High Aspect Ratio, Superconducting Vacuum Gap Capacitor NEMS with Plate Distances Down to 32 nm

open access: yesAdvanced Materials Technologies, EarlyView.
Fabrication of aluminium vacuum gap capacitor based NEMS is investigated with a free to move top electrode. To avoid collapse of the top electrode vertical stress gradient is controlled through sputter parameters. The result is wafer‐level high‐yield fabrication of vacuum gap capacitors with radii between 7 µm and 30 µm and integrated piezoactuators. A

Formulation and evaluation of sustained release matrix tablet of rabeprazole using wet granulation technique

open access: yesJournal of Pharmacy and Bioallied Sciences, 2014
Introduction: Rabeprazole, a member of substituted benzimidazoles, inhibits the final step in gastric acid secretions. This drug claims to cause fastest acid separation (due to higher pKa), and more rapidly converts to the active species to aid gastric ...

Microlasers Made Entirely from Edible Substances

open access: yesAdvanced Optical Materials, EarlyView.
Several types of microlasers made completely out of edible substances are developed. They can be embedded directly into edible products and enable the sensing of various parameters, including sugar concentration, pH, the presence of bacteria, and exposure to too‐high temperatures.

Emerging Therapeutic Strategies for Hearing Loss

open access: yesAdvanced Therapeutics, EarlyView.
Challenges still exist in treating hearing loss in cases of severe damage to hair cells or spiral ganglion neurons. Here, a schematic diagram of cochlear sensory hair cells and auditory nerves is presented. It is found that in normal Corti organs, hair cells have upright stereocilia at the top and auditory neurons at the base. Ototoxic drugs, noise, or
