Analysis and design for the comprehensive ballistic and blast resistance of polyurea-coated steel plate

Defence Technology, 2023
Fragments and blast waves generated by explosions pose a serious threat to protective structures. In this paper, the impact resistance of polyurea-coated steel plate under complex dynamic loading is analyzed and designed for improving comprehensive ...

Resistance to Overdoping Allows Over 2000 S cm−1 Conductivity in P(g3BTTT) With Anion‐Exchange Doping

Advanced Materials, EarlyView.
Anion‐exchange doping of conjugated polymers is an effective way to achieve high conductivities. Here, we report over 2000 S cm−1 electrical conductivity for doped P(g3BTTT). In addition, we show that P(g3BTTT) sustains exceptionally high doping levels without any drop in the charge mobility.

A facile method for the estimation of ceramic performance in light armor systems

International Journal of Ceramic Engineering & Science
Ballistic armor material development has been historically constrained by the limitations of existing predictive models. Traditional approaches, primarily reliant on finite element models, are not only computationally intensive but also often fall short ...

Ballistic performance of lightweight ceramic-metal composite armour plates under blunt projectile impact

Composites Part C: Open Access
The importance of well-designed armour for mitigating threat to life cannot be overemphasized. Possibility of single and multi-layered configurations, various potential materials and their sequence and the gap in between makes the design of effective ...

Bandgap‐Dependent Band‐to‐Band Tunneling in Carbon Nanotube Transistors

Advanced Materials Interfaces, EarlyView.
We systematically investigate bandgap‐dependent BTBT in SWCNT transistors by comparing wide‐bandgap (6,5) (Eg≈1.13 eV), medium‐bandgap HiPco, and narrow‐bandgap Arc‐discharge (Eg≈0.59 eV) SWCNT networks. The narrow‐bandgap networks show stronger BTBT, higher off‐state leakage, and lower on/off ratio, while wide‐bandgap (6,5) devices suppress BTBT and ...

Deep‐Tissue Light Generation via Whispering Gallery Mode Lasing From a Commercial Nylon Fiber for Biomedical Applications

Advanced Materials Technologies, EarlyView.
A dyed nylon fiber is implemented inside the scattering phantom and skin tissue. The deep‐tissue light generation via whispering gallery mode lasing is demonstrated, achieving a depth of >50 times transport mean free path in scattering phantom and 3 mm beneath skin.

Ultrasound‐Actuated Gene Editing in Human Kidney Organoids

Advanced Science, EarlyView.
Peptide‐stabilized nanoemulsions enable spatially controlled, ultrasound‐triggered delivery of gene‐editing proteins deep within human kidney organoid tissues. Focused acoustic pulses drive droplet vaporization, propelling cargo into target renal cells while preserving native tissue microarchitecture. This non‐viral platform improves both the depth and

The ballistic performance of the bombard Mons Meg

Defence Technology, 2016
AbstractThe bombard Mons Meg, located in Edinburgh Castle, with a diameter of 19 inches (48 cm), was one of the largest calibre cannons ever built. Constructed in 1449 and presented to King James II of Scotland in 1454, Mons Meg was used in both military and ceremonial roles in Scotland until its barrel burst in 1680.

Flexoelectricity in Photoconversion: Fundamentals, Materials, and Outlooks

Advanced Science, EarlyView.
Mechanical bending of a flexible cantilever induces a strain gradient in the photoactive material. The resulting flexoelectric field couples with photovoltaic and photoconductive effects, modulating charge generation, separation, and collection. A comparative analysis of oxide perovskites, halide perovskites, and two‐dimensional materials is presented,
