Our latest publication is out now! Led by Jenny, we study charged-neutral polymer blends and show that divalent ion identity strongly influences the nanostructure. we even report microphase separation at lengthscales typically observed in block copolymers! Read it here: pubs.acs.org/doi/10.1021/...

Tunable Nanoscale Structure via Divalent Ion Identity in Charged-Neutral Polymer Blends

Charged-neutral polymer blends, wherein an ion-containing polymer is blended with a neutral polymer, are potential candidates for battery electrolytes due to their improved ion transport properties and electrochemical stability. Though electrostatic interactions in charged polymer blends can theoretically stabilize ordered nanostructures analogous to those observed in neutral block copolymers, direct experimental evidence remains limited. Here, we investigate the effects of divalent cation identity on the nanoscale morphology of charged-neutral polymer blends composed of poly(ethylene oxide) (PEO) and Mg2+ or Ca2+ ion-containing polymers, poly[3-(methylacryloxy)propylsulfonyl-1-(trifluoromethanesulfonylimide)] (P(Mg(MTFSI)2) or P(Ca(MTFSI)2). By tuning the size of the divalent counterion, we are able to precisely tune the ion solvation between the free cation and PEO, which acts as a solvent in this system. Differential scanning calorimetry (DSC) and small-angle X-ray scattering (SAXS) measurements reveal that Mg2+ and Ca2+ ions induce distinct structural behavior. In both systems, the blends become more miscible as the concentration of ion-containing polymer is increased indicated by increased suppression of PEO crystallinity. At the highest concentrations of P(Mg(MTFSI)2), the blends undergo microphase separation and generate nanostructures with short-ranged ordering. In contrast, calcium ions, which are more readily solvated by PEO, produce more homogeneous blends characterized by a single glass-transition temperature and featureless SAXS data. The results demonstrate the novel experimental confirmation that charged-neutral polymer blends can undergo microphase separation and show that counterion identity can be exploited as a design parameter to control nanoscale morphology.

the second Loo Lab paper is out! here we use a combined SAXS/SANS approach to study the phase behavior of charged-neutral polymer blends. despite being macroscopically miscible, these blends form disordered nanostructures due to ionic interactions pubs.acs.org/doi/full/10....

The Influence of Charge Correlation and Ion Solvation on the Phase Behavior of Single-Ion Conducting Polymer Blend Electrolytes Using SAXS/SANS

Single-ion conducting polymer blends (SICPBs) have demonstrated exceptional electrochemical performance as solid-state battery electrolytes; however, their nanoscale morphology and thermodynamic behavior remain unexplored. In this work, we investigate blends composed of deuterated poly(ethylene oxide) and poly[lithium sulfonyl(trifluoromethane sulfonyl)imide methacrylate], dPEO/P(LiMTFSI), and report the first experimental study of the nanostructures of charge-neutral polymer blends using small-angle neutron scattering (SANS) and small-angle X-ray scattering (SAXS). Despite the macroscopic miscibility indicated by a single glass-transition temperature, SANS and SAXS results reveal disordered, charge-correlated nanostructures that are strongly influenced by blend composition and temperature. At low concentrations of charge polymer, the scattering is dominated by concentration fluctuations, and the random phase approximation is applied to extract values of the Flory–Huggins interaction parameter, χSC. At higher charged polymer content, concentration fluctuations are suppressed, and a correlation model is used to characterize the nanostructures of the charge correlations. We find that the structures of the charge correlations are highly dependent on blend composition─consistent with predictions from Sing’s self-consistent field theory-liquid state models. Understanding these features is essential for uncovering the ion transport mechanism that leads to improved electrochemical performance previously reported in SICPB systems.

🚨🚨 Deranged letter from Education Secretary Linda McMahon to Harvard’s president, cutting off federal funding for any new grants. Worth reading in full. It is NUTS.

THE SECRETARY OF EDUCATION
WASHINGTON, DC 20202
May 5, 2025
Dr. Alan Garber
Office of the President
Harvard University
Massachusetts Hall
Cambridge, MA 02138
Dr. Garber,
The Federal Government has a sacred responsibility to be a wise and important steward of American taxpayer dollars. Harvard University, despite amassing a largely tax-free $53.2 billion dollar endowment (larger than the GDP of 100 countries), receives billions of dollars of taxpayer largess each year. Receiving such taxpayer funds is a privilege, not a right. Yet instead of using these funds to advance the education of its students, Harvard is engaging in a systemic pattern of violating federal law. Where do many of these "students" come from, who are they, how do they get into Harvard, or even into our country—and why is there so much HATE? These are questions that must be answered, among many more, but the biggest question of all is, why will Harvard not give straightforward answers to the American public?
Harvard University has made a mockery of this country's higher education system. It has invited foreign students, who engage in violent behavior and show contempt for the United States of America, to its campus. In every way, Harvard has failed to abide by its legal obligations, its ethical and fiduciary duties, its transparency responsibilities, and any semblance of academic rigor. It had scrapped standardized testing requirements and a normalized grading system. This year Harvard was forced to adopt an embarrassing "remedial math" program for undergraduates.
Why is it, we ask, that Harvard has to teach simple and basic mathematics, when it is supposedly so hard to get into this "acclaimed university"? Who is getting in under such a low standard when others, with fabulous grades and a great understanding of the highest levels of mathematics, are being rejected?
Harvard has even been embroiled in humiliating plagiarism scandals, exposed clearly and plainly in the media, with respect to your then…

$running the institution in a totally chaotic way. Harvard alumnus and highly successful hedge fund manager Bill Ackman noted that, under her leadership, Harvard has become "a political advocacy organization for one party." Ackman has called for the resignation of Pritzker, concluding that the "[t)he mismanagement here is Penny Pritzker" and noting that any serious corporation would have removed her after a litany of recent failings and the fact that, incredibly, "Harvard is not in a good financial position." According to Ackman, one of the world's foremost finance experts, Harvard's so-called S53 billion endowment is "massively overstated as far as what it's really worth," and Harvard has irresponsibly taken out $8 billion in debt. If this is true, it is concerning evidence of Harvard's disastrous mismanagement, indicating an urgent need for massive reform-not continued taxpayer investment. If Harvard prefers not to change, then Harvard should have no problem using its overflowing endowment to fund its bloated bureaucracy. At its best, a university should fulfill the highest ideals of our Nation, and enlighten the thousands of hopeful students who walk through its magnificent gates. But Harvard has betrayed this ideal. Perhaps most alarmingly, Harvard has failed to abide by the United States Supreme Court's ruling demanding that it end its racial preferencing, and continues to engage in ugly racism in its undergraduate and graduate schools, and even within the Harvard Law Review itself. Our universities should be bastions of merit that reward and celebrate excellence and achievement. They should not be incubators of discrimination that encourage resentment and instill grievance and racism into our wonderful young Americans. The above concerns are only a fraction of the long list of Harvard's consistent violations of its own legal duties. Given these and other concerning allegations, this letter is to inform you that Harvard should no longer seek GRANTS from the fede…$

Federal Agencies. The Administration's priorities have not changed and today's letter marks the end of new grants for the University.
These requests will advance the best interests of Harvard University, so it can reclaim its status as a respected educational institution for the future leaders of America. Thank you for your attention to this matter!
Sincerely,
Linda E. McMahon
Secretary of Education
