performance to conventional, costly aluminum ones, with ...

Non‐Invasive Multidimensional Capacitive Sensing for In Vivo Traumatic Brain Injury Monitoring

Advanced Materials Technologies, EarlyView.
Single‐electrode, multidimensional capacitive sensors noninvasively assess cerebral autoregulation and compliance for traumatic brain injury monitoring. ABSTRACT Traumatic brain injury (TBI) is a major cause of death and disability, but invasive intracranial pressure (ICP) monitoring is risky, and current non‐invasive methods lack the resolution and ...

Molecular Inks for the Development of Complex 3D In‐Mold Electronics

Advanced Materials Technologies, EarlyView.
Molecular inks (MINKs) enable the fabrication of thermoformed 3D circuits by decoupling the forming and metallization steps. Following thermoforming, intense pulsed‑light or thermal processing converts the patterned MINKs into complex 3D conductive tracks with improved stretchability and electrical performance, advancing low‑cost, high‑performance in ...
