Marc Halpern shared thisMost organic chemical processes leave cost savings on the table. Live webinar May 20: how to identify when PTC can fix that. For process chemists and managers working in organic chemical manufacturing (agrochemicals, pharmaceuticals, polymers, flavors & fragrances, and related areas), the graphic below summarizes where Phase-Transfer Catalysis (PTC) most often delivers value, both in terms of process performance and reaction types. In practice, the biggest gains typically come from: • Higher yields • Reduced cycle time (higher plant throughput) • Replacing expensive hazardous strong base with NaOH • Eliminating or simplifying solvent systems • Reducing excess expensive or hazardous reactants These are not marginal improvements, they directly impact: • Cost of goods • Capacity constraints • Process robustness If your processes involve: • Nucleophilic substitutions • Strong base chemistry • Biphasic or heterogeneous systems —there is a strong probability that PTC is worth evaluating. I’ll walk through a practical framework for identifying these opportunities in a live session on May 20. 👉 Register here: https://lnkd.in/d2UiN3Hx

Marc Halpern shared thisA SHELF FULL OF FORGOTTEN SIGNALS I noticed something today that I hadn’t paid attention to in at least ten years. A single shelf in my living room. I hadn’t touched it, moved it, or even really looked at it in a decade (since I put the 2015 World Series book there)… but when I finally did, it felt less like a bookshelf and more like a snapshot of how I used to think. On that one shelf: * Business planning tools from the early 1990s * Books on leadership, negotiation, and strategy * Personal development and mindset * A deep dive into a major historical war * Even a few interests that I haven’t revisited in years And then there was one item that stopped me. BizPlan Builder, a piece of software on a 5¼-inch floppy disk that I used in 1992 to write my first business plan. No cloud. No AI. Just an idea… and the decision to take it seriously enough to put structure around it. Seeing that again brought back something I hadn’t thought about in a long time: At one point, I wasn’t just interested in business. I was actively building something. That shelf made me realize something simple, but powerful: We don’t just collect books. We collect evidence of who we were becoming at different points in our lives. Some of those interests stay with us. Some fade. Some quietly disappear because life got busy. And occasionally, something worth revisiting gets left behind. What struck me most wasn’t what was on the shelf. It was what wasn’t. The gap between what once captured my attention and how I actually INVEST my time today. That gap tells a story. Here’s a simple exercise: Take a look at a shelf, drawer, or box you haven’t touched in ten years. What do those books say about who you were becoming? More importantly, how much of your time today reflects what mattered to you back then? If something stands out, drop it in the comments. And if you’re up for it, share a photo. I’d be curious what stories are hiding on your shelf.

Marc Halpern shared thisIf you are analytical and if you want to be successful as a PASSIVE investor, you might want to watch my November 2025 presentation on “7 Valuable Lessons I Learned as a Private Placement Investor.”Marc Halpern shared thisIn this powerful and practical talk, Marc Halpern, founder of Deep Due Diligence Investors, shares the 7 most valuable lessons he’s learned from decades of investing in private placements. From the pain of losing 100% on a deal tied to macro events, to using AI tools and team-based diligence to evaluate hundreds of offerings annually, Marc walks through real-world stories and data-backed principles that every passive investor needs to hear. You’ll learn: - Why you can’t eliminate risk but how to manage and minimize it - The difference between “lazy diligence” and deep due diligence that actually works - How to evaluate the sponsor (“jockey”), the deal (“horse”), and the market (“track”) - Why diverse perspectives in investment teams lead to better outcomes - How Marc uses AI tools like portfolio matchers, deal screeners, and due diligence assistants - The power of true diversification across 15 asset classes - Why high deal flow is critical to finding quality - And the one bonus rule: Face-to-face still matters most https://lnkd.in/eUG9Jv5U7 Valuable Lessons I Learned For Effective Placement Investing | Marc Halpern7 Valuable Lessons I Learned For Effective Placement Investing | Marc Halpern

Marc Halpern posted thisROLE OF BRAIN AND BODY I’m in my early 70’s and I create content in as many fields as possible, all the time, except when I’m sleeping. My body is verifiably in my 70’s. But my mind is in my 20’s. In other words, my brain enjoys 70+ years of experience with the energy of a 20-year old. The role of the rest of my body is to carry around my brain from place to place so it can enjoy whatever those places have to offer. I will be launching a K-3 program for decision literacy in 2026 that I just created and I have no formal credentials in education or psychology. I do things like this because I can. The role of my body is to port my brain from one place to another. Think about what you are capable of doing with your brain and your body.

