The no-defect conjecture in cosmic crystallography

, 1996
The topology of space is usually assumed simply connected, but could be multi-connected. We review in the latter case the possibility that topological defects arising at high energy phase transitions might still be present and find that either they are ...

Laser‐Induced Graphene from Waste Almond Shells

Advanced Functional Materials, EarlyView.
Almond shells, an abundant agricultural by‐product, are repurposed to create a fully bioderived almond shell/chitosan composite (ASC) degradable in soil. ASC is converted into laser‐induced graphene (LIG) by laser scribing and proposed as a substrate for transient electronics.

Crystal structure of rhodopsin bound to arrestin by femtosecond X-ray laser. [PDF]

, 2015
G-protein-coupled receptors (GPCRs) signal primarily through G proteins or arrestins. Arrestin binding to GPCRs blocks G protein interaction and redirects signalling to numerous G-protein-independent pathways.

Smart Nanogels as Enzyme‐Driven Nanomotors for Navigating Viscous Physiological Barriers

Advanced Functional Materials, EarlyView.
Two families of urease‐powered nanomotors (NMs), with and without a p‐(2‐hydroxyethyl methacrylate) (p‐HEMA) shell, have been successfully prepared. Both types exhibit effective motion in highly viscous synovial fluid media at low urea concentrations (25 mM).

Crystallography and Geopolitics [PDF]

Science, 2014
Developed and developing nations recognize that innovation is key to their economies. Connecting this with the discipline of crystallography may not seem immediately apparent, but during the past century, understanding the structure of matter has transformed industries and created new frontiers, from the design of new medicines and materials to ...

Phyllotaxis: Leaf arrangement on a horizontal branch and crystallographic borders

Vestnik MGTU
Phyllotaxis is an orderly arrangement of leaves on plant stems and branches. The natural reason of this arrangement is that each species based on the habitat conditions in the course of evolution in one way or another solved the problem of optimising the
