Casimir Thrust Force on a Rotating Chiral Particle

, 2018
In the work, the thermal and vacuum fluctuation is predicted capable of generating a Casimir thrust force on a rotating chiral particle, which will push or pull the particle along the rotation axis. The Casimir thrust force comes from two origins: i) the rotation-induced symmetry-breaking in the vacuum and thermal fluctuation and ii) the chiral cross ...

THRUST FORCE ANALYSIS OF SPIKE BELL NOZZLE

International Journal of Applied Research in Mechanical Engineering, 2013
Aerospike nozzle is often described as an inside-out bell shaped nozzle and named for its prominent spike located at centre. This project mainly focuses on design of various types of nozzles such as aerospike, truncated aerospike and spike bell nozzles.

Non‐Monotonic Changes in the Thermal Conductivity of Conjugated Polymer Films with Increasing Levels of Chemical Doping

Advanced Functional Materials, EarlyView.
Thermal conductivity changes non‐monotonically as regioregular (RR) and regiorandom (RRa) P3HT films are doped with F4TCNQ as a function of the extent to which P3HT is doped: an increase in thermal conductivity is observed upon lightly doping P3HT compared to the undoped film, followed by a decrease in the heavily doped regime. ABSTRACT The performance

Monolithic Oxidation Enables Ultrathin Vertically Graded Tantalum Oxide for Low‐Voltage, Low‐Variability Memristive Switching

Advanced Functional Materials, EarlyView.
Monolithic UV‐ozone oxidation of Ta forms an ultrathin Ta2O5/TaOx bilayer enabling resistive switching with a vertical defect gradient. A stoichiometric surface layer over an oxygen‐deficient sublayer promotes localized filament nucleation near the top interface, enabling low‐voltage operation, and reduced cycle‐to‐cycle variability.

Chemically Fueled Systems Chemistry Across Length Scales

Advanced Functional Materials, EarlyView.
Chemically fueled reaction cycles regulate processes through single and multiple catalytic sites on the molecular and assembly scale. This gives rise to unique kinetically controlled properties/functions like spatio‐temporal catalysis, oscillations, optical properties, and perform work.

Tunable Complementary Doping Strategy Enables High‐Performance Homo‐Channel CMOS in Monolayer WSe2

Advanced Functional Materials, EarlyView.
Polarity‐selective modulation enables a homo‐channel WSe2 CMOS platform from a single 2D semiconductor. MoOx and AlN tune WSe2 toward p‐ and n‐type operation, respectively, yielding complementary FETs and inverters with balanced switching, high voltage gain, low static power, and promising scalability for 2D logic integration.
