Low-dimensional copper coordination polymers represent an alternative, unprecedented class of charge transport materials, comprised molecular building blocks.

Despite the paramount role of drylands in supporting people’s livelihoods and rendering ecosystem services, legislation on Environmental Impact Assessment has been introduced belatedly after several decades. By exemplifying Iran, author proposes two main reasons for such a delayed action. First, are misleadingly considered as barren lands where biodiversity is relatively low. In one classificat...

The presidency of Donald Trump represented an unprecedented low point in transatlantic relations. When Joe Biden took power early 2021, his administration launched several policy initiatives suggesting that the new would continue to allow seemingly long-term weakening relationship continue. A significant part literature on recent developments relations points same direction, namely a cooperatio...

Porous carbon spheres with unique structures and morphologies are prepared from energetic carbon precursors, alkali propiolates, via ultrasonic spray pyrolysis. Aerosolized liquid droplets containing alkali propiolates act as microreactors that confine the thermal decomposition of energetic precursors and lead to the formation of several unprecedented carbon morphologies.

A new spectral code for constructing general–relativistic models of rapidly rotating stars with an unprecedented accuracy is presented. As a first application, we reexamine uniformly rotating homogeneous stars and compare our results with those obtained by several previous codes. Moreover, representative relativistic examples corresponding to highly flattened rotating bodies are given.

The RAF inhibitor vemurafenib has unprecedented activity in BRAF-mutant melanomas, but resistance invariably develops. As Hsp90 is required for the stability of several of the oncoproteins that mediate RAF inhibitor resistance, inhibitors of this cellular chaperone may be effective in patients with intrinsic or acquired resistance to RAF inhibitors.
