Strategy for One‐Step Optimization of Metal Oxide Passivating Contact Materials for Si Heterojunction Solar Cells through Growth Angle Variation

Small, EarlyView.
A one‐step oblique angle reactive sputtering approach enables simultaneous tuning of bulk and interfacial stoichiometry in a metal oxide/ silicon heterojunction. In case of vanadium oxides, growth angle variation controls the formation of stoichiometric SiO2, ternary SiOx(V) interlayer, and phase purity of vanadium oxide, considerably simplifying the ...

Ballistic Performance Evaluation of Aluminium Plate Impact by Fragment Simulating Projectile

Journal of Physics: Conference Series, 2020
Abstract The ballistic performance has drawn attention to researchers from a military background. They intend to provide solutions to ensure the soldiers in the front line of war do not kill in action. A casualty in war can lead to depression among soldiers and not to mention to their family as well.

Preventing Plasma‐Induced Resist Hardening in Molybdenum Disulfide Transistors via Sacrificial Metal Mask Lithography

Small, EarlyView.
Photoresist (PR) residue significantly degrades the electrical performance of 2D semiconductors such as MoS2. In particular, the intrinsically ultrathin nature of these materials makes them highly susceptible to damage during conventional PR cleaning procedures.

Anisotropy Thermal Properties of Electrically Insulating Thin Films and Sheets: A Review

Small Methods, EarlyView.
Thermally conducting and electrically insulating materials with anisotropy properties play an integral role in advanced thermal management, in particular for electronic devices. This review discusses recent progress in enhancing thermal conductivity and controlling the thermal anisotropy between in‐plane and cross‐plane (through‐thickness) directions ...

A study on the energy dissipation of several different CFRP-based targets completely penetrated by a high velocity projectile [PDF]

, 2009
The threat of fragmenting munitions from MANPADS to civilian and military aircraft has, in recent years, become an ever increasing worry. One of the ways to enhance the protection of CFRP-based composites is to add lightweight materials that can provide ...

Programmable Porosity in Polymers via Microfluidic Templating and 3D Printing

Small Methods, EarlyView.
Fluid templating is a powerful way to produce porous polymers. Microfluidic technologies enable fine control over the dimension and packing of bubbles and droplets. Combined with additive manufacturing, microfluidic templating enables the creation of polymeric functionally graded porous materials in which both porosity and three‐dimensional geometry ...

Inconsistency in 9 mm bullets : correlation of jacket thickness to post-impact geometry measured with non-destructive X-ray computed tomography [PDF]

, 2014
Fundamental to any ballistic armour standard is the reference projectile to be defeated. Typically, for certification purposes, a consistent and symmetrical bullet geometry is assumed, however variations in bullet jacket dimensions can have far reaching ...