Marc Halpern reposted thisMarc Halpern reposted thisSometimes, Chemistry can look like Magic… 💥 But it isn’t Magic… It’s alignment. It’s timing. It’s shared values meeting shared ambition. In Business, Leadership, and Partnerships, we often describe great collaborations as having “Chemistry.” What we’re really experiencing is: ✅ Clear Communication ✅ Mutual Respect ✅ Complementary Strengths ✅ Emotional Intelligence ✅ A shared Vision of Success When these elements combine, the outcome can feel effortless. Ideas Flow. Problems Shrink. Energy Multiplies. Results Accelerate. From the outside, it looks like Magic. From the inside, it’s Intentional. The strongest Teams, the most successful Leaders, and the most impactful Partnerships don’t rely on luck. They invest in Trust. They build Clarity. They nurture Alignment. Chemistry isn’t accidental… It’s Cultivated. #Leadership #Teamwork #Entrepreneurship

Marc Halpern shared thisI was in Roatan last week and I saw these two waste bins. I took a picture for my chemist friends. The irony is that”inorganic” likely refers to organic compounds such as paper and plastic in addition to cans. Your thoughts?

Marc Halpern liked thisMarc Halpern liked thisFor a long time, society gave mothers labels: single mothers, stepmothers, biological mothers, adoptive mothers, working mothers, stay-at-home mothers, Type A mothers. The list goes on and on. And somewhere along the way, many women were taught that the badge of honor was self-sacrifice. To put others first, to carry a lot on their plate, and to lose themselves quietly while everyone praised how much they could handle. That dynamic might still work for a lot of people…but it no longer works for many mothers. The new type of mother understands that protecting her well-being does not only honor herself, it also models how her children will treat themselves in the future. She is becoming aware of the invisible mental load she has carried for years. And she is no longer accepting weaponized incompetence disguised as “women are just better at it.” Nope. The new mother is questioning old expectations. She is asking for support without shame. She is standing tall for healthy relationships. She is allowing herself to rest. To dream, to make mistakes, and to evolve. The new mother knows the power she carries. And she is setting a new tone for this generation and the next. And that is beautiful. Happy Mother’s Day to every woman redefining what motherhood can look like. 🤍 #MothersDay #ModernMotherhood #WomenSupportingWomen

Marc Halpern reacted on thisMarc Halpern reacted on thisAfter 8 months of work, I finally published the book I’ve been working on. Strategic Engineering for Small Manufacturers — Develop Like the Titans (Without the Red Tape) Most small and midsize manufacturers don’t struggle with product development because they lack talent, they struggle because their process breaks down. Projects stall. Launches get delayed. Teams fall into constant firefighting. Good ideas never make it past discussion. The same problems show up again and again, costing time, money, and momentum. Meanwhile, larger organizations tend to operate differently. They align product development decisions with business goals, reduce risk early, and bring products to market with far fewer surprises. The difference isn’t resources, It’s product engineering strategy. This book is my attempt to translate that into something practical for smaller teams — without adding unnecessary process or bureaucracy. If you’re leading a product-based company and this sounds familiar, I’d be interested to hear how you’re approaching this.

