The readme file further describes the individual data.These files contain data along with the associated output from instrumentation supporting all results reported in "Superlattice by charged block copolymer self-assembly" by Shim et. al. We report the discovery of an intriguing superlattice morphology from compositionally symmetric charged block copolymers, poly[(oligo(ethylene glycol) methyl ether methacrylate–co–oligo(ethylene glycol) propyl sodium sulfonate methacrylate)]–b–polystyrene (POEGMA–PS). These materials are conveniently prepared by sequential reversible addition–fragmentation chain transfer (RAFT) polymerization, followed by introduction of charged groups, in a manner that allows for systematic variation of the molecular structure in general, and the charge content in particular. POEGMA–PS self-assembles into a superlattice lamellar morphology, a previously unknown class of diblock nanostructures, but strikingly similar to oxygen-deficient perovskite derivatives, when the fraction of charged groups in the POEGMA block is about 5–25%. The charge fraction in the POEGMA block, and the tethering of the ionic groups, both play critical roles in driving the formation of the superlattice. This study highlights the accessibility of novel morphologies by introducing charges in a controlled manner.The Office of Basic Energy Science (BES) of the U.S. Department of Energy (DoE), under Contract DE-FOA-0001664.Shim, Jimin; Bates, Frank S; Lodge, Timothy P.

Supporting data for Core−Shell Gyroid in ABC Bottlebrush Block Terpolymers
No full textThe data folder contains all small-angle X-ray scattering (SAXS) data, as well as proton nuclear magnetic resonance (1H NMR), size exclusion chromatography (SEC), differential scanning calorimetry (DSC), and transmission electron microscopy (TEM) data. The nomenclature is consistent with that used in the manuscript. See the readme.txt file for further details.These files contain primary data supporting all results reported in Cui et al. "Core−shell gyroid in ABC bottlebrush block terpolymers." A series of bottlebrush block polymers containing 24 PEP-PS diblock copolymers and 109 PEP-PS-PEO triblock terpolymers were synthesized by ring-opening metathesis polymerization (ROMP) of norbornene-functionalized poly(ethylene-alt-propylene) (PEP), poly(styrene) (PS), and poly(ethylene oxide) (PEO) macromonomers. The molecular weights of the three macromonomers were around 1 kg/mol. The relatively modest total backbone degrees of polymerization ranged from ca. 20 to 40. Morphologies of these bottlebrush block polymers were characterized by small-angle X-ray scattering (SAXS). The PEP-PS diblocks exhibited only cylindrical (HEX) and lamellar (LAM) morphologies; the desired network phases did not appear in these materials, consistent with previous experimental studies. However, adding variable-length bottlebrush PEO blocks to diblocks containing 30% to 50% PS led to a substantial core-shell double gyroid (GYR) phase window in the ternary phase portrait. Encouragingly, the GYR unit cell dimensions increased almost linearly with the backbone degree of polymerization, portending the ability to access larger network dimensions than previously obtained with linear block polymers. This finding demonstrates a periodic network phase in bottlebrush block polymers for the first time and highlights extraordinary opportunities associated with applying facile ROMP chemistry to multiblock bottlebrush polymers.National Science Foundation, DMR-2011401U.S. Department of Energy Office of Science, DE-AC02-06CH11357Cui, Shuquan; Zhang, Bo; Shen, Liyang; Bates, Frank S; Lodge, Timothy P.

A MISSING BROTHER.
Alfred J. Barnes, member (In good standing) of Nevada (Mo.) Lodge. B. P. O. Elks. disappeared from his home at Stillwater, Oklahoma, on or about October 8, 1902, and since then not one word has been heard from him. Brother Barnes conducted a large retail clothing business at Stillwater and left a wife, who is still at Stillwater.
DESCRIPTION.
Brother Barne was 32 years of age; light complexion, large dark brown eyes; dark hair; prominent ears; heavy eyebrows; slight upper curl to lip corners; weight about 175lbs.; height 5ft. 10 Inches; when last seen wore grey sack suit; diamond In tie and diamond rings. Inveterate smoker, hair parted In the middle, accompanying picture taken one year ago; wore chain locket containing small diamond on one aide, on reverse side a monogram “A. J. B.", carried watch in upper left vest pocket. Any information obtained regarding the missing brother will be gratefully received by his parents, wife and friends.

Quantum surveillance and 'shared secrets'. A biometric step too far? CEPS Liberty and Security in Europe, July 2010
No full textIt is no longer sensible to regard biometrics as having neutral socio-economic, legal and political impacts. Newer generation biometrics are fluid and include behavioural and emotional data that can be combined with other data. Therefore, a range of issues needs to be reviewed in light of the increasing privatisation of ‘security’ that escapes effective, democratic parliamentary and regulatory control and oversight at national, international and EU levels, argues Juliet Lodge, Professor and co-Director of the Jean Monnet European Centre of Excellence at the University of Leeds, U
