The Chemical Review journal has posted a review article on the The Role of Ligands in the Chemical Synthesis and Applications of Inorganic Nanoparticles.

The ACS Nano journal has released a virtual issue on Perovskites Nanocrystals. Topics include:

• Colloidal synthesis and post-synthetic transformations
• Bright, tunable emission and blinking dynamics
• Applications in optoelectronics and beyond

The papers appear to be open access at the moment.

The Physical Review journal is celebrating its 125th anniversary. It began publishing in 1893 at Cornell University. The American Physical Society (APS) was founded in 1899 and took over publish the journal in 1913. The Physical Review has a long history of publishing physical discoveries and has posted a fascinating timeline of major discoveries.

Researchers have captured the layer-by-layer growth of a GaAs nanocrystal on video using an electron microscope. The nanocrystal grows under a droplet of liquid gold. A summary of the research and video are reported at Focus: Video—Growing a Crystal One Atomic Layer at a Time, and the paper Atomic Step Flow on a Nanofacet can be found at the APS website.

LTspice and PSPICE models and simuluations for most examples shown in the third edition of R. Jacob Baker's book CMOS Circuit Design, Layout, and Simulation are available at his website. Both simulation example packages are easy to unzip and run. The PSPICE version seems to run on the ORCAD/PSPICE lite version (as least for the few dozen I tried). I've enjoyed reading the first few chapters of the book and the simulation examples are impressive and nicely done.

Phillip Allen has posted notes from his 2016 CMOS Analog Circuit Design short course. There are 40 lectures in all covering submicron, deep submicron, ultra-deep submicron CMOS process technology, PN junctions, small signal models, amplifies, buffers, opamps, comparators, DACs, and ADCs to name a few.

The American Physical Society (APS) has published the 60th anniversary issue of the Review of Particle Physics. This 1898 page two volume set lists tables of measured data on particles, formulas, and has review papers on statistics, particle detectors, colliders, dark mater, and Higgs Boson physics to name a few. It can be downloaded as a pdf (see link above) or found at the Particle Data Group website.