Demonstrating rational structural design of compounds can reverse activity while maintaining target specificity, re-engineering SMU-L11, a TLR7 agonist into TLR7/8-specific antagonists represents a viable therapeutic strategy for the treatment of psoriasis Employing a SBDD approach to rationally design and synthesize novel small molecule TLR7/8 dual antagonist, the study identified SMU-R39 as an optimal compound, exhibiting potent TLR7/8 inhibitory activity, wherein experimental validation revealed that structural restriction of the N1 substituent was critical for the pharmacological efficacy of the inverted parent scaffold Binding directly to TLR7/8, SMU-R39 strongly suppressing the in vitro downstream inflammatory cascade, thereby significantly reducing the secretion and transcription of pro inflammatory cytokines in immune cells Furthermore, in vivo studies demonstrated SMU-R39 to markedly alleviate murine psoriasis-like skin inflammation and ameliorate psoriasis in mice without inducing systemic toxicity https://lnkd.in/gPwHjrNX Zhipeng Chen et al

Understanding your solvent’s properties should be the deciding factor of what equipment you use or don’t use. Unfortunately in this business pressure does not make diamonds its just Henry’s law in full effect. In a closed system, with volatile solvents, translating how Henry’s law affects solubility is where thermodymagic meets science. Your solvent choice and understanding the SOLUTION you have made should dictate whether you use BALL jars, PYREX pans, Evaults or miners in the post extraction process . . . . . . . #webeendoingthis #nothingnew #thca #butane #bho #hash #diamondalchemy #nopuckallstack #thcatech #cannabis #extraction #hte #diamonds #labsupply #solvent #solventsupply #cannabisextraction #solventextraction #THCaIsolate Top Secret Workshop Christian Sutton

Chemists have developed synthetic plastics that self-destruct at pre-determined speeds by mimicking the molecular structure of DNA, potentially solving the global accumulation crisis. A team from Rutgers University successfully engineered polymers that break down under everyday conditions without requiring heat or harsh chemicals, reports Nature Chemistry. The innovation mimics the “helper groups” found in natural polymers like DNA and RNA, which allow biological materials to degrade once their purpose is served. “Biology uses polymers everywhere, such as proteins, DNA, RNA and cellulose, yet nature never faces the kind of long-term accumulation problems we see with synthetic plastics,” said Yuwei Gu, assistant professor in the Department of Chemistry and Chemical Biology at Rutgers. The researchers arranged the plastic’s chemical components to create a “pre-folded” structure, similar to creasing a piece of paper so it tears easily along a specific line. This structural manipulation allows the material to break apart thousands of times faster than conventional plastics when triggered, whilst maintaining strength during use.

Ever wondered how 'oil-control' primers actually stop the shine? It’s not magic...it’s molecular storage! ❄️ In this demo I use instant snow, these polymers can absorb massive amounts of liquid without feeling wet. They trap the oil inside their physical structure, locking it away so it can’t break down your makeup. While this instant snow absorbs water, your primer uses similar 'oil-loving' polymers to do the exact same thing to your sebum. It’s basically a micro-sponge for your pores. Your skin stays matte and 'dry' because the oil is trapped inside the polymer, not sitting on your face! Follow for more beauty science 👩🏾🔬💄

In July 2025, the Granado Institute obtained a new patent from the USPTO (USA) for a novel process for producing superabsorbent polymers (SAPs) from polyacrylonitrate (PAN) and recycling its fibers, known commercially as acrylic fibers. This is the first known chemical recycling process for this fiber, which has a global annual use of 2 million tons. The superabsorbent polymer obtained from this recycling process has a swelling ratio greater than 250 g H2O/g of polymer, and its potassium form is already approved for agricultural use by the Brazilian Ministry of Agriculture and is marketed under the brand name "HIDROSILO."

Spectroscopic PAT should be as transformative for R&D as it is in commercial manufacturing, enabling faster development, better process control, and real‑time insight. But the reality is that the calibration burden of chemometric models remains a major barrier to adoption. There’s a more practical path forward: lean chemometrics. This article proposes and formalizes lean chemometrics as MVDA methods designed to address calibration burden and discusses practical integration considerations for common pharmaceutical PAT applications.
